There is a fairly common IRS or "tax scam" being practiced by scammers on both Canadian and USA residents.
USA tax payers should read this:

Short answer:
The IRS never initiates a contact via phone.
They always send a snailmail first.

IRS law suit call: I did not return the call from 06-866-5733. I remember hearing the IRS always sends written notice. I googled and read this site's http://www.irs.gov/uac/Newsroom/IRS-Reiterate ... Telephone-Scam- information regarding scam calls like this. Thanks for the help and posting!
I received a threatening call from 938-568-3601 telling me to call back number 06 905 1078 to avoid a lawsuit being filed by IRS. Of course, I did not call back this number nor do I intend to as the IRS will never contact you via telephone. Just wanted to share to help others. The originating call number is different than what other have reported here, but, the call back number is the same. Hope this helps someone. Voice was digital and female.
