How It Works

How progressive tax brackets work

The U.S. federal income tax system uses progressive brackets. This means your income is not all taxed at one rate. Instead, each portion of your taxable income is taxed at the rate for that bracket.

For 2024, the single filer brackets are:

Rate	Taxable income range
10%	$0 to $11,600
12%	$11,601 to $47,150
22%	$47,151 to $100,525
24%	$100,526 to $191,950
32%	$191,951 to $243,725
35%	$243,726 to $609,350
37%	Over $609,350

Before applying brackets, subtract the standard deduction ($14,600 for single, $29,200 for married filing jointly, $21,900 for head of household) from gross income to get taxable income.

Worked example

For a single filer earning $75,000: Taxable income = $75,000 - $14,600 = $60,400.

• 10% on the first $11,600 = $1,160
• 12% on $11,600 to $47,150 = $4,266
• 22% on $47,150 to $60,400 = $2,915

Estimated total federal tax = $1,160 + $4,266 + $2,915 = $8,341. Effective rate = $8,341 / $75,000 = 11.1%. The marginal rate (the rate on the last dollar earned) is 22%.

Frequently Asked Questions

What is the difference between marginal and effective tax rate?

The marginal rate is the tax rate applied to your last dollar of taxable income. The effective rate is your total tax divided by your total gross income. Because of the progressive bracket system, the effective rate is always lower than the marginal rate. For example, a single filer in the 22% bracket typically has an effective rate between 10% and 15%.

Does this include state income tax?

No. This calculator shows federal income tax only. State income taxes vary by state and may have their own bracket structures, flat rates, or no income tax at all. Your total tax burden includes both federal and state taxes plus FICA (Social Security and Medicare).

What is the standard deduction for 2024?

For 2024, the standard deduction is $14,600 for single and married filing separately, $29,200 for married filing jointly, and $21,900 for head of household. The standard deduction reduces your taxable income before tax brackets are applied.

How does the 'what if I earn more' analysis work?

The marginal impact section shows the estimated additional federal tax on an extra $1,000 of income. This amount equals your marginal tax rate applied to $1,000. If you are in the 22% bracket, an extra $1,000 would result in approximately $220 more in federal tax.

Are tax brackets adjusted for inflation?

Yes. The IRS adjusts tax bracket thresholds and the standard deduction annually for inflation. The amounts shown here are for the 2024 tax year. Future years will have slightly different thresholds.
