What is the Tax Calculator?
Estimate your federal income tax based on your income, filing status and standard deductions, using current tax bracket data. Enter your gross income and filing status to see your estimated taxable income, tax owed and effective tax rate.
This gives a fast estimate for budgeting and planning purposes. It applies the marginal tax bracket system correctly — meaning only the income within each bracket is taxed at that bracket's rate — but it can't account for every credit, itemized deduction or state-specific rule that applies to your actual return.

Questions people ask
How accurate is this tax calculator?
It's a solid planning estimate using real marginal brackets and the standard deduction, but it can't capture every credit, itemized deduction or state-specific rule on your actual return.
What is an effective tax rate?
Your total tax owed divided by your total income — it's always lower than your top marginal bracket because of how progressive brackets work.
Does this include state tax?
No, this estimates federal income tax only.
Is this calculator free?
Yes, free with no signup.
Does it include FICA (Social Security and Medicare)?
No, this covers federal income tax; FICA is a separate flat-rate payroll tax.
