Why the rate here is not the whole story
Arizona has no sales tax in the strict sense. It levies a transaction privilege tax, or TPT, on the seller for the privilege of doing business, and the seller normally passes it on at the register, so it works like a sales tax for a buyer. The state charges 5.6 percent on retail, La Paz County adds 1 percent, and cities add their own on top, so a single rate for the whole county does not exist. The floor of 6.6 percent is unincorporated county, outside any city. The ceiling of 9.1 percent is at Quartzsite, where the city adds 2.5 percent. Sales on tribal land report the same state and county rate under the department's reservation region codes, but a tribe may levy its own tax that the department does not collect or publish, so the total there can be higher than the ceiling shown. The department publishes the state and county component in one table and the city component in another and never publishes a combined figure for a location, so the ceiling here is those two published figures added rather than a rate read off the page. Confirm an address on the department's own lookup before charging it.
