A SCAM!!!!!!  Told me there's an arrest warrant for me from the US Treasury in my name for unpaid taxes.  When I told him that I am current on the taxes, he yelled at me and said no I didn't.  When I told him I receive a refund every year, thanks to my 4 young deductions, he immediately hung up on me.  I assume he wanted me to agree to pay them now and get my info.

Report the Calls to the real IRS here:
•report the incident to the Treasury Inspector General for Tax Administration at 800-366-4484.
•You can also file a complaint with the Federal Trade Commission at FTC.gov. Add "IRS Telephone Scam" to the comments in your complaint.

Do consider maybe getting a call blocking device or phone.. You can google them and many are around $60.00 or so.

Same thing happened here tonight!  My husband contacted a lawyer who sent him to the fraud department.  He was told the IRS will very rarely contact you by phone!  When I googled the number and came up with the above post, I breathed a sigh of relief!  I reported the incident to the IRS number listed above!

I just had similar call from this number by recorded East Indian voice warning of need to call him immediately  regarding pending Federal Criminal Offense, stating not to ignore the message or could be arrested.  I figured immediately that it was a scam. Glad this website proves it is. I will immediately report them to IRS numbers and website given. Thanks!

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. 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://www.ndtv.com/article/india/ex-call-cen ... 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:
