Doctor Tax Strategies for High-Income Physicians: Cutting the Effective Rate from 45% Toward 30%

A mid-career physician earning $550K of W-2 from a hospital plus $120K of 1099 telehealth income hands the IRS and California roughly $260K every April. That’s a 39% effective rate before payroll tax. Doctor tax strategies high income planning isn’t about magic — it’s about stacking five or six legal moves that each shave 2-6 points off the effective rate. We’re talking the §199A SSTB phase-out at $241,950 single / $483,900 MFJ in 2026, the cash balance plan + 401(k) profit-sharing stack that can park $300K+ pre-tax, the W-2 vs 1099 income split, PSLF and REPAYE coordination for residents and early-career attendings, and the §269A personal service corporation trap that catches doctors who set up a loan-out PSC instead of an S-corp. Half the physicians we onboard have at least one of these moves wrong. The rest are leaving $40K-$120K on the table annually. This post walks through the playbook — the IRC sections, the dollar thresholds, the forms, and where the IRS draws lines that bite when crossed. Real numbers, not platitudes.

Why doctors pay more tax than almost anyone — and where the leaks are

Physicians sit in a structural tax trap. Compensation is high (BLS Occupational Employment Statistics put physician median wage at $239,200 for 2024, with surgeons, anesthesiologists, and radiologists clearing $350K-$500K median). The income is mostly W-2 from hospitals or large groups, which means full federal income tax, full FICA up to the Social Security wage base ($176,100 in 2025, projected $182,400 in 2026), full Medicare with the 0.9% additional Medicare tax above $200K single / $250K MFJ, and the 3.8% Net Investment Income Tax on passive income above those same thresholds.

Stack the highest federal bracket (37% above $626,350 single / $751,600 MFJ for 2025, indexed up for 2026) onto a state like California (13.3% top rate, going to 14.4% with the SDI uncap) and you’re past 50% marginal. A neurosurgeon at $750K all-W-2 in San Francisco hands roughly $320K to government before the property tax bill arrives.

The leaks are predictable. Most physicians I see are doing three or four of these wrong: (1) operating a 1099 side practice as a sole prop instead of an S-corp, (2) ignoring the §199A SSTB phase-out math because they assume they don’t qualify, (3) maxing only the 401(k) at the hospital instead of stacking a defined benefit cash balance plan on top of the 1099 side, (4) running a ‘loan-out’ personal service corporation that gets hit with the §269A flat 21% trap, (5) missing the HSA triple advantage, (6) treating PSLF as folklore instead of a real subsidy worth $200K+, and (7) failing to manage AMT exposure in years with large incentive comp or stock from a hospital affiliate.

The framework that follows assumes a typical attending: $400K-$900K total compensation, some W-2, some 1099, married filing jointly, two kids, in a high-tax state. Adjust the moves for your situation but the architecture holds.

One thing to set straight before we go further: medicine is generally a Specified Service Trade or Business (SSTB) under IRC §199A(d)(2). That matters because the §199A 20% deduction phases out for SSTB owners with taxable income above $241,950 single / $483,900 MFJ (2026 estimated, indexed from the 2025 figures of $241,950 / $483,900). Most attendings are above the phase-out. But there are slivers of medical income that aren’t SSTB — medical device royalties, medical real estate, certain ancillary services — and those keep §199A intact. We’ll get into that.

The W-2 plus 1099 split — why the hybrid model wins

Most attending physicians I work with end up in some version of a hybrid: employed at a hospital or large group (W-2), plus a 1099 side. The 1099 might be telemedicine through a platform like Teladoc or Amwell, expert witness work, locum tenens shifts, medical directorship, advisory boards, lectures, or a small private practice on top of the day job.

The hybrid model creates three planning advantages that pure W-2 doctors don’t have.

First, the 1099 income runs through Schedule C (or better, an S-corp), which means ordinary business deductions: home office, vehicle (mileage or actual), continuing medical education, malpractice tail insurance, professional dues, journal subscriptions, computer, phone, and a meaningful share of mortgage interest and utilities allocated to the home office under Form 8829. A telemedicine doctor who spends 200 square feet of a 2,000 square foot home on patient calls allocates 10% of utilities and mortgage interest to the business. On a $4,000/month mortgage payment with $30,000 of utilities, internet, and homeowner’s insurance annually, that’s $3,000 of deductions just from the home office. Plus another $2,000-$4,000 from vehicle expenses if patient-related driving exists.

Second, the 1099 income lets you fund a solo 401(k) or SEP IRA on top of the hospital 401(k). For 2025, the 401(k) employee deferral limit is $23,500 (with $7,500 catch-up at age 50+), and the total 415(c) defined contribution limit is $70,000 ($77,500 with catch-up). The hospital 401(k) eats the employee deferral. But the solo 401(k) on the 1099 side can soak up profit-sharing contributions up to $70,000 of the 415(c) limit minus what was contributed at the hospital — actually, employee deferrals are aggregated across plans but employer contributions are not. So a doctor maxing $23,500 at the hospital can put $46,500 of profit-sharing into the solo 401(k) on the 1099 side if the 1099 net earnings support it (you need roughly $186,000 of net SE income to fully fund the $46,500 employer side at 25%).

Third, the 1099 income lets you stack a cash balance plan, which is where the real money lives. We’ll devote an entire section to that.

But there’s a wrinkle. The 1099 income is medical, so it’s SSTB under §199A. Above the threshold, no §199A deduction on the 1099 income. That part stings.

The S-corp election. Once 1099 net income clears roughly $50,000-$75,000, the S-corp election starts paying. The doctor forms an LLC, elects S-corp tax treatment via Form 2553, pays themselves a reasonable W-2 salary out of the LLC, and takes the rest as K-1 distributions. The K-1 distribution piece escapes the 15.3% self-employment tax (capped at the Social Security wage base for SS, uncapped for Medicare). On $200K of 1099 net income, splitting $130K salary / $70K distribution saves roughly $2,000-$2,700 in Medicare tax annually. Modest, but real. The bigger benefit of S-corp election is the accountable plan it enables for CE, travel, and home office reimbursements — clean reimbursements not subject to the 2% AGI miscellaneous deduction haircut that was eliminated by TCJA anyway.

Reasonable compensation matters. BLS OES median wages by physician specialty are public. For 2024 the median was roughly $239K for primary care, $300K-$400K for specialists, $400K-$600K for surgical subspecialties. The IRS expects the W-2 portion of S-corp comp to bear a reasonable relationship to these benchmarks. Paying yourself $50K W-2 out of an S-corp generating $300K of pediatric income invites a reasonable compensation challenge under the doctrine articulated in Watson v. Commissioner, 668 F.3d 1008 (8th Cir. 2012). Be defensible: 60-70% of net to W-2 is a safe starting point, with documentation supporting the rest as return on the practice.

What about pure W-2 doctors? The W-2 employee has fewer levers. The hospital 401(k) deferral, the HSA if the health plan is HDHP-compatible, a backdoor Roth, and tax-loss harvesting in the taxable account. That’s about it for the comp side. Most of the use for a pure W-2 doctor sits outside the comp — real estate, charitable bunching, asset location across taxable/tax-deferred/tax-free buckets, AMT management in years with restricted stock vesting. We’ll cover those later.

A surprising line: in our practice, the highest-net-worth physicians we see aren’t the ones with the highest salaries. They’re the ones who built a 1099 side hustle that funded a cash balance plan from year three onward. Twenty years of $200K-$300K annual pre-tax contributions to a CB plan compounds to $8M-$15M. That’s the real lever.

The cash balance plan plus 401(k) profit-sharing stack — $300K+ pre-tax

This is the single highest-impact strategy for high-earning physicians with self-employment income. Pre-tax contributions of $250,000-$350,000 a year. We’ve set up plans pushing $400K for older specialists.

How it works. A cash balance plan is a hybrid defined benefit pension. The participant has a hypothetical ‘account balance’ that grows by employer contributions (the ‘pay credit’) plus an interest credit (typically 4-5% tied to a published index). At retirement or termination, the participant takes the account balance as a lump sum or annuity. From the IRS perspective, it’s a defined benefit plan governed by IRC §415(b) with maximum benefit limit of $280,000 of annual annuity for 2025 (projected $290,000 for 2026).

The actuarial side. The contribution required to fund the §415(b) max benefit depends on the participant’s age, expected retirement age, and the plan’s interest credit. A 55-year-old physician targeting retirement at 65 can fund roughly $250,000-$300,000 annually. A 60-year-old can fund $300,000-$400,000. A 45-year-old maybe $130,000-$180,000. The actuary runs the numbers and certifies the contribution.

Stack with 401(k) profit-sharing. The cash balance plan sits on top of a separate 401(k) profit-sharing plan. Combined limits under IRC §404 and the deduction rules: the 401(k) side carries the $70,000 415(c) limit (or $77,500 with catch-up at 50+). The cash balance plan carries the actuarially determined contribution.

Combined 2026 limits (projected) for a 55-year-old solo physician with sufficient self-employment income: – 401(k) employee deferral: $23,500 – 401(k) employer profit-sharing: $46,500 (to reach 415(c) limit) – Cash balance contribution: $250,000 – Total: $320,000 pre-tax At a 45% combined federal+state marginal rate, $320,000 of pre-tax contributions = $144,000 of current-year tax savings. Real dollars.

The catch — you need the cash flow. The contribution is mandatory once the plan is in place (cash balance plans require annual minimum contributions under IRC §430). Pre-fund only when 1099 income is reliable. Doctors with $50K of 1099 income shouldn’t set up a $250K cash balance plan.

The 1099 income required to support the full stack. Cash balance plus 401(k) profit-sharing eats a meaningful chunk of net SE income. Rule of thumb: net SE income must be at least 2x to 3x the targeted cash balance contribution. So funding $250K of cash balance plus $46.5K of 401(k) profit-sharing requires $500K-$750K of net SE income. The 1099 telemedicine doctor making $80K isn’t a cash balance candidate yet. The locum tenens specialist clearing $400K is.

Coverage rules and non-discrimination. IRC §401(a)(26) requires defined benefit plans to cover at least 40% of employees (or 2 employees, whichever is less). For a solo doctor with no employees, the plan covers one participant and satisfies the rule trivially. Add a spouse on payroll and you have two participants. Add a non-spouse W-2 employee and you must include them or fail §401(a)(26).

