You can reduce taxes and save for retirement by contributing to a tax-advantaged retirement plan. If your employer offers a 401(k) or Roth 401(k) plan, contributing to it is a taxwise way to build a nest egg.
If you’re not already contributing the maximum allowed, consider increasing your contribution rate between now and year end. Because of tax-deferred compounding (tax-free in the case of Roth accounts), boosting contributions sooner rather than later can have a significant impact on the size of your nest egg at retirement.
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 2019 is $19,000. Employees age 50 or older by year end are also permitted to make additional “catch-up” contributions of $6,000, for a total limit of $25,000 in 2019.
The IRS just announced that the 401(k) contribution limit for 2020 will increase to $19,500 (plus the $6,000 catch-up contribution).
