Tip: The “Remove Tax” mode is useful when a receipt shows a tax-inclusive price and you need to know the base price and the exact tax amount — handy for expense reports and VAT reclaims.
Our free sales tax calculator lets you add tax to any price or reverse-calculate to remove tax from a tax-inclusive total. Enter your amount and tax rate — or pick a quick preset for common US states and VAT rates — and instantly see the pre-tax price, tax amount, and final total broken down to the cent. Perfect for shoppers, small businesses, and expense reports.
Use 'Add Tax' mode. Enter the pre-tax price and the applicable tax rate percentage. The calculator instantly shows the tax amount and the final total you would pay.
Switch to 'Remove Tax' mode and enter the total amount that already includes tax, along with the rate. The tool back-calculates the original pre-tax price and the exact tax portion — useful for VAT reclaims and expense reports.
The base state rates range from 0% (Oregon, Montana, New Hampshire, Delaware) up to 7.25% (California). Most localities also add county or city taxes on top, so the final rate you pay can be higher. Use our Quick Rates presets as a starting point.
Sales tax is charged only at the final point of sale in the US, while VAT (Value Added Tax) is collected at each stage of production in Europe and many other countries. Both end up as a percentage added to the consumer price, so this calculator works for both.
