It has been brought to our attention that members may be receiving phone calls from an automated call system stating that they are with the IRS. The automated message suggests that you are part of a lawsuit and would you like to speak to a representative. To our knowledge, this is a scam phone call and should be treated with serious consideration. It is highly recommended that you DO NOT PROVIDE any personal information until you have verified that you are speaking with an actual IRS official.
