How Property Tax Works

Kit Carson County property taxes fund essential local services including public education, county operations, fire protection, library services, and various special districts throughout the rural eastern Colorado county. Property taxes are calculated based on the assessed value of your property multiplied by the mill levy rate, which varies significantly by location within the county depending on which special taxing districts serve your property.

For the 2025 tax year, Kit Carson County's property tax rate is 6.4%, with rates scheduled to increase to 6.95% beginning in 2026. The county implemented an additional 3.184 mill increase in 2025 to support county services. Your actual effective tax rate will depend on your specific location within Kit Carson County, as different areas are served by different combinations of school districts, fire districts, library districts, and other special taxing authorities that each add their own mill levies to your total tax bill.

Section 4

Supplemental Tax Bills

Supplemental property taxes in Kit Carson County are triggered when there is a change in property ownership, completion of new construction, or significant improvements that increase the assessed value after the January 1st assessment date. These taxes cover the period from when the change occurred until the end of the current tax year.

Supplemental taxes are calculated by determining the difference between the old assessed value and the new assessed value, then applying the current mill levy rate to that difference, prorated for the remaining months in the tax year. For example, if you purchase a home in July that was previously assessed at $150,000 but now has a market value requiring a $200,000 assessment, you would owe supplemental taxes on the $50,000 difference for the remaining 6 months of the tax year. With a 64 mill rate, this would result in approximately $1,920 in supplemental taxes ($50,000 × 0.064 × 0.5 years).

Section 5

Escrow & Property Taxes

Most mortgage lenders in Kit Carson County require property tax escrow accounts to ensure timely payment of property taxes. Your lender collects approximately 1/12th of your estimated annual property tax bill each month along with your mortgage payment. The escrow account is analyzed annually, and your monthly payment may be adjusted based on actual tax bills and account balance.

Property taxes in Kit Carson County are paid in two installments: the first half is due April 30th, and the second half is due June 15th. Your mortgage company will typically pay these directly from your escrow account. If your total annual tax bill is $25 or less, the full amount is due on April 30th. You can verify escrow payments and view tax payment history through the Kit Carson County Treasurer's office or by contacting your mortgage servicer directly.
