Hawaii Adds a Climate Fee to Rental Taxes in 2026
Hawaii's statewide transient accommodations tax (TAT) rises to 11% on January 1, 2026, up from 10.25%, after the legislature added a 0.75-point climate impact fee to fund coastal and wildfire resilience work. Layer the general excise tax of roughly 4% to 4.5% and, in Honolulu, an additional 3% county TAT on top of that, and a booking on Oahu can carry a combined tax load north of 18% before a host has paid anything toward a permit.
That tax change applies statewide and is the easy part. What actually determines whether a listing can legally take a booking in 2026 depends entirely on which island, and often which zoning district, the property sits in. Hawaii regulates short-term rentals at the county level, not the state level, and the four counties have moved in different directions for years. That gap is widening, not closing.
What each county now requires
Honolulu still enforces Ordinance 22-7, which confines new short-term rentals to resort-zoned parcels on Oahu and pushes everything else to a 30-day minimum stay, with a nonconforming-use registry for a shrinking pool of legacy units grandfathered in before the rule took effect. Maui County is further along a phase-out that its council approved after the 2023 Lahaina fires, aimed at converting roughly 7,000 apartment-zoned short-term rental units back to long-term housing stock, with compliance deadlines staggered by district through 2028 rather than a single cutoff date. Kauai caps non-conforming-use certificates and has not issued new ones in most residential zones for years, while Hawaii County (the Big Island) runs a comparatively simpler registration system built around its transient accommodations permit, though even there specific districts carry their own restrictions.
None of this is optional paperwork. Hosts operating without the correct county permit or registry number face fines that in Honolulu's case can run into five figures per violation, and platforms including Airbnb and Vrbo have cooperated with counties on delisting unregistered properties in the past when asked to under local ordinances.
Where operators are likely to get caught out
The biggest risk for 2026 is treating Hawaii as one market. A management company running listings across Oahu, Maui and Kauai is really running three separate compliance regimes with different tax add-ons, different renewal cycles and different zoning maps, and a rule change on one island says nothing about the others. Anyone who bought or listed a Maui property recently should confirm which phase-out deadline applies to its specific district before assuming an existing registration carries them through to 2028.
For hosts trying to keep permit renewals, tax filings and county-specific documentation straight across multiple islands, a rundown of the current island-by-island requirements is laid out in a property management guide from Lodgify, which is a reasonable starting point before checking the primary county ordinance directly. The state tax change takes effect regardless of island; the permit rules do not, and that distinction is the one worth building into any 2026 compliance checklist.
