<prompt> Human: IRS sent me a letter stating Id under-reported my income in 2016. Surprise, a company Ive never worked for filed a 1099-MISC on me, and that company filed for bankruptcy early this year.Ive contacted the IRS and got the companys current mailing address and sent a letter via registered mail stating how the 1099-MISC is erroneous and asking them to file a corrected 1099-MISC for 0 of compensation. Once I get the registered-mail receipt back, Ill then CC the IRS as a formal response to their underpayment letter. Anybody know what happens when the bankrupt company takes no action to rectify this?Is there any other method to prove the negative that I didnt get compensation from them? The added tax burden amounts to 1600, so, Im loath to hire a lawyer to actually fight this since I figure Id be just as well off to pay the IRS and wash my hands of it.  <response>: It occurs to me that someone who worked for them may have stolen your identity.
