Generate a New York over-assessed property value challenge demand letter. State-specific deadlines, RPTL grievance rules, and small claims SCAR guidance.
Generate My Letter — $19If you own property in New York and believe your assessment is too high, state law gives you a clear path to fight back. New York's Real Property Tax Law sets out an annual grievance process, followed by judicial review or a streamlined Small Claims Assessment Review (SCAR) for residential owners. Missing a deadline, even by one day, usually ends your appeal for the year. A well-drafted challenge letter to your local Board of Assessment Review (BAR) frames your evidence, preserves your rights, and often resolves the dispute before litigation. This page explains how New York's assessment laws work, what your demand or grievance letter should contain, and what to expect if you must escalate to court or SCAR.
New York taxes real property based on an annual assessment roll prepared by your local assessor. Under RPTL § 305, all real property in an assessing unit must be assessed at a uniform percentage of market value. If your assessment exceeds market value, or exceeds the level applied to comparable properties, you are 'over-assessed' and entitled to relief.
The process begins with the tentative assessment roll, typically filed May 1 (dates vary in cities like New York City, Nassau County, and certain towns). You may file Form RP-524 (Complaint on Real Property Assessment) with the Board of Assessment Review on or before Grievance Day, which is the fourth Tuesday in May in most towns. New York City uses a different system through the Tax Commission with its own March 1 (Class 1) or March 15 (Classes 2-4) deadlines.
Four grounds for challenge are recognized under RPTL § 524: (1) unequal assessment, (2) excessive assessment, (3) unlawful assessment, and (4) misclassification. Most over-valuation cases are filed as 'excessive' or 'unequal.'
If the BAR denies or insufficiently reduces your assessment, RPTL Article 7 allows a tax certiorari proceeding in Supreme Court within 30 days after the final roll is filed (typically July 1). Owner-occupied one-, two-, or three-family residences may instead use SCAR under RPTL § 730, a faster, lower-cost hearing before a court-appointed hearing officer with a $30 filing fee. Evidence typically includes recent comparable sales, an appraisal, photographs of defects, and the municipality's equalization rate. The burden is on the property owner to show the assessment is excessive by substantial evidence.
A New York over-assessment challenge letter serves two purposes: it accompanies your formal RP-524 grievance, and it can also be sent informally to the assessor before Grievance Day to invite an early stipulated reduction. Many assessors will adjust assessments without a hearing if presented with credible evidence.
Your letter should identify the property by tax map number and address, state the current assessed value and your proposed value, and specify the legal ground (excessive or unequal assessment under RPTL § 524). Attach your evidence: three to five recent arm's-length comparable sales, the municipality's residential assessment ratio (RAR) or equalization rate published by the NYS Department of Taxation and Finance, a licensed appraisal if available, and documentation of any condition issues, easements, or zoning limits that reduce value.
Calculate the requested reduction. For an unequal claim, multiply market value by the RAR to arrive at the legally correct assessment. For an excessive claim, simply demonstrate market value is below the assessment.
Close the letter by demanding a specific reduction, requesting a stipulation before Grievance Day, and reserving your right to proceed to BAR, SCAR, or Article 7 review. Send by certified mail or hand-deliver and keep a date-stamped copy. A clear, evidence-based letter signals to the assessor that you are prepared to litigate, which often produces a settlement at or below the cost of a contested hearing.
Article 7 petitions are filed in Supreme Court in the county where the property is located; filing fees are typically $210. SCAR petitions cost $30 and are limited to owner-occupied one-, two-, or three-family residences. The small claims monetary framing differs from general civil court—SCAR has no fixed dollar cap on the assessment but is limited to residential property and one tax year per petition. New York City uses the NYC Tax Commission (Form TC101/TC108/TC109) with deadlines of March 1 or March 15 depending on tax class. Nassau County uses the Assessment Review Commission with its own March 1 deadline. Always confirm local Grievance Day and final roll dates with your assessor, as they vary by jurisdiction.
Property tax in New York is governed by the New York Real Property Tax Law (RPTL); assessment review under Article 5, judicial review under Article 7, enforcement under Article 11 (N.Y. Real Property Tax Law (RPTL) §§ 512, 524, 525 (BAR review); Article 7 (judicial review); Article 11 (enforcement)). Assessment cycle: Annual assessment roll. Assessor files a tentative assessment roll (typically May 1 in most towns), followed by Grievance Day, then a final roll (typically July 1). Property is assessed at a locally-determined uniform percentage of market value; NYC and Nassau County operate on their own class-based cycles. Assessed value: No single statewide ratio — each municipality assesses at a locally-determined uniform percentage of market value (the 'level of assessment'). ORPTS establishes an annual equalization rate / residential assessment ratio (RAR) for each municipality, used to prove unequal assessment. NYC uses a class-based system with statutory assessment percentages per tax class.
