How this calculator works
Self-employment tax is 15.3% (12.4% Social Security plus 2.9% Medicare) on 92.35% of your net profit. Social Security stops at the 2026 wage base of $184,500, counting any W-2 wages first. No tax is due if 92.35% of profit is under $400. Half of the tax is deductible on your return.
