"This is officially a final notice that the IRS is filing a lawsuit against you." Though I'm surprised no one has reported this number yet, this must be a scam. I'm in good standing with regard to taxes, and the IRS uses the US Postal Service ANYway.

called me twice am sure it is scam as well

called me twice today

Yahoo search says number is a new one started on 5/31/2016    i guess that is why so few complaints       they also phonrd me i just never answer numbers unknown to me   thx
