How to Appeal Property Tax in New York (Step-by-Step Guide)

If you believe your property is over-assessed, you may be able to reduce your property tax by filing an appeal. Many homeowners in New York overpay simply because they never check their assessment.

This guide explains how to appeal property tax in New York, what form to use, and how to decide if it's worth filing.

Step 1: Review Your Property Assessment

Property tax in New York is based on your property's assessed value. Start by reviewing your assessment and comparing it with similar homes in your area.

Step 2: Compare With Similar Properties (Comps)

Look at recent sales of comparable properties nearby. If your home is assessed higher than similar properties, you may have a valid reason to appeal.

Step 3: Prepare Supporting Information

You may include:

• Comparable property sales
• Photos showing property condition
• Any issues affecting value

Step 4: File Form RP-524

To appeal property tax in New York, homeowners must file Form RP-524 with their local assessor or Board of Assessment Review.

This form allows you to formally challenge your property's assessed value.

New York Property Tax Appeal Deadline

In most towns, the deadline to file Form RP-524 is around May (Grievance Day). Exact dates may vary slightly depending on your location.

NYC vs Other Counties

In New York City, the process is handled through the NYC Tax Commission, not Form RP-524. In other counties like Suffolk and Nassau, RP-524 is required.

Is It Worth Appealing Property Tax?

Not every appeal results in a reduction, but many homeowners never check their assessment at all.

Submitting gives you a chance. Not submitting guarantees you miss it.
