403(b) vs 401(k) Tax Treatment: How the Two Plans Diverge on Limits, Catch-Ups, ERISA, and Withdrawals

You’re in one of the best retirement contribution scenarios available to a W-2 employee. The combination of a 403(b), a 457(b), the age-50 catch-up, and the 15-year catch-up gives you total elective deferral capacity that’s well beyond what private-sector 401(k) employees can access. Let me walk through the specifics.

The baseline 2026 elective deferral limits.

Your 403(b) elective deferral limit under §402(g) is $24,500 for 2026. Same as a 401(k). The age-50 catch-up adds $7,500 (you’re 52, so you qualify). Standard 403(b) total for you: $31,000.

Your 457(b) elective deferral limit is separately $24,500 for 2026. The age-50 catch-up on the 457(b) adds $7,500. Standard 457(b) total for you: $31,000.

The 457(b) and 403(b) limits don’t aggregate. This is the key rule. §402(g) covers the 401(k)/403(b) world; §457(b) is governed by its own elective deferral limit under §457(e)(15). The two limits are independent.

So your standard combined limit across both plans for 2026: $32,500 + $32,500 = $65,000.

That’s already far more than the private-sector 401(k) limit of $31,000. Strong starting point.

The 15-year catch-up under §402(g)(7).

This is the 403(b)-only feature that adds to your capacity. You have 18 years of service with the same employer (public school district) — qualifying employer under §170(b)(1)(A)(ii). The 15-year catch-up is available to you.

The annual 15-year catch-up amount is the least of three numbers:

1. $3,000 per year.

2. $15,000 minus prior 15-year catch-up amounts you’ve already used.

3. $5,000 times years of service, minus prior elective deferrals (excluding age-50 catch-up amounts).

Let me run the calculation for you specifically.

Prior elective deferrals (excluding age-50 catch-ups). I don’t know your actual contribution history, but let me assume you’ve been contributing roughly $15,000/year for the past 18 years (typical for a teacher at your income level). Cumulative prior deferrals: $270,000.

Prior 15-year catch-up amounts: assume $0 (most teachers never use this; their advisor doesn’t know about it).

Number 1: $3,000.

Number 2: $15,000 – $0 = $15,000.

Number 3: $5,000 × 18 = $90,000. Minus prior deferrals of $270,000 = NEGATIVE $180,000. The result can’t be less than zero, but effectively it means you’ve already ‘used’ more than the $5,000-per-year credit through ordinary contributions. The third prong evaluates to $0.

Least of {$3,000, $15,000, $0}: $0.

Result: your 15-year catch-up for 2026 is $0. The third prong eliminates your eligibility because your cumulative prior deferrals exceed $5,000 × years of service.

This is the trap I mentioned in the post. The 15-year catch-up looks attractive in theory but is mostly unavailable in practice for teachers who’ve been contributing consistently. The rule was designed for teachers who under-contributed in earlier years and want to make up ground — not for teachers who maxed out throughout their career.

Let me run an alternative scenario to show when the 15-year catch-up actually helps.

Scenario: a teacher who contributed only $5,000/year for the first 10 years and then ramped up to $20,000/year for the next 8 years. Cumulative prior deferrals: $50,000 + $160,000 = $210,000.

Number 3: $5,000 × 18 – $210,000 = $90,000 – $210,000 = NEGATIVE. Still zero.

Let me try another scenario. A teacher who contributed $0 for the first 8 years (perhaps was an aide before becoming certified) and then contributed $15,000/year for 10 years. Cumulative: $150,000.

Number 3: $5,000 × 18 – $150,000 = -$60,000. Still negative.

The 15-year catch-up only helps if cumulative prior deferrals are less than $5,000 × years of service. For an 18-year teacher, that means prior deferrals under $90,000 total — about $5,000/year on average. Most teachers contribute more than this once they’re earning a teacher’s salary.

So for you specifically: skip the 15-year catch-up math. It won’t add anything.

Your realistic 2026 contribution capacity.

403(b): $24,500 elective deferral + $8,000 age-50 catch-up = $32,500.

457(b): $24,500 elective deferral + $8,000 age-50 catch-up = $32,500.

Total: $62,000.

At your $95K salary, $62,000 is 65% of gross pay. Most teachers can’t actually contribute this much — they need cash for living expenses. But the capacity is there if you have other income sources or a spouse earning the household living expenses.

Practical contribution strategy for someone at your income.

Step 1: max the 403(b) match if your district provides one. Most public school districts don’t, but check. If yours does, contribute enough to get the full match before doing anything else. Free money.

Step 2: contribute to the 457(b) before the 403(b) for additional deferrals. The 457(b) at a governmental employer holds assets in trust (under §457(g)) so it’s protected from district financial distress. The 457(b) has no §72(t) early withdrawal penalty — you can take distributions at any age (taxed as ordinary income) without the 10% penalty. This makes the 457(b) more flexible than the 403(b).

Step 3: contribute to the 403(b) for any remaining capacity after maxing the 457(b).

Why this order. The 457(b) has the flexibility advantage (no early withdrawal penalty). If you might retire before 59.5 and need access to retirement funds, the 457(b) provides that without penalty. The 403(b) requires age 55 separation or age 59.5 for penalty-free access. So load up the 457(b) first to preserve maximum flexibility, then use the 403(b) for the excess.

