This is a Pakistan or India based IRS scam. Do not fall for it. The IRS does not initiate any legal action via phone.

As general background information, here are a few things you can do:
1) Report it to TIGTA under http://www.treasury.gov/tigta/contact_report_scam.shtml especially if you have become a victim (lost money, gave personal information etc.). You can also file a complaint with the Federal Trade Commission at ftc.gov/complaint (include “IRS Telephone Scam" in your complaint). This way you can also help the government establish specific fraud patterns.
2) Help kill their phone lines but not by calling them back directly (the number may be spoofed and repeat calls by you may - under exceptional circumstances - amount to harassment). The scammers use Voice over IP lines (e.g. magicJack (Ymax corporation)) to make it seem as if they are calling from the US. This is always against these companys' terms of service and can lead to immediate termination of their contract and blocking of their IP addresses for future attempts to register. Do a reverse look up of their telephone number (e.g. www.whitepages.com) to identify the Voice over IP provider and report it to the company and/or law enforcement (local police and/or state attorney general)
3) 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 provide US law enforcement agencies with the political backing and the resources they need to work in India and Pakistan together with local authorities (it can happen, read: http://m.ndtv.com/article/india/ex-call-centr ... mmission-320427). A US task force has already been set up in Jamaica to nab scammers there (see http://www.ice.gov/doclib/news/library/reports/cornerstone/cornerstone7-1.pdf). You can use the following template for your letter (more powerful!) or email:
I did write my Congressman - explained how some of these calls are akin to domestic terrorism - like the IRS scam or the fake miscrosoft virus scam - botht of which can scare the crap put of you when you first get them. I explained in my letter how the DNC list was not working and that more needed to be done to enforce it and regs needed to be in place to force phone carriers to provide call blocking services (Verizon says my landline service can't be used to block call right nows - only if I upgrade to FIOS, can I dio that - f'them).
Congressman's reply - the DNC is a wonderful tool. Pelase register with it and make any complaints to the FCC, etc.
Sigh...it's like talking to a wall. Still if more people did it - this topic may get the atention it deserves.
My mom got very threatening calls from this number. Is there any way to report the number so no one else has to go through this? Seems impossible to actually talk to an irs representative in person to report it.
