Pre-Tax 401k vs After-Tax Roth Contributions
Next, you will select how much to contribute to your 401k. Roth and Traditional employee deferrals share the same annual IRS contribution limit. If you choose to split your contributions to pre-tax and after tax Roth, your total annual contributions cannot exceed the annual IRS limits.
For 2026, the limit is $24,500, subject to future cost-of-living adjustments. Members age 50 or older are eligible for catch-up contributions of an additional $8,000 per year, subject to future adjustments. Catch-up contributions are required to be made as post-tax Roth contributions.
Your election will remain in effect until changed in writing and processed by payroll.
