You can contribute from 1% to 75% of your eligible base pay as pre-tax or Roth contributions, or a combination, up to the annual IRS dollar limits.
A Roth contribution to your Plan allows you to make after-tax contributions and take any associated earnings completely tax-free at retirement, as long as the distribution is a qualified one. A qualified distribution, in this case, is one that is taken at least five tax years after your first Roth 401(k) contribution and after you have attained age 59½, or become disabled or die.
The maximum contribution you can make to your 401(k) Plan in 2022 is $20,500.
If you have reached age 50 or will reach 50 during the calendar year January 1– December 31 and are making the maximum plan or IRS pre-tax contribution, you may make an additional $6,500 “catch-up” contribution in 2022.
