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:

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.
