(3) Such agreement shall include:

(a) the procedure under which the New York state higher education services corporation shall notify the commissioner of a default in repayment of a governmental education loan, such procedure to specify when the commissioner shall be notified and the content of such notification;

(b) the minimum amount outstanding on a default in repayment of a governmental education loan against which the commissioner shall, pursuant to this section, credit an overpayment;

(4) (i) In calculating the amount of an overpayment and interest thereon which shall be credited against the amount of a default in repayment of a governmental education loan owed by a taxpayer, the commissioner shall first credit the overpayment and interest thereon against any:

(A) liability of such taxpayer in respect of any tax imposed by this chapter;

(B) liability of such taxpayer for any tax imposed pursuant to the authority of this chapter or any other law if such tax is administered by the tax commission;

(C) estimated tax for the succeeding taxable year if such taxpayer claims such overpayment or a portion thereof as a credit against estimated tax for such succeeding taxable year pursuant to subsection (e) of section six hundred eighty-six of this chapter or subdivision (e) of section 11-1786 of the administrative code of the city of New York for any tax imposed pursuant to the authority of this chapter or any other law if such tax is administered by the tax commission; and

(ii) Only the balance remaining, after such overpayment and the interest thereon has been credited as described in paragraph (i) of this subdivision, shall be certified as an overpayment plus any interest to be credited against the amount of a default in repayment of a governmental education loan, with the remainder to be refunded to the taxpayer.

(5) The tax commission shall certify to the comptroller the total amount of the overpayment and the interest on such overpayment, the amount of such overpayment and the interest on such amount to be credited against the amount of the default in repayment of a governmental education loan and the balance of such overpayment and interest to be refunded to the taxpayer.

(6) The commissioner shall notify the taxpayer making the overpayment, in writing, of the amount of such overpayment and the interest thereon certified to the comptroller as the amount to be credited against the amount of a default in repayment of a governmental education loan. Such notice shall include notification to any other person who may have filed a joint return with the taxpayer of the steps such other person may take in order to secure his or her proper share of the refund.

(7) From the time the state tax commission is notified by the New York state higher education services corporation of an individual's, estate's or trust's default in repayment of a governmental education loan under the agreement provided for in this section, the state tax commission and the department shall be relieved from all liability to such individual, estate or trust, their assigns, successors, heirs or representatives for the amount of an overpayment and interest on such amount certified to the comptroller to be credited against the amount of default in repayment of a governmental education loan and such individual, estate or trust shall have no right to commence a court action or proceeding or to any other legal recourse against the state tax commission or the department to recover such overpayment or such interest certified to the comptroller to be credited against the amount of default in repayment of a governmental education loan. Provided, however, nothing herein shall be construed to prohibit such individual, estate or trust from proceeding against the New York state higher education services corporation to recover that part of such overpayment or interest thereon so certified to the comptroller to be credited against the amount of a default in repayment of a governmental education loan which is greater than the amount of such default owed by such individual, estate or trust on the date of such certification.

(8) The tax commission shall promulgate such rules and regulations as it deems necessary to carry out the provisions of this section.
