(1) The tax return shall be filed and the total amount of the franchise tax shall be due on the fifteenth day of the third month after the end of the taxable year. No extension of time to pay the tax shall be granted. If the Tax Commissioner determines that the amount of tax can be computed from available information filed by the financial institutions with either state or federal regulatory agencies, the Tax Commissioner may, by regulation, waive the requirement for the financial institutions to file returns.

If the filing of a return is waived by the Tax Commissioner, the payment of the tax shall be considered the filing of a return for purposes of sections 77-2714 to 77-27,135.

(3) No refund of the tax imposed by section 77-3802 shall be allowed unless a claim for such refund is filed within ninety days of the date on which (a) the tax is due or was paid, whichever is later, (b) a change is made to the amount of deposits or the net financial income of the financial institution by a state or federal regulatory agency, or (c) the Nebraska Investment Finance Authority issues an eligibility statement to the financial institution pursuant to the Affordable Housing Tax Credit Act.
