.01 Applications for determination letters under § 401(a) or § 403(a) that are filed with the Service on or after June 26, 2000, for individually-designed plans, including volume submitter plans, will be reviewed taking into account all the changes in the qualification requirements made by GUST, including those changes made by SBJPA that are first effective in plan years beginning after December 31, 1998, unless the sponsor asks the Service to limit the extent to which the plan is reviewed for GUST, as described below. (Determination letters that take into account all the GUST changes are referred to in this revenue procedure as “GUST II letters.” Except in the case of terminating plans, the review of applications for determination letters for M&P plans will take into account the GUST changes only to the extent that the M&P plan sponsor has amended the plan for GUST and received a favorable opinion letter.
.02 Until further notice, sponsors of individually-designed plans, including volume submitter plans, will continue to have the option of limiting the extent to which their plans are reviewed for GUST by requesting either a GUST I letter or a preGATT letter, rather than a GUST II letter. The sponsor should make this request in a cover letter with the application. (This option does not apply to applications for determination on plan termination.) Under this option, the sponsor will need to submit another application and pay another
user fee to obtain a GUST II letter.
.04 In general, plans must be restated when they are submitted for GUST II determination letters. For this purpose, submission of a working copy of the plan in a restated format will suffice. A plan is generally exempt from the requirement to restate, however, if there have been fewer than four consecutive amendments since the plan was last restated, excluding amendments making only nonsubstantive plan changes, the plan has a favorable TRA ‘86 determination letter, and the plan meets either of the following conditions:
1 The plan is a defined contribution plan under which the only contributions are nonelective employer contributions; or 2 The plan has a favorable GUST I determination letter and is not adding provisions designed to satisfy the safe harbor requirements of § 401(k)(12) or § 401(m)(11). The Service nevertheless reserves the right to require restatement of a plan or submission of a working copy of a plan in a restated format in any case in which this is determined to be necessary.
.05 In general, Form 6406, Short Form Application for Determination for Minor Amendment of Employee Benefit Plan, may not be used to apply for either a GUST I or a GUST II letter. However, if use of Form 6406 is not otherwise precluded by section 11 of Rev. Proc. 2000–6, Form 6406 may be used to apply for a GUST II letter for a defined contribution plan with a favorable
.03 Because the proposed regulations under § 411(d)(6) may not be relied upon prior to finalization, the proposed regulations will not be taken into account by the Service for purposes of issuing determination letters. Until such regulations are finalized, the Service will not issue a favorable determination letter for a plan that is amended to eliminate or reduce benefits in a manner that is not permitted under regulations now in effect. Therefore, sponsors who are considering submitting determination letter applications before the proposed regulations under § 411(d)(6) are finalized should also be aware that they may have to submit another application and pay another user fee if they wish to adopt plan amendments as a result of the final regulations.
GUST I letter which does not include provisions designed to satisfy the safe harbor requirements of § 401(k)(12) or § 401(m)(11). In this case, the application should include a cover letter indicating the application is for a GUST II letter. The Service reserves the right to require the filing of a Form 5300 series application in any case in which it determines that the use of Form 6406 is inappropriate.
.06 The Service will attempt to contact each plan sponsor who has a Form 5300 determination letter application being reviewed by a determination letter specialist on June 26, 2000, to determine if the sponsor wishes to convert the application to a GUST II application. The Service will continue to process each other pending application in accordance with the procedures in effect prior to June 26, 2000.
