Property Tax bills are mailed out on or by October 10, after the Treasurer’s office receives the tax roll from the Assessors office. Tax bills are itemized to show:

Name and address of property owner as of January 1 of the tax year
Amount due
Due date of each installment
Distribution of tax throughout the county
Legal description of property

If you purchase a property or record a deed on or after January 1, you will not receive a tax bill in your name for that year. Taxpayers are responsible for payment of taxes regardless of billing. If you did not receive a tax bill for any reason, taxes are still due, and if paid late, interest will be charged.

What is a mill levy?

A mill is one one-thousandth of a dollar. Therefore there is $1 of tax for every dollar of assessed value. Various entities are legally entitled to charge mills against properties in their districts subject to the limits provided by Wyoming law. The mill levy varies from tax district to tax district depending on the taxing entities included in your district. The Fremont County Treasurer maintains a table showing the make-up of the all tax districts within Fremont County In addition, we also maintain a list of Assessed Values by Tax District, downloadable for your convenience.
