(a) Whenever an employer required to deduct and withhold taxes as required under this article fails, at the time and in the manner prescribed by law or regulation, to deduct and withhold, collect, account truthfully for, or pay over to the commissioner the amount of taxes due as required by this article, upon being notified of the failure by the commissioner by notice served upon him, personally or by registered or certified mail or statutory overnight delivery addressed to his last known address, he shall comply with the requirement of special accounting as set forth in subsection (b) of this Code section.

(b) Beginning at the time of service upon him of the notice provided for in subsection (a) of this Code section, the employer shall deduct and withhold the tax required under this article and, not later than the second banking day after any amount of such tax is deducted and withheld, shall:

(1) Deposit the tax in a special and separate account in any state or national bank designated as a state depository and keep the amount of such taxes in such account until payment over to the commissioner or to the department. Each such account shall be a special fund in trust for the state payable only to the commissioner or the department; or

(2) Purchase a postal money order or other certified or bankable paper for such amount, payable only to the commissioner or the department. The order or paper shall be handled and dealt with under such rules and regulations as the commissioner may prescribe.

(c) Whenever the commissioner is satisfied that the special accounting prescribed under subsections (a) and (b) of this Code section is no longer necessary to effect future compliance with law or regulations, he may cancel the notice requiring compliance with subsection (b) of this Code section at such time and under such conditions as he may specify.
