Arizona Property Tax Calculator

How Arizona property tax works

Arizona taxes a home’s Limited Property Value (LPV), not its market price. LPV can rise at most 5% a year unless the property changes. Homes are assessed at 10% of LPV. Each taxing jurisdiction then sets a rate per $100 of assessed value, and your tax is the assessed value times the combined rate.

Primary taxes fund county, city and school operations. Secondary taxes fund bonds, special districts and voter-approved overrides. For an owner-occupied home, the state pays part of the school tax when primary taxes would otherwise exceed 1%, and a homeowner rebate is applied automatically. The county estimates come from what owners actually paid, so they already include these credits. The Arizona method does not, so its result can run higher than your bill.

Here is an illustrative example, not a real tax area. A home with an LPV of $300,000 has an assessed value of $30,000. At a combined rate of $8.50 per $100, the annual tax is $2,550, or $212.50 a month. Your Notice of Value and tax bill give your own LPV and rate; enter them in the Arizona method above. Rules are from the Arizona Department of Revenue, “Arizona Property Taxation” (February 2024).

Why Arizona’s property tax rate looks low

The effective rate in the table is tax divided by market value. Arizona taxes LPV, and LPV can rise at most 5% a year. When market prices rise faster than that, LPV falls behind the market. The tax is then a smaller share of what the home would sell for, so the effective rate drops.

This is why a county’s effective rate is a rough guide for a home you are about to buy, and why your own bill can differ. See the methodology for how this site treats property tax.

When Arizona property taxes are due

Taxes are paid in two halves. The first half is due October 1 and is delinquent after November 1. The second half is due March 1 and is delinquent after May 1. You can also pay the full year by December 31 without interest on the first half. A bill of $100 or less is due in full by November 1.

If your lender collects property tax in escrow, it pays these bills for you. Funding escrow is one of several costs at closing; see closing costs explained for the rest.
