Why does a fake ITIN compromise all my Form 5472 filings, not just one year?
I'm trying to understand the scope of exposure if I've used a fabricated ITIN on multiple years of Form 5472. Does only the most recent filing have a problem, or all of them? And does this affect my underlying LLC's status — can the IRS effectively unwind the LLC's existence somehow?
