Property Tax Bills

When will I receive my property tax bill?
Property Tax bills are mailed out on or before 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. Please note that taxpayers are responsible for payment of taxes regardless of billing. Even if you did not receive a tax bill for any reason, taxes are still due, and additional penalties will be assessed if paid late.

If you do not receive a tax bill by the end of October, or if you have any questions, please contact the Treasurer's office at (307) 332-1105 or

What is a mill levy?
A mill is one one-thousandth (1/1000) of a dollar. Therefore, there is $1 of tax for every thousand dollars of assessed value.

Who can assess taxes on my property?

Various entities are legally entitled to levy mills against properties in their districts subject to the limits provided by Wyoming law. These include local governments, school districts, colleges and other legally formed special districts. Certain taxing entities are entitled to assess taxes on all properties within Fremont County, regardless of tax district. Therefore, the total mill levy varies from tax district to tax district depending on the taxing entities within in your specific district.
