DC Master Trust and Form 5500

Good morning,

I haven't worked on plans part of a master trust(MT) for awhile

2 DC plans 001 & 333 are part of MT

No audit was done for MT but Form 5500 filed

Instead, each plan filed their own detailed Sch H with audit reports and auditor mentioned in 2022 audit notes about the plans being part of MT

Is this ok?

In the past, I have filed the audit with MT Form 5500 and the plans would just list their $ in MT on Sch H. 

I'm also questioning the use of plan #333? this is a union 401(k) plan- no other employers

Much thanks,

Lexy

The audit is for the plan, and so it gets attached to the Plan's 5500. The Master Trust Investment Account filing is considered part of the Form 5500 for the Plan, but it is not itself required to attach an audit report.
