The Westchester process
Your town or city sets the value, and sets the calendar
Westchester County does not assess homes. Each town and city has its own assessor and its own Board of Assessment Review, and a few villages keep a separate roll too. Most towns publish the tentative roll around June 1 and take grievances until Grievance Day, the third Tuesday in June. Yonkers takes them November 1 to 15, and White Plains January 1 to 21.
02
Build the evidence
We compare recent sales of similar nearby homes and document condition problems that the assessment 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 or city on time and handle the Board of Assessment Review hearing.
A complete case, not a generic form
What makes a Westchester grievance persuasive
Many Westchester rolls assess homes at a small fraction of market value. That fraction is called the level of assessment, and the state publishes it as the equalization rate. Divide your assessed value by it to find the market value the assessor is using. In Yonkers the 2026 rate was 1.41%, so a $10,000 assessment stands for about $709,000. If your home would sell for less, you may be over-assessed.

Recent sales of similar homes nearby, close to the valuation date, that sold for less than the market value your assessor assigned to yours.
Property-record accuracy
Square footage, bedrooms, baths, finished space, lot and other details on the town or city record that may overstate value.
Condition and location
Dated photos and repair estimates for problems like an aging roof or a wet basement, plus traffic, steep lots or other factors that lower price.
A specific requested value
A clear market value the sales support, converted back 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.”

Westchester County property tax grievance questions
Who assesses my home, the county, my town, my city or my village?
Not the county. Your town or city assessor sets the value, and its Board of Assessment Review hears grievances. Yonkers, White Plains, New Rochelle and Mount Vernon each run their own process. A few villages 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 Westchester grievance deadline?
It depends on where you live. Most towns take grievances until the third Tuesday in June. The 2026 date has passed, so the next is June 15, 2027. Yonkers is open November 1 to 15. Because November 15, 2026 is a Sunday, the city's weekend rule moves it to Monday, November 16, by 8 p.m. White Plains takes complaints January 1 to 21, 2027. Other cities set their own dates, so confirm yours on your notice or with your assessor.
I live in Yonkers. What is different there?
The form must be in the Assessment Department by 8 p.m. on the deadline. Last year the city took filings in person only and did not accept postmarks. Owners also sign a residential questionnaire, and any added information is due December 15. Hearings run from late January into February, and decisions are mailed on or soon after April 10. The September 15 informal review date has passed for this year.
Can I file a Westchester 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, dated in the same year the complaint is filed.
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 mails a written decision. If you disagree, owner-occupants of one, two or three family homes can file for Small Claims Assessment Review (SCAR) with the Westchester County Clerk on their own. It costs $30 and is due within 30 days after the final roll is filed. Homespring's service covers the local grievance, not SCAR.
Check the home before your local deadline
Start with the address. Homespring will check your town or city record and whether the home should move into a grievance review. An address check does not file an appeal. Availability depends on your property and filing year.
