My stepson received a letter from the IRS saying he owes over $2000 in taxes for income he didn't report. The thing is, he didn't earn the income. He is a college student who has only worked at 2 places in his life (the student union and the airport). They say he has a 1099 from a company in Oklahoma for $8600. He has never been outside the state of Florida. Anyone have any experience with this? The letter syas he must file a petition in the US tax court. What can he provide that proves it wasn't him? Should we try to contact the company that says he worked for them? We already checked his credit reports and there isn't anything funky on there. Thank you!
