The market value of a property is the City’s estimate of your property's worth. The assessment also considers the value of any land on the property. Market value is listed on the Annual Notice of Property Value (NOPV) that you receive every January.

If you own a Tax Class 1, 2, or 4 property and think the market value on your NOPV is incorrect, you can file a Request for Review. If you own a Class 2 or Class 4 property, you can also request a review of your tax class, gross income, gross expenses, and gross square footage.

If you own a co-op or condo unit, your managing agent or board of directors should file the request on behalf of the entire building or development.

Even if DOF agrees to change your market value, this isn’t likely to immediately change the amount of taxes you owe. To change the amount of your property taxes, you need to appeal your assessed value. Visit the Property Value Appeal page to learn how to challenge your assessed value.

The Department of Finance (DOF) calculates your market value based on State-mandated statistics and your tax class.

  • Tax Class 1: DOF uses sale prices of similar properties in similar neighborhoods to determine market value.
  • Tax Class 2: Co-ops and condos are treated as if they are income-producing, based on their income and expenses for similar rental buildings.
  • Tax Class 4: Commercial or industrial property is valued based on one of three methods:
    • The Real Property Income and Expense (RPIE) statements filed annually
    • The sale price of similar property
    • The value of the land and the cost of constructing, reproducing, or replacing the building

If you need more information about the market value of your property, you can get help from the Borough Assessor Office.

Contact the Borough Assessor.

Income-Producing Properties

The Department of Finance needs income and expense information from certain income-producing properties to determine the value and property tax.

If you own an income-producing property in a Tax Class other than Tax Class 1, you’re required to file a Real Property Income and Expense Statement (RPIE) or a Claim of Exclusion, unless you are exempt by law.

Learn more about the RPIE on the Real Property Income Expense (RPIE) page.

Request for Review applications must be filed in person or postmarked by the due date. Deadlines cannot be extended.

2019/2020 Tax Year

  • Tax Class 1: March 15, 2019

You can file for an administrative review if you think the Department of Finance made a clerical mistake in the amount of your property’s assessed value or market value.

Tax Classes

Every property in New York City is assigned to a tax class based on the property's size and how it is used.

Class 1
Class 2
1-, 2-, and 3-family homes

Condo buildings that are 3 stories or less

Small stores or offices with 1-2 apartments attached

Vacant land that is zoned for residential use 
Property that isn't in Class 1 and is mostly residential

Residential property with 4 or more units

Co-op and condo buildings that are 4 stories or higher

Small stores or offices with 2 or more apartments attached

 

Class 3
Class 4
Property with equipment owned by a gas, telephone, or electric company 
All commercial and industrial property, such as offices and factories

Vacant land that is not zoned for residential use 

Vacant Land

All vacant land in Manhattan is classified as Class 4 property, regardless of use.

In the City's other boroughs, the vacant land tax class depends on how it's used. If it's zoned for commercial use, it is taxed as commercial property. If zoned for residential use, it is taxed as residential property.

The amount is based on comparable sales of other vacant land.
