NYSTRS 403(b) and 457 Plans: How Supplemental Savings Work With Your Pension

Your NYSTRS pension is a defined benefit — a guaranteed monthly payment calculated from your service and salary. But most educators also carry a 403(b), a 457(b), or both. These supplemental accounts play by entirely different rules, and understanding how they interact with your pension matters more than most people realize at retirement time.

403(b) and 457(b) Are Separate From Your NYSTRS Pension

Neither a 403(b) nor a 457(b) affects your NYSTRS benefit calculation. Your pension is based on your tier, years of credited service, and Final Average Salary. Contributions to supplemental accounts do not increase or decrease your pension.

The accounts are managed by private providers selected by your school district — TIAA, Fidelity, Vanguard, or others on the district's approved vendor list. NYSTRS has no role in administering these accounts.

Key Differences Between 403(b) and 457(b)

403(b) — Tax-Sheltered Annuity. Contributions come from pre-tax salary. Withdrawals before age 59½ are subject to a 10% early withdrawal penalty plus income tax (with limited exceptions for separation from service at age 55 or older). Employer non-elective contributions — a common retirement incentive — go into the 403(b) and are not reportable to NYSTRS.

457(b) — Deferred Compensation Plan. Contributions also come from pre-tax salary. The critical advantage: there is no 10% early withdrawal penalty at any age once you separate from service. If you retire at 55, you can begin withdrawing from your 457(b) immediately without penalty. This makes the 457(b) particularly valuable for educators who retire before 59½ and need income before Social Security begins.

Both account types allow you to contribute up to the annual IRS limit ($23,500 in 2025, typically adjusted annually). If your district offers both, you can contribute the full limit to each — effectively doubling your supplemental savings.

Tax Treatment After Retirement

Your NYSTRS pension is fully exempt from New York State income tax. Your 403(b) and 457(b) withdrawals are not.

Withdrawals from both account types are taxable as ordinary income at the federal level. They are also taxable at the New York State level, subject to the $20,000 pension/annuity income exclusion available to New York residents age 59½ and older. That exclusion applies to the combined total of all qualifying pension and annuity income — so if your NYSTRS pension were taxable at the state level (it is not, since it is a NYS government pension), it would reduce the exclusion available for 403(b)/457(b) withdrawals.

In practice, the $20,000 exclusion applies to your 403(b) and 457(b) withdrawals directly, since your NYSTRS pension does not consume any of it.

Rollover Options at Retirement

When you separate from service, you have several choices for your supplemental accounts:

• Leave the money in the plan. Continue with the district's vendor and withdraw on your own schedule.
• Roll over to a traditional IRA. Consolidates accounts and may offer lower-cost investment options. No tax consequence if done as a direct trustee-to-trustee transfer.
• Roll over to a Roth IRA. Triggers a taxable event in the year of conversion, but all future growth and withdrawals are tax-free. Worth considering if you are in a low tax bracket in the year you retire.
• Take a lump-sum distribution. Fully taxable in the year received. Subject to the 10% penalty for 403(b) if you are under 59½ (but not for 457(b) after separation).

Service Credit Purchases and Rollovers

If you are purchasing prior service credit from NYSTRS, you can pay the cost using a direct trustee-to-trustee rollover from your 403(b) or traditional IRA. This avoids triggering income tax on the transfer. The payment must reach NYSTRS before your effective retirement date — NYSTRS cannot credit prior service purchased after that date.

The 457(b) cannot be used for service credit purchases through a direct rollover in the same way. Check with your plan administrator and NYSTRS for current transfer rules.
