161.05 RETURN AND PAYMENT OF TAX.
   (a)   Each taxpayer shall whether or not a tax be due thereon, make and file a return on or before April 15 of each calendar year. When the return is made for a fiscal year or other period different from the calendar year, the return shall be filed not later than the 15th day of the fourth month after the end of such fiscal year or period.
   (b)   The return shall be filed with the Tax Administrator on a form or forms furnished by or obtainable upon request from such Tax Administrator setting forth:
      (1)    A.   The aggregate amount of salaries, wages, commissions and other compensation earned;
         B.    The gross income from a business, profession or other activity less allowable expenses incurred in the acquisition of such gross income;
         C.   Such income shall include only income earned during the year, or portion thereof, covered by the return and subject to the tax imposed by this chapter;
      (2)    A.    The amount of tax imposed by this chapter on income reported;
         B.   Any credits to which the taxpayer may be entitled under the provisions of Sections 161.06, 161.07 and 161.15 of this chapter; and
      (3)   Such other pertinent statements, information returns or other information as the Tax Administrator may require.
   (c)    The Tax Administrator may extend the time for filing of the annual return upon the request of the taxpayer for a period of not to exceed six months, or one month beyond any extension requested of or granted by the Internal Revenue Service for the filing of the Federal income tax return. The Tax Administrator may require a tentative return, accompanied by payment of the amount of tax shown to be due thereon, by the date the return is normally due. Interest shall be assessed according to the provisions of Section 161.10 in those cases in which the return is filed and the final tax paid within the period as extended. No penalty shall be assessed in the above cases.
   (d)    (1)    The taxpayer making a return shall, at the time of the filing thereof, pay to the Tax Administrator the balance of tax due, if any, after deducting:
         A.   The amount of the City income tax deducted or withheld at the source pursuant to Section 161.06;
         B.   Such portion of the tax as has been paid on declaration by the taxpayer pursuant to Section 161.07;
         C.   Any credit allowable under the provisions of Section 161.15.
      (2)   Should the return or the records of the Tax Administrator indicate an overpayment of the tax to which the City is entitled under the provisions of this chapter, such overpayment shall first be applied against any existing liability and the balance, if any, at the election of the taxpayer communicated to the Tax Administrator in writing, shall be refunded or applied against any subsequent liability.
   (e)    (1)    Where necessary, an amended return must be filed in order to report addi tional income and pay any additional tax due, or claim a refund of tax over paid, subject to the requirements and/or limitations contained in Sections 161.11 and 161.15. Such amended returns shall be on a form obtainable on request from the Tax Administrator. 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 City tax liability, such taxpayer shall make and file an amended City return showing income subject to the City tax based upon such final determination of Federal tax liability, and pay any additional tax shown due thereon or make claim for refund of any overpayment.
   (f)   A taxpayer may not change the method of accounting, apportionment of net profits or elect to file a consolidated return after the original due date of the filing.
