You generally cannot keep contributing to a 457(b) after retirement, because new elective deferrals require pay from the sponsoring employer, and once your paychecks stop there is nothing left to defer.1Office of the Law Revision Counsel. 26 USC 457 – Deferred Compensation Plans of State and Local Governments and Tax-Exempt Organizations A few narrow moves can still add money to the plan: deferring a final leave payout, using catch-up provisions during your last working years, rolling in balances from other retirement accounts, or returning to work for an eligible employer.
Why New Contributions Stop When You Retire
A 457(b) is a deferred-compensation plan for employees of state and local governments and certain tax-exempt organizations.2Internal Revenue Service. IRC 457(b) Deferred Compensation Plans Your annual deferrals cannot exceed the lesser of the dollar limit or 100% of your “includible compensation,” which is essentially pay for services performed for the sponsoring employer.1Office of the Law Revision Counsel. 26 USC 457 – Deferred Compensation Plans of State and Local Governments and Tax-Exempt Organizations
Pension checks, Social Security benefits, investment income, and distributions from the 457(b) itself do not count as includible compensation. You cannot route outside money into the plan to keep building the balance. No qualifying pay, no deferral.
Deferring Your Final Leave Payout
Many government and nonprofit employers cash out unused vacation, sick, or personal leave when you separate. Those payouts qualify as includible compensation because you earned them during active service. If your plan document allows it, you can direct part or all of that final check into your 457(b) as one last deferral.
Check your remaining room first. The standard deferral limit for 2026 is $24,500.3Internal Revenue Service. 2026 Amounts Relating to Retirement Plans and IRAs, as Adjusted for Changes in Cost-of-Living Whatever you have already deferred earlier in the year reduces what the payout can absorb.
Timing is strict. You must sign a deferral agreement before the first day of the month in which the payout is made.4eCFR. 26 CFR 1.457-4(b) – Annual Deferrals Under Eligible Plans If you retire on June 15 and payroll cuts the leave check in July, the paperwork has to be done by May 31. Most HR departments need the form earlier than that to update payroll, so raise it well before your last day.
Catch-Up Contributions in Your Final Working Years
If you are still on the job and nearing retirement, catch-up provisions let you push more into the plan while you still have wages coming in. Each has its own rules, and you cannot stack all of them in the same year.
Age 50 and Over
Governmental 457(b) plans may allow participants who reach age 50 by year-end to add a catch-up contribution on top of the standard limit. For 2026, the catch-up is $8,000, for a combined maximum of $32,500.3Internal Revenue Service. 2026 Amounts Relating to Retirement Plans and IRAs, as Adjusted for Changes in Cost-of-Living It is available every year from age 50 onward if the plan permits it and you remain employed.5Internal Revenue Service. Retirement Topics – Catch-Up Contributions
Ages 60 Through 63
Under SECURE 2.0, participants who turn 60, 61, 62, or 63 during the tax year qualify for a higher catch-up in place of the age-50 amount. For 2026, that enhanced catch-up is $11,250, for a combined maximum of $35,750.3Internal Revenue Service. 2026 Amounts Relating to Retirement Plans and IRAs, as Adjusted for Changes in Cost-of-Living Your plan must specifically permit it, so confirm with the plan administrator if you fall in that window.6Federal Register. Catch-Up Contributions
Special Three-Year Catch-Up
Governmental 457(b) plans may also offer a special catch-up during the three years immediately before the plan’s stated normal retirement age. This is designed to recover unused contribution room from earlier years. The extra amount is the lesser of the current annual limit ($24,500 in 2026) or your accumulated unused limits, which can effectively double your deferral to as much as $49,000.7Internal Revenue Service. Retirement Topics – 457(b) Contribution Limits
One limit on stacking: in any year you use the special three-year catch-up, you cannot also use the age-50 or age 60–63 catch-up. Pick whichever gives you the higher number that year.7Internal Revenue Service. Retirement Topics – 457(b) Contribution Limits
Going Back to Work
The one clean way to restart deferrals after retiring is to return to work for an eligible employer, meaning a state or local government or qualifying tax-exempt organization. New employment produces new includible compensation, which reopens your ability to make elective deferrals.1Office of the Law Revision Counsel. 26 USC 457 – Deferred Compensation Plans of State and Local Governments and Tax-Exempt Organizations
Even if you rejoin the same employer, the plan may treat you as a new participant for enrollment purposes. You will need to satisfy any eligibility conditions the plan imposes, such as hours or job classification, and submit a fresh salary reduction agreement. The same annual limits then apply, up to $24,500 for 2026 plus any catch-up you qualify for.3Internal Revenue Service. 2026 Amounts Relating to Retirement Plans and IRAs, as Adjusted for Changes in Cost-of-Living
Contract work can count too. Governmental 457(b) plans allow independent contractors who perform services for the employer to participate, not only regular employees.8Internal Revenue Service. Comparison of Tax-Exempt 457(b) Plans and Governmental 457(b) Plans If you pick up a contract with a government agency after retiring, its plan may let you contribute, depending on the terms.
Rolling Money In From Other Retirement Accounts
You cannot make new deferrals without wages, but a governmental 457(b) can accept rollover contributions from a traditional IRA, a 401(k), a 403(b), or another governmental 457(b).9Internal Revenue Service. Rollover Chart A rollover is a transfer of money already inside the retirement system, not a new deferral, so the includible compensation rule does not block it.
Acceptance is up to the plan. Governmental 457(b) plans must let you roll money out, but they are not required to take rollovers in. Ask the plan administrator whether the plan accepts the specific account type you want to move. One catch to know before you decide: money rolled into a 457(b) from a non-457 source can be subject to the 10% early-withdrawal penalty if you take it out before age 59½, a penalty that does not normally apply to original 457(b) money.
What You Can Still Do With the Account
Once you separate from the sponsoring employer, the balance in your 457(b) becomes available for withdrawal at any age. Original 457(b) money is not subject to the 10% early-withdrawal penalty even if you are under 59½. You will owe ordinary income tax on what you take out, but the extra penalty that affects early withdrawals from other plan types does not apply.
You can take a lump sum, set up periodic payments, or combine approaches. Whatever you leave in the account keeps growing tax-deferred. The clock does eventually catch up: at age 73, once you have separated from service, you must begin required minimum distributions each year.10Internal Revenue Service. Retirement Plan and IRA Required Minimum Distributions FAQs If you are still working for the plan sponsor past 73, RMDs from that plan can generally wait until you actually retire. Missing an RMD triggers a steep excise tax on the amount you should have withdrawn, so track the deadline once you reach that age.
