How the calculator works

US creators on OnlyFans are self-employed, so tax is owed on profit: payouts minus business expenses. Two taxes apply. The IRS self-employment tax is 15.3% on 92.35% of net profit (12.4% Social Security, capped at $184,500 of earnings in 2026, plus 2.9% Medicare), with an extra 0.9% Medicare above $200,000 for single filers or $250,000 for joint filers. Income tax then applies to profit after deducting half of the self-employment tax.

  • Net profit = payouts − business expenses.
  • Self-employment tax = profit × 92.35% × 15.3% (Social Security part capped at $184,500), zero if profit is under $400.
  • Income tax = (profit − half of self-employment tax) × your income tax rate.
  • Quarterly payment = total tax ÷ 4.
