What Maricopa County property tax looks like
Among the 30 counties covered here, Maricopa County has the 30th highest effective rate and the 29th highest median bill. Every $100,000 of value carries about $474 of tax a year at this rate.
On a $400,000 purchase that comes to roughly $1,896 a year, or $158 a month. Priced at the Arizona average rate instead, the same home would cost $15 a month more in tax.
Primary property taxes are computed on the Limited Property Value, which can rise by at most 5% a year, rather than on the market-based Full Cash Value, so a long-held home is often taxed on well under its market value.
Parcel-level values and tax history are published by the Maricopa County Assessor.
