Form 5500 under ERISA
Form 5500 (officially the Annual Return/Report of Employee Benefit Plan) is the primary annual reporting form required under the Employee Retirement Income Security Act of 1974 (ERISA). It is part of ERISA’s broader reporting and disclosure framework (primarily under Title I and Title IV) and the Internal Revenue Code.1
The U.S. Department of Labor (DOL), Internal Revenue Service (IRS), and Pension Benefit Guaranty Corporation (PBGC) jointly developed the Form 5500 Series so that employee benefit plans can satisfy annual reporting obligations in a single filing.2
Purpose
The form serves three main roles:
- Compliance tool — It helps regulators verify that plans are operated and managed according to ERISA standards.
- Disclosure document — Plan participants and beneficiaries can access key information about their plan’s finances and operations.
- Research and data source — Federal agencies, Congress, and the private sector use the aggregated data to analyze employee benefit, tax, and economic trends.3
It reports the plan’s qualification status, financial condition, investments, operations, participant counts, and service-provider details.
Who Must File
Any administrator or sponsor of a pension or welfare benefit plan covered by ERISA generally must file, unless an exemption applies. Filing is typically required when the plan:
- Has 100 or more participants at the beginning of the plan year, or
- Holds assets in a trust (regardless of participant count).
Exemptions commonly apply to:
- Unfunded or fully insured welfare plans with fewer than 100 participants.
- Governmental, church, or certain foreign plans.
- One-participant (owner-only) plans in most cases.4
Variants in the Form 5500 Series
| Form | Used For | Key Eligibility Notes |
|---|---|---|
| Form 5500 | Most large plans (≥100 participants) | Full financial schedules + independent audit usually required |
| Form 5500-SF | Small plans (<100 participants) | Simplified filing; must meet specific investment/audit waiver rules |
| Form 5500-EZ | One-participant plans or certain foreign plans | Owner-only or partner/spouse plans; filed electronically or on paper in limited cases |
Additional schedules (e.g., Schedule H for finances, Schedule C for service providers, Schedule R for retirement plan info, actuarial schedules, etc.) are attached depending on the plan type.2
Filing Requirements and Deadlines
- Electronic filing only — All Form 5500, 5500-SF, and most 5500-EZ filings must be submitted through the DOL’s EFAST2 system (using approved software or the web-based iFile tool). Paper filing is generally not allowed.1
- Deadline — The last day of the seventh month after the plan year ends (e.g., July 31 for a calendar-year plan). An extension can be requested using Form 5558.
- Public availability — Most filings are publicly viewable on the DOL’s EFAST2 website (except one-participant plans filed via EFAST2).
In short, Form 5500 is the cornerstone of ERISA’s transparency and oversight system. It ensures that employee benefit plans remain accountable to participants, regulators, and the public while providing valuable nationwide data on retirement and welfare benefits.
