How Sales Tax Works in the US
In the United States, sales tax is a consumption tax imposed on the sale of goods and services. The tax rate varies by location because it is a combination of:
- State Sales Tax: A base rate set by each state. As of 2026, rates range from 0% to 7.25% (California).
- County Sales Tax: Many counties add their own tax on top of the state rate.
- City / Municipal Sales Tax: Cities can also levy additional taxes.
- Special District Tax: Special taxing districts (e.g., transit, tourism) may add more.
The combined sales tax rate is the sum of all applicable rates at the location where the purchase occurs.