This is the issue when a small private practice with a medical assistant or front-desk staff wants a cash balance plan. The plan must offer benefits to the staff. Typically structured with a small pay credit for staff (1-3% of compensation) and a large pay credit for the physician-owner. The staff benefit is the cost of the plan; the physician benefit is the prize. Cross-tested plan designs let this work as long as benefits are actuarially balanced under IRC §401(a)(4).

Plan administration costs. A cash balance plan requires an actuary, a third-party administrator, and a recordkeeper. Annual costs typically $4,000-$10,000 for a solo plan, $8,000-$20,000 for a plan with staff. The cost is dwarfed by the tax savings.

Exit options. At retirement, the cash balance is typically rolled into the participant’s IRA. Lifetime accumulated tax deferral. Then RMDs at age 73 (under SECURE 2.0). For long-term planners, the cash balance plan is a deferred Roth conversion candidate — convert portions of the rollover IRA to Roth in low-income post-retirement years.

We’ve designed cash balance plans for doctors that fund $3M-$5M over 10 years pre-tax. The same comp at 45% combined marginal would have shipped $1.4M-$2.3M of tax to government. The plan is the most efficient legal tax shelter still available.

The §199A SSTB phase-out and what survives the threshold

Section 199A allows a 20% deduction on Qualified Business Income (QBI) for pass-through entities. The deduction is worth up to 7.4 percentage points of effective federal rate (20% × 37% = 7.4 points). For a physician with $400K of QBI, the deduction would be $80K, saving $30K of federal tax at the 37% bracket. Huge if it applies.

But §199A has a SSTB carve-out. Specified Service Trades or Businesses are excluded above the income threshold. Medicine is explicitly listed as SSTB under IRC §199A(d)(2)(A). So is law, accounting, consulting, financial services, performing arts, athletics, and investment management. The carve-out exists because Congress didn’t want service professionals — including doctors — to get the 20% deduction.

The income threshold. For 2026 (projected from 2025 figures with COLA), the SSTB threshold is: – Single: phase-out range $241,950 to $291,950 (full phase-out at $291,950) – MFJ: phase-out range $483,900 to $583,900 (full phase-out at $583,900) Above the top of the phase-out, the SSTB §199A deduction is zero. In the phase-out range, the deduction is partially reduced.

Most attending physicians blow through the upper threshold immediately. $500K of W-2 plus $100K of 1099 puts a single attending well above $291,950. The §199A deduction on the medical income is fully phased out.

So we focus on the non-SSTB income streams that survive.

Survival category 1: Medical real estate. A physician who owns the building where the practice operates and rents it back to the practice has rental income that’s NOT SSTB. Buildings and real estate are not specified service businesses. The rental income qualifies for §199A as long as the activity rises to the level of a §162 trade or business — which generally requires more than a single triple-net lease. Multiple properties, active management, or qualification under the 250-hour rental real estate safe harbor under Rev. Proc. 2019-38 helps. Cost: setting up the right entity structure (typically a separate LLC owning the building, with the practice paying rent at arm’s length).

Survival category 2: Ancillary services. A diagnostic imaging center, a sleep lab, a physical therapy operation, or a medical device sales business that’s separately operated may not be SSTB if it doesn’t itself involve the practice of medicine. The line is fuzzy. A radiologist who reads the films at an imaging center IS practicing medicine. The imaging center business that owns the equipment and bills for technical services may not be. Get a tax opinion before relying on the carve-out — the IRS scrutinizes these.

Survival category 3: Medical device royalties or IP licensing. A physician-inventor who receives royalties on a patent generally has non-SSTB income (the IP licensing isn’t a service business per se). Royalties are usually reported on Schedule E and can qualify for §199A if the activity rises to §162 trade or business level.

Survival category 4: Medical writing, education, and content. Authoring a book, producing CME content, running a paid educational platform — these can be non-SSTB if they don’t involve providing direct patient care or medical services. A doctor who runs a medical education company that creates online courses for other doctors may have non-SSTB income.

Survival category 5: Coaching, consulting outside the SSTB line. The line is fuzzy and the IRS pushes back. ‘Consulting’ is itself an SSTB. But operating a business that, say, helps medical practices with their accounting (a non-SSTB ancillary service) is different from consulting on medical decisions.

The reality: for 99% of attending physicians, §199A is unavailable on their primary income. Stop chasing it on the W-2 / 1099 split. The hours you’d spend trying to wedge a §199A claim are better spent on cash balance plan funding, HSA contributions, charitable bunching, and asset location.

If you genuinely have real estate, IP, or non-SSTB ancillary income, then the §199A planning gets real. Map the income streams, structure separate entities, document the trade or business under §162, and claim the deduction on Form 8995-A. Rev. Proc. 2024-40 updates inflation-adjusted thresholds annually.

Loss issue. If a doctor has a separate non-SSTB business that’s losing money (say, the real estate is in start-up phase with depreciation losses), the loss reduces QBI from other sources. Could even reduce QBI below zero, generating a §199A loss carryforward under IRC §199A(c)(2).

The §269A personal service corporation trap — why doctors need S-corps, not C-corps

Here’s a mistake that catches doctors who try to be clever. A physician forms a C corporation, has the hospital or group pay the C-corp instead of the doctor, and tries to take a low salary out of the C-corp while leaving income trapped inside at lower corporate rates. This is the classic ‘loan-out’ structure that works in entertainment and athletics — and gets crushed for doctors.

IRC §269A targets exactly this maneuver. When a personal service corporation (PSC) is formed to avoid or evade federal income tax, the IRS can reallocate income, deductions, credits, and other items between the PSC and its employee-owners to reflect the true tax picture. Worse — under IRC §11(b)(2), qualified PSCs are taxed at a flat 21% corporate rate with no graduated brackets (this was 35% pre-TCJA).

Definition of qualified PSC. A corporation is a qualified personal service corporation if (1) substantially all activities involve the performance of services in health, law, engineering, architecture, accounting, actuarial science, performing arts, or consulting, AND (2) substantially all stock is owned (directly or indirectly) by employees performing those services, retired employees who performed them, their estates, or persons who acquired the stock by reason of an employee’s death.

A solo physician C-corp that the doctor owns and works through is the textbook qualified PSC. Flat 21% on income retained in the C-corp.

What goes wrong. Doctor forms a C-corp thinking ‘I’ll pay myself $200K and keep $300K in the corp at 21%, paying less than my 37% personal rate.’ Two problems: (1) the §269A reallocation can shift the retained income back to the doctor at their personal rate, and (2) even if reallocation doesn’t apply, the $300K in the C-corp eventually exits as dividends (taxed at 20% qualified dividend rate plus 3.8% NIIT plus state) or as compensation (taxed at the doctor’s marginal rate plus payroll taxes). The double-tax economics on the dividend exit usually destroy any benefit from the 21% corporate rate.

Double tax math: $300K in C-corp pays $63K corporate tax (21%), leaving $237K. Distributed as dividend, taxed at 20% federal + 3.8% NIIT + 13.3% California state = 37.1% on the $237K = $88K of personal tax. Total tax: $63K + $88K = $151K on the original $300K. Effective rate: 50.3%. Compared to S-corp pass-through where the same $300K is taxed once at 37% federal + 13.3% state + 3.8% NIIT (on certain components) = roughly 45-48% combined.

Conclusion: for physicians, the C-corp PSC is almost always worse than an S-corp pass-through. Don’t fall for the 21% corporate rate marketing.

When does a doctor benefit from a C-corp? Rare cases: – Doctor plans to sell the corporate stock for QSBS treatment under IRC §1202 (excludes up to $10M of gain). But §1202 has specific requirements that PSCs often fail. – Doctor wants to retain massive earnings to fund a major acquisition (rare for solo physicians). – Doctor wants exotic benefit plans only available to C-corps (medical reimbursement plans under §105, for example — though Section 105 HRA plans now have alternatives via S-corps too). For 99% of physicians, S-corp is the right answer.

S-corp election. File Form 2553 within 2 months and 15 days of the start of the tax year you want the election effective (or get late election relief under Rev. Proc. 2013-30). The election converts the LLC’s tax treatment from default partnership/disregarded to S-corp. Reasonable comp + K-1 distribution structure follows.

Reasonable comp benchmark. We covered this. BLS OES medians by specialty are the starting point. The IRS uses a multi-factor test: training, responsibilities, time devoted, compensation paid for similar services by similar businesses, dividends paid relative to compensation, payments to non-shareholder employees, and the formality of the corporation. Document everything. Board minutes setting compensation, internal compensation studies, and Salary.com / BLS benchmarks all support the figure.

Cautionary tale. Watson v. Commissioner (8th Cir. 2012) involved a CPA paying himself $24K of W-2 out of an accounting practice generating $200K+ of net income. The Tax Court reallocated $67K of distributions to W-2, assessing additional FICA. The case set the standard: reasonable comp must reflect what an outside professional with comparable skills, experience, and responsibilities would earn. For physicians, the relevant benchmark is BLS specialty median or industry surveys.

PSLF, REPAYE, and the resident/early-attending playbook

Most physicians finish residency with $200K-$400K of student debt. Federal direct loans at 6-8% interest rates. Public Service Loan Forgiveness (PSLF) can wipe out the balance after 120 qualifying monthly payments while employed by a 501(c)(3) hospital or government employer. Real money.

Eligibility. PSLF requires (1) federal direct loans (or consolidation to direct), (2) qualifying employer (501(c)(3), government, AmeriCorps, Peace Corps), (3) full-time employment (averaging 30+ hours/week), (4) 120 qualifying monthly payments while on an income-driven repayment (IDR) plan, and (5) certification of employment annually using the PSLF Employer Certification Form. Most academic hospitals, large nonprofit hospital systems (Kaiser, Cleveland Clinic, Mayo, etc.), and VA hospitals qualify. Private practice does not.

The income-driven repayment plans. Current options as of 2025-2026 — the field shifted in 2024-2025 with court actions affecting SAVE plan, so we’ll describe what’s currently operational: – PAYE: payments capped at 10% of discretionary income, forgiveness after 20 years. – REPAYE / SAVE (transition issues — check current status): historically 5-10% of discretionary income with interest subsidy. – IBR: 10-15% of discretionary income, forgiveness after 20-25 years. – ICR: 20% of discretionary income.

