Quick Answer
2026 contribution limits:
- 401(k) deferral: $23,500 (up from $23,000 in 2025)
- 403(b) deferral: $23,500 (same as 401k)
- Catch-up (age 50+): +$7,500 = $31,000 total
- Employer match: Typically 3–6% (not capped, but total 401k is capped at $69,000)

2026 Contribution Limits by Account Type
401(k) Plans
| Limit | 2026 Amount | Who | Notes |
|---|---|---|---|
| Employee deferral | $23,500 | Everyone | Pre-tax (reduces taxable income) |
| Catch-up (age 50+) | $7,500 | Age 50+ | Additional amount |
| Total employee (age 50+) | $31,000 | Age 50+ | Combined |
| Employer match (combined limit) | Included in $69,000 | Employer | Typical 3–6% |
| Total contribution limit | $69,000 | Everyone | Employee + employer combined (age <50) |
| Total (age 50+ with catch-up) | $76,500 | Age 50+ | Includes catch-up |
403(b) Plans (Nonprofit/Education)
Identical to 401k:
- Employee deferral: $23,500
- Catch-up (age 50+): +$7,500 = $31,000
- Total (with employer): $69,000–$76,500
Exception: 403(b) plans have a special "15-year employee" catch-up (up to $3,000/year for eligible participants). Rarely used but worth knowing.
Traditional and Roth IRA
| Account | 2026 Limit | Catch-up (50+) | Notes |
|---|---|---|---|
| Traditional IRA | $7,000 | +$1,000 = $8,000 | Pre-tax; lowers taxable income |
| Roth IRA | $7,000 | +$1,000 = $8,000 | Post-tax; tax-free growth |
| Backdoor Roth | $7,000 | +$1,000 = $8,000 | Non-deductible IRA → Roth conversion |
Note: IRAs are separate from 401k/403b. You can max both in the same year.
HSA (Health Savings Account)
| Type | 2026 Limit | Catch-up (55+) | Notes |
|---|---|---|---|
| Self-only coverage | $4,300 | +$1,400 = $5,700 | Requires high-deductible plan |
| Family coverage | $8,600 | +$1,400 = $10,000 | Entire family covered |
HSA is triple tax-advantaged: Contributions deductible, growth tax-free, withdrawals for medical expenses tax-free.
Real Physician Contribution Strategy (2026)
Scenario: Dr. Chen, Age 45, Employed at Hospital, Earns $300,000
Available retirement plans:
- 401(k) with 6% employer match
- Roth IRA
Maximum tax-deferred contribution strategy:
| Account | Contribution | Notes |
|---|---|---|
| 401(k) employee deferral | $23,500 | Automatic from paycheck |
| 401(k) employer match | $18,000 (6% of salary) | Employer contribution |
| Backdoor Roth IRA | $7,000 | Convert non-deductible IRA |
| After-tax 401(k) (if allowed) | $20,500 | Remainder to $69K limit (mega backdoor) |
| HSA (if high-deductible plan) | $8,600 (family) | Triple tax advantage |
| Total tax-deferred | $77,600 | Invested pre-tax |
Tax savings (at 37% marginal rate):
- $77,600 × 37% = $28,700 in federal taxes saved
- Plus state taxes (CA example): $77,600 × 9.3% = $7,217 additional state tax savings
- Total annual tax savings: $35,917
Scenario: Dr. Rodriguez, Age 55, Solo Practice Owner, Earns $350,000
Available retirement plans:
- Solo 401(k) (self-employed)
- Solo Roth IRA (self-employed)
- SEP-IRA alternative
Maximum contribution strategy (Solo 401k):
| Contribution | Amount | Notes |
|---|---|---|
| Employee deferral | $31,000 | Includes $7,500 catch-up (age 50+) |
| Employer contribution (approx) | $40,000 | ~20% of net self-employment income |
| After-tax/mega backdoor | $5,000 | Remainder to ~$76,500 limit |
| SEP-IRA alternative | $40,000 | Or instead of Solo 401k |
| Total tax-deferred | $76,000 | Compare Solo 401k vs SEP |
Advantage of Solo 401(k): Mega backdoor Roth option + more flexibility than SEP-IRA.
Limits by Income (What You Can Contribute)
High-Income Physician ($300K+)
You can max out:
- 401(k) deferral: $23,500 ✅
- Employer match: $15,000–$20,000 ✅
- Backdoor Roth: $7,000 ✅
- HSA: $8,600 ✅
- Mega backdoor: $20,000–$25,000 ✅
- Total: $74,000–$84,000/year tax-deferred
Income limit check: No income limit for 401k. Roth IRA has income phase-out (married $240K+, single $160K+), so use backdoor Roth instead.
