Assessment Notices & Informal Hearings

The 2025 Revaluation Assessment Notices will be arriving in mailboxes in the coming days.  As you review the change in your properties assessment for the 2025 Grand List it is important to remember the following:

• The notice gives you the prior and new assessment for your property.  This number is 70% of the Fair Market Value per State Statute.  
• This notice is NOT a tax bill and does not reflect what your July 2026 Tax Bill amount will be.  DO NOT use the current mill rate to estimate your taxes.  The mill rate for the July 2026 Tax Bills will not be set until the Town budget process in the Spring of 2026.  
  • Estimating your tax bill with the current mill rate can cause inaccuracies in the understanding of the effect of a revaluation on your tax bill.  Often, when assessments increase the mill rate will decrease.  
• The values on your notice do not reflect any exemptions or credits for which you may qualify, these will be applied by the Assessor’s Office and reflected on your July 2026 Tax Bill.   
• The new values for your property are based on mass appraisal standards and not individual property appraisals. 

Values for the 2025 Revaluation will not be final until AFTER the informal hearing process is complete.   If you have a question or concern about the proposed valuation for your property as indicated on the Assessment Notice, you are strongly encouraged to schedule an informal hearing.  Informal hearings are an opportunity for taxpayers to ask questions about the valuation of their property, explain why they believe the assigned value for their property is incorrect, and review their current property data.  For more information on this process, please see the below video and informational document outlining this process and what can be expected.
