To help your clients realize their biggest possible tax savings (as well as to increase their retirement savings), now is a great time to remind them that they should maximize their deferrals to their 401(k) plans. December 31, 2021 is the last day to do so for 2021, so there’s no time to delay! Deferral limits for 2021 are $19,500 with an additional $6,500 for those aged 50 or older.
