Each operator shall, on or before the last day of the month or at the close of any shorter reporting period which may be established by the tax administrator, make a return on the tax administrator, on forms provided by them of the total rents charged and received and the amount of tax collected for transient occupancies; provided, however, that the operator shall pay the tax for the last quarter (April 1st-June 30th) of the fiscal year 1965-66 on or before June 30, 1966, such payment to be based upon estimates to the extent that may be necessary and any overpayment or underpayment for such quarter shall be applied against the payment for the first quarter of the 1966-67 fiscal year. At the time the return is filed, the full amount of the tax collected shall be remitted to the tax administrator. The tax administrator may establish shorter reporting periods for any certificate holder if they deem it necessary in order to insure collection of the tax and they may require further information in the return. Returns and payments are due immediately upon cessation of business or any reason. All taxes collected by operators pursuant to this chapter shall be held in trust for the account of the City until payment thereof is made to the tax administrator.
