WILLAN EMPLOYEE PLAN DETERMINATION LETTER HAVE?

Scope of reliance on .01 A determination letter issued pursuant to this revenue procedure contains only the determination letter 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. For example, a determination letter issued pursuant to this revenue procedure may not be relied upon after a significant change in plan coverage resulting from the operation of the plan. 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 may adversely affect the reliance which 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 demonstrations and supporting data submitted with their applications. Failure to do so may limit the scope of reliance.

Effect of determination letter .02 Determination letters issued on minor amendments to plans and trusts under this on minor plan amendment revenue procedure will merely express an opinion whether the amendment, in and of itself, affects the existing status of the plan’s qualification and the exempt status of the related trust. In no event should such a determination letter be construed as an opinion on the qualification of the plan as a whole and the exempt status of the related trust as a whole.

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

Unless specifically stated otherwise in the revenue ruling or in other published guidance of general applicability, the conforming amendment to an individually designed plan must be adopted before the end of the first plan year that begins after the revenue ruling, revenue procedure, or administrative pronouncement is published in the Internal Revenue Bulletin and must be effective, for all purposes, not later than the first day of the first plan year beginning after the revenue ruling is published. For the rule as to the conforming amendment to an M&P plan and a regional prototype plan, see section 14 of Rev. Proc. 89–9 and Rev. Proc. 89–13, as modified by Rev. Proc. 90–21, sections 8.03–8.08 of Rev. Proc. 91–66, and Rev. Proc. 92–41.