Exception: if your district has a particularly strong 403(b) match formula and weak 457(b) match (rare but possible), reverse the order to capture the better match.

Roth versus traditional decision.

At $95K income, you’re in the 22% federal bracket for 2026 (married filing jointly) or potentially 24% bracket for single filers. Your marginal rate is probably 22-24% federal plus state.

In retirement, you’ll have a public school pension (probably 50-80% of final salary) plus Social Security plus retirement account distributions. Your retirement income could easily match or exceed your current income. Marginal rate in retirement: similar or higher.

For a Connecticut teacher, NY teacher, NJ teacher with strong pension: retirement marginal rate could be 24-32%, exceeding current marginal rate.

For someone with retirement marginal rate likely matching or exceeding current rate, Roth contributions make sense. Pay the 22-24% rate now; grow tax-free forever.

For someone with retirement marginal rate likely lower than current rate (limited pension, modest Social Security), traditional contributions make sense.

Your pension situation matters. If you have a strong defined benefit pension, lean Roth. If you have a weak pension or no pension (some private school 403(b) participants), lean traditional.

The SECURE 2.0 §603 high-earner rule doesn’t affect you at $95K — the threshold is roughly $160K. So you have full discretion on traditional vs. Roth for your catch-up.

SECURE 2.0 super catch-up for ages 60-63.

You’re 52 now. The super catch-up doesn’t apply to you for several years. Starting at age 60 (in 8 years), the catch-up increases to 150% of the regular amount. For 2026 numbers, that’s $11,250 instead of $7,500. So at age 60-63, your 403(b) elective deferral capacity will be $23,500 + $11,250 = $34,750, plus another $34,750 in the 457(b) = $69,500. The super catch-up window is 4 years (60, 61, 62, 63).

Planning move: front-load contributions in your 50s with normal catch-up, then if your income permits, ramp up further in your early 60s to capture the super catch-up. Many teachers retire at 60-62, which doesn’t allow capture of the super catch-up unless they continue working.

State-specific complications.

If you’re in a state with mandatory teacher pension contributions (Texas, California, Massachusetts, others), the pension contribution may be pre-tax, post-tax, or vary by state. Coordinate with your pension contribution. The pension contribution doesn’t count toward §402(g) elective deferral limits — it’s separate.

If you’re in a state with conformity differences (Pennsylvania, others), the federal pre-tax treatment may not flow through to state tax. Confirm state treatment with your tax preparer.

Bottom line for your specific situation.

Max both plans for 2026: $32,500 in the 403(b) + $32,500 in the 457(b) = $65,000 total. Skip the 15-year catch-up calculation (won’t help you given your contribution history). Choose Roth if you expect retirement income to match current income; traditional if you expect retirement income to be lower. Reassess each year as the limits change with inflation. Re-run the calculation when you hit age 60 to take advantage of the super catch-up if your income permits.

For a public school teacher with 18 years of service, the available retirement contribution capacity is significantly higher than most teachers realize. Capture it if you can — the tax-deferred or tax-free compounding over 13 years to retirement is meaningful even at modest annual amounts.

Documentation: keep contribution confirmations from both plans. Form W-2 will show 403(b) deferrals in Box 12 code E and 457(b) deferrals in Box 12 code G. The IRS reconciles these against the §402(g) limit (for the 403(b)) and the §457(b) limit (for the 457(b)) separately.

Physicians with hospital 403(b)s and solo practice income hit this question constantly, and the answer is more restrictive than most online retirement-planning content suggests. Let me work through the rules carefully, because the §415(c) aggregation for 403(b)s catches a lot of high-earners off guard.

The relevant code provisions.

§402(g) — the elective deferral limit. $24,500 for 2026, with $8,000 age-50 catch-up. Applies in aggregate to the participant across all 401(k), 403(b), and SIMPLE plans of all employers (related or unrelated).

§415(c) — the overall annual additions limit. The lesser of $70,000 or 100% of compensation for 2026. Applies per plan, but with aggregation rules under §415(f).

§415(c)(3)(E) — the special 403(b) aggregation rule. A 403(b) is treated as if maintained by the participant rather than the employer. The 403(b) is so aggregated under §415 with any plans of businesses the participant ‘controls’ (50%+ ownership) for purposes of the §415(c) limit.

This is the rule that catches you. Let me explain the application.

Your situation.

Hospital 403(b). You’re a W-2 employee of the hospital. The hospital sponsors the 403(b). You contribute, hospital may match.

Solo 401(k). You’re self-employed in your side practice (1099 contractor or sole proprietor). You sponsor a solo 401(k) for the side practice income. You contribute as employee and as employer.

Under §415(c)(3)(E), your hospital 403(b) is treated as ‘maintained by you’ for §415 purposes. Your solo 401(k) is also maintained by you (you own 100% of the side practice). The two plans are aggregated under §415.

Result: a single $70,000 §415(c) limit applies to total annual additions across the 403(b) and solo 401(k) combined.

The practical impact.

Let’s run numbers. Suppose:

Hospital 403(b) contributions for 2026: – Your elective deferral: $23,500 – Age-50 catch-up (if applicable): $7,500 – Hospital match (assume 6% of $200K salary at hospital): $12,000 – Total annual additions in 403(b): $43,000 (without catch-up) or $43,000 still (catch-ups don’t count toward §415(c))

Note: §414(v) catch-up contributions are excluded from the §415(c) limit. So the $7,500 catch-up doesn’t count toward §415(c). Total 403(b) §415(c)-counted additions: $23,500 + $12,000 = $35,500.

