Benefits paid to employees of nonprofit organizations shall be financed in accordance with the provisions of this section. For the purpose of this section, a nonprofit organization is an organization (or group of organizations) described in section 501(c) (3) of the "U.S. Internal Revenue Code" which is exempt from income tax under section 501(a) of such code.
At the end of each calendar quarter, or at the end of such other period as determined by the commissioner, the commissioner shall bill each nonprofit organization for an amount representing one of the following:
At the end of each taxable year, the commissioner may modify the quarterly percentage of payroll thereafter payable by the nonprofit organization in order to minimize excess or insufficient payments.
At the end of each taxable year, the commissioner shall determine whether the total of payments for such year made by a nonprofit organization is less than, or in excess of, the total amount of regular benefits plus one half of the amount of extended benefits paid to individuals during such taxable year based on wages attributable to service in the employ of such organization. Each nonprofit organization whose total payments for such year are less than the amount so determined shall be liable for payment of the unpaid balance to the fund in accordance with subparagraph (c) of this subdivision (2). If the total payments exceed the amount so determined for the taxable year, all or a part of the excess may, at the discretion of the commissioner, be refunded from the fund or retained in the fund as part of the payments which may be required for the next taxable year.
