(1)  an administrative proceeding of a local, state, or federal regulatory agency;  or
(2)  a judicial proceeding arising from an administrative proceeding of a local, state, or federal regulatory agency.
(b)  A final determination that affects the amount of liability of a tax imposed by this title shall be reported to the comptroller before the expiration of 120 days after the day on which the determination becomes final.  The report must include a detailed statement of the reasons for the difference in tax liability as required by the comptroller.
(c)  Notwithstanding the expiration of a period of limitation provided in this title, the comptroller may assess and collect or bring suit for the collection of any tax deficiency, including penalties and interest, resulting from a final determination at any time before the expiration of one year after:
(1)  the later of the day the report is required to be filed as provided by Subsection (b) or the day the report is received;  or
(2)  the day the final determination is discovered, if a report is not filed.
(d)  If a final determination results in the taxpayer having overpaid the amount of tax due the state, the taxpayer may file a claim for refund with the comptroller for the amount of the overpayment before the first anniversary of the date the final determination becomes final.  If the comptroller assesses tax by issuing a deficiency determination within the period provided by Subsection (c), the taxpayer may file a claim for refund for an amount of tax that has been found due in a deficiency determination before the 180th day after the deficiency determination becomes final, but the claim is limited to the items and the tax payment period for which the determination was issued.
(e)  This section does not shorten any period of limitation elsewhere provided in this title.
(f)  In this section:
(1)  "Federal regulatory agency" includes the United States Internal Revenue Service.
(2)  "Administrative proceeding" includes an audit by the United States Internal Revenue Service.
