You can contribute from 1% to 75% of your eligible weekly base earnings, up to a maximum amount set yearly by the IRS. You may select pretax, Roth 401(k) or after-tax deferrals, or a combination of each. Your pretax contributions are deducted from your weekly base pay and are not subject to federal or state income tax.
If you select a Roth deferral, that portion of your contribution is taxed immediately. Roth contributions grow tax free for future distribution. An annually adjusted Internal Revenue Service (IRS) dollar limit also applies, and the dollar limit is $23,500 for 2025 (maximum for combined pretax and Roth 401(k) employee deferrals).
If you are 50 years old or older, you can make additional catch-up contributions of up to $7,500, for an annual contribution total of $31,000 for 2025.
Reminder to those eligible for the company match:
- To take full advantage of company matching contributions, elect a contribution percentage that allows you to contribute throughout the year.
- Reaching the IRS limit too early in the year will forfeit company matching contributions after the IRS limit is reached.
- There is no true-up with matching contributions.
- There is no match for after-tax deferrals.
