Solo 401(k) plans were a great opportunity for owner-employees to offer a plan for themselves (as well as their spouse).
The only problem is that they can be a disaster because of the lack of support most custodians give to their plan. Many of these plans may have missing plan documents, a lack of a signed document, and a lack of a restatement. Some of these plans could also have an issue regarding missing Form 5500s if the plan has more than $250,000 in assets and the solo owner didn’t realize there was a requirement.
If you have a solo 401(k) plan with zero help, it does make sense to have your plan looked at.
