Ala. Code § 40-7-7
When a taxpayer resides out of the county, or by reason of any infirmity or disability is unable to attend any of the appointments of the assessor, or is a woman, such taxpayer may send in his or her list, duly sworn to by any other person or by mail, postage prepaid, or such list may be rendered by an agent having knowledge of his or her taxable property. The land and the improvements thereon must be separately listed. Any person who knowingly subscribes to a list of property which is false is guilty of a misdemeanor and shall upon conviction be subject to a fine of not more than $500 and may also be imprisoned in the county jail or sentenced to hard labor for not more than six months.
Any person who owns personal property may make a return of such property to the tax assessor by mail or by an authorized agent having knowledge of such taxable property.
