This is a Pakistan or India based IRS scam. Do not fall for this.

The IRS does not initiate any legal action over the phone. Report it also to your local law enforcement agency. The scammers use voice over IP lines (e.g. magicjack (Ymax corporation). This is always against these companys' terms of use and can lead to termination of their contract. However only law enforcement can initiate the contact if you yourself are not a customer. Ultimately this is a case for the FBI legal attache in Islamabad. If you are really annoyed: call or write to your representative in Congress. As these scams happen all over the country maybe this will trigger a reaction (and the NSA can finally be a force for good).
We keep getting calls from this number. It says Washington DC on the ID and the guy has a strong Middle Eastern accent. He is supposed to be calling about an approval for a $5,000 loan which we have not applied for.......ever!! He calls a couple times a day. I am now going to block his number. I suspect the call is being "spoofed" from somewhere over seas.
Got a call from this number. Said he was from Federal Tax Dept/ Said I was being sued. Do I have an attorney? I said "Federal Tax Department? Are you saying you are a part of the Federal Government? IRS? He said yes. I said "I would have known if I was getting sued. You would have sent me something". Gave me a number of 888 392 8424, said to verify with a Luke Marshall. Got disconnected with that number, or rather never went through. Called back original number to see if anyone answered. Same guy, heavy accent, ,maybe Indian, said IRS. Who uses term Federal Tax Department? Glad I found this site.
