How bonuses are taxed for freelancers: a practical guide
How bonuses are taxed explained for freelancers, with a worked example, a checklist and the mistakes to avoid.
Why this matters for freelancers
No employer withholds tax for freelancers, so every invoice should be treated as partly the tax authority's money. Getting the numbers right early avoids a painful bill at year-end.
Worked example
Here is the calculation with sample figures. Change any number in the Bonus Tax Calculator to run your own.
| Amount | $6,250.00 |
| Federal rate (%) | 22% |
| State rate (%) | 5% |
| Federal tax | $1,375.00 |
|---|---|
| State tax | $312.50 |
| Social Security and Medicare | $478.12 |
| Net amount | $4,084.38 |
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 | $18,750.00 |
| Federal rate (%) | 22% |
| State rate (%) | 5% |
| Federal tax | $4,125.00 |
|---|---|
| State tax | $937.50 |
| Social Security and Medicare | $1,434.38 |
| Net amount | $12,253.12 |

Key terms
- Deduction
- An amount subtracted from taxable income. It saves tax equal to the deduction times your marginal rate.
- Gross amount
- The amount after tax is added, which is usually what a consumer pays.
- Marginal rate
- The rate applied to the next unit of income. It decides how much of a raise or a deduction you keep.
- Taxable income
- Income left after allowances and deductions, on which the tax rates are applied.
- Zero rate
- A rate of 0% on a taxable supply. Unlike an exemption, the seller can usually still reclaim tax on costs.
A quick checklist for freelancers

- Add state tax and FICA.
