Tax Accountant for Doctors — NYC

A New York tax accountant for doctors matters because physician income is taxed harder and in more ways than almost any other profession, and a generalist preparer rarely sees the whole picture. Doctors hit the top federal brackets early, face New York State and often New York City income tax stacked on top, owe an extra 0.9 percent Additional Medicare Tax on high wages, and frequently get phased out of breaks like the qualified business income deduction. A New York tax accountant for doctors who works with physicians every day knows where the money leaks and how to plug it. The work is less about filing the return and more about structuring the year so the combined federal, state, and city load is as low as the law allows.

Here is what makes physician taxes distinct. High W-2 wages from a hospital or group, often with 1099 moonlighting income layered on, create a mixed picture that needs both Schedule C handling and wage planning. The Additional Medicare Tax adds 0.9 percent on Medicare wages and self-employment income over 200,000 dollars for single filers and 250,000 dollars for joint filers, with no cap, so a high-earning doctor pays it on a large slice of income. The net investment income tax adds another 3.8 percent on investment income once modified adjusted gross income crosses those same thresholds. The IRS Additional Medicare Tax topic spells out the 0.9 percent rules, the net investment income tax page covers the 3.8 percent, and the Social Security and Medicare withholding topic covers the base rates.

Worked example. A New York hospitalist earns 320,000 dollars in W-2 wages and 40,000 dollars in 1099 locum income. On the wages alone, the Additional Medicare Tax adds 0.9 percent on the amount over 200,000 dollars, roughly 1,080 dollars, and the 1099 income carries self-employment tax plus more Additional Medicare Tax. Layer New York State tax, which tops out above 10 percent for high earners, and New York City resident tax near 3.9 percent, and the marginal rate on the next dollar can approach 50 percent. A physician-focused accountant looks at that and asks where retirement contributions, entity structure for the 1099 work, and timing can claw some of it back. A generalist often just reports the numbers and moves on. The same doctor who moves a residence from the city to a suburb, or who shifts the location of taxable investments, can change the all-in rate meaningfully, and those are conversations a physician specialist starts before the year is over.

The mistake we see every year is doctors who use the same preparer they had in residency, when income was modest and the return was simple, and never upgrade as their pay triples. The strategies that matter at 350,000 dollars of income, backdoor Roth contributions, defined benefit plans, S corporation structuring for side income, charitable bunching, are invisible to a preparer who only does data entry. The other error is ignoring the 1099 side, treating locum or telehealth income as an afterthought when it is often the most plannable part of the picture. A third trap is student loan interaction, where a married physician on an income-driven repayment plan can have monthly payments swing by hundreds of dollars depending on whether the couple files jointly or separately, a decision that has to be modeled rather than guessed. There is also a residency-and-domicile question for doctors who train in one state and practice in another, or who carry income from multiple states, where part-year and nonresident filings can either create double tax or, handled well, a credit that prevents it.

The fastest wins a New York tax accountant for doctors finds usually sit in your 1099 income, because that is the part you control. Hospital W-2 wages are largely fixed, but locum tenens, telehealth, expert witness work, and side consulting all flow as self-employment income that can be structured. The two big levers are entity choice, which can cut self-employment tax, and retirement contributions, which can shelter a large share of that income from tax entirely. A New York tax accountant for doctors who handles physician 1099 income routinely knows exactly when each lever pays off and when it does not.

Here is the mechanics. As a sole proprietor, your 1099 income faces the full 15.3 percent self-employment tax up to the Social Security wage base, then 2.9 percent Medicare with no cap, plus the 0.9 percent Additional Medicare Tax over the threshold. If your moonlighting income is substantial, electing S corporation treatment lets you pay yourself a reasonable salary and take the rest as distribution, trimming the Medicare portion of the tax on the distribution. Separately, a solo 401k or SEP-IRA built on the 1099 income lets you deduct large contributions. For 2026 the solo 401k employee deferral is 24,500 dollars plus an 8,000 dollar catch-up at 50 or older, with employer contributions on top. The IRS self-employment tax page covers the rates, the one-participant 401k page covers the solo plan, and the S corporations page covers the election.

Worked example. A New York anesthesiologist earns 290,000 dollars in W-2 wages and 90,000 dollars in 1099 locum income. Because her W-2 wages already exceed the Social Security wage base of 184,500 dollars for 2026, her 1099 income only faces the 2.9 percent Medicare plus 0.9 percent Additional Medicare, not the full 15.3 percent, which changes the S corporation math. The bigger win is retirement. She opens a solo 401k on the locum income. The employer contribution alone, 25 percent of her self-employment compensation, can shelter close to 18,000 dollars, and because her W-2 plan deferral may already be used at the hospital, the planning has to coordinate both plans so she does not exceed the single overall employee deferral limit. Done right, she shelters a large chunk of the 90,000 dollars and cuts her combined federal, state, and city tax by several thousand dollars.

