What Is Self-Employment Tax?

Self-employment (SE) tax is the combined Social Security and Medicare tax that self-employed individuals must pay. It equals 15.3% of your net earnings from self-employment — 12.4% for Social Security and 2.9% for Medicare.

How It Differs From Employee Taxes

Employees pay 7.65% (matched by their employer). As a self-employed individual, you effectively pay the full 15.3% — but you can deduct half of the SE tax as an adjustment to income.

Income Cap for Social Security Tax

Social Security tax only applies to the first $176,100 of net earnings in 2026 (subject to inflation adjustment). Medicare tax has no cap.

Net Earnings from Self-Employment

To calculate SE tax, start with your Schedule C net profit. Multiply by 92.35% (only that portion is subject to SE tax). Then apply 15.3%.

Strategies to Reduce SE Tax

  • Deduct half of SE tax on Form 1040 (above-the-line deduction).
  • Retirement contributions — SEP-IRA and Solo 401(k) reduce net earnings subject to SE tax.
  • Business deductions — the more legitimate expenses you deduct, the lower your SE tax base.
  • elect S Corp status — split earnings into salary (subject to payroll tax) and distributions (not subject to SE tax).
