opentaxrate

Sales tax for any US address

Rates based on public data from state tax agencies. See sources

or try one

One address, every part of its rate, and the lines that decided it.

  • Address-level, not ZIP

    A ZIP that crosses a city line isn't averaged or rounded down; the street decides.

  • Dated back to 2020

    Ask for a sale's date and get the rate in force that day, back to 2020 for most states.

  • Refuses instead of guessing

    Near a city line, or when geocoders disagree, it returns the candidate rates. Missing data is never read as zero.
