Mass AppraisalAn assessed value is based on the market value of the property. However, municipalities utilize a process commonly known as mass appraisal that values hundreds or thousands of properties at once, not individually. Since the process focuses on multiple properties, their similarities and differences, it is more generalized than a single-property appraisal. The focus of mass appraisal is on the equity of the results.
Informal Assessment Reviews:   (January-early April)The informal assessment review process allows owners to submit documentation to the Assessor for review of their property's assessment. An interior and/or exterior inspection may be requested by you or the Assessor's Office if deemed necessary.

You may submit a request for an informal assessment review for the 2020 Assessment Roll in person or by mail up to April 9, 2021. Forms and instructions are available below. 

Results for the informal reviews:  An Assessment Notice will be mailed the first week of May with the results from the informal hearing (regardless of whether or not a change was made). Any changes made through this informal process will be for the next available Tentative Assessment Roll (filed May 1st) and is not retroactive. If you are not satisfied with the results, you may file a a formal complaint with the Board of Assessment Review. 


Formal Assessment Reviews:    (fourth Tuesday in May, every year)The Tentative Assessment Roll is filed on May 1st each year and marks the beginning of the formal review process.
The Assessor's Office will not accept complaint forms (RP-524) before the May 1st filing of the Tentative Assessment Roll.

HEARING OF ASSESSMENT COMPLAINTS   -   NOTE: This procedure is different for 2020 due to the COVID-19 pandemic - PLEASE READ  (2021 to be determined)

 The Board of Assessment Review is scheduled to meet on Tuesday, May 26th via telephone conference between hours of  4:00 P.M. and 8:00 P.M., to hear and examine all formal complaints in relation to assessments upon the application of any person believing that they have been aggrieved. Since in-person hearings will not be held while social distancing protocols are in effect, it is imperative that a fully completed RP-524 complaint form with all supporting documentation be submitted via mail, email, fax, or Tax Drop Box to the Assessor’s Office before May 26th if possible to afford sufficient time to adequately prepare for the hearings. Once a properly completed complaint form is received, a complainant will be contacted to schedule an appointment for their telephone conference hearing with the Board of Assessment Review. While complaints may be filed until 8:00 P.M. on May 26th, the Board will not hear them until a future date and time. Complainants will be contacted to schedule this appointment.   

 Persons who file a complaint have the option to have the Board review their complaint form without having a telephone conference. The Board will inform them in writing of its decision. Complainants will have opportunity to choose this option when contacted to schedule an appointment.         

 Complaint forms cannot be filed until after May 1st. The complaint form and the publication “Contesting Your Assessment in New York State” are available online at NYS Tax & Finance at or the Assessor’s Home Page at

 Since this a public meeting that the public is allowed to listen to, dial-in instructions for a telephone connection to the meeting will be made available after May 1st on the town’s website or by contacting the Assessor’s Office.

One complaint form must be submitted for each parcel that you are grieving.

COVID-19:  The Assessor's Office is well aware of issues surrounding the COVID-19 pandemic. The 2020 tentative assessment roll is based upon the condition of a property as of March 1, 2020 (taxable status date) and local real estate market conditions as of July 1, 2019 (valuation date). Both legally-prescribed dates predate COVID-19.
