US sales tax — quick answers
Which US states have no sales tax?+
Five states have no statewide sales tax: Alaska, Delaware, Montana, New Hampshire, and Oregon. Alaska allows local jurisdictions to levy their own sales taxes, so some Alaskan cities do charge sales tax.
How is sales tax calculated?+
Multiply the pre-tax price by the combined tax rate (state + local) expressed as a decimal. Example: an $80 item at 8.25% tax = $80 × 0.0825 = $6.60 tax, total $86.60.
Do online purchases have sales tax?+
Often yes. Many states require online retailers to collect applicable taxes depending on their rules and thresholds. Confirm with your state’s tax authority if you’re self-assessing use tax.
What is use tax vs sales tax?+
Use tax can apply when you buy a taxable item without paying sales tax (for example, an out-of-state seller that didn’t collect tax). Rates are typically similar to your local combined sales tax, but rules vary by state.
Are groceries taxed in the US?+
It varies by state and item type. Some states exempt groceries, some tax them at reduced rates, and prepared food is often taxable.
