Section 372 - Tax and revenue anticipation fund1. The board of supervisors of a county by resolution may establish a revolving fund to be known as the tax and revenue anticipation fund. There may be paid into such fund in the fiscal year in which it is established an amount which shall not exceed thirty per centum of the total estimated expenditures as contained in the budget of the county for such fiscal year. In subsequent fiscal years, additional amounts may be paid into such fund, provided that any such payment shall not increase the total amount of such fund to an amount greater than thirty per centum of the total estimated expenditures as contained in the budget of the county for the fiscal year in which such payment is made. Such amounts may be provided by budgetary appropriation or from moneys of the county which are not required by law to be paid into another fund or account.2. The moneys in such fund may be used only for the purpose of investment in non-interest bearing tax anticipation or revenue anticipation notes of the county, or renewals thereof. Any provisions of law to the contrary notwithstanding, all tax or revenue anticipation notes of the county, or renewals thereof, sold to the tax and revenue anticipation fund during a fiscal year shall be paid on or before the close of such fiscal year.3. The moneys in such fund, pending investment as provided in subdivision two of this section, shall be deposited in one or more banks or trust companies designated in the manner provided by law, as depositaries of funds of the county. The moneys in any such fund so deposited shall be accounted for separate and apart from all other funds of the county, in the same manner as provided in subdivision ten of section six-c of the general municipal law. Any interest earned on the moneys so deposited shall be a general county revenue.4. Such fund shall continue in existence from year to year, provided, however, that the board of supervisors by resolution may transfer all or part of the moneys in such fund to a reserve fund established pursuant to article two of the general municipal law.
