What this means
Bonuses aren’t taxed more than other pay. The flat 22% is only withholding, a prepayment: your real tax is worked out on your return, where the bonus is taxed like the rest of your pay.
The 22% withheld is about right: the bonus adds roughly $1,100 to your federal tax for the year.
| Per year | |
|---|---|
| Bonus | $5,000.00 |
| Federal income tax | -$1,100.00 |
| Social Security | -$310.00 |
| Medicare | -$72.50 |
| South Carolina income tax (estimate) | -$331.55 |
| You keep | $3,185.95 |
