Understanding Self-Employment Tax

Self-employment tax is how self-employed individuals contribute to Social Security and Medicare. When you work for an employer, you and your employer each pay half of these taxes. When you're self-employed, you're responsible for both portions.

Components of Self-Employment Tax

  • Social Security tax: 12.4% of your net earnings up to the wage base limit ($160,200 in 2023)
  • Medicare tax: 2.9% of all your net earnings with no upper limit
  • Additional Medicare tax: 0.9% on earnings above certain thresholds ($200,000 for single filers)

Calculating Self-Employment Tax

Self-employment tax is calculated on 92.35% of your net business income. This adjustment accounts for the employer-equivalent portion of your self-employment tax. You can also deduct half of your self-employment tax when calculating your income tax.

Tax Planning for Self-Employed

  • Make quarterly estimated tax payments to avoid underpayment penalties
  • Consider a business structure like an S-Corporation which may reduce self-employment taxes
  • Maximize business deductions to reduce net earnings subject to self-employment tax
  • Set up a retirement plan like a SEP IRA or Solo 401(k) to reduce taxable income
