The IRS does not call you---EVER--- and they do not email you. If you are getting calls or emails that claim to be from the IRS they are scams. Do not give any information to anyone who calls you or emails you and says they are from the IRS. The IRS will only contact you by mailing a letter to the address you used on your tax return.
