California has the highest base state sales tax at 7.25%. However, combined state and local rates can be much higher. Louisiana (4.45% + high local rates), Tennessee (7% + local), and Arkansas (6.5% + local) often have among the highest combined rates when including city and county taxes.
In most US states, sales tax applies to tangible goods but not services. However, about 20 states do tax some services. Hawaii taxes nearly all services. New Mexico taxes most services. Texas taxes some services. The rules vary significantly by state and service type.
To add sales tax to a price: multiply the price by (1 + tax rate). For example, $50 item with 8% tax = $50 × 1.08 = $54. Our sales tax calculator shows you the tax amount and final price separately so you can see exactly how much tax is added to any purchase amount.
