I had a solo 401(k) plan held at one institution and then transferred it to a new institution, specifying it as a restatement. Unfortunately, I realize now that I incorrectly incremented the sequence number, rather than using the same one. I've contacted the new institution to ask them to correct the sequence number, but I was wondering if there was anything more I need to do? (I have not yet heard back from the institution know if they'll push back on updating it in their own records.)
Note that no 5500 has ever been filed for this plan, as the assets are below the threshold.
I'm referring back to this prior thread which indicated that using a new sequence number technically creates a new plan. Unfortunately, I didn't read it beforehand.
