These are state-level averages. Individual counties and cities can vary significantly — a home in Austin's urban core may have a far higher effective rate than the Texas state average, for example. For the most accurate estimate, get the exact millage rate from your county assessor and override the rate field above.
How to use this calculator
Enter your home value — this is your home's market value (typically close to what you'd sell for today, or what you paid). The state dropdown is pre-selected to Colorado, and the rate field is pre-filled with the state's average effective property tax rate of 0.55%.
For a more precise estimate, override the rate with your local millage rate from your county assessor's website or your most recent property tax bill. In Colorado, rates vary considerably by county and city — the state average is a starting point, not your exact number.
You'll see your annual tax, monthly tax (the amount typically escrowed with your mortgage), and how Colorado's rate compares to the national average and to other states.
How it works
Colorado's 0.55% effective property tax rate is less than half the national average. It ranks 49th out of 51 US states, putting it in the bottom 10 lowest. On the state's median home value of $555,000, that produces an annual property tax bill of roughly $3,053.
Property tax is a local tax, not a state tax — most of what you pay goes to your county, city, school district, and other local taxing authorities. The "state average" rate you see here is really a blend of all those local rates, weighted across Colorado's counties. Your specific home's rate could be meaningfully higher or lower depending on where you live.
Rates are expressed as an effective property tax rate: the actual dollar tax divided by the home's market value. Many counties also publish a millage rate in mills (one mill = 0.1% = $1 per $1,000 of assessed value). They're two ways of writing the same tax.
Most Colorado homeowners pay property tax through escrow: your lender collects 1/12 of the annual bill with each mortgage payment, holds it, and sends it to the county when the bill comes due. If you own outright, you typically pay the county directly in one or two installments per year.
