The  Assessor

The Assessor is appointed by the Mayor and approved by the Common Council as a local government official.  The assessor is obligated by New York State law to maintain assessments at a uniform percentage of market value each year.  To do this the Assessor’s Office maintains an inventory of all parcels located in the city.  The City of Rensselaer has approximately 3,300 parcels.  Our mission is to ensure fairness and equity in the valuation of all real property located in the City and to treat each property owner in a polite and professional manner.

The STAR program has transitioned to:                 School Tax Relief (STAR) Credit

NEW STAR applicants will receive a credit in the form of a check directly from New York State instead of receiving a school property tax exemption. The amount of your STAR benefit is the same regardless of how you receive it. 

If you are already enrolled in the STAR program this will not apply to you. Current Basic and Enhanced STAR recipients will keep their exemptions as long as they continue to own their current homes.

NEW Basic and Enhanced STAR applicants must register with the New York State Tax Department to receive a STAR credit check. Visit or call (518) 457-2036.
