Hawaii calls its hotel tax the Transient Accommodations Tax, or TAT. The state sets a base rate that applies statewide, and each of Hawaii's four counties layers its own additional county TAT on top, a two-tier structure rather than one blended state rate.
The state TAT rate rose from 10.25% to 11% effective January 1, 2026 under Act 96, a dedicated climate-impact fee, commonly called the "Green Fee," signed into law after the 2023 Maui wildfires. The same act also applies TAT to cruise ships for the first time.
The tax applies to lodging furnished to a transient for less than 180 consecutive days per letting, a materially longer threshold than the 30-day rule common in most other states.
Because the state and county portions combine identically across all four counties, the headline TAT rate is the same everywhere in Hawaii, but a separate tax, the General Excise Tax, adds a further county-specific layer on top. Here's where things stand as of 2026.
| County | Combined TAT | Notes |
|---|---|---|
| City and County of Honolulu (Oahu) | 14% | 11% state plus 3% Oahu county TAT (OTAT), effective since December 2021 |
| County of Maui | 14% | 11% state plus 3% Maui county TAT, in effect since November 2021 |
| County of Hawaii (Big Island) | 14% | 11% state plus 3% Hawaii County TAT (HCTAT) |
| County of Kauai | 14% | 11% state plus 3% Kauai county TAT (KTAT), adopted after the county lost roughly $15 million a year in state revenue-sharing |
On top of TAT, every county also charges a General Excise Tax (GET) surcharge that lands on the hotel folio even though it's legally a separate tax on the business's gross receipts, not TAT itself. All four counties currently charge a 0.5% GET surcharge, bringing combined GET to 4.5%, though the maximum rate hotels are permitted to visibly pass on to guests is 4.712%, not a flat 4.5%.
Unlike California's stacked Tourism Business Improvement Districts, Hawaii doesn't layer a separate hotel-specific marketing assessment on top of TAT. Visitor marketing is instead funded by a fixed dollar amount taken directly off the top of state TAT collections.
The guest pays TAT, and the property remits it, but the filing cadence genuinely varies by taxpayer size. The default is monthly, due on or before the 20th of the following month. A property may qualify for quarterly filing if its total annual TAT liability won't exceed $4,000, or semiannual filing if it won't exceed $2,000.
A state return filed with the Department of Taxation is treated as filed with each county too, but payment still has to be remitted separately to the county. Electronic payment mandates also differ: Oahu requires electronic filing above $50,000 in annual TAT liability, while Hawaii County sets that threshold at $100,000.
Hawaii's exemption threshold is 180 consecutive days per letting, not the 30-day rule common elsewhere. A letting under 180 days is presumed transient and taxable; a letting of 180 days or more carries no automatic presumption either way, and the burden falls on the operator to prove the stay wasn't transient.
Every registered operator must also post a "local contact," someone physically present on the same island as the unit. Missing this isn't a minor paperwork gap: fines are steeply tiered, from $500 for a first citation up to $5,000 for a third or later violation, per unit.
None of the above is about software. It's about a Hawaii property tracking a 180-day exemption window instead of the more common 30 days, keeping the local-contact posting current, and remitting state and county TAT to the right places on the right cadence. Where a PMS actually helps is in configuring tax codes and exemption logic correctly per island, and pulling revenue reports by date range for whichever filing frequency a property qualifies for. roommaster lets properties configure tax codes per rate, so a statewide rate change like the 2026 Green Fee increase is a configuration update once, not a manual recalculation on every folio.
Hawaii has an 11% state Transient Accommodations Tax that applies everywhere, plus a 3% county TAT layered on top in all four counties, for a combined 14% statewide.
Hawaii's hotel tax is the Transient Accommodations Tax, or TAT, an 11% state charge plus a 3% county charge that's identical in structure across Oahu, Maui, Hawaii Island, and Kauai.
Lodging tax is the same charge as Hawaii's Transient Accommodations Tax, just a different common name for it. It combines a state rate and a county rate rather than one single figure.
It's the 0.75 percentage point increase to the state TAT rate, from 10.25% to 11%, effective January 1, 2026, dedicated to climate resilience, wildfire prevention, and coastal protection.
180 consecutive days. A stay under that length is presumed taxable; a stay of 180 days or more shifts the burden to the operator to show it wasn't a transient stay.
Not yet. A state bill addressing fee disclosure is pending in the legislature, and a similar federal bill has passed the U.S. House but hadn't passed the Senate as of this writing.
The property collects TAT from the guest and remits it, monthly by default, though quarterly or semiannual filing is available for properties under specific annual liability thresholds.
