The Legislature authorized the counties to adopt a surcharge on the general excise tax (GET) and use tax by ordinance at a rate of no greater than 0.5%. The following counties have adopted the surcharge:

  • City and County of Honolulu: The county surcharge at the rate of 0.5% is effective from January 1, 2007 to December 31, 2030.
  • County of Kauai: The county surcharge at the rate of 0.5% is effective from January 1, 2019 to December 31, 2030.
  • County of Hawaii: The county surcharge at the rate of 0.25% is effective from January 1, 2019 to December 31, 2019, and at the rate of 0.5% from January 1, 2020 – December 31, 2030.
  • County of Maui: The county surcharge at the rate of 0.5% is effective from January 1, 2024 to December 31, 2030.

The county surcharge is only added to activities taxed at the 4.0% rate. The county surcharge does not apply to activities taxed at the 0.5% rate (e.g., wholesaling) or the 0.15% rate (i.e., insurance commissions).

The county surcharge is computed and reported on Forms G-45 and G-49. Taxpayers who do business in more than one county must also complete Form G-75 and attach it to Forms G-45 and G-49.
