Adding sales tax
Sales tax is price × tax rate ÷ 100, added to the price. Rates vary widely by state, county and city, so use your local combined rate for an accurate total.
Combined state and local rates
The rate you actually pay is the state rate plus county and city add-ons. That's why two towns in the same state can charge different totals — combined rates range from 0% in a few states to over 10% in some cities. Online orders are generally taxed at the rate where the item is shipped.
Working backward from a total
To find the pre-tax price from a tax-included total, divide by 1 + the rate (for 8% tax, divide by 1.08). The difference is the tax. This is handy for expense reports and reconciling receipts where only the grand total is printed.
Sales Tax Calculator: frequently asked questions
How do I calculate sales tax?
Multiply the price by your sales tax rate (as a percent), then add it to the price for the total.
What sales tax rate should I use?
Use your local combined rate (state + county + city). It can range from 0% to over 10% depending on location.
How do I find the price before tax from a total?
Divide the total by 1 plus the tax rate as a decimal. If a receipt total is $54.00 at an 8% rate, the pre-tax price is $54.00 ÷ 1.08 = $50.00, making the tax $4.00.
