2026 401(k) Contribution Limits
The IRS sets annual limits on how much you can contribute to your 401(k). For 2026, the employee contribution limit is $23,500. If you're 50 or older, you can make additional catch-up contributions of $7,500, bringing your total to $31,000.
These limits apply only to your own contributions. Employer match contributions don't count toward this limit. The total combined limit (employee + employer) is $70,000 for 2026, or $77,500 with catch-up contributions. This means employer match is truly "extra" — it doesn't eat into your contribution room.
Contributing the maximum is an excellent way to accelerate retirement savings, especially since 401(k) contributions reduce your taxable income dollar for dollar (for Traditional contributions). On a $100,000 salary, maxing your 401(k) at $23,500 drops your taxable income to $76,500.
How Employer Match Works
Employer match is the single best return on investment in personal finance — it's an instant 50-100% return before any market gains. A typical match formula is "50% of employee contributions up to 6% of salary." On a $70,000 salary contributing 6%, your employer adds $2,100/year in free money.
Not all match programs are equal. Some employers offer dollar-for-dollar matching (100%), others match 50 cents on the dollar, and the cap varies from 3% to 10% of salary. Always contribute at least enough to capture your full employer match — anything less is leaving part of your compensation on the table.
Be aware of vesting schedules. While your own contributions are always yours, employer match contributions may vest over 3-6 years. Cliff vesting gives you 0% until a specific date (often 3 years), then 100%. Graded vesting increases your ownership gradually (e.g., 20% per year).
Frequently Asked Questions
What is the 401(k) contribution limit for 2026?
The 2026 401(k) contribution limit is $23,500 for employee contributions. If you're 50 or older, you can contribute an additional $7,500 in catch-up contributions, bringing the total to $31,000. These limits apply to your own contributions only — employer match contributions don't count toward this limit.
How does a 401(k) employer match work?
An employer match means your company contributes money to your 401(k) based on how much you contribute. A common match is '50% of contributions up to 6% of salary.' On a $70,000 salary, if you contribute 6% ($4,200), your employer adds $2,100. Not contributing enough to get the full match is leaving free money on the table.
What is 401(k) vesting?
Vesting determines how much of your employer's match you get to keep if you leave the company. Your own contributions are always 100% vested. Employer matches may vest gradually (e.g., 20% per year over 5 years) or cliff vest (100% after 3 years). Check your plan's vesting schedule.
Should I choose Traditional or Roth 401(k)?
Traditional 401(k) contributions reduce your taxable income now, and you pay taxes on withdrawals in retirement. Roth 401(k) contributions are made with after-tax dollars, but withdrawals are tax-free. Choose Roth if you expect to be in a higher tax bracket in retirement; choose Traditional if you expect a lower bracket.
What happens if I withdraw from my 401(k) early?
Withdrawing before age 59½ typically incurs a 10% early withdrawal penalty plus regular income taxes. There are exceptions: the Rule of 55 allows penalty-free withdrawals if you leave your job at 55 or later, and hardship withdrawals may be available for certain financial emergencies.
How much should I contribute to my 401(k)?
At minimum, contribute enough to capture your full employer match. Beyond that, aim for 15% of your pre-tax income (including the match). If you started saving late, contribute more aggressively — the catch-up contribution is designed to help those 50+ close the gap.
