1) not always. Ive gotten a $300 from citi before.
2) you need to double check and make sure the company did not issue one out. Your best bet would be to call and ask. if they dont know, and u see no tax forms on your account, then u "can" not report it. If they do in fact have a form out, then the IRS will penalize you saying that you "should" of known. its a really bad situation to be in, safe side, report it. take the risk, save some money.
Note: i am not a CPA and everything i have said is based on what ive seen from my own tax returns and others. For a better response, its best you ask a CPA.
