If you're moving to Colorado or buying a home in the Centennial State, understanding property taxes is an important part of the process. While Colorado is known for its breathtaking landscapes and outdoor lifestyle, it also boasts some of the lowest property tax rates in the country. But how does Colorado property tax work?
In this guide, we’ll break down everything you need to know about property taxes in Colorado, including how they’re calculated, when bills are due, and what to expect in different counties. Whether you're a first-time homebuyer or relocating from another state, this will help you make informed decisions about your home purchase.
The average property tax in Colorado is among the lowest in the U.S. for homeowners. Colorado’s statewide effective property tax rate is approximately 0.5%, compared to the national average of 1.1% for the median owner-occupied home.
In 2020, the Colorado property tax was $1,956 per capita, and the U.S. average was $1,810. The median bill for Colorado property taxes for owner-occupied homes was $1,868 compared to the U.S. average of $2,551.
This means that for a home valued at $558,000, the state median list price, the Colorado property tax would be around $2,790 per year. The U.S. average for a home of the same value would be $6,138.
In 2020, the Lincoln Institute of Land Policy ranked Colorado 15th in per capita property taxes. Residential property was assessed at 6.765% in 2022, and most non-residential property was assessed at 27.9%. Among each state's largest cities, the effective Denver property tax rate was the 4th lowest at 0.52%.
Colorado property tax is determined at the county level and collected by the county treasurer. The key agencies involved include:
Every year, taxing entities determine the revenue needed for the following year. The necessary revenues are divided by the total assessed value to determine a mill levy or tax rate for each entity.
In Colorado, special districts receive 18% of the state's total property tax revenue. That's about 5x the U.S. average. A large share goes to Metro Districts set up by developers. They are used to issue bonds that finance infrastructure in new master-planned communities and subdivisions.
Unlike some states that tax the home’s market value, Colorado property tax is based on the property's assessed value, which is a percentage of the home's market value.
A home's market value is determined based on comparable sales. This is multiplied by the assessment rate to determine the assessed value. The county then applies the mill levy to determine the total assessed value and tax bill.
Because Colorado reassesses properties every odd-numbered year, values fluctuate based on comparable sales, which can impact your tax burden.
In 2020, Colorado repealed a property tax law from 1983 that placed a disproportionate amount of the total property tax burden on non-residential properties. The non-residential assessment rate was 29% of market value versus the 7.15% residential assessment rate. With the repeal of the Gallagher Amendment, Colorado froze assessment rates at 2020 levels but authorized the CO legislature to lower the assessment rate. Increases must be approved by voters.
Beginning in 2025, there will be two assessment rates for residential properties:
2025 Assessment Rates - (*projected as of January 1, 2025)
*Final rates will be based on the growth rate of actual values statewide from 2024 to 2025. If statewide actual value growth is higher than 5%, these rates will be lower.
| Classification | Assessment Rate |
| Residential: Local Government | 6.25% |
| Residential: Schools | 7.05% |
| Vacant Land | 27% |
| Commercial | 27% |
| Commercial: Lodging | 27% |
| Industrial | 27% |
| Agricultural | 27% |
| State Assessed Renewable Energy | 27% |
A mill levy is the rate at which properties are taxed. One mill = $1 per $1,000 of assessed value.
If a total mill levy is 80 mills, it's equal to $80 per $1,000 of assessed value. You would multiply 0.080 (80 mills) by your assessed value to determine your tax rate.
Tax rate is a way of expressing this as a percentage.

Colorado property tax is calculated using this formula:
Actual Value x Assessment Rate = Assessed Value x Mill Levy = Colorado property taxes due
For Colorado property tax year 2024 (paid in 2025), the Colorado Legislature approved a one-time $55,000 value adjustment for residential properties.
(Actual Value - Value Adjustment) x Assessment Rate = Assessed Value x Mill Levy = Colorado property taxes due
Here's an example for a home with a market value of $450,000, an assessment rate of 6.7%, and a 92 mill levy.
$450,000 - $55,000 = $395,000 x 0.067 (6.7%) = $26,465 (property's assessed value)
$26,465 x 0.092 (92 mills) = $2,435 property tax bill
Generally, your Colorado property tax rate is affected by multiple taxing authorities. The total Colorado property tax rate, or total mill levy, for a property is determined by adding the tax rates for each relevant tax entity.
Here are recent Colorado property tax rates by location or tax entity. Note that your total tax rate will depend on which tax entity boundaries apply to your location.
In 2023/2024, school districts in Colorado had tax rates ranging from 2.216 mills to the state cap of 27 mills. Districts at or near the cap included most in the Denver and Pueblo metropolitan areas, a cluster in the San Luis Valley, and a rural area in the northern Eastern Plains area. Districts with the lowest taxes are in wealthy areas with high property values, including near resort towns like Aspen and Telluride or gas and oil producing areas in the San Juan Basin, Piceance Basin, and Weld County.
Your Colorado property tax bill reflects the taxes owed for the previous year. This means the 2024 property tax year is paid in 2025. Tax bills are mailed soon after January 1.
You may make a single payment by April 30 or pay your tax bill in two equal installments.
You can pay your Colorado property tax through your county treasurer. You typically have multiple ways to make a property tax payment:
If you have a mortgage, your lender may collect property taxes through escrow as part of your monthly mortgage payment. The property tax bill should then be paid on your behalf. If you pay taxes through escrow, you will pay 1/12 of your estimated tax bill each month.
Late payments may result in interest charges and possible tax liens.
Colorado property tax bills are due in one payment or in two equal payments by the following dates:
Some property owners qualify for property tax exemptions or relief programs:
All homeowners in Colorado receive a homestead exemption for their share of property taxes. The exemption is 10% of the home's value up to $700,000.
