How Bonus Take-Home Pay Is Estimated

Formula

Bonus - federal supplemental withholding - state estimate - FICA = estimated net bonus

Example

A $10,000 bonus starts with 22% federal supplemental withholding before state and FICA estimates.

Important limits

  • Federal supplemental withholding is not always your final tax liability.
  • State bonus withholding varies by state and employer payroll setup.
  • Your final refund or balance due depends on your full-year income, deductions, and credits.
