> Free US tax calculators for 2026: federal income tax, FICA, income tax for all 50 states and DC, local income tax for 3,672 city and county jurisdictions, and property tax for all 3,143 US counties. Every figure carries the document it was read from and the date it was verified.

The calculations are deterministic — rates in, arithmetic out. A language model is used only to explain figures it is given; it never computes one. Calculations run in the visitor's browser and no personal figures are stored.

## Citing this site

Figures are dated per parameter rather than per page, because state legislatures change rates mid-year and sometimes backdate them. When citing a figure, cite the verification date shown next to it. If a figure has not been read off a primary source, the page says so rather than implying it has.
