Sales Tax Calculator
Add or remove US sales tax from a price and see the tax amount and total.
This sales tax calculator adds tax to a price or strips it back out again. Use 'Add tax' when you have a pre-tax amount and want the total a customer pays, or 'Remove tax' when you have a tax-inclusive total and need to find the original price and the tax portion.
Sales tax is applied as a simple percentage of the pre-tax price. The calculator breaks the figure into the tax amount, the pre-tax price and the total so you can use it for receipts, invoices, expense reports or quick checks at the register.

Frequently asked questions
How do I remove sales tax from a total?+
Divide the tax-inclusive total by (1 + rate ÷ 100) to get the pre-tax price, then subtract that from the total to find the tax. The 'Remove tax' mode does this for you.
Is sales tax the same everywhere?+
No. Rates vary by country, state, county and city, and some items are taxed differently or exempt. Enter the exact combined rate that applies to your purchase.
What is the difference between sales tax and VAT?+
Sales tax is charged once at the final point of sale, while VAT is collected in stages along the supply chain. The math for a single transaction is similar, but the systems differ — use the VAT calculator for VAT-inclusive pricing.
