There is levied, in addition to all other taxes of every kind now imposed by law, and shall be collected as herein provided, a privilege or license tax against the person on account of the business activities and in the amount to be determined by the application of rates against gross sales, or gross receipts, as the case may be, as follows:
Where any used part including tires of an automotive vehicle or a truck trailer, semitrailer, or house trailer is taken in trade, or in a series of trades, as a credit or part payment on the sale of a new or rebuilt part or tire, the tax levied herein shall be paid on the net difference, that is, the price of the new or used part or tire sold less the credit for the used part or tire taken in trade, provided, however, this provision shall not be construed to include batteries.
Where any used automotive vehicle or truck trailer, semitrailer, or house trailer is taken in trade or in a series of trades, as a credit or part payment on the sale of a new or used vehicle, the tax levied herein shall be paid on the net difference, that is, the price of the new or used vehicle sold less the credit for the used vehicle taken in trade.
Sales of automobiles, motorcycles, trucks, truck trailers, travel trailers, campers, housecars, or semitrailers that will be registered or titled outside Alabama, that are exported or removed from Alabama within 72 hours by the purchaser or his or her agent for first use outside Alabama are subject to Alabama sales tax in an amount equal to only the state automotive sales tax rate, unless the sales tax laws of the state in which the purchaser will title or register the vehicle allows an Alabama resident to purchase a motor vehicle for first titling and registering in Alabama without the payment of tax to that state. However, in no case shall the amount of Alabama state sales tax due on a motor vehicle that will be registered or titled for use in another state exceed the amount of sales tax that would otherwise have been due in the state where the vehicle will be registered or titled for first use. In order to qualify as a travel trailer, camper, or housecar that will be registered or titled for use in another state, the purchaser must provide documentation to the seller that the purchaser is not a resident of Alabama as required by the Department of Revenue. No such proof is required in the sale of an automobile, motorcycle, truck, truck trailer, or semitrailer, excluding a travel trailer, camper, or housecar. The tax collected under this export provision shall be Alabama sales tax and shall exclude county and municipal sales tax. On January 1, 2016, and each January 1 thereafter, the Alabama Department of Revenue shall publish to the state's website a list of states that do not allow drive out provisions to Alabama residents. Should the list, required by this subsection and relied upon by the taxpayer, be incorrect, the taxpayer shall be relieved from the liability concerning the miscollection of the state automotive sales tax. Sales of all other vehicles such as mobile homes, motor bikes, all terrain vehicles, and boats do not qualify for the export exemption provision and are taxable unless the dealer can provide factual evidence that the vehicle was delivered outside of Alabama or to a common carrier for transportation outside Alabama. In order for the sale to be exempt from Alabama tax, the information relative to the exempt sale shall be documented on forms approved by the Revenue Department.
Of the total $.02 tax on each dollar of sale provided hereunder, 58 percent of the total tax generated by this subdivision (4) shall be deposited to the credit of the Education Trust Fund and 42 percent of the total tax generated by this subdivision (4) shall be deposited to the credit of the State General Fund.
