Tax Calculators
Estimate federal tax, marginal rates, self-employment tax and the savings from deductions.
Tax feels opaque, but the core machinery is simple: income, minus deductions, run through brackets, minus credits. These calculators estimate each step, so you can plan deductions and contributions and avoid a surprise at filing time.
Estimate your federal tax, see the gap between your marginal and effective rate, work out self-employment tax, and check that your paycheck withholding is set right.
Read the complete tax guideWhich tax year do these calculators use?
Each tax calculator is labeled by tax year, because brackets, the standard deduction and limits change annually. Choose the year you are filing for, and check current figures for the latest year before relying on them.
How accurate are the tax estimates?
They apply the year's brackets and standard amounts to the income you enter, so they are solid estimates. Your actual return depends on credits, deductions and details specific to your situation.
Are these tax calculators free?
Yes, all free with no sign-up. They give estimates for planning — for filing, use official forms or tax software, or consult a tax professional.