Now your solo 401(k). You can’t make additional employee elective deferrals because §402(g) is aggregated across plans — you’ve already maxed the $23,500 (and $7,500 catch-up if applicable) at the hospital 403(b). The solo 401(k) only gets employer contributions.

Solo 401(k) employer contribution. As a sole proprietor, the maximum employer contribution is 20% of net self-employment income (after deducting half of self-employment tax). Let’s say your side practice has net SE income of $100,000. After deducting half of SE tax (roughly $7,000), net SE earnings are $93,000. Maximum employer contribution: 20% × $93,000 = $18,600.

Solo 401(k) §415(c)-counted additions: $18,600.

Combined under §415(c): $35,500 + $18,600 = $54,100. Under the $70,000 cap. OK.

But now consider a higher side practice income. Suppose net SE earnings are $250,000. 20% × $250,000 = $50,000 employer contribution intended.

Combined under §415(c): $35,500 + $50,000 = $85,500. Exceeds $70,000 by $15,500.

You cannot contribute the full $50,000 to the solo 401(k). The aggregated limit forces you to reduce the solo 401(k) employer contribution to $34,500 ($70,000 – $35,500). You lose $15,500 of capacity due to the aggregation.

This is the trap.

The scenario where aggregation doesn’t apply.

If you didn’t have a 403(b) and instead had a 401(k) at the hospital (treated as the hospital’s plan, not yours), the 401(k) wouldn’t aggregate with your solo 401(k) under §415. The two plans would each independently have a $70,000 §415(c) cap.

Unfortunately, you can’t choose your hospital’s plan type. The hospital sponsors what it sponsors.

The scenario where you can avoid the aggregation.

Option A: Take W-2 wages from a side gig at an unrelated employer. If your side income is from a W-2 position at a separate employer (rather than self-employment), the unrelated employer’s 401(k) is not aggregated with your 403(b) under §415. Each plan has its own $70,000 cap.

But this requires you to actually be employed by someone else, which may not match your side practice structure.

Option B: Structure the side practice through a separate entity that you don’t ‘control.’ This is difficult — by definition, you operate your own side practice, so the entity is yours. The only way to avoid aggregation is to have an unrelated party with 50%+ ownership (which doesn’t make commercial sense for most side practices).

Option C: Set up a defined benefit plan in the side practice. The §415(b) defined benefit limit is separate from §415(c). A cash balance plan or traditional defined benefit plan funded by your side practice can stack on top of the 403(b)/solo 401(k) §415(c) limit. This is the most powerful planning move for high-income physicians with substantial side income.

For a 50-year-old physician with $250K of side income, a defined benefit plan can permit additional contributions of $100K-$200K per year, fully aggregated separately from the §415(c) limit. The cost is plan setup ($5K-$10K), annual actuarial fees ($2K-$5K), and the commitment to continue funding for multiple years. For high-income physicians, the savings dwarf the costs.

Option D: Reduce side practice income through legitimate business expenses, vehicle deductions, home office, retirement plan deductions for any side practice employees. Lower SE income means lower §415(c) ceiling problem.

The SECURE 2.0 high-earner Roth catch-up complication.

At $450K, you’re well over the $145K-$160K SECURE 2.0 §603 threshold. Starting 2026, your catch-up contributions must be Roth. Your hospital 403(b) needs to have a Roth option for you to continue making catch-ups. If it doesn’t, you’ll lose the catch-up amount until they add it.

Most hospitals have added Roth options to comply. Confirm with your hospital benefits department.

Reporting and compliance.

§415(c) violations are reported through plan amendments and corrective distributions. Excess annual additions are distributed back to the participant with Form 1099-R code 8 (excess contribution distribution). The participant pays income tax on the excess plus 10% penalty if under 59.5.

Form 5500 and the IRS examination process will look for §415(c) aggregation issues for participants with multiple plan filings. The IRS data-matches across plans and flags potential violations.

If you discover an excess after the fact, work with both plan administrators to coordinate the corrective distribution. The plan that is ‘second in time’ for the contribution typically takes the corrective distribution, but the rules are flexible. Get a tax professional involved — the correction is complex.

My specific recommendation for your situation.

Step 1: Quantify the 403(b) annual additions for 2026. Get the hospital’s match formula. Calculate total contributions.

Step 2: Quantify the solo 401(k) capacity given the §415(c) aggregation. Calculate maximum employer contribution as $70,000 minus the 403(b) annual additions.

Step 3: If the §415(c) cap is binding, consider a defined benefit / cash balance plan in the side practice to stack on additional contributions. For $450K total income, the math typically supports this.

Step 4: Coordinate the Roth catch-up under SECURE 2.0 §603. Confirm hospital has Roth option.

Step 5: Run multi-year projections. Side practice income that grows in future years will hit the §415(c) cap harder; plan now for the structural choices that make the most of lifetime contributions.

The Reed Corporation works with physicians in this exact scenario. The §415(c) aggregation rule for 403(b)s is a quirk that most general practitioners (financial advisors, not just tax preparers) miss. Get specialized advice. The retirement contribution capacity available to a physician with proper structure can exceed $200K per year — well worth the planning.

