Filing an Appeal

How to File an Appeal with the Board of Equalization

If you choose to appeal the decision of the Assessor's Office regarding your current year actual value or classification determined for your property to the Board of Equalization (BOE), please following the below steps:

  1. Complete and sign the back of the Notice of Determination (NOD). This entire document is the official BOE appeal petition.
  2. Make two copies of the original. Keep one of these copies for your own records.
  3. Mail (certified mail is advised) or drop off the original document, plus one copy (front and back) to:
    Board of Equalization
    4430 S. Adams County Pkwy.
    Fifth Floor, Suite C5000A
    Brighton, CO 80601-8204

Filing Deadlines

Petitions must be postmarked or dropped off by July 15 for real property and by July 20 for business personal property. If the date for filing your petition falls on a Saturday, Sunday or legal holiday, it is deemed to have been timely filed if it is received on the next business day - in accordance with Colorado Revised Statute 39-1-120(3). You may submit your petition as soon as you decide to appeal and submit all or part of your evidence, in duplicate, at a later date.

Items to Include in Your Petition

Please be sure to include the following with your petition. Attach extra sheets, if necessary.

  • A letter of agency signed by you - Required if an agent or attorney is filing the petition for you or you do not plan to be at your hearing, but you do plan to be represented by someone who is not an owner of the property.
  • Any dates and times you are unavailable to attend a hearing - All hearings will be scheduled in mid- to late-July and early August. We will try not to schedule your hearing on a date and time you are unavailable. Due to the volume of appeals and the statutory deadlines, we will not be able to accommodate every request. The earlier we receive your petition, the more likely we will be able to accommodate your schedule. Telephone hearings will not be permitted.
  • Two copies of any evidence supporting your petition - Evidence previously submitted to the Assessor must be resubmitted to the BOE. The BOE is not affiliated with the Assessor's Office.
  • Your estimate of the value of your property
  • Your signature - The petition is not valid without a signature.

Note: Petitions submitted by agents that are not accompanied by valid agency letters will not be accepted.
