How to Lower Property Taxes in New York
New York's property tax system is fragmented by design — rules, deadlines, and appeal bodies differ by municipality, meaning a homeowner in Buffalo follows a different process than one in Westchester or Queens. What stays constant: every property owner has the right to challenge an over-assessment, and you can do it yourself without hiring anyone. This guide walks you through how.
Is Your New York Assessment Too High?
Your property tax bill depends on your assessed value and the local tax rate (expressed as a mill rate). In New York, most localities assess at a fraction of full market value — called the level of assessment or assessment ratio. If the implied market value from your assessed value is higher than what comparable homes in your area have actually sold for, that gap is your grounds for an appeal.
Start with your property record card, available through your local assessor's office or online portal. Check every detail: square footage, bedroom and bathroom count, lot size, year built, and any listed improvements. Mass-appraisal data contains errors — a garage listed as finished living space or an extra bathroom that doesn't exist can meaningfully inflate your value.
New York's Appeal Process: Grievance Day and Beyond
New York municipalities set assessed values annually. The formal challenge process has two main stages.
Step 1 — File a Grievance with Your Local Board of Assessment Review
Every municipality holds a Grievance Day — typically in May for most towns and cities, though the exact date varies. You file a complaint form (RP-524 in most jurisdictions) with your local Board of Assessment Review before that date. The board reviews your evidence and issues a written determination. This step is free and required before you can escalate further.
Confirm your municipality's Grievance Day date directly with your local assessor — missing it means waiting a full year. Do not rely on any date you read online, including here.
Step 2 — Escalate to Small Claims Assessment Review/SCAR or Supreme Court
If the Board of Assessment Review denies your grievance or doesn't reduce the value enough, residential property owners can file a Small Claims Assessment Review/SCAR petition with the New York Supreme Court. The filing fee is modest, hearings are informal, and no attorney is required — a hearing officer issues a binding decision. NYC residents follow a separate path through the NYC Tax Commission, with further appeals to the Tax Appeals Tribunal or Supreme Court.
What Evidence Works in New York
Both the Board of Assessment Review and SCAR respond to comparable sales — recent arm's-length sales of properties similar to yours in size, age, condition, and location. Three to five solid comps from the prior year, pulled from public deed records or your county's property search portal, are usually enough to make your case.
Supporting materials that strengthen your argument:
- Your annotated property record card noting any factual errors
- Photos of deferred maintenance or condition issues the assessor's data doesn't reflect
- A recent independent appraisal (carries the most weight at SCAR)
- A simple one-page grid: each comp's address, sale date, price, square footage, and price per square foot
Keep it concise. Hearing officers and board members read many cases — a clear, organized packet of five comps beats a thick binder of loosely related documents.
Exemptions That Lower Your Bill Without an Appeal
An appeal targets your assessed value. Exemptions reduce the taxable portion directly, with no hearing required. New York offers the Basic STAR exemption (Enhanced STAR for homeowners 65+), a veterans' exemption, and exemptions for persons with disabilities or limited income. If you qualify for STAR and haven't registered, that step alone may cut your school tax bill noticeably. Apply through your local assessor's office — deadlines vary by municipality.
DIY vs. Hiring a Tax Reduction Firm
Property tax reduction firms in the New York suburbs typically work on contingency, taking a share of first-year savings if they win. For a straightforward overvaluation with solid comparable sales, the DIY path through Grievance Day and SCAR is very achievable — forms are standard and hearings informal. Professional help makes more sense for high-value properties, complex assessments, or if you prefer not to present your own case. No reduction is guaranteed either way.
In New York the Hardest Part of an Appeal Is Finding Your Deadline
New York's effective rate is 1.60%, rank 6 of 51 states and the District of Columbia, with a median bill of $6,450 on a median home value of $403,000 — among the highest in the country on both measures. The procedure, however, is where owners lose their cases, and usually before any evidence is considered. There is no single statewide filing date.
| Where the property is | Deadline | Note |
|---|---|---|
| Most towns and cities | Fourth Tuesday in May | Grievance Day; Form RP-524 must be received by then |
| New York City | March 15 for Class One, March 1 for all others | Commission meets throughout the year |
| Nassau County | March 1 | Commission meets throughout the year |
| Suffolk County | Third Tuesday in May | Town boards of assessment review |
| Westchester County | Third Tuesday in June | Town boards of assessment review |
| Villages that assess | Typically third Tuesday in February | Dates vary — confirm with the village |
| Cities and towns sharing an assessor | Between the fourth Tuesday in May and the second Tuesday in June | May adopt their own date |
Seven different answers in one state. Grievance Day is the deadline for filing Form RP-524 and also the day the board of assessment review meets to hear complaints. If you post the form it has to be received by then, not merely postmarked. Confirm the date with your own assessor every year — a date that was right last year may not be right this year, particularly where municipalities share an assessor.
