What happens at a Board of Equalization hearing in Denver County?
If your protest progresses to a hearing, it's your time to shine. Present your evidence and make your case before the Board of Equalization. Speak confidently and passionately, but remember: the board members are human too, so a touch of empathy goes a long way. The taxpayer must be notified of these hearings, must be given the opportunity to attend, and must be allowed to present witnesses and other evidence. After the hearing, you'll receive the board's decision. If they rule in your favor, congratulations! You've successfully navigated the tax protest process.
How much can I save by appealing my property taxes in Denver County?
The amount you can save depends on how much your property was overvalued and whether your appeal is successful. Statistics show that about 25% of homes in America are unfairly overassessed, and pay an average of $1,346 too much in property taxes every year. In Denver County, with a median home value of $636,400 and an effective tax rate of 0.48%, even a 10% reduction in assessed value could save you over $300 annually. The key is presenting strong evidence showing your property's true market value is less than the assessor's determination.
What evidence do I need for a Denver County property tax appeal?
Evidence is the lifeblood of a successful tax protest. Without it, your protest might crumble like a house of cards. So, do your homework and gather strong evidence supporting your incorrect assessment claim. The reasons to appeal generally fall into two categories: a discrepancy with the physical characteristics of the property and proof that similar properties have actually sold for less than what is shown in the assessor's valuation. You should gather recent sales data, property comparisons, and appraisal reports. Moye recommended calling your real estate agent and asking them to find you comparable home sales from that same time frame.
What if I miss the June 1st deadline to appeal in Denver County?
If you have missed the deadline for filing a protest, you may still have the ability to file abatement. Contact us to learn more about your options. Additionally, You get 2 chances to appeal this value (May 2026 and May 2026) since property values are set for two-year periods. If you miss the deadline in the reappraisal year, you may have another opportunity to appeal the following year during the intervening year. However, it's always best to appeal as soon as possible if you believe your property is overvalued.
How does Denver County's property tax rate compare to other Colorado counties?
Denver County has an effective property tax rate of around 0.48% of a home's assessed value, which places it near the middle of the pack among metro area counties. Douglas County is the lowest in the Denver metro, which can make a meaningful difference in affordability. Adams County tends to be the highest, so buyers looking there should account for slightly higher annual taxes.

For a typical Denver home, if you purchase a home for $600,000 in Denver, you can expect an annual property tax bill of roughly $2,800 to $3,000.
