(1) Although a single adoption agreement may be made available to different categories of eligible employers, the adoption agreement must require the adopting employer to show its status as an eligible employer by indicating whether the employer is:

(a) a government-sponsored educational organization described in § 170(b)(1)(A)(ii) (a “public school”);

(b) a tax-exempt organization described in § 501(c)(3) which is exempt from tax under § 501(a);

(c) an employer of a minister described in § 414(e)(5)(A); or

(d) a minister described in § 414(e)(5)(A).

(2) The adoption agreement must require the adopting employer to show its status with respect to the nondiscrimination requirements in § 1.403(b)–5 by indicating whether the plan is:

(a) a governmental plan of a public school;

(b) a governmental plan of a tax-exempt organization described in § 501(c)(3);

(c) a plan of an employer that is a Church or QCCO; or

(d) a plan (other than a plan described in (a), (b), or (c)) of an employer that is a tax-exempt organization described in § 501(c)(3).

(3) The adoption agreement must allow the adopting eligible employer to add overriding plan language if necessary to satisfy § 415 because of the required aggregation of multiple plans. See section 9.01.

(4) The adoption agreement must contain a dated employer signature line. The eligible employer must sign the adoption agreement when it first adopts the plan and must complete and sign a new adoption agreement if the plan has been restated. In addition, the eligible employer must complete a new signature page if it modifies any prior elections or makes new elections in its adoption agreement. The signature requirement may be satisfied by an electronic signature that reliably authenticates and verifies the adoption of the adoption agreement, or restatement, amendment or modification thereof, by the eligible employer.

(5) The adoption agreement must state that it is to be used only with one specific basic plan document, and must identify that document.

(6) The adoption agreement must contain a cautionary statement to the effect that the failure to properly fill out the adoption agreement may result in failure of the plan to satisfy the requirements of § 403(b). The Service expects that § 403(b) prototype plan documents will be written in a manner designed to assist adopting eligible employers in the correct completion of the adoption agreement.

(7) The adoption agreement must include the prototype sponsor’s name, address, and telephone number (or a space for the address and telephone number of the prototype sponsor’s authorized representative) for inquiries by adopting eligible employers regarding the adoption of the plan, the meaning of plan provisions, or the effect of the opinion letter.

.04 The adoption agreement of every nonstandardized § 403(b) prototype plan must satisfy the following additional requirements:

(1) The adoption agreement must state that, unless the plan is a governmental plan, a Church, or a QCCO, the plan must satisfy the requirements of §§ 401(a)(4) and 410(b) with respect to nonelective contributions under the plan on a continuing basis.

(2) The adoption agreement must state that the opinion letter may not be relied upon with respect to whether the plan satisfies the requirements of §§ 401(a)(4) and 410(b).
