Wyo. Stat. § 6-6-207

Whenever a permanent injunction issues against any person for maintaining a nuisance or against the owner or agent of any building kept or used for the purposes prohibited by this article, there shall be assessed against the building and the ground upon which it is located and against the person or persons maintaining the nuisance, and the owner or agent of the premises, a tax of three hundred dollars ($300.00). The assessment of the tax shall be made by the assessor of the county in which the nuisance exists and shall be made within three (3) months from the date of granting of the permanent injunction. If the assessor fails or neglects to make the assessment, it shall be made by the sheriff of the county and a return of the assessment shall be made to the county treasurer. The tax may be enforced and collected in the manner prescribed for the collection of taxes under the general revenue laws and shall be a perpetual lien upon all property, both personal and real used for the purpose of maintaining the nuisance. The payment of the tax does not relieve the person or building from any other penalties provided by law and when collected shall be applied and distributed in the manner prescribed by law for the application and distribution of monies arising from the collection of fines and penalties in criminal cases.
