What is a 403(b) plan?
- A 403(b) is a tax-advantaged retirement plan for employees of public schools, 501(c)(3) nonprofits, and certain ministers and church employees.
- Employees defer salary pre-tax or as Roth; for 2026 the elective deferral limit is $24,500, the same as a 401(k).
- Investments are limited to insurance annuity contracts or mutual funds held in a 403(b)(7) custodial account.
- Pre-tax withdrawals are taxed as ordinary income, generally with a 10% additional tax before age 59½ unless an exception applies.
How is a 403(b) different from a 401(k)?
- For 2026 both allow a $24,500 deferral, an $8,000 age-50 catch-up, and a larger $11,250 catch-up for ages 60 through 63.
- Many governmental and church 403(b) plans are exempt from ERISA, so plan-level fee oversight and disclosure can be thinner than in a typical 401(k).
- Public-school plans often approve many vendors, leaving participants to compare insurance and fund products with little plan-level screening.
- Employee plus employer additions are capped at $72,000 for 2026 under the §415(c) limit, not counting catch-up contributions.
How does the 403(b) 15-year catch-up work?
- Employees with 15 or more years at a qualifying school, hospital, church, or similar organization may add up to $3,000 a year, with a $15,000 lifetime cap.
- Eligibility shrinks if past deferrals averaged $5,000 or more a year, and the plan document must offer the feature.
- It can be combined with the age-50 catch-up, but the ordering math is technical, so confirm your figure with the plan administrator or a CPA.
- Starting in 2026, employees whose prior-year FICA wages from the employer exceeded $150,000 must make age-50 catch-ups as Roth contributions.
What investments are offered, and what do they cost?
- 403(b)(1) annuity contracts can carry mortality and expense charges, rider fees, and surrender charges that last several years.
- 403(b)(7) custodial accounts hold mutual funds, which may include low-cost index funds depending on the vendor.
- Because fee disclosure varies in non-ERISA plans, asking each vendor for total annual cost and any surrender schedule is worthwhile.
- Plans may permit exchanges between approved vendors, but leaving an annuity contract early can trigger surrender charges.
Roth 403(b) options and employer vesting
- Many plans offer a Roth 403(b): contributions are after-tax, qualified withdrawals are tax-free, and there is no income limit to participate.
- Since 2024, Roth 403(b) balances are not subject to required minimum distributions during the original owner's lifetime.
- Nonprofits more often make matching contributions than public school districts, which frequently rely on a pension instead.
- Employer contributions in ERISA plans can vest on up to a three-year cliff or six-year graded schedule; your own deferrals are always fully vested.
Pairing a 403(b) with a 457(b)
- Many public-school and state employees can also contribute to a governmental 457(b), which has its own separate $24,500 limit for 2026.
- Governmental 457(b) withdrawals after separation are not subject to the 10% early-distribution tax, unlike most 403(b) money before 59½.
- Using both roughly doubles deferral room, but whether that fits depends on cash flow, tax bracket, and pension coverage.
Key takeaways
- A 403(b) matches a 401(k) on 2026 contribution limits but differs on investment vehicles, ERISA coverage, and vendor structure.
- The 15-year catch-up and a companion 457(b) can add deferral room for long-tenured public and nonprofit employees.
- Annuity-based options can carry layered fees and surrender charges, so compare total costs before contributing or transferring.
- Catch-up and Roth rules changed for 2026; confirm your eligibility with your plan administrator and a CPA.
