SECTION 5. ADOPTION OF INTERIM
Internal Revenue Bulletin 2007-28 · 2026-10-03 edition · updated 2026-10-04 · United States
AND DISCRETIONARY PLAN AMENDMENTS AND EXTENSION OF THE REMEDIAL AMENDMENT PERIOD
.01 Designation of disqualifying provision. Unless otherwise provided in future guidance, in addition to the plan provisions designated as disqualifying provisions subject to the EGTRRA remedial amendment period as described in sections 2.07, 2.08, and 2.09 of this revenue procedure, a plan provision is designated as a disqualifying provision under § 1.401(b)–1(b)(3) if the provision either (1) results in the failure of the plan to satisfy the qualification requirements of the Code by reason of a change in those requirements that is effective after December 31, 2001; or
(2) is integral to a qualification requirement of the Code that has been changed effective after December 31, 2001 but only if the provision is integral to a plan provision that is a disqualifying provision under section 5.01(1) with respect to the plan.
.02 A change in a qualification requirement includes a statutory change or a change in the requirements provided in regulations or other guidance published in the Internal Revenue Bulletin. For purposes of section 5.01, a disqualifying provision includes the absence from a plan of a provision required by or, if applicable, integral to the applicable change in the qualification requirements of the Code. An amendment with respect to a disqualifying provision described in section
5.01(1) or (2) is referred to as an interim amendment for purposes of this revenue procedure.
.03 This section 5.03 extends the remedial amendment period for the disqualifying provisions described below as follows:
(1) The remedial amendment period for any disqualifying provision described in § 1.401(b)–1(b)(1) that would otherwise apply under § 1.401(b)–1 is extended to the end of the applicable remedial amendment cycle described in section 6.01 that includes the date on which the remedial amendment period would otherwise end if the disqualifying provision was a provision of, or absence of a provision from, a new plan and the plan was intended, in good faith, to be qualified. The same extension of the remedial amendment period applies to a disqualifying provision (including a disqualifying provision described in section 5.01) in the case where the employer adopts an amendment to an existing plan (without regard to whether that amendment was required to be adopted) if the amendment was adopted timely and in good faith with the intent of maintaining the qualified status of the plan. The Service will make the final determination in all cases as to whether a new plan or an amendment was adopted with the good faith intention of being qualified or maintaining qualified status.
(2) In addition, the same extension of the remedial amendment period applies to a disqualifying provision described in section 5.01 in the case where the employer (or sponsor or practitioner, if applicable) reasonably and in good faith determines during the period when an interim amendment to reflect a qualification change would otherwise be required under section 5.05 that no amendment is required because the qualification change does not impact provisions of the written plan document. Thus, for example, if a sponsor, practitioner, or employer makes such a determination and the Service in its review of the opinion, advisory, or determination letter application finds that an amendment is required, the plan would still be eligible for the five or six-year remedial amendment cycle to correct the disqualifying provision as described in section 5.01. The Service will make the final determination in all cases as to whether the sponsor’s, practitioner’s or employer’s determination that no interim amendment
2007–28 I.R.B. 60 July 9, 2007
.02 An interim amendment adopted timely and in good faith to correct a disqualifying provision as described in section 5.01 can itself be a disqualifying provision as described in § 1.401(b)–1(b)(1). In this situation, a remedial amendment to correct this second disqualifying provision (that is, the interim amendment which was found to be itself a disqualifying provision) must be adopted by the end of the applicable five or six-year cycle. This remedial amendment will correct both disqualifying provisions.
.03 If as described in section 5.03, a sponsor, practitioner, or employer determined that no amendment was required, but that determination was incorrect, then the sponsor, practitioner, or employer must adopt a remedial amendment to correct the disqualifying provision by the end of the applicable five-year or six-year cycle.
