How bonuses are taxed explained for first-time filers, with a worked example, a checklist and the mistakes to avoid.
Why this matters for first-time filers
Filing for the first time can feel daunting, but most of it comes down to a few clear calculations.
Worked example
Here is the calculation with sample figures. Change any number in the Bonus Tax Calculator to run your own.
| Amount | $10,000.00 |
| Federal rate (%) | 22% |
| State rate (%) | 5% |
| Federal tax | $2,200.00 |
|---|---|
| State tax | $500.00 |
| Social Security and Medicare | $765.00 |
| Net amount | $6,535.00 |
How bonuses are taxed: how it works
Bonuses are taxed as income, but withholding often uses a flat supplemental rate, which can make the bonus look more heavily taxed than salary.
At filing time the bonus is simply part of total income.
A second example with larger figures
Scaling the inputs up shows how the result moves. Percentages stay the same, so the tax grows in proportion to the amount it is applied to.
| Amount | $30,000.00 |
| Federal rate (%) | 22% |
| State rate (%) | 5% |
| Federal tax | $6,600.00 |
|---|---|
| State tax | $1,500.00 |
| Social Security and Medicare | $2,295.00 |
| Net amount | $19,605.00 |
