Why a bonus may look heavily taxed
Payroll withholding is not the same as final annual tax liability. A separately identified bonus may use the optional 22% federal supplemental-wage rate when the employer qualifies, while Social Security and Medicare are calculated separately.
Supported method
The calculator supports the aggregate method and the optional 22% method for separately identified supplemental wages up to $1 million. The excess over $1 million uses the mandatory 37% rate. Employer-specific eligibility is an assumption.
Bonus withholding example
A separately identified $5,000 bonus may use the optional 22% federal supplemental-wage method when the employer qualifies, producing $1,100 of federal withholding before Social Security and Medicare. Withholding is not final tax liability.
