  • City and County of Honolulu: The county surcharge is effective from January 1, 2007 to December 31, 2030 at the rate of 0.5%.

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.