The mistake we see every year is physicians who let 1099 income pile up untouched, paying full freight on every dollar because nobody set up a plan around it. The other error is the opposite, electing an S corporation for a small amount of side income where the payroll and compliance cost exceeds the savings, or where the W-2 wage base already caps the Social Security tax and removes most of the benefit. For a doctor whose day-job wages already pass the wage base, the classic S corporation salary-versus-distribution savings shrinks to the Medicare portion only, which is a smaller prize than the usual pitch suggests. A third error is forgetting that 1099 income can trigger or increase quarterly estimated payment obligations, since no one withholds on it. The right answer depends on the numbers, and for doctors the interaction between W-2 wages and 1099 income changes the usual playbook. A further wrinkle for hospital-employed doctors is that some employment contracts restrict outside work or require disclosure, so the entity and tax plan for moonlighting has to sit alongside the contract terms rather than ignore them.

For high-earning physicians, retirement planning is the most powerful tax tool available, and a New York tax accountant for doctors should be pushing you to use every account you qualify for. Doctors are in the top brackets, so every dollar moved into a pre-tax retirement account saves close to 50 cents once you stack federal, New York State, and New York City tax. The accounts a physician can use go well beyond the basic 401k, and the layering of a hospital plan, a backdoor Roth, and a plan built on side income is exactly where a New York tax accountant for doctors earns the fee.

Here is the toolkit. First, max the hospital or group 401k, which for 2026 allows a 24,500 dollar employee deferral plus an 8,000 dollar catch-up at 50 or older. Second, run a backdoor Roth IRA, because physicians earn too much to contribute to a Roth directly but can contribute to a nondeductible traditional IRA and convert it, using the 2026 IRA limit of 7,500 dollars or 8,000 dollars with catch-up. Third, if you have meaningful 1099 income, layer a solo 401k or SEP-IRA on top. Fourth, for an established high earner with strong cash flow, a defined benefit or cash balance plan can shelter far more than any defined contribution plan, sometimes well over 100,000 dollars a year. The IRS retirement plans for self-employed page covers the self-employed options, the IRA contribution limits page covers the Roth backdoor inputs, and the defined benefit plan page covers the high-contribution option.

Worked example. A New York radiologist, age 52, earns 400,000 dollars, mostly W-2 with 60,000 dollars of 1099 reads. She maxes her hospital 401k at 32,500 dollars including catch-up. She does a backdoor Roth of 8,000 dollars. On the 1099 income she opens a solo 401k and, because her employee deferral is used at the hospital, contributes the employer side, roughly 11,000 dollars. Then, because her income and cash flow support it, she adds a cash balance plan contribution of 90,000 dollars. Stack those and she shelters well over 130,000 dollars of income in a single year. At a combined marginal rate near 50 percent, that is more than 60,000 dollars of tax saved, every year she runs the plan. The cash balance plan does require an actuary and a multi-year funding commitment, so it fits a physician with predictable high earnings rather than one with a volatile income.

The mistake we see every year is physicians who only fund the hospital 401k and stop there, leaving the backdoor Roth, the side-income plan, and the defined benefit option untouched. They assume they make too much to do anything else, when in fact high income is exactly what unlocks the bigger accounts. The other error is botching the backdoor Roth by leaving pre-tax IRA money in the account, which triggers the pro-rata rule and a surprise tax bill on the conversion, so any existing traditional or SEP-IRA balance has to be addressed first. A third trap is the overall employee deferral limit, which applies per person across all 401k plans, so a doctor with both a hospital plan and a solo 401k cannot double up on the employee deferral, only on the employer side. A further option for doctors whose employer plan allows it is the mega backdoor Roth, where after-tax 401k contributions are converted to Roth, letting a high earner move far more into Roth space than the standard limits suggest, though only certain plans permit it.

A New York tax accountant for doctors plans around two surtaxes most physicians do not even notice until they bite, the 0.9 percent Additional Medicare Tax and the 3.8 percent net investment income tax. Both kick in at the same income thresholds, 200,000 dollars for single filers and 250,000 dollars for joint filers, and almost every working physician blows past them. The Additional Medicare Tax hits your wages and self-employment income, while the net investment income tax hits your dividends, interest, capital gains, and rental income. Together they add a quiet layer of tax on top of the regular brackets, and a New York tax accountant for doctors who plans for them can soften the blow.

Here is how each one works. The Additional Medicare Tax is 0.9 percent on Medicare wages and self-employment income above the threshold, with no upper cap, and your employer withholds it automatically on wages over 200,000 dollars regardless of filing status, which can cause over or under withholding depending on your household. The net investment income tax is 3.8 percent on the lesser of your net investment income or the amount your modified adjusted gross income exceeds the threshold. The IRS Additional Medicare Tax questions and answers explain the wage and self-employment rules, the net investment income tax questions and answers cover the 3.8 percent, and Form 8959 is where the Additional Medicare Tax gets reconciled at filing.

