89A. Multiple employer plans
Publication 6165 — Defined Benefit Listing of Required Modifications and Information Package (LRM) · 2026-10-03 edition · updated 2026-10-04 · United States
Statement of Requirement: Code §I RC 413(c); Treas. Reg. § 1.413-2
Document Provision: _____
(Note to reviewer: A Pre-approved Plan, including a Standardized Plan, may allow for the
plan to be adopted as a multiple employer plan, that is, to be adopted as a non-collectively
bargained single plan benefitting the employees of two or more employers who are not
treated as a single employer under Code §§ IRC 414(b), (c), (m), or (o). To do this, the plan
must include, as an addendum to the adoption agreement, a participation agreement to be
signed by any employer that adopts the plan, other than the “lead” employer that signs the
adoption agreement. The participation agreement must provide that the participating
employer agrees to be bound by the terms of the plan and trust as adopted by the lead
employer, including any amendments thereto and any elections made by the lead
employer, except to the extent the participation agreement allows for, and the
participating employer makes, separate elections with respect to its employees.
The exclusive benefit requirement is applied to a multiple employer plan by treating all employees of all participating employers as if they were the employees of the same
338 | Defined Benefit Plan LRM Package 08/2020 06/2026
employer. In addition, the minimum participation requirements of Code §I RC 410(a) and
the minimum vesting requirements of Code § IRC 411 are applied as if all participating
employers were a single employer, and service for any employer counts as service for all. If
the adoption agreement indicates that Code §I RC 413(c)(4)(A) applies to the plan, the
limitation on accrual and payment of benefits under Code §I RC 436 applies separately to
each employer under the plan as if each such employer maintained a separate plan. If
Code §I RC 413(c)(4)(A) does not apply to the plan, Code §I RC 436 applies as if all
participants in the plan were employed by a single employer.
The limitations of Code §I RC 415 (annual benefits) are applied to the plan as a whole,
rather than on an employer-by-employer basis. Likewise, if a participant is both a 5%
owner and an employee of any participating employer in the year the employee reaches
age 70½, the Applicable Age (under IRC 401(a)(9)(C)(v)), then the employee’s required
beginning date is April 1 of the following year.
Conversely, the minimum coverage requirements of Code §I RC 410(b), the
nondiscrimination requirements of Code §I RC 401(a)(4), the determination of top-heavy
status and minimum contributions under Code §I RC 416, as well as the determination of
highly compensated employees under Code §I RC 414(q), are applied separately, on an
employer-by-employer basis .) ).
Sample plan language:
If elected by the employer in the adoption agreement, the plan may also be adopted, by other
employers that are not aggregated with the employer under Code §§ IRC 414(b), (c), (m), or (o).
Such employers shall adopt the plan by executing a separate participation agreement. In this
case, the Adopting Employer and each participating employer acknowledge that the plan is a
multiple employer plan subject to the specific reporting requirements and rules of Code §I RC
413(c) and the regulations thereunder regarding the qualified status of the plan.
For purposes of plan participation and vesting, the Adopting Employer and all participating
employers shall be considered a single employer. An employee’s service includes all service
with the Adopting Employer or any participating employer (or with any employer aggregated
with the adopting or participating employer under Code §§ IRC 414(b), (c), (m), or (o)). An
employee who discontinues service with a participating employer but then resumes service with
another participating employer shall not be considered to have severed employment.
Except to the extent that the participation agreement allows, and the participating employer
makes, separate elections with respect to its employees, the participating employer shall be
bound by the terms of the plan and trust, including amendments thereto and any elections made
by the Adopting Employer. The limitations under the plan relating to the requirements of Code
§I RC 415 shall be applied to the plan as a whole. The requirements of Code §§ IRC 410(b),
401(a)(4), 414(q), and 416 shall be applied separately to each participating employer. For
purposes of determining a participant’s required beginning date for minimum required
distributions, a participant shall be considered a 5% owner in a year in which the participant is
both a 5% owner and an employee of a participating employer. If the adoption agreement
indicates that Code § IRC 413(c)(4)(A) applies to the plan, the limitation on accrual and
payment of benefits under Code § IRC 436 applies separately to each employer under the plan as
if each such employer maintained a separate plan. If Code § IRC 413(c)(4)(A) does not apply to
339 | Defined Benefit Plan LRM Package 08/2020 06/2026
the plan, Code § IRC 436 applies as if all participants in the plan were employed by a single
employer.
Sample Adoption Agreement Language:
Does the Adopting Employer elect to allow the plan to be adopted by other unrelated employers as a multiple employer plan? (check one):
( ) Yes
( ) No
Participation agreement:
The participation agreement must identify the participating employer and the covered
employees and provide for the participating employer’s signature. The participation agreement
may, but is not required to, provide separate elections with respect to the employees of the
Adopting Employer. In the case of a Standardized Plan, any elections available to a
participating employer must be limited to the elections available to the Adopting Employer.
Thus, the minimum coverage requirements of §I RC 410(b) and the nondiscrimination
requirements of § IRC 401(a)(4) must be satisfied with respect to the employees of the
participating employer regardless of what elections are made in the participation agreement.
(Note to reviewer: The withdrawal of a participating employer from a multiple employer
plan is not a plan termination which allows distributions to be made to participants in the
plan. Instead, a plan termination for distribution purposes occurs when the entire plan
terminates. See Code § IRC 413(c)(3) and Treas. Reg. § 1.413-2(a)(3)(iii). Plan provisions
cannot provide that upon withdrawal of a participating employer, assets will be
distributed as if it were a single employer plan termination. Instead, a withdrawing
employer is required to establish a plan as part of a spinoff transaction within the
meaning of Treas. Reg. § 1.414(l)-1(b)(4) and transfer assets into it; then, if desired,
terminate the spinoff plan.)
