Here’s what you should do if you think you’re the target of an IRS impersonation scam:

If you actually do owe taxes, call the IRS at 1-800-829-1040. IRS workers can help you with a payment issue.

If you know you don’t owe taxes or do not immediately believe that you do, you can report the incident to the Treasury Inspector General for Tax at 1-800-366-4484.

If you’ve been targeted by any scam, be sure to contact the Federal Trade Commission and use their “FTC Complaint Assistant” at FTC.gov. Please add “IRS Telephone Scam” to the comments of your complaint.
