1. A self-employed taxpayer, as such term is used in the federal internal revenue code, who is otherwise ineligible for the federal income tax health insurance deduction under Section 162 of the federal internal revenue code shall be entitled to a credit against the tax otherwise due under this chapter, excluding withholding tax imposed by sections 143.191 to 143.265, in an amount equal to the portion of such taxpayer’s federal tax liability incurred due to such taxpayer’s inclusion of such payments in federal adjusted gross income. To be eligible for a credit under this section, the self-employed taxpayer shall have a Missouri income tax liability, before any other tax credits, of less than three thousand dollars. The tax credits authorized under this section shall be nontransferable, nonrefundable, and shall not be carried back or forward to any other tax year. A self-employed taxpayer shall not claim both a tax credit under this section and a subtraction under section 143.113 for the same tax year.

2. The director of the department of revenue shall promulgate rules and regulations to administer 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, 2007, shall be invalid and void.

3. Pursuant to section 23.253 of the Missouri sunset act:

(1) The provisions of this section shall sunset automatically on December 31, 2028, unless reauthorized by an act of the general assembly; and

(2) If such program is reauthorized, this section shall sunset automatically December thirty-first six years after the effective date of the reauthorization of this section; and

(3) This section shall terminate on September first of the calendar year immediately following the calendar year in which the program authorized under this section is sunset; and

(4) The provisions of this subsection shall not be construed to limit or in any way impair the department’s ability to redeem tax credits authorized on or before the date the program authorized pursuant to this section expires, or a taxpayer’s ability to redeem such tax credits.
