SECTION 5. WHAT IS THE
Internal Revenue Bulletin 2006-1 · 2026-10-03 edition · updated 2026-10-04 · United States
GENERAL SCOPE OF A DETERMINATION LETTER?
.02 For the procedures for obtaining letter rulings, determination letters, etc., on matters within the jurisdiction of the Division Counsel/Associate Chief Counsel (Tax Exempt and Government Entities), or within the jurisdiction of other offices of Chief Counsel, see Rev. Proc. 2006–1, page 1, this Bulletin.
Scope of this section .01 This section delineates, generally, the scope of an employee plan determination letter. It identifies certain qualification requirements, relating to nondiscrimination, that are considered by the Service in its review of a plan only at the election of the applicant. This section also identifies certain qualification requirements that are not considered by the Service in its review of a plan and with respect to which determination letters do not provide reliance. This section applies to all determination letters other than letters issued in response to an application filed on Form 6406, Short Form Application for Determination for Minor Amendment of Employee Benefit Plan ; letters relating to the qualified status of group trusts; and letters relating solely to the requirements of § 420, regarding the transfer of assets in a defined benefit plan to a health benefit account described in § 401(h). For additional information pertaining to the scope of reliance on a determination letter, see sections 8, 9 and 21 of this revenue procedure, and section 19 of Rev. Proc. 2005–16.
Scope of determination letters .02 In general, employee plans are reviewed by the Service for compliance with the form requirements (that is, those plan provisions that are required as a condition of qualification under § 401(a)). In addition, as described below, certain nondiscrimination requirements are considered if the applicant specifically requests that they be considered. For terminating plans, the requirements are those that apply as of the date of termination. See Rev. Proc. 2005–66 for further details on the scope of the Service’s review of determination letter applications.
2006–1 I.R.B. 211 January 3, 2006
Nondiscrimination in amount requirement
Minimum coverage and § 401(a)(26) participation requirements
Nondiscriminatory current availability requirement
Other nondiscrimination requirements
Reliance conditioned on retention of information
.03 Unless the applicant elects otherwise, a plan will not be reviewed for, and a determination letter may not be relied on with respect to, whether a plan satisfies one of the safe harbors or the general test for nondiscrimination in amount of contributions or benefits requirements under § 1.401(a)(4)–1(b)(2) of the Income Tax Regulations.
.04 Unless the applicant elects otherwise, a plan will not be reviewed for, and a determination letter may not be relied on with respect to, the minimum coverage requirements of § 410(b). If the applicant demonstrates that the plan satisfies the coverage requirements of § 410(b), the determination letter may also be relied on with respect to the participation requirements of § 401(a)(26).
.05 If the applicant demonstrates that the plan satisfies the coverage requirements of § 410(b), the determination letter may also be relied on as to whether the plan satisfies the nondiscriminatory current availability requirements of § 1.401(a)(4)–4(b) with respect to those benefits, rights, and features that are currently available (within the meaning of § 1.401(a)(4)–4(b)(2)) to all employees in the plan’s coverage group. The plan’s coverage group consists of those employees who are treated as currently benefiting under the plan (within the meaning of § 1.410(b)–3(a)) for purposes of demonstrating that the plan satisfies the minimum coverage requirements of § 410(b). Applications will not be reviewed for, and determination letters may not be relied on with respect to, whether the plan satisfies the requirements of § 1.401(a)(4)–4(b) with respect to any benefit, right, or feature other than the ones described above, except those that are specified by the applicant and for which the applicant has provided information relevant to the determination.
.06 An applicant may also ask that the review of its plan consider certain other nondiscrimination requirements which are described in Schedule Q (Form 5300), such as whether a definition of compensation satisfies § 414(s).
.07 A favorable determination letter may be relied on with respect to whether a plan satisfies a coverage or nondiscrimination requirement only if the application, demonstrations and other information submitted to the Service in support of a favorable determination is retained by the applicant.
Effective availability requirement .08 In no event will any plan be reviewed to determine, and a determination letter may not be relied on with respect to, whether any benefit, right, or feature under the plan satisfies the effective availability requirement of § 1.401(a)(4)–4(c).
Other limits on scope of determination letter
.09 Determination letters may generally be relied on with respect to whether the timing of a plan amendment (or series of amendments) satisfies the nondiscrimination requirements of § 1.401(a)(4)–5(a) of the regulations, unless the plan amendment is part of a pattern of amendments that significantly discriminates in favor of highly compensated employees. A favorable determination letter does not provide reliance for purposes of § 404 and § 412 with respect to whether an interest rate (or any other actuarial assumption) is reasonable. Furthermore, a favorable determination letter will not constitute a determination with respect to the use of the substantiation guidelines contained in Rev. Proc. 93–42, 1993–2 C.B. 540, e.g., a determination letter will not consider whether data submitted with an application is substantiation quality. Lastly, a favorable determination letter will not constitute a determination with respect to whether any requirements of § 414(r), relating to whether an employer is operating qualified separate lines of business, are satisfied. However, if an employer is relying on § 414(r) to satisfy the minimum coverage or § 401(a)(26) participation requirements, and the applicant so requests, a determination letter will take into account whether the plan satisfies the nondiscriminatory classification test of § 410(b)(5)(B). In this case, if the requirements of § 410(b) or § 401(a)(26) are to be applied on an employer-wide basis under the special rules for employer-wide plans, a determination letter will take into account whether the requirements of the applicable special rule set forth in § 1.414(r)–1(c)(2)(ii) or § 1.414(r)–1(c)(3)(ii) are met.
