Ala. Code § 28-3-194

Each county and municipality is authorized to fix a reasonable privilege or license fee on retail, importer and wholesale licensees, for the purpose of covering the cost of administration, but not to generate revenue. Provided, however, that a county or municipality shall levy no license or privilege tax or other charge for the privilege of doing business as a beer wholesaler, importer or retailer which shall exceed one-half the amount of the state license fee.
