Hawaii property tax deadlines
20 sourced dates. 4 of 5 Hawaii counties have at least one.
Hawaii has no state property tax. Each county sets its own dates in its own code, so appeal and exemption deadlines differ from island to island. The tax year runs July 1 to June 30, and in the counties covered here you pay in two parts, due August 20 and February 20. Kalawao County isn't listed because no official page says who taxes it.
Own in two states: California and Hawaii
