  The amount of taxes due on any return which has been filed as required by this chapter shall be determined and assessed within thirty-six (36) months from the date the return was filed except as otherwise provided in this section and Section 27-65-55.   When an examination of a taxpayer's records to verify returns made under this chapter has been initiated and the taxpayer notified of the examination, either by certified mail or personal delivery by an agent of the commissioner, within the thirty-six-month examination period provided for in subsection (1) of this section, the determination of the correct tax liability shall be made by the commissioner within one (1) year after the expiration of the thirty-six-month examination period; however, this limitation shall not apply:   To any tax period for which the taxpayer failed to file a return, in which case the tax, including any applicable penalties and interest, may be assessed by the commissioner at any time and the tax, penalties and/or interest so assessed may be collected by the commissioner as otherwise provided by law.   In the case of a false or fraudulent return with the intent to evade tax. In such a case the commissioner is authorized to compute, determine, and assess at any time the estimated amount of tax due on the return, including any applicable penalties and interest, from any information in his or her possession, and after the tax, penalties and/or interest are assessed, to collect them as otherwise provided by law.   In the case of an agreement in writing entered into by the commissioner and the taxpayer, made prior to the expiration of the applicable time periods provided for in subsections (1) and (2) of this section, consenting to the examination of a return. In such a case the determination of a tax overpayment or deficiency and/or the issuance of an assessment may be made within the agreed upon period. The period agreed upon may be extended by subsequent agreements in writing made before the expiration of the previously agreed upon period.   In a case in which a taxpayer requests an extension of time for filing any return required by this chapter, and the request is granted. In such a case the limitation of time for examining the return and determining any tax overpayment or assessing any tax deficiency from the return shall be extended for a like period.     A taxpayer may apply to the commissioner for revision of the tax assessed against him or her, or paid by him or her, at any time within thirty-six (36) months from the date of the assessment or from the date the return was filed. Unless a claim for credit or refund is filed by the taxpayer within thirty-six (36) months from the time the return was filed or assessment made, no credit or refund shall be allowed.   Taxpayers shall keep and maintain an accurate and complete set of records and other information sufficient to allow the department to determine the correct amount of tax due. The records and other information shall be open and available for inspection by the department upon request at a reasonable time and location. Refusal or delay by the taxpayer to provide documentation for examination upon the department's request shall result in an assessment being made from any information available, which shall be prima facie correct.
