Deadline
Your Grievance Deadline Depends on Where You Live
New York has separate deadlines by locality. In most towns and cities, Grievance Day is the fourth Tuesday in May, but villages, Suffolk County, and Westchester County differ, so confirm the date with your assessor or municipal clerk. New York City sets its own deadlines through the NYC Tax Commission (generally March 1 for Class 2, 3, and 4 and March 15 for Class 1 homes, moved to the next business day when those dates fall on a weekend). Nassau County runs its own window through the Assessment Review Commission, typically January 2 to March 2. Confirm your locality’s exact date before you file.
Start With the Parcel
The local assessment roll is where the assessed value, owner details, and property facts usually begin. Homespring uses the address step to orient the case before asking for more homeowner effort.
Evidence Matters More Than Frustration
A strong grievance usually depends on comparable sales, parcel detail accuracy, and any specific condition issues that affect value.
Local Rules Still Control
Homespring can help homeowners organize the process, but the local roll, the board’s filing steps, and the property’s facts still drive the outcome.
How New York Grievances Work
- Confirm the assessment roll and assessed value for your municipality first.
- Outside New York City, file a Complaint on Real Property Assessment (Form RP-524) with your local Board of Assessment Review on or before Grievance Day.
- In New York City, file with the NYC Tax Commission (Form TC108 for a one- to three-family home); Nassau County owners file with the Assessment Review Commission online.
- If the administrative review does not resolve it, owner-occupied homes can use Small Claims Assessment Review (SCAR), or any owner can bring an Article 7 proceeding in State Supreme Court.

Where to File and Where to Appeal Next
Outside New York City, grievances are filed with the local Board of Assessment Review using Form RP-524. New York City uses the NYC Tax Commission, and Nassau County uses its Assessment Review Commission. If administrative review does not resolve the value, owners of one-, two-, or three-family owner-occupied homes can file Small Claims Assessment Review (SCAR) for a $30 fee, while any owner can pursue an Article 7 tax certiorari proceeding in State Supreme Court. Homeowners can always grieve on their own for free; Homespring is for those who would rather have the comparable sales, evidence, and hearing handled for them.
- New York State Department of Taxation and Finance for statewide grievance procedures, forms, and the SCAR and Article 7 review levels.
- New York City Tax Commission for the separate New York City filing process and deadlines.
