Payment of tax

18. Every person required to file a return under this act shall, at the time of filing such return, pay to the director the taxes imposed by this act as well as all other moneys collected by such person acting or purporting to act under the provisions of this act. All the taxes for the period for which a return is required to be filed or for such lesser interval as shall have been designated by the director, shall be due and payable to the director on the date limited for the filing of the return for such period, or on the date limited for such lesser interval as the director has designated, without regard to whether a return is filed or whether the return which is filed correctly shows the amount of receipts, amusement charges or rents or the value of property or services sold or purchased or the taxes due thereon. Where the director, in the director's discretion, deems it necessary to protect the revenues to be obtained under this act, the director may require any person required to collect the tax imposed by this act to file a bond with the director, issued by a surety company authorized to transact business in this State and approved by the Commissioner of Banking and Insurance of this State as to solvency and responsibility, in such amount as the director may fix, to secure the payment of any tax or penalties or interest due or which may become due from such person under this act. In the event that the director determines that a seller is to file such bond, the director shall give notice to the seller to that effect, specifying the amount of the bond required. Such person shall file such bond within 5 days after the giving of such notice unless within such 5 days that person shall request in writing a hearing before the director at which the necessity, propriety and amount of the bond shall be determined by the director. Such determination shall be final and shall be complied with within 15 days after the giving of notice thereof. In lieu of such bond, securities approved by the director or cash in such amount as the director may prescribe, may be deposited, which shall be kept in the custody of the director who may at any time without notice to the depositor apply them to any tax or interest or penalties due, and for that purpose the securities may be sold by the director at public or private sale without notice to the depositor thereof.
