Yes, the IRS confirms this is a scam. Just go to their website and search on IRS Phone scams. The IRS never initiates contact with a taxpayer by phone, always by US Mail. Any phone calls or emails claiming to be from the IRS are scams unless you had already called the IRS and are working with them on a problem.
Caller said shes calling from IRS said they want me to call them asap and if they don't hear from me they would issue a warrant for my arrest with local police department. I called IRS they said they would never call anyone.