For PSLF, the payment plan choice matters. Lower payments while in residency = more forgiveness at PSLF.

The classic resident PSLF strategy. Resident earns $65K-$75K. IDR payment is calculated on prior year AGI, which during intern year may be even lower (medical student income from the prior year). First-year payments often $0-$300/month. Three years of residency × 12 months = 36 qualifying payments before becoming an attending. If the resident then takes a 501(c)(3) attending position for 7 more years (84 months), they hit 120 qualifying payments and the remaining balance is forgiven.

Forgiven amount. Resident plus early-attending payments on IDR might total $40K-$80K over 10 years. If the loan balance was $300K with 7% interest, the unpaid balance after 10 years could be $200K-$300K. That’s the forgiveness.

Tax treatment of PSLF forgiveness. IRC §108(f)(1) excludes PSLF forgiveness from gross income for federal tax purposes. So the forgiven $200K-$300K is tax-free federally. Some states tax it (check state conformity).

The marriage and filing status problem. PSLF payment calculations use AGI. Married filing jointly aggregates spouse income. A resident married to a high-earning spouse (engineer, attorney) may face IDR payments based on combined household AGI — much higher payments, less forgiveness benefit. Married Filing Separately (MFS) can fix this in some IDR plans (REPAYE always uses combined income; PAYE and IBR allow MFS to exclude spouse income in some scenarios). MFS has its own tax cost — generally a few thousand dollars more in combined tax compared to MFJ. Run the numbers.

Backdoor Roth considerations during residency. Residents can do backdoor Roth contributions (contribute $7,000 to nondeductible traditional IRA, convert to Roth — assuming no other traditional IRA balances triggering pro-rata under IRC §408(d)). Building a Roth balance during low-income years is one of the cleanest moves a resident can make. By the time of attending years (when income is too high for direct Roth), the Roth is funded and growing tax-free.

Loan refinancing decision. If you’re confident you won’t qualify for PSLF (private practice, non-501(c)(3) hospital), refinance federal loans to a private lender for lower interest rate. Current refinance rates 4-6% versus federal direct rates 6-8%. Saves $30K-$80K of interest over a typical 10-year repayment. But refinancing kills PSLF eligibility — federal loans become private and don’t qualify. Don’t refinance until you’re sure about the employment trajectory.

The wrinkle: hybrid moonlighting during residency. Residents who moonlight (1099 income from urgent care or telemedicine) face IDR calculation complexity. The moonlighting income raises AGI, which raises IDR payments. Some residents structure moonlighting through an S-corp to reduce SE tax exposure, though margins are thin at lower income levels.

REPAYE / SAVE legal status. As of late 2025, the SAVE plan is in legal limbo from court challenges. Borrowers should monitor the Department of Education’s announcements and consider whether to switch to PAYE or IBR. The structural PSLF benefit hasn’t been challenged — just the specific IDR plan terms.

HSA triple advantage and high-deductible health plan strategy

Doctors love an HSA in concept but most don’t actually fund one. The HSA is the only account with a triple tax benefit: contribution deductible, growth tax-free, distribution tax-free for qualified medical expenses. No other account does all three.

Eligibility. To contribute to an HSA, the doctor must be enrolled in a High Deductible Health Plan (HDHP). For 2025, HDHP means deductible at least $1,650 single / $3,300 family, with out-of-pocket maximum no more than $8,300 single / $16,600 family. Many hospital benefit plans offer an HDHP option alongside traditional PPO plans.

Contribution limits 2025: $4,300 single / $8,550 family. 2026 (projected): $4,400 single / $8,750 family. Plus $1,000 catch-up at age 55+.

IRC §223 governs HSAs. The contribution is above-the-line deductible (reduces AGI, not just taxable income). For a physician in the 37% federal + 13.3% California bracket, a $8,550 family contribution saves roughly $4,300 in tax. The HSA balance grows tax-free. Distributions for qualified medical expenses (defined broadly under IRC §213(d) — doctor visits, prescriptions, dental, vision, certain insurance premiums, long-term care) are tax-free.

The optimal HSA strategy for doctors with sufficient cash flow: don’t spend the HSA balance. Pay current medical expenses out of pocket. Save receipts (current medical expenses can be reimbursed from the HSA at any time in the future — no time limit). Invest the HSA balance in stocks/ETFs. Let it compound for 20-30 years. Then in retirement, you have a substantial tax-free medical fund AND the ability to reimburse decades of historical medical expenses tax-free.

Hypothetical: doctor contributes $8,500/year to HSA for 30 years (ages 35 to 65). Invests at 7%/year. Final balance: $865,000. All available for medical expenses (or reimbursement of historical expenses) tax-free. Effectively a third retirement bucket alongside the 401(k) and Roth.

What if you don’t need the HSA balance for medical expenses? After age 65, HSA distributions for non-medical purposes are taxed as ordinary income (no penalty). So the HSA becomes a traditional-IRA-equivalent at 65+. Before 65, non-medical distributions face 20% penalty plus ordinary income tax — avoid.

HSA mistakes to avoid: – Spending the balance currently instead of investing. The triple benefit only works when the balance compounds. – Not coordinating with FSA. You can’t have an HSA and a general-purpose FSA simultaneously (one of them disqualifies the HSA). – Failing to invest the HSA. Many HSAs default to cash. Move it to a brokerage HSA (Fidelity HSA is the cleanest) and invest. – Forgetting the spouse’s HSA. If both spouses are HDHP-eligible, each can have an HSA up to the family limit (combined). – Missing the catch-up. Age 55+ allows $1,000 additional per year. Both spouses 55+ can contribute catch-ups in their own HSAs.

Coverage gap issue. Going on Medicare at age 65 disqualifies HSA contributions (Medicare isn’t an HDHP). So contributions must stop. Plan for that — fund heavily in the years leading up to Medicare.

For physicians who already have a hospital high-deductible plan as a benefit option, the HSA is essentially free money. The hospital may even contribute to your HSA as part of the benefit package (some do $500-$2,000/year). Take it.

Backdoor Roth, mega backdoor Roth, and the pro-rata rule

Direct Roth IRA contributions phase out at $146,000-$161,000 single / $230,000-$240,000 MFJ for 2024 (slightly higher for 2025-2026). Every attending physician is above the phase-out. The direct Roth is unavailable.

The backdoor Roth. Contribute up to $7,000 ($8,000 at 50+) to a traditional IRA — nondeductible because of income limits — then convert to Roth. The conversion has no income limit. Build a Roth balance one year at a time.

Mechanics. (1) Open a traditional IRA. (2) Contribute nondeductible amount. (3) Wait a few days. (4) Convert to Roth IRA. (5) Report the contribution on Form 8606 Part I. (6) Report the conversion on Form 8606 Part II.

The pro-rata rule. The catch is IRC §408(d)(2): if you have any other pre-tax traditional IRA balance (including rollovers from 401(k)s), the conversion is partially taxable based on the ratio of pre-tax to total IRA assets. Example: $93K pre-tax IRA from a 401(k) rollover plus $7K new nondeductible contribution = $100K total, of which 93% is pre-tax. Converting $7K means 93% × $7K = $6,510 is taxable. Defeats the purpose.

Fix: get the pre-tax IRA out before the conversion. Roll the traditional IRA back into a current 401(k) or solo 401(k) (most 401(k) plans accept rollovers in). This ‘reverse rollover’ empties the IRA. Then the backdoor Roth is clean.

Mega backdoor Roth. For physicians with self-employment income and a solo 401(k) that allows after-tax contributions (not all do — check the plan document), the mega backdoor can move $30K-$50K+ into Roth annually. The mechanics: solo 401(k) accepts after-tax employee contributions up to the 415(c) limit minus other contributions. Those after-tax contributions are immediately converted in-plan to Roth, building Roth balance faster than the standard $7K backdoor.

Combining stacks for a high-earning physician with 1099 income: – Backdoor Roth IRA: $7,000 – Spousal Backdoor Roth IRA: $7,000 – Solo 401(k) Roth deferral: $23,500 (employee deferral can go Roth) – Solo 401(k) after-tax + in-plan conversion (mega backdoor): up to $46,500 (depending on 415(c) headroom) – Total Roth funding: up to $84,000/year Over 20 years compounding at 7%, that’s $3.4M of tax-free Roth balance. For a doctor in their early career, this is the foundation of post-retirement tax efficiency.

Roth conversion in low-income years. Sabbaticals, parental leave, gap years between jobs — these are conversion windows. Convert $50K-$200K from traditional IRA to Roth in a year with low ordinary income. Pay tax at the 12% or 22% bracket instead of the 37% bracket where the money would otherwise come out.

The 5-year rule. Roth conversions have a 5-year holding rule for penalty-free access to converted amounts (separate from the Roth IRA 5-year rule for tax-free earnings). Doctors converting close to retirement should plan around the 5-year clock if early access is needed.

State tax on conversions. California taxes Roth conversions as ordinary income. Consider timing conversions in residency moves — convert in a year you’re not California-resident if possible. For doctors who move from Massachusetts to Florida (no state income tax) before retirement, defer conversions until after the move to save state tax.

Charitable bunching, donor-advised funds, and AMT-aware giving

TCJA’s standard deduction roughly doubled ($14,600 single / $29,200 MFJ for 2024, projected $15,100 / $30,200 for 2026). The SALT cap at $10,000 (proposed expansions to $40,000 under various legislative discussions as of 2025) means most physicians can’t itemize meaningful state tax. So charitable contributions often don’t clear the standard deduction threshold in any given year, wasting the deduction value.

The fix: bunching. Combine 3-5 years of charitable giving into one year, then take the standard deduction in the off years.

Mechanics. Open a donor-advised fund (DAF) at Fidelity Charitable, Schwab Charitable, or Vanguard Charitable. Contribute $50,000-$200,000 of appreciated long-term securities in one year. Take the full deduction in that year (subject to AGI limits: 30% of AGI for appreciated securities, 60% for cash). Then make grants from the DAF to operating charities over the next 3-5 years.

Example: doctor making $700K MFJ wants to give $25,000/year to charity. Standard approach: $25K of giving + $10K SALT = $35K itemized. Standard deduction is $30,200. Marginal benefit of itemizing: $4,800.

