Just got a call from this number stating they are the IRS and filing a lawsuit against me. Called back and they wanted confirmation of my home address to continue - sounded like a scam to me!

Yep.  You are right.  Block the calls if you can, or don't answer.   This is the new popular scam.  The IRS does not call you.  Stay Safe!

I just got the same recorded call saying the IRS is filing a lawsuit against me. I googled the number and found this forum. I will not call the number. Thanks for the warning.

Just called this number back and I think it is definitely a scam! When I told them I could only make monthly installments of $20.00 he hung up on me!! So scary!

I just got the same call, same message.  At the exact same time I got a call from 202-304-5707 with the same automated voice saying the same thing that the IRS was filing suit.  So you'll probably be getting another call soon from this other number also.
