DO NOT ANSWER the call UNDER ANY circumstances!!!! IRS ALWAYS
will contact by mail if it is important they will request a signature!!!!!
Actually, they will call you if you omit supporting information, forms, or schedules from an amended return and there is a limited time in which to process your request. In this case you know that you sent them something. If you call them and ask for a manager, who might not be available, and they tell you he or she will call back at a later time. If you are being audited or something like that the auditor might call about an appointment or for documentation or something.
If you don’t think that it is the IRS calling, you can call their 800 number (See the IRS.gov website) and they should be able to see if its the caller is from the IRS, or do a search online as suggested. In this case its already determined that this call was a scam.
Be aware that if the IRS calls they will ask information to confirm your identity, information you should generally never give out. If you are not comfortable with providing that information, even a little bit, don’t give out your personal info. Tell them to put a note in your file with the reason for the call and their business number and you will call the 1-800 number for the IRS and they can confirm the information. You will need to provide things like your social security number and filing status to confirm identity to the IRS phone person when you call, but at least you know you are dealing with the IRS.
