- 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
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 0.49%.

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. As of January 2025, the state estimates it to be 6.25%.
So if your home has a market value of $300,000 (based on comparable sales), the assessed value is roughly $18,750 ($300,000 x .0625 = $18,750). Therefore, your tax rate only applies to that $18,750.
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.
