No. In fact, it’s quite unlikely that you will ever hear anything about it as long as the amounts are low. For instance, the IRS has had the resources to audit about 1 in 220 taxpayers who submitted a return in recent years. However, for every 219 who file without incident, there’s one unlucky soul who has the unpleasant experience of receiving an audit. You can cut your chances of being that person way down if you just go ahead and pay taxes on your winnings.
