1. Any registered caregiver who meets the requirements of this section shall be eligible for a shared care tax credit in an amount not to exceed five hundred dollars to defray the cost of caring for an elderly person. In order to be eligible for a shared care tax credit, a registered caregiver shall:

(1) Care for an elderly person, age sixty or older, who:

(a) Is physically or mentally incapable of living alone, as determined and certified by his or her physician licensed pursuant to chapter 334, or by the department staff when an assessment has been completed for the purpose of qualification for other services; and

(b) Requires assistance with activities of daily living to the extent that without care and oversight at home would require placement in a facility licensed pursuant to chapter 198; and

(c) Under no circumstances, is able or allowed to operate a motor vehicle; and

(d) Does not receive funding or services through Medicaid or social services block grant funding;

(2) Live in the same residence to give protective oversight for the elderly person meeting the requirements described in subdivision (1) of this subsection for an aggregate of more than six months per tax year;

(3) Not receive monetary compensation for providing care for the elderly person meeting the requirements described in subdivision (1) of this subsection; and

(4) File the original completed and signed physician certification for shared care tax credit form or the original completed and signed department certification for shared care tax credit form provided for in subsection 2 of section 192.2010 along with such caregiver’s Missouri individual income tax return to the department of revenue.

2. The tax credit allowed by this section shall apply to any year beginning after December 31, 1999.

3. Any rule or portion of a rule, as that term is defined in section 536.010, that is created under the authority delegated in sections 192.2000 to 192.2020 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. All rulemaking authority delegated prior to August 28, 1999, is of no force and effect and repealed. Nothing in this section shall be interpreted to repeal or affect the validity of any rule filed or adopted prior to August 28, 1999, if it fully complied with all applicable provisions of law. 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, 1999, shall be invalid and void.

4. Any person who knowingly falsifies any document required for the shared care tax credit shall be subject to the same penalties for falsifying other tax documents as provided in chapter 143.
