The Suffolk County process
Your town sets the value, and the window is short
Suffolk County has no county assessor. Each of the ten towns assesses homes and has its own Board of Assessment Review. Towns publish the tentative roll around May 1, and the grievance must reach the town by Grievance Day, the third Tuesday in May. The 2026 date has passed, so the next one is May 18, 2027, about two and a half weeks after the roll comes out.
02
Build the evidence
We compare recent sales of similar nearby homes and document condition problems that the town's value does not reflect.
03
File and represent
You sign Part Four of Form RP-524 naming us as your representative. We file the complaint with your town by Grievance Day and handle the Board of Assessment Review hearing.
A complete case, not a generic form
What makes a Suffolk grievance persuasive
Most Suffolk towns assess at a small fraction of market value, called the level of assessment. The state's version of that figure is the equalization rate, and for homes there is also a residential assessment ratio. Divide your assessed value by that percentage to find the full market value your town is using. If that is more than your home would sell for, you may be over-assessed.

Property-record accuracy
Square footage, bedrooms, baths, finished space, lot and other details on the town record that may overstate value.
Condition and location
Dated photos and repair estimates for problems like an aging roof or water damage, plus traffic, flood exposure or other factors that lower price.
A specific requested value
A clear market value the sales support, converted into the assessment you ask for. The board may not grant more than you request, so the number matters.

“The overall experience was strong. I had one minor delay getting a document together on my side, but once it was uploaded everything moved along smoothly.”

“The platform was clear and the process felt dependable. We did not end up with a dramatic dollar result, but I still felt the work was handled professionally from beginning to end.”

“My biggest concern was whether this would turn into another half-finished online form. It did not. The follow-through was consistent and the end result was better than I expected.”

Suffolk County property tax grievance questions
Who assesses my home, the county, my town or my village?
Your town. Babylon, Brookhaven, East Hampton, Huntington, Islip, Riverhead, Shelter Island, Smithtown, Southampton and Southold each set values and run their own Board of Assessment Review. Some villages, such as Lindenhurst, also assess. A home in one of those villages has two assessments, and each needs its own Form RP-524 by its own deadline.
When is the next Suffolk County grievance deadline?
Town grievances are due on Grievance Day, the third Tuesday in May. The 2026 date has passed, so the next is May 18, 2027. Towns publish the tentative roll around May 1, and the form must be received by Grievance Day, not just mailed. Missing it ends your chance to challenge that year's assessment.
I live in Lindenhurst village. Is there a fall deadline?
Yes, for the village assessment only. The Village of Lindenhurst grievance period runs from November 1 to the third Tuesday in November, which is November 17, 2026. Confirm the office cutoff time with the village. Your Town of Babylon grievance is separate and due in May.
Can I file a Suffolk grievance myself?
Yes. There is no cost to grieve and you do not need a lawyer. Homespring is for homeowners who want the research, filing and hearing handled. To have anyone act for you, you sign Part Four of Form RP-524, the designation of representative.
How does Homespring charge?
There is no upfront fee. If Homespring lowers your property taxes, the fee is 25% of the first year's tax savings. If there are no savings, there is no fee.
What if the board does not lower my assessment?
The board sends a written decision with its reasons. If you disagree, owner-occupants of one, two or three family homes can ask a court for Small Claims Assessment Review (SCAR) on their own. It costs $30 and is generally due within 30 days after the final roll is filed. Homespring's service covers the town grievance, not SCAR.
