Can You Contribute to a 457 After Retirement?

Once you retire, you generally cannot keep contributing to a 457(b) plan. Federal law limits participation to people actively performing services for the sponsoring employer, so your ability to defer new compensation ends when your employment does. The one meaningful exception is a final deferral of accrued leave through your last paycheck, and contributions can resume later if you go back on a qualifying employer’s payroll or take a contract with one.

Why Retirement Closes the Door

The statute governing 457(b) plans limits participation to individuals who perform services for the eligible employer.¹ Eligibility to defer depends on a current service relationship with a qualifying employer, meaning a state or local government agency, a school district, or a tax-exempt nonprofit that sponsors the plan.²

Retirement severs that relationship. The payroll mechanism that channels part of your salary into the plan stops functioning, and plan administrators verify eligibility through payroll records. Without active wages from the sponsoring employer, there is nothing to defer. Pension checks, Social Security, distributions from other retirement accounts, and investment income do not qualify as compensation for services and cannot be redirected into your 457(b).

The One Exception: Deferring Your Accrued Leave

The most practical way to squeeze a final contribution into the plan is to defer part or all of your accrued leave payout. Many career employees retire with hundreds of hours of unused vacation or sick time, and that final cash-out counts as compensation from the employer. Because it is paid through payroll before your separation is fully processed, it is eligible for deferral.

Timing is the trap. Federal regulations require a salary reduction agreement to be signed before the first day of the month in which the compensation is paid.³ If your leave payout lands in July, the signed agreement has to be on file no later than June 30. Miss the deadline and the money hits your bank account as taxable wages with no second chance to reroute it.

The agreement should specify a dollar amount or a percentage of the payout. If you have 200 hours of unused vacation valued at $50 per hour, that is a $10,000 payout you could direct into the plan. But the deferral still counts against the annual contribution limit. For 2026, the basic limit is $24,500.⁴ Anything you already deferred from earlier paychecks in the same calendar year reduces the room available. Amounts over the cap get paid out as regular wages.

One detail people miss: a 457(b) deferral cuts your federal and state income tax for the year, but it does not escape FICA. Social Security and Medicare taxes apply when the services are performed, so your accrued leave deferral still gets hit with payroll taxes on the way in.

Max Out Before You Go: Catch-Ups You Lose at Separation

If you are approaching retirement and have room in the plan, several catch-up provisions let you contribute well beyond the standard limit. All of them require active employment. Once you separate, the opportunity is gone.

Age 50 Catch-Up

Governmental 457(b) plans can offer a catch-up for participants who reach age 50 by the end of the tax year. For 2026, this adds $8,000 to the basic limit, for a total of $32,500.⁴ Tax-exempt 457(b) plans do not offer this catch-up.⁵

Super Catch-Up for Ages 60 Through 63

Starting in 2025, participants in governmental 457(b) plans who are 60, 61, 62, or 63 at year-end qualify for a higher catch-up in place of the age-50 amount. For 2026, the super catch-up is $11,250, allowing a maximum contribution of $35,750.⁴ For someone planning to retire at 64 or 65, these are the years to load up.

The Special Three-Year Catch-Up

Both governmental and tax-exempt 457(b) plans can offer a special catch-up during the three tax years immediately before you reach the plan’s normal retirement age. The limit is the lesser of twice the basic annual limit or the basic limit plus your unused deferral room from prior years.⁶ For 2026, doubling the basic limit means up to $49,000 in a single year if you have enough unused room banked.

Normal retirement age under the plan is typically the earlier of 65 or the age at which you are entitled to full benefits under the employer’s pension, and it cannot be later than 70½.⁶ The unused-room calculation gets complicated, especially for years before 2002 when different coordination rules applied. Ask the plan administrator to run the numbers.

You cannot use the special three-year catch-up and the age-50 (or 60-63) catch-up in the same year. If you qualify for both, take whichever produces the higher limit.⁵

If You Go Back to Work

The restriction lifts the moment you return to a qualifying employer’s payroll. Take a position with a state agency, school district, or other entity that sponsors a 457(b), and you can enroll and defer from your new salary. It does not matter whether you return to your old employer or start with a different one. Submit a new enrollment form and salary reduction agreement, and your total 457(b) deferrals for the calendar year still have to fit under the federal limit ($24,500 for 2026, plus any catch-up you qualify for).⁷

A useful quirk for people who come back: the 457(b) limit is independent of the 401(k) and 403(b) limit. If your new employer also offers a 403(b) or 401(k), you can max both plans in the same year, before catch-ups. Few other retirement vehicles allow that stacking.

Your return has to be real. If you “retire” on Friday and start the same job at the same desk on Monday under a different arrangement, the IRS looks at whether the duties and work environment genuinely changed, not just whether the paperwork was reshuffled.

Returning as a Contractor

The statute does not limit 457(b) participation to W-2 employees. It covers anyone who performs services for the eligible employer, and the regulations explicitly include independent contractors.⁸ Retire from a government agency, come back later as a consultant to the same or a different qualifying entity, and you may be able to participate in their plan.

The practical hurdles are real. The plan document has to allow contractor participation, and many do not. Your contract income counts as your includible compensation for contribution purposes, so what you can defer is capped at what you actually earn under the contract. And the separation between your retirement and the contract needs to be genuine. If the agency lined up the contract before you left, the IRS could argue there was never a real separation from service.

Rollovers Are Not Contributions

Rolling money from a 401(k), 403(b), or IRA into a governmental 457(b) is not a contribution. Rollovers are transfers between retirement accounts. They do not require active employment and they do not count against your annual deferral limit.⁹

Two caveats. Only governmental 457(b) plans accept rollovers from other plan types; tax-exempt 457(b) plans cannot receive them at all.⁵ And rolled-in money keeps its original character for penalty purposes. Amounts that originate inside a 457(b) generally escape the 10% early withdrawal penalty that applies to 401(k) and 403(b) distributions before age 59½, but money rolled in from a 401(k) or IRA does not lose that penalty exposure. Pull the rolled-in portion out before 59½ and the 10% applies to that piece.⁹
