Sales Tax Calculator
The Sales Tax Calculator can compute any one of the following, given inputs for the remaining two: before-tax price, sale tax rate, and final, or after-tax price. You can optionally select a US state to pre-fill the average combined state and local sales tax rate.

What Changed in 2026
No state changed its base sales tax rate in 2026, but several made changes to what gets taxed and how local rates shifted.
- Illinois eliminated its 1% statewide grocery tax, though counties and cities can still impose their own local grocery taxes of up to 1%.
- Arkansas repealed state sales tax on groceries entirely. Local taxes on groceries still apply.
- California was among the states with a notable combined-rate increase from local changes, bringing its population-weighted average to 9.03%.
- Wyoming was the only state whose average combined rate decreased between January and July 2026, reaching 5.39%.
How Combined Rates Work
The rates shown above are averages. Your actual rate depends on your exact city, county, and any special taxing districts. A state like Louisiana has a 5.00% state rate, but local taxes push the average combined rate to 10.13%, the highest in the country. Meanwhile, five states collect no statewide sales tax: Alaska, Delaware, Montana, New Hampshire, and Oregon. Alaska is a special case: it has no state-level tax, but many of its cities and boroughs collect local sales taxes, averaging 1.82% statewide.

Sales tax calculators by state
Every state sets its own rates, and local taxes change the total you pay at the register. Pick your state for a calculator preset with its 2026 rates, purchase tables, and rate details.
Methodology and limitations
To add tax, the calculator multiplies the before-tax price by the rate entered and adds that tax to the price. To reverse a tax-inclusive total, it divides the total by one plus the rate. State presets use each state's statutory rate plus the population-weighted average local rate where applicable.
The comparison table comes from the Tax Foundation's midyear 2026 state and local sales-tax dataset, which reports rates as of July 1, 2026. Local rates are averages, so enter the rate for the exact city, county, or special district when you know it.
