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.
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)
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.
| Feature | Traditional 401(k) | Roth 401(k) |
|---|---|---|
| Tax on contributions | Pre-tax (reduces current income) | After-tax (no current deduction) |
| Tax on qualified withdrawals | Fully taxable as ordinary income | Tax-free |
| RMDs at age 73 | Required | Not required (post-SECURE 2.0) |
| Best if | In higher bracket now than retirement | In lower bracket now than retirement |
