880.20   RETURN AND PAYMENT OF TAX.
   (a)   On or before April 15 of each calendar year, for taxable years beginning after 2003, every taxpayer engaged in any business, the net profits of which are subject in whole or in part to the tax imposed by this chapter, shall make and file with the Clerk-Treasurer a final return on a form furnished by or obtainable from the Clerk- Treasurer. All resident taxpayers, eighteen years of age or older, that are required to file a Federal Income Tax Return must file a return with the Clerk-Treasurer on a form furnished by or obtainable from the Clerk-Treasurer. Failure to file shall be punishable as provided in this chapter. Senior citizen residents of the Municipality who are not required to file a Federal Income Tax Return are exempt from filing a tax return with the Municipality unless and until said resident experiences a change of income status. However, where a nonresident employee's entire earnings for the year are paid by an employer and the Municipal tax thereon has in each instance been withheld and deducted by the employer from the gross amount of the entire earnings of such employee-taxpayer, and where the employer of such nonresident employee has filed a report or return in which such employee's entire and only earnings are reported to the Clerk-Treasurer, and where such nonresident employee has no taxable income other than such earnings, it shall not be necessary for such nonresident employee to file a return for any taxable year in which such conditions have prevailed.
   Any person who receives both compensation for services performed for an employer, in whatsoever form, and in addition receives income from any business activity or occupation not subject to withholding under this chapter, must file a declaration and a final return.
   (b)   In all returns filed hereunder there shall be set forth the aggregate amount of salaries, wages, bonuses, incentive payments, commissions, fees and other compensation received and/or net profits earned (all as hereinbefore defined) by and during the preceding year and subject to said tax, together with such pertinent information as the Clerk-Treasurer may require.
   (c)   If the return is made for a fiscal year or for any period other than a calendar year, the said return shall be made within four months from the end of said fiscal year.
   (d)   The return shall also show the amount of the tax imposed by this chapter on such earnings, or net profits, or both.
   (e)   The taxpayer making the return shall, at the time of filing thereof, pay the Clerk-Treasurer the amount of tax shown to be due and unpaid by the return. If, pursuant to the provisions of Section 880.26, the taxpayer has at the time of making such final return overpaid his tax, such taxpayer shall show the amount of overpayment and may in said return either (1) request a refund therefor, or (2) request that the amount thereof be credited against the amount which will be required to be paid by taxpayer on the next succeeding installment of tax which may become due.
   (f)    Where any portion of the tax otherwise due shall have been paid by the taxpayer pursuant to the provisions of Sections 880.21 and 880.25, or where an income tax has been paid to another municipality, pursuant to Section 880.16, credit for the amount so paid shall be deducted from the amount shown to be due and only the balance, if any, shall be due and payable at the time of filing said final return.
   (g)   Upon written request of the taxpayer, the Clerk-Treasurer may extend the time for filing the annual return for a period of not more than six months or not more than thirty days beyond any extension requested of and granted by the Federal Internal Revenue Department for the filing of the Federal Income Tax Return.
   (h)   For payments in installments, see Section 880.26.
