Called and said they were calling from the IRS and done an audit and that there is a problem with my tax return... My understanding is the IRS does not call taxpayers directly before sending correspondence through the mail.
I had a woman with a thick accent saying her name was Karen Smith, that she was from the IRS and calling for my mom (why!) saying that she had evaded taxes for past several years (2008-2014) and owed $2000. My parents are both teachers and have NEVER had an issues with the IRS. Please! Beware of these people. Scammers.
