How a sales tax rate is built
The rate at the register is rarely one number. It is the sum of every jurisdiction that taxes the sale at that address, which is why two stores a few miles apart can charge different amounts.
A single ZIP code can cross city or county lines, so one ZIP can carry more than one combined rate.
State rate
Set by the state legislature and applied statewide. Alaska, Delaware, Montana, New Hampshire and Oregon have no statewide sales tax, although Alaska lets local governments levy their own.
County rate
Added by the county where the sale takes place, in states that allow county sales taxes.
City rate
Added by the city or town. Buyers outside city limits often pay less even with the same mailing address.
Special districts
Transit, stadium, library or improvement districts that add their own small rate inside set boundaries.
Combined rate
The total of all four layers. This is the rate the calculator applies to your purchase price.
