Self-Employment Tax Calculator — 2026

See your self-employment tax, the deductible half, and how much to set aside each quarter so you don’t get an underpayment penalty.

TL;DR

Self-employed people pay 15.3% (Social Security + Medicare) on 92.35% of net profit, plus income tax. Half of the SE tax is deductible. This calculator shows how much to set aside for quarterly 1040-ES payments.
📅 Updated: 2026

If you also have a W-2 job: those wages already pay Social Security and use up the annual cap. Leave 0 if you have no employment income.

This is a planning estimate, not tax advice. The exact figure depends on deductions, credits and other income.
