How Hawaiʻi STR tax works
Every Hawaiʻi STR pays three stacked taxes on the same gross rental receipts:
- GET — General Excise Tax. State, 4%, plus county surcharge (0.25% Big Island, 0.5% Oʻahu + Kauaʻi, none Maui). Filed via Form G-45 monthly/quarterly + G-49 annually. HRS §237.
- TAT — Transient Accommodations Tax. State, 10.25% flat. Filed via Form TA-1 monthly/quarterly + TA-2 annually. HRS §237D.
- County TAT — 3% to the county. Goes by different names depending on county: MCTAT (Maui), OTAT (Oʻahu), HCTAT (Hawaiʻi County), KCTAT (Kauaʻi). Filed separately to the county.
The math: tax = rate × gross_receipts — applied separately to each of the three, then summed. The calculator above does exactly this.
Important: GET is collected from your gross, not added to the guest's bill (unlike sales tax in most US states). TAT and county-TAT can be passed through to guests as a line item. Many owners eat all three to keep listings price-competitive.
