Section 39-17-203 - Imposition(a) Taxable event. The following shall apply: (i) There is levied and shall be collected a license tax on all diesel fuels used, sold or distributed for sale or use in this state except for those fuels exempted in W.S. 39-17-205;(ii) Repealed by Laws 2015, ch. 46, § 2.(iii) A terminal operator or bulk plant operator may rely on the representation made by the purchaser of motor fuel or the purchaser's agent concerning the destination state of the motor fuel. A purchaser is liable for any tax due as a result of the purchaser's diversion of fuel from the represented destination state;(iv) Any user not otherwise required to be licensed and report the tax levied pursuant to this section under the provisions of W.S. 39-17-207 or 39-17-206 shall be required to be licensed and report all taxes due under this section pursuant to the provisions of W.S. 39-17-206 and 39-17-207.(b) Basis of tax. The following shall apply: (i) The state of Wyoming preempts the field of imposing taxes upon sales and use of diesel fuels and no city, town or county may levy or collect taxes upon the sales or use of diesel fuels;(ii) The taxes imposed on diesel fuel shall be conclusively presumed to be a direct tax on the ultimate or retail consumer. When taxes are paid by any person other than the ultimate or retail consumer, the payment shall be considered as precollected and as an advance payment for the purpose of convenience and facility to the consumer and shall thereafter be added to the price of the diesel fuel and recovered from the ultimate or retail consumer, regardless of where or how the taxable fuel is ultimately consumed;(iii) When a supplier, distributor, refiner, importer or exporter imports diesel fuel into or exports diesel fuel from the state of Wyoming in the fuel supply tanks of motor vehicles, the amount of diesel fuel consumed in the vehicles on Wyoming highways shall be deemed to be the product of the total amount of the diesel fuel consumed in his entire operations within and without this state times the total number of miles traveled on the highways within this state divided by the total number of miles traveled within and without the state. In the absence of mileage records, the department may by rule promulgated pursuant to W.S. 39-17-202(a) adopt the mileage basis for determining the taxable use of diesel fuel used in those motor vehicles which travel regularly over prescribed courses on and off the highways within the state of Wyoming. In the absence of records showing the number of miles actually operated per gallon of diesel fuel consumed, it shall be presumed that not less than one (1) gallon of diesel fuel was consumed for every four (4) miles traveled;(iv) A Wyoming licensed supplier, distributor, refiner or importer who is unable to recover the license taxes due from a bulk sale to a licensee who is other than an end-user and is not owned, rented or leased by the supplier, distributor, refiner or importer requesting the credit is not liable for the taxes and may credit the amount of unpaid taxes against a later remittance of taxes required under W.S. 39-17-204(a)(i). The department shall promulgate rules to implement this paragraph.(c) Taxpayer. The following shall apply:(i) The taxes imposed on motor fuel shall be conclusively presumed to be a direct tax on the ultimate or retail consumer. When taxes are paid by any person other than the ultimate or retail consumer, the payment shall be considered as precollected and as an advance payment for the purpose of convenience and facility to the consumer and shall thereafter be added to the price of the motor fuel and recovered from the ultimate or retail consumer, regardless of where or how the taxable fuel is ultimately consumed;(ii) A terminal operator, distributor or supplier may rely on the representation made by the purchaser of motor fuel or the purchaser's agent concerning the destination state of the motor fuel. A distributor or supplier is liable for any tax due as a result of the distributor's or supplier's diversion of fuel from the represented destination state;(iii) Every person who sells or offers to sell to the retail trade diesel fuels for use in motor vehicles shall conspicuously display a sign stating the price per gallon including all applicable taxes. The provision of this paragraph shall not apply to key lock or card lock fuel dispensing systems.Amended by Laws 2015 , ch. 46, § 2, eff. 7/1/2015.
