How Property Tax Works

Fremont County, Colorado operates under a property tax system that funds essential local services including schools, public safety, roads, and county operations. For the 2025 tax year, the county has established a general property tax rate of 12.325 mills (1.2325%) upon each dollar of assessed value. Property taxes are the primary funding mechanism for local government services and school districts throughout the county.

It's important to note that actual tax rates vary significantly by location within Fremont County due to special taxing districts such as fire protection districts, library districts, school districts, and other special assessments. Property owners may pay additional mill levies depending on which special districts serve their specific address. The total effective tax rate typically ranges from approximately 1.0% to 1.5% of assessed value, though this can vary based on your property's location and the combination of taxing districts that apply.

Supplemental Tax Bills

Supplemental taxes in Colorado are triggered by changes in property ownership or new construction that occurs after the January 1 assessment date. When property changes hands or new construction is completed mid-year, a supplemental assessment captures the difference between the old and new assessed values for the remaining portion of the tax year.

For example, if you purchase a home in June that was previously assessed at a lower value, or if you complete a home addition during the year, you may receive a supplemental tax bill. The supplemental tax is calculated by taking the difference between the new assessed value and the previous assessed value, multiplying by the applicable tax rate, and prorating for the remaining months in the tax year. This ensures that property taxes reflect current property values and ownership throughout the entire tax year.

Escrow & Property Taxes

Most mortgage lenders require property tax escrow accounts for borrowers with less than 20% down payment. Your lender collects monthly tax payments along with your mortgage payment and holds these funds in escrow until taxes are due. In Fremont County, property taxes are due by January 31st of the year following the assessment year.

Lenders typically pay your property taxes directly to the county treasurer before the January 31st deadline. You should receive annual escrow statements from your lender showing tax payments made on your behalf. It's important to verify that your lender has paid the correct amount and on time, as you remain ultimately responsible for ensuring your property taxes are paid. If you don't have an escrow account, you're responsible for making direct payments to the Fremont County Treasurer by the January 31st deadline to avoid penalties and interest charges.
