You may think you're a hot shot for pulling a fast one on the IRS. But when the friend you entrusted with your secret snitches on you in exchange for a fat check, you're going to be in big trouble.

"Most cases start the old-fashioned way," said Ian Comisky, a partner at law firm Blank Rome LLP who represents taxpayers whose returns were flagged by the IRS. "You blab about it to a friend, colleague, spouse or girlfriend, and one of them turns you in."

Even your closest pals may be tempted to tattle, since the IRS offers whistleblowers a reward of up to 30% of any additional tax or penalties it collects from tax cheaters.

And with the popularity of social media, it's now much easier to publish private information publicly. So if you did something you think was questionable, don't post it all over Facebook.
