Rolled a Solo 401(k) to an IRA: do I need a final Form 5500-EZ?
What Solo 401(k) owners should check after rolling all plan assets to an IRA or another retirement account.
Summary
If a Solo 401(k) rolled all assets to an IRA or another eligible retirement account and the plan ended, the sponsor should evaluate a final Form 5500-EZ. The filing question is about the plan's final year, not only the account's year-end balance. Rollover tax treatment is outside a packet tool.
A complete rollover can create final-return facts even below $250,000.

Separate rollover tax treatment from filing facts
A rollover can be tax-free and still leave a filing task. The Form 5500-EZ packet looks at plan identity, assets, distributions or transfers, final-year status, and filing method.
Documents to collect
Collect the custodian transfer confirmation, IRA receiving statement, final Solo 401(k) account statement, plan termination notes, prior-year ending balance, and any communication from a provider or trustee.
When to stop
Stop for late filings, amended returns, IRS notices, uncertain rollover treatment, missing records, loan defaults, non-owner employees, controlled groups, or hard-to-value assets.
Common questions
Does an IRA rollover close the plan automatically?
Not necessarily. You need plan-level facts: whether all assets left, whether the plan was terminated, and whether a final return is required.
Can this product decide if my rollover was tax-free?
No. It organizes Form 5500-EZ packet facts; rollover validity and tax treatment require official instructions or professional review.
