I hate to say this because I myself do not like snitches' but in this case I think the IRS should be informed...Agree with Nammac... my wife did taxes for 15yrs. When she did them for free in conjunction with AARP (blech, commie bastards), illegals would come in with using an extended family member's SS# or TIN and use it to claim the EIC. It was sickening, but the AARP instructed their volunteer tax preparers not to make an issue or report it, saying that the FEDS don't care as long as there is a number on the form. Sigh.
Thank you for your service...
