I need to file two 5500-ez via the IRS relief program dating back 7 & 8 years when my solo/individual 401k exceeded $250k (I was ignorant of the requirement to do this). The $500 penalty per submission is a bargain compared to the alternative.
What I don't understand is why the Department of Labor DFVC program doesn't also cover solo 401k's 5500-ez submissions - won't the paper submission of the delinquent 5500-ez via the IRS relief program almost certainly trigger an insanely high penalty dating back 7/8 years from the Department of Labor as well?
