Sales Tax Calculator – US State and Local Sales Tax
Add US sales tax to a price or work out the price before tax from a receipt total. Every state’s base rate is built in, and you can add your city, county or district rate to get the exact total you’ll pay at checkout.
How to use the sales tax calculator
- Enter the amount.
- Choose whether it is before tax (a shelf price) or including tax (a receipt total).
- Pick your state.
- Add your local rate — the county, city or district rate on top of the state rate.
You’ll see the sales tax, the total or the pre-tax price, and the state and local parts of the rate.
Sales tax formulas
The rate is the combined rate: state plus local.
Worked examples
- $100 in California with a 1.25% local rate: combined 8.5%, tax $8.50, total $108.50.
- $50 in Texas at 6.25% state plus 2% local: combined 8.25%, tax $4.13, total $54.13.
- $1,000 laptop in Oregon: no sales tax — you pay $1,000.
- $54.13 receipt at 8.25%: price before tax = 54.13 ÷ 1.0825 ≈ $50.00.
Finding your local rate
Your state’s department of revenue publishes local rates, often with a look-up tool by address. Your receipt also shows the combined rate. Rates can change on 1 January, 1 April, 1 July or 1 October, so check if you’re budgeting for a large purchase.
What’s taxed and what isn’t
- Groceries: exempt in most states, taxed at a reduced rate in some.
- Clothing: exempt in a few states, such as Pennsylvania and New Jersey, sometimes with limits.
- Prescription drugs: exempt almost everywhere.
- Services: taxed in some states, not in others.
- Cars: usually taxed, often with the trade-in value deducted — the auto loan calculator handles this.
- Online purchases: most online retailers now collect sales tax based on your delivery address.
Sales tax holidays
Several states run tax-free weekends, often for back-to-school shopping, energy-efficient appliances or emergency supplies. If you’re planning a big purchase, it can be worth checking your state’s calendar.
Use tax
If you buy something from a seller that doesn’t collect your state’s sales tax — for example from another state or another country — many states expect you to pay “use tax” at the same rate yourself, often on your state income tax return. It is easy to overlook for large purchases such as furniture, electronics or equipment for a small business.

Frequently asked questions
How do I calculate sales tax?
Multiply the price by the combined sales tax rate and divide by 100. For $100 at 8.5%, the tax is $8.50 and the total is $108.50.
How do I find the price before tax?
Divide the total by (1 + rate ÷ 100). A $108.50 receipt at 8.5% is 108.50 ÷ 1.085 = $100 before tax.
Which states have no sales tax?
Alaska, Delaware, Montana, New Hampshire and Oregon have no statewide sales tax. Some Alaskan cities and boroughs still charge a local sales tax.
Which state has the highest sales tax?
California has the highest statewide base rate at 7.25%. Once local taxes are added, combined rates in some cities in Louisiana, Tennessee, Arkansas, Washington and Alabama are among the highest in the country, often above 9%.
Why is my receipt different from the state rate?
Counties, cities and special districts add their own rates on top of the state rate. Some items are also taxed at a different rate or exempt — groceries and prescription medicine are exempt or reduced in many states.
Is sales tax the same as VAT?
No. US sales tax is added only at the final sale to the consumer and shown separately on the receipt. VAT, used in the UK, EU and much of the world, is charged at each stage and is usually included in the shelf price.
