2026 Contribution Limits at a Glance
| Account Type | Under 50 | Age 50–59 & 64+ | Age 60–63 (SECURE 2.0) |
|---|---|---|---|
| 401(k), 403(b), 457(b) | $23,500 | $31,000 | $34,750 |
| SIMPLE IRA | $16,500 | $20,000 | $22,500 |
| IRA (Roth or Traditional) | $7,000 | $8,000 | $8,000 |
The SECURE 2.0 Act introduced a special higher catch-up limit for ages 60–63, allowing an extra $11,250 on top of the base $23,500 — for a total of $34,750. This is one of the most significant retirement savings opportunities for people in their early 60s.

Catch-Up Contributions (Age 50+)
Once you turn 50, the IRS allows you to contribute more than the standard limit — called a "catch-up contribution." In 2026:
- Age 50–59: Standard $23,500 + $7,500 catch-up = $31,000 total
- Age 60–63: Standard $23,500 + $11,250 catch-up = $34,750 total (SECURE 2.0 enhanced limit)
- Age 64+: Returns to standard catch-up: $23,500 + $7,500 = $31,000 total
The age 60–63 window is a powerful opportunity. If you're in that range and can afford to maximize contributions, the tax-deferred compounding on that extra $3,750/year (vs. the standard catch-up) adds up meaningfully over even a few years.
Employer Match and Total Limit
Your personal contribution limit is separate from your employer's match. The combined limit (your contributions + employer contributions) in 2026 is $70,000 (or 100% of your compensation, whichever is less). For those 50+, the combined limit is $77,500.
Common employer match structures:
- 100% match up to 3% of salary: You contribute 3%, employer adds 3% — total 6%
- 50% match up to 6% of salary: You contribute 6%, employer adds 3% — total 9%
- Dollar-for-dollar up to $5,000: Fixed dollar amount regardless of salary
Always contribute at least enough to capture the full employer match. It's an immediate 50–100% return on your money — no investment can reliably beat that.
Strategies to Maximize Your 401(k)
- Increase by 1% per raise. Every time you get a raise, increase your 401(k) contribution by 1%. You'll never miss money you never received in your paycheck.
- Front-load if you can. Contributing more early in the year gives your money more time to compound — but make sure you don't hit the limit before year-end if your employer matches per-paycheck (you'd miss some match).
- Review your investment options. Many 401(k) plans have high-fee funds. Look for low-cost index funds (expense ratio under 0.10%). If your plan only has expensive options, contribute enough for the match, then max your IRA in better funds.
- Rebalance annually. Check your allocation once a year and rebalance back to your target. Most plans allow automatic rebalancing.
- Don't cash out when changing jobs. Rolling your 401(k) to an IRA or your new employer's plan preserves the tax-deferred growth. Cashing out triggers income tax plus a 10% penalty.
Roth 401(k) vs. Traditional 401(k)
Many employers now offer a Roth 401(k) option alongside the traditional pre-tax 401(k). The same contribution limits apply to both — but the tax treatment differs:
| Feature | Traditional 401(k) | Roth 401(k) |
|---|---|---|
| Contributions | Pre-tax (reduces taxable income now) | After-tax (no immediate deduction) |
| Withdrawals in retirement | Taxed as ordinary income | Tax-free |
| Required minimum distributions | Yes, starting at 73 | No (as of SECURE 2.0) |
| Income limits | None | None |
| Best for | High earners now; lower bracket expected in retirement | Lower earners now; higher bracket expected in retirement |
For a deeper comparison, see our Roth vs. Traditional IRA guide — the same core logic applies to 401(k) choices.
FAQ
What happens if I contribute too much to my 401(k)?
Excess contributions must be withdrawn by April 15 of the following year. If not corrected, the excess is taxed twice — once when contributed and again when withdrawn. Contact your plan administrator immediately if you over-contribute.
Can I contribute to both a 401(k) and an IRA?
Yes — they have separate contribution limits. You can max both a 401(k) ($23,500) and an IRA ($7,000) in the same year for a combined $30,500 in tax-advantaged contributions. See our Roth IRA limits guide.
Does my employer match count toward the $23,500 limit?
No — the $23,500 limit applies only to your personal contributions. Employer contributions are separate and count toward the combined $70,000 limit.
What if my employer doesn't offer a 401(k)?
Open an IRA (Roth or Traditional) as your primary retirement account. If you're self-employed, a Solo 401(k) or SEP-IRA allows much higher contribution limits. See our self-employed retirement accounts guide.
