How this calculation works

  • Combines SE tax and income tax estimates to get total tax.
  • Applies a state tax rate and subtracts credits if entered.
  • Adds an optional buffer to recommend a set-aside rate.
  • Translates annual totals into quarterly and monthly targets.

Common mistakes and caveats

  • State tax input is a flat estimate and may not match brackets.
  • Credits and deductions can materially change the set-aside rate.
  • Recalculate when income changes during the year.
