401(k) Contribution Limits 2026: Catch-Up, Employer Match, Roth 401(k)
What changed for 2026
The IRS raised 401(k) contribution limits for 2026 in line with inflation and the SECURE 2.0 schedule. The headline numbers:
- Employee elective deferral limit: $24,500 (up from $24,000 in 2025).
- Standard catch-up at age 50+: $7,500 (unchanged from 2025).
- “Super catch-up” at ages 60–63: $11,250 (a SECURE 2.0 feature, in addition to the standard catch-up).
- Total annual contribution limit (employee + employer + after-tax): $73,500 ($82,000 if 50+ with catch-up; $86,750 if 60–63 with super catch-up).
- Compensation limit (the maximum salary against which contributions can be calculated): $360,000.
Together these mean a 60-year-old earning enough can defer $35,750 of personal contributions ($24,500 + $11,250) in 2026 — the highest individual 401(k) deferral ceiling ever offered.
Employee deferrals vs total contributions
The $24,500 limit applies only to your own salary deferrals — the money taken from your paycheck. Employer contributions (match, profit sharing, non-elective) sit on top, subject to a separate combined limit of $73,500. So an employee deferring the full $24,500 can still receive up to $49,000 in employer contributions before hitting the IRS overall cap.
In practice, employer contributions rarely come anywhere near that ceiling. A typical large-employer match is 50% on the first 6% of pay or 100% on the first 4-5% — far below the $49,000 headroom. Profit-sharing employers and small-business retirement plans (like Solo 401(k)s for self-employed people) use more of the combined limit; high-income solo-employed taxpayers can effectively shelter $80,000+ in a Solo 401(k) once both the employee deferral and the employer contribution (as a percentage of net self-employment income) are added.
The catch-up structure
The SECURE 2.0 Act introduced a tiered catch-up that produces three different limits at different ages:
| Age in 2026 | Base deferral | Catch-up | Total employee limit |
|---|---|---|---|
| Under 50 | $24,500 | — | $24,500 |
| 50 – 59 | $24,500 | $7,500 | $32,000 |
| 60 – 63 | $24,500 | $11,250 (super) | $35,750 |
| 64+ | $24,500 | $7,500 | $32,000 |
The super-catch-up window is a four-year acceleration at the end of working life. After age 63 the limit drops back to the standard $7,500 catch-up. SECURE 2.0’s logic: late-career earners who haven’t saved enough get a final window to catch up before retirement.
There’s also a SECURE 2.0 rule effective 2026 requiring catch-up contributions to be made on a Roth basis for employees earning over $145,000 (indexed) in the prior year from the same employer. If your plan doesn’t offer a Roth 401(k) sub-account, you simply can’t make catch-up contributions in 2026 if you fall above that wage threshold. Many plan sponsors have added Roth options specifically to comply.
The employer match
The employer match is — by a wide margin — the single highest-return investment available to a typical employee. A 50% match on 6% of pay is, in effect, a 50% guaranteed return on those dollars before any market exposure. The first dollar contributed to capture the match beats every other dollar of saving you’ll do.
A few critical match mechanics:
- Match vesting: employer contributions vest on a schedule (often 3-year cliff or 6-year graded). If you leave before fully vested, you forfeit the unvested portion of the match (not your own contributions, which are always 100% vested). The IRS rules cap how long vesting can take — but your specific schedule is in your plan document.
- True-up provisions: some plans match per pay period; others true up at year-end. If you front-load your contributions (max early to harvest more market time), a per-pay-period match can leave you with less total match than spreading the contributions evenly. Always check whether your plan has a true-up; if it doesn’t, the contribution timing matters.
- Match formula stacking: an increasingly common formula is “100% of the first 3%, then 50% of the next 2%”. Capturing the full match in this case means deferring at least 5% of pay.
- Roth contributions match: under SECURE 2.0, employers can match Roth 401(k) contributions with Roth-basis matching (taxed to the employee in the year of the match, but tax-free in retirement). Most employers still match into the pre-tax bucket — check your plan.
Roth vs Traditional 401(k)
If your plan offers both, the choice mirrors the Roth vs Traditional IRA decision: pre-tax now and pay tax in retirement, or pay tax now and pull out tax-free.