Two Stages: The Board First, Then the Courts
Administrative review comes first and you cannot skip it. You file Form RP-524 with the assessor or the board of assessment review. Before Grievance Day you and the assessor may stipulate to a reduced assessment — but if you accept a stipulation you give up asking the board for a further reduction, so judge the offer against what your evidence supports.
If the board's decision does not resolve it, two judicial routes follow:
| Route | Who can use it | Cost |
|---|---|---|
| Small Claims Assessment Review (SCAR) | Owners living in their own one, two or three family home used exclusively for residential purposes; owners of vacant land too small for such a dwelling | $30 filing fee |
| Tax certiorari, Supreme Court | Any property, under Article 7 of the Real Property Tax Law | Counsel strongly recommended |
The judicial deadline is short and separate. SCAR and tax certiorari proceedings must be started within 30 days of the filing of the final assessment roll, or of notice of that filing, whichever is later. That is a different clock from Grievance Day, and it starts after the board has ruled. At $30, SCAR is the route built for homeowners — it exists precisely so that a modest dispute does not require a lawyer.
Non-resident owners have an extra right worth using: a written request, made no later than 15 days before the tentative roll date (May 1 in most communities), obliges the assessor to send you your property's assessed value and the time and place of grievance hearings within five days of the roll being completed.
Median Tax by New York County
The eight counties with the highest median bills, of 62. Several reach the Census ceiling, so their true medians are higher than shown.
| County | Median tax paid | Median home value | Effective rate |
|---|---|---|---|
| Nassau | $10,001+ | $658,700 | 1.52% |
| New York | $10,001+ | $1,108,900 | 0.90% |
| Putnam | $10,001+ | $448,000 | 2.23% |
| Rockland | $10,001+ | $564,200 | 1.77% |
| Suffolk | $10,001+ | $539,500 | 1.85% |
| Westchester | $10,001+ | $638,400 | 1.57% |
| Orange | $8,463 | $361,100 | 2.34% |
| Dutchess | $7,226 | $368,100 | 1.96% |
About the figures marked with a plus. The Census Bureau caps its median tax estimate at $10,001, which stands for "$10,000 or more". Where that figure appears, the true median is higher and the effective rate shown is correspondingly understated.

New York Appeals: What Owners Ask
When is Grievance Day where I live?
The fourth Tuesday in May in most towns and cities, but there are six documented exceptions: March 15 or March 1 in New York City depending on class, March 1 in Nassau County, the third Tuesday in May in Suffolk, the third Tuesday in June in Westchester, typically the third Tuesday in February for villages that assess, and a date between the fourth Tuesday in May and the second Tuesday in June where municipalities share an assessor. Confirm yours with the assessor.
What does SCAR cost and who qualifies?
$30 to file. It is open to owners who live in their own one, two or three family home used exclusively for residential purposes, and to owners of vacant land too small to hold such a dwelling. It is the route designed for homeowners and does not require a lawyer.
Can I go straight to court?
No. Judicial review requires that you first exhaust administrative review — the grievance before the board of assessment review. Only after the board decides can you commence SCAR or a tax certiorari proceeding, and then within 30 days of the final assessment roll being filed.
Should I accept a stipulation from the assessor?
Only if it reflects what your evidence supports. A stipulation entered before Grievance Day settles the matter and bars you from asking the board for a further reduction. It is a genuine settlement, not a first offer to be improved upon later.
If I mail Form RP-524, does the postmark count?
No. The form must be received by the assessor or the board no later than Grievance Day. A postmark on the deadline is not sufficient, which makes mailing the riskiest way to file.
I own property in a town where I do not live. What are my rights?
You can request in writing — no later than 15 days before the tentative roll date, May 1 in most communities — a statement of your property, its assessed value and the time and place of grievance hearings; the assessor must send it within five days of the roll being completed. You can also ask for a hearing date after Grievance Day, provided Form RP-524 is filed on or before it, and the board must set a date within 21 days.
