78.12  Reports to department; computation of tax. (1) Gallons to be reported. For the purpose of the administration of this section, each receipt, shipment or delivery of motor vehicle fuel shall be reported in U.S. standard liquid gallons (231 cubic inches). (2)  Reports of licensees. Each licensee shall, not later than the last day of each month, file a report for the month before the month during which the report is due. (3)  Reports of others. Any person, including a terminal operator, who is not a licensee and who either uses any motor vehicle fuel in this state or who has possession of any motor vehicle fuel (other than that contained in the ordinary fuel tank attached to a motor vehicle) upon which the motor vehicle fuel tax has not been paid or the liability therefor has not been incurred by any licensee in this state shall file a report and pay the tax on that motor vehicle fuel and shall be subject to this subchapter in the same manner as is provided for licensees. (4)  Computation of tax. At the time when the tax is due under sub. (5), the licensee shall compute that tax as follows:(a) For gasoline:1. Subtract the number of gallons under s. 78.01 (2r) for the taxable period from the number of gallons received during the taxable period.2. Subtract from the amount under subd. 1. an amount equal to 0.00625 multiplied by the number of gallons under subd. 1.3. Subtract from the amount under subd. 2. an amount equal to 0.0005 multiplied by the number of gallons under subd. 1.4. Multiply the number of gallons under subd. 3. by the rate published under s. 78.015 as increased under s. 78.017. 5. On October 1, 2021, the percentages used to calculate the amounts to be subtracted from the computation of the tax under subds. 2. and 3. are doubled.(b) For diesel fuel:1. Subtract the number of gallons under s. 78.01 (2r) for the taxable period from the number of gallons received during the taxable period.2. Multiply the number of gallons under subd. 1. by the rate published under s. 78.015 as increased under s. 78.017.  (5)  Payment of tax. Licensed suppliers shall pay taxes on motor vehicle fuel no later than the 15th day of the month for motor vehicle fuel sold during the previous month. At the option of a wholesaler distributor, a licensed supplier shall allow the wholesaler distributor to delay paying the tax to the licensed supplier until the date that the tax is due to this state. A wholesaler distributor who makes delayed payments shall make the payments by electronic funds transfer. If a wholesaler distributor fails to make timely payments, the licensed supplier may terminate the right of the wholesaler distributor to make delayed payments. Each licensed supplier shall notify the department of each wholesaler distributor who makes delayed payments of the tax. The department may require any wholesaler distributor who makes delayed payments of the tax to furnish the department a surety bond payable to this state in an amount not to exceed 3 times the highest estimated monthly tax owed by the wholesaler distributor. Whenever the wholesaler distributor pays the licensed supplier, the licensed supplier shall credit the wholesaler distributor's account for the amount of tax reduction that results from the calculation under s. 78.12 (4) (a) 2.History:  1973 c. 333; 1975 c. 180, 421; 1977 c. 418; 1979 c. 221; 1985 a. 153; 1987 a. 399; 1991 a. 39, 316; 1993 a. 16, 437; 1997 a. 27; 2005 a. 85; 2019 a. 9; 2021 a. 58.Sub.
