Arizona transaction privilege tax
Phoenix rate breakdown
Phoenix uses Arizona's transaction privilege tax system rather than a conventional retail sales tax. The charge may still appear in the final amount paid, so the same reverse calculation works when you enter the rate shown on the receipt.
| Rate component | Reference rate | What it represents |
|---|---|---|
| Arizona state portion | 5.6% | State-level portion used by this city record |
| Local combined portion | 3% | City, county, transit, or district taxes combined |
| Phoenix reference total | 8.6% | Maricopa County |
City boundaries and special districts can change the exact rate. Use the transaction rate or verify the address with Arizona Department of Revenue.
