How grievances work in Suffolk

Your town assesses your home, not the county.Each of Suffolk's 10 towns, from Babylon and Brookhaven to Southold, has its own assessor and its own Board of Assessment Review.
The window is in May.Towns file their tentative rolls on May 1, and grievances are due on Grievance Day, the third Tuesday in May (May 18, 2027). Some villages that assess separately use earlier dates.
It's free and paper-based.You file form RP-524 with your town's assessor, with sales of similar homes as evidence. Filing can't raise your assessment.

We'll have a Suffolk guide and value check ready before May 1. Leave your email above and we'll send one note when it's live.
