Ala. Code § 40-11-4
All taxes, unless otherwise provided by law, shall become due and payable on October 1 in each year, and shall become delinquent if not paid before January 1 succeeding, except in cases when parties have moved or are about to move from the county, and except in cases when parties are closing out or going out of business, and except in cases where insolvency is impending, and except in cases where goods, wares, and merchandise are advertised for sale at auction, bankrupt, insolvent, assignment, or fire sales, or where said goods, wares, and merchandise are advertised for sale for the satisfaction of creditors, or as closing out or going out of business sales, or in any way where a person is disposing of substantially all of his taxable property in the county, in which cases such taxes shall become due and payable at once. Advertisements in the newspapers or otherwise of a sale of any personal property as a closing out sale, fire sale, bankrupt sale, or any sale of like character shall be prima facie evidence that the collection of taxes due on such property or any other property so advertised is endangered within the meaning of this section. Notice to any tax collector by the Department of Revenue, a tax assessor, deputy tax assessor, tax agent, license inspector, or any other official of this state or any county thereof that any person is about to move a whole or any part of his personal property from this state shall be prima facie evidence that the collection of the taxes due or to become due by said person on such property or other property is endangered; and, upon failure of the tax collector to act as provided in Section 40-5-31, he shall be liable on his bond for any neglect to immediately collect the taxes due, by levy and sale or otherwise.
