Introduction

SECTION 2. BACKGROUND

Internal Revenue Bulletin 2005-18 · 2026-10-03 edition · updated 2026-10-04 · United States

Section 411 requires a qualified plan to meet certain minimum vesting standards. Under § 411(a), an employee’s right to the accrued benefit derived from employer contributions must become nonforfeitable

within a specified period of service, and certain other conditions must also be met. Section 411(a)(3) provides circumstances under which an employee’s benefit is permitted to be forfeited without violating § 411(a). In particular, § 411(a)(3)(B) provides that a right to an accrued benefit derived from employer contributions is not treated as forfeitable solely because the plan provides that the payment of benefits is suspended for such period as the employee is employed, subsequent to the commencement of payment of such benefits—

(i) in the case of a plan other than a multiemployer plan, by the employer who maintains the plan under which such benefits were being paid; and

(ii) in the case of a multiemployer plan, in the same industry, the same trade or craft, and the same geographic area covered by the plan as when such benefits commenced.

This definition of employment for which benefit payments are permitted to be suspended is further described in 29 CFR § 2530.203–3, which interprets section 203(a)(3)(B) of ERISA, the counterpart to § 411(a)(3)(B) of the Code. Employment that satisfies the conditions described in the statute and regulations is referred to as “section 203(a)(3)(B) service.” See 29 CFR § 2530.203–3(c).

Section 411(d)(6)(A) generally provides that a plan is not treated as satisfying the requirements of § 411 if the accrued benefit of a participant is decreased by a plan amendment. Under § 411(d)(6)(B) and regulations thereunder, a plan amendment that has the effect of eliminating or reducing an early retirement benefit, a retirement-type subsidy, or an optional form of benefit, with respect to benefits attributable to service before the amendment, is treated as reducing accrued benefits for any employee who satisfies the pre-amendment conditions for that benefit (either before or after the amendment).

Under § 7805(b)(8), the Commissioner is authorized to prescribe the extent, if any, to which a judicial decision relating to the internal revenue laws is to be applied without retroactive effect.

applicable amendment date of the original amendment, rather than just to benefits that had accrued as of the applicable amendment date, so that the suspension of benefit provisions of the original amendment as reformed only apply to those participants who commence participation after that applicable amendment date.

(3) Effective date and remedial amend- ment period . The reforming amendment must be effective as of a date not later than June 7, 2004. Section 4 provides a remedial amendment period for the reforming amendment.

.03 Payment of retroactive benefits re- quirement . (1) In general . In order for a plan to obtain the treatment provided in section 3.01, the reforming amendment described in section 3.02 must provide for the payment of retroactive benefits (beginning as of June 7, 2004, or such earlier date on which the reforming amendment is made effective pursuant to section 3.02(3)) to an affected plan participant (including any appropriate interest or actuarial increase) with respect to benefits that had accrued as of the applicable amendment date for the original amendment. For purposes of this section 3.03, an affected plan participant means (a) a participant who commenced receipt of benefits and whose benefits were suspended on account of the original amendment or (b) a participant who applied to commence benefits, whose application (including the form of payment) was approved, and whose benefits were suspended before payments commenced.

(2) Effective date for retroactive pay- ment of benefits for affected participants . The plan must provide for the payment of retroactive benefits described in section 3.03(1) effective not later than January 1, 2006. The plan must be in operational compliance with the reforming amendment by January 1, 2006, with respect to benefits payable through December 31, 2005, and must maintain compliance for all periods on or after that date.

.04 Option to commence payment . (1) In general . In order for a plan to obtain the treatment provided in section 3.01, a participant described in section 3.04(2) must be given an opportunity to elect retroactively the commencement of payment of benefits as of the first date on which (a) the reforming amendment is made effective and (b) the participant was eligible

Heinz v. Central Laborers’ Pension Fund, 303 F.3d 802, 805 (7 th Cir. 2002). However, the Court stated:

Nothing we hold today requires the IRS to revisit the tax-exempt status in past years of plans that were amended in reliance on the agency’s representations in its manual by expanding the categories of work that would trigger suspension of benefit payments as to already-accrued benefits. The Internal Revenue Code gives the Commissioner discretion to decline to apply decisions of this Court retroactively. 26 U.S.C. § 7805(b)(8) . . . This would doubtless be an appropriate occasion for exercise of that discretion. Central Laborers’, 124 S.Ct. at 2238, n.4.
