Add sales tax to a price or take it out of a total, with your state rate plus local rate
Estimates only, not financial advice. What you type stays on your device. Checked against sources on 7 Oct 2026.Sales tax is the price times the rate, rounded to the cent. At a 7% example rate, $49.99 carries $3.50 of tax for a $53.49 total. To take tax out, divide the total by 1 plus the rate: $53.49 divided by 1.07 is $49.99 before tax.
7% is filled in as an example only. Use the combined rate on your receipt or from your state's revenue department, or pick your state above.

2026 · Rates and rules read from the sources listed on this page (the earliest on 7 Oct 2026); they may have changed since.
Under "Work out", keep "Add tax to a price" selected.
Type the "Price of one item, before tax" in dollars.
Pick your "State" to fill in its statewide rate, then add your city or county rate; or keep "Type the combined rate myself" and replace the example 7%.
Set "Quantity" if you are buying more than one item.
Read the "Sales tax" and "Total", then press "Share result" to copy a link.
The Sales Tax Calculator works both ways. Add tax takes a price before tax, an optional quantity and a rate, and gives the tax and the total. Remove tax takes a total that already includes tax and gives the price before tax and the tax inside it.
Your state's rate, plus your local rate. Pick a state and the page fills in its 2026 statewide rate, read on that state's revenue department page on 7 October 2026 and linked under Sources: 6.25% in Texas, 7.25% in California (6% state plus 1.25% local charged everywhere), 4% in New York. Counties, cities and special districts often add their own rates, which depend on the exact address, so type yours in "Add your city/county rate (local)". Alaska, Delaware, Montana, New Hampshire and Oregon have no statewide sales tax. Or skip the list and type the combined rate yourself; the 7% filled in then is only an example.
Rounding to the cent. Tax is worked out in whole cents and rounded to the nearest cent, with half a cent rounded up: $100 at 8.875% is $8.875, shown as $8.88. Your state's own rounding rule decides the cent on a real receipt.
Per item or on the total. With a quantity above one, the tax on the whole line can differ from the tax rounded on one item and multiplied. Three items at $0.99 and 7.25% carry 22 cents of tax on the total but 21 cents when each item is rounded first. Both figures are shown, because sellers do it either way.
Removing tax exactly. Dividing a total by 1 plus the rate rarely gives a whole number of cents, so the calculator finds the whole-cent price whose tax brings it to your total exactly. Some totals cannot come from any price (at 50%, a $1.00 item totals $1.50 and a $1.01 item $1.52, so nothing totals $1.51); the page says so and shows the nearest prices either side.
What the calculator does not do: it does not look up local rates by address or ZIP code, it does not know which items your state exempts (groceries and medicine often are), and it does not handle use tax, excise taxes, tips or shipping. It is not tax or filing advice.
Multiply the price by the rate and round to the cent. At 7%, $49.99 times 0.07 is $3.4993, which rounds to $3.50, so the total is $53.49. For a three-decimal rate such as 8.875%, multiply by 0.08875. The calculator works in whole cents so the result never drifts by a fraction.
Divide the total by 1 plus the rate. At 7%, $53.49 divided by 1.07 is about $49.9906, so the price before tax is $49.99 and the tax is $3.50. The calculator checks that the whole-cent price really taxes back to your total, and says when no price can.
Use the combined rate where the sale happens: the state rate plus any county, city or district rate. Pick your state and the page fills in its 2026 statewide rate from the state revenue department; then add your local rate from a receipt or the state's rate lookup. With no state picked, the 7% shown is only an example.
Rounding. A store may round the tax on each item and add the pennies, or work out tax once on the whole bill, and the two can differ by a cent or more. Three items at $0.99 and 7.25% give 21 cents one way and 22 cents the other. Both are shown here when the quantity is above one.
Not always. States choose what is taxed, and many exempt or reduce the rate on groceries, prescription medicine or clothing, while a few states have no statewide sales tax at all. Check your state's revenue department for what applies. The calculator applies the one rate you enter to the whole amount.
No. The page knows each state's statewide rate, read on the state's own revenue department page on 7 October 2026, but local rates depend on the exact address, so it never guesses one. Type your city, county or district rate in the local box. New Mexico's 2026 figure is marked check source.
