How Property Tax Works

Rio Blanco County's property tax system serves as the primary funding mechanism for essential local services including schools, fire protection, libraries, parks and recreation, and county operations. Property taxes in Rio Blanco County are calculated based on the assessed value of your property multiplied by the applicable mill levy rates, which vary significantly depending on your specific location within the county due to overlapping special taxing districts.

For residential properties in tax year 2025, the assessment rate is 6.4% of actual value for most local government mill levies, with a separate assessment calculation for school district levies. This rate will increase to 6.95% beginning in 2026. Your total effective tax rate depends on which fire district, library district, and other special districts serve your property location. Rates can vary considerably between areas served by different combinations of districts such as Meeker Regional Library versus Rangely Regional Library, or Rio Blanco Fire versus Rangely Rural Fire districts.

When Are Property Taxes Due?

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 taxes in Rio Blanco County are triggered when property changes ownership or when new construction increases a property's assessed value during the tax year. These taxes cover the difference between what was originally assessed and what should have been assessed based on the property's new value or ownership status.

When supplemental taxes are levied, they are calculated by applying the current mill levy rates to the difference in assessed value, prorated for the portion of the tax year remaining after the triggering event. For example, if you purchase a home in January that was previously under-assessed, you may receive a supplemental tax bill covering the assessment difference for the remainder of that tax year. The supplemental amount is added to your regular property tax obligation and follows the same payment schedule and penalty structure as regular property taxes.

Escrow & Property Taxes

Most mortgage lenders in Rio Blanco County require borrowers to maintain an escrow account for property tax payments, especially for loans with less than 20% down payment. Your lender collects monthly escrow payments as part of your mortgage payment, typically 1/12 of your annual property tax obligation plus a small cushion as allowed by federal law.

Property taxes in Rio Blanco County are typically due in mid-October each year. Your mortgage servicer will pay these taxes directly to the Rio Blanco County Treasurer's Office from your escrow account before the due date. Lenders must provide an annual escrow analysis showing how your payments were applied and any adjustments needed for the coming year. If your property taxes increase due to reassessment or mill levy changes, your monthly escrow payment may be adjusted accordingly. You can verify your tax payments were received by checking with the Rio Blanco County Treasurer's Office at 555 Main Street, Meeker, CO 81641.
