Ala. Code § 45-52-243.21
The Morgan County Commission is authorized to impose an additional excise tax on persons selling, distributing, storing, or withdrawing from storage for any purpose whatever, gasoline and motor fuel within the counties not to exceed one cent per gallon and to require every distributor, retail dealer, or storer of gasoline or motor fuel as herein defined to pay such excise taxes upon the selling, distributing, or withdrawing from storage for any use, gasoline and motor fuel in the county; provided that excise taxes levied pursuant to this subpart shall not be levied upon the sale of gasoline or motor fuel in interstate commerce, and provided further that if the excise tax imposed under this subpart upon the sale of such gasoline or motor fuel shall have been paid by a distributor or by a retail dealer or storer, such payment shall be sufficient, the intention being that the taxes shall not be paid but once. The excise taxes imposed pursuant to this subpart shall apply to persons, firms, corporations, dealers, storers, or distributors storing gasoline or motor fuel and distributing the same or allowing the same to be withdrawn from storage, whether such withdrawal be for sale or other use, provided that sellers of gasoline or motor fuel and its substitutes paying the taxes herein provided for may pay the same computed and paid on the basis of their sales as hereinafter required, and storers and distributors shall compute and pay such taxes on the basis of their withdrawals or distributions. The taxes herein provided for shall be in addition to any and all excise or other taxes imposed on gasoline or motor fuel or any device or substitute therefor, or on the business of selling, distributing, storing, or withdrawing from storage for any purpose, gasoline or motor fuel as herein defined; however, the Morgan County Commission shall have no authority to levy any tax upon any gasoline or motor fuel as herein defined when used in essential governmental functions by the State of Alabama or any agency thereof, or county governing agencies, municipalities, and boards of education.
