Watch for these signs that the call is a scam:
Use of fake IRS badge numbers.
Caller knows the last four digits of your social security number.
Caller ID appears as if IRS is calling.
Bogus IRS e-mail is sent as follow-up.
Second call claims to be from police or DMV, again supported by fraudulent caller ID.
Don’t respond in any way to these scams; instead forward the scam e-mail to [email protected], or file a complaint at FTC.gov.