Non-profit restructurings and mergers happen more often than you’d think — hospital systems merge, universities consolidate operations, charities absorb other charities. The 403(b) participant in a restructuring scenario faces several specific risks that are different from the 401(k) participant in a private-sector M&A transaction. Let me work through both your direct concerns and the protections available.

The baseline protection: ERISA fiduciary duty.

If your 403(b) is an ERISA plan (most 501(c)(3) hospital and large non-profit 403(b)s are), the plan fiduciary has a §404 duty of prudence and loyalty. Restructurings and mergers don’t suspend this duty. The fiduciary must continue to operate the plan in participants’ interests even during the corporate transaction.

This protection mirrors the 401(k) ERISA protection. Both ERISA plans (401(k) and ERISA 403(b)) have the same fiduciary standard.

If your 403(b) is a non-ERISA plan (governmental, church, or DOL safe harbor), no ERISA fiduciary duty applies. State law governs. Protections vary.

Vesting protection.

Under §411(d)(3), a plan termination or partial termination causes immediate 100% vesting of all employer contributions. If the restructuring results in significant layoffs or plan termination, your unvested employer contributions become fully vested.

Definition of ‘partial termination.’ If more than 20% of plan participants are involuntarily terminated within a specific timeframe (typically one plan year), the IRS considers it a partial termination. All affected employees vest 100%. SECURE Act §209 provided pandemic-era relief expanding the testing period but the basic 20% threshold remains.

This is the same in 401(k) and 403(b). Same statute (§411) applies to both.

Plan continuation vs. termination.

In a merger, the acquiring entity has options:

Option A: continue the existing 403(b). The plan continues unchanged, just with the new entity as sponsor. Most common.

Option B: merge the existing 403(b) into the acquirer’s plan (a 403(b) or 401(k)). Participants’ balances transfer to the acquirer’s plan. Investment options may change. Contribution rates may need updating.

Option C: terminate the existing 403(b). Distributes balances to participants. Participants must roll over or take distributions. SECURE 2.0 expanded the auto-rollover rules ($7,000 threshold).

If your plan is terminated, you’ll receive the full vested balance. You can roll to an IRA tax-free under Notice 2014-54 with after-tax basis isolation if applicable. Most participants roll to traditional IRA + Roth IRA (if Roth balance) at Fidelity, Schwab, or Vanguard.

The 403(b) successor plan rule under Treas. Reg. 1.403(b)-10. If a 403(b) is terminated, the sponsor cannot establish a new 403(b) within 12 months. This protects participants from sham terminations designed to force distribution. The 401(k) doesn’t have this exact rule but has similar successor plan protections under §401(k)(10)(A).

Legacy annuity contract handling.

This is the 403(b)-specific risk. If you have funds in legacy annuity contracts (the older 403(b)(1) annuity-only contracts), the contract terms control during a plan termination. Surrender charges may apply. Annuity contracts can be ‘in-service distributable’ (you receive the contract; it converts to an individual annuity in your name) or ‘in-plan terminated’ (the contract holder is required to distribute the cash value).

Legacy annuity contract terms vary widely. Some have 10-year declining surrender charges. Some have market-value adjustments. Some have annuitization options that lock in below-market interest rates. Read the contract before agreeing to any plan-termination-driven distribution.

Prior 403(b) restructurings have seen participants forced into low-interest annuitization because the contract didn’t allow surrender during the relevant window. Lost income compared to direct rollover.

The 401(k) doesn’t have this complication. 401(k) plans hold mutual fund shares or other liquid investments; distributions are uncomplicated.

ERISA Section 502 lawsuits.

If the fiduciary breaches duty during a restructuring (selecting a high-fee receiving plan, mishandling contracts, taking excessive fees from the transaction), participants can sue under ERISA §502. Class action lawsuits during corporate transitions are common.

Non-ERISA 403(b) participants have no equivalent. State law remedies are limited.

Form 5500 filings during restructuring.

The plan must file a final Form 5500 in the year of plan termination. The form discloses asset transfers, distributions, and remaining obligations. The DOL reviews the filing for compliance.

ERISA 403(b) Form 5500: filed at efast.dol.gov, publicly accessible. You can verify your former plan’s termination was reported.

Non-ERISA 403(b): no Form 5500 filing. Verification is more difficult.

What to watch for during restructuring.

1. Plan termination notice. Required under ERISA. You must receive written notice of plan termination and your rollover/distribution options at least 30 days before action.

2. Distribution timeline. Once distributions are processed, you typically have a tight window (often 60-90 days) to direct rollover destinations. Default treatment may be cash distribution with 20% mandatory withholding — to be avoided.

3. Plan document changes. If the plan is merged or amended, get the new plan document. Read it. Some merged plans have less generous match formulas or different vesting schedules going forward.

4. Investment menu changes. If your existing investments aren’t available in the new plan, you’ll be defaulted into similar investments or asked to make active selections. Review and adjust.

5. Recordkeeper changes. Your new recordkeeper portal may be different. Set up new login. Verify balances transferred correctly.

6. Loan handling. If you have an outstanding plan loan, plan termination or transfer can accelerate the loan repayment. Default on the loan converts the balance to a deemed distribution subject to §72(t).

