If you participate in a governmental 457(b) plan, 457 catch-up contributions let you exceed the standard $24,500 deferral limit for 2026 in one of two ways: an $8,000 age 50+ catch-up available in most retirement plans, or a special pre-retirement catch-up unique to 457(b) plans that permits up to twice the standard limit during the three years before your plan’s normal retirement age. You can only use one in a given tax year. Starting in 2025, SECURE 2.0 added a third option for participants aged 60 through 63.1Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500
Age 50+ Catch-Up
This is the same catch-up found in 401(k)s and 403(b)s. Any participant who turns 50 by December 31 of the tax year can contribute an additional amount on top of the standard deferral limit. For 2026, that amount is $8,000, bringing the total possible contribution to $32,500.1Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500 No extra paperwork is required. If you’re 50 or older and haven’t elected the special pre-retirement catch-up, the higher limit applies automatically once your contributions exceed the standard cap.
Special Pre-Retirement Catch-Up
The special pre-retirement catch-up exists only in 457(b) plans, and it can be much larger than the age 50+ amount. It lets participants make up for years they contributed less than the maximum, and it’s available during the three calendar years immediately before the year the participant reaches the plan’s normal retirement age.2Internal Revenue Service. Issue Snapshot – Section 457(b) Plan of Governmental and Tax-Exempt Employers – Catch-Up Contributions
The maximum annual contribution under this provision is the lesser of twice the standard deferral limit or the participant’s total accumulated unused deferrals from prior years. In 2026, that puts the absolute ceiling at $49,000, and only participants with at least $24,500 in unused deferral capacity from earlier years can hit it.3Office of the Law Revision Counsel. 26 U.S. Code 457 – Deferred Compensation Plans of State and Local Governments and Tax-Exempt Organizations
Unlike the age 50+ catch-up, this one isn’t automatic. You have to elect it, and doing so triggers the plan administrator’s review of your entire contribution history.
How the Unused Deferral Pool Is Calculated
The administrator reconstructs your contribution history back to your first year of eligibility. For each prior year, they identify the maximum allowable deferral limit, compare it to what you actually contributed, and record the gap. The sum of those gaps is your cumulative underutilized amount, and that pool is what’s available for catch-up contributions during the three-year window.2Internal Revenue Service.

Historical standard 457(b) deferral limits:4Internal Revenue Service. Cost-of-Living Adjustments for Retirement Items
- 2015–2017: $18,000
- 2018: $18,500
- 2019: $19,000
- 2020–2021: $19,500
- 2022: $20,500
- 2023: $22,500
- 2024: $23,000
- 2025: $23,500
- 2026: $24,500
If you contributed $10,000 in a year when the limit was $19,500, your unused amount for that year is $9,500. Do that math for every eligible year, add it up, and you have your catch-up pool.
The Double Limit in Practice
Say a participant entering year one of the three-year window in 2026 has $60,000 in accumulated unused deferrals. The standard 2026 limit is $24,500 and the double limit is $49,000. She can contribute $49,000 that year: $24,500 in standard deferrals plus $24,500 in catch-up. The remaining $35,500 carries forward to the next two years of the window.
A different participant with only $15,000 in total unused deferrals can contribute $39,500 in year one: $24,500 standard plus the full $15,000 catch-up. His catch-up capacity is exhausted, and the remaining two years revert to the standard limit or the age 50+ catch-up if he qualifies.
Defining Normal Retirement Age
The three-year window ends before you reach normal retirement age as defined by your plan. If the plan sets that age at 65, you can use the special catch-up at ages 62, 63, and 64. Plans have some flexibility here but the IRS caps normal retirement age at 70½. Some plans let individual participants pick a retirement age within the allowed range. A plan may also define normal retirement age as the earlier of 65 or the age at which the participant could receive unreduced benefits from the employer’s pension plan.2Internal Revenue Service. Issue Snapshot – Section 457(b) Plan of Governmental and Tax-Exempt Employers – Catch-Up Contributions The plan document controls, so verify with your benefits office before planning around specific ages.
