Robo call supposedly from I.R.S., but out of Bellingham, WA. ? Probably a scam. If the I.R.S. wants to get hold of you they write and call personally.

Left numerous messages from 360-347-1794 & 360-851-4838, stating a lawsuit was filed against me by the IRS. When calling back the numbers on Saturday morning, the phone just rings and rings. This has to be a scam.. The IRS I'm sure has an automated system at the least.

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.

Recent news story:

Bogus call. Received a voice mail with the recorded message regarding a "Lawsuit from IRS". Returned the call but of course there was no answer. The U. S Department of the Treasury does not call threatening lawsuits. The first and any contact from the US Department of the Treasury, many people refer to as the IRS, will be by a letter.

Didn't fool me,looked the number up,was a scam,already reported.
