SECTION 21. WHAT

Internal Revenue Bulletin 2015-1 · 2026-10-03 edition · updated 2026-10-04 · United States

EFFECT WILL AN EMPLOYEE PLAN DETERMINATION LETTER HAVE?

Scope of reliance on determination letter

Sections 13 and 14 of Rev. Proc. 2015–4 applicable

Effect of subsequent publication of revenue ruling, etc.

Determination letter does not apply to taxability issues

.07 Where the applicant has requested EP Rulings and Agreements to seek technical advice on the applicability of § 7805(b) relief, the applicant’s administrative remedies will not be considered exhausted until the Office of Associate Chief Counsel has had a reasonable time to act upon the request for technical advice.

.08 The step described in section 20.02(3) will not be available or necessary with respect to any issue on which technical advice has been obtained from the Office of Associate Chief Counsel.

.01 A determination letter issued pursuant to this revenue procedure contains only the opinion of the Service as to the qualification of the particular plan involving the provisions of §§ 401 and 403(a) and the status of a related trust, if any, under § 501(a). Such a determination letter is based on the facts and demonstrations presented to the Service in connection with the application for the determination letter and may not be relied upon after a change in material fact or the effective date of a change in law, except as provided. The Service may determine, based on the application form, the extent of review of the plan document. Failure to disclose a material fact or misrepresentation of a material fact adversely affects the reliance that would otherwise be obtained through the issuance by the Service of a favorable determination letter. Similarly, failure to accurately provide any of the information called for on any form required by this revenue procedure may result in no reliance. Applicants are advised to retain copies of all supporting data submitted with their applications. Failure to do so may limit the scope of reliance.

.02 Except as otherwise provided in this section, determination letters are governed, generally, by the provisions of sections 13 and 14 of Rev. Proc. 2015–4.

.03 The prior qualification of a plan as adopted by an employer will not be considered to be adversely affected by the publication of a revenue ruling, a revenue procedure, or an administrative pronouncement within the meaning of § 1.6661–3(b)(2) of the regulations where:

(1) The plan was the subject of a favorable determination letter and the request for that letter contained no misstatement or omission of material facts;

(2) The facts subsequently developed are not materially different from the facts on which the determination letter was based;

(3) There has been no change in the applicable law; and

(4) The employer that established the plan acted in good faith in reliance on the determination letter.

However, all such plans must be amended to comply with the published guidance for subsequent years, in accordance with the rules set forth in Rev. Proc. 2007–44. See, in particular, Part II of that revenue procedure.

.04 While a favorable determination letter may serve as a basis for determining deductions for employer contributions thereunder, it is not to be taken as an indication that contributions are necessarily deductible as made. This latter determination can be made only upon an examination of the employer’s tax return, in accordance with the limitations, and subject to the conditions of, § 404.