Bunched approach: in year 1, contribute $125,000 (5 years of giving) to DAF. Itemize: $125K + $10K SALT = $135K. Standard deduction: $30,200. Benefit of itemizing in year 1: $104,800 at 37% federal = $38,776 of additional federal tax savings versus standard deduction. Years 2-5: take standard deduction, give nothing personally but grant from the DAF.

Versus the unbunched approach: 5 years × $4,800 marginal benefit = $24,000 of total tax savings. Bunching saves an extra $14,776 over the 5-year period.

Appreciated securities versus cash. Always give appreciated long-term securities, not cash. Two benefits: (1) the full fair market value is deductible (assuming public stock), and (2) the unrealized capital gain is never taxed. A physician with $50K of cost basis in a stock now worth $100K can donate the stock and deduct $100K while avoiding the $50K of unrealized gain. Equivalent to a 23.8% tax savings (20% capital gains + 3.8% NIIT) on the gain plus the regular charitable deduction value.

Don’t donate cash if you have appreciated securities. Sell the cash equivalent positions (e.g., bonds) and use the cash for living expenses. Donate the appreciated stock.

AMT considerations. The Alternative Minimum Tax under IRC §55 can affect physicians with large state tax deductions, incentive stock options, or other preference items. After TCJA the AMT mostly applies to higher-income taxpayers with significant ISO exercises. Charitable contributions don’t create AMT preference items — they reduce both regular tax and AMT equally. So bunching doesn’t hurt AMT planning.

Muni bonds for AMT-impaired doctors. If you’re AMT-exposed, regular municipal bonds reduce regular tax but private activity bonds add back as AMT preference items. Choose ‘AMT-free’ muni funds for AMT-impacted years. Look at fund prospectuses for the AMT-preference percentage.

Charitable remainder trusts (CRT). For very large gifts ($500K+), a CRT can provide income to the donor for life or a term of years while ultimately benefiting charity. Useful for doctors with concentrated stock positions or appreciated real estate. The donor gets an immediate charitable deduction for the present value of the remainder interest, avoids capital gains on the contributed asset, and receives a stream of income.

Qualified Charitable Distributions (QCDs) after age 70.5. Direct IRA-to-charity transfers up to $108,000 in 2026 (projected, indexed from $105K in 2024) satisfy RMDs without including the distribution in income. Powerful tool for retired doctors with required distributions.

Medical malpractice insurance, accountable plans, and small deductions that compound

Medical malpractice premiums are deductible business expenses. For W-2 doctors, the hospital pays. For 1099 doctors, the doctor pays directly — and deducts on Schedule C or through the S-corp.

Specialty premium ranges (2024-2025 estimates): – Family medicine: $4K-$15K/year – Internal medicine: $5K-$18K/year – Surgery (general): $30K-$80K/year – OB/GYN: $50K-$200K+/year – Neurosurgery: $50K-$250K+/year in high-litigation states Malpractice tail coverage (extended reporting endorsement) covers claims reported after the doctor leaves a claims-made policy. Tail can cost 100-300% of the annual premium as a one-time payment. Fully deductible.

Accountable plan for S-corp doctors. IRC §62(c) and Treas. Reg. §1.62-2 establish accountable plan rules. Under an accountable plan, the S-corp reimburses the physician-employee for business expenses paid personally. The reimbursement is excluded from the employee’s W-2 income, and the corporation deducts the reimbursement.

Examples of accountable plan reimbursements: – Home office expenses (allocated portion of utilities, internet, insurance) – Vehicle expenses for business mileage – Continuing medical education travel and registration – Professional dues and journal subscriptions – Phone and computer if used for business – Medical equipment used in private practice The reimbursement must be: (1) for a business expense, (2) substantiated within a reasonable time (typically 60 days), and (3) any excess advance returned. Document with receipts and a written expense report.

Why this matters: post-TCJA, unreimbursed employee business expenses are not deductible (the 2% AGI miscellaneous deduction was eliminated). So if the physician pays $5K of CME out of pocket as a W-2 employee, there’s no deduction. But if the physician is an S-corp owner-employee and the corporation reimburses $5K under an accountable plan, the corporation deducts $5K and the physician’s W-2 isn’t increased. Tax savings: $5K × ~45% combined marginal = $2,250.

Section 179 and bonus depreciation. Practice-owning physicians can immediately expense equipment purchases under IRC §179 (up to $1.16M for 2024, indexed up) or bonus depreciation under IRC §168(k) (60% for property placed in service in 2024, phasing down 20% per year — 40% in 2025, 20% in 2026, 0% in 2027 unless Congress extends).

Big-ticket medical equipment qualifies: ultrasound machines, EKG equipment, dental cone-beam CT, ophthalmology equipment, dermatology lasers, physical therapy equipment. New or used qualifies. Vehicles over 6,000 GVWR (heavy SUVs) get partial §179 / bonus depreciation.

Catch: §179 expense is limited to business income (can’t generate a loss). Bonus depreciation can generate a loss (subject to other loss limitation rules under §461(l) for excess business losses, capped at $610K single / $1.22M MFJ for 2024).

Locum tenens deductions. Physicians working as locum tenens (temporary 1099 contracts at hospitals across the country) have additional deductible expenses: travel between assignments, temporary lodging at assignments more than 50 miles from tax home, meals (50% deductible) while away, licensing fees for multiple states, credentialing fees, DEA registration fees. Track everything.

DEA registration ($888/year for 2024), state medical license fees ($300-$1,500/year per state), board certification recertification ($1,500-$3,000 per cycle), CME credits ($1,000-$5,000/year typical) — all deductible business expenses for 1099 docs.

State residency, domicile games, and the doctor who ‘moved to Florida’

Top federal rate is 37%. Top California rate is 13.3% (going to 14.4% with SDI uncap). Top New York rate is 10.9%. Florida, Texas, Nevada, Tennessee, Washington, Wyoming, South Dakota, Alaska, and New Hampshire have no state income tax (Tennessee and Washington tax interest/dividends only in some cases, but no wage tax).

For a physician at $700K of income, the state tax savings from moving from California to Florida is roughly $80K-$95K per year. Real money. Over a 20-year career, $1.6M-$1.9M of after-tax wealth difference.

The ‘domicile’ versus ‘residency’ distinction. Domicile is your permanent home — the place you intend to return to and where you have your closest ties. Residency is where you physically spent time during the tax year. A doctor can be a Florida domiciliary while spending months working in California — but California will tax the California-source income as a nonresident.

California’s aggressive nexus rules. California’s Franchise Tax Board uses a multi-factor test to determine domicile, including: where you spend the most time, where your family lives, where your driver’s license is, where you’re registered to vote, where you bank, where you have your primary doctor, where your kids go to school, where you receive mail. FTB Publication 1031 is the operative guide.

The classic mistake. Doctor ‘moves to Nevada’ but keeps the Bay Area house, keeps the kids in Marin schools, keeps the same primary care doctor, comes back every weekend. California considers this person a California domiciliary and taxes all worldwide income. Tax assessment, penalty, interest, and a long fight.

The right way to actually change domicile: – Sell or rent out the high-tax-state home – Move family with you (or be single) – Get new state driver’s license within 60 days of move – Register to vote in new state – File last partial-year resident return correctly with the high-tax state – File new state’s resident return going forward – Establish actual local ties: doctor, dentist, bank, gym, churches, social clubs – Document the move: moving company receipts, utility connection records, lease/purchase documents – Spend more days in the new state than in any other (and ideally less than 184 days in the high-tax state)

Income earned while physically in the high-tax state remains taxable by that state, regardless of domicile. So a Florida-domiciled doctor doing a 2-month locum in California pays California nonresident tax on the California-source income. Federal allows a credit for state tax paid to another state, so no double tax on a federal level.

Telemedicine sourcing rules. If a Florida-domiciled doctor sees California patients via telemedicine, where is the income sourced? Generally to the doctor’s location (Florida) unless the doctor is physically present in California. The licensing arrangement matters — the doctor must be licensed in the patient’s state. But income sourcing follows the provider, not the patient, in most state rules.

Practical advice: real moves, not paper moves. The IRS and state tax authorities have heard every story. They have data — credit card statements, EZ Pass records, social media check-ins. If you’re going to move for tax purposes, actually move.

Common doctor relocation paths: – California academic medicine → University of Florida or University of Texas system – New York or NJ → Florida private practice or Tennessee – Massachusetts → New Hampshire (only 35 minutes from Boston but no state income tax) – Oregon → Washington (right across the Columbia)

Watch the in-and-out tax. Some states have a ‘retroactive resident’ rule if you spent significant time during the year. California sometimes asserts residency if you’re in-state for more than 6 months out of 18 months. Spend time outside the high-tax state if you’ve moved out.

Form 8275 disclosure, aggressive positions, and the audit math

Some doctor tax strategies high income approaches walk close to the line. Reasonable comp on an S-corp, §199A claims on ancillary income, large home office deductions, classification of a moonlighting gig as 1099 vs W-2 — these are areas where the IRS and the doctor can disagree.

Form 8275 (Disclosure Statement) and Form 8275-R (Regulation Disclosure Statement) are used to disclose positions on a return that are contrary to specific guidance or that might be considered aggressive. Filing a Form 8275 disclosure does NOT prevent IRS challenge — it does eliminate the accuracy-related penalty under IRC §6662 (20% of the underpayment) if the position is adequately disclosed and has a reasonable basis (less than ‘more likely than not’ but more than frivolous).

When to file Form 8275. Doctor takes an aggressive §199A position claiming ancillary business income isn’t SSTB. The position is supported by reasonable analysis but might be challenged. Filing Form 8275 with the return disclosing the position protects against the 20% accuracy-related penalty if the IRS later challenges and wins.

When NOT to file Form 8275. Most ordinary tax positions don’t warrant disclosure. Routine §179 deductions, standard reasonable comp on S-corps within BLS benchmarks, ordinary business expense deductions — these are positions backed by clear law and don’t need disclosure.

