How Self-Employment Tax Works

If you work for yourself, you are responsible for paying both the employer and employee portions of Social Security and Medicare taxes. This is collectively known as "Self-Employment Tax."

The Self-Employment Tax Rate

The total self-employment tax rate is 15.3%, consisting of:

  • 12.4% for Social Security (on the first $168,600 of net earnings for 2025).
  • 2.9% for Medicare (on all net earnings).

Deductions

The good news is that you can deduct the "employer-equivalent" portion of your self-employment tax (50% of it) from your adjusted gross income when calculating your federal income tax. This calculator automatically accounts for this deduction.
