Property owners who disagree with the Assessor’s Notice of Determination can appeal that decision to the Board of Equalization (BOE). The Boulder County Board of Commissioners (BOCC) sits as the Board of Equalization. The mission of the BOE is to assure just and equalized property tax assessments and to ensure taxpayers have full access to the appeal system.
To appeal your property’s valuation, follow the instructions provided below. The deadline to submit an appeal is Sept. 15.
How do I file an appeal?
- Complete and sign the back of the Notice of Determination. Submit all documents and evidence in duplicate by Sept. 15 and keep a copy for your records (you will need three copies total of each document)
- Include the following with your petition (attach extra sheets if necessary):
- Your estimate of the value of your property.
- Any evidence you submitted to the Assessor for your initial protest that you wish to use again in your appeal to the BOE. The BOE is not affiliated with the Assessor’s office. Any evidence you submitted to the Assessor for your initial protest will not be shared with the BOE unless you submit it.
- A letter of agency signed by you, if:
- An agent is filing the Petition for you -OR-
- You do not plan to be present at your hearing but will be represented by someone who is not an attorney at law licensed in the State of Colorado.
Mail or deliver your petition to a BOE agent by Sept. 15. Mailed petitions must be postmarked by Sept. 15. Certified mail is recommended. You may submit your petition as soon as you decide to appeal and submit all or portions of your evidence, in duplicate, at any time-up to and including at your hearing.
