Schedule SE has been revised to allow for deferral of self-employment taxes. Self-employeds can defer a portion of their SECA tax on earnings from self-employment from March 27 to Dec. 31, 2020, with half of the deferred amount due Dec. 31, 2021, and the rest on Dec. 31, 2022. Figure the maximum deferral on Part III of Schedule SE. Include the total SECA tax on line 4, Schedule 2 of the 1040. The deferred amount goes on line 12e of Schedule 3. Opting for deferral doesn’t prevent self employeds from taking an above-the-line deduction for 50% of their total SECA tax for the year.
