How It Works
Sales tax in the US is set at both state and local levels. State rates are fixed, but local rates vary by city and county. We use average combined rates for each state, but your actual rate may differ based on your specific location.
Frequently Asked Questions
Which states have no sales tax?
Five states have no state sales tax: Alaska, Delaware, Montana, New Hampshire, and Oregon. However, Alaska allows local jurisdictions to charge sales tax.
Why do rates vary within a state?
Cities and counties can add their own sales tax on top of the state rate. This funds local services like transit, schools, and infrastructure. Urban areas often have higher combined rates than rural areas.
Are all purchases taxed equally?
No. Many states exempt groceries, prescription drugs, and clothing from sales tax. Some items have special tax rates. This calculator uses the standard general sales tax rate.
