"Client found that their payroll system was not accurately calculating match for employees participating in Catch-Up. The correction should be to make up the missed match along with any earnings, correct? And there is no waiver or anything (Similar to missed deferrals caught early enough to avoid the need for a QNEC) that exists for match, is there?
"That said, if they do not correct this during the year, these employees
should be made whole when the company funds their year-end match true-up. I have never seen these include earnings.
"Is there any reason for this and is there anything the client should consider before choosing one option versus the other? If "correcting" this with the true-up and not funding earnings an issue? Is there a reason that this should be done with earnings because it violates any rule?
"The client
is the one who brought this up as they don't see why it should matter how they do it as long as they do and I want to make sure I explain what they're missing, if anything."
