What Sales Tax Calculator Does

This sales tax calculator adds tax to a price or backs it out of a total you already paid, using the 2026 statewide base rate for all 50 states and the District of Columbia. Add your county and city rate — or type the exact combined rate from a receipt — and it shows the tax split between state and local, the pre-tax price and the total.

U.S. sales tax is layered. Forty-five states and DC charge a statewide rate, and most allow counties, cities and special districts to add their own on top, so two stores a few miles apart can charge different totals. Five states — Alaska, Delaware, Montana, New Hampshire and Oregon — have no statewide sales tax, though Alaska and some Montana resort towns allow local ones.

Rates here are the Tax Foundation’s published 2026 figures. The one scheduled mid-year change, the District of Columbia moving from 6.5% to 7% on October 1, 2026, is applied automatically based on today’s date.

Formula Used by Sales Tax Calculator

Adding sales tax

Tax = price × rate ÷ 100; Total = price + tax

Worked example

A $100 purchase at California’s 7.25% base rate.

  1. 100 × 0.0725 = 7.25

Result: $7.25 tax, $107.25 total.

Removing sales tax from a total

Price before tax = total ÷ (1 + rate ÷ 100)

Worked example

A $107.25 receipt at 7.25%.

  1. 107.25 ÷ 1.0725 = 100.00
  2. Wrong way: 107.25 − 7.25% of 107.25 = 99.47

Result: $100.00 before tax. Subtracting the percentage from the total undercounts by $0.53.

How to Read Your Result

Highest combined rates in 2026

Once average local taxes are added, the Tax Foundation ranks Louisiana highest at about 10.13%, followed by Tennessee (9.61%), Washington (9.57%), Arkansas (9.48%) and Alabama (9.46%). The national population-weighted average combined rate is 7.53%.

Finding your exact local rate

The most reliable source is a recent receipt from a store near you, or your state revenue department’s rate lookup, which can find the combined rate for a street address. Enter that full rate in the “exact combined rate” box and the state/local estimate is replaced.

Limitations & Accuracy Notes

  • Local rates are not built in because they vary by address — sometimes across a single street. Enter yours for an exact answer.
  • Many states exempt or reduce tax on groceries, prescription drugs and clothing, and some tax services; the calculator applies one rate to the whole amount.
  • Vehicle purchases often carry separate excise or registration taxes that are not sales tax.
  • This is an estimate for shoppers and small sellers, not tax advice; businesses should confirm rates and taxability with their state.

Frequently Asked Questions

How do I calculate sales tax?
Multiply the price by the tax rate as a decimal. At 7.25%, a $100 item has $100 × 0.0725 = $7.25 in tax, for a total of $107.25. The rate that applies is your state rate plus any county, city and district rates for the place where you take delivery.
How do I remove sales tax from a total?
Divide the total by 1 plus the rate. $107.25 ÷ 1.0725 = $100.00 before tax. Subtracting 7.25% of the total instead gives $99.47 — a common mistake that undercounts the pre-tax price, because the tax was charged on the smaller number.
Which states have no sales tax?
Alaska, Delaware, Montana, New Hampshire and Oregon have no statewide sales tax. Alaska allows local sales taxes, and some Montana resort areas levy their own; Delaware and Oregon have none at any level.
Why is my receipt’s tax rate higher than the state rate?
Because most places add local sales taxes on top of the state rate. Counties, cities and special districts can each add their own, so the combined rate can differ between neighboring towns. Enter your local rate, or the exact combined rate from a receipt, for a precise answer.
Which state has the highest sales tax?
California has the highest statewide rate at 7.25%. Combined with local taxes, Louisiana has the highest average combined rate as of 2026 (about 10.13%), followed by Tennessee, Washington, Arkansas and Alabama, according to the Tax Foundation.
Is sales tax charged on shipping?
It depends on the state. Some tax shipping charges when the item is taxable, some exempt separately stated delivery charges, and the rules can differ for handling fees. Check your state revenue department’s guidance if shipping is a large part of the total.
Are these rates current?
The state rates are the 2026 statewide base rates published by the Tax Foundation. The District of Columbia is the one scheduled change: 6.5% until September 30, 2026 and 7% from October 1, 2026, and the calculator switches automatically by date.
