I'm Calling From the IRS

The phone rings, and there is a man on the other end who says you owe the IRS money.  If you don't pay with a credit card over the phone right then, they say the police will arrest you.

The IRS will never demand payment over the phone, and never makes phone calls.  If you do owe the IRS money, they will only contact you through the mail.  Never give your credit card information to someone who calls you.  If you think it may be a legitimate call from a utility or other company, tell them you will call them back.  Look up their phone number in the phone book or online, and call them to make a payment.
