The IRS issued new dollar limitations that are applicable to qualified retirement plans for plan years beginning in 2021 (except for the 401(k) deferral limit and Catch-Up Contribution limit, which apply on a calendar year basis). Some of the most commonly noted limitations are as follows: The limit on contributions by employees who participate in 401(k)s, 403(b)s, most 457 plans and the federal government’s Thrift Savings Plan remains unchanged at $19,500. The catch-up contribution limit for employees age 50 and older who participate in these plans remains unchanged at $6,500. The limitation for defined contribution (DC) plans under Section 415(c)(1)(A) (annual additions) has been increased for 2021 to $58,000 from $57,000. The limitation used in the definition of “highly compensated employee” under Section 414(q)(1)(B) remains unchanged at $130,000. The limitation on the annual benefit under a defined benefit plan under Section 415(b)(1)(A) remains unchanged at $230,000. Details on these and other retirement-related cost-of-living adjustments for 2021 can be found here, and are in IRS Notice 2020-79.
