The IRS does not call you! If they need to contact you, they will write. These people are into extortion scam, and claiming to be IRS is one of the many federal or state id's they will fake. They have also used DEA and Police amongst many to sound like "your going to jail" unless you pay x  amount of $$$.

Got a call from 916-844 2381 from an  East Indian sounding "Mark Wright" .When I redialed I spoke to one American sounding  " Nathan Rice" who said I could contact him at this number 916 243 5342 Said we owed thousands to the IRS..We needed to pay it within the hour, other wise they as attorneys for the IRS would begin the legal process

916 844 2381 is part of this scam...They are in Walnut Creek today 9/11

This is a criminal extortion scam operating out of India. They are making the calls utilizing VOIP and the names of legitimate firms to make it appear the calls are originating from within the US. There is NO "company" or "debt" and you will NOT be arrested. They are harvesting and/or buying consumers' personal identifying information from unscrupulous websites like the one you may have filled out an application with, and you need to do whatever you can to protect yourself. This includes: Notifying the FTC: https://www.ftccomplaintassistant.gov/, placing fraud alerts with all three credit bureaus, notifying your bank and employer and letting these criminals know you are aware they are attempting to extort money for a non-existent debt and have alerted the authorities.

ABC News released an investigative report on this scam a year ago:
