Below you will find the link to begin the process of filing your online appeal.  Prior to filling out the form, we would like to provide you with some information that we hope will assist you in this process.

The real property tax assessment appeal period is from May 1 to June 2.

2008 Notices of Valuation (NOV) were sent May 1, 2008 to property owners in Boulder County who have seen a value or classification change. For those properties not changing in value or classification during the intervening year, the value listed on your tax bill received in January is the Assessor's notification of value for the coming year.

The 2008 NOVs for residential properties contain a Comparable Sales Map.  The NOVs are designed to explain the assessment of your property in detail. You can see a sample Notice of Valuation. Your property has been compared to similar homes that sold in the 24 month period from July 1, 2004 to June 30, 2006.

The market comparison grid, photos and market comparison map on the NOV help clarify the assessment process.  The Residential Comparable Sales Map shows your property (blue), and the comparable properties from your NOV (green). 

Our online appeal process is provided for your convenience.  Please review the details of your property as it is described on the NOV.  If corrections are needed we encourage you to contact us.  

We suggest you first read the Letter to property owners about your Notice of Value

You will also need comparable sales to provide evidence that your property value is incorrect.  Here is a link to lists of sales in the proper time frame in your neighborhood:   Comparable Sales Lists