The Enhanced Catch-Up for Ages 60 Through 63
Beginning in 2025, SECURE 2.0 created a higher catch-up contribution limit for participants who turn 60, 61, 62, or 63 by the end of the calendar year. It applies to governmental 457(b) plans that elect to adopt the provision.5Internal Revenue Service. COLA Increases for Dollar Limitations on Benefits and Contributions For 2026, the enhanced catch-up amount is $11,250, replacing the standard $8,000 age 50+ catch-up for participants in that age range. Combined with the $24,500 standard limit, a 60- to 63-year-old could contribute up to $35,750.
The statutory formula sets the enhanced amount at the greater of $10,000 or 150% of the regular age 50+ catch-up limit for that year.6Office of the Law Revision Counsel. 26 U.S. Code 414 – Definitions and Special Rules Once you turn 64, the catch-up reverts to the standard age 50+ amount.
Adoption is optional for plan sponsors, so not every governmental 457(b) will offer it right away. Check with your plan administrator.
You Can Only Pick One
The age 50+ catch-up (including the enhanced 60–63 version) and the special pre-retirement catch-up are mutually exclusive within a tax year. If you qualify for both, you pick whichever produces the larger contribution.7Internal Revenue Service. Retirement Topics – 457(b) Contribution Limits
The special pre-retirement catch-up usually wins when you have meaningful unused deferral capacity. It allows up to $49,000 in total contributions in 2026 compared to $35,750 under the enhanced age-based catch-up. But if your unused deferrals from prior years are limited, the enhanced catch-up can actually produce a higher contribution. Run the numbers for each year of the window rather than assuming the special catch-up always wins.
Stacking a 457(b) With a 403(b) or 401(k)
Governmental 457(b) contribution limits are separate from 401(k) and 403(b) limits. If your employer offers both a 457(b) and a 403(b), you can max out both in the same year.8Internal Revenue Service. How Much Salary Can You Defer if You’re Eligible for More Than One Retirement Plan? In 2026, a participant under 50 contributing the maximum to both a 403(b) and a governmental 457(b) could defer $49,000 total, $24,500 to each plan.
The separation extends to catch-up contributions. A participant 50 or older can use the age 50+ catch-up in both plans independently, contributing $32,500 to each for a combined $65,000. The special pre-retirement catch-up in the 457(b) doesn’t affect 401(k) or 403(b) limits at all, so the theoretical combined maximum for someone in the three-year window is higher still. It’s common for teachers, firefighters, and other public employees to have access to both plan types.
Non-Governmental 457(b) Plans
Tax-exempt employers like hospitals, charities, and trade associations can sponsor 457(b) plans, but these non-governmental versions handle catch-ups differently. They do not allow age 50+ catch-up contributions at all, and the enhanced 60–63 catch-up doesn’t apply either.9Internal Revenue Service. Non-Governmental 457(b) Deferred Compensation Plans The special pre-retirement catch-up is the only way to contribute above the standard limit.
Roth Catch-Up Requirement for High Earners
SECURE 2.0 requires catch-up contributions to be made on a Roth (after-tax) basis for participants who earned more than $150,000 in FICA wages during the prior year. Governmental plans received a delayed compliance deadline: the requirement applies for taxable years beginning after the later of December 31, 2026, or the close of the first regular legislative session that begins after December 31, 2025. For most governmental plans that means 2027 or 2028, depending on the state’s legislative calendar.
When it takes effect, the rule applies to all catch-up contributions, whether age 50+, the enhanced 60–63 amount, or the special pre-retirement catch-up. Participants under the $150,000 threshold will still be able to make catch-ups on either a pre-tax or Roth basis if the plan offers both. Plans without a Roth option will need to add one before the compliance date.
