Why did the employee limit stay flat? The IRS only adjusts the 401(k) employee deferral limit in increments of $500. The 2025–2026 inflation level was not large enough to trigger a $500 increase, so the limit remains $23,500. The combined limit, which is calculated differently, increased slightly due to inflation adjustment of the overall annual additions limit.

Tax Impact

How 401(k) Contributions Reduce Your 2026 Tax Bill

Traditional 401(k) contributions are made pre-tax and directly reduce your taxable income in the year of contribution. This reduces both income tax and potentially the phase-out thresholds for other benefits.

Example: Single Filer, $90,000 Salary, $23,500 Traditional 401(k)

Gross salary$90,000
Traditional 401(k) contribution- $23,500
Gross income for tax purposes$66,500
Standard deduction (2026 projected)- ~$15,750
Estimated taxable income~$50,750
Estimated federal tax savings from 401(k)~$5,170

Always capture the full employer match first. If your employer matches contributions, contribute at least enough to get the full match before deciding between traditional and Roth. An employer match is free money and does not count toward your $23,500 personal limit.

Traditional vs. Roth 401(k) in 2026

The $23,500 limit applies to both traditional and Roth 401(k) contributions combined. You can split between the two in any proportion.

Frequently Asked Questions

The 2026 401(k) employee elective deferral limit is $23,500, unchanged from 2025. Workers aged 50 and older can add a $7,500 catch-up contribution for a total of $31,000. Workers aged 60–63 can use the SECURE 2.0 super catch-up of $11,250 for a total of $34,750. The combined limit including employer contributions is projected at approximately $71,000.
Yes. Contributing to a 401(k) does not prevent you from contributing to an IRA. The 2026 IRA contribution limit is $7,000 ($8,000 for those 50 and older). Note that the deductibility of traditional IRA contributions phases out if you or your spouse is covered by a workplace plan and your income exceeds certain thresholds.
Under the SECURE 2.0 Act, workers aged exactly 60, 61, 62, or 63 can make an enhanced catch-up contribution of $11,250 in 2026 — instead of the standard $7,500 for those 50–59 or 64+. This applies to 401(k), 403(b), and governmental 457(b) plans. The total annual limit for this group is $34,750 ($23,500 + $11,250).
No. The $23,500 employee limit applies only to your contributions through payroll deferral. Employer matching contributions, profit-sharing contributions, and other employer additions are separate and count toward the total combined limit (~$71,000 projected for 2026). The employer match does not reduce your personal $23,500 limit.
Employee 401(k) contributions must be made through payroll deductions during the calendar year. You cannot make a lump-sum 401(k) contribution after December 31 for the prior year (unlike IRAs). Self-employed individuals with a Solo 401(k) have until the business tax return due date (including extensions) to make employer contributions.
