What property tax rate does this Arizona estimator use?

It uses Arizona's 0.63% effective property tax rate, the average ratio of tax actually paid to home value across the state. On a $300,000 home that is about $1,890 per year.

Is the 0.63% rate the same in every county?

No. 0.63% is the statewide effective average. Your local rate depends on county, city, school district and special levies, so your real bill can be higher or lower. Check your assessor's office for the exact millage.

How is the annual tax calculated?

Annual tax = (assessed value minus any exemption) multiplied by 0.0063. For a $300,000 Arizona home with no exemption that is about $1,890 a year, or roughly $158 per month.

Does a homestead exemption lower my bill?

Yes. A homestead exemption reduces the taxable value before the rate is applied. A $25,000 exemption on a $300,000 Arizona home drops taxable value to $275,000, cutting the estimated tax to about $1,733 per year.

The Arizona Property Tax Estimator (2026) estimates your annual and monthly Arizona property tax using the state’s 0.63% effective tax rate — the average ratio of property tax paid to home value across Arizona. Enter your assessed or market value to see the yearly bill.

How it works

Arizona property tax is based on your property’s taxable value and the local millage, but on average homeowners pay about 0.63% of their home’s value each year. This estimator applies that effective rate:

taxable value = assessed value - exemption
annual tax = taxable value x 0.0063
monthly tax = annual tax / 12

You can enter a homestead or other exemption, which is subtracted from the value before the 0.63% rate is applied.

Example

On a $300,000 Arizona home with no exemption, the annual property tax is $300,000 x 0.0063 = about $1,890, or roughly $158 per month. Adding a $25,000 homestead exemption drops the taxable value to $275,000 and the annual tax to about $1,733.

Notes

This is an estimate for planning only, not tax or legal advice. The 0.63% figure is Arizona’s statewide effective average; your actual rate varies by county, city, school district and special assessments, and exemptions differ by jurisdiction. Confirm your exact assessed value, exemptions and millage with the Arizona county assessor or department of revenue.
