This license covers the state's general excise tax, which is applied to most business activities at a state-set general excise tax rate (slightly higher in Oahu).

Hawaii's high cost of commercial space makes home-based businesses particularly attractive. The state's cottage food law specifically allows home-based food production and direct sales.
