Depends on the law you break. If you are cheating them out of money they would be on your tail in no time. In this case they are making money.
Why should they care where it is coming from?
So, it's okay to break some laws, just not others? They are supposed to apply the LAW to everyone. I realize what they have working for the IRS. I've met many of them. I wouldn't want to work with any of them. Some of them are damn clueless.
It took me about three weeks to prove I paid something that I had a receipt for. I spent more on copying, faxing and mailing the proof than I was supposed to have owed. I didn't want it on my record that I owed them anything so I proved I didn't owe it, FINALLY!
