Oh, good grief, I did that one (BARE) a few years ago. What a circus that was! BARE provided me with a W-2 for the business NEXT DOOR to the tax preparer! I handed him my W-2 and he reads it and says "I've never seen you in there." Gulp! So I say, I work in accounting, I stay in the back office. OK. That seems reasonable. "Why is your employer ID different from everyone else's?" He goes to a file cabinet, pulls out half a dozen returns, brings them to the desk, and compares employer ID numbers off the W-2. He does the taxes for all my fellow employees!!!
Egad. I just said, well, I work for Corporate. I don't know if that makes any difference. He looks at me and says, oh, yeah, probably different departments have different ID numbers.
I wonder if he ever went into that other business looking for me....
