A man with very broken english said he was with the IRS and I owed $6000 plus in back taxes.  He asked for my name and address.  I told him if he knew I owed back taxes, he should have my that information.  Obviously a scam.  Told him to go get F'd.  He hung up.

Same thing just happened to me!

Left an automated message saying the IRS was filing a lawsuit against me and I must call back.  Of course it's a scam.  One, the IRS will pay you a visit and/ or you will talk to  a real person.   Furthermore I own nothing to the IRS I've never held anything to the IRS. Very annoying at 7 AM in the morning!

Left message saying the IRS was filing a law suit against me. I called back, and a man with a thick foreign accent began asking for my name and address. After I tried spelling it multiple times and he didn't understand, I hung up. Looks like it was a scam anyway, so it's a good thing I didn't give any more information.

By calling them back you just verified for them that yours is a "good' number and now you will receive more worthless calls. Do not answer call you don't know and never call them back.
