The formulas

  • Sales tax = sale x (4% + local rate)
  • Nexus when counted sales are at least $100,000 or transactions are at least 200, in the current or preceding calendar year
  • Counted sales = direct sales + marketplace sales

How it works

Figures current as of November 2026.

Hawaii levies a general excise tax on the seller; the rate for retail sales is 4 percent. The tool multiplies the sale amount by the statewide base rate plus the local rate you enter (the county surcharge for the county of delivery) and shows the state and local parts separately. The local rate depends on where the goods are delivered.

A seller with no physical presence in Hawaii must register and collect once it has at least $100,000 of gross income or receipts from Hawaii, or at least 200 separate transactions, in the current or preceding calendar year. Sales you make through a marketplace facilitator count toward your own Hawaii threshold, together with your direct sales.

The general excise tax is imposed on the seller, not the buyer. A seller can pass it on to the buyer as a separate charge. The tool shows 4 percent of the sale plus the county surcharge you enter.

A seller with a physical presence in Hawaii, such as staff, an office or inventory, must collect regardless of the threshold. The tool does not decide whether a product is taxable or exempt; enter the taxable price.
