(6) Married taxpayers filing a joint federal return who are allowed a capital loss deduction under section 1211 of the Internal Revenue Code, 26 U.S.C. 1211, and who file separate Montana income tax returns may claim the same amount of the capital loss deduction that is allowed on the federal return. If the allowable capital loss is clearly attributable to one spouse, the loss must be shown on that spouse's return; otherwise, the loss must be split equally on each return.
(7) In the case of passive and rental income losses, married taxpayers filing a joint federal return and who file separate Montana income tax returns are not required to recompute allowable passive losses according to the federal passive activity rules for married taxpayers filing separately under section 469 of the Internal Revenue Code, 26 U.S.C. 469.

(10) A taxpayer receiving retirement disability benefits who has not attained 65 years of age by the end of the tax year and who has retired as permanently and totally disabled may exclude from adjusted gross income up to $100 a week received as wages or payments in lieu of wages for a period during which the employee is absent from work due to the disability. If the adjusted gross income before this exclusion exceeds $15,000, the excess reduces the exclusion by an equal amount. This limitation affects the amount of exclusion, but not the taxpayer's eligibility for the exclusion. If eligible, married individuals shall apply the exclusion separately, but the limitation for income exceeding $15,000 is determined with respect to the spouses on their combined adjusted gross income. For the purpose of this subsection, "permanently and totally disabled" means unable to engage in any substantial gainful activity by reason of any medically determined physical or mental impairment lasting or expected to last at least 12 months.
(11) (a) An individual who contributes to one or more accounts established under the Montana family education savings program or to a qualified tuition program established and maintained by another state as provided by section 529(b)(1)(A)(ii) of the Internal Revenue Code, 26 U.S.C. 529(b)(1)(A)(ii), may reduce adjusted gross income by the lesser of $3,000 or the amount of the contribution. In the case of married taxpayers, each spouse is entitled to a reduction, not in excess of $3,000, for the spouses' contributions to the accounts. Spouses may jointly elect to treat half of the total contributions made by the spouses as being made by each spouse. The reduction in adjusted gross income under this subsection applies only with respect to contributions to an account of which the account owner is the taxpayer, the taxpayer's spouse, or the taxpayer's child or stepchild if the taxpayer's child or stepchild is a Montana resident. The provisions of subsection (1)(e) do not apply with respect to withdrawals of contributions that reduced adjusted gross income.
(b) Contributions made pursuant to this subsection (11) are subject to the recapture tax provided in 15-62-208.
(12) (a) An individual who contributes to one or more accounts established under the Montana achieving a better life experience program or to a qualified program established and maintained by another state as provided by section 529A(e)(7) of the Internal Revenue Code, 26 U.S.C. 529A(e)(7), may reduce adjusted gross income by the lesser of $3,000 or the amount of the contribution. In the case of married taxpayers, each spouse is entitled to a reduction, not to exceed $3,000, for the spouses' contributions to the accounts. Spouses may jointly elect to treat one-half of the total contributions made by the spouses as being made by each spouse. The reduction in adjusted gross income under this subsection (12)(a) applies only with respect to contributions to an account for which the account owner is the taxpayer, the taxpayer's spouse, or the taxpayer's child or stepchild if the taxpayer's child or stepchild is a Montana resident. The provisions of subsection (1)(e) do not apply with respect to withdrawals of contributions that reduced adjusted gross income.
(b) Contributions made pursuant to this subsection (12) are subject to the recapture tax provided in 53-25-118.
(13) (a) A taxpayer may exclude the amount of the loan payment received pursuant to subsection (13)(a)(iv), not to exceed $5,000, from the taxpayer's adjusted gross income if the taxpayer:

(iv) has received a loan payment during the tax year made on the taxpayer's behalf by a loan repayment program described in subsection (13)(b) as an incentive to practice in Montana.
(b) For the purposes of subsection (13)(a), a loan repayment program includes a federal, state, or qualified private program. A qualified private loan repayment program includes a licensed health care facility, as defined in 50-5-101, that makes student loan payments on behalf of the person who is employed by the facility as a licensed health care professional.
(14) Notwithstanding the provisions of subsection (1), adjusted gross income does not include 40% of capital gains on the sale or exchange of capital assets before December 31, 1986, as capital gains are determined under subchapter P. of Chapter 1 of the Internal Revenue Code as it read on December 31, 1986.
(15) A refund received of federal income tax referred to in subsection (1)(b) must be allocated in the following order as applicable:
(a) to federal income tax in a prior tax year that was not deducted on the state tax return in that prior tax year;
(b) to federal income tax in a prior tax year that was deducted on the state tax return in that prior tax year but did not result in a reduction in state income tax liability in that prior tax year; and
(c) to federal income tax in a prior tax year that was deducted on the state tax return in that prior tax year and that reduced the taxpayer's state income tax liability in that prior tax year.
(16) By November 1 of each year, the department shall multiply the amount of pension and annuity income contained in subsection (2)(c)(i) and the federal adjusted gross income amounts in subsection (2)(c)(ii) by the inflation factor for the following tax year, rounded to the nearest $10. The resulting amounts are effective for that following tax year and must be used as the basis for the exemption determined under subsection (2)(c). (Subsection (2)(f) terminates on occurrence of contingency--sec. 3, Ch. 634, L. 1983; subsection (2)(o) terminates on occurrence of contingency--sec. 9, Ch. 262, L. 2001; subsection (2)(t) terminates December 31, 2023--sec. 33, Ch. 457, L. 2015.)
