This is ludicrous.  A W-2 is a legal document to which the IRS already has access  When it is issued by an employer, it is essentially a representation on the part of the employer on the accuracy and completeness of the numbers involved.  Making follow up calls to verify what was put on the W-2 should only be done if the IRS has reason to believe the original W-2 issued was fraudulent.

At a time when the agency is severely strapped for resources, why are they wasting their time on this type of crap?
