Sales Tax Calculator
Add sales tax to a price and see the tax amount and total.
Sales tax rates vary by state, county, and even city — this calculator does the arithmetic once you know your local rate, showing the tax amount and final total instantly.
Where to find your local rate
Combined state and local sales tax rates in the US range from 0% (a handful of states, like Oregon and Delaware, charge none) to over 10% in parts of some cities. Your state's Department of Revenue website is the most reliable source for your exact combined rate, since city and county add-ons vary within a single state.
Sales tax vs. VAT vs. GST
Sales tax (used in the US) is charged once, at the final point of sale to the consumer. VAT (common in the EU and UK) and GST (used in countries like Australia, India, and Canada) are charged at each stage of production but are usually already built into the displayed price. If you're calculating tax outside the US, our VAT Calculator or GST Calculator will fit your situation better.
Frequently asked questions
Is sales tax the same on every purchase?
No — many jurisdictions exempt or reduce tax on categories like groceries, prescription medication, or clothing under a certain price. Always check your local exemption rules for large purchases.
Why do two receipts from the same state show different tax rates?
Local (city/county) sales tax add-ons stack on top of the state rate, so the combined rate can differ by a few blocks depending on which taxing jurisdictions a store falls within.
