How this works
Tax = Price × (Tax Rate ÷ 100) Total = Price + TaxSales tax is calculated on the pre-tax price (the marked price before any tax is added). The total adds the tax to the original price. Combined state-and-local rates vary across the United States from 0% (Oregon, New Hampshire, Montana, Delaware, Alaska) to over 9.5% (Tennessee, Louisiana, Arkansas).
Examples
A $50 purchase in California (7.25%)
Tax is 50 × 0.0725 = $3.63. Total comes to $53.63. California has the highest state-level sales tax rate in the country at 7.25%, with most cities adding local tax that pushes the combined rate to 8.5–10%.
A $1,200 laptop in Texas (6.25% state, ~8% with local)
At the 6.25% Texas state rate, tax is $75 and total is $1,275. Most Texas cities and counties add local sales tax of 1.5–2%, pushing the combined rate to about 8.25%, which would yield $99 in tax and a $1,299 total.
No-sales-tax purchase in Oregon (0%)
Oregon, New Hampshire, Montana, Delaware, and Alaska have no state sales tax. A $100 purchase costs $100. Some Alaskan localities apply local sales tax, but these states have no statewide rate.
A restaurant meal in NYC (8.875%)
A $60 dinner in Manhattan with the 8.875% combined NYC sales tax rate has $5.33 in tax for a $65.33 total. Note that NYC restaurant meals are taxed at the standard sales tax rate; some prepared-food sales in other states have a different rate.
Common questions
Sales tax is calculated on the discounted price — the actual amount you are paying. If a $100 item is on sale for $80, you pay tax on $80, not on $100. This is true for both manufacturer coupons and store sales.
Combined state and local rates are published by your state's department of revenue. The Tax Foundation maintains an annual state-and-local-rate report. For an exact rate at a specific address, your state's online tax-rate lookup tool returns the combined rate for that location.
It varies by state. Most states tax tangible goods but exempt many services. Some states tax specific services (haircuts, lawn care, professional services) at different rates or not at all. Check your state's rules for any service-based purchase.
When combining state and local rates, several Tennessee, Arkansas, and Louisiana localities exceed 10%. Tennessee has the highest combined average state and local sales tax rate at about 9.55%. Five states (Oregon, New Hampshire, Montana, Delaware, Alaska) have no statewide sales tax at all.
Yes — since the 2018 Wayfair decision, states can require online sellers to collect sales tax based on the buyer's shipping address. Major retailers calculate the correct rate at checkout. Smaller sellers may or may not collect, in which case you may technically owe use tax to your state.
