As I said before, you need to find out more.  In some cases, the W-2 may be correct when it doesn't show any Social Security or Medicare wages.  Just because the prior preparer filed 8919 does not necessarily mean that is correct.

Find out exactly what type of work this person does for the W-2 and who is paying him.  And is he a student?  Nonresident Alien?  Minister?  Household Employee?  Some other special circumstance?
