What Is a Wrap Document?

A wrap document for a retirement plan is a single, umbrella document that “wraps around” the various plan materials and insurance contracts an employer already uses for its 401(k) or other benefit plans. Its main purpose is to make sure the plan meets the disclosure and reporting requirements under the Employee Retirement Income Security Act (ERISA) — specifically, to create one unified plan document and Summary Plan Description (SPD).

Here’s how it works and why it matters:

1. What a Wrap Document Does

Many retirement plans — especially 401(k)s — are built from a combination of documents: the recordkeeper’s plan document, the trust agreement, and the service provider contracts. However, these documents alone often don’t satisfy all ERISA disclosure and reporting requirements.
A wrap document “wraps around” those materials, adding the missing ERISA provisions and converting the plan into a single, compliant “employee benefit plan” under ERISA.

In short, the wrap document:

• Identifies the plan sponsor, administrator, and fiduciaries.

• Describes eligibility, participation, and claims procedures.

• Incorporates underlying plan materials (like the adoption agreement and trust).

• Fulfills ERISA’s SPD requirement, often doubling as both the plan document and the SPD.

2. Why Employers Use It

Without a wrap document, employers may need to file multiple Form 5500s — one for each plan or vendor contract. A wrap document lets employers combine all their retirement or welfare benefit components under a single “wrap plan,” simplifying compliance and reporting.
For example, an employer might use one wrap document to cover all 401(k) investment options offered through multiple recordkeepers, allowing a single annual filing and a single SPD for employees.

3. Fiduciary Importance

A wrap document also helps clarify fiduciary responsibilities. It designates who has authority over plan decisions, who serves as the “plan administrator,” and how service providers are monitored. This is critical because, under ERISA, the plan sponsor (employer) is legally responsible for acting in the best interest of plan participants — and courts have been increasingly strict in enforcing those duties.

4. Relationship to Fiduciary Governance

Just as health plans are now subject to heightened fiduciary scrutiny under the Consolidated Appropriations Act (CAA) of 2021, retirement plans remain under close Department of Labor oversight. A well-drafted wrap document provides the structure employers need to demonstrate fiduciary prudence, document their processes, and ensure consistency between the plan’s operation and its governing terms.

5. Key Takeaway

A wrap document doesn’t change the benefits or investment options in a retirement plan — it simply brings everything together into one compliant, well-documented package. Think of it as a fiduciary shield and organizational tool: it simplifies administration, clarifies roles, and ensures ERISA compliance.
