Right there is your answer. My best friend is in the tax collecting business and they shut down shady ass people every day. Think about it , they are stealing revenue from the state which in turn causes the state to lose money and in turn the state has to raise your taxes to make up for it. Do you wish to pay more taxes so he can have free money? Do yourself and everybody in your state a favor and turn him in.A call to the local tax collector or state revenue office should do the trick.
