A 457(b) is the retirement plan for employees of state and local governments and certain tax-exempt organizations. It sits alongside 401(k) (private sector), 403(b) (education and nonprofit), and 401(a) (government-defined contribution), and for many public employees a 457(b) is available in parallel with a 401(a) or 403(b). What makes the 457(b) distinctive is a withdrawal rule that doesn't exist in any of the other plans: distributions after separation from service are not subject to the standard 10% early-withdrawal penalty, regardless of the employee's age.
Who Qualifies for a 457(b) Plan 457(b) plans come in two flavors based on employer type. Governmental 457(b) plans are offered by state and local government agencies, public school districts, and public university systems. Tax-exempt 457(b) plans are offered by certain 501(c) organizations and have tighter eligibility rules (they're generally limited to a "top hat" group of management or highly compensated employees).
The governmental version is the more common one and the one most employees encounter. It's available broadly to eligible public employees and behaves more like a 401(k) in day-to-day operation than the tax-exempt variant does.
2026 Contribution Limits and Catch-Up Options The 2026 employee contribution limit is $24,500, matching 401(k) and 403(b) limits. Workers age 50 and older can add an $8,000 standard catch-up contribution, bringing the total to $32,500. Governmental 457(b) plans also allow the SECURE 2.0 super catch-up for workers age 60 through 63, at $11,250 instead of $8,000. See the IRS 2026 retirement plan limits for the full table.
What's the Special 457(b) Three-Year Catch-Up? In addition to the standard age-based catch-up, 457(b) plans include a unique three-year catch-up provision for employees within three years of the plan's normal retirement age. It allows participants to contribute up to twice the regular annual limit ($49,000 in 2026) if they have unused contribution room from prior years. An employee cannot use both the age-50 catch-up and the three-year catch-up in the same year; they have to pick the larger of the two.
How 457(b) Differs From 401(k) and 403(b) On the contribution side, 457(b) limits are now aligned with 401(k) and 403(b). The meaningful differences sit on the withdrawal side. A 401(k) participant who separates from service before age 59.5 and takes a distribution generally faces a 10% federal penalty on the withdrawal. A 457(b) participant in the same situation does not. The 457(b) was designed with the expectation that public employees might need access to their savings earlier than private-sector workers, which is why the early-withdrawal penalty doesn't apply.
A second difference: employees can often contribute to a 457(b) and a 403(b) or 401(a) simultaneously without the contribution limits offsetting each other. This creates significant retirement savings capacity for long-tenure public employees who contribute to both.
Administering a 457(b) Plan in 2026 For benefits and payroll teams at qualifying organizations, the 2026 administrative work is narrow but real. Update systems with the new $24,500 contribution limit and confirm the super catch-up is available for eligible employees. Verify that the three-year catch-up logic is correctly excluding participants who are using the standard age-50 catch-up. Confirm Roth contribution routing for high earners covered by SECURE 2.0's Roth catch-up requirement. Review plan documents if the plan has not been amended for recent SECURE 2.0 optional provisions.
The most common administrative issue in 457(b) plans is coordinating with parallel plans (401(a), 403(b)) so employees and plan administrators don't miss contribution capacity or inadvertently trigger aggregate limit issues.
