Form 5500 Series (5500, 5500-SF & 5500-EZ)

What is the Form 5500 Series?

The Form 5500 Series is an annual reporting requirement for many employee benefit plans. It is used to report plan details, participant information, and financial data.

  • Form 5500 is the standard annual return/report for many employee benefit plans
  • Form 5500-SF is the short form for eligible small plans
  • Form 5500-EZ is for one-participant plans (generally owner-only or owner & spouse)

Which form you file depends on your plan type and eligibility.

Key Concept (Choose the Right Form)

Use these three simple explanations to decide what you should file.

Form 5500-EZ

File 5500-EZ if the plan covers only the owner (or owner & spouse). This is a one-participant plan.

Form 5500-SF

File 5500-SF only if your plan covers employees, generally has fewer than 100 participants, and meets all short-form eligibility requirements.

Form 5500

File Form 5500 for employee plans that are not eligible for Form 5500-SF and generally for plans with 100 or more participants.

Important: “Fewer than 100 participants” does not automatically mean “no filing.” It generally affects which form an employee plan may qualify to use, such as Form 5500-SF.

Who Needs to File?

You may need to file a Form 5500 Series return if you sponsor or administer an employee benefit plan. The correct form depends on your plan type.

Employee benefit plans include retirement plans (such as 401(k), profit-sharing, or pension plans) and welfare plans (such as health, dental, vision, or life insurance).

Form 5500

Employee plans that are not eligible for Form 5500-SF and generally plans with 100 or more participants.

Form 5500-SF

Form 5500-SF is available only to eligible small plans (generally fewer than 100 participants) that meet all short-form eligibility requirements.

Form 5500-EZ
