I understand that under EPCRS there is a $250 fee for SEP/SIMPLE filings. We have been approached with a situation as follows:

Company has a SEP plan; only the owners participate and they max out
Company adopted a SIMPLE IRA plan 3-5 years ago; only the employees are in it and the company does the matching contribution approach
Owners also apparently contribute to IRAs….

Could we file this situation under EPCRS using the $250 fee?
Could this be filed anonymously?
Any suggestions as to the best way to handle this?
