Late Deposit

I have a controlled group. 

Two of the companies had contributions that were withheld from a participants pay, but didn't make it on the payroll they sent us.  It's very small amounts.  We are giving interest and filing a 5330.   Since it's two different companies, I assume that two 5330's are needed.  Is that correct? 

Correct.  Each employer is responsible for it's own.  I 'think' that if the amount is small enough, you can add it to the earnings allocation in lieu of submitting the form to the IRS.  Haven't done one in a while, but you may verify that.

Good Luck!
