Hawaii Notes
Important state-specific details
Hawaii has NO state property tax - all property taxes are county-level only.
Hawaii property taxes are among the LOWEST in the nation by effective rate - Hawaii's high property values combined with generous homeowner exemptions and classification systems result in relatively modest bills for most owner-occupants.
HOME EXEMPTION: Each county offers a homeowner exemption for primary residences that significantly reduces the assessed value subject to tax - apply at your county Real Property Tax Division; Honolulu: $100,000 exemption for most homeowners; additional exemptions for seniors 65+.
TAX MAP KEY (TMK): Hawaii uses a TMK (Tax Map Key) system to identify parcels - this is the parcel number on your tax bill.
Hawaii uses a property classification system (residential, hotel/resort, commercial, agricultural, etc.) with different tax rates for each class.
No homestead cap on assessment increases in Hawaii - assessments can increase significantly year-to-year in rising markets.
