A Boulder BOE appeal follows the Assessor determination

A value appeal does not end when the Assessor rules against you. If you still disagree with the determination, you can take it one level higher by filing a written appeal to the Board of Equalization before the county deadline. The first round is a conversation with the office that set the value; the second puts your case before a separate board.

Two small things make that second appeal go smoothly. Start from the Notice of Determination — the account number printed on it is what ties your petition to the right property. Then state plainly what value you believe is correct and back it with evidence: comparable sales, photos of condition, a recent appraisal, anything that speaks to what the home is worth.

This is the part people get wrong. The Board of Equalization weighs value, not grievance. A petition built on frustration with the size of the final tax bill has nothing for the board to grab onto, because the bill is a product of value and mill levies the board cannot rewrite. A petition built on three solid comparable sales gives them a reason to move your number.

The clock is the real constraint. Both the Assessor’s appeals page and the Board of Equalization page lay out the steps, but neither extends the deadline, so read them while there is still room to gather evidence rather than the night before. Keep the Notice of Determination within reach the whole way through; it is the thread that connects one stage to the next.
