If your employer offers a 401(k) or Roth 401(k) plan, contributing to it is a smart way to build a substantial nest egg. If you’re not already socking away the maximum allowed, consider increasing your contribution. With a 401(k), an employee elects to have a certain amount of pay deferred and contributed by an employer on his or her behalf to the plan. The contribution limit for 2020 is $19,500. Employees age 50 or older by year end are also permitted to make additional “catch-up” contributions of $6,500, for a total limit of $26,000 for 2020. The IRS recently announced that the 401(k) contribution limits for 2021 will remain the same as they are for 2020.