A 401(k)-specific twist: there are no income limits on Roth 401(k) contributions. The income phase-outs that block high earners from contributing directly to a Roth IRA don’t exist for Roth 401(k). High-income earners who can’t direct-fund a Roth IRA can still build a Roth balance through the workplace 401(k).
A second twist: mandatory Roth catch-up for high earners under SECURE 2.0 means if you earn over $145,000 (indexed), your catch-up dollars have to go Roth. The base $24,500 can still be either pre-tax or Roth at your election.
Mega backdoor Roth — for the few plans that allow it
Some employer 401(k) plans permit after-tax (non-Roth) employee contributions on top of the $24,500 elective deferral, then allow in-plan conversion to Roth. This “mega backdoor Roth” can move tens of thousands of dollars per year into a Roth bucket — up to the combined $73,500 ceiling minus the elective deferral and any match.
The plan has to allow both after-tax contributions and in-plan Roth conversions; most don’t. If yours does, it’s one of the most powerful tax-shelter tools available — a SaaS employee with a high salary and access to the mega backdoor can move $30,000+ a year into Roth on top of the standard $24,500.
Loans, hardship withdrawals and rollovers
A few rules that influence the practical use of a 401(k):
- 401(k) loans: most plans allow loans up to 50% of vested balance, max $50,000, with repayment via payroll deduction over up to 5 years (longer for home purchase). Loans aren’t taxable as long as repaid; if you leave the employer with an outstanding balance, the balance is treated as a distribution and taxed unless rolled to another plan within a short window.
- Hardship withdrawals: now slightly easier under SECURE 2.0 — you can self-certify hardship for some categories, and the 10% early-withdrawal penalty has been waived for several specific situations (federally declared disasters, domestic abuse, terminal illness, certain emergency expenses).
- Rollovers when you leave a job: typical destinations are an IRA (more investment choice, no further 401(k) protections under ERISA), the new employer’s 401(k) (clean, simple, easier to manage one account), or leaving the money in the old plan (allowed if balance is above $7,000; small balances can be force-cashed-out). For most people the new-employer 401(k) is the cleanest option if available and the fees are competitive.
Worked example: 35-year-old at $120,000
A single employee, age 35, earning $120,000, contributes 10% to the 401(k) with a 50% match on the first 6%.
- Employee deferral: 10% × $120,000 = $12,000.
- Employer match: 50% × 6% × $120,000 = $3,600.
- Total contribution: $15,600.
- Tax saving (assume 22% marginal): $12,000 × 22% = $2,640. After-tax cost of the $15,600 contribution is $9,360.
Use the 401(k) calculator to project a balance at retirement with this contribution rate and employer match.
To max the elective deferral at $24,500, the same employee would need to defer 20.4% of pay. The match doesn’t increase further because it’s capped at the first 6%. Maxing the 401(k) without changing the match isn’t usually about chasing more match — it’s about using the tax-advantaged space.
Frequently asked questions
What’s the difference between the 401(k) limit and the IRA limit? Separate buckets, separate limits. $24,500 for 401(k) elective deferrals; $7,500 for IRA contributions. You can max both in the same year.
My company matches into the pre-tax bucket — does that count against the $24,500? No. The $24,500 is the employee elective deferral limit. Employer match counts against the combined $73,500 limit, not the $24,500 employee cap.
Do I lose unused 401(k) contribution room? Yes — unlike IRA limits in some other countries, 401(k) limits don’t carry forward. Use it or lose it each calendar year.
Can I make 401(k) contributions for the prior year? No. 401(k) contributions must be made via payroll deduction during the calendar year. Unlike IRA contributions, there’s no extension window past year-end. (Employer contributions, by contrast, can be made up to the tax filing deadline.)
What if I work for two employers in the same year? The $24,500 elective deferral limit is per person, not per plan. If you contribute to two 401(k)s in the same year (typical when changing employers), the combined deferral can’t exceed $24,500. If you over-contribute, you have to withdraw the excess by April 15 of the following year — and pay tax on it in both the year of contribution and the year of withdrawal.
