Reports of a new phone in scam have started to surface related to an IRS warrant.
The call is typically a computer generated message outlining that there is a pending unpayable IRS Warrant issued for your arrest and you need to return a call to a specified number (425-616-2822 has been most common) for legal advice. All of these statements are false. The IRS does not communicate in this fashion.
