The amount of annual pre-tax deferrals and Roth contributions you can make to a 401(k) plan is limited by the tax code. If you exceeded that limit in 2021, time is of the essence to correct the error. If you don’t act quickly, the tax consequences can be serious.
For 2021, you were limited to $19,500 in pre-tax deferrals and Roth contributions (plus an additional $6,000 if you were at least age 50 at the end of the year).
