Property tax rates in Hawaii vary depending on the county and assessed value of the property. Property taxes are assessed annually based on the value of the property as of January 1st of the tax year, and the tax rate is then applied to the assessed value. Hawaii tax rates are as follows: Hawaii County from 0.61% to 1.36%; Kauai County from 0.25% to 1.08%; Maui County from 0.19% to 1.46%; and Honolulu County from 0.35% to 1.39%. If the property is your principal residence, there is an exemption that provides a tax credit to be applied to the assessed value before the property tax rate is calculated. Read more.
