If you are a residential property owner in Jefferson County, you likely received, or will soon receive, a Notice of Value alerting you to a change in your property's assessed value in 2023. Colorado law mandates Assessors to revalue all real estate in their counties based on a specific appraisal date, which for this year was June 30, 2022. Previous valuations are disregarded, and only sales from July 1, 2020, to June 30, 2022, are considered for analysis. The NOV postcard you receive represents the new value determined from sales in that study period. 


You will likely notice a few things this year. First, property values across Colorado are up. Second, your NOV includes a tax estimate that was previously not required, and may appear higher than you expected. We understand that both of these things may seem alarming at first, and we want to provide you with the information you need and reassurance about what those values mean. To better understand your property valuation and prepare for a potential appeal, we encourage you to take advantage of our resources, including our comparable sales search tool, available on our website. We also encourage you to read the materials we have provided on this page with more information about how we calculate values, what your tax estimate means, and how to use the comparable sales search to prepare to file an appeal if you choose to do so. Our team is here to assist you and answer any questions or concerns you may have.
