Under the Code, a privilege tax of three cents per gallon is imposed on all fuel sold or used in producing or generating power for propelling aircraft using aeronautical facilities in the State. The tax must be paid to the Secretary of State in the same manner and method and at the same time as is required for the collection of the gasoline tax that is imposed on all gasoline used in motor vehicles. The Code requires that a refund of one-and-one-half cents per gallon be made to airline operators who show proof within six months after purchase that they are operating interstate on scheduled operations. The bill would extend this refund to air carriers. The bill also would require the tax to be paid to the Department of Treasury, instead of the Secretary of State.
