Estimated taxes: A practical method is to reserve money from every payment, then calculate quarterly amounts. The self-employment tax rate shown here is 15.3%; add your own federal and state estimate based on your income bracket.

Reserve strategy
- Transfer a percentage of each payout into a tax savings account immediately.
- Increase the reserve rate during high-income months.
- Do not spend money set aside for the IRS.
Calculation notes
- Quarter due dates can move if they fall on weekends or holidays.
- If income is lumpy, update your estimate every quarter.
- Add state estimated tax separately if required where you live.
