Exemptions & appeals
View exemption application (opens in a new tab)Exemption filing
March 1, 2026 for most local New York property-tax exemptions; file RP-467/RP-467-Rnw and other applicable forms with the applicable city, town, or village assessor by the taxable-status date. New STAR applicants generally register for the NYS STAR credit rather than a new local exemption.
Senior relief
New York's 2026 Enhanced STAR benefit is for a qualifying owner-occupied primary residence with at least one resident owner age 65 or older by December 31 and combined income of resident owners and spouses of $110,750 or less. A municipality may also grant the senior-citizens exemption under RPTL §467, reducing assessed value by up to 50% subject to its local income limit; file RP-467 or RP-467-Rnw with the local assessor, usually by March 1.
Valuation limits
Ontario County's official tax-cap guidance states the New York tax cap limits the tax levy, not tax rates, assessments, or individual tax bills; counties, towns, cities, villages, and special districts may override the levy limit by local law.
For a valuation appeal, use the appeal date in the tax and filing section above. Keep your notice, supporting evidence, and proof of submission.
