We have had a significant uptick in IRS rejects due to taxpayer ID showing return already submitted.  Has anyone else seen this anomaly for this filing season? I'm talking about MANY returns, not a few where you could actually say they might be fraudulent activity.  Here is the error: 

Reject: Taxpayer TIN in the Return Header must not be the same as a TIN of a previously accepted electronic return for the return type and tax period indicated in the tax return.

Reject Resolution: This return was rejected by the IRS because the taxpayer's identification number assigned to this return has already been filed and accepted by the IRS. Please verify that you have accurately entered the taxpayer's SSN or TIN and make corrections if required. If no errors have been made in the entry of the taxpayer's SSN or EIN, it may be necessary to contact the IRS at 1-800-829-1040 for further guidance.
