Lower your Denver County property taxes
The City and County of Denver values every home in odd-numbered years, and the 2027 reappraisal will reset values to the market as of June 30, 2026. In 2025, median residential values moved anywhere from −5% to +5% across the city, so a citywide trend says little about whether your own value is right. 30% of first-year savings, only if you save.
What a too-high value costs you
If your home is assessed at $600,000 but similar homes point to about $560,000, you're taxed on $40,000 too much. At a 0.52% rate that's about $208 a year. Our fee would be $62; you'd keep $146.
What gets missed in Denver
- The 2027 reappraisal. Every home gets a new value in May 2027, based on sales up to June 30, 2026. Each reappraisal is a fresh chance to protest.
- Neighborhood swings. Denver's 2025 changes ranged from −5% to +5%. A model built on the wrong pocket of sales can miss in either direction.
- Condos and townhomes. Attached homes are often compared with sales in buildings with different amenities, HOA costs or age.
- Condition. An original kitchen, an aging roof or a cracked foundation doesn't show up in the assessor's records.
Insider tip: Denver lets you protest online through its property search at denvergov.org/property. File by June 8 and attach your comparable sales and photos with the protest.

Exemptions to check
If you're 65 or older and have owned and lived in your home for at least 10 years, the senior exemption takes 50% off the first $200,000 of actual value. Qualifying disabled veterans get the same exemption. For 2026, the local-government part of your tax is figured on your value minus 10% of the first $700,000. We check your exemptions free at sign-up.
Denver questions
How do I protest in Denver?
Online through Denver's property search, or in writing or in person, by June 8. Include your reasons and evidence such as recent sales of similar homes.
What if I disagree with the Assessor's decision?
In 2025 Denver used the later reappraisal-year schedule (required for counties over 300,000 people): decisions by August 15 and Board of Equalization appeals by September 15. The same schedule applies in 2027.
I missed the deadline. Now what?
Denver says you can ask for a refund on up to two prior years you didn't protest, using a petition for abatement or refund of taxes. Otherwise, the next chance is the 2027 reappraisal.
