Challenge your property’s assessed value

If you disagree with the assessed value on your annual Notice of Property Value (NOPV), you can appeal with the New York City Tax Commission, an independent agency.

The Tax Commission can reduce your property's assessment, change its tax class, and adjust exemptions.

Before filing with the Tax Commission, review your NOPV. If your property has an "effective market value," you will need to prove that your current market value is less than the effective market value in order to win your Tax Commission appeal.

Tax Commission appeal deadlines:

March 15 (tax class 1)

March 1 (tax classes 2, 3, and 4)

Appeals received after these dates will not be granted.