Audit triggers for physicians. The IRS doesn’t publish formal triggers but patterns are visible: – Schedule C losses on a ‘side business’ that’s really a hobby (medical practice loss is rare; cosmetics, photography, racing-as-business are common physician triggers) – Large home office deductions relative to home size or business activity – Unreasonably low S-corp salary versus distributions – Round-number deductions ($5,000 of CME with no documentation) – Charitable deductions over 60% of AGI – Missing 1099s (the IRS computer matches 1099s to returns)

Statute of limitations. The IRS generally has 3 years to audit a return from the filing date. Substantial understatement of income (>25% of gross income omitted) extends to 6 years. Fraud has no statute of limitations.

Documentation discipline. Receipts, mileage logs, calendar records, board minutes for the S-corp, written compensation studies, separate bank accounts for business and personal. Doctors who get audited and lose generally lost because they couldn’t document, not because the position was wrong.

Practical audit defense: when the audit notice arrives, get representation. CPA or EA with audit experience. Don’t talk to the auditor directly without representation. The audit usually focuses on 2-3 issues, not the whole return. Settle the audit on terms that close the year.

Correspondence audits are by mail and target specific issues. Field audits are more involved and conducted in-person or at the CPA’s office. Office audits are at an IRS office. The intensity scales from correspondence to field. For physicians, most audits start as correspondence on a specific deduction (home office, charitable, business meals), then escalate if the auditor finds issues.

Putting it all together — a sample physician tax stack

Let’s tie this into a single concrete scenario. Sarah is 48, board-certified internal medicine. Married, two kids in college. $550K hospital W-2 (employed by 501(c)(3) hospital), plus $180K of 1099 income from teaching, expert witness work, and a small concierge practice. Husband is a software engineer at $250K W-2. They live in San Diego, California.

Pre-planning baseline: $980K combined gross income. Federal tax at marginal rates roughly $300K. California state tax $90K. FICA, Medicare, NIIT, additional Medicare $40K. Total tax burden: $430K. Effective rate: 44%.

The planning stack:

1. S-corp election on the 1099 income. Sarah forms Sarah Medical Services, LLC, elects S-corp. Net 1099 income $180K, pays herself $120K W-2 salary, $60K K-1 distribution. SE tax savings on the $60K distribution: ~$1,700/year. Plus accountable plan reimbursements for CME, home office, vehicle: $8K additional deductions. Tax savings: $3,600/year.

2. Cash balance plan plus solo 401(k) on the S-corp. Sarah’s age 48, S-corp income $180K. Cash balance contribution: $130K/year. Solo 401(k) employee deferral (Roth, going to a Roth 401(k) within solo plan): $23,500. Solo 401(k) profit-sharing: minimal (most was eaten by cash balance). Total pre-tax contributions: ~$155K. Tax savings at 45% combined marginal: $70K.

3. Hospital 401(k) max. Sarah maxes the hospital 401(k) at $23,500 employee deferral (using Roth at hospital, traditional at solo to balance tax buckets). Hospital match: assume 5% on $550K capped at $345K (compensation cap) = $17,250 employer contribution. No direct tax savings for the match but adds to retirement balance.

4. HSA contributions. Sarah and husband both eligible (family HDHP through hospital). Family HSA contribution: $8,550 + $1,000 catch-ups at 55+ when they qualify. Currently $8,550/year. Tax savings: $3,800.

5. Backdoor Roth for both spouses. $7,000 each. $14,000 total Roth funding. No current-year tax savings but future tax-free growth.

6. Charitable bunching. Annual giving target $20,000. Bunch 5 years into a DAF ($100K contribution in year 1) using appreciated Amazon stock from husband’s RSUs. Year 1 itemized deduction: $100K + $10K SALT = $110K versus $30K standard deduction. Marginal tax savings: $36K. Spread benefit: $7,200/year average across 5 years.

7. §529 contributions for college. Two kids, 18 and 16. College costs $80K/year each. Front-load the §529s in years before junior year (when assets get assessed for financial aid). California doesn’t offer a state deduction for §529 (one of the few states that doesn’t), but federal tax-free growth and tax-free qualified withdrawals still apply.

8. State residency stays California (kids in school, husband’s job). Not the time for a move.

Post-planning math: total pre-tax contributions $200K+, plus $20K HSA/Roth, plus $36K charitable in year 1. Reduced taxable income by roughly $240K in year 1. Federal tax savings at 35% marginal: $84K. State tax savings at 11% marginal: $26K. Total year-1 savings: $110K.

Effective rate goes from 44% to roughly 33%. Eleven percentage points back to Sarah and her family. Over 20 years of working this stack, the cumulative wealth differential is staggering — $2.5M-$4M of additional after-tax wealth compared to the unplanned baseline.

What’s missing from this stack: real estate. Sarah doesn’t own income property. Adding rental real estate with cost segregation studies and bonus depreciation could push another 3-5 points off the rate. But it adds complexity and requires capital.

What’s also missing: §199A. Sarah is fully phased out due to SSTB classification. No deduction available unless she develops genuinely non-SSTB income streams (medical writing, IP licensing, ancillary services).

The point is the playbook is repeatable. We run a version of this stack for 80% of the physicians we serve at The Reed Corporation tax strategy consulting. The specific numbers shift but the architecture is the same.

Frequently Asked Questions

I’m a 42-year-old anesthesiologist making $750K W-2 at a non-profit hospital plus $100K of 1099 from telemedicine. How do I cut my effective tax rate using doctor tax strategies high income tactics?

At $850K total income, you’re squarely in the doctor tax strategies high income target zone. Let me walk through a real plan for your situation.

First, the baseline. $750K W-2 plus $100K of 1099 puts you at $850K of gross income. Filing married jointly with a non-working spouse and assuming California residency: federal tax around $245K, California state $80K, FICA capped at the Social Security wage base ($176K × 6.2% = $11K), Medicare 1.45% on all W-2 = $11K, additional Medicare 0.9% on income over $250K MFJ = $5K, plus another $7K-$10K of NIIT and miscellaneous. Total tax: $360K-$370K. Effective rate: 43%. Marginal rate on the next dollar: 49-51%.

The target is to bring effective rate to 32-35%. That’s $70K-$95K of annual savings.

Step 1: S-corp election on the 1099 income.

Form an LLC, file Form 2553 electing S-corp tax treatment for the 1099 income. Pay yourself a reasonable W-2 salary out of the S-corp, take the rest as K-1 distributions. For anesthesiology, BLS OES median is roughly $400K, so the reasonable comp on $100K of net SE income should be in the $60K-$75K range with $25K-$40K as K-1 distribution.

The SE tax savings on the $30K K-1 distribution: $30K × 2.9% Medicare = $870 (plus 0.9% additional Medicare in the high-income bracket = $270 more). Total $1,140 annual SE tax savings. Modest.

But the S-corp enables an accountable plan for CME, home office, vehicle, professional dues. Accountable plan reimbursements: $5,000-$8,000 annually of legitimate business expenses reimbursed pre-tax through the S-corp. Tax savings at your 45% marginal: $2,250-$3,600.

Step 2: Cash balance plan plus solo 401(k) on the S-corp.

This is the biggest lever. At age 42, the IRS §415(b) cash balance limit funds roughly $130K-$180K of annual contribution. Combined with solo 401(k) profit-sharing of $25K-$45K depending on your hospital 401(k) deferrals, total annual pre-tax retirement contributions could be $155K-$220K.

But you need the cash flow to support this. Your $100K of 1099 net income before contributions isn’t enough to fund a $130K cash balance plan plus $25K solo 401(k). Net income would need to grow to support the full stack.

Realistic year-1 plan: cash balance of $50K-$60K (sized to what the 1099 income supports after S-corp salary), plus solo 401(k) profit-sharing of $15K-$20K. Total $65K-$80K of additional pre-tax contributions on top of your hospital 401(k).

Tax savings at 45% combined marginal: $30K-$36K per year.

As your 1099 income grows in future years, the cash balance contribution can grow to $130K+.

Step 3: Hospital 401(k) max.

Max the hospital 401(k) at $23,500 (2025/2026 limit). Choose pre-tax versus Roth based on bracket arbitrage. At 45% marginal, pre-tax is generally better (deduct at 45% now, pay at maybe 25-30% in retirement). Hospital match presumably already happening — confirm vesting schedule and don’t leave early.

For 2025: $23,500 pre-tax 401(k) at 45% marginal = $10,575 of current-year tax savings.

Step 4: HSA.

If the hospital offers an HDHP option, switch to it. Family HDHP HSA contribution for 2026: $8,750. Triple tax benefit. Don’t spend the balance currently — invest it in stocks within the HSA. Pay current medical expenses out of pocket. Save receipts.

Tax savings: $8,750 × 45% = $3,938 current year.

Step 5: Backdoor Roth IRAs.

You and your spouse each contribute $7,000 to nondeductible traditional IRA, convert to Roth. Confirm no other pre-tax IRA balances (pro-rata rule). If there are pre-tax IRA balances from a prior 401(k) rollover, roll them back into your current 401(k) to clear the pro-rata math.

No current-year deduction but $14K/year of Roth funding for tax-free growth.

Step 6: 401(k) profit-sharing via mega backdoor (if solo 401(k) allows after-tax contributions).

Not all solo 401(k) plans allow after-tax contributions. Fidelity’s prototype plan does not; some third-party providers (Ascensus, Empower) offer custom plans that do. If your plan allows it, the mega backdoor can move an additional $20K-$40K of Roth contributions annually.

No current-year tax savings but substantial future Roth growth.

Step 7: Charitable bunching with a donor-advised fund.

If you’re giving more than $10K/year to charity, consider bunching. 3-year bunch: contribute $45K to a DAF in year 1, take the standard deduction in years 2-3. Use appreciated stock (you presumably have some Amazon, Apple, or Tesla in your taxable account that’s appreciated). Donate the appreciated stock, deduct full FMV, avoid the capital gains entirely.

Federal tax savings on $45K charitable deduction at 35% (above the $626K top-bracket threshold for federal): $15,750. Plus avoiding $5K-$8K of capital gains tax on the appreciation that would have been realized.

Step 8: §529 contributions for kids.

Not California — California doesn’t offer state §529 deduction. But the federal tax-free growth is still useful. If you have kids, contribute up to the federal gift tax exclusion ($19K/year per donor per beneficiary as of 2025) or use the 5-year forward election to contribute $95K all at once.

No current-year tax deduction in California. But the long-term tax-free growth is worth it.

Step 9: State residency.

