How federal income tax is calculated

Federal income tax is not charged on all your income. First the standard deduction ($16,100 single, $32,200 married filing jointly in 2026) is taken off. The rest is taxed in layers, from 10% up to 37%, and credits like the Child Tax Credit come off the result.

Example: a single filer earning $75,000 has $58,900 of taxable income and pays $7,670 in federal tax. That is 10.2% of income, not the 22% top bracket.

Federal Income Tax Formula (2026)

Three steps from income to the tax you owe.

Taxable Income = Income − Standard Deduction

Example:

Single filer, $75,000

$75,000 − $16,100
= $58,900 taxable

Variables:

Standard deduction - $16,100 single · $32,200 married jointly · $24,150 head of household

Tax = 10% × first slice + 12% × next slice + 22% × next slice ...

Example:

$58,900 taxable, single

10% × $12,400 + 12% × $38,000 + 22% × $8,500
= $7,670 federal tax

Variables:

Brackets - 10%, 12%, 22%, 24%, 32%, 35%, 37%

Tax Owed = Tax − Credits

Example:

Married filing jointly, $75,000, two children

$4,640 − $4,400
= $240 federal tax owed

Variables:

Child Tax Credit - $2,200 per child under 17

These formulas provide the mathematical foundation for the calculations. Actual results may vary based on rounding, compounding frequency, and specific lender policies.

Federal income tax FAQs

Quick answers about federal tax rates, credits and refunds.

How much federal tax do I pay on $50,000?

A single filer earning $50,000 in 2026 pays about $3,820 in federal income tax after the $16,100 standard deduction. That is an effective rate of 7.6%, even though the top bracket reached is 12%.

How much federal tax do I pay on $100,000?

About $13,170 for a single filer, an effective rate of 13.2%. Married couples filing jointly on the same income pay $7,640.

What is the difference between effective and marginal tax rate?

Your marginal rate is the bracket your last dollar falls in. Your effective rate is your total tax divided by your income. Because lower brackets apply to your first dollars, the effective rate is always lower than the marginal rate.

How much is the Child Tax Credit in 2026?

$2,200 for each child under 17. It is subtracted directly from your tax. It starts to shrink above $200,000 of income ($400,000 for married couples filing jointly).

Will I get a refund or owe money?

Compare your total tax with the federal tax already withheld from your paychecks (box 2 of your W-2, or year-to-date on your pay stub). Enter that amount in the calculator: if more was withheld than you owe, you get the difference back.

How do I change how much federal tax comes out of my paycheck?

Give your employer a new Form W-4. Our W-4 calculator shows what to enter so your withholding matches your actual tax.
