About Sales Tax

Sales tax is a consumption tax imposed by state and local governments on the sale of goods and services. In the United States, there is no federal sales tax — each state sets its own rate, and many cities and counties add additional local taxes.

Five states have no statewide sales tax: Alaska, Delaware, Montana, New Hampshire, and Oregon. However, Alaska allows local governments to impose sales taxes.

Disclaimer: Rates shown are approximate combined averages. Actual rates vary by city, county, and product type. Always verify with your local tax authority.
