About the US Sales Tax Calculator by State
Pick a state and its statewide sales tax rate fills in from that state’s own revenue department or statutes, add the local rate for the place of sale, and see the tax and total — for one price or a list of items, with taxable and non-taxable lines. Reverse mode takes the tax out of a total that already includes it.
For California, Georgia, New York, North Carolina and Ohio you can also pick a city or county from the state’s own rate table; Pennsylvania’s Allegheny County and Philadelphia taxes and Virginia’s regional rates are built in. Local rates change by address and over time, so every state links to its revenue department, and to its address lookup where it has one.
How to use it
- Choose the state. Its statewide rate appears with a link to the page it comes from; states not loaded here ask you to type the combined rate.
- Add the local rate: pick your city or county where the state publishes a table, or type the county, city and district rates together.
- Choose Add tax and enter the price — or add more lines with quantities and untick lines that are not taxed.
- For a receipt total that already includes tax, choose Remove tax and enter the total.
- Pick per-invoice or per-line rounding to match your register, then copy the result or download the lines as CSV.
Examples
$19.99 at 10.25% (state 7.25% + district taxes)
Tax $2.05 · total $22.04
$108.25 paid at 8.25% (6.25% state + 2% local)
Price $100.00 · sales tax $8.25 (state $6.25, local $2.00)
8.875% (4% state + 4.5% city + 0.375% MCTD)
Per-invoice rounding: tax $0.26 · per-line rounding: tax $0.27
Rounding each line can add a cent per line; states and registers differ in which they use.
State rates and where they come from
Each preset is the statewide rate stated on that state’s revenue department page (for Arizona, Kansas and Wyoming, in the state’s statutes, with the department linked beside it), for example 7.25% in California, 6.25% in Texas, 6% in Florida, 4% in New York, 6% in Pennsylvania, 5.75% in Ohio, 6.25% in Massachusetts and 7% in Tennessee. The calculator shows the source link next to the state you pick.
Montana (DOR) and Oregon (DOR) have no general sales tax. Alaska has no state sales tax (IRS Schedule A instructions), but many of its boroughs and cities charge their own, so you type the local rate. A few states are not loaded yet; for them you type the rate from the department’s site, which is linked.
Local rates: county, city and district taxes
Most states let counties, cities, transit authorities or special districts add their own sales tax, so the rate depends on where the sale takes place. In Texas the local taxes can add up to 2%, for a maximum combined 8.25%; Ohio counties and transit authorities can add up to 3% (8.75% in all); in New York an extra 0.375% applies in the Metropolitan Commuter Transportation District; California district taxes add 0.10% to 2.00% in many areas.
The city and county lists for California, Georgia, New York, North Carolina and Ohio come from those states’ own rate tables and are offered only while the table they come from is current. For an exact rate at an address, use the state’s lookup, linked in the calculator.
Adding tax and backing it out
- Add tax: tax = taxable amount × (state rate + local rate). On $100 at 8.25%, tax is $8.25 and the total $108.25.
- Remove tax: price = total ÷ (1 + rate). A $108.25 total at 8.25% is $100.00 plus $8.25 of tax. Do not subtract 8.25% of the total: that gives $8.93, which is too much.
- Rounding: tax is rounded to the nearest cent, with half a cent rounded up. Rounding once on the whole invoice and rounding each line can differ by a cent per line; check which your state or your point-of-sale system uses.
Limitations
- Only general sales tax is calculated: special rates for groceries, prepared food, vehicles, lodging, fuel or alcohol are not applied — untick or adjust those lines yourself.
- Local rates vary by address, not only by city: unincorporated areas, transit districts and special districts can differ inside one city. Use the state’s address lookup for an exact rate.
- Some states are not loaded; for them the combined rate must be typed in.
- Which goods and services are taxable differs by state; this calculator does not decide that for you.

Frequently asked questions
How do I calculate sales tax on a price?
Multiply the price by the combined rate (state plus local) as a decimal: $50 at 7.5% is $50 × 0.075 = $3.75, for a total of $53.75.
How do I find the price before tax from a receipt total?
Divide the total by 1 plus the rate: $53.75 ÷ 1.075 = $50.00. The tax is the difference, $3.75. Choose Remove tax to do this for any total.
Which states have no statewide sales tax?
Montana and Oregon have no general sales tax, as their revenue departments state, and Alaska has no state sales tax, although many Alaska boroughs and cities charge a local one. Delaware and New Hampshire are not loaded in this calculator yet: pick one to see the link to its revenue department and type the rate that applies to your sale.
Why is my local rate different from the city’s published rate?
Special districts, transit authorities and unincorporated areas can change the rate at a particular address. Use the state’s address lookup (linked next to the state) for the exact rate.
Should tax be rounded per line or on the whole invoice?
Some sellers round once on the taxable total of the invoice, others round each line. The difference is at most half a cent per line. Choose the option that matches how you invoice, and follow your state’s rule where it sets one.
