What is Sales Tax?
Sales tax is a consumption tax imposed by governments on the sale of goods and services. It's calculated as a percentage of the purchase price and collected by the seller at the point of sale. In the United States, sales tax is administered at the state level, and many local jurisdictions (counties, cities, special districts) add their own taxes on top of state rates.
Sales Tax = $100 × 0.085 = $8.50
Total Price = $108.50

Sales Tax vs VAT (Value Added Tax) — How International Tax Calculators Differ
Sales tax is collected only at the final point of sale to the consumer. VAT (Value Added Tax) is collected at every stage of production and distribution. Most countries outside the US use VAT (10-25%), while the US uses retail sales tax. If you're shopping internationally, be aware that prices often exclude VAT, which is added at checkout — use a VAT calculator rather than a US sales tax calculator for international purchases.

Are groceries taxed? Will this sales tax calculator show tax on food?
Most states exempt unprepared groceries from sales tax. When using our sales tax calculator, enter "0%" for groceries in exempt states. However, some states tax groceries at a reduced rate (Illinois 1%, Missouri 1.225%, Tennessee 4%, Utah 1.75%, Virginia 1.5% local only). Prepared food (restaurants, deli items, hot prepared foods) is generally taxable in all states — your tax calculator will apply the full rate to these items.
Is clothing taxable? How does this sales tax calculator handle clothing?
Clothing taxability varies by state — use our sales tax calculator with your local sales tax rate. Most states tax clothing, but some exempt it (Minnesota, New Jersey, Pennsylvania, Rhode Island, Vermont). Others have tax holidays for back-to-school clothing. Tax treatment often differs for items over certain prices (luxury clothing tax). Our tax calculator works for any scenario — just enter the correct rate.
Do I pay sales tax on online purchases? Can this sales tax calculator estimate it?
Yes, following a 2018 Supreme Court decision (South Dakota v. Wayfair), states can require online retailers to collect sales tax even without a physical presence. Most major online retailers now collect sales tax in all 45+ states with sales tax. Use our sales tax calculator to estimate what you'll pay — simply enter the purchase price and your local sales tax rate.
What is use tax? How does this tax calculator relate to use tax?
Use tax is the counterpart to sales tax. If you buy something tax-free online or out-of-state and use it in your home state, you owe use tax equal to what sales tax would have been. Our sales tax calculator can help you calculate what you owe — just enter the purchase price and your local tax rate. Most states have a line on income tax returns to report use tax, though compliance is very low.
Why do some cities have higher sales tax? How does this sales tax calculator handle local rates?
Local governments (counties, cities, transit districts, stadium districts) often add their own sales tax to fund specific services like transportation, schools, or sports stadiums. For example, Chicago has a 10.25% combined sales tax rate due to multiple local add-ons. Our sales tax calculator can handle any combined rate — just enter your total state + local rate for accurate results.
How do I find my exact local sales tax rate for this calculator?
To use our sales tax calculator accurately, find your exact combined rate by: checking your state's department of revenue website, looking at a recent receipt (shows the rate charged), asking the retailer, or using our calculator's ZIP code lookup feature. Many states have online tax rate lookup tools by address — use those rates in our tax calculator.
Is sales tax refundable for tourists? Will this sales tax calculator help?
In the US, generally no. Unlike many other countries (VAT refunds for tourists), the US does not have a national sales tax refund system for visitors. Our sales tax calculator helps you understand what you'll pay, but cannot help with refunds. A few states (Texas, Louisiana) have limited refund programs for international visitors, but the process is complex.
Are digital goods taxable? How does this sales tax calculator handle streaming services?
Increasingly yes. Many states now tax e-books, streaming services (Netflix, Spotify), downloaded software, and cloud services — use our sales tax calculator with your local tax rate. Each state defines digital goods differently, so sales tax rates and rules vary significantly. Our tax calculator works for any taxable digital purchase — just enter the price and your applicable rate.
How does sales tax affect large purchases? Should I use this sales tax calculator for cars and boats?
On large purchases like cars, boats, RVs, or heavy equipment, sales tax can be substantial (thousands of dollars). ALWAYS use our sales tax calculator before making large purchases — for a $30,000 car at 8% tax, you'll pay $2,400 in tax! Some buyers consider purchasing in lower-tax states, but you generally owe tax where you REGISTER the vehicle, not where you buy it. Our tax calculator helps you budget accurately.
Is this sales tax calculator really free? Do you store my financial data?
Yes — this sales tax calculator is 100% free with no registration, no email signup, and no hidden fees. Use this tax calculator as many times as you want to calculate sales tax for different purchase amounts, tax rates, and states.
