East Hampton homeowners — from Springs to Amagansett to Montauk — face some of the most complex property assessments in New York. The BAR deadline is May 19, 2026. Filing is risk-free and costs nothing if there's no reduction.
The Town of East Hampton encompasses some of the most valuable real estate on Long Island — from the celebrity estates of East Hampton village and Amagansett to the working waterfront of Montauk and the year-round residential neighborhoods of Springs and Northwest Harbor. While the high-end market receives the most attention, it is often the year-round resident — not the seasonal homeowner — who bears a disproportionate assessment burden. Properties that have appreciated dramatically relative to their assessment base, or that sit between wildly different market segments, are frequently over-assessed.
According to the New York State 2026 Property Assessment Data, the Residential Assessment Ratio (RAR) for the Town of East Hampton is 0.30% — the lowest RAR of any of the ten Suffolk towns, reflecting the town's extremely high market values. To calculate what the assessor implies your home is worth, divide your assessed value by 0.0030. If that implied value exceeds recent comparable sales in your area, you are over-assessed. GrieveItNow handles the complete East Hampton BAR and SCAR process for a flat $199 fee, including the $30 SCAR court filing fee.
Example: If your East Hampton assessed value is $3,000, the assessor's implied market value is $3,000 ÷ 0.0030 = $1,000,000. If comparable homes in your neighborhood sold for less, you have a strong case. Source: NYS Office of Real Property Tax Services, PAD file 2026.
BAR filing deadline: May 19, 2026 — Form RP-524 must be received by the Town of East Hampton assessor's office by that date.
SCAR deadline: July 2026 — SCAR petitions for East Hampton are filed with the Suffolk County Clerk after the BAR denial. GrieveItNow tracks and manages both deadlines automatically.
East Hampton's extremely low RAR of 0.30% reflects the fact that properties here carry some of the highest market values in New York State. But low RAR also means small assessment errors translate to massive dollar differences in implied market value — making the unequal assessment argument particularly powerful for East Hampton homeowners. Two nearly identical homes in Springs can have very different assessments simply because no systematic reassessment has been conducted in decades.
Year-round residents in Springs, Northwest Harbor, and the less-publicized parts of the town frequently find their assessments out of line with neighbors in comparable properties. The seasonal nature of East Hampton's market further distorts the picture — sales prices for summer-focused properties don't always reflect the value of a year-round home. A grievance based on careful comparable analysis, anchored to the 0.30% RAR, is the most effective tool available to correct this.
Suffolk County is the only county in the United States that does not reassess property on a regular basis. The only way to lower your East Hampton property tax bill is to file a grievance. If you don't file, your over-assessment stays in place indefinitely.
You file Form RP-524 with the Town of East Hampton assessor's office before May 19, 2026. The BAR reviews your complaint, comparable sales evidence, and RAR-based valuation analysis. In most East Hampton cases, the BAR issues a denial. This is the expected and normal first step — not a final outcome. A denial at the BAR stage simply advances the case to SCAR, where the real reductions happen.
After a BAR denial, GrieveItNow files your SCAR petition with the Suffolk County Clerk's Office in July 2026. SCAR is a New York State Supreme Court proceeding conducted informally before a hearing officer. The vast majority of East Hampton SCAR cases resolve through negotiated settlement before any formal hearing. A successful SCAR reduction locks your lower assessment for the next three tax years. GrieveItNow includes the $30 SCAR court filing fee in the $199 flat fee — no surprise charges.
New York State law prohibits your East Hampton assessment from being increased as a result of filing a grievance. The only two outcomes are a reduction or no change. If there is no reduction, GrieveItNow refunds your full $199 fee. No reduction, no charge — ever.
All communities within the Town of East Hampton — including East Hampton village, Springs, Amagansett, Montauk, Wainscott, and Northwest Harbor — share the same May 19, 2026 BAR deadline and file with the same Town of East Hampton assessor's office. GrieveItNow files for every East Hampton community regardless of neighborhood or school district.
The two most common and most successful grievance arguments in East Hampton are unequal assessment — where your home is taxed at a higher effective rate than comparable nearby properties — and excessive assessment — where the assessed value is higher than current market value based on recent comparable sales. GrieveItNow builds the strongest possible case for each client using current arms-length sale data calibrated to East Hampton's 0.30% RAR.
BAR + SCAR + $30 court fee — all included for $199 flat. No reduction means every dollar back.
