Income tax calculator

How it’s calculated

Federal tax follows the 2025 and 2026 IRS rate schedules and inflation amounts (Rev. Proc. 2024-40 and 2025-32) as changed by the 2025 tax law: the higher standard deduction, the $2,200 child tax credit, the $40,000 state and local tax cap, and the new deductions for tips, overtime, car loan interest and seniors. It includes self-employment tax, the 0.9% Additional Medicare tax, the 3.8% net investment income tax, the earned income credit and a simplified alternative minimum tax.

Each state uses its own starting point, deductions, exemptions, rates and main credits, taken from that state's instructions, tax tables or law. Where a state had not yet published a 2026 figure on the date checked, the calculator uses the latest official figure and says so in the results. Local taxes cover city, county and school district income taxes where the state or city publishes the rates.

Items a state allows that need details this form does not ask for are listed under each result as not included.

Worked example

A single filer in Texas with $75,000 of wages in 2025 owes $7,949 of federal income tax after the $15,750 standard deduction, plus $5,738 of Social Security and Medicare, and no state income tax.
