What is form 5500-EZ for the Solo 401k?

Solo 401k form 5500-EZ is an information-only form that is completed and filed by 401k plan administrators. As your own Solo 401k plan administrator, completing and filing this form is part of your responsibility in running your Solo 401k plan.

From the IRS: “Form 5500-EZ is used by one-participant plans and foreign plans that are not subject to the requirements of section 104(a) of the Employee Retirement Income Security Act of 1974 (ERISA) and that do not choose to file Form 5500-SF electronically to satisfy certain annual reporting and filing obligations imposed by the Code.” (Source)

In other words, the 5500-EZ form is used to report your Solo 401k annual holdings.

2017 Form 5500-EZ

When is form 5500-EZ due?

The 5500-EZ  is due by July 31st but only if your Solo 401k plan had $250,000 or more in assets at the end of the calendar year last yeat.

Example: If on December 31st, 2017 your Solo 401k had $250,000 or more in total assets, then you would file your form 5500-EZ by  July 31st, 2018. If you just set up your plan this year, you don’t need to file your 5500-EZ until next year. The 5500-EZ is filed for the previous calendar year.

Who must file form 5500-EZ?

The 5500-EZ must be filed if your Solo 401k had more than $250,000 in total assets during previous calendar year or if last year was the final year of your plan.

If you have less than $250,000 in plan assets, you don’t need to file the 5500-EZ.

If last year was the FINAL year of your Solo 401k (you closed down your business or cancelled your plan completely), then you MUST file a 5500-EZ, even if you had less than $250,000 in total plan assets.

How do I know my total Solo 401k plan asset value?

To determine if you need to file form 5500-EZ, add up all the assets in your Solo 401k plan (including liquid cash and inveestments owned by the Solo 401k). This can include (but is not limited to):

  1. Bank accounts owned by the Solo 401k
  2. Brokerage accounts owned by the Solo 401k
  3. Investments such as cryptocurrency (you can get your end of year statement from the exchange where you purchased your crypto),
  4. Real estate (generally a broker opinion letter or appraisal is desired to get your accurate property price – if this is your first year of ownership, you can generally use the price listed on your closing documents).
  5. Private lending where the Solo 401k was the borrower

Helpful Hint: Make sure you have the Solo 401k Adoption Agreement provided to you when you set up your plan with Nabers Group, and a record of your cumulative plan assets before you get started.

Part I Annual Return Identification: Suggestions and Guidelines

Part I Guidelines

Most plan years are from January 1st to December 31st. This information can be found on page 3 of the Adoption Agreement, item 6, “Plan Year.”

• Check box A(1) if this is the first filing for this plan. This checkbox is only for your very first 5500-EZ.

• Check box A(2) if you are filing an amended Form 5500-EZ to correct errors and/or omissions in a previously filed annual return.

• Check box A(3) if you closed your Solo 401k and distributed all the assets.

• Check box A(4) if this form is filed for a period of less than 12 months. Show the dates at the top of the form – this will not typically apply to most Solo 401k accountholders

If none of these situations apply to you, do not check any boxes. If this your 2nd, 3rd, 4th (etc) year filing the 5500-EZ, you don’t need to check any box in section 1A.

Part II Basic Plan Information: Suggestions and Guidelines

Part II Guidelines

Helpful hint: If this isn’t your first year filing form 5500-EZ and your business and/or plan information hasn’t changed, you can generally input the same information as last year.

Use the Solo 401k Adoption Agreement provided to you by the Nabers Group team to complete the plan information for questions 1a-3c.

NOTE: If your adopting employer is a Sole Proprietorship, you must obtain an EIN from the IRS. Social Security Numbers are NOT allowable on the 5500-EZ.

If you restated your plan or changed your Solo 401k adopting employer since your last 5500-EZ filing, and your old plan had a different name, you’ll need to complete questions 4a-4d as applicable.

If you restated your plan to the Solo 401k by Nabers Group and you already had a tax ID number assigned to your trust, only input the information here if your plan name and plan number have changed with the restatement.

If you restated your plan to the Solo 401k by Nabers Group and you didn’t have a tax ID number assigned to your trust, you’ll probably input your new plan name and plan number here.


For example: if you previously had an individual 401k plan with a brokerage house (e.g. Fidelity, Schwab, Merrill Lynch, etc), or another document provider, you most likely restated your plan to the Solo 401k by Nabers Group when you set up your plan with us. If your plan name and number changed with the restatement, input your old plan name and plan number in section 4b and 4c, so the IRS can keep track that this is the same business filing form 5500-EZ for its retirement plan, and that the documents have simply restated and with a new name/plan number.

Similarly, if you changed the Adopting Employer connected to the plan since your last 5500-EZ filing, and your company EIN has changed, you should complete this section. If only the Employer and/or employer identification number (EIN) has changed, update line 4a and 4b (and leave 4c and 4d blank).

