§ 91.05 RETURN AND PAYMENT OF TAX.
   (A)   Dates. Every person, including, but not limited to those who engages in a business or other activity or whose qualifying wage, commissions, other compensation, and other taxable income is subject to the tax imposed by this Tax Code, shall, whether or not a tax be due thereon, make and file a return on or before April 15 of the year following the effective date of this Tax Code, and on or before April 15 of each year thereafter. When the return is made for a fiscal year or other period different from the calendar year, the return shall be filed on or before the fifteenth day of the fourth month following the end of such fiscal year or period.
   (B)   A husband and wife may file either separate returns or a joint return for municipal purposes, even though one of the spouses has neither taxable income nor deductions included on the Municipal return regardless of whether their federal and state returns were filed separately or jointly. If a joint Municipal return is made, the tax shall be computed on the aggregate taxable income and the liability with respect to the tax shall be joint and several.
   (C)   The return shall be filed with the Tax Commissioner on a form or forms furnished by or obtainable upon request from the Tax Commissioner; or on a generic form, if the generic form, when completed and filed, contains all of the information required to be submitted with the municipality's prescribed return and, if the taxpayer or return preparer filing the generic form otherwise complies with the Tax Code governing the filing of returns.
   (D)   The return shall set forth:
      (1)   The aggregate amounts of qualifying wages, commissions, and other compensation earned, received, apportioned or set aside, other income defined by statute as taxable, and gross income from any business, profession, or other activity, less allowable expenses incurred in the acquisition of such gross income earned during the preceding year and subject to such tax; and
      (2)   The amount of the tax imposed by this chapter on such earnings and profits; and
      (3)   Such other pertinent statements, information returns, copies of federal or state tax returns and/or schedules, or other relevant information as the Tax Commissioner may require including a statement that the figures used in the return are the figures used in the return for federal income tax adjusted to set forth only such income as is taxable under the provisions of this chapter.
   (E)   Extensions.
      (1)   Any taxpayer that has requested an extension for filing a federal income tax return may request an extension for the filing of a municipal income tax return by filing a copy of the taxpayer's request for a federal filing extension with the Tax Commissioner. Any taxpayer not required to file a federal income tax return may request an extension for filing a municipal income tax return in writing. The request for extension must be filed on or before the original due date for the annual return. If the request is granted, the extended due date of the municipal income tax return shall be the last day of the month following the month to which the due date of the federal income tax return has been extended.
      (2)   The Tax Commissioner may deny a taxpayer's request for extension if the taxpayer:
         (a)   Fails to timely file the request; or
         (b)   Fails to file a copy of the federal extension request (if applicable); or
         (c)   Owes the municipality any delinquent income tax, penalty, interest, assessment or other charge for the late payment or nonpayment of income tax; or
         (d)   Has failed to file any required income tax return, report, or other related document for a prior tax period.
      (3)   The granting of an extension for filing a municipal income tax return does not extend the last date for payment of the tax; hence, penalty and interest may apply to any unpaid tax during the period of extension at the rate set out by § 91.10. No penalty shall be assessed in those cases in which the return is filed and the final tax paid within the extension period provided all other filing and payment requirements of the tax code have been met. Any extension by the Tax Commissioner shall be granted with the understanding that declaration filing and payment requirements have been fulfilled; however, if, upon further examination it then becomes evident that declaration filing and payment requirements have not been fulfilled, penalty and interest may be assessed in full and in the same manner as though no extension had been granted.
   (F) Payment with returns.
      (1)   The taxpayer making a return shall, at the time of the filing thereof, pay to the Tax Commissioner the amount of taxes shown as due. However, credit shall be allowed for:
         (a)   Any portion of the tax so due which shall have been deducted at the source pursuant to the provisions of § 91.06; and
         (b)   Any portion of said tax which shall have been paid by the taxpayer pursuant to the provisions of § 91.06, and
         (c)   Credit to the extent allowed by § 91.15 for tax paid to another municipality.
         (d)   Any additional tax owed by a resident taxpayer incurred as a result of the tax credit allowed by § 91.15 being reduced by 25% effective January 1, 2013, through December 31, 2013, may be paid in full by April 15, 2014, or in four equal installments on April 30, 2014, July 31, 2014, October 31, 2014 and January 31, 2015.
      (2)   A taxpayer who has overpaid the amount of tax to which the Municipality is entitled under the provisions of this chapter may have such overpayment applied against any subsequent liability hereunder, or, at his election indicated on the return, such overpayment, or any part thereof, shall be refunded, provided that no additional taxes or refunds of less than $1.00 shall be collected or refunded.
   (G)   Amended returns.
      (1)   Where necessary, an amended return shall be filed in order to report additional income and to pay any additional tax due, or to claim a refund of tax overpaid, subject to the requirements and/or limitations contained in §§ 91.11 and 91.15. Such amended returns shall be on a form acceptable to the Tax Commissioner. A taxpayer may not change the method of accounting or apportionment of net profits after the due date for filing the original return.
      (2)   Within three months from the final determination of any federal tax liability affecting the taxpayer's Municipal tax liability, such taxpayer shall make and file an amended Municipal return showing income subject to the Municipal tax based upon such final determination of federal tax liability, and shall pay any additional tax shown due thereon or make claim for refund of any overpayment.
