To authorize the IRS to discuss your return with someone else (for example, a relative or paid tax preparer), you must provide that person's name, phone number, and PIN (any 5-digit number created by the designee). This information will be entered into the Q&A and will print on Schedule 6 (Form 1040), Foreign Address and Third Party Designee.
Tax professionals should complete the Paid Preparers section of Form 1040, Page 1 and check the 3rd party Designee checkbox.
