How Property Tax Works

Conejos County, Colorado operates under the state's property tax system, which serves as the primary funding mechanism for local government services, schools, fire protection, and various special districts throughout the county. Property taxes in Conejos County fund essential services including public education, county operations, road maintenance, emergency services, and infrastructure improvements. The county follows Colorado's assessment methodology where residential properties are assessed at 6.765% of actual value, with commercial properties assessed at a higher rate.

The effective property tax rate in Conejos County varies significantly by location within the county due to the overlay of multiple special taxing districts. Based on available data, the county portion of the tax rate is 0.013980 (approximately 1.4%), but the total effective rate including school districts, fire districts, water districts, and other special assessments typically ranges from 0.6% to 1.2% of market value depending on your specific location. Property owners should note that their actual tax rate depends on which combination of taxing districts serve their property, making it essential to verify the specific rate applicable to your parcel through the Conejos County Assessor's office.

Pro tip: If you pay through mortgage escrow, your lender splits these payments across your monthly mortgage. If you pay directly, set calendar reminders to avoid late penalties.
Section 4

Supplemental Tax Bills

Supplemental property taxes in Conejos County are triggered by specific events that change a property's assessed value during the tax year. The primary triggers include change of ownership, completion of new construction, and improvements that add value to existing properties. When these events occur, the County Assessor determines the difference between the previous assessed value and the new assessed value, then applies the current tax rate to calculate the supplemental tax owed.

Supplemental taxes are calculated by taking the net increase in assessed value and multiplying it by the applicable tax rate for all taxing districts that serve the property. For example, if new construction adds $50,000 in market value to a residential property, the assessed value would increase by $3,383 (6.765% of $50,000). If the total tax rate is 60 mills, the supplemental tax would be approximately $203 annually ($3,383 × 0.060), prorated from the date the improvement was completed.

Escrow & Property Taxes

Most mortgage lenders in Conejos County require property tax escrow accounts for borrowers with less than 20% down payment or those who specifically request escrow services. Your lender collects monthly property tax payments along with your mortgage payment, then remits payment to the Conejos County Treasurer on your behalf. The escrow payment is calculated by dividing your annual property tax bill by 12 months, with lenders typically maintaining a cushion of 1-2 months of payments in the account.

Property taxes in Conejos County are payable in two installments: the first half is due by April 15th and the second half by October 15th of each year. Lenders typically pay the first installment in March or April and the second installment in September or October. Property owners should verify that their lender has made timely payments, as you remain ultimately responsible for ensuring taxes are paid even when using an escrow account. You can verify payments through the Conejos County Treasurer's website or by calling (719) 376-5446. If you pay taxes independently, you can pay both installments early or pay the full year by April 30th without penalty.
