New York Property Tax Grievance: Dates by Town, City & NYC

How a New York Assessment Grievance Works

New York calls a challenge to an assessment a grievance. You file Form RP-524 (Complaint on Real Property Assessment) with your local Board of Assessment Review (BAR) on or before Grievance Day. Only the current tentative assessment roll can be grieved, so the tentative roll is the document to look for each spring. The tentative roll date is May 1 in most places.

If you settle by stipulation on or before Grievance Day, that agreement bars any further reduction for the year, so read it before you sign.

When Is Grievance Day?

It depends on where you live. The state's rule and the common local dates:

• Most cities and towns: the fourth Tuesday in May. Cities and towns that share an assessor may pick between the fourth Tuesday in May and the second Tuesday in June.
• Villages that assess: typically the third Tuesday of February.
• Suffolk County town BARs: the third Tuesday in May.
• Westchester County town BARs: the third Tuesday in June.
• Nassau County: March 1.
• New York City (Tax Commission): March 15 for Class One property, which covers one-, two- and three-family homes, and March 1 for all other classes. NY Tax Dept, Grievance Procedure

Grievance dates for the 2026 roll have passed in most places. Look for your tentative roll and your assessor's notice for the next date, because Grievance Day is set locally. The deadlines table and the countdown above the county list show the dates we have confirmed for each New York county.

After the Board Rules: Judicial Review

If the BAR does not give you what you want, you can start a proceeding in court. It must begin within 30 days of the filing of the final assessment roll or the notice of filing, whichever is later. There are two routes: SCAR (Small Claims Assessment Review) and an Article 7 tax certiorari proceeding. SCAR is for owner-occupied one-, two- or three-family homes and vacant land and costs a $30 fee. NY Tax Dept, Grievance Procedure, NY Tax Dept, Contest Your Assessment

STAR and Why It Matters When You Grieve

STAR reduces what you pay, and a lower assessment lowers the base it applies to.

• Basic STAR: income limit of $250,000. The STAR credit limit is $500,000. The exemption applies to the first $30,000 of full value.
• Enhanced STAR: for owners 65 or older with income of $110,750 or less for 2026-27 ($113,550 for 2027-28), applied to the first $88,500 of full value for 2026-27. NY Tax Dept, STAR Types

What Evidence Works

Useful things to gather:

• Recent sales of comparable homes in your neighborhood.
• Your own purchase price and closing statement, if recent.
• Photos and estimates showing condition problems.
• A copy of your property record card, to check square footage and features.
