For service providers in Hawaii, there are a few important things to know. Firstly, Hawaii doesn’t have what we think of as traditional U.S. sales tax. They have a general excise tax (GET). Rather than a tax on a sale paid by the buyer, GET is a tax for “the privilege of doing business” in the state of Hawaii and levied on the seller. GET is levied on the gross income of all types of business activity, unless specifically exempted by law. Sales taxes, on the other hand, typically are levied only on sales of tangible personal property and only at the retail level.
