True or false; a final Form 5500-EZ is always required for terminated plans with a one-participant plan?

A final Form 5500-EZ is indeed always required for terminated one-participant plans. This form serves as a report regarding the financial condition, investments, and operations of a retirement plan, and it must be filed to provide the IRS with necessary information about the plan's status after termination.

For one-participant plans, the requirement to file a final Form 5500-EZ applies regardless of the plan’s asset size or the number of participants involved. This emphasizes the importance of closing out the plan properly to comply with regulations and avoid potential penalties. The filing of this form is essential not only for compliance with IRS rules but also for ensuring that the participant's retirement benefits are accurately reported and managed upon plan termination.

Other factors, such as the number of participants or asset thresholds, do not alter the requirement for filing the form in the case of a one-participant plan's termination, which reinforces the necessity and uniformity of the filing requirement in these situations.
