Sourdough 2025 / 2026

Save 25 to 30 percent of every payout

You owe both self-employment tax and regular income tax. Plan for both.

  1. Self-employment tax is 15.3 percent of your profit (12.4 percent Social Security plus 2.9 percent Medicare).
  2. Federal income tax adds another 10 to 24 percent on top. California adds 1 to 9.3 percent for most gig drivers.
  3. Open a separate bank account for taxes. Move 25 percent of every payout in. Pay from there.
  4. Quarterly is safer than waiting until April.
