Sales Tax Calculator
Enter an amount and a ZIP code to get the combined state, county, and city sales-tax rate, the tax, and the total — or reverse it to back the tax out of a receipt.
Short answer
To find sales tax, multiply the price by your local combined rate (state + county + city). At a 9.5% rate, a $100 purchase has $9.50 tax and a $109.50 total. Rates vary by ZIP because counties and cities add their own. Enter your amount and ZIP above for the exact figure.

Rates as of 2026-Q3. Five states have no statewide sales tax (AK, DE, MT, NH, OR), though Alaska allows local rates. "Avg. combined" follows Tax Foundation methodology; your exact rate depends on the city and county — enter a ZIP in the calculator.
How sales tax is calculated
Your total sales-tax rate is the sum of the state rate plus any county and city rates for your address. Multiply the purchase price by that combined rate to get the tax, then add it to the price for the total. Because local rates differ, the same purchase can be taxed differently a few miles away — which is why this tool looks up the rate by ZIP code.
Reverse sales tax & car purchases
Switch to reverse mode to work backward from a tax-included total and see the pre-tax price and tax portion — handy for expense reports and receipts. Buying a car? Sales tax is generally charged at the combined rate where you register the vehicle, so enter the price and your home ZIP for an estimate.
How we calculate this
Every rate on this page comes from the same layered dataset the ZIP lookup uses — state base rates plus curated local rates:
- ZIP → jurisdiction. your ZIP code maps to a state and, where curated, a specific city rate; otherwise the state's average combined (state + local) rate applies as the representative figure.
- The tax. amount × combined rate = tax; amount + tax = total. Rates are the sum of state, county, and city components.
- Reverse sales tax. to back tax out of a receipt: pre-tax price = total ÷ (1 + rate). A $107.25 receipt at 7.25% was $100 before tax — dividing, not subtracting, is the part people get wrong.
Assumptions
- General merchandise rates — groceries, clothing, and prepared food carry special rates or exemptions in many states.
- ZIP codes don't align perfectly with tax jurisdictions; a street-level lookup from the state DOR is the authoritative rate.
- Rates are estimate-grade and re-verified quarterly — always charge customers the rate your state's DOR publishes.

Frequently asked questions
How do I calculate sales tax?+
Multiply the price by the combined sales-tax rate for your location. For example, on a $100 purchase at a 9.5% combined rate, the tax is $9.50 and the total is $109.50. The combined rate is your state rate plus any county and city rates. Enter an amount and a ZIP code above to get the exact tax and total.
Why is sales tax different by ZIP code?+
Sales tax is set by state, county, and city governments, and those combine differently across the country. Two towns in the same state can have different total rates because of local add-ons. That's why this calculator asks for a ZIP code — it looks up the combined state, county, and city rate for your area.
How does reverse sales tax work?+
Reverse sales tax works backward from a total that already includes tax to find the original pre-tax price and the tax portion. If a receipt shows $109.50 at a 9.5% rate, the pre-tax amount was $100 and the tax was $9.50. Switch to the reverse mode above to back out the tax from any total.
How much is sales tax on a car?+
Car sales tax is usually charged at the combined rate where you register the vehicle (often your home address), not where you buy it. On a $30,000 car at an 8% combined rate, that's $2,400 in sales tax. Some states also add title, registration, and documentation fees. Enter the car's price and your ZIP to estimate the tax.
Which states have no sales tax?+
Five states have no statewide sales tax: Delaware, Montana, New Hampshire, Oregon, and Alaska. Alaska is a special case — it has no state sales tax, but many local governments there charge their own, so the combined rate isn't always zero. Everywhere else, you'll pay a combined state-and-local rate.
Are these sales-tax rates exact?+
For major cities we use the actual combined rate; for other ZIP codes we show your state's representative combined rate. Because sales tax is legally tied to a precise address and a single ZIP can span multiple jurisdictions, treat the result as a close estimate and confirm the exact rate with your state's department of revenue for large or official purchases.
