  • About This Answer

    To calculate the exact amount of property tax you will owe requires your property's assessed value and the property tax rates based on your property's address. Please note that we can only estimate your property tax based on median property taxes in your area. There are typically multiple rates in a given area, because your state, county, local schools and emergency responders each receive funding partly through these taxes. In our calculator, we take your home value and multiply that by your county's effective property tax rate. This is equal to the median property tax paid as a percentage of the median home value in your county.

Colorado Property Taxes 

Photo credit: ©iStock.com/Adventure_Photo

In Colorado, property taxes are used to support local services. In fact, 100% of property tax revenue stays within the county in which it is collected, meaning none of it goes to the state. That may be part of the reason that Colorado has some of the lowest residential property taxes in the country, with an average effective rate of just 0.55%.

Low property taxes can be a draw to live in Colorado or own a vacation home there. If you're thinking about purchasing property in Colorado or are looking to refinance, check out SmartAsset’s Colorado mortgage guide for details about mortgages in the Centennial State.

A financial advisor in Colorado can help you understand how homeownership fits into your overall financial goals. Financial advisors can also help with investing and financial plans, including taxes, homeownership, retirement and more, to make sure you are preparing for the future.

How Property Taxes in Colorado Work

Residential property taxes in Colorado depend on two things: the market value of the property and the total tax rates local taxing authorities levy. Taxing authorities include counties, cities, school districts and some special taxing districts set up for specific purposes. For example, this could be to fund a water or sanitation system.

Property is valued in two-year cycles, with values being based entirely on comparable sales. In other words, the price of similar homes sold in your area determine the value of your home. Notices of valuation are mailed to homeowners by May 1 every year, and homeowners who disagree with their home’s valuation have until June 1 to protest.

Tax rates in Colorado do not apply to market value, but rather to assessed value, which is equal to a fraction of the market value. That fraction, which is called the residential assessment rate, is recalculated regularly by the state. For the 2019 to 2020 tax year, the state estimates it to be 7.15%.

So if your home has a market value of $300,000 (based on comparable sales), the assessed value is roughly $21,450 ($300,000 x .0715 = $21,450). Therefore, your tax rate only applies to that $21,450.

Colorado Property Tax Rates

Taxing authorities in Colorado calculate tax rates based on how much revenue they need. That means rates change frequently as their revenue needs shift. Rates are expressed in mills, which are equal to $1 for every $1,000 of property value. A tax of 10 mills on a property with an assessed value of $10,000 is equal to $100 ($10,000 x 0.1).

An effective tax rate is the amount you actually pay annually divided by the value of your property. So if you pay $1,500 in taxes annually and your home’s market value is $100,000, your effective tax rate is 1.5%. The table below shows effective tax rates for every county in Colorado. It also displays median property tax payments and median home values for all counties.

Rank County Property Tax Rate School Rating Home Value Growth


Our study aims to find the places in the United States where people are getting the most value for their property tax dollars. To do this, we looked at property taxes paid, school rankings and the change in property values over a five-year period.

First, we used the number of households, median home value and average property tax rate to calculate a per capita property tax collected for each county.

As a way to measure the quality of schools, we analyzed the math and reading/language arts proficiencies for every school district in the country. We created an average score for each district by looking at the scores for every school in that district, weighting it to account for the number of students in each school. Within each state, we assigned every county a score between 1 and 10 (with 10 being the best) based on the average scores of the districts in each county.

Then, we calculated the change in property tax value in each county over a five-year period. Places where property values rose by the greatest amount indicated where consumers were motivated to buy homes, and a positive return on investment for homeowners in the community.

Finally, we calculated a property tax index, based on the criteria above. Counties with the highest scores were those where property tax dollars are going the furthest.
