Formula

Your marginal tax rate tells you exactly how much tax you pay on the next dollar you earn. When you receive a bonus, raise, or freelance income, the marginal rate determines the tax cost of that extra money. This calculator computes the actual tax on additional income, including any bracket shifting.

Tax on additional = Tax(income + extra) - Tax(income)

Percentage: The percentage value you want to apply

Number: The original number or value

Result: The calculated result

How It Works

1Enter your current annual income.
2Enter the additional income amount (bonus, raise, side income).
3Select your filing status.
4The calculator computes tax before and after the additional income.
5The difference shows the exact tax cost of the extra earnings.

Frequently Asked Questions

A bonus itself may be withheld at a flat 22% by your employer, but when you file your return, it is taxed at your marginal rate based on your total income. If you are already in the 22% bracket, the bonus is simply taxed at 22%.

Marginal rate is the tax on the next dollar earned. Effective rate is your total tax divided by total income. A $10,000 bonus taxed at 22% marginal rate does not mean your overall rate jumps to 22%.

Increase pre-tax contributions (401k, HSA) to keep taxable income lower, time income across tax years, or invest in tax-advantaged accounts to defer taxation on additional earnings.
