Got exactly same message with Arizona. The IRS never demands immediate payment over the phone and does not take enforcement action directly after a phone conversation. Taxpayers are usually given prior notice of IRS enforcement action regarding tax liens or tax levies. So, take a deep breath and don't panic! Check IRS official website.https://www.irs.com/articles/irs-warning-about-phone-scams. In the end, call the TIGTA at 1-800-366-4484
to report the incident.
