SCOPE

.01 General Limits on Opinion Letters

  • Opinion letters will be issued only to sponsors or M&P mass submitters. Opinion letters constitute determinations as to the qualification of the plans as adopted by particular employers only under the circumstances, and to the extent, described in section 19. In the case of prototype plans, opinion letters do not constitute rulings or determinations as to the exempt status of related trusts or custodial accounts.

.02 Nonapplicability of the Procedure to IRAs and SEPs - Opinion letters will not be issued under this revenue procedure for prototype plans intended to meet the requirements for individual savings programs or simplified employee pension programs under § 408 (see Rev. Proc. 87–50, 1987–2 C.B. 647, Rev. Proc. 97–29, 1997–1 C.B. 698, and Rev. Proc. 98–59, 1998–2 C.B. 727). .03 Areas Not Covered by Opinion Letters - Opinion letters will not be issued for:

(1) Multiemployer plans and multiple employer plans;

(2) Union plans (This does not preclude an M&P plan from covering employees of the employer who are included in a unit covered by a collective bargaining agreement or the adoption of an M&P plan pursuant to such agreement as a single employer plan that covers only employees of the employer.);

(3) Stock bonus plans; (4) Employee stock ownership plans; (5) Pooled fund arrangements contemplated by Rev. Rul. 81–100, 1981–1 C.B. 326; (6) Annuity contracts under § 403(b); (7) Cash balance plans or other defined benefit plans under which the test for nondiscrimination under § 401(a)(4) is made by reference to contributions rather than benefits;

(8) Plans described in § 414(k) (relating to a defined benefit plan that provides a benefit derived from employer contributions that is based partly on the balance of the separate account of a participant);

(9) Target benefit plans, other than plans which, by their terms, satisfy each of the safe harbor requirements described in § 1.401(a)(4)–8(b)(3)(i), as well as the additional rules in § 1.401(a)(4)–8(b)(3)(ii) through (vii);

(10) Defined benefit plans that provide for employee contributions;

(11) Plans that would not satisfy the qualification requirements except as governmental plans as described in § 414(d);

(12) Church plans described in § 414(e) that have not made the election provided by § 410(d);

(13) Plans under which the § 415 limitations are incorporated by reference;

(14) Plans that incorporate the ADP test under § 401(k)(3) or the ACP test under § 401(m)(2) by reference;

2004-18 I.R.B. 868 May 3, 2004

In addition, each M&P mass submitter must submit a list to Employee Plans Determinations of all sponsors that have adopted a word-for-word identical plan of the M&P mass submitter and a copy of any plan that contains minor modifications. Each M&P mass submitter and sponsor of a non-mass submitter plan must also furnish Employee Plans Determinations with a copy of all amendments subsequently approved as to form by the Service. Copies of word-for-word identical plans of M&P mass submitters should not be submitted to Employee Plans Determinations.
