The IRS is once again warning people to beware of phone calls from people who claim to represent the Internal Revenue Service and demand money.
The IRS typically contacts people by mail, not phone, about unpaid taxes. The IRS won’t ask for payment using a prepaid debit card, wire transfer or request credit card information over the phone.
If you receive a call from someone claiming to be with the IRS and demanding payment, investigators recommend hanging up and calling the IRS or reporting the incident online.