7. Pre-tax/Roth balance tracking. Both pre-tax and Roth designated balances should transfer with their characteristics intact. The 5-year Roth holding clock continues. Verify the new recordkeeper recognizes your pre-tax vs. Roth split.

8. Loan repayment status. If you have an outstanding loan, the merger or termination may accelerate repayment. Negotiate with the plan administrator if you can’t repay.

9. Beneficiary designations. Most plan mergers preserve beneficiary designations, but verify after transfer.

Protective actions to take.

A. Get the plan document and amendments. Read the termination provisions. Confirm the IRS-required vesting acceleration if applicable.

B. Document your account balance at the point of the transaction. Pre-tax balance, Roth balance, investments, beneficiary designations. Take screenshots of the recordkeeper portal.

C. Coordinate with your tax preparer. Plan termination and rollover decisions interact with your overall tax situation. Don’t make decisions without consulting.

D. Direct rollover only. Don’t take a check; do trustee-to-trustee transfer. Avoid the 20% mandatory withholding.

E. After-tax basis isolation. If you have after-tax basis (rare in 403(b)s, common in 401(k)s with after-tax contribution provisions), use Notice 2014-54 to roll after-tax to Roth IRA and pre-tax to traditional IRA.

F. Consider in-service distribution before termination. Some plans permit in-service distributions for participants past age 59.5. If you’re eligible, taking a partial in-service distribution before termination may give you more control over timing.

G. Consult an ERISA attorney if you suspect fiduciary breach. Most ERISA attorneys offer free consultations. If a plan termination appears mishandled, the lawyer can evaluate the case.

Key differences between 403(b) and 401(k) protection during restructuring.

Similarities: vesting acceleration, fiduciary duty (if ERISA), rollover availability, 20% withholding rules.

Differences: 403(b) has legacy annuity contract complications; 401(k) doesn’t. 403(b) has successor plan 12-month restriction; 401(k) successor plan rules different. 403(b) has Roth match optional under SECURE 2.0 §604; same for 401(k). Both are subject to QDRO in divorce.

Non-ERISA 403(b) participants face the biggest risk: no fiduciary protection, no Form 5500 transparency, no §502 lawsuit standing.

If you’re in a non-ERISA 403(b) during a restructuring, you need to be especially diligent. Document everything. Get the plan document. Track balances at each step. State consumer protection laws may apply if there’s misconduct.

Bottom line for your specific concern.

403b vs 401k tax treatment during restructuring is essentially identical for ERISA plans (same fiduciary duty, same vesting rules, same rollover options). The 403(b) participant has additional complications around legacy annuity contracts and (if non-ERISA) loss of fiduciary protection. The 401(k) participant has cleaner mechanics but the same statutory protections.

Watch the timeline and the contract terms closely. Get help if anything looks irregular. The Reed Corporation has handled many post-restructuring rollovers — the process is standard but the details matter.

Final piece of practical advice: don’t panic. Plan terminations and mergers happen routinely. The protections in place generally work. Most participants come through restructurings with their balances intact. The risks are real but manageable with attention to detail.

Two-income married couples with mixed public/private retirement plan access have one of the strongest planning opportunities in the tax code, and the differences between 403(b)/457(b) on her side and 401(k) on yours matter for how to structure the household contribution plan. Let me work through this systematically.

Total household contribution capacity for 2026.

Her plans (teacher): – 403(b): $24,500 deferral + $8,000 age-50 catch-up = $32,500 – 457(b): $24,500 deferral + $8,000 age-50 catch-up = $32,500 – 403(b) and 457(b) limits don’t aggregate – Her total elective deferral capacity: $62,000

Your plan (private sector): – 401(k): $24,500 deferral + $8,000 age-50 catch-up = $32,500 – Your total elective deferral capacity: $31,000

Combined household elective deferral capacity: $62,000 + $31,000 = $93,000.

At your combined income of $220K, that’s 42% of gross. Aggressive but achievable if other expenses are manageable.

Add employer match contributions on top. Most teachers’ 403(b)s don’t have match; most private 401(k)s do. Your employer’s match (assume 50% match on up to 6% of pay) on $135K = $4,050 if you contribute at least 6%. Combined household additions including match: $97,050.

§402(g) aggregation question. The 401(k) and 403(b) limits aggregate across plans for a single participant, but they don’t aggregate across spouses. You and she each have your own §402(g) limit. So she can max her 403(b) at $31,000 and you can max your 401(k) at $31,000 independently. The aggregation is per-participant, not per-household.

The contribution priority order across your household.

Step 1: Capture all available employer matches first. Free money.

Your 401(k) match: contribute enough to get the full match. At 6% of $135K with 50% match = $4,050 match. You contribute $8,100 of your own.

Her 403(b) and 457(b) matches (if any). Most public school districts don’t match the 403(b). The 457(b) usually doesn’t have match. Confirm at her district.

Step 2: Fill the 457(b) before the other plans. Her 457(b) has the most flexibility — no §72(t) early withdrawal penalty at any age. If she leaves teaching before 59.5, the 457(b) gives her penalty-free access. Max it.

Her 457(b) max: $31,000.

Step 3: Fill the 401(k) on your side (after match captured). The 401(k) has standard age-55 separation exception under §72(t)(2)(A)(v), so if you separate at 55 or later, you have penalty-free access. Otherwise wait until 59.5.

Your 401(k) max: $31,000.

