Notes for Hawaii

General Excise Tax (GET), not a classic retail sales tax. The base is unusually broad and can apply to business-to-business receipts.

Destination-based for most sales (high-level).

Use the typical-local checkbox to apply 4.5%instead of the 4% base. Or type a custom local from a city rate sheet. Highest local add-on reported in the 2026 table is 0.5%.
