I'm pretty sure this is going to be hard to fight, but there was a paper extension filed and the IRS says they never received it.  Now they are saying, even though he got his social in time had the extension been processed, they are withholding EIC because they have no extension on file.  Is there anything that can be done in this situation? I am not the preparer but I feel bad since it is close to $6000 they are losing and I am pretty sure they are out of luck .