Step 4: Fill the 403(b) on her side. The 403(b) has age-55 separation exception (same as 401(k)). Use any remaining capacity.

Her 403(b) max: $31,000.

Step 5: After all employer plan capacity is used, consider IRA contributions. If your AGI is below the IRA deduction phase-out limits, you and she can each contribute $7,000 to traditional IRAs ($8,000 with age-50 catch-up). At $220K combined income and active in employer plans, your IRA deduction is phased out. Roth IRA contribution phase-out for married filing jointly is $246K-$256K for 2026, so you may still qualify for Roth.

If Roth IRA is available, prioritize that over additional taxable savings.

Maximum aggressive scenario for 2026: – His 401(k): $31,000 – Her 403(b): $31,000 – Her 457(b): $31,000 – Roth IRA backdoor (if AGI permits): $7,000 each × 2 = $14,000 – Total: $107,000

At $220K income, $107,000 is 49% saved into tax-advantaged accounts. Most couples can’t do this; it requires significant lifestyle restraint and probably no kids or paid-off house. But the capacity is there if affordable.

More realistic scenario: $60-70K of total contributions.

Traditional vs. Roth across the household.

Your combined income of $220K puts you in the 24% federal bracket. Marginal rate on additional income: 24%. State varies; assume 5-7% combined.

In retirement, with her teacher pension (assume 60% of final salary = $51K), Social Security (roughly $30K each = $60K combined), and retirement account distributions, your retirement income will likely be $150K-$180K. Federal bracket: 22-24% depending on exact income and bracket structure in retirement years.

For most couples in your bracket, retirement marginal rate is similar to or slightly lower than current marginal rate. Traditional contributions are slightly better than Roth (immediate deduction at 24% > future Roth withdrawal taxed at 22-24%). But the difference is small.

If you expect retirement income higher than current (high earner trajectory, large inheritance, etc.), lean Roth. If you expect retirement income lower than current (early retirement, modest portfolio), lean traditional.

For her 403(b) and 457(b), most public school districts now offer Roth. Confirm.

For your 401(k), almost all private plans offer Roth. Confirm.

The SECURE 2.0 §603 high-earner Roth catch-up. You at $135K are under the $145-160K threshold (which is indexed but uncertain for 2026). She at $85K is well under. Neither of you is forced into Roth catch-up. You have discretion.

The age-55 catch-up dynamics.

You’re 55 now. The age-50 catch-up of $8,000 applies to both of you for 2026. The age 60-63 super catch-up will apply starting age 60 (5 years away). At ages 60-63, the catch-up increases to $11,250.

Projection: at age 60, each of your contribution limits increases. Plan to ramp up contributions then if income permits.

State tax considerations.

If you’re in a high-tax state (California, NY, NJ, MA, OR), pre-tax contributions reduce state taxable income meaningfully. State tax savings on $90K of pre-tax contributions at 7% state rate = $6,300/year.

If you plan to retire to a no-tax state (Florida, Texas, Nevada, Tennessee, Washington), Roth contributions become especially attractive — you pay the high-tax-state income tax now on Roth contributions, then withdraw tax-free in the no-tax state. This is a meaningful planning lever.

If staying in current state through retirement, the state tax differential is less important.

Investment menu comparison.

Get the investment menus from all three plans (your 401(k), her 403(b), her 457(b)). Calculate weighted expense ratios.

A good 401(k) has weighted expense ratio under 0.20%.

Most ERISA 403(b)s are similar.

Non-ERISA 403(b)s (public school) can have higher fees — 0.50-1.50%.

457(b)s can vary widely.

If one plan has materially higher fees than the others, weight contributions toward the lower-fee plans (after capturing match in all). Long-term wealth difference can be substantial.

Catch-up specifics for each plan.

Her 403(b): age-50 catch-up of $7,500 + potential 15-year catch-up if she has 15+ years at her current district. The 15-year catch-up is calculated as the least of $3,000, $15,000 – prior amounts, or $5,000 × years of service – prior deferrals. Probably doesn’t apply if she’s been contributing consistently, but check.

Her 457(b): age-50 catch-up of $7,500. Also a ‘final 3-year catch-up’ under §457(b)(3) — for participants within 3 years of normal retirement age, the limit doubles to $47,000 (2× the basic limit). She can’t use both age-50 and final-3-year catch-ups in the same year (must elect one). At age 55, she’s probably not yet within 3 years of normal retirement, so age-50 catch-up applies.

Your 401(k): age-50 catch-up of $7,500. No other catch-ups available.

Withdrawal flexibility comparison.

457(b): no §72(t) penalty at any age. Most flexible.

403(b): §72(t) applies but age-55 separation exception available.

401(k): §72(t) applies but age-55 separation exception available.

The 457(b)’s no-penalty access is the biggest advantage for couples who might retire early. If she leaves teaching at 57, her 457(b) provides bridge income to 59.5 without the 10% penalty.

Beneficiary planning.

Both of you should be each other’s primary beneficiary on all three plans. Contingent beneficiaries (children, parents) should be specified.

Surviving-spouse treatment of inherited retirement plans is favorable. The surviving spouse can roll to own IRA, deferring distributions. Compared to non-spouse beneficiaries who face the 10-year SECURE Act window.

Roth designated balances. If one or both of you hold Roth balances at death, the surviving spouse can roll to a Roth IRA. The 5-year clock continues from the original first-Roth-contribution date.

