Sec. 4. (a) Every individual (other than a nonresident) who files an individual income tax return and who is entitled to a refund from the department of state revenue because of the overpayment of income tax for a taxable year may designate on the individual's annual state income tax return that either a specific amount or all of the refund to which the individual is entitled shall be paid over to one (1) or more of the funds described in subsection (c). If the refund to which the individual is entitled is less than the total amount designated to be paid over to one (1) or more of the funds described in subsection (c), all of the refund to which the individual is entitled shall be paid over to the designated funds, but in an amount or amounts reduced proportionately for each designated fund. If an individual designates all of the refund to which the individual is entitled to be paid over to one (1) or more of the funds described in subsection (c) without designating specific amounts, the refund to which the individual is entitled shall be paid over to each fund described in subsection (c) in an amount equal to the refund divided by the number of funds described in subsection (c), rounded to the lowest cent, with any part of the refund remaining due to the effects of rounding to be deposited in the nongame fund.

(b) Every husband and wife (other than nonresidents) who file a joint income tax return and who are entitled to a refund from the department of state revenue because of the overpayment of income tax for a taxable year may designate on their annual state income tax return that either a specific amount or all of the refund to which they are entitled shall be paid over to one (1) or more of the funds described in subsection (c). If the refund to which a husband and wife are entitled is less than the total amount designated to be paid over to one (1) or more of the funds described in subsection (c), all of the refund to which the husband and wife are entitled shall be paid over to the designated funds, but in an amount or amounts reduced proportionately for each designated fund. If a husband and wife designate all of the refund to which the husband and wife are entitled to be paid over to one (1) or more of the funds described in subsection (c) without designating specific amounts, the refund to which the husband and wife are entitled shall be paid over to each fund described in subsection (c) in an amount equal to the refund divided by the number of funds described in subsection (c), rounded to the lowest cent, with any part of the refund remaining due to the effects of rounding to be deposited in the nongame fund.

(1) The nongame fund.

(2) The state general fund for exclusive use in funding public education for kindergarten through grade 12.
