Frequently asked questions
How is property tax calculated in Maricopa County?
The Maricopa County Assessor's Office sets both a full cash value and a capped limited property value each year, and local taxing jurisdictions generally apply their rates to the lower, capped figure. Arizona's statewide growth limit keeps that capped value from rising as fast as market prices in a hot year.
How do I appeal my Maricopa County assessment?
The Maricopa County Assessor's Office takes appeals directly, and the county Board of Equalization is the next stop if that outcome doesn't satisfy you. Both stages run on the deadline printed on your valuation notice.
Does Maricopa County offer a homestead exemption?
Arizona doesn't have a traditional homestead exemption for property tax the way some states do, though other exemptions exist for qualifying veterans, widows, widowers, and disabled residents that reduce assessed value.
Why is my Maricopa County home's assessed value lower than its market value?
Arizona's limited property value system caps how much your assessed value can grow each year, so in a rising market it often lags behind what the home could actually sell for. That gap tends to close gradually or reset when the cap catches up over several years.