If your job allows, consider relocating. Anesthesiology is portable — many state hospital systems need anesthesiologists. Move to Nevada (no state income tax) or Texas (no state income tax) and save $80K-$95K of California state tax annually. Over 20 years, that’s $1.6M-$1.9M of additional wealth.

Not practical if family, schools, or other ties anchor you to California. But run the numbers.

Step 10: Asset location and tax-loss harvesting.

In your taxable brokerage account, hold tax-efficient assets (index funds, ETFs, muni bonds). Hold bond-heavy positions in tax-deferred accounts (401(k), IRA). Hold growth and small-cap in Roth accounts.

Tax-loss harvesting: in the taxable account, sell positions that are down, replace with similar (not ‘substantially identical’) positions to avoid wash sale rules. Realized losses offset future gains and up to $3K/year of ordinary income.

Putting it all together for year 1.

Deductions and contributions: – Cash balance plan: $55K – Solo 401(k) profit-sharing: $18K – Hospital 401(k) deferral: $23,500 – HSA: $8,750 – Backdoor Roth: $14K (no deduction) – Charitable bunching: $45K (3-year bunch) – S-corp salary efficiency: $1,100 SE tax savings – Accountable plan: $6K (passes through, not added to W-2)

Taxable income reduction in year 1: roughly $156K.

Federal tax savings at 35% marginal: $54,600. California state tax savings at 11% marginal: $17,160. FICA/Medicare savings: $1,400.

Total year-1 tax savings: $73,000.

Effective rate goes from 43% to roughly 35%. Eight percentage points.

Over 20 years of running this stack with annual cost-of-living adjustments: estimated cumulative tax savings around $1.8M-$2.4M, plus the compounding of those savings invested over the period.

For an anesthesiologist at $850K, the doctor tax strategies high income playbook delivers real results. The cash balance plan alone justifies the planning. Coordinate with a CPA who handles physician practices — the standard CPA who does W-2 returns often misses these moves.

What’s the §199A SSTB phase-out for doctors in 2026 and is there any way to claim the 20% deduction as a high-income physician?

The §199A Specified Service Trade or Business phase-out is one of the more frustrating provisions for physicians because the deduction looks great on paper but gets stripped away for almost everyone above attending-level income. Let me work through the mechanics and the legitimate workarounds under doctor tax strategies high income planning.

The statutory framework.

IRC §199A allows a 20% deduction on Qualified Business Income from pass-through entities (S-corps, partnerships, sole props, certain trusts). For non-SSTB businesses, the deduction is generally available subject to wage/UBIA-of-property limitations above the income threshold.

For SSTB businesses, the deduction phases out completely above the income threshold. SSTB is defined in IRC §199A(d)(2) and includes health, law, accounting, actuarial science, performing arts, consulting, athletics, financial services, brokerage services, investing, investment management, trading, dealing in securities or commodities, and any business whose principal asset is the reputation or skill of one or more employees.

Medicine is health. Anesthesiology, surgery, primary care, dermatology, radiology, psychiatry — all SSTB. The principal asset is the physician’s skill.

The 2026 thresholds (projected from 2025 figures with COLA adjustment under Rev. Proc. 2024-40): – Single: phase-in begins at $241,950, fully phased out at $291,950 – Head of household: same as single – Married filing jointly: phase-in begins at $483,900, fully phased out at $583,900 – Married filing separately: half the MFJ amounts

In the phase-in range, the deduction is partially reduced. Above the upper threshold, no deduction for SSTB owners.

How the phase-out math works (when in the range).

For SSTB in the phase-in range, the applicable percentage is calculated as: 1 – (excess taxable income / phase-in range). Excess taxable income is the amount over the lower threshold. Phase-in range is $50K for single, $100K for MFJ.

Example: MFJ taxpayer with $533,900 taxable income (midpoint of phase-in range). Excess over lower threshold: $50K. Phase-in range: $100K. Applicable percentage: 1 – (50/100) = 50%.

The deduction is limited to 50% of what it would otherwise be. Plus the W-2 wage and UBIA limitations also start to apply in the phase-in range.

For most high-income physicians, you’re above the upper threshold and the deduction is zero on SSTB income.

Legitimate workarounds.

Workaround 1: Reduce taxable income below the threshold.

For borderline cases, contributions to retirement accounts can drop taxable income below the SSTB phase-out. A doctor at $510K taxable income MFJ is in the phase-in range. Contributing $30K to a cash balance plan, plus $23.5K to a 401(k), plus $8.7K to an HSA could drop taxable income to $448K — below the $483,900 threshold. Suddenly the 20% §199A deduction is fully available on whatever non-SSTB QBI exists.

For most attending physicians, the income is so far above the threshold that retirement contributions alone don’t push below. But for younger doctors or part-time practices, this is real.

Workaround 2: Separate the non-SSTB income.

Not all income earned by a physician is SSTB. Genuinely non-SSTB streams include:

Medical real estate. A physician who owns the medical office building separate from the practice and rents to the practice has rental income. Real estate is not SSTB. The rental income may qualify for §199A if it rises to the level of an IRC §162 trade or business (typically requires more than one property, active management, or qualification under the 250-hour safe harbor of Rev. Proc. 2019-38).

Structure: separate LLC owns the building. Practice (S-corp) leases the building at arm’s-length rent. The real estate LLC reports rental income on Schedule E (if held individually) or on the LLC’s return. §199A claimed on the rental income.

Medical device royalties or IP licensing. If you’ve invented a medical device or patented a method, royalty income is generally not SSTB. The IP itself is the asset, not the physician’s ongoing service.

Ancillary services. A diagnostic imaging center, a sleep lab, a physical therapy practice, an ambulatory surgical center — these may or may not be SSTB depending on whether they’re treated as the practice of medicine or as a separate business. The IRS has issued guidance (Treas. Reg. §1.199A-5) on the ‘crack and pack’ approach: separating out genuinely non-medical operations into separate entities. The line is fuzzy and gets challenged.

Key factors that help a non-SSTB classification: – Separate entity with separate ownership (not just same doctor owning both) – Separate operations, separate employees, separate books – Genuinely non-medical services (administrative, technical, equipment leasing) – Reasonable allocations between the SSTB and non-SSTB entities

The ‘crack and pack’ carve-out. Treas. Reg. §1.199A-5(c)(2) addresses the situation where a non-SSTB business is owned by an SSTB business. If 80% or more of the non-SSTB’s gross receipts come from the related SSTB, the non-SSTB is treated as SSTB. So you can’t simply split a service practice into an SSTB entity and a non-SSTB entity if they’re tightly intertwined.

Medical writing, education, content. Authoring books, producing CME content, running a paid educational platform are typically not SSTB (these are intellectual property and content businesses, not direct medical services). A physician who runs an online CME platform creating courses for other physicians may have non-SSTB income.

Non-medical consulting (outside the SSTB definition). Difficult because ‘consulting’ is itself an SSTB. But consulting that’s clearly outside the field of expertise — like a doctor consulting on real estate investments — would be a different business that doesn’t trigger SSTB if structured separately.

Workaround 3: Spouse’s separate business.

If the spouse has a non-SSTB business (e.g., e-commerce store, software development, plumbing contractor, manufacturing), that business’s QBI is separately analyzed for §199A. The physician’s SSTB income doesn’t taint the spouse’s business income.

MFJ taxpayers’ overall taxable income still has to be below the SSTB threshold for the spouse’s non-SSTB business to fully avoid the wage/UBIA limitations. But the spouse’s QBI is preserved regardless of the physician’s SSTB status.

Workaround 4: Defer income to a low-income year.

If you anticipate a low-income year (sabbatical, parental leave, year between jobs), defer compensation or 1099 invoicing to that year. Below the SSTB threshold, the §199A deduction on whatever QBI exists is available.

Workaround 5: Charitable contributions to reduce taxable income.

Charitable contributions reduce taxable income (when itemized). Large charitable contributions in a year can drop taxable income below the SSTB threshold. Combined with retirement contributions and other deductions, the threshold becomes achievable for moderate-income physicians.

What the deduction is worth when available.

For a physician with $100K of non-SSTB QBI (say, from rental real estate or medical IP): – §199A deduction: 20% × $100K = $20K – Federal tax savings at 32% marginal: $6,400 – Modest but real for borderline cases.

What NOT to do.

Don’t try to recharacterize medical income as non-SSTB through aggressive entity gymnastics. The IRS scrutinizes these claims. Treas. Reg. §1.199A-5 forecloses many of the obvious tricks. A doctor who simply renames his medical practice ‘Medical Administration Services LLC’ and claims §199A is going to lose.

Get a tax opinion before relying on §199A for any non-SSTB claim. The deduction sounds great but the audit risk on aggressive positions is high.

Forms and reporting.

Form 8995-A is the §199A computation for taxpayers with income above the threshold or with SSTB income. Form 8995 is the simplified version for taxpayers below the threshold. Schedule B of Form 8995-A handles the SSTB phase-out math.

The practical reality for most attending physicians: §199A on medical income is not available. The phase-out is total above $583,900 MFJ. Stop chasing it on the primary income. Focus on the legitimate non-SSTB streams — real estate, IP, ancillary businesses — if they genuinely exist. Otherwise, build the rest of the doctor tax strategies high income playbook (cash balance plans, S-corp efficiency, HSA, charitable bunching, state residency) and accept that §199A isn’t part of your stack.

Should I incorporate my private practice as a C-corp to take advantage of the 21% corporate tax rate, or stay with my S-corp?

Almost never the C-corp. The 21% corporate rate looks great in isolation, but the double-tax economics destroy any advantage for physician practices. Let me walk through the math and the §269A trap that catches doctors who try this.

The surface-level appeal.

The TCJA cut the corporate income tax rate to a flat 21% from the prior graduated structure topping at 35%. For physicians in the 37% personal marginal bracket plus state tax plus the 3.8% NIIT, the 21% C-corp rate sounds amazing.

The pitch goes: form a C-corp for the practice, pay yourself a reasonable salary, leave the rest of the income inside the corporation taxed at 21%. Skip the 37% personal rate. Save 16 percentage points.

The pitch is wrong for physicians for two reasons.

Reason 1: The §269A Personal Service Corporation trap.