Final recommendation for your household:

1. Determine total household savings capacity. Probably $60-90K depending on cash flow.

2. Allocate to plans in this order: a. Capture all employer matches b. Fill her 457(b) (most flexible) c. Fill her 403(b) (or alternate with yours based on plan quality) d. Fill your 401(k)

3. Mix traditional and Roth based on tax bracket expectations. Probably 70% traditional, 30% Roth for your bracket.

4. Reassess annually as limits change and your income evolves.

5. At age 60 (5 years out), capture the super catch-up if affordable.

For 403b vs 401k tax treatment across your dual-employer household, the 403(b)/457(b) combination on her side gives more total deferral capacity than her 401(k) alone would. The 401(k) on your side is comparable to her 403(b) in mechanics — the differences are mostly about plan-specific match formulas, investment options, and Roth availability. Combined, your household has nearly $100K of annual deferral capacity, which is more than most dual-401(k) couples can achieve. Make the most of it.

The Reed Corporation helps couples in this situation map the contribution allocation each year. The annual limits change, the IRS issues new guidance, and the plan options at your employers may evolve. Worth an annual review.

Rollover decisions at job separation are often the most consequential single financial decision of a career — you’re moving 12 years of savings, and the rollover choices have multi-decade tax implications. Let me work through the strategy systematically.

The basic options.

Option A: Leave the 403(b) and 457(b) in place at the hospital. Many plans permit former employees to maintain accounts. Continued investment management at the hospital’s plan vendor.

Option B: Roll the 403(b) and 457(b) to a traditional IRA. Most common choice. Provides broader investment menu and direct beneficiary control.

Option C: Roll to a new employer’s plan (if you’re starting a new job with a 401(k) or 403(b)). Useful for ongoing plan loan availability and ERISA protection.

Option D: Roll to a Roth IRA (taxable conversion). Pay income tax now; future growth tax-free.

Option E: Take a distribution. Lump-sum distribution with full income tax due. Generally the worst choice unless you actually need the funds.

Let me work through the specifics of each.

Option A: Leave it in place.

Pros: – ERISA protection continues (if ERISA 403(b)) – §72(t) age-55 separation exception applies — at 58, you have penalty-free access to the 403(b) (and to the 457(b), which never had §72(t)) – Continued investment management at familiar vendor – May avoid certain fees from rollover transactions

Cons: – Limited investment options (the plan’s menu) – Plan-specific rules on distributions (some plans require lump sum at separation; others permit installments) – Beneficiary planning complications (plan beneficiary rules may differ from IRA rules) – Plan can be terminated or restructured in the future (losing your continued access) – Often higher fees than self-directed IRA at major custodian

Verdict: Option A makes sense if you’re confident in the plan’s quality and want to preserve age-55 access. But at 58, you’ll qualify for age-59.5 in 1.5 years, so the §72(t) advantage isn’t decisive. For most situations, rolling to IRA is better.

Option B: Roll to traditional IRA.

Pros: – Broader investment options (any custodian, any mutual fund, ETFs, individual stocks) – Lower fees at major custodians (Fidelity, Vanguard, Schwab) than most plan recordkeepers – Direct beneficiary control (you specify beneficiaries on the IRA, not through plan rules) – Consolidated account management – QCD availability after age 70.5 (Qualified Charitable Distributions up to $108,000/year)

Cons: – Loss of age-55 separation exception (rolled to IRA, all distributions before 59.5 are subject to §72(t) unless other exception applies) – Loss of plan loan availability (IRAs can’t have loans; only plans can) – ERISA protection ends (IRA is governed by state law, not ERISA) – Pro-rata rule for backdoor Roth contributions (if you make non-deductible IRA contributions, the rule complicates them)

Verdict: Option B is the right default for most rollovers. At 58, the age-55 exception is only marginally useful (1.5 years to 59.5). The investment flexibility and cost savings dominate.

Option C: Roll to a new employer’s plan.

Pros: – Maintain ERISA protection – Plan loan availability – Age-55 separation exception preserved (if you separate from new employer at age 55+) – Backdoor Roth eligibility (no pro-rata rule from IRA balances)

Cons: – Limited to the new plan’s investment menu – May require waiting period (some plans don’t accept rollovers from new employees until after 1 year) – Recordkeeper transition complications

Verdict: Option C makes sense if you’re starting a new job and want to maintain plan-level benefits. Especially useful for backdoor Roth users — keeping pre-tax balances out of IRAs simplifies the backdoor Roth.

Option D: Roth conversion.

Pros: – Future growth tax-free – No future RMDs (Roth IRAs have no lifetime RMDs) – Tax-efficient wealth transfer to non-spouse beneficiaries (Roth follows 10-year rule with no income tax)

Cons: – Immediate tax cost on the converted amount – Bracket impact in conversion year – Once converted, can’t be undone (no recharacterization since 2018)

Verdict: Option D makes sense for partial amounts in specific bracket-management scenarios. For most participants, converting the entire $480K + $90K = $570K in one year is too much — the tax bill (probably 30-35% federal + state) is enormous.

My specific recommendation for your situation.

Step 1: Roll the 403(b) to a traditional IRA at Fidelity, Schwab, or Vanguard.

