New York Consolidated Laws, Real Property Tax Law - RPT § 925-b. Extension;  certain persons sixty-five years of age or over

Notwithstanding any contrary provision of this chapter, or any general, special or local law, code or charter, the governing body of a municipal corporation other than a county may, by resolution adopted prior to the levy of any taxes on real property located within such municipal corporation, authorize an extension of no more than five business days for the payment of taxes without interest or penalty to any resident of such municipal corporation who has received an exemption pursuant to subdivision four of section four hundred twenty-five or four hundred sixty-seven of this chapter, or a credit pursuant to subsection (eee) of section six hundred six of the tax law, related to a principal residence located within such municipal corporation.  If such an extension is granted, and any taxes are not paid by the final date so provided, those taxes shall be subject to the same interest and penalties that would have applied if no extension had been granted.