Mid-Income Physician ($150K–$250K)
You can max out:
- 401(k) deferral: $23,500 ✅
- Employer match: $10,000–$15,000 ✅
- Backdoor Roth: $7,000 ✅
- HSA: $8,600 ✅
- Mega backdoor: $10,000–$15,000 (if available) ✅
- Total: $59,000–$69,000/year
Early Career ($80K–$150K)
You can max out:
- 401(k) deferral: $23,500 ✅
- Employer match: $5,000–$9,000 ✅
- Backdoor Roth: $7,000 ✅
- HSA: $8,600 ✅
- Mega backdoor: Limited or unavailable ❌
- Total: $44,000–$48,000/year
Catch-Up Contributions (Age 50+)
At age 50, you become eligible for additional "catch-up" contributions:
401(k) Catch-Up
Additional $7,500 allowed:
- Normal limit: $23,500
- With catch-up: $31,000
- Applies to all plan types: 401(k), 403(b), 457(b)
IRA Catch-Up
Additional $1,000 allowed:
- Normal limit: $7,000
- With catch-up: $8,000
- Applies to Traditional and Roth IRA
HSA Catch-Up
Additional $1,400 allowed (age 55+):
- Normal limit: $4,300 (self-only) / $8,600 (family)
- With catch-up (age 55+): $5,700 (self-only) / $10,000 (family)
Strategy: If you reach age 50 and haven't maxed retirement, this is your chance to catch up. The extra $7,500 × 15 years to age 65 = $112,500 at 7% growth becomes $212,000 additional retirement wealth.
Income Phase-Outs and Limits
Roth IRA Income Phase-Out (2026)
| Filing Status | Phase-Out Begins | Fully Phases Out | Contribution |
|---|---|---|---|
| Single | $146,000 | $161,000 | Full at <$146K |
| Married Filing Jointly | $230,000 | $240,000 | Full at <$230K |
| Married Filing Separately | $0 | $10,000 | Nearly always phases out |
For most physicians: Use backdoor Roth instead (no income limit).
401(k) Deferral — No Income Limit
You can contribute the full $23,500 regardless of income. No phase-out.
Employer Match — No Limit
Employers can contribute any amount to 401(k) as long as total (employee + employer) doesn't exceed $69,000 (age <50) or $76,500 (age 50+).
Common Mistakes Physicians Make
❌ Mistake 1: Only contributing to 401k employer match, not maxing out ✅ Fix: Max your deferral ($23,500) first, get match, then mega backdoor.
❌ Mistake 2: Trying to contribute to a Roth IRA at high income and getting rejected ✅ Fix: Use backdoor Roth conversion instead (no income limit).
❌ Mistake 3: Not understanding that 401k and IRA limits are separate ✅ Fix: Max both: $23,500 in 401k + $7,000 in Roth IRA = $30,500 total.
❌ Mistake 4: Forgetting to do mega backdoor Roth because "it's complicated" ✅ Fix: Your plan administrator can handle it. Ask HR; takes 1 call.
❌ Mistake 5: Ignoring HSA as investment account ✅ Fix: HSA is "stealth IRA" — triple tax advantage. Max it for investment, not just medical expenses.
Step-by-Step 2026 Contribution Checklist
- Determine which retirement plans you have access to: 401k? 403b? Solo 401k?
- Calculate your income and check Roth IRA eligibility. (If phased out, plan backdoor Roth.)
- Set up 401k payroll deduction to max out: $23,500 ÷ 26 paychecks = ~$904/paycheck.
- Confirm employer match % and set enough deferral to capture it all.
- Ask HR: Does your 401k allow after-tax contributions and in-plan Roth conversions? (For mega backdoor.)
- Maximize HSA if on high-deductible plan ($8,600 for family).
- If self-employed, set up Solo 401k or SEP-IRA by Dec 31.
- Plan backdoor Roth for late December or early January (easier for tax time).
- Review Year-End: Did you reach contribution targets? Adjust for next year if needed.
- Use the physician retirement planner to model long-term impact of max contributions.
Frequently Asked Questions
Q: Can I contribute $69,000 every year? A: Yes, if employer and employee contributions fit. Employee deferral is capped at $23,500; employer + employee combined cannot exceed $69,000 (age <50).
Q: What happens if I over-contribute? A: Excess contributions are taxable in the year of over-contribution. The plan administrator will notify you; you can request a refund (taxable plus 6% penalty on gains).
Q: Can I contribute to a 401k and a Solo 401k in the same year? A: Yes. You can have a W-2 401k and a Solo 401k from self-employment income. Total limits apply across all plans, but common for physicians with side income.
Q: If I max my 401k in October, can I stop payroll deductions? A: Yes, but confirm with payroll. You can reduce to zero once you've hit the limit.
Q: Do catch-up contributions count toward the $69,000 limit? A: Yes. Total ($69,000 age <50; $76,500 age 50+) includes catch-up contributions.
Q: Is there a contribution deadline? A: 401k contributions must be made by December 31 of the year. Self-employed plans (Solo 401k) must be established by Dec 31, but funding can occur until April 15 of the following year (with extension).
Q: Should I defer the full $23,500 or take a paycheck? A: If you're high-income, deferring reduces your taxable income and taxes. Deferring is almost always better than taking cash (unless you need cash flow). Model both scenarios.
Q: How much should I contribute if I'm unsure? A: At minimum, contribute enough to capture 100% of employer match (free money). Then max out as income allows.
