ROBS or business stock in a Solo 401(k): Form 5500-EZ hard stop
A hard-stop guide for Solo 401(k) owners with ROBS, employer stock or business-stock facts before preparing Form 5500-EZ.
Summary
A ROBS structure or business-stock holding is not a routine Solo 401(k) Form 5500-EZ packet. Valuation, prohibited-transaction, plan-operation and reporting questions can be material. Use official guidance and a qualified professional before filing.
ROBS and business-stock facts are outside self-serve Form 5500-EZ preparation.

Why business stock changes the filing risk
A simple Solo 401(k) packet usually relies on straightforward year-end account values. Business stock introduces valuation support, corporate records and plan-compliance questions that may affect more than one line on Form 5500-EZ.
ROBS is not a normal brokerage account
A rollover-as-business-startup structure can put retirement-plan assets into employer stock. The annual filing question then sits inside a broader compliance context, not just a form-preparation task.
Where Solo 5500 Desk stops
The product does not value private stock, review ROBS transactions, assess prohibited transactions, validate plan operation or prepare a defense file for IRS/DOL questions.
Common questions
Can Solo 5500 Desk prepare Form 5500-EZ for a ROBS plan?
No. ROBS and business-stock cases are outside scope because they can involve valuation, plan qualification and prohibited-transaction questions.
Is this only a valuation issue?
No. Valuation is important, but ROBS and business-stock arrangements can also involve plan-operation and compliance questions that are not solved by filling a form.
What should I do instead?
Collect plan documents, stock records, valuation support, corporate records and prior filings, then use official guidance or a professional familiar with retirement-plan compliance.
