What We Do

Sales Tax Calculator is a free online tool that helps you look up combined state, county, and city sales tax rates by address. All calculations and lookups run instantly in your browser — no account required, no personal data collected.

Data Sources

Our data comes from authoritative public sources, including:

• State department of revenue tax rate databases
• County and municipal tax authority publications
