@dmertz I have taken a look at 5500-EZ, it does look simple (i.e., total plan assets at beginning and end of year). I want to simply fill out the paper form for my solo 401K and mail it. Is there any way to be certain that the IRS has processed it? I will send it certified mail with tracking to ensure that it gets there but would like some indication that the IRS has OK'd and recorded it. The penalties by the IRS and DOL look quite stiff for late filing (i.e., $250/day).
