Catch-up + super catch-up

If you're 50 or older, you can contribute an extra $7,500 — bringing your max to $31,000. If you're 60, 61, 62, or 63, the SECURE 2.0 Act raised the catch-up to $11,250, bringing your max to $34,750. This higher cap ends at age 64, reverting you to $7,500.

High-earner Roth-only rule: from 2026, if your prior-year wages from the employer exceed $145,000 (indexed), ALL catch-up contributions must be Roth (post-tax). The regular $23,500 deferral can still be traditional. The rule was originally slated for 2024 but delayed twice; it takes effect in 2026.

Roth 401(k) vs Traditional 401(k)

Two factors dictate the choice:

  • Current vs retirement tax bracket. If you're currently at 32% and expect to retire at 22%, Traditional wins (deduct at 32%, pay at 22%). If you're at 22% now and expect higher brackets at retirement, Roth wins.
  • RMD avoidance. Roth 401(k)s have no Required Minimum Distributions during the account holder's lifetime (post-SECURE 2.0). Traditional 401(k)s force RMDs starting at age 73, which can push you into higher brackets.

Most career-growth workers hedge with a 50/50 split (Traditional + Roth). You get some deduction now and some tax-free retirement income.

Employer match — the free money

The most common employer match is 50% up to 6% of salary— i.e. your employer contributes 3% of your salary if you contribute 6%. At $100k income, that's $3,000/year of free money. A 100% match up to 3-4% is also common at tech companies.

Rule: contribute at least enough to capture the full employer match, even before paying off any non-credit-card debt. Missing the match is a guaranteed 50-100% loss on the matched portion.

Contribution strategy by career stage

  • 20s-early 30s: contribute to employer match, choose Roth (your bracket will likely rise). Focus surplus on ETFs outside 401(k) for liquidity.
  • Mid 30s-50s peak earning: max the $23,500 elective deferral, likely in Traditional (your bracket is at its peak). After employer match, consider maxing an HSA if eligible.
  • 50-59: max elective + $7,500 catch-up = $31,000. Start Roth conversions of old Traditional balances in low-income years.
  • 60-63: max elective + $11,250 super catch-up = $34,750. Biggest single opportunity in the system.
  • 64+: reverts to $31,000 max. Plan Social Security claiming + RMD avoidance.

Frequently asked questions

What is the 401(k) contribution limit for 2026?

Employee elective deferral: $23,500 (up from $23,000 in 2024). Age-50 catch-up: additional $7,500. SECURE 2.0 super catch-up (ages 60-63): additional $11,250. Combined employee + employer total cap: $70,000 (or 100% of compensation, whichever is lower). Numbers reflect the IRS Rev. Proc. inflation adjustment.

What is the SECURE 2.0 super catch-up?

Beginning 2025, workers aged 60, 61, 62, or 63 at the end of the plan year can contribute a "super catch-up" of up to $11,250 (150% of the regular $7,500 catch-up). At age 64, you revert to the standard catch-up. This rule was introduced in the SECURE 2.0 Act of 2022 to boost retirement savings in the critical pre-retirement window.

Should I contribute to Roth 401(k) or Traditional 401(k)?

Traditional = deduction now, tax on withdrawal. Roth = no deduction, tax-free withdrawal. Pick Traditional if you expect to be in a LOWER tax bracket in retirement (common for high earners today). Pick Roth if you expect to be in a HIGHER or the same bracket (common for early-career workers or those anticipating tax hikes). Most employers now offer both — splitting 50/50 is a reasonable hedge.

What happens if I exceed the limit?

If your contributions across all 401(k) plans in 2026 exceed $23,500, the excess is taxed in the year contributed AND again when withdrawn — double taxation. You have until April 15, 2027 to request a corrective distribution from the plan to avoid the double hit. This commonly happens when changing jobs mid-year — track year-to-date contributions carefully.

Is the new SECURE 2.0 Roth catch-up rule in effect for 2026?

Yes. For employees earning more than $145,000 from the employer in the prior year (adjusted for inflation), ALL catch-up contributions must be made to the Roth account only. This removes the traditional (pre-tax) option for high earners on catch-up dollars. The $23,500 regular deferral can still be traditional.
