If you own a home in Suffolk County, your property is almost certainly assessed at a value that hasn't been updated in years — possibly decades. Suffolk County is the only county in the United States that does not reassess properties on a regular basis. That means the only way to reduce your tax bill is to file a property tax grievance.
The process in Suffolk is more involved than Nassau — it has two stages, 10 separate town boards, and most first-stage filings are denied. But that's normal, expected, and not a reason to give up. The second stage — SCAR — is where the reductions are actually won. This guide explains exactly how it works.
The deadline to file your BAR grievance with your Suffolk town is May 19, 2026 — the third Tuesday in May, for all 10 Suffolk towns. This is a firm deadline. Missing it means waiting until May 2027.
What makes Suffolk County different from Nassau
Nassau County has one centralized Assessment Review Commission (ARC) that handles all homeowners countywide. Suffolk County works completely differently — and it's important to understand why before you file.
In Suffolk, each of the 10 towns handles its own property assessments and grievance process independently:
Your grievance must be filed with the correct town's Board of Assessment Review (BAR) — not a county office. GrieveItNow knows the requirements for each of the 10 Suffolk towns and files in the right place with the right documentation every time.
Suffolk County is the only county in the United States that does not reassess on a regular basis. Many Suffolk properties haven't had an updated assessment in 10, 20, or even 30 years. This means assessments are frequently and significantly out of line with actual market values — which is exactly why grievances succeed.
The two-stage Suffolk grievance process
Suffolk County grievances have two stages. Most homeowners — and even many competitors — don't fully explain what that means. Here's the honest picture:
The reason most competitors don't explain this clearly is that the two-stage process is what justifies their 50% contingency fee. At GrieveItNow, both stages — BAR and SCAR — are included in our $199 flat fee. The $30 SCAR court filing fee is also included.
Under New York State law, your assessment cannot be increased as a result of filing a grievance. The two possible outcomes are: your assessment is reduced, or it stays the same. A BAR denial is not a penalty — it's simply the first step in a two-step process.
The 3-year lock — Suffolk's biggest advantage
A winning SCAR locks your assessment for 3 years
In Suffolk County, a successful SCAR reduction carries forward automatically to the next three tax years. One filing. Three years of lower taxes. No re-filing required during the lock period. This is unique to Suffolk and makes a successful grievance significantly more valuable than in Nassau.
What happens after you file — the full timeline
Now through May 19, 2026 — File your BAR grievance
Form RP-524 (Complaint on Real Property Assessment) is filed with your specific town's Board of Assessment Review. GrieveItNow prepares and submits your RP-524 with comparable sales evidence before the May 19 deadline.
May – August 2026 — BAR reviews and likely denies
Your town BAR has 30–60 days to review thousands of filings. The vast majority are denied — not because cases aren't valid, but because the BAR simply doesn't have the time or resources to grant reductions at the first stage. A denial is expected. It is not the end of your case.
July – September 2026 — SCAR petition filed
After a BAR denial, GrieveItNow files your SCAR petition in New York State Supreme Court. The $30 SCAR filing fee is included in your $199. Most towns seek a settlement conference before the formal hearing — this is where the negotiation happens.
2026–2027 — SCAR hearing and settlement
SCAR hearings are informal proceedings before a hearing officer. Most cases settle through negotiation before the hearing date. The SCAR process typically takes 12–24 months from filing to resolution. GrieveItNow handles all communication, evidence preparation, and negotiation on your behalf.
Upon resolution — savings and 3-year lock
Once your assessment is reduced through SCAR, you're entitled to a refund for any overpaid taxes in the current year. Your lower assessment is then locked for the following three tax years automatically — no re-filing required during that period.

File Before May 19 →Should you file yourself or hire someone?
You can file a BAR grievance yourself by submitting Form RP-524 to your town assessor's office before May 19. The form is available on your town's website and there's no filing fee at the BAR stage.
The challenge in Suffolk is the two-stage nature of the process. Filing the BAR correctly is straightforward — but handling the SCAR petition, preparing evidence for a court proceeding, and negotiating with the town attorney requires more expertise. Most homeowners who file their own BAR grievance don't follow through to SCAR, which means they walk away with nothing even when they had a valid case.
The fee model question — what you're really paying
Most Suffolk County grievance firms charge 50% of your first year's savings if they win. On a $2,000 annual reduction, that's $1,000 taken from your pocket — and they take it again every cycle. Some firms also add a $75 appraisal fee on top of that.

GrieveItNow was built by Chris and Stephen A., two Long Island brothers. Stephen filed his own grievance in Northport and saved over $700 a year. Their parents in Great Neck received a reduction after years of overpaying. They built GrieveItNow because Long Island homeowners shouldn't have to hand over half their savings just to get fair representation.
