401k Contribution Limits: Annual Update Guide

The IRS adjusts retirement account contribution limits annually based on inflation. For 2026, 401k and similar workplace retirement plan limits have increased, giving you more room to save in tax-advantaged accounts.

Here is what you need to know about the 2026 limits and how to take advantage of them.

2026 401k Contribution Limits

The employee contribution limit for 401k, 403b, and most 457 plans is $24,500 for 2026, up from $23,500 in 2025.

If you are 50 or older, you can make additional catch-up contributions of $8,000, bringing your total employee contribution to $32,500.

SECURE 2.0 introduced a special catch-up provision for workers ages 60 through 63. If you fall in this age range in 2026, your catch-up limit increases to $11,250, allowing total contributions of $35,750.

The Roth Catch-Up Rule

Starting in 2026, if you earned more than $150,000 in FICA wages in the previous year, your catch-up contributions must be made to a Roth account (if your plan offers one), not traditional pre-tax. Check Box 3 on your W-2 to see if this applies to you.

This does not affect your regular contributions, only the catch-up portion. And it only applies if your employer offers a Roth 401k option.

Employer Contributions and the Total Limit

The limits above are for employee contributions only. Employers can also contribute to your account through matches or profit sharing.

The total limit for employee plus employer contributions is $72,000 for 2026 ($79,250 if you are 50+ using catch-up). Few employees hit this combined limit, but high earners at generous companies might approach it.

Strategies to Maximize Contributions

If you want to contribute the maximum, calculate your required per-paycheck amount. Divide $24,500 by your number of pay periods. For biweekly pay (26 periods), that is about $942 per paycheck.

Some people front-load contributions to get money invested earlier in the year. Be careful with this approach if your employer matches per-paycheck contributions. You might miss out on match if you max out before year-end.

Review your contribution percentage early in the year to ensure you are on track. Many plans allow you to set a specific dollar amount per paycheck rather than a percentage, which can simplify hitting exact targets.

Roth vs Traditional 401k

If your plan offers both traditional (pre-tax) and Roth (after-tax) options, you need to decide how to split contributions.

Traditional contributions reduce your taxable income now. You pay taxes when you withdraw in retirement. Roth contributions are made with after-tax dollars, but qualified withdrawals in retirement are tax-free.

If you expect higher taxes in retirement than now, Roth makes sense. If you expect lower taxes in retirement, traditional is often better. If you are unsure, splitting between both provides flexibility.

Do Not Leave Employer Match on the Table

If your employer offers matching contributions, contribute at least enough to get the full match. This is essentially free money. A common match is 50% of contributions up to 6% of salary. That means contributing 6% gets you 3% from your employer.

Even if you cannot afford to max out, prioritize getting the full match. Then consider IRA contributions or additional 401k contributions depending on your situation.

Retirement plan rules are complex. Consult your plan administrator or a tax professional for guidance specific to your situation.
