[ARCHIVED] County Executive Curran Extends Property Assessment Grievance Period

NASSAU COUNTY, NY – Nassau County Executive Laura Curran announced today that the Assessment Review Commission (ARC) will extend the property assessment grievance deadline from March 1, 2021 to Friday, April 30, 2021 by providing an additional 60-day grace period.


“With many residents still struggling from the devastating repercussions of the COVID-19 pandemic, at my request, ARC Chairperson Robin Laveman has extended the grievance filing period with a 60-day grace period ending on April 30.  This will provide additional breathing room for those who want to fight their property assessment,” said County Executive Curran.   “I will continue to protect the rights of homeowners and do everything I can to ease tax burdens whenever and wherever possible. I encourage homeowners to consider the possible benefits of the grievance procedure.”


Tentative assessed property values for the 2022-2023 assessment roll for every Nassau County property have been finalized and are being mailed out this month.  In addition to being mailed, notices of tentative assessment are also posted online at  


Homeowners who believe that their assessed value for the 2022-2023 assessment roll is inaccurate can file an “Application for Correction of Assessment” with ARC before the close of the grievance filing period, which is extended from March 1 to April 30, 2021.  


Due to the instability of Nassau County’s real estate market caused by the COVID-19 pandemic, and the continued economic hardships homeowners and businesses face, County Executive Curran has paused property valuation updates for the 2022-2023 assessment roll.  Therefore, unless a homeowner has since received a correction of error, an assessment reduction, or physically altered an improvement, their notice of tentative assessment should reflect the same property assessment as the previous assessment roll, which protects against updates based on the current chaotic real estate market.

“Challenging your assessment is a simple process that can be done directly by the property owner in just a few minutes. There are many resources, including a five-minute instructional video, ‘How to Appeal Your Assessment,’ to walk filers through the process.  We are also holding virtual community meetings with the County Legislators to take homeowners through the filing process and to address and answer questions,” said Chairperson Laveman.  


Homeowners can find the calendar of virtual legislative meetings online at and can easily file their grievance on this site.  There is no fee to file an “Application for Correction of Assessment” with Nassau County. For individuals who do not have internet access, the application can be obtained in person at ARC located at 240 Old Country Road in Mineola, or by contacting ARC at (516) 571-3214.  

 The extension of the grievance period will be highlighted on ARC’s website.  Property owners are encouraged to check ARC’s website for up-to-date information.
