Alabama Code Title 45. Local Laws § 45-44-244.04

When a return in form and substance satisfactory to the county director of revenue is not filed by an employer and the license fees are not paid to the county by such employer, the employee for whom no return has been filed and no payment has been made shall file a return with the county director of revenue on or before January 31 of each year showing in the return the gross receipts subject to license fees during the preceding calendar year. If for any reason all license fees of a person subject to the resolution or ordinance were not withheld by his or her employer from his or her compensation, such person shall file the return required by the county director of revenue and shall pay, at the time of the filing thereof, to the county the amount of license fees due under the ordinance or resolution.
