Constitution of the State of New York Art. VIII § 10. [Limitations on amount to be raised by real estate taxes for local purposes;  exceptions]

(a) any county, for county purposes, one and one-half per centum;  provided, however, that the legislature may prescribe a method by which such limitation may be increased to not to exceed two per centum;

(b) any city of one hundred twenty-five thousand or more inhabitants according to the latest federal census, for city purposes, two per centum;

(c) any city having less than one hundred twenty-five thousand inhabitants according to the latest federal census, for city purposes, two per centum;

(e) Notwithstanding the provisions of sub-paragraphs (a) and (b) of this section, the city of New York and the counties therein, for city and county purposes, a combined total of two and one-half per centum.

The average full valuation of taxable real estate of such county, city, village or school district shall be determined by taking the assessed valuations of taxable real estate on the last completed assessment rolls and the four preceding rolls of such county, city, village or school district, and applying thereto the ratio which such assessed valuation on each of such rolls bears to the full valuation, as determined by the state tax commission or by such other state officer or agency as the legislature shall by law direct.  The legislature shall prescribe the manner by which such ratio shall be determined by the state tax commission or by such other state officer or agency.

Nothing contained in this section shall be deemed to restrict the powers granted to the legislature by other provisions of this constitution to further restrict the powers of any county, city, town, village or school district to levy taxes on real estate.
