Colorado Property Tax Guide

Colorado homeowners enjoy some of the lightest property taxes in the country, with an average effective rate of about 0.52% of home value, well below the national average near 0.9%. The bill isn't set in Denver; it's assessed and billed locally by each county assessor and treasurer, and the rate reflects a mix of school districts, county government, municipalities, and special districts where the property sits. Because of that local layering, two homes of equal value in different counties can carry meaningfully different bills.

The math runs in stages. The assessor estimates your home's market value, multiplies it by a state assessment rate to get the assessed value, then local mill levies are applied to that assessed value to produce the tax owed. Colorado offers relief programs, including a homestead exemption for qualifying senior and disabled-veteran homeowners that reduces the taxable portion of a primary residence. To rough out a bill yourself, take your market value, apply the residential assessment rate to get assessed value, and multiply by the combined local mill levy expressed as a rate.

Colorado Property Tax FAQ

How is a Colorado property tax bill calculated?
The county assessor first determines your home's market value, then applies the state residential assessment rate to arrive at an assessed value. Local mill levies from the county, schools, and special districts are applied to that assessed value to produce the tax. Because assessed value is only a fraction of market value, the effective rate on full home value averages around 0.52%.
Why are Colorado property taxes so low compared to other states?
Colorado's average effective property tax rate is about 0.52%, well below the national average near 0.9%, partly because the residential assessment rate keeps the taxable assessed value well below market value. Rapidly rising home values also mean that even modest rates generate substantial revenue, which can hold mill levies down. The actual rate still varies by county and district.
What is Colorado's homestead exemption?
Colorado offers a homestead property tax exemption for qualifying senior homeowners who have lived in their home long enough to meet the program's requirements, and a parallel exemption for qualifying disabled veterans. It reduces the portion of a primary residence's value that is subject to tax, lowering the bill. Eligibility rules and application deadlines are set by the state and administered through county assessors.
Who sets and collects property tax in Colorado?
Property tax is a local matter in Colorado. The county assessor values your property, local taxing entities such as school districts and municipalities set their mill levies, and the county treasurer sends the bill and collects payment. The state defines the assessment framework, but the dollar amount you owe is built from the levies of the districts your home falls within.
