Supposedly a "last call" from the IRS. Total scam.

Treating call stating that  IRS  is suing me. Naturally a scam and should be reported.

They left an ominous sounding message on my answering machine saying the IRS was filing a lawsuit against me.....

There is a widespread IRS (or CRA) or "tax scam" being  practiced by scammers on both USA and Canadian residents.

USA tax payers should read this:

Canadian tax payers should read this:

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