2026 401(k) Contribution Limits

The official 2026 limits for 401(k), 403(b), TSP and 457(b) plans: the employee deferral, both catch-ups, the total additions cap and the Roth catch-up wage threshold.

The 2026 401(k) contribution limit is $24,500 in employee deferrals. At 50 or older you can add an $8,000 catch-up ($32,500 in total), and in the years you turn 60 to 63 the catch-up is $11,250 instead ($35,750 in total). Employee and employer contributions together are capped at $72,000. The same deferral limit applies to 403(b) plans, the TSP and governmental 457(b) plans.

Total annual additions limit (§415(c))Employee + employer + after-tax, catch-ups excluded $72,000
Compensation limit (§401(a)(17))Pay above this is ignored for plan contributions $360,000
Roth catch-up wage thresholdCatch-ups made in 2026 must be Roth if your 2025 FICA wages from the employer exceeded this $150,000

Unlike an IRA, a 401(k) deferral has to come out of pay dated in 2026; there is no filing-season window. Catch-ups also carry a Roth rule for 2026: if your 2025 FICA wages from the employer were over $150,000, your catch-up contributions must go in as Roth (IRS Notice 2025-67). The $11,250 higher catch-up is the SECURE 2.0 rule for the four years from age 60 through 63, and at 64 you drop back to the $8,000 amount.

Your 2026 401(k) limit

Employee deferrals only. Your plan must offer catch-ups for you to use them.

Paid tool Deciding between pre-tax contributions now and Roth conversions later is a multi-year bracket problem: every dollar deferred today has to come out later, in a year whose bracket and Medicare surcharge you are also choosing. The Roth Conversion Planner works that schedule: how much to convert in each year from now to your plan end age, the federal and state tax it costs, the IRMAA tier that year’s MAGI sets two years later, and the ACA subsidy it affects — set beside the same years with no conversions at all, and downloadable as a PDF you keep. A planning tool, not advice: the numbers move when your assumptions do. Build my conversion schedule — Personal PRO ($49) → See what is included, and price this year free, first →

Maxing the deferral is one lever — whether it beats a Roth conversion depends on your whole retirement tax path. QuantCalc runs your whole retirement — withdrawals, taxes, Medicare surcharges — year by year, on the 2026 figures above.
