Key Dates for Suffolk County
| Grievance deadline | Suffolk County assessment is administered at the TOWN level: each of the county's ten towns (Babylon, Brookhaven, East Hampton, Huntington, Islip, Riverhead, Shelter Island, Smithtown, Southampton, Southold) has its own elected/appointed assessor and its own three-to-five-member Board of Assessment Review (BAR); there is no single county assessor. A homeowner files Form RP-524 (Complaint on Real Property Assessment) with the assessor of the town where the property is located, on or before Grievance Day. Statewide Grievance Day is normally the fourth Tuesday in May, but New York Tax & Finance lists Suffolk County's Grievance Day as the THIRD Tuesday in May (May 19, 2026). The Town of Brookhaven, a representative Suffolk town, confirms complaints are accepted from May 1 through the third Tuesday in May. Confirm the exact Grievance Day and filing window with the specific town's assessor, as towns may adopt alternate grievance days under RPTL §512. |
