Hawaii has no state property tax, every county runs its own system, and every county reassesses its full inventory of parcels annually at market value, not every two years as is sometimes claimed. Inheriting a home doesn't trigger a special reassessment on top of that cycle. What it does trigger is a fresh homeowner exemption application, on a September 30 deadline that has nothing to do with the appeal deadline, which itself is a different date depending on which county the home is in.
Honolulu, Maui, Hawaii, and Kauai counties each independently value every parcel to 100% of fee-simple market value on a yearly cycle, using sales data through the prior June 30, with assessment notices mailed on each county's own calendar (Maui County, for example, mails by March 15, with appeals due April 9). Ownership changes don't add a separate reassessment event, the parcel is already being revalued every year regardless of who owns it.

Honolulu's home exemption, the most common Hawaii example, currently removes $120,000 of assessed value for owner-occupants under 65 and $160,000 for those 65 and older, requiring at least 270 days of occupancy in the year. Honolulu's own guidance is direct: buying, or inheriting, a home with an existing exemption does not transfer it to you. Each new owner has to file an individual claim.
The deadline to file that new claim is September 30 of the year before the tax year you want it to apply to. That is a completely different date from the property assessment appeal deadline discussed below, don't conflate an heir's exemption filing window with the window to dispute the assessed value.
Hawaii has no tax on the person who inherits. It does have a state estate tax on the estate itself, under HRS Chapter 236E, filed on Form M-6, with a current filing threshold of $5,490,000. Below that, no Hawaii estate tax return is even required. Given Hawaii's home prices, this threshold is high enough that it's rarely relevant to a straightforward home inheritance, but confirm the current-year figure on the Department of Taxation's Form M-6 instructions if the estate is unusually large.

Every county uses the same two-tier structure, a county Board of Review first, then the state Tax Appeal Court within 30 days of the Board's decision, but the Board of Review filing deadline genuinely differs by island, and this is worth stating explicitly rather than leaving as "varies":
If you're appealing an inherited property, confirm the deadline for the specific island it's on rather than assuming one statewide date applies.
No. Every Hawaii county reassesses its parcels annually at market value regardless of who owns them, so an inherited home was already on that cycle and stays on it. There is no separate transfer-triggered event.
No. Honolulu's Real Property Assessment Division states directly that an existing exemption does not transfer to a new owner. You have to file your own claim by September 30 of the year before the tax year you want it applied to.
No. Honolulu's Board of Review deadline is January 15. Hawaii County and Maui County both use April 9. Kauai County uses December 31, or 30 days from the assessment notice. Confirm the deadline for the specific county your inherited property is in.
No, Hawaii has no tax on the person receiving an inheritance. A separate state estate tax applies to the estate itself, but only above a $5,490,000 filing threshold, well beyond what a typical inherited home triggers.
30 days from the date the Board of Review files its decision, under Hawaii Revised Statutes § 232-17. This step is the same statewide even though the initial Board of Review filing deadline differs by county.
