The taxes levied hereunder shall be due and payable in quarterly installments on or before the expiration of one month from the end of the quarter in which they accrue. The taxpayer shall, within the one month from the expiration of each quarter, make out on a form provided by the City an estimate of the tax for which he is liable for such quarter, sign the same, and mail the same together with a remittance of the amount of tax to the City. In estimating the amount of the tax due for each quarter, the taxpayer may deduct one-fourth of the total exemption allowed for the year. When the total tax for which any person is liable under this article does not exceed the sum of one hundred dollars ($100.00), in any year, the taxpayer may pay the same quarterly as aforesaid, or with the consent in writing of the City Treasurer at the end of the month next following the close of the tax year. Any other provision of this article notwithstanding, Council if it is deemed necessary to insure payment of the tax, may require the return and payment under this article for periods of shorter duration than quarter-year periods.
