(1) If a taxpayer files with the department of revenue a federal adjustments report or an amended Missouri tax return as required within the period provided under subsections 2 to 9 of this section, the department of revenue shall assess any amounts, including taxes, interest, additions to tax, and penalties arising from such federal adjustments if the department of revenue issues a notice of the assessment to the taxpayer no later than:

The estimated tax payments shall be credited against any tax liability ultimately found to be due to Missouri and shall limit the accrual of further interest on such amount. If the estimated tax payments exceed the final tax liability and interest ultimately determined to be due, the taxpayer shall be entitled to a refund or credit for the excess, provided the taxpayer files a federal adjustments report or claim for refund or credit of tax under section 143.781 or 143.821 no later than one year following the final determination date.
12. Except for final federal adjustments required to be reported for federal purposes under 26 U.S.C. Section 6225(a)(2), a taxpayer may file a claim for refund or credit of tax arising from federal adjustments made by the IRS on or before the later of:
(1) The expiration of the last day for filing a claim for refund or credit of Missouri tax under section 143.801, including any extensions; or
(2) One year from the date a federal adjustments report required under subsections 2 to 9 of this section, as applicable, was due to the department of revenue, including any extensions provided under subsection 13 of this section.
­­The federal adjustments report shall serve as the means for the taxpayer to report additional tax due, report a claim for refund or credit of tax, and make other adjustments resulting from adjustments to the taxpayer's federal taxable income.
13. (1) Unless otherwise agreed in writing by the taxpayer and the department of revenue, any adjustments by the department or by the taxpayer made after the expiration of the appropriate limitations period provided under section 143.711 or 143.801 shall be limited to changes to the taxpayer's tax liability arising from federal adjustments.
(2) For purposes of compliance with this section, the time periods provided for in this chapter may be extended:
(a) Automatically, upon written notice to the department of revenue, by ninety days for an audited partnership or tiered partner which has one hundred or more direct partners; or
(b) By written agreement between the taxpayer and the department of revenue.
(3) Any extension granted under this subsection for filing the federal adjustments report extends the last day prescribed by law for assessing any additional tax arising from the adjustments to federal taxable income and the period for filing a claim for refund or credit of taxes under section 143.781 or 143.821.
14. The department of revenue shall promulgate rules to implement the provisions of this section. Any rule or portion of a rule, as that term is defined in section 536.010, that is created under the authority delegated in this section shall become effective only if it complies with and is subject to all of the provisions of chapter 536 and, if applicable, section 536.028. This section and chapter 536 are nonseverable and if any of the powers vested with the general assembly pursuant to chapter 536 to review, to delay the effective date, or to disapprove and annul a rule are subsequently held unconstitutional, then the grant of rulemaking authority and any rule proposed or adopted after August 28, 2020, shall be invalid and void.
15. The provisions of this section shall apply to any adjustments to a taxpayer's federal taxable income or federal adjusted gross income with a final determination date occurring on or after January 1, 2021.
