In general, you should be very skeptical of anyone who calls you on the phone, pretending to be from the IRS. The IRS will always send you a notice first. Also, don't believe anyone who threatens to have you arrested if you don't pay.
If you get a phone call from someone who says they're from the IRS, don't give them any personal information, or any bank account or credit/debit card information, or any information at all. Do not pay them through any means, including wire transfer. Just hang up and call one of these numbers:
- If you think you might owe back taxes, call the IRS at 1-800-829-1040.
- If you're sure you don't owe any taxes, report the incident to the Treasury Inspector General for Tax Administration, at 1-800-366-4484, or online at www.tigta.gov .
