Let's say you have more than one Solo 401(k). Separately, the balance in either plan is not above $250k but combined the plan balances are above $250k. Do I need to file a form 5500 for both plans?
The IRS has addressed this contingency. If a plan meets all the requirements for filing Form 5500-SF, and its total assets (either alone or in combination with one or more one-participant plans maintained by the employer) exceed $250,000 at the end of the plan year, Form 5500-SF must be filed for each of the employer's one-participant plans including those with less than $250,000 in assets for the plan year.
Rocket Dollar uses the Form 5500-SF when assisting customers because it can be filed electronically.
Both are similar documents that are shorter and easier to complete than the basic form 5500, which is usually used for Employer 401(k) plans with multiple common-law employees.
