I have a new client who is a single member LLC. We filed Form 2553 in September 2021 and indicated that the client was unaware of the filing requirement for form 2552. We have not heard anything back from the IRS. 

I tried to extended the return just now and got an error. The return is finished. I was only extending because his personal is not finished and wanted the client to only have to come in one time to sign.

Is your suggestion to prepare a paper return (1120s) and attach 2552 with FILED PURSUANT TO REV. PROC. 2013-30 on the top of it?  Would mail before 3/15/22.

Any thoughts or suggestions is greatly appreciated!
