Yeah, this one is darned if you do and danged if you don't.  If they didn't activate the 8812 we'd have people here complaining "why didn't the software remind me to enter the ACTC my client received for his every-other-year dependents?"

It seems fairly easy to make it go away and I'd rather my clients get the "you have to repay this" surprise from me than the love letter from the IRS months from now.
