Property owners and developers may be eligible for tax incentives if they:

  • Build new residential properties
  • Renovate existing properties to create residential units
  • Make certain enhancements or improvements to residential properties

The 421a Exemption Program offers benefits to developers and future and current property owners to promote multi-family residential construction. It provides a declining exemption on the new value that is created by the improvements.

The property must have at least three dwelling units.

421a benefits vary based on:

  • Location of the property
  • Whether construction is carried out with substantial government assistance, and
  • Whether requirements for affordable housing have been met

The program is administered by the NYC Department of Housing Preservation and Development (HPD). HPD determines your eligibility for this program, and the Department of Finance (DOF) implements the benefits once HPD approves your application.

Once approved, HPD will send you a Certificate of Eligibility. You must complete and submit DOF’s 421a application and include the original Certificate of Eligibility with raised seal.

Note that if you participate in the 421a program for your primary residence, you aren't eligible for other personal property exemptions, such as Senior Citizen Homeowners' Exemption (SCHE), Disabled Homeowners' Exemption, and the Veterans Exemption, until your 421a exemption expires.

Suspension Notice

In January 2019, the Department of Finance (DOF) sent notices to the owners of certain properties receiving the 421a exemption to inform them that DOF didn’t receive a Final Certificate of Eligibility (FCE) for the property. To continue receiving the benefit, owners had to submit their FCE by May 1, 2019. 

If you got a notice and didn't respond by the deadline, the property’s benefit will be suspended for the 2019/2020 tax year, and it may result in the revocation of all of the 421a exemption benefits on your property retroactive to the date on which the property initially began to receive these benefits.  

If you have any questions, please email 421Aexemption@finance.nyc.gov.
