Sec. 9. (a) The credit provided by this section shall be known as the unified tax credit for the elderly.(b) As used in this section, unless the context clearly indicates otherwise:(1) "Household federal adjusted gross income" means the total adjusted gross income, as defined in Section 62 of the Internal Revenue Code, of an individual, or of an individual and his spouse if they reside together for the taxable year for which the credit provided by this section is claimed.(2) "Household" means a claimant or, if applicable, a claimant and his or her spouse if the spouse resides with the claimant and "household income" means the income of the claimant or, if applicable, the combined income of the claimant and his or her spouse if the spouse resides with the claimant.(3) "Claimant" means an individual, other than an individual described in subsection (c) of this section, who:(A) has filed a claim under this section;(B) was a resident of this state for at least six (6) months during the taxable year for which he or she has filed a claim under this section; and(C) was sixty-five (65) years of age during some portion of the taxable year for which he has filed a claim under this section or whose spouse was either sixty-five (65) years of age or over during the taxable year.(c) The credit provided under this section shall not apply to an individual who, for a period of at least one hundred eighty (180) days during the taxable year for which he has filed a claim under this section, was incarcerated in a local, state, or federal correctional institution.(d) The right to file a claim under this section shall be personal to the claimant and shall not survive his death, except that a surviving spouse of a claimant is entitled to claim the credit provided by this section. For purposes of determining the amount of the credit a surviving spouse is entitled to claim under this section, the deceased spouse shall be treated as having been alive on the last day of the taxable year in which the deceased spouse died. When a claimant dies after having filed a timely claim, the amount thereof shall be disbursed to another member of the household as determined by the commissioner. If the claimant was the only member of his household, the claim may be paid to his executor or administrator, but if neither is appointed and qualified within two (2) years of the filing of the claim, the amount of the claim shall escheat to the state.(e) For each taxable year, subject to the limitations provided in this section, one (1) claimant per household may claim, as a credit against Indiana adjusted gross income taxes otherwise due, the credit provided by this section. If the allowable amount of the claim exceeds the income taxes otherwise due on the claimant's household income or if there are no Indiana income taxes due on such income, the amount of the claim not used as an offset against income taxes after audit by the department, at the taxpayer's option, shall be refunded to the claimant or taken as a credit against such taxpayer's income tax liability subsequently due.(f) The amount of any claim otherwise payable under this section may be applied by the department against any liability outstanding on the books of the department against the claimant, or against any other individual who was a member of his household in the taxable year to which the claim relates.(g) The amount of a claim filed pursuant to this section by a claimant that either (i) does not reside with his spouse during the taxable year, or (ii) resides with his spouse during the taxable year and only one (1) of them is sixty-five (65) years of age or older at the end of the taxable year, shall be determined in accordance with the following schedule:
