About This Calculator

This calculator estimates your total federal income tax liability using current IRS tax brackets and the standard deduction. It's a quick summary tool — for a full breakdown of how much tax falls into each bracket, see the Income Tax Calculator.

How This Is Calculated

Taxable Income = Gross Income − Deduction; Tax = sum of marginal brackets applied to taxable income

An $85,000 single-filer income with the standard deduction has about $68,900 taxable income and roughly $10,655 in federal tax.

Assumptions

  • Uses 2026 federal tax brackets and standard deduction amounts (IRS Rev. Proc. 2025-32).
  • Does not include tax credits (child tax credit, EITC, etc.), which would reduce tax owed further.
  • Does not include state or local income tax.

Frequently Asked Questions

Use whichever is larger — the standard deduction is a fixed amount based on filing status, while itemizing totals specific expenses like mortgage interest, state/local taxes (capped), and charitable donations. Most filers take the standard deduction since it now exceeds itemized totals for many households.
