Yes. As the plan administrator of your Solo 401(k), you are required to provide an annual statement to each plan participant. Because you are both the administrator and the participant, this is an internal document you prepare for your own records. There is no prescribed format, but certain information should be included.
Unlike a brokerage IRA, your Solo 401(k) has no third-party institution tracking and reporting on your investments. You are the fund manager, the plan administrator, and the participant. That means if you were audited, became incapacitated, or passed away, there would be no institutional record of what your plan holds or what it is worth. A well-maintained annual statement fills that gap.
The statement also serves practical purposes. It documents the plan value needed for Form 5500-EZ, supports Required Minimum Distribution calculations, provides the plan summary a lender may request during a mortgage application, and gives your beneficiaries a clear picture of what the plan holds.
A Solo 401(k) plan statement does not need to be elaborate, but it should document the following:
Your plan name and address of record. Your name as the plan participant, with a separate statement or sub-section for each participant if your spouse also holds an account. The tax treatment of each account, with tax-deferred and Roth accounts reported separately. The statement date and the period it covers.
For each asset held in the plan, document the account or asset description, beginning value, ending value, and the participant account it belongs to. Summarize additions to the plan including contributions, rollovers, and participant loan repayments. Summarize any distributions taken during the year. If the plan has an outstanding participant loan, include the loan balance, interest rate, monthly payment, and maturity date.
The final figure is ending total plan value, which is the sum of all participant account values across all assets and cash held by the plan.
If your plan has more than one participant, or if you hold both tax-deferred and Roth accounts, each participant account must be tracked and reported separately. When a plan asset is purchased using funds from multiple accounts, document the ownership split at the time of purchase and maintain that split consistently in future statements. You cannot reassign ownership interests between accounts after the fact.
Prepare the statement annually as of December 31. This is the date used for Form 5500-EZ reporting and for Required Minimum Distribution calculations.
Is there a required format for the statement?
No. The IRS does not specify a format. A spreadsheet, a word processing document, or any other organized format that captures the required information is acceptable. What matters is completeness and accuracy, not presentation.
Do I need to file the statement with anyone?
No. The annual plan statement is an internal document. Retain it with your plan records. You may be asked to produce it if your plan is audited or if you apply for a mortgage or other financing.
What if I have assets that are difficult to value precisely?
Use the best reasonable estimate available and document your methodology. For most alternative assets, realtor comparables, open note balances, or sponsor-provided values are acceptable. Formal appraisals are required only when a taxable event such as Required Minimum Distributions, a Roth conversion, or in-kind distribution is involved.
