Federal Income Tax Calculator (US)

This calculator helps you estimate US federal income tax, effective tax rate, and take-home income using clear inputs and an automatic result breakdown.

Federal income tax is progressive, which means different parts of your income can be taxed at different rates. Your top marginal rate is not the same as your effective tax rate, and confusing the two can make tax planning feel more expensive than it really is.

Use this for planning, comparison, and general understanding. Actual tax can vary because of filing status, deductions, credits, payroll treatment, additional income, state tax, local tax, and current IRS rules.

Suppose a single filer earns $75,000 and has a standard deduction of $14,600. Their taxable income would be about $60,400 before considering any other adjustments or credits.

That taxable income does not all get taxed at one rate. The first slice is taxed at the lowest bracket, the next slice at the next bracket, and so on. This is why moving into a higher tax bracket does not mean all of your income is suddenly taxed at that higher rate.

The calculator is useful for comparing scenarios such as a raise, bonus, deduction change, retirement contribution, or filing status change. It gives a planning estimate, not a filed return.

Your marginal tax rate is the rate that applies to the next dollar of taxable income. Your effective tax rate is total federal income tax divided by total income. The effective rate is usually lower than the marginal rate.

This distinction matters when evaluating overtime, side income, bonuses, or retirement contributions. A deduction usually saves tax at your marginal rate, while your overall tax burden is better described by your effective rate.

Common differences include tax credits, itemized deductions, pre-tax retirement contributions, health savings account contributions, self-employment income, capital gains, student loan interest, dependents, and filing status.

State and local taxes are separate from federal income tax. Payroll taxes such as Social Security and Medicare are also separate, so take-home pay may be lower than a federal-income-tax-only estimate suggests.

Use this calculator to estimate US federal income tax from annual income, filing status, and an optional simplified standard deduction.

The component applies built-in federal bracket logic after the deduction, then shows estimated federal tax, taxable income, marginal rate, effective rate, and income after federal tax.

It does not calculate state tax, payroll tax, local tax, credits, AMT, self-employment tax, capital gains rates, tax withholding, or itemized deduction details.

Use tax bracket us when you want a manual deduction field and the marginal bracket as the primary result.

Use tax withholding after this page when the question is whether payments or withholding cover expected annual tax.

Treating the federal estimate as full take-home pay. State tax, payroll tax, benefits, retirement contributions, and withholding timing are outside this component.

Assuming the standard deduction default is current for every tax year without checking official IRS values.

Expecting tax credits to be included. Credits such as Child Tax Credit or education credits need separate treatment.

Using this page for capital gains, qualified dividends, AMT, or self-employment tax without separate calculators.

Confusing federal tax owed with withholding. Withholding is a payment method, not the tax liability calculated here.

Example: enter $60,000 annual income, single filing status, and leave the standard deduction toggle on.

The calculator subtracts the simplified standard deduction, applies federal brackets to taxable income, and shows estimated federal tax.

It also shows marginal rate, effective rate, and income after federal tax before other tax or payroll layers.

Turn off the standard deduction toggle only when you want to model income without that deduction or handle a deduction elsewhere.

Use standard deduction or itemized vs standard deduction when deduction assumptions need more detail.

Use child tax credit after estimating tax before credit if dependent credits matter.

Use state tax, payroll tax, social security tax, and medicare tax for non-federal-income-tax layers.

Use estimated tax when the next question is how to size payments after an annual tax estimate.

Check whether filing status, deduction amount, and bracket table match the tax year being modelled.

Check whether credits, AMT, self-employment tax, capital gains, state tax, or payroll tax are material.

Check whether you need tax owed, withholding, or take-home pay, because each requires a different calculator scope.

Rerun this federal income tax calculator when income, filing status, deduction choice, or tax year changes.

Recheck after a raise, bonus, job change, retirement contribution change, or dependent change if those affect income or deductions.

If this estimate differs from tax software, trace filing status, deduction, taxable income, bracket table, credits, and special income separately.
