View exemption application (opens in a new tab)Senior relief
New York senior-citizen exemption (RPTL §467) is locally adopted; qualifying owners are generally age 65+ and subject to the income limit set by the county, city, town, village, or school district, with up to a 50% assessed-value reduction. Basic and Enhanced STAR provide school-tax relief; new applicants register for the STAR credit with NYS, while Enhanced STAR is for eligible owners age 65+ subject to the current income limit. Confirm the local scale with the municipal assessor.
Valuation limits
No general countywide assessed-value cap verified. New York requires annual assessment at a uniform percentage of market value; the New York property-tax cap limits annual tax-levy growth (generally 2% or inflation, with exceptions), not an individual parcel's assessed value.
For a valuation appeal, use the appeal date in the tax and filing section above. Keep your notice, supporting evidence, and proof of submission.
