Q. Will an extension of time to file Form OP-424 or to pay the business entity tax be granted to a business entity?

A. No extension of time will be granted to file Form OP-424.  The return is due on or before the fifteenth day of the fourth month following the end of the business entity’s taxable year. A business entity’s taxable year is its taxable year for federal income tax purposes. If your business reports its income on the calendar year, the due date for Form OP-424 is April 15th of the following year.  If a business entity had a short taxable year for federal income tax purposes, its Form OP-424 would be due on or before the fifteenth day of the fourth month following the end of its short taxable year.
