Arizona property tax deadlines
20 sourced dates. 15 of 15 Arizona counties have at least one.
Arizona sets its dates in state law (Title 42 of the Arizona Revised Statutes), and each county treasurer sends the bills. You pay in two halves, and each one turns late at 5 p.m. on its last day, not at midnight. Pay the whole year by December 31 and you owe no interest on the first half. Late taxes cost 16% a year.
