§ 550. County treasurer; duties. 1. The county treasurer shall perform the duties prescribed by law as the chief fiscal officer of the county. Such county treasurer shall perform such additional and related duties as may be prescribed by law and directed by the board of supervisors.

2. The county treasurer shall receive and be the custodian of all money belonging to the county or in which the county has an interest and shall keep a true account of all receipts and the expenditures in books provided by him at the expense of the county.

3. On or before the first day of March in each year the county treasurer shall furnish a statement of and pay over to the state comptroller all penalties or moneys belonging to the state. Any state tax levied as part of the county tax shall be paid to the state comptroller on or before the fifteenth day of May in each year. The county treasurer, the county and the surety or sureties on the official undertaking of such county treasurer shall be liable to the state for all moneys collected and belonging to the state and for any state tax levied as a part of the county tax together with interest not exceeding ten per centum per annum, to reimburse the state for any borrowing occasioned by any failure to pay the same to the state.

4. On or before the tenth day of January in each year, the county treasurer shall transmit to the town clerk of each town within his county a statement of all moneys paid by said county treasurer to the supervisor of the town during the preceding year.

5. The county treasurer shall disburse all moneys received from the fish and wildlife service of the United States department of the interior pursuant to section seven hundred fifteen-s of the migratory bird conservation act on a proportional basis to those units of local government, including, but not limited to school districts and the county itself in appropriate cases, which have incurred the loss or reduction of real property tax revenues by reason of the existence of such areas. Where such moneys are to be paid to the supervisors of towns, in a case where any such wildlife refuge lands are located wholly within the boundaries of an incorporated village, such moneys shall be paid to the board of trustees of such village. Such moneys shall be used exclusively for town or village highway purposes, as the case may be. Where such moneys are paid to treasurers or other fiscal officers of a school district, such moneys shall be used exclusively for public school purposes. Upon request, a district superintendent of schools shall furnish to the county treasurer such data as he may require to effectuate the disbursement of moneys under this subdivision.

6. The board of supervisors may, by resolution, determine to enter into a contract to provide for the deposit of the periodic payroll of the county in a bank or trust company for disbursal by it in accordance with the provisions of section ninety-six-b of the banking law.