Worked example. A married New York physician couple, both working, earn 420,000 dollars in combined wages and 30,000 dollars in dividends and capital gains. The Additional Medicare Tax applies 0.9 percent to wages over 250,000 dollars, roughly 1,530 dollars. The net investment income tax applies 3.8 percent to the 30,000 dollars of investment income because their income is well over the threshold, another 1,140 dollars. That is 2,670 dollars of surtax that has nothing to do with their regular brackets. Now plan around it. Shifting investment income into tax-advantaged accounts, harvesting losses to offset gains, and timing capital gains into lower-income years can shrink the net investment income tax base. Municipal bond interest, which is generally exempt, can also reduce the investment income that feeds the 3.8 percent, though the yield tradeoff has to pencil out for a high earner.

The mistake we see every year is dual-physician couples who get surprised at filing because each employer withheld the Additional Medicare Tax based only on that job, missing the household threshold interaction, leaving a balance due that Form 8959 then reconciles upward. The other error is ignoring the net investment income tax entirely and holding income-producing investments in taxable accounts when they could sit in retirement accounts shielded from the 3.8 percent. A third issue is rental real estate, where the net investment income tax can apply to rental profit unless the physician qualifies as a real estate professional, a status with strict hour requirements that a full-time doctor almost never meets. A further planning angle is charitable giving. Donating appreciated stock rather than cash lets a high-earning physician avoid the capital gain entirely, which keeps that gain out of the net investment income tax base while still producing a deduction at fair market value. Bunching several years of gifts into one through a donor advised fund can increase the benefit in a high-income year. These taxes are predictable, which means they are plannable. We map both surtaxes into the physician plan and adjust withholding and investment location to manage them. Our tax strategy consulting handles the surtax planning, and our investment coordination service positions assets to limit the net investment income tax.

Good records are what let a New York tax accountant for doctors actually find your deductions instead of guessing at them, and physicians tend to have more moving pieces than most clients. Between W-2 wages, 1099 moonlighting, continuing education, malpractice premiums, licensing fees, professional dues, and unreimbursed practice costs, there is a lot to track, and the deductible items hide in the noise. A New York tax accountant for doctors can only claim what you can document, so the records you keep through the year directly control how low your bill goes. The IRS expects substantiation, and for a high earner who is more likely to draw scrutiny, clean records are protection as well as savings.

Here is what to keep. All income documents, W-2s, every 1099-NEC and 1099-MISC from locum, telehealth, and consulting work, and 1099-K forms from payment platforms. For 1099 income, records of business expenses, continuing medical education tuition and travel, board certification and license renewal fees, professional society dues, malpractice insurance you pay personally, medical equipment and supplies, and a mileage log for travel between work sites. For investments, brokerage statements showing dividends, interest, and the cost basis of anything sold, which feeds the net investment income tax calculation. For retirement, records of every contribution to coordinate the accounts. The IRS recordkeeping page covers what to retain, the business expenses page covers what qualifies, and the Schedule C page covers where the 1099 expenses land.

Worked example. A New York physician with 75,000 dollars of 1099 telehealth income keeps a clean file all year. She tracks 4,500 dollars in continuing medical education, 3,200 dollars in malpractice premiums she pays herself, 1,800 dollars in licensing and board fees, 2,100 dollars in professional dues and journals, and a 200 dollar per month home office for charting. Add a mileage log for travel between facilities. Those documented costs reduce her Schedule C net income by well over 15,000 dollars, saving roughly 7,000 dollars in combined federal, state, and city tax at her marginal rate. Without the records, most of that would have been left on the table because nobody could prove it. One nuance for physicians is that costs tied to your W-2 hospital job, paid personally and not reimbursed, are generally not deductible on a federal return today, so the deduction value lives almost entirely on the 1099 side. That distinction decides whether an expense saves you anything at all.

The mistake we see every year is physicians who pay these professional costs out of a personal account, never categorize them, and arrive at filing with no way to separate the deductible items from personal spending. The other error is discarding brokerage cost basis records, which forces a worse tax outcome on investment sales and complicates the net investment income tax math. A third common slip is failing to keep mileage and travel logs as you go, then trying to rebuild a year of trips from a calendar in April, which is exactly the kind of estimate an examiner challenges first. A further record worth keeping is documentation for any home office used for telehealth, including square footage and a note on exclusive business use, because the home office deduction is allowed against 1099 income but only when the space genuinely meets the exclusive-use test. The fix is a dedicated business account for 1099 work, a simple expense-tracking habit, and a year-end folder of the key documents. We give physician clients a tailored checklist so nothing deductible slips through. Our bookkeeping service keeps the 1099 records clean, and our tax compliance service makes sure the deductions you claim are documented and defensible.
