I received an email with that same phone number to our business email address stating that they were the IRS and that our tax return was under investigation and to view the report and then give them a call. However, we had not even filed our taxes for 2013 yet. I did not open it for fear it might be harmful. Will phone the IRS about this problem.
I received an email with an attachment and similar content about my return. This says that the IRS made an error after processing which requires my immediate attention. I am sure this is a scam. I will delete the email.