New York State Department of Taxation and Finance, Office of Real Property Tax Services (ORPTS) — oversight, equalization rates, STAR administration, and forms; assessments administered locally by municipal assessors and Boards of Assessment Review, with judicial review in the state Supreme Court. NYC assessments are administered by the NYC Department of Finance. The window to act is short — complaint (Form RP-524) must be filed with the assessor or Board of Assessment Review (BAR) on or before Grievance Day. Under RPTL § 512 the default Grievance Day is the fourth Tuesday of May (May 26, 2026), but many municipalities adopt alternate dates by local law, so confirm the local date. SCAR/Article 7 petitions must be filed within 30 days after the final roll is filed.
A recent change to watch: 2025 real property tax legislation authorizes ORPTS-driven automatic upgrade of qualifying Basic STAR recipients to Enhanced STAR without a new application, with most changes taking effect in 2026. Effective December 2025, Cold War veterans became eligible to apply for the Alternative Veterans Exemption.
How your value is assessed: No single statewide ratio — each municipality assesses at a locally-determined uniform percentage of market value (the 'level of assessment'). ORPTS establishes an annual equalization rate / residential assessment ratio (RAR) for each municipality, used to prove unequal assessment. NYC uses a class-based system with statutory assessment percentages per tax class.
Evidence that works: Recent comparable sales, appraisals, the property's purchase price, the municipal equalization rate / residential assessment ratio (to prove unequal assessment), income/expense data for income-producing property, and condition evidence. Article 7 proceedings typically require USPAP-compliant certified appraisals. Complaint must be on Form RP-524.
Appeal deadline: Complaint (Form RP-524) must be filed with the assessor or Board of Assessment Review (BAR) on or before Grievance Day. Under RPTL § 512 the default Grievance Day is the fourth Tuesday of May (May 26, 2026), but many municipalities adopt alternate dates by local law, so confirm the local date. SCAR/Article 7 petitions must be filed within 30 days after the final roll is filed.
First-level appeal: Board of Assessment Review (BAR) — file Form RP-524 by Grievance Day; the BAR convenes to hear and determine complaints and mails a notice of determination (RPTL §§ 524-525).
Next-level appeal: After a BAR determination, two judicial paths: (1) Small Claims Assessment Review (SCAR) — low-cost ($30 filing fee), no attorney required, informal, limited to owner-occupied 1-3 family residences; or (2) Tax Certiorari under RPTL Article 7 in Supreme Court — formal, for commercial/multi-unit/higher-value property. Both must be filed within 30 days of the final assessment roll.
Grounds you can raise: Four statutory grounds under RPTL § 524: (1) excessive assessment (overvaluation, or improper denial/reduction of an exemption); (2) unequal assessment (higher percentage of market value than other property); (3) unlawful assessment; and (4) misclassification.
Exemptions to claim: STAR / School Tax Relief (Basic STAR; Enhanced STAR for seniors 65+ with limited income, RPTL § 425, now delivered largely as a credit/check for newer applicants); Senior Citizens 'Aged' exemption (RPTL § 467, income-limited); Persons with Disabilities exemption (§ 459-c); Veterans exemptions — Alternative (§ 458-a), Eligible Funds (§ 458), and Cold War (§ 458-b); agricultural, religious, and charitable exemptions. Most require a one-time application; some (e.g., Aged) require annual income recertification.
The hearing: BAR: informal in-person hearing (Grievance Day) with sworn statements. SCAR: informal hearing before a court-appointed hearing officer, no attorney needed, relaxed rules of evidence. Article 7: formal Supreme Court litigation with pleadings, appraisals, and trial.
First, board of Assessment Review (BAR) — file Form RP-524 by Grievance Day; the BAR convenes to hear and determine complaints and mails a notice of determination (RPTL §§ 524-525).
If that fails, after a BAR determination, two judicial paths: (1) Small Claims Assessment Review (SCAR) — low-cost ($30 filing fee), no attorney required, informal, limited to owner-occupied 1-3 family residences; or (2) Tax Certiorari under RPTL Article 7 in Supreme Court — formal, for commercial/multi-unit/higher-value property. Both must be filed within 30 days of the final assessment roll.
Mind the deadline: complaint (Form RP-524) must be filed with the assessor or Board of Assessment Review (BAR) on or before Grievance Day. Under RPTL § 512 the default Grievance Day is the fourth Tuesday of May (May 26, 2026), but many municipalities adopt alternate dates by local law, so confirm the local date. SCAR/Article 7 petitions must be filed within 30 days after the final roll is filed.
