Open Book and Board of Review
What is Open Book?
Open book is the period of time where you may meet with the town’s contracted assessor to examine your property tax assessment and discuss how they arrived at your assessed value.
If you wish to dispute your property tax assessment you must attend the Board of Review.
What is the Board of Review?
Ordinarily, the Board of Review consists of municipal officials and functions like a quasi-jurisdictional court in that it hears evidence that is presented. The municipal clerk also functions as the Board of Review clerk. The Board of Review has the duty of correcting any errors in assessment that have been made, inadvertently or otherwise. It is the duty of the Board of Review to carefully examine the roll and correct all apparent errors in descriptions or computations, and to add any property to the roll that the assessor may have omitted. However, the Board of Review must notify the property owners concerned and hold hearings before omitted property can be added to the assessment roll and before any other lawful changes can be made.
Once the assessor has valued the property, posted these values on the assessment roll, and signed the affidavit attached to the assessment roll, the values must be accepted as correct unless the testimony of sworn witnesses and the evidence they present indicate otherwise.
The Board of Review is responsible for raising and lowering any incorrect valuations as well as correcting any errors in the roll. It is important to note that the Board’s function is not one of valuation, but of deciding the validity of the facts presented, under oath, before it. All deliberations must be done in open session and the Board of Review is required to decide each objection by a roll call vote. If the Board of Review votes to change an assessment, it must state on the record the amount of the correct assessment and that the correct assessment is reasonable in light of all relevant evidence received. Notices of the Board’s determinations are to be sent to property owners as the Board completes its work.
Manufacturing assessments are reviewed by the Tax Appeals Commission, rather than the local Board of Review.
