What Is Form 5500-EZ?
Form 5500-EZ is an annual IRS filing used by certain one-participant retirement plans and certain foreign plans. It is most commonly relevant to owner-only retirement plans, including solo 401(k) plans, when filing requirements apply.
The form is part of retirement-plan reporting, not an individual income-tax return. It helps satisfy annual reporting obligations for plans that are not subject to the standard ERISA Title I Form 5500 reporting requirements.
Key Takeaways
- Form 5500-EZ is generally used by one-participant retirement plans and certain foreign plans.
- Owner-only plans may need to file once plan assets exceed the applicable filing threshold or when the plan terminates.
- Some filers may need to file electronically depending on IRS e-filing rules.
- Missing required filings can create penalties, so plan sponsors should track annual filing status.
Who Usually Encounters It
A one-participant plan generally covers only the business owner and the owner's spouse, or partners and their spouses in a partnership. A solo 401(k) owner may not think of the plan as a formal retirement plan at first, but once assets grow, annual reporting can become part of the administrative calendar.
The filing requirement depends on the plan, year-end assets, termination status, and current IRS instructions. The threshold and filing mechanics can change, so the current IRS instructions should be checked before deciding that no filing is due.
Filing Situation | Practical Question |
|---|---|
Owner-only plan | Does the plan meet Form 5500-EZ filing rules for the year? |
Plan termination | Is a final return required? |
Electronic filing rules | Must the sponsor file through EFAST2? |
Late filing | Are IRS correction or penalty relief options available? |
Small-Business Planning Context
Form 5500-EZ is one reason a solo 401(k) is not entirely hands-off. The plan can be powerful for owner retirement savings, but the owner is also the plan sponsor and must keep records, follow plan terms, monitor contribution limits, and file required forms.
Business owners should coordinate the form with their tax preparer, plan provider, or third-party administrator rather than assuming the investment custodian automatically handles every filing obligation.
The Bottom Line
Form 5500-EZ is a retirement-plan reporting form for certain owner-only and foreign plans. It matters because a solo 401(k) or similar plan can create annual filing duties once the plan reaches the filing threshold or terminates.
