About

Basefigure is a set of free calculators. Money tools use the rate you type. VAT, GST, and US sales tax pages each use one standard rate stored in the site, not a live lookup when you calculate.

Statewide US sales tax rates come from the Tax Foundation compilation of state rates as of January 1, 2026. VAT and GST standard rates are checked against the national tax authority named on each page. City, county, and reduced rates are not calculated.

The figures are estimates for planning. They are not tax, legal, or financial advice. Questions about a page can go to [email protected].
