1. Notwithstanding the provisions of any other law to the contrary, with respect to taxes administered by the department of revenue under this chapter and chapters 143, 144, and 147, an amnesty from the assessment or payment of all penalties, additions to tax, and interest shall apply with respect to unpaid taxes or taxes due and owing reported and paid in full from September 1, 2015, to November 30, 2015, regardless of whether previously assessed, except for penalties, additions to tax, and interest paid before September 1, 2015. The amnesty shall apply only to tax liabilities due or due but unpaid on or before December 31, 2014, and shall not extend to any taxpayer who at the time of payment is a party to any criminal investigations or to any civil or criminal litigation that is pending in any court of the United States or this state for nonpayment, delinquency, or fraud in relation to any state tax imposed by this state.

2. Upon written application by the taxpayer, on forms prescribed by the director of revenue, and upon compliance with the provisions of this section, the department of revenue shall not seek to collect any penalty, addition to tax, or interest that may be applicable. The department of revenue shall not seek civil or criminal prosecution for any taxpayer for the taxable period for which the amnesty has been granted unless subsequent investigation or audit shows that the taxpayer engaged in fraudulent or criminal conduct in applying for amnesty.

3. Amnesty shall be granted only to those taxpayers who have applied for amnesty within the period stated in this section, who have filed a tax return for each taxable period for which amnesty is requested, who have paid the entire balance by November 30, 2015, and who agree to comply with state tax laws for the next eight years from the date of the agreement. No taxpayer shall be entitled to a waiver of any penalty, addition to tax, or interest under this section unless full payment of the tax due is made in accordance with rules established by the director of revenue.

4. All taxpayers granted amnesty under this section shall in good faith comply with this state’s tax laws for the eight years following the date of the amnesty agreement. If any such taxpayer fails to comply with all of this state’s tax laws at any time during the eight years following the date of the agreement, all penalties, additions to tax, and interest that were waived under the amnesty agreement shall become due and owing immediately.

5. If a taxpayer is granted amnesty under this section, such taxpayer shall not be eligible to participate in any future amnesty for the same type of tax.

6. If a taxpayer elects to participate in the amnesty program established in this section as evidenced by full payment of the tax due as established by the director of revenue, that election shall constitute an express and absolute relinquishment of all administrative and judicial rights of appeal. No tax payment received under this section shall be eligible for refund or credit.

7. Nothing in this section shall be interpreted to disallow the department of revenue to adjust a taxpayer’s tax return as a result of any state or federal audit.

8. All tax payments received as a result of the amnesty program established in this section, other than revenues earmarked by the Constitution of Missouri, this state’s statutes, or subsection 9 of this section, shall be deposited in the tax amnesty fund created in subsection 9 of this section. Moneys in the fund shall only be expended for the following except that any excess moneys not used for such purposes shall be deposited into the state general revenue fund:

(1) An increase in the rate of reimbursement to MO HealthNet providers for the fiscal year ending June 30, 2016, above the rate in effect for the fiscal year ending June 30, 2015; and

(2) An increase in the number of adults receiving dental coverage under MO HealthNet in the fiscal year ending June 30, 2016, above the number of adults receiving dental coverage in the fiscal year ending June 30, 2015.

9. There is hereby created in the state treasury the “Tax Amnesty Fund”, which shall consist of money collected under this section. The state treasurer shall be custodian of the fund and may approve disbursements from the fund in accordance with sections 30.170 and 30.180. Upon appropriation, money in the fund shall be used solely for the purpose provided in subsection 8 of this section. Any moneys remaining in the fund at the end of the biennium shall revert to the credit of the general revenue fund. The state treasurer shall invest moneys in the fund in the same manner as other funds are invested. Any interest and moneys earned on such investments shall be credited to the fund.

10. The department of revenue may enter into an agreement with a third-party vendor to provide collection services for eligible delinquent tax liabilities that the department has undertaken to collect under this section, and to assist with the administration of the amnesty program under which contingency and other fees may be payable to such approved vendor out of the revenues from the amnesty program.

11. The department may promulgate rules or issue administrative guidelines as are necessary 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, 2015, shall be invalid and void.

12. This section shall expire on December 31, 2023.
