Sales tax breakdown
The combined rate behind the number
US sales tax is a state rate plus any local county or city rate, applied to the price. When a price already includes tax, the tax is backed out of the gross. When it excludes tax, the tax is added on top.
State plus local
Most purchases are taxed at a state rate plus a local rate that varies by county and city. The combined rate at a given address is what actually applies, so the local rate matters as much as the state one.
Approximate quick-pick
The state picker fills in an approximate base rate as a starting point. A handful of states have no statewide sales tax. Always confirm the exact rate for the destination address.
Inclusive or exclusive
When a shelf price already includes tax, the pre-tax amount is the price divided by one plus the combined rate. When it excludes tax, the tax is added on. This tool handles both.
State base rates are approximate and change over time. Combined local rates vary by jurisdiction. Verify the applicable rate against the sources below and the state Department of Revenue.
This is an example estimate based on the rates entered. State base rates shown are approximate and local rates vary widely by jurisdiction. It is not tax advice. Confirm the combined rate for the specific address with the state Department of Revenue.
Let sales tax follow the invoice, not a lookup table
Rivane applies the right rate to every US invoice and keeps the tax collected ready to remit, so a filing figure is a report, not a spreadsheet.
