Mandatory Form

IRS REQUIREMENT
Form W-7 (Application for IRS ITIN)

Proof of Business Activity

  • LLC Operating Agreement showing the applicant as a member
  • Partnership Agreement listing the applicant’s name
  • EIN Confirmation Letter (CP 575) for the U.S. entity

Application Process

How Do I Apply for an ITIN?

Complete Form W-7
