Board of Equalization (BOE)

The BOE is not affiliated with the Assessor’s Office. Please contact the Assessor’s Office at (303) 441-3530, or, for questions regarding your Notice of Determination or the valuation of your property.

About the BOE

The BOE’s mission is to assure just and equalized property tax assessments and to ensure taxpayers have full access to the appeal system. The Boulder County Board of Commissioners sits as the Board of Equalization. Statutory time limits of the appeal period do not permit the Commissioners to attend hearings. They appoint highly qualified hearing officers to preside at the hearings and to make recommendations to the BOE.

Who can appeal to the BOE?

Property owners may appeal the Assessor’s office Notice of Determination concerning the value of their property for the current year to the BOE. The BOE determines the value of property in Boulder County, when there is a question or dispute that is not resolved with an appeal at the Assessor level, by holding hearings during September and October, all such hearings shall be concluded and decisions rendered thereon by November 1st.

  • A property owner must have appealed at the Assessor level and received a Notice of Determination in order to proceed with an appeal to the BOE.
  • The Assessor’s office will mail Notices of Determination (NOD) in mid August. A property owner may appeal to the BOE as soon as they receive their NOD through the deadline of September 15th.*

The BOE is not affiliated with the Assessor’s Office. Please contact the Assessor’s office at (303) 441-3530, or email, for questions regarding your Notice of Determination or the valuation of your property.

Important information for petitioners:

  • All BOE hearings will be held remotely via Microsoft Teams video or phone call.
  • The Assessor’s representative and the Petitioner will each receive equal time to present their case at the hearing. The Hearing Officer will take into consideration information provided by the parties to make a recommendation.

Per statute, the Assessor’s office has compared your property to similar homes that sold in the 24 month period from July 1, 2020 to June 30, 2022. The BOE considers comparables within that statutory timeframe.
    • If you have additional evidence which was not submitted with the original appeal, you must email that additional evidence to the BOE no later than three business (3) days before your scheduled hearing. (
    • Consider the time constraint for your hearing. Please choose evidence thoughtfully and which supports your requested value.
    • The BOE is not affiliated with the Assessor’s office. Any evidence you submitted to the Assessor’s Office for appeal will not be provided to the BOE.

When will I receive notice of my hearing?

Notices of Hearing are sent via U.S. Mail. If you include your email address on your petition, the notice will be emailed to you. Due to the short window of time allowed for BOE hearings by legislation, there may be little notice prior to a hearing date, and the BOE cannot reschedule hearings. If your hearing has been scheduled, you can use the BOE Hearing Schedule search at right. Your account will not show up if your hearing has not been scheduled.

What if I cannot attend my hearing?

If you are unable to attend the hearing, the hearing will be held in your absence and your evidence will be considered in the Hearing Officer’s recommendation.
