§11-24-20. Report of change in federal taxable income.
If the amount of a taxpayer's federal taxable income reported on its federal income tax return for any taxable year is changed or corrected by the United States internal revenue service or other competent authority, or as the result of a renegotiation of a contract or subcontract with the United States, the taxpayer shall report such change or correction in federal taxable income within ninety days after the final determination of such change, correction or renegotiation, or as otherwise required by the tax commissioner, and shall concede the accuracy of such determination or state wherein it is erroneous. Any taxpayer filing an amended federal income tax return shall also file within ninety days thereafter an amended return under this article, and shall give such information as the tax commissioner may require. The tax commissioner may by regulation prescribe such exceptions to the requirements of this section as he deems appropriate.