IRC §269A targets corporations formed by individuals to provide personal services to a single client (typically the doctor’s employer hospital or a primary contracting entity). When the corporation exists principally for tax avoidance and substantially all activities involve personal services, the IRS can reallocate income between the corporation and its owner-employee.

More important: IRC §11(b)(2) imposes a flat 21% tax rate on ‘qualified personal service corporations’ — corporations where (1) substantially all activities involve services in health, law, engineering, architecture, accounting, actuarial science, performing arts, or consulting, AND (2) substantially all stock is owned by employees performing those services or related parties.

A solo physician C-corp meets both conditions. It’s a qualified PSC. Flat 21% on retained earnings (not graduated brackets — the 21% rate is the only rate, applied from the first dollar).

This is the same 21% as the regular C-corp rate, so no immediate disadvantage. But it removes any benefit from graduated brackets for small earnings.

Reason 2: The double-tax exit.

C-corp profits get taxed twice: once at the corporate level (21%), once when distributed as dividends or wages.

Dividend distribution math: $100K of pre-tax C-corp income. 21% corporate tax = $21K. Leaves $79K available for distribution. Distributed as qualified dividend to the shareholder-physician. Taxed at 20% federal qualified dividend rate + 3.8% NIIT + 13.3% California state = 37.1%. Tax on dividend: $79K × 37.1% = $29.3K.

Total tax on the $100K of corporate income: $21K + $29.3K = $50.3K. Effective rate: 50.3%.

Compare to S-corp pass-through: $100K of pass-through income. Taxed once at the physician’s marginal rate. 37% federal + 13.3% state + 3.8% NIIT (on K-1 distributions, depending on material participation) = roughly 45-50%. Slightly better than the C-corp double tax in California, but the gap is real in lower-tax states.

Wage distribution math: same $100K of pre-tax C-corp income. Instead of dividend, paid out as additional W-2 salary. Corporate tax is zero (wages are deductible). FICA/Medicare on the wages: 7.65% employer + 7.65% employee = 15.3% combined (capped at Social Security wage base for SS portion, uncapped for Medicare). Plus federal/state income tax at marginal rate.

Wage exit total tax: 0% corporate + 15.3% payroll + 37% federal income + 13.3% state = 65.6% on the wage portion. Actually worse than dividend exit because of payroll tax.

Neither exit beats the S-corp.

When does the C-corp work?

In very specific scenarios:

Scenario 1: Long-term retained earnings strategy where the C-corp accumulates capital to fund a major acquisition or strategic investment. Tax deferral on retained earnings can have value if the eventual exit is via QSBS gain exclusion (IRC §1202).

IRC §1202 allows up to $10M of capital gain exclusion on the sale of qualified small business stock held more than 5 years. But qualified small business doesn’t include personal service businesses where the principal asset is reputation or skill of one or more employees — and physician practices typically don’t qualify. The QSBS strategy is mostly available to tech and manufacturing C-corps, not medical practices.

Scenario 2: Specialized fringe benefits. Some benefits are only available to C-corp employees, not S-corp owner-employees (who are subject to the 2% S-corp shareholder rule limiting tax-free benefits). Examples: medical reimbursement plans under IRC §105 (largely obsolete after ACA), group term life insurance over $50K, certain disability insurance arrangements.

For most physicians, these niche benefits don’t justify the C-corp tax cost.

Scenario 3: Multi-physician practice with retained earnings for capital expenses (new building, expensive equipment). The 21% corporate rate on retained earnings might support reinvestment for a few years while the practice grows. But this usually still works out worse than S-corp due to the eventual double tax.

The practical answer for solo physicians.

S-corp is the right answer. Form 2553 election. Reasonable W-2 compensation per BLS specialty median. K-1 distributions for the rest. Accountable plan for business expense reimbursements. Solo 401(k) plus cash balance plan on the S-corp side. This stack delivers the best after-tax economics.

The S-corp passes income through to the shareholder-physician’s personal return on Schedule E. Income is taxed once at the physician’s marginal rate. No double tax. SE tax savings on the K-1 distribution portion (vs. paying all as W-2). Access to qualified retirement plans through the S-corp.

Form 1120-S is the S-corp return. Schedule K-1 reports the income to the physician. Reasonable comp goes on the physician’s W-2 (Form W-2) and the S-corp deducts as payroll expense. K-1 distribution shows on Schedule E.

State considerations.

Some states impose an entity-level tax on S-corps (California has the 1.5% S-corp franchise tax, minimum $800). Texas has the franchise tax (margin tax). New York City has the General Corporation Tax on S-corps. These state-level entity taxes reduce the S-corp advantage somewhat but don’t reverse the federal calculus.

State pass-through entity tax (PTET) elections. Many states have implemented PTET elections that allow S-corps and partnerships to pay state income tax at the entity level, providing a federal deduction (workaround for the $10K SALT cap on individual returns). California, New York, New Jersey, Connecticut, and 30+ other states offer PTET. For high-income physician S-corps, the PTET election can save several thousand dollars per year of federal tax by converting non-deductible state income tax into deductible entity-level tax.

Final recommendation.

Keep the S-corp. Don’t switch to C-corp. If you’re already a C-corp, evaluate the conversion to S-corp (which has its own gotchas — built-in gains tax under IRC §1374, LIFO recapture, etc., but generally workable for service businesses with limited inventory).

For doctor tax strategies high income planning, the S-corp wins almost universally. The 21% corporate rate marketing is a trap. Run the math on your specific situation but expect the S-corp to come out 5-15 percentage points ahead in effective rate.

Get a tax advisor who specifically handles physician practices. Generic CPAs sometimes recommend C-corps based on the 21% headline rate without modeling the double-tax exit. Don’t fall for it.

How does PSLF work for physicians in residency and early attending years, and what’s the tax impact when the loans are forgiven?

Public Service Loan Forgiveness is one of the highest-value doctor tax strategies high income tactics for residents and early-career attendings. Done right, it can wipe out $200K-$400K of student debt tax-free. Done wrong, you miss the window and pay the loans in full. Let me walk through the mechanics carefully.

The core benefit.

PSLF forgives the remaining balance on federal direct student loans after 120 qualifying monthly payments while employed full-time by a 501(c)(3) nonprofit or government employer.

For physicians, the typical math is: – $250K-$400K of medical school debt at residency graduation – 6-8% federal interest rate – 10 years of qualifying employment to hit 120 payments – Payments calculated on income-driven repayment (IDR) plans (typically 10-15% of discretionary income) – Forgiveness amount: balance remaining after 120 payments

During residency at $65K-$80K income, IDR payments are low (often $0-$400/month for interns, $300-$700/month for senior residents). Over 3-5 years of residency on IDR: total payments $15K-$30K.

Attending years at 501(c)(3) hospital with $300K-$500K income: IDR payments higher ($1,500-$3,500/month) but still less than the standard 10-year repayment amount. Over 5-7 attending years: total payments $90K-$240K.

Total payments across 10 years: $105K-$270K. Original balance with interest accrual: $300K-$500K. Forgiveness: $30K-$230K typically.

Tax treatment.

IRC §108(f)(1) excludes PSLF forgiveness from gross income for federal tax purposes. The forgiveness is tax-free at the federal level.

State tax conformity varies. Most states conform to federal exclusion. Some states (California, Indiana, Mississippi, North Carolina, Wisconsin) may tax the forgiven amount as state-source income. Check current state law.

For a physician with $200K of federal forgiveness: – Federal tax savings: $0 (excluded) – California state tax (if applicable): $200K × 11% = $22K state tax due – Total net benefit: $200K – $22K = $178K

For states that conform, the full forgiveness is tax-free.

Eligibility requirements.

1. Federal Direct Loans only. Federal Family Education Loans (FFEL) and private loans don’t qualify. If you have FFEL loans, consolidate to Direct Loans to qualify.

2. 501(c)(3) or government employer. Academic medical centers, large nonprofit hospital systems (Kaiser, Cleveland Clinic, Mayo, Geisinger, etc.), VA hospitals, and government clinics qualify. Many community hospitals are 501(c)(3). Private group practices and for-profit hospitals generally don’t qualify.

3. Full-time employment. Averaging 30+ hours per week, or your employer’s definition of full-time, whichever is greater. Combining multiple part-time positions that total full-time can work — but each employer must be a qualifying employer and the combined hours must be tracked.

4. Income-driven repayment plan. Standard 10-year repayment doesn’t qualify (you’d pay off the loan in those 10 years anyway, no forgiveness). Must be on IDR (PAYE, REPAYE/SAVE, IBR, or ICR).

5. 120 qualifying monthly payments. The payments don’t have to be consecutive. Months in deferment or forbearance generally don’t count (with limited exceptions). Months on standard 10-year repayment don’t count (must be on IDR).

6. Annual employment certification. Submit the PSLF Employer Certification Form to your loan servicer (now MOHELA) at least annually to confirm qualifying employment. The certifications are matched to your payment history.

The income-driven repayment plan choices (current status).

As of 2025-2026, the IDR landscape has changed significantly due to court actions affecting the SAVE plan. Verify current status with your servicer. The general options:

PAYE (Pay As You Earn): 10% of discretionary income (AGI minus 150% of federal poverty line). Forgiveness after 20 years for non-PSLF; 10 years for PSLF.

REPAYE / SAVE (in litigation): historically 10% (graduate loans) of discretionary income with subsidized interest for negative amortization. Status currently in flux.

IBR (Income-Based Repayment): 10% for newer borrowers, 15% for pre-2014 borrowers. Forgiveness after 20-25 years for non-PSLF.

ICR (Income-Contingent Repayment): 20% of discretionary income. Less favorable than the others.

For residents and early attendings, PAYE has historically been the favored choice (10% payment cap, predictable terms). Confirm current eligibility and rules.

The spouse income trap.

IDR payments are calculated on the borrower’s AGI. For married filing jointly, this means combined household AGI. A physician resident married to a high-earning spouse (engineer, attorney, software developer) may have IDR payments based on combined $200K+ income — much higher than payments based on resident salary alone.

Fix: married filing separately (MFS). PAYE and IBR (but not REPAYE/SAVE) allow MFS to exclude spouse income from the IDR calculation. MFS tax cost typically $3K-$8K higher annual income tax versus MFJ. Compare against the IDR payment savings.

