About the Tax Commission

The Tax Commission is the City of New York's forum for independent administrative review of real property tax assessments set by the Department of Finance.

In accordance with New York State and local law, the Tax Commission reviews and determines annual applications for correction of assessment filed by owners and other parties with a sufficient legal interest in properties they claim are incorrectly assessed or improperly denied an exemption from real property tax.

There are four real property tax assessment-related claims subject to review and corrective action by the Tax Commission: 1. Excessive assessment; 2. Misclassification; 3. Unequal assessment; and 4. Unlawful assessment. The claims are summarized, as follows: Excessiveness covers claims that an assessment cap has been exceeded or a partial exemption claim. Inequality, the most common claim, compares your assessment to the assessments of all other real property in the same tax class. Unlawfulness covers claims for complete exemption from taxation, that the property is entirely outside the city limits, or that the City lacks authority to assess the property. Misclassification is a claim that the assessment roll designates an incorrect tax class for the property. To read the complete definition of each of these claims, as set forth in the City Charter and New York State law, click here.

If you are considering filing an appeal with the Tax Commission, take a moment to make sure the Tax Commission is where you should direct a protest. Look at the Notice of Value you received from Finance.

On your Notice of Value for properties in tax class 1 and in tax class 2 if there are fewer than 11 units, you will see both a "market value" and a "value that your tax is based on."

The Tax Commission can only adjust your assessed value (and in turn the value your tax is based on). You should file an appeal only if you can prove that the market value of your property is less than the value your tax is based on.

The Tax Commission does not adjust Finance's estimated market value because Finance's estimate alone has no impact on your taxes if that estimate exceeds the value your tax is based on. If you are seeking an adjustment of your property's market value or changes in descriptive data, such as the age or size of your property, contact the Department of Finance. Click here to learn how to contact Finance about its estimated market value or descriptive data.

Please Note: Inquires about tax bills, income taxes, and all other taxes, tax liens, tax amnesty, tax payments, interest on delinquent taxes, and the real property tax assessment process should be sent to the Department of Finance. Click here to contact the Department of Finance on these matters. The authority of the Tax Commission is limited to the review of real property tax assessments set by the Department of Finance only in the current year and, in certain circumstances, one earlier year.

Tax Commission's administrative determinations are subject to de novo judicial review. Click here for further instructions and information about assessments and the assessment review process.

The Tax Commission comprises a president and six Commissioners appointed by the Mayor, with advice and consent of the City Council, to six-year terms. The President, as the head of the agency, serves full-time; the six Commissioners serve part-time. Each member of the Commission must have at least three years of business experence in real estate or real estate law. The Commission must include at least one resident of each borough.

The Tax Commission diligently tries to ensure sound determinations of assessment challenges for all classifications and types of real property throughout the five boroughs. The Tax Commission is committed to the highest standards of performance and integrity. We strive to deliver efficient, productive and courteous service to the taxpayers and professional representatives pursuing administrative review of real property tax assessments within the City.
