Enter your annual income and choose your filing status, and it applies the standard deduction and the progressive federal tax brackets to work out what you owe.
Because the tax system is progressive, only the income that falls inside each bracket is taxed at that bracket's rate. The calculator shows both your effective rate — the share of your total income paid in tax — and your marginal rate, which is the rate on your next dollar of income.
Note: this is a federal-only estimate for the 2024 tax year using the standard deduction and statutory brackets. It excludes tax credits, state and local taxes, and other adjustments.
How to use it
- 1Enter your annual income before tax.
- 2Choose your filing status: Single or Married filing jointly.
- 3The standard deduction for your status is subtracted automatically.
- 4Read your estimated federal tax, effective rate, marginal rate and after-tax income.
Frequently asked questions
Which tax year does this use?+
It uses the 2024 federal tax brackets and standard deductions: $14,600 for Single filers and $29,200 for Married filing jointly.
What is the difference between effective and marginal rate?+
The marginal rate is the tax rate on your last dollar of income — the bracket your taxable income lands in. The effective rate is your total tax divided by your total income, which is always lower because the lower brackets are taxed at lower rates.
Does this include state tax or credits?+
No. This is a federal-only estimate for tax year 2024. It does not include state or local income tax, payroll taxes, or credits and adjustments such as the Child Tax Credit, so your actual bill may differ.
