About Us
Our mission: make tax calculations free, instant, and accessible to everyone.
Why We Built This
We built salestaxreversecalculator.com because calculating the original price before tax shouldn't require a math degree. Whether you're a shopper checking a receipt, a freelancer tracking expenses, or an accountant separating revenue from tax — our free tool gives you an instant, accurate answer.
No Signup. No Fees. No Data Collected.
All calculations happen directly in your browser using JavaScript. We never send your price data to any server. There are no accounts, no cookies tracking your calculations, and no selling your data. What you calculate stays on your device.
Built for Everyone
Whether you're in Alabama or Wyoming, Ontario or Queensland, London or Mumbai — our calculator works for you. We support all 50 US states with combined rates, all 13 Canadian provinces and territories, European VAT, and any custom rate worldwide.
Constantly Updated
Tax rates change. We monitor US state rate updates and refresh our database regularly to ensure you always have accurate combined average rates at your fingertips. Our last comprehensive rate review was in 2026.
