Isn't one advantage signing after 12/31 not filing 5500 form? Actuarial certifications still need to be done
For example (extreme one):
S-corp (with employees) decides to start one on 9/14, signs and funds on 9/15. If wanted to file 5500 form, has to file on 9/15 (special extension) as no 5558 to extend to 10/15. Of course, it is assumed that s-corp tax filing is on extension.
Full disclosure, not a fan of above but happened once or twice😁
CuseFan has made good points. But more and more I think and encourage, the clients should start the plans after year end as the census data would be final and available and also allow a better design than making one up during the year as census changes all the time.
Just saying it.
