How District of Columbia taxes your bonus paycheck
District of Columbia applies a supplemental withholding rate on bonus payments in addition to the federal 22% rate. The combined withholding can make a bonus look heavily taxed, though your final liability depends on total annual income.
Example: $10,000 bonus on $$75,000 salary
Single filer, biweekly pay — percentage method (22% federal supplemental + state supplemental rate).
| Gross bonus | $10,000 |
| Federal tax withheld | -$2,200 |
| State tax withheld | -$1,075 |
| Social Security | -$620 |
| Medicare | -$145 |
| Net bonus (percentage method) | $5,960 |
Aggregate method net bonus on this example: $6,207 (engine-computed delta vs salary-only withholding).
