Sales Tax Calculator
State and local tax on a sale, including shipping.
Rates change with budgets and local ballot measures, and the rate that applies depends on the delivery address and product category. Treat these as planning figures, not as a filing.

Local district taxes usually exceed the state rate's variation, so the delivery address matters more than the state does. Rates are set per address, not per city.
How the Sales Tax Calculator works
US sales tax is set per address, not per state. The state rate is the floor; county, city and special district taxes stack on top and account for most of the variation between two customers a few miles apart. Whether shipping is taxable is a separate question with a different answer in about half the country.
Not financial advice. Marketplace fees change, and they vary by country, plan and seller status. Every rate here is an editable default, not a quoted price — check the platform's current fee schedule before you price a product against it. This is not tax or business advice.
Frequently asked questions
How do I calculate sales tax?
Multiply the taxable amount by the combined rate — state plus county plus city plus any special districts. The combined rate for a delivery address is what matters, not the state rate.
Is shipping taxable?
It depends on the state. Roughly half tax delivery charges when the goods themselves are taxable, and half do not. Some exempt shipping only when it is separately stated on the invoice, which is a common trap for sellers who bundle it into the item price.
Which rate applies — mine or the customer's?
Almost always the customer's, because most states are destination-sourced. A handful, including Texas, source intrastate sales to the seller's location. Interstate sales are destination-sourced everywhere.
Do I charge tax on every sale?
Only in states where you have nexus, and only on taxable products. Groceries, clothing and prescription items are exempt or reduced in many states, and resale certificates exempt wholesale sales entirely.
