Listen to what austin3515 says about how your software might react to a report that would be logically internally inconsistent.
Eighteen or as few as 15 business days remain before October 15. (Federal, State, NYSE, and religions’ days vary.)
Most CPA firms with a capacity for employee-benefit plan audits long ago stopped accepting engagements for 2023 audits.
But with a relationship plea and a rush fee, a plan’s administrator still might engage an independent qualified public accountant.
About what Form 5500 report (if any) a TPA might prepare (or decline to assemble), a few suggestions:
1. Read, carefully, your service agreement to know your rights, obligations, and conditions.
2. Even if it is the plan’s administrator that must sign the report, don’t assist a false or misleading statement.
3. Be careful with anything your client might alter or misuse, especially if it has your name associated with it.
4. CYA—Cover Your Assets.
This is not advice to anyone.
