The IRS impersonation scam is one of the most persistent cons out there. It reappears every few months, and this summer it's back with a vengeance. BBB has received numerous complaints about aggressive calls by fake IRS agents. How the Scam Works:You get a call from someone claiming to be from the IRS. In the most recent version of this scam, the "IRS agent" informs you that you are being sued for unpaid taxes. She/he may give you a fake badge number and name. The "representative" tries to pressure you into paying a fee by using a prepaid debit card or wire transfer. If you don't pay up immediately, the "IRS agent" will sign a warrant for your arrest. No matter how much the caller threatens you, don't fall for it! How to Spot an IRS Impostor Scam: Here are some ways to spot a fake IRS agent. Be wary if you are being asked to act immediately.
