How It Works
Estimates net payout on performance, signing, or annual bonuses using the standard 22% federal supplemental wage withholding rate and state supplemental tables.
Calculation Example
A $15,000 corporate bonus incurs $3,300 federal withholding (22%), $930 Social Security (6.2%), $217.50 Medicare (1.45%), and $990 state withholding (6.6%), yielding a net bonus check of $9,562.50.
Frequently Asked Questions
Because supplemental wage withholding uses a flat 22% rate without applying standard deductions or lower 10% and 12% brackets, the initial deduction rate is typically higher.
