They just called from this number and are stating that the IRS is filing a lawsuit against you and you need to call them back at the number.  Do not call.  I repeat do not call!!!  If the IRS is suing you or needs to get a hold of you they will mail you something and they do not give out their "direct line."  They have a 800 number you call back not a direct line.

A call from 'Freeport, TX' from the "IRS" about a lawsuit, blah, blah. Obvious scam. Blocked.

If it was the IRS, the number would either come from Washington, D.C. area or Austin, Texas.

The IRS has a processing center where mailed-in returns are handled, and they have a walk-in office (appointment times have to be made) in a strip mall at the Rundberg intersection with Interstate 35. They might have another office elsewhere in Austin, but I have not looked for it. In 2010 the IRS had an office on Research Boulevard (US Highway 183) and Joe Stack flew his airplane into that building. https://en.wikipedia.org/wiki/2010_Austin_suicide_attack

The IRS does not initiate communications
with a threatening "cold call" to unsuspecting people.
Instead
The IRS always sends snailmail letters first!

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