Section 39-14-103 - Imposition(a) Taxable event. The following shall apply: (i) There is levied a severance tax on the value of the gross product for the privilege of severing or extracting both surface and underground coal in the state. The severance tax imposed by this article may be in addition to other taxes, including but not limited to the ad valorem taxes imposed by W.S. 39-13-104.(b) Basis of tax (valuation). The following shall apply:(i) Coal shall be valued for taxation as provided in this subsection;(ii) The value of the gross product shall be the fair market value of the product at the mouth of the mine where produced, after the mining or production process is completed;(iii) Except as otherwise provided, the mining or production process is deemed completed when the mineral product reaches the mouth of the mine. In no event shall the value of the mineral product include any processing functions or operations regardless of where the processing is performed;(iv) Except as otherwise provided, if the product as defined in paragraph (iii) of this subsection is sold at the mouth of the mine, the fair market value shall be deemed to be the price established by bona fide arms-length sale;(v) In the event the product as defined in paragraph (iii) of this subsection is sold at the mouth of the mine without further movement or processing, the fair market value shall be the price established by bona fide arms-length sale less exempt royalties;(vi) In the event the product as defined in paragraph (iii) of this subsection is not sold at the mouth of the mine by bona fide arms-length sale, or, except as otherwise provided, if the product of the mine is used without sale, the department shall determine the fair market value of coal in accordance with paragraph (vii), (viii), (ix) or (x) of this subsection;(vii) For coal sold away from the mouth of the mine pursuant to a bona fide arms-length sale, the department shall calculate the fair market value of coal by multiplying the sales value of extracted coal, less transportation to market provided by a third party to the extent included in sales value, all royalties, ad valorem production taxes, severance taxes, black lung excise taxes and abandoned mine lands fees, by the ratio of direct mining costs to total direct costs. Nonexempt royalties, ad valorem production taxes, severance taxes, black lung excise taxes and abandoned mine lands fees shall then be added to determine fair market value. For purposes of this paragraph: (A) The sales value of extracted coal shall be the selling price pursuant to an arms-length contract. To the extent not included in the selling price pursuant to an arms-length contract, and to the extent that the following represent partial consideration for the value of the coal, sales value shall include the value per ton attributable to the extracted coal for any consideration provided to the seller in the form of heat content adjustments, price escalations or de-escalations, expense reimbursements, capital, facilities or equipment, services for mining, handling, processing or transporting the coal at or near the mine site, or any payment received for the current or past sale of extracted coal, by or on behalf of the purchaser. Sales value per ton shall include consideration provided for the deferral of extraction and sale in the taxable period in which the purchaser receives credit for the payment as a result of subsequent extraction and sale of the deferred production;(B) Direct mining costs include mining labor including mine foremen and supervisory personnel whose primary responsibility is extraction of coal, supplies used for mining, mining equipment depreciation, fuel, power and other utilities used for mining, maintenance of mining equipment, coal transportation from the point of severance to the mouth of the mine, and any other direct costs incurred prior to the mouth of the mine that are specifically attributable to the mining operation;(C) Total direct costs include direct mining costs determined under subparagraph (B) of this paragraph plus mineral processing labor including plant foremen and supervisory personnel whose primary responsibility is processing coal, supplies used for processing, processing plant and equipment depreciation, fuel, power and other utilities used for processing, maintenance of processing equipment, coal transportation from the mouth of the mine to the point of shipment, coal transportation to market to the extent included in the price and provided by the producer, and any other direct costs incurred that are specifically attributable to the mining, processing or transportation of coal up to the point of loading for shipment to market;(D) Indirect costs, royalties, ad valorem production taxes, severance taxes, black lung excise taxes and abandoned mine lands fees shall not be included in the computation of the ratio set forth in this paragraph. Indirect costs include but are not limited to allocations of corporate overhead, data processing costs, accounting, legal and clerical costs, and other general and administrative costs which cannot be specifically attributed to an operational function without allocation.(viii) For coal used without sale, or coal not sold pursuant to a bona fide arms-length agreement, the sales value for the purposes of paragraph (vii) of this subsection shall be the fair market value of coal which is comparable in the quality, quantity, terms and conditions under which the coal is being used or sold, both in the spot market and through longterm agreements negotiated within the previous twelve (12) months, multiplied by the respective number of tons used or sold for each reporting period;(ix) Notwithstanding paragraph (viii) of this subsection, the sales value for purposes of paragraph (vii) of this subsection for coal used as a feedstock in a coal enhancement process which has been subjected to normal processes necessary to achieve marketability, shall be the market value of comparable coal as determined by this paragraph. The market value of comparable coal attributable to feedstock coal shall be:(A) A representative selling price received or receivable which shall be determined by the first of the following subdivisions that is applicable, multiplied by the total feedstock tons used in each reporting period:(I) Arms-length price of comparable coal produced from the same mine and sold under comparable terms, or if a comparable coal price is not available from the same mine, the arms-length price of comparable coal produced from other mines in the area and sold under comparable terms;(II) Price reported to a public utility commission for comparable coal produced from the same mine and sold under comparable terms, or if a comparable coal price is not available from the same mine, the price reported to a public utility commission for comparable coal produced from other mines in the area and sold under comparable terms;(III) Other published or publicly available market prices for comparable coal produced from mines in the area and sold under comparable terms.(B) If subparagraph (A) of this paragraph is not applicable, then the sales value for coal used as a feedstock shall be the total arms-length selling price of the enhanced coal sold during the reporting period multiplied by the total of the enhanced tons sold.(x) In the event that unique or unusual circumstances exist such that the department or the taxpayer is unable to determine the value of the gross product of coal from a mine or mining claim by application of the methods provided in this subsection, the taxpayer may petition the department for approval to use an alternate valuation method. The department shall approve or deny the use of an alternate valuation method and shall so inform the parties within forty-five (45) days of the date the petition is filed.(c) Taxpayer. The following shall apply:(i) In the case of the gross product of all mines and mining claims produced under lease, the lessor is liable for the payment of ad valorem taxes on the product removed only to the extent of the lessor's retained interest under the lease, whether royalty or otherwise, and the lessee or his assignee is liable for all other ad valorem taxes due on production under the lease;(ii) Any taxpayer paying the taxes imposed by this article on any valuable deposit may deduct the severance taxes paid from any amounts due or to become due to the interest owners of such valuable deposit in proportion to the interest ownership;(iii) Any person extracting valuable products subject to this chapter and any person owning an interest in the valuable products to the extent of their interest ownership are liable for the payment of the severance taxes imposed by this article together with any penalties and interest.
