Hawaii sales tax filing rules
Good to know
Hawaii's tax is the General Excise Tax (GET). Periodic returns are due the 20th; an annual reconciliation (Form G-49) is also required.
Filing Hawaii sales tax late
Hawaii charges a late-filing and late-payment penalty plus interest on any unpaid tax, and most states apply a minimum penalty even on a zero return. File on time — even a return with no tax due must be filed. Confirm current penalty amounts with the Hawaii Department of Taxation.
