Sec. 19-530. When tax due; when delinquent; verification of return; extensions.
   (a)   When Tax Due. Except as provided elsewhere in this section, the taxes shall be due and payable monthly on or before the twentieth day of the month next succeeding the month in which the tax accrues.
   (1)   Quarterly returns. The tax collector may authorize a taxpayer whose reporting history indicates an estimated annual city privilege and use tax liability on taxable gross income in excess of five thousand dollars ($5,000.00) but less than fifty thousand dollars ($50,000.00) to file returns on a calendar-quarterly basis. The taxes for each calendar quarter shall be due and payable on or before the twentieth day of the month next succeeding the end of each calendar quarter.
   (2)   Annual returns. The tax collector may authorize a taxpayer whose reporting history indicates an estimated annual city privilege and use tax liability on taxable gross income of not more than five thousand dollars ($5,000.00) to file returns for such taxes on a calendar- annual basis. The taxes for each calendar year shall be due and payable on or before the twentieth day of January of the following year.
   (b)   Special Requirements of Taxpayers Filing Quarterly or Annual Returns. No taxpayer may report on a quarterly or annual basis until he has established, to the tax collector's satisfaction, six (6) months' reporting history. It is the taxpayer's responsibility to notify the tax collector and increase his reporting frequency (to quarterly or monthly as applicable) when his taxable income or tax due exceeds the maximum limits for his current reporting frequency. Failure to do so may be deemed negligence or evasion, and penalties may apply. Failure to file returns timely, without good cause shown to the satisfaction of the tax collector, is sufficient cause for the tax collector to deny future filings by the taxpayer on a quarterly or annual basis.
   (c)   Delinquency Date. Except as provided in subsection (d) below, all returns and remittances received within the tax collector's office on or before the last business day of the month when due shall be regarded as timely filed. The start of business of the first business day following the month when due shall be the delinquency date. It shall be the taxpayer's responsibility to cause his return and remittance to be timely received. Mailing the return or remittance on or before the due date or delinquency date does not relieve the taxpayer of the responsibility of causing his return or remittance to be received by the last business day of the month when due.
   (d)   Jeopardy reporting. If the tax collector determines that the collection of any tax due to the city is in jeopardy, the tax collector may direct the taxpayer to file his return and remit the tax on a weekly, daily or transaction-by-transaction basis. Such return and remittance shall be due upon the date fixed by the tax collector, and the delinquency date shall be the following day.
   (e)   Extensions. The tax collector may extend the time for filing a return, for good cause shown, and only when requested in writing and received by the tax collector prior to the tax due date. However, the time for filing such return shall not be extended beyond the next to last business day of the month next succeeding the due date of such return. In such cases, only the penalties for late filing and late payment may be waived by the tax collector for filing and payment within the extension period. Notwithstanding the granting of an extension, the interest payable for late payment of taxes shall be paid for the period commencing upon the original delinquency date and ending on the date the tax is paid. The interest may not be waived by the tax collector.
