When and how do I grieve my Suffolk County property assessment?
Suffolk County is assessed by its ten towns, each with its own Board of Assessment Review; Grievance Day there is the third Tuesday in May, and you file Form RP-524 with your town assessor.
Unlike Nassau County (which assesses county-wide through ARC), Suffolk County is assessed at the town level — each of its ten towns (Babylon, Brookhaven, East Hampton, Huntington, Islip, Riverhead, Shelter Island, Smithtown, Southampton, Southold) maintains its own assessment roll and Board of Assessment Review (BAR).
The deadline. In the Suffolk towns, Grievance Day is the third Tuesday in May — one week earlier than the statewide fourth-Tuesday default. Confirm the exact date and any town-specific instructions with your town assessor before filing.
How to file. Use the standard Form RP-524, Complaint on Real Property Assessment, filed with your town assessor or the BAR on or before Grievance Day. Follow the same statewide grievance procedures: state the ground (excessive, unequal, unlawful, or misclassified per RPTL §524), your claimed value, and the reduction sought.
Evidence. Because Suffolk towns assess at a fractional level, an unequal assessment claim using the residential assessment ratio (RAR) is often the strongest argument, alongside comparable sales of similar nearby homes.
If the town BAR denies you. As an owner-occupant of a 1-3 family home you can file a SCAR petition under RPTL §730 — a $30 fee, filed within 30 days of the town's final assessment roll. You must have grieved to the BAR first.
Note each town runs its own calendar and roll dates, so verify your specific town's Grievance Day, final-roll date, and any village grievance dates separately if your home sits within an incorporated village that assesses on its own.
