I'm in the minority by not having a membership in the "one good lie deserves another" club.  Just because the employer made a mistake, why claim the taxpayer is running a business?  Next thing you know the Census Bureau will be sending questionnaires about how many employees and products, and the state revenue people might be asking about sales tax.  

I would attach an explanation to the return and tell the client that if a CP-2000 is received, use it for the reply.  I'd give a 90% guarantee that will work.  Life is always uncertain.
