A municipality may also grant the senior-citizens exemption of up to 50% under RPTL §467, subject to its local income limit; file RP-467 or RP-467-Rnw with the local assessor, usually by March 1.
Valuation limits
New York's property-tax cap limits the annual levy of participating local governments and most school districts to the lower of 2% or inflation, with override provisions; it is not an individual parcel assessed-value cap.