If nothing has changed on your plan and your employer identification number, employer information, plan name and plan number remain the same – leave section 4a-4d blank.

Enter your participant information in questions 5a-5c. Unless you got married, divorced or fired your spouse from working in your business, the number of participants at the beginning and end of a plan year will generally be the same.

Part III Financial Information: Total up your cumulative plan assets, funds, and liabilities

Part III Guidelines

In this section, you’ll enter your total plan assets at the beginning and end of the calendar year. The easiest way to do this is to tally your cumulative assets as of January 1st last year and then add them up again for December 31st last year.

If you are completing this filing because last year was the final year for your Solo 401k, the total plan assets may be less than $250,000

Enter “Total plan liabilities”. From the IRS instructions on completing the 5500-EZ: “Liabilities include but are not limited to benefit claims payable, operating payables, acquisition indebtedness, and other liabilities. Do not include the value of future distributions that will be made to participants.” (Source).

Enter “Net plan assets” for the beginning and end of the year. You can find this number by subtracting the assets and liabilities at the beginning and end of the year, and enter in the total amount. 

DEFINITION by the IRS of Total Plan Assets:

‘“Total plan assets” include rollovers and transfers received from other plans, unrealized gains and losses such as appreciation/depreciation in assets. It also includes specific assets held by the plan at any time during the plan year (for example, partnership/joint venture interests, employer real property, real estate (other than employer real property), employer securities, loans (participant and non-participant loans), and tangible personal property). Enter the total amount of plan assets at the beginning of the plan year in column (1). Do not include contributions designated for the 2017 plan year in column (1).” (Source)

For questions 7a-7c, enter your information for how much you contributed to your Solo 401k plan last year.

Line 7a: Enter the total employer cash contributions for the year. There is no employer match with the Solo 401k. The employer profit-sharing contributions are based on a percentage of earned income of the business above and beyond the employee elective deferral limit.

Line 7b: Enter the total employee elective deferral cash contributions for the year. Employee elective deferrals can be either pre-tax(non-Roth) or after tax (Roth).

Line 7c: Enter the amount of all transfers or rollovers received during the calendar year from other plans valued on the date of contribution. This does not include income or contributions. Any income put directly into the plan is a contribution, not a rollover.

Rollovers don’t count toward contribution limits though they do count toward total plan assets. If you roll in $250k or any amount that raises your plan assets to $250,000 or more, you must file a 5500-EZ.

Part IV Plan Characteristics: Suggestions and Guidelines

Part IV Guidelines

Plan characteristics codes can be found on page 6 of the 5500-EZ instructions:

Codes applicable to the most Solo 401k plans:

2E – profit sharing
2J – section 401(k) feature
3B – plan covering self-employed individuals.
3D – pre-approved pension plan

It may also be the opinion of your tax advisor that the following codes are applicable to your Solo 401k depending on your use of the plan:

2R – participant-directed brokerage accounts 
2S – plan provides for automatic enrollment in plan that has employee contributions deducted from payroll.

For example, if you and your spouse opened a Fidelity non-prototype retirement account as a brokerage account for your Solo 401k plan, you most likely will include “2R” as each brokerage account is “participant-directed” according to Fidelity’s guidelines.

Part V Compliance and Funding Questions: Suggestions and Guidelines

Part V Guidelines

For this section, check “Yes” on question 9 if the Solo 401k had any outstanding participant loans. You must also check “Yes” if you had an already existing outstanding loan during the reporting calendar year. Make sure to enter the amount outstanding as of the end of the calendar year for your 5500-EZ filing.

For line 10, you can generally check “No” since the Solo 401k by Nabers Group is a define contribution, not a defined benefit plan.

The Solo 401k by Nabers Group affords you complete flexibility in your contributions, without a minimum funding requirement. Therefore, line 11 can be “no” and the remainder of this section is not applicable. 

Sign and date the bottom of the form and you’re done!

  1. Hi I need to file a form 5500 EZ final return for year 2016. I had an S corp which I closed on December 31, 2019. I had a self employed 401K plan for myself from March 2015 to November 2016. The total plan assets at the time of closure were $112000. I did not know that I had to file a final 5500 EZ when the plan was closed. I received a reminder notice cp214 that return was due. The return seems fairly straight forward but I don’t want to miss something and have to redo it for some small mistake. Can you recommend a CPA who can complete this form. I live in Mt. Laurel, NJ 08054

  2. I can’t find Form 5500 EZ (2017), anywhere (except for a poor quality image file). Other years, yes. Help!

    1. Hi Brooke, by now the IRS has released the 2018 form so you won’t be able to locate the 2017 form. If you didn’t file the 2017 form on time, most CPAs will recommend you enter the 5500-EZ Late Filers Penalty Relief program. You’ll use this year’s form (2018) and submit to the IRS. We strongly recommend you work with a CPA who is familiar with the Solo 401k plan, if you missed the filing deadline. This way you have great support in getting the form filed correctly.
