An appeal of the assessment is pending before the taxation board of review or the tax appeal court, beginning on the date the notice of appeal is filed and concluding on the date a final decision is issued or the case is withdrawn or dismissed.

(b) Limitations on credit or refund. Claim for credit or refund of an overpayment of any tax imposed by this chapter shall be filed by the taxpayer or employer within three years from the time the return was filed or from the due date prescribed for the filing of the return, or within two years from the time the tax was paid, whichever is later. For the purposes of this section, taxes paid before the due date of the return shall be deemed to have been paid on the due date of the return determined without regard to any extensions.

(1) If the claim was filed by the taxpayer during the three-year period prescribed in this subsection, the amount of the credit or refund shall not exceed the portion of the tax paid within the period, immediately preceding the filing of the claim, equal to three years plus the period of any extension of time for filing the return.

(2) If the claim was not filed within the three-year period, the amount of the credit or refund shall not exceed the portion of the tax paid during the two years immediately preceding the filing of the claim.

(3) If no claim was filed, the credit or refund shall not exceed the amount which would be allowable under paragraph (1) or (2), as the case may be, if the claim was filed on the date the credit or refund is allowed.

(c) Exceptions; fraudulent return or no return. In the case of a false or fraudulent return with intent to evade tax or liability, or of a failure to file return, the tax or liability may be assessed or levied at any time; provided that the burden of proof with respect to the issues of falsity or fraud and intent to evade tax shall be upon the State.

(d) Extension by agreement. Where, before the expiration of the time prescribed in subsection (a) for the assessment, levy, and collection of the tax or liability, or in subsection (b) for the credit or refund of an overpayment, both the department and the taxpayer or employer have consented in writing to its assessment or levy after that date, the tax or liability may be assessed or levied or the overpayment, if any, may be credited at any time prior to the expiration of the period previously agreed upon. The period so agreed upon may be extended by the subsequent agreements in writing made before the expiration of the period previously agreed upon.

(e) Overpayment of carrybacks. If an overpayment results from a net operating loss carryback, the statute of limitations in subsections (a) and (b) shall not apply. The overpayment shall be credited within three years of the due date prescribed for filing the return (including extensions thereof) for the taxable year of the net operating loss, or the period agreed to under subsection (d) with respect to the taxable year, whichever expires later.
