Add local county + city taxes if you know your total combined rate.
Sales tax in the United States is imposed at the state level, with 45 states + the District of Columbia collecting a statewide rate. Five states — Alaska, Delaware, Montana, New Hampshire, and Oregon — have no statewide sales tax. On top of the state rate, most counties and cities add their own local sales tax, so the total combined rate you charge a customer can differ from block to block.
This calculator shows the state-level 2026 rate for each of the 50 US states as published by their departments of revenue. Use the Custom rate override field if you need to add county + city taxes to arrive at the exact combined rate for a specific ZIP code.
Most US businesses must collect sales tax on taxable goods and certain services if they have nexus in a state — typically because they have a physical location, employees, inventory, or (since 2018 Wayfair) meet economic-nexus thresholds like $100k in sales or 200 transactions in that state.
Once you have the tax amount, plug it into our free invoice generator — pick the state, and the correct tax label (Sales Tax, VAT, GST) is auto-filled to match. If you need to itemize state + county + city taxes separately, add them as separate line items with a discount of 0%.
A California contractor bills a client $2,500 for services. California’s statewide sales tax is 7.25% — the tax comes to $181.25 and the invoice total is $2,681.25. If the job is in Los Angeles (combined rate ~9.5%), the tax would be $237.50 for a total of $2,737.50 — which is why the custom-rate override matters for local jobs.
