701—58.2 (422) Time and place for filing return.
	 58.2(1) Returns of financial institutions. A return of income for all financial institutions must be filed on or before the delinquency date. The delinquency date for all financial institutions is the day following the last day of the fourth month following the close of the taxpayer’s taxable year, whether the return is made on the basis of the calendar year or the fiscal year; or the day following the last day of the period covered by an extension of time granted by the director. When the last day prior to the delinquency date falls on a Saturday, Sunday or a legal holiday, the return will be timely if it is filed on the first business day following the Saturday, Sunday or legal holiday. If a return is placed in the mails, properly addressed and postage paid in ample time to reach the department on or before the delinquency date for filing, no penalty will attach should the return not be received until after that date. Mailed returns should be addressed to Franchise Tax Processing, P.O. Box 10413, Des Moines, Iowa 50306.
	 58.2(2) Short period returns. Where under a provision of the Internal Revenue Code, a financial institution is required to file a tax return for a period of less than 12 months, a short period Iowa franchise tax return must be filed for the same period. The delinquency date for the short period return is 45 days after the federal due date not considering any federal extension of time to file.