.04 Operational compliance with an amended plan provision that has a retroactive effective date is required for the remedial amendment period for the amended provision to begin as of the retroactive effective date. In the situation where a sponsor, practitioner, or employer timely adopted in good faith an amendment which is not a disqualifying provision as described in § 1.401(b)–1(b)(1) and the sponsor, practitioner, or employer failed to operate the plan according to the terms of the amendment, the employer should correct the operational failure under the Voluntary Correction Program (see Rev. Proc. 2006–27, 2006–1 C.B. 945).
.05 This revenue procedure does not provide relief from the requirements of § 411(d)(6) for any plan amendments including plan amendments adopted as a result of statutory or guidance changes in the plan qualification requirements. Except to the extent permitted under § 411(d)(6) and the regulations thereunder, or under a statutory provision such as section 1107 of PPA ’06, § 411(d)(6) prohibits a plan amendment that decreases a participant’s accrued benefits or that has the effect of eliminating or reducing an early retirement benefit or retirement-type subsidy, or eliminating an optional form of benefit, with respect to benefits attributable to service before the amendment. However, an amendment that eliminates or decreases benefits that have not yet accrued does not violate § 411(d)(6), provided the amendment is
substituted for the language under section 2.05(1) describing the due date (including extensions) for filing the income tax return for the employer’s taxable year. The due date for filing the employer’s tax return in the case of a tax exempt employer that files Form 990–T (Form 990 or Form 990–EZ if no Form 990–T is filed) is the later of the 15 th day of the 10 th month after the end of the employer’s tax year (treating the calendar year as the tax year if the employer does not have a tax year) or the due date for filing the Form 990 series (plus extensions). An employer will not be treated as having obtained an extension of time for filing the Form 990 series unless such extension is actually applied for and granted. The due date for filing the employer’s tax return in the case of a tax exempt employer that is not required to file a Form 990 series return is the 15 th
day of the 10 th month after the end of the employer’s tax year (treating the calendar year as the tax year if the employer does not have a tax year).
.07 Exceptions to section 5.05 amendment adoption deadlines
(1) Section 5.05 applies except when a statutory provision or guidance issued by the Service sets forth an earlier deadline to timely adopt a discretionary amendment with respect to a plan year ( e.g., an amendment to add a qualified cash or deferred arrangement to a profit sharing plan cannot be adopted retroactively) or where a statutory provision or guidance provides another specific deadline for the adoption of a particular type of interim amendment that is earlier or later than the deadlines under section 5.05. For example, section V of Notice 2005–95 lists specific deadlines to amend for specific provisions.
(2) Section 1107 of PPA ’06 is a statutory provision that changes otherwise applicable deadlines under section 5.05. Under section 1107 of PPA ’06, a plan sponsor is permitted to delay adopting a plan amendment pursuant to statutory provisions under PPA ’06 (or pursuant to any regulation issued under PPA ’06) until the last day of the first plan year beginning on or after January 1, 2009 (January 1, 2011 in the case of governmental plans). This amendment deadline applies to both interim and discretionary amendments that are made pursuant to PPA ’06 statutory provisions or any regulation issued under PPA ’06. If section
1107 of PPA ’06 applies to an amendment of a plan, such a plan shall not fail to meet the requirements of Code § 411(d)(6) by reason of such amendment, except as provided by the Secretary of the Treasury. Accordingly, future guidance issued by the Secretary may limit the availability of a retroactive plan amendment under PPA section 1107 in order for the plan to meet the requirements of Code § 411(d)(6). For additional special rules relating to PPA ’06 amendments, see section 4 of this revenue procedure.
.08 For purposes of this revenue procedure, a pre-approved or individually designed plan restatement which is generally effective as of a certain date should not be treated as superseding a previously adopted interim plan amendment that is effective after the restatement’s effective date and that has not been incorporated or reflected in the restatement provided the pre-approved or individually designed plan is operated in a manner consistent with the interim plan amendment. For this purpose, a plan is presumed to be operating in compliance with the interim plan amendments in any case (such as a determination letter application) in which the operation of the plan cannot be determined. This section 5.08 applies for all purposes, including the determination of plan qualification, funding requirements, and deductions.
