The special tax shall be determined as follows: (I) For property used for wildlife management purposes, the tax shall be equal to the amount of the ad valorem tax for that property had it been levied and assessed based upon the taxable value of agricultural land of similar productive value under W.S. 39-13-101(a) and paragraph (b)(x) of this section;(II) For property used for any other purpose, the tax shall be equal to the amount of the ad valorem tax for that property had it been levied and assessed based upon the taxable value of similar property valued at fair market value as provided by paragraph (b)(ii) of this section.(B) For the purpose of valuation, assessment, collection, distribution of tax collected and all other matters related to this special tax, the administration of this tax shall be as if this tax were an ad valorem tax on the property.

The department may base the assessment upon the returns of the several railroad companies;(C) In case any company fails or refuses to make the required statement, the department shall fix the fair market value of the rail cars, and in determining the number and value of cars the department, insofar as practicable, shall harmonize the statements of the several rail car companies, with respect thereto and the assessment shall be included in the records and proceedings of the department.(xvii) For the valuation of vacant land within a platted subdivision development, the county assessor shall consider the value of the property through the use of present worth appraisal methodology upon request of the property owner.(c) Taxpayer.