Example: Resident at $70K married to engineer at $180K. Combined AGI $250K, MFJ IDR payment maybe $1,500/month. MFS using only resident’s income: IDR payment $300-$400/month. Savings: $1,100/month × 12 = $13,200/year. MFS tax cost: $4,000. Net: $9,200/year in savings via MFS.

Across 3 years of residency: $27,600 saved. Worth it.

The employer change trap.

If you switch from a 501(c)(3) hospital to a private practice during the 10-year PSLF window, your qualifying payments stop accruing. You don’t lose the prior qualifying payments — you can still reach 120 if you return to qualifying employment later. But every month at the private practice is a non-qualifying month, extending the timeline.

Many physicians plan: residency at academic medical center (4-7 years), early attending at 501(c)(3) hospital (3-5 years), then transition to private practice or higher-earning role after PSLF.

The critical question: do you make the most of income or make the most of PSLF? Run both paths.

Path A: PSLF route. Stay at 501(c)(3) for 10 years post-residency. Hit 120 payments. Forgiveness $200K. Net 10-year compensation (assuming $350K attending salary): $3.5M minus IDR payments minus taxes, plus $200K of forgiveness.

Path B: Private practice route. Refinance loans privately for lower rate (4-5% vs 6-8%). Earn higher private practice salary ($500K average). Pay loans aggressively over 5-7 years. Net 10-year compensation (assuming $500K average salary): $5M minus loan payments minus taxes.

Path B usually wins on raw compensation but ties up cash flow servicing the debt. Path A has the psychological benefit of debt elimination plus lower stress about repayment.

Run the actual numbers for your specialty. Hospitalists, primary care, and academic specialties often favor Path A. Surgical specialists and procedural specialties often favor Path B.

Documentation discipline.

– Submit PSLF Employer Certification Form annually – Keep copies of all employer certifications – Track every payment made – Confirm qualifying status of each payment with the loan servicer – File Form 1040 reporting student loan interest deduction (limited but real) during repayment years – After forgiveness, ensure the loan servicer reports the forgiveness correctly on Form 1099-C (typically box 5 for IRC §108(f) exclusion)

After forgiveness.

Loans are gone. No income to report (federal). State tax may apply in non-conforming states (file Schedule appropriate to state).

For doctor tax strategies high income planning, PSLF is a real subsidy worth $100K-$300K to qualifying physicians. The optimal path depends on specialty, employer type, and personal situation. Run the numbers carefully and start planning during medical school — the choices you make at residency graduation about employer type, loan consolidation, and IDR plan selection compound over the 10-year window.

I’m a 1099 locum tenens internist making $400K with no employer benefits. What’s the cash balance plan plus solo 401(k) stack and how much can I contribute pre-tax?

Locum tenens internists are perfectly positioned for the cash balance plus solo 401(k) stack. No employer 401(k) to coordinate around, full $70K solo 401(k) headroom, and enough income to support a substantial defined benefit contribution. Let me walk through the numbers.

The structure.

You form an S-corp (or LLC taxed as S-corp) to receive your 1099 income. The S-corp pays you a reasonable W-2 salary and treats the rest as K-1 distributions. The S-corp sponsors two retirement plans:

Plan 1: A solo 401(k) with profit-sharing. Plan 2: A cash balance pension plan.

Both plans are sponsored by the same S-corp employer. You’re the sole participant in each. Annual contributions to both plans are deductible from the S-corp’s income (which reduces your K-1 income pass-through) — except that 401(k) contributions on the W-2 side go through different accounting (employee deferrals reduce W-2 box 1, profit-sharing employer contributions reduce S-corp net income).

Reasonable comp setup.

For an internist at $400K of 1099 net income (let’s call it $400K of net S-corp income before W-2 and retirement contributions), reasonable comp benchmark is roughly $200K-$250K based on BLS OES median for internal medicine.

Start with $200K W-2 salary. The remaining $200K of net S-corp income is available for retirement contributions plus K-1 distribution.

Solo 401(k) contributions.

Employee deferral (from W-2 salary): $23,500 for 2025 (projected same or slightly higher for 2026). This comes out of your W-2, reducing W-2 box 1.

Employer profit-sharing: 25% of W-2 compensation. $200K × 25% = $50K. But capped by the IRC §415(c) overall limit of $70K total combined contributions to the solo 401(k). $23,500 deferral + $46,500 profit-sharing = $70K total. So profit-sharing maxes at $46,500 (not the full $50K from the 25% calculation).

Total solo 401(k) contributions: $70K.

Age 50+ catch-up: additional $7,500 employee deferral, bringing 415(c) limit to $77,500. (You said age was unspecified but I’m assuming under 50 for this calculation; adjust if you’re 50+.)

Cash balance plan contributions.

The cash balance plan is a separate plan. Its annual contribution is determined by the plan’s actuary based on: – Your age – Years to expected retirement – The plan’s target benefit at retirement (capped by IRC §415(b) maximum benefit, $280K for 2025 / projected $290K for 2026) – The plan’s interest crediting rate

At age 45 (assuming this for the example), targeting retirement at 65, the cash balance contribution can be roughly $130K-$170K depending on plan design.

At age 50: roughly $180K-$220K. At age 55: roughly $250K-$300K. At age 60: roughly $300K-$400K.

The contribution grows with age because the actuary has fewer years to accumulate the targeted retirement benefit.

For a 45-year-old internist, let’s use $150K as the cash balance contribution.

Total stack for a 45-year-old at $400K net: – Solo 401(k) employee deferral: $23,500 – Solo 401(k) employer profit-sharing: $46,500 – Cash balance plan: $150,000 – Total pre-tax contributions: $220,000

That’s 55% of your gross income going to retirement, pre-tax.

Tax savings.

Assuming 32% federal marginal + 9% California state + 3.8% NIIT on K-1 distribution portion (depending on material participation) = roughly 41-44% combined marginal rate on the contributed amounts.

$220K × 42% = $92K of current-year tax savings.

Cash flow check.

Gross S-corp income: $400K. Reasonable comp W-2: $200K. Profit-sharing employer contribution: $46,500. Cash balance contribution: $150K. Cash remaining for K-1 distribution to owner: $400K – $200K – $46.5K – $150K = $3.5K K-1 distribution.

From your W-2 of $200K, the employee 401(k) deferral of $23.5K is excluded. W-2 box 1: $176.5K. Federal/state income tax on $176.5K: roughly $45K-$50K. FICA/Medicare on $200K W-2: $200K × 7.65% = $15.3K (employee portion). Plus the additional Medicare 0.9% above $200K MFJ: 0%. Employer side of FICA: $15.3K (S-corp pays).

Net take-home from the W-2 after tax: $200K – $23.5K – $50K – $15.3K = $111K. Plus K-1 distribution: $3.5K. Total personal cash flow: $114.5K.

Is that enough to live on? Depends on your fixed costs. For most internists, $114K of after-tax personal cash is workable, especially if the $220K of retirement contributions is building toward a $5M-$10M retirement nest.

If you need more current cash flow, reduce the cash balance contribution. The cash balance contribution is the flexible one — actuary can target lower contributions if needed. Solo 401(k) is also flexible (you can contribute less than the max).

Minimum funding considerations.

Cash balance plans have minimum funding requirements under IRC §430. Once you establish the plan with a target contribution level, you must fund at least the minimum required contribution each year (typically close to the targeted amount). Can’t easily skip years.

Fix: design the plan with conservative target contributions, then make discretionary additional contributions in good years. Or fund the minimum and use other vehicles (taxable account, real estate) for excess savings.

Locum tenens cash flow volatility.

Locum income can be variable — some months $50K, some months $20K. The cash balance plan minimum funding doesn’t care about your month-to-month variation. Plan for the annual contribution and budget cash flow across the year.

If you have a bad income year (say, $200K instead of $400K), the cash balance plan’s minimum funding may exceed your S-corp’s net income, forcing the S-corp to lose money. Bad outcome.

Mitigation: keep a cash reserve in the S-corp equal to 6-12 months of contributions. Don’t fully drain the S-corp each year.

Locum-specific deductions.

In addition to retirement contributions, locum tenens internists have unique deductions: – Travel between assignments (if away from tax home) – Temporary lodging at assignments – Meals while away from tax home (50% deductible) – Multiple state medical license fees – DEA registration – Credentialing fees – Malpractice insurance (tail coverage if needed) – CME (with travel) – Phone, computer, internet allocated to business use – Continuing education

Document with mileage logs, receipts, itineraries. The accountable plan through the S-corp lets you reimburse these tax-free.

For a busy locum, business expenses might total $30K-$60K per year on top of retirement contributions. Plus any home office allocation.

Forms and reporting.

– Form 1120-S: S-corp return – Schedule K-1: pass-through to you – Schedule E on personal return: K-1 income – Form W-2: your salary from the S-corp – Form 5500-SF: solo 401(k) filing (required if balance exceeds $250K) – Form 5500: cash balance plan annual filing (required) – Schedule SB (Form 5500): cash balance actuarial certification – IRS Notice 2008-1: addresses some accounting and timing issues for cash balance plans

The annual cost of administering both plans: – Solo 401(k) administration: $0-$200/year (Fidelity and Schwab offer free solo 401(k)s; some prototype plans have annual fees) – Cash balance plan administration: $3,000-$6,000/year for actuary, recordkeeper, and TPA – 5500 filing fees: included in TPA fee usually – Total annual cost: $3K-$6.5K

Versus tax savings of $90K+, the administrative cost is rounding error.

Long-term wealth building.

Projected retirement balance after 20 years of running this stack: – Annual contribution: $220K – Growth rate: 7% – Years: 20 – Balance: $9.6M

Versus running just the solo 401(k) at $70K/year: $3.07M after 20 years.

The cash balance plan triples the retirement accumulation.

At retirement, the cash balance plan can be rolled into an IRA (lifetime tax deferral). The solo 401(k) can also roll to IRA. Combined balance gets RMDs starting at age 73. Plan Roth conversions in low-income early-retirement years to manage the future tax burden.

For your situation as a $400K locum tenens internist, the cash balance plus solo 401(k) stack is the single highest-value tax strategy available. Get this in place by year-end and you can save $90K+ in your first year of running it. Coordinate with a CPA experienced with physician practices and a pension actuary who designs cash balance plans regularly — not all CPAs handle these effectively.
