About US Sales Tax Guide
Transparent, verified local tax data at zero cost. Learn about our mission and methodology.
Our Mission
US Sales Tax Guide was built with a single purpose: to give every American — whether a small business owner, e-commerce seller, consumer, or accountant — instant, free access to the exact sales tax rate for any location in the United States.
The US sales tax system is uniquely complex, with over 11,000 tax jurisdictions operating independently across 50 states. We believe navigating that complexity shouldn't require expensive software or a tax attorney. Our goal is to be the most comprehensive, authoritative, and genuinely useful sales tax resource on the internet.
Our Methodology
State DOR Sourcing
Every rate is sourced directly from official State Department of Revenue publications and tax tables.
Census Verification
Geographic boundaries and FIPS codes are verified against US Census Bureau TIGER/Line data sets.
Multi-Source QA
Combined rates are cross-checked against the Tax Foundation and Streamlined Sales Tax data points.
Quarterly Audits
Our database is refreshed quarterly with a last-verified timestamp displayed on every rate page.
What We Cover
Our Commitment to You
Always Free Access
US Sales Tax Guide will always be free. We believe access to open tax information is a public good, not a premium service reserved for those who can pay for software.
No Ads on Data Points
We only show ads in non-critical sidebar areas. Your tax rate data and calculations are never obscured or delayed by advertising overlays.
E-E-A-T Compliance
Every page includes data freshness indicators, official DOR source links, and clear disclaimers to ensure maximum transparency and authority.
