Tax Bracket Calculator

Calculate your federal income tax, marginal rate, and effective tax rate. Understand how tax brackets work.

How Tax Brackets Work

The US uses progressive taxation — your income is split across brackets, and each portion is taxed at its own rate. Moving into a higher bracket does not tax all your income at the higher rate; only the dollars above the threshold.

2024 Federal Tax Brackets (Single)

10% on income up to $11,600
12% on $11,601 to $47,150
22% on $47,151 to $100,525
24% on $100,526 to $191,950
32% on $191,951 to $243,725
35% on $243,726 to $609,350
37% on income over $609,350

Marginal vs Effective Rate Example

If you earn $60,000 (single, no deductions for simplicity):

First $11,600 taxed at 10% = $1,160
$11,601-$47,150 taxed at 12% = $4,266
$47,151-$60,000 taxed at 22% = $2,827
Total tax: $8,253
Marginal rate: 22% (your highest bracket)
Effective rate: $8,253 ÷ $60,000 = 13.8% (your actual average rate)

Standard Deduction (2024)

Single: $14,600
Married filing jointly: $29,200
Head of household: $21,900

The standard deduction reduces your taxable income before brackets are applied. A single filer earning $60,000 has a taxable income of $45,400, dropping their effective rate further.

Common Ways to Reduce Taxable Income

401(k)/403(b) contributions: Up to $23,000/year ($30,500 if 50+) reduces taxable income dollar-for-dollar
Traditional IRA: Up to $7,000/year ($8,000 if 50+) may be deductible depending on income and employer plan
HSA contributions: Triple tax advantage — deductible going in, grows tax-free, withdrawals tax-free for medical expenses. $4,150 single / $8,300 family limit
Student loan interest: Deduct up to $2,500/year
Itemize deductions: Mortgage interest, state/local taxes (up to $10,000 SALT cap), and charitable donations. Only worthwhile if total exceeds the standard deduction

Common Tax Misconceptions

"A raise can push me into a higher bracket and I'll take home less" — False. Only the income above the new bracket threshold is taxed at the higher rate. A raise always increases take-home pay
"I should decline overtime to stay in my bracket" — False, for the same reason. More gross pay always means more net pay
"My tax bracket is my tax rate" — Your marginal rate applies only to your last dollar. Your effective rate (actual taxes ÷ total income) is always lower

Frequently Asked Questions

What is a marginal tax rate?

The tax rate on your last dollar of income. It's the rate for your highest tax bracket, not your overall tax rate.

What is effective tax rate?

Your total tax divided by total income. It's your actual average tax rate across all brackets.

How do tax brackets work?

Income is taxed progressively. Only income within each bracket is taxed at that rate, not your entire income.

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

No! Only the income above the bracket threshold is taxed at the higher rate. You always take home more with a raise.

What is taxable income?

Taxable income is gross income minus above-the-line deductions (such as retirement contributions) and the standard or itemized deduction. Tax brackets apply to taxable income, not gross income.

What is the difference between a tax deduction and a tax credit?

A deduction reduces your taxable income. A credit reduces your tax bill dollar-for-dollar. A $1,000 credit saves exactly $1,000 in taxes; a $1,000 deduction saves $220 if you are in the 22% bracket.

Can someone have a 0% federal effective tax rate?

Yes. A single filer whose gross income does not exceed the standard deduction has zero taxable income and owes no federal income tax. Low-income filers may also receive refundable credits that produce a negative effective rate.

Do long-term capital gains push ordinary income into a higher bracket?

No. Long-term capital gains sit on top of ordinary income for bracket purposes, but they are taxed at their own preferential rates (0%, 15%, or 20%). They do not push your wage income into a higher bracket.
