Combined rates are averages of the local taxes within a state, so your exact address may differ. For an exact figure, check the rate published by your state’s Department of Revenue.

To calculate sales tax, multiply the pre-tax price by the tax rate as a decimal, then add the result to the price. A $50 item at 8.25% is $50 × 0.0825 = $4.13 in tax, for a total of $54.13. The arithmetic is simple; the hard part is knowing which rate applies. Sales tax in the United States is levied by states, counties, cities and special districts all at once, so the rate at the register is the sum of several layers and can change a few miles down the road. This calculator does the arithmetic and gives you a starting rate: pick a state and it fills in the combined state-plus-average-local rate, or type your exact rate if you know it. Every rate on this page comes from the Tax Foundation's July 2026 figures, and the full table for all 50 states and DC is below.
Sales tax is a consumption tax collected by the seller at the point of purchase and passed on to the state. Unlike VAT, which is charged at every stage of production, US sales tax is charged once, on the final retail sale. Five states levy no statewide sales tax at all — Alaska, Delaware, Montana, New Hampshire and Oregon — though Alaska lets its boroughs charge their own, which average 1.82%. Among the states that do levy one, the statutory rate runs from Colorado's 2.90% to California's 7.25%. Local add-ons change the picture completely: Colorado's average local rate is 4.99%, which lifts its combined rate to 7.89% and puts it above several states with a higher base. Louisiana has the highest combined rate in the country at 10.13%.
Sales Tax Formula
Work out what a purchase actually costs before you commit to it.
See how much of a big-ticket price is tax in one state versus another.
Confirm a retailer charged the correct rate on something you already bought.
Add the right tax to a customer quote, or quote a tax-inclusive price and show the split.
Separate the tax line from an all-in total when the receipt does not break it out.
Estimate the tax a retailer will add at checkout for your delivery address.
See the real total before you buy, so a budget set on shelf prices is not short by 8% at the register.
Pick a state and the combined state-plus-average-local rate fills in, from Tax Foundation figures effective 1 July 2026.
The same purchase costs measurably more in Louisiana than in Oregon. The table below shows every state side by side.
Switch to tax-inclusive mode to pull the tax back out of a total and confirm you were charged the right amount.
Every result shows the formula and each step, so you can check the arithmetic or learn the method.
Multiply the price by the tax rate written as a decimal, then add it to the price. At 8.25%, a $50 item carries $50 × 0.0825 = $4.13 of tax and costs $54.13 in total. To go the other way and find the tax inside a total, divide the total by 1 plus the rate.
Five states levy no statewide sales tax: Alaska, Delaware, Montana, New Hampshire and Oregon — remembered as the NOMAD states. Alaska is the exception that matters: it has no state rate but permits local ones, which average 1.82%, so a purchase in Alaska is not necessarily tax-free.
By statutory state rate, California is highest at 7.25%. By combined state and average local rate — which is what you actually pay — Louisiana is highest at 10.13%, followed by Tennessee at 9.61%, Washington at 9.57%, Arkansas at 9.48% and Alabama at 9.46%.
The state rate is set by the legislature and applies everywhere in the state. The combined rate adds the local taxes charged by counties, cities and special districts, weighted by population. New York’s state rate is 4.00% but its combined rate is 8.54%, because local taxes add most of the burden. The combined figure is an average, so your address can be above or below it.
Counties, cities and special districts can each levy their own sales tax on top of the state rate, so the total changes at every jurisdiction boundary. Louisiana allows local rates up to 7.00% on top of its 5.00% state rate. New Jersey runs the other way: its Urban Enterprise Zones charge half the state rate, which pulls its average local rate slightly negative and its combined rate just below its statutory 6.63%.
Usually yes. Since the Supreme Court’s 2018 decision in South Dakota v. Wayfair, states may require out-of-state sellers to collect sales tax once they pass an economic-nexus threshold — commonly $100,000 in sales or 200 transactions into that state. Tax is charged at the rate for the delivery address, not the seller’s location.
Exemptions are set state by state. Groceries, prescription drugs and clothing are the most commonly exempted categories, though many states tax groceries at a reduced rate rather than exempting them outright. Several states also run temporary sales-tax holidays, typically for back-to-school or disaster-preparedness supplies.
Switch this calculator to tax-inclusive mode, or divide the total by 1 plus the rate. A $108.25 total at 8.25% is $108.25 ÷ 1.0825 = $100.00 before tax, so $8.25 was tax. Note that subtracting 8.25% from the total is not the same calculation and gives the wrong answer.
