Many homeowners across the Denver metro area have recently received their 2025 property tax assessments, and for some, the new valuations have come as a surprise. My own property assessment come in surprisingly high and I’ve heard from many of my clients that they feel the same way. If you believe your property’s assessed value is too high, it’s essential to know that you have the right to appeal. This guide will walk you through the process of understanding your assessment and how to contest it effectively.
Understanding Your Property Tax Assessment
In Colorado, property tax assessments are conducted every two years. The 2025 assessments are based on the market value of your property as of June 30, 2024. Assessors use sales data from comparable properties sold between July 1 2022, and June 30, 2024, to determine your property’s value. It’s important to note that assessors do not inspect the interior of homes. They assume average condition unless informed otherwise.
Reasons You May Want to File an Appeal
You may have valid reasons to appeal your property tax assessment if:
- Overvaluation: Comparable homes in your area have sold for less than your assessed value
- Incorrect Property Details: The assessor’s records contain errors regarding your property’s size, number of rooms, or other characteristics
- Physical Condition: Your property has issues, such as structural problems or deferred maintenance, that are not reflected in the assessment
- Unfair Comparisons: The assessment is based on sales of properties that are not truly comparable to yours
Key Dates to Know
For the 2025 assessment cycle, appeals must be filed between May 1 and June 9, 2025. If you miss this window, you’ll need to wait until the next assessment cycle or pursue an abatement, which follows a different process and timeline.
How to Appeal Your Assessment

- Gather Evidence. Collect data on recent sales of comparable properties in your area
- Document Property Conditions. Take photos and gather reports that highlight any issues that may lower your home’s value
- Submit Your Appeal. File your appeal with your county’s assessor’s office before the June 8 deadline
- Present Your Case. Be prepared to present your evidence and explain why your property has been overvalued