The 403(b) at $480K is large enough to benefit from broader investment options and lower fees. The age-55 separation exception applies until age 59.5; you’re 58, so 18 months of penalty-free access remains. The rollover to IRA gives up that exception, but you can take distributions from the 403(b) before the rollover if you need access during the 18-month window.

Do a trustee-to-trustee direct rollover. Form 1099-R from the hospital plan with code G. No withholding. Form 5498 from the IRA custodian reports the rollover deposit.

Step 2: Roll the 457(b) to a traditional IRA at the same custodian.

The 457(b) is more complicated. Some 457(b) plans don’t permit direct rollovers to IRAs and instead require lump-sum distribution at separation. Check the plan document. If direct rollover is permitted, do it.

The 457(b) loses its no-§72(t)-penalty advantage when rolled to an IRA. If you might need pre-59.5 access to the $90K, consider leaving it in the 457(b). At 58, the value of this is limited (18 months to 59.5), but if you have other expense needs, the flexibility matters.

Step 3: Roth conversion strategy.

With $570K of new traditional IRA balances at age 58, you have flexibility on future Roth conversions. Strategy:

Year 1 (current year of separation): convert $50K-$100K to Roth IRA. Stays in lower brackets (24% federal). Add to your existing income at separation.

Years 2-10 (ages 59-67): continue annual Roth conversions of $50K-$100K. The Tax Cuts and Jobs Act brackets are scheduled to expire end of 2025, with higher brackets resuming 2026 onward (unless extended). Convert aggressively during low-bracket years.

Years 11+ (age 68+): scale back conversions; the conversion benefit is reduced as bracket and life expectancy both shorten.

The Roth conversion strategy can move 30-50% of your traditional balance to Roth over a 10-year period, at total tax cost of perhaps $150K-$200K. Compared to leaving everything traditional and taking RMDs starting at 73, the conversion saves estate-level taxes for your beneficiaries (who would otherwise face 10-year window taxes at their potentially higher brackets).

Step 4: 5-year holding rule planning.

Roth IRA qualified distributions require 5 years from first Roth IRA contribution (or conversion) and age 59.5. The 5-year clock counts from January 1 of the first year of any Roth IRA you own — not separately for each conversion.

Start the clock now. If you don’t have a Roth IRA, open one and make any contribution (even $10) to start the 5-year clock for the entire Roth ecosystem.

For specific conversion 5-year rule (separate from the general one): each conversion has its own 5-year clock for purposes of the 10% penalty on the converted amount if withdrawn early. Since you’re 58 now and will be 63 at year 5, this isn’t a practical concern.

Step 5: Avoid the common mistakes.

Mistake 1: Indirect rollover. Don’t take a check made out to you. The 20% mandatory withholding on indirect rollovers is a trap. To complete the rollover, you’d need to deposit the withheld amount from other funds within 60 days. Always do trustee-to-trustee direct rollover.

Mistake 2: Mixing pre-tax and after-tax in rollover. If you have any after-tax basis in the 403(b) (rare but possible), the rollover should separate the basis to Roth IRA and the pre-tax to traditional IRA under Notice 2014-54. Verify with the plan administrator whether any after-tax basis is in your account.

Mistake 3: Forgetting beneficiary updates. The new IRA needs beneficiary designations. Don’t assume your plan beneficiary designations transfer — verify on the IRA account paperwork.

Mistake 4: Cashing out for emergency funds. Some people withdraw retirement balances to fund post-separation transitions. At your $570K balance, taking $50K-$100K to cover transition costs would cost 30-40% in immediate tax. Use emergency savings or HELOCs first; preserve retirement balances.

Mistake 5: Premature Roth conversion of full balance. Don’t try to convert all $570K in one year. Spread conversions over multiple years to manage brackets.

Mistake 6: Not coordinating with Social Security. Roth conversions affect provisional income for Social Security taxability. At your age, you may not yet be receiving SS, but planning for SS claiming at 62-70 should factor in.

Mistake 7: Missing state tax planning. If you’re moving states (common at retirement), time the rollover and conversion to occur after the move if moving to a no-tax state, or before the move if you have residual concerns. State residency is established by physical presence and intent.

Step 6: Investment allocation in the new IRAs.

At 58 with retirement potentially within 5 years, traditional advice suggests reducing equity allocation. But you may have 30+ years of retirement; staying aggressive longer makes sense.

Reasonable allocation: 60% equity / 40% bonds. Adjust based on risk tolerance and other assets.

Index funds at low expense ratios. Vanguard Total Stock Market (VTSAX, expense ratio 0.04%), Vanguard Total International Stock (VTIAX, 0.11%), Vanguard Total Bond Market (VBTLX, 0.05%).

For 403b vs 401k tax treatment at separation, your specific 403(b) + 457(b) combination has unique advantages (the 457(b) flexibility) but most rollover mechanics are similar to a 401(k). The strategy: direct rollover both to IRA, plan Roth conversions over 10 years, manage brackets carefully, avoid the common mistakes.

The Reed Corporation regularly handles rollover planning for separating non-profit employees. The decisions you make at separation echo for 30+ years. Get it right the first time.

Final note: don’t rush. You have 60 days from any indirect rollover (avoid this) or no time limit on direct rollover. Take 30-60 days to plan the rollover properly. Run multi-year tax projections. Coordinate with your CPA. Document all decisions in writing for future reference.
