J-51 Explanation
The J-51 benefit program of the City of New York is a tax incentive for
the renovation of multiple unit residential buildings.
The Department of Housing, Preservation and Development (HPD)
administers the program and handles all applications for it.
The Department of Finance applies the HPD approved benefits to real
property assessed value and taxes.
The program includes two benefits, both based on the certified cost of
building alteration. (1) The J-51 Exemption reduces the
taxable assessed value, which is the basis for calculating Real Estate
Taxes. (2) The J-51 Abatement reduces the actual tax that
has been charged against a property.
