An eligible participant in a retirement plan, as defined by section 1526 of the Taxpayer Relief Act of 1997, 26 U.S.C. 415, may purchase service credit without regard to the limitations of section 415(c)(1) of the Internal Revenue Code under the Montana statutes in effect on August 5, 1997.(4)(a) For the purpose of calculating the maximum contribution under section 415 of the Internal Revenue Code, the definitions of "compensation", "wages", and "salary" include the amount of any elective deferral, as defined in section 402(g) of the Internal Revenue Code, or any contribution that is contributed or deferred by the employer at the election of the member and that is not includable in the gross income of the member by reason of section 125, 132(f), 403(b), or 457 of the Internal Revenue Code. Any changes in the maximum limits under section 415 of the Internal Revenue Code must be applied prospectively.(b) For limitation years beginning after December 31, 2000, compensation must also include any elective amounts that are not able to be included in the gross income of the member by reason of section 132(f)(4) of the Internal Revenue Code.(c) For limitation years beginning on and after September 1, 2009, compensation for the limitation year must also include compensation paid by the later of 2.5 months after a member's severance from employment or the end of the limitation year that includes the date of the member's severance from employment if:(i) the payment is regular compensation for services during the member's regular working hours or compensation for services outside the member's regular working hours, such as overtime or shift differential, commissions, bonuses, or other similar payments, and absent a severance from employment, the payments would have been paid to the member while the member continued in employment with the employer; or(ii) the payment is for unused accrued sick, vacation, or other leave that the member would have been able to use if employment had continued.(d) For limitation years beginning on or after September 1, 2009, a member's compensation for purposes of this section may not exceed the annual limit under section 401(a)(17) of the Internal Revenue Code.(e) Beginning January 1, 2009, to the extent required by section 414(u)(12) of the Internal Revenue Code, 26 U.S.C. 414(u)(12), a member receiving from an employer differential wage payments as defined under section 3401(h)(2) of the Internal Revenue Code, 26 U.S.C. 3401(h)(2), must be treated as employed by that employer. The differential wage payments must be treated as compensation for purposes of applying the limits on annual additions under section 415(c) of the Internal Revenue Code, 26 U.S.C. 415(c). This provision must be applied to all similarly situated employees in an equivalent manner.Amended by Laws 2015, Ch. 210, Sec. 25, eff. 7/1/2015, and applicable retroactively, within the meaning of 1-2-109, to differential wage payments made on or after 1/1/2009.En.
