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.
