Sales tax in the US is notoriously complicated — rates vary by state, county, and city, and what's taxable varies too. A pair of shoes might be taxable in one state and exempt in the next. Groceries, medicine, and services each have different rules depending on where you are.
This free sales tax calculator instantly adds or removes sales tax for any US state and major city, updated for 2026 rates. Enter any price — pre-tax or post-tax — and get the complete breakdown.

The highest combined rates: Louisiana (~9.55% average combined), Tennessee (~9.55%), Arkansas (~9.46%), Washington (~9.38%), Alabama (~9.24%).
For the complete state-by-state table, the Tax Foundation publishes current rates annually.

New York State's base sales tax rate is 4%. Counties add 3%–5%, and New York City adds an additional 4.5% city tax + 0.375% Metropolitan Commuter Transportation District (MCTD) surcharge. Combined NYC sales tax: 8.875% — one of the highest in the country for a major city.

To add sales tax: Final price = Original price × (1 + tax rate). A $50 item in a location with 8% sales tax: $50 × 1.08 = $54. To reverse-calculate (find pre-tax price from a total): Pre-tax price = Total ÷ (1 + tax rate). $54 total ÷ 1.08 = $50 pre-tax.
Our calculator handles both directions — add tax to a pre-tax price, or remove tax from a post-tax total — for any state or custom rate you enter.
Sales tax rules on exemptions vary significantly by state but common patterns include: Groceries (unprepared food): exempt in most states including Texas, Florida, California, New York | Prescription drugs: exempt in all 50 states | Over-the-counter medicine: exempt in most states | Clothing: exempt in New York (under $110/item), Pennsylvania, New Jersey, Minnesota; taxable in most others | Services: most states tax goods but exempt most services; Hawaii, South Dakota, New Mexico are major exceptions that tax many services | Digital products (streaming, software, e-books): increasingly taxable in more states as laws adapt to the digital economy.

Five states have no statewide sales tax: Alaska, Delaware, Montana, New Hampshire, and Oregon. Note that Alaska, while it has no state sales tax, allows local municipalities to charge sales tax — so some Alaskan cities do have local sales tax. Oregon and New Hampshire are the cleanest no-sales-tax states with no local sales taxes either.
Sales tax is collected by the seller at the point of sale. Use tax is the buyer's obligation to self-report and pay tax on taxable purchases where sales tax was not collected — most commonly out-of-state purchases or online purchases from sellers who didn't collect your state's tax. Use tax rates are identical to sales tax rates.
Most states include a use tax line on their income tax return. The legal obligation exists even if enforcement is limited for small individual purchases.
Sales tax rates and rules change frequently. This calculator provides estimates based on current known rates and should not be used for official business tax filings or compliance purposes. For official state tax rates and exemption rules, always consult your state's department of revenue or a tax professional.

Multiply the price by the combined sales tax rate as a decimal, then add it to the price. For example, $100 at a 7.25% rate is 100 × 0.0725 = $7.25 tax, for a $107.25 total.
The US has no national sales tax. Each state sets its own rate, and counties and cities can add local taxes on top, so the combined rate differs from place to place.
Divide the gross price by (1 + rate). For a $107.25 total at 7.25%, the pre-tax price is 107.25 ÷ 1.0725 = $100, so the tax was $7.25.
Five states have no statewide sales tax: Alaska, Delaware, Montana, New Hampshire and Oregon (though some Alaskan localities levy their own). Enter 0% for purchases there.
