Kailua Kona's retail trade runs on tourism and agriculture, all of it at the 4.500% combined rate. The rate follows the transaction's sourcing, not the storefront's sign — three situations retailers here get wrong:

• In-store pickup vs. delivery: a picked-up order taxes at the store's rate; a delivered order follows Hawaii's sourcing rules to the customer's address
• Store locations near boundary lines: two branches of the same chain can sit in different local-tax jurisdictions — configure POS per location, never per brand
• Returns & exchanges: refund the tax actually charged at sale, even if the rate has since changed

• Untaxed deliveries: when no tax is charged, the buyer owes matching use tax to State of Hawaii
