  If for any year the amount of federal net income tax payable, of a credit claimed or carried forward, of a net operating loss carried forward or of a capital loss carried forward of any taxpayer as reported to the internal revenue service is changed or corrected by the internal revenue service or other officer of the United States, such taxpayer shall report such changes or corrections to the department within 90 days after its final determination and shall concede the accuracy of such determination or state how the determination is erroneous. Such changes or corrections need not be reported unless they affect the amount of net tax payable under this chapter, of a credit calculated under this chapter, of a Wisconsin net operating loss carried forward, of a Wisconsin net business loss carried forward or of a capital loss carried forward under this chapter. Any taxpayer submitting an amended return to the internal revenue service, or to another state if there has been allowed a credit against Wisconsin taxes for taxes paid to that state, shall also file, within 90 days of such filing date, an amended return if any information contained on the amended return affects the amount of net tax payable under this chapter of a credit calculated under this chapter, of a Wisconsin net operating loss carried forward, of a Wisconsin net business loss carried forward or of a capital loss carried forward under this chapter.
