Your 22% marginal rate is what a raise, bonus or extra deduction is taxed at — useful for decisions. Your 15.4% effective rate is what you actually pay overall, always lower because the early brackets tax income at lower rates.

How the marginal tax rate calculator (tax year 2026) works

Using the 2026 brackets, it finds the rate on your last dollar of taxable income — your marginal rate — alongside your effective (average) rate, and shows the tax on your next $1,000 of income.

Frequently asked

Questions about the marginal tax rate calculator (tax year 2026)

What is my 2026 marginal tax rate?

It is the bracket your last dollar falls into — one of 10, 12, 22, 24, 32, 35 or 37% for 2026. Enter your taxable income to see which applies.

Will a raise push all my income into a higher bracket?

No. Only the dollars above each 2026 threshold are taxed at the higher rate; the income below stays taxed at the lower rates.

How do I use the marginal rate?

To value decisions at the margin — a bonus, a pre-tax 401(k) contribution or a deduction are each worth your marginal rate, not your lower average rate.

Is the Marginal Tax Rate Calculator (Tax Year 2026) free to use?
