The return need not reflect any income tax liability owed by the taxpayer.

(2) A claim for the credit may be filed quarterly for refund of the state sales and use taxes paid, either directly or indirectly, after the filing of the income tax return for the taxable year in which the credit was first allowed.

(3) The credit may be used to obtain a refund of state sales and use taxes paid before the end of the taxable year for which the credit was allowed, except that the amount refunded under this subsection shall not exceed the amount of the state sales and use taxes paid, either directly or indirectly, by the taxpayer on the qualifying investment.

(4) For purposes of subsections (2) and (3) of this section, the taxpayer shall be deemed to have paid indirectly any state sales or use taxes paid by a contractor on building materials annexed to an improvement to real estate built for the taxpayer. The contractor shall certify to the taxpayer the amount of the Nebraska state sales and use taxes paid on the building materials, or the taxpayer, with the permission of the Tax Commissioner and a certification from the contractor that Nebraska state sales and use taxes were paid on all building materials, may presume that fifty percent of the cost of the improvement was for building materials annexed to real estate on which the tax was paid.

(5) No claim for refund of sales and use taxes under this section may be filed prior to January 1, 1989.

The changes made by Laws 2003, LB 608, shall not preclude a taxpayer from receiving the tax incentives earned prior to January 1, 2004.
