Missed MRC 3 years and did not file the 5500 as well

[SSRRS]

Hi,

I hope all the sharp minds of this forums can assist with the following:

We rarely deal with this and with all else going on trying to make sure that not missing any steps, etc.

A DB Plan (with employees) did not make the MRC for 3 years and did not file the 5500 as well for these years.

1. Can they/should they first file the 5500 SFs with the DFVCP, even before they have made up the MRC( plus interest) for these 3 years. 

2. If they file the 5500, will this be a flag and alert about the missed MRC and therefore should not file the 5500s until they have the money to make up the MRC?

3. Should the 5330 be filed before the 5550?

4. If the 5500 can be filed first showing the missed MRC for each year, how much time do they then have to file the 5330?

5. How much time do they have, after filing the 5500 with the DFVCP, to make up the missed MRC for the 3 years?

Meaning can they first file all the 5500s (with the SB each year showing the delinquent contributions), to at least get the 5500s back on track, and then deal with making up the missed MRC and with filing the 5330?

Thank you very much as always!
