FATCA Foreign Financial Institution Registration System

Financial Institutions can register using this online FATCA Registration System.

What is it?

The FATCA Registration System is a secure, web-based system that Financial Institutions (FI) can use to register under FATCA. See the FATCA Registration User Guide for instructions on how to register online.

What does it do?

It establishes an online account for FIs to register with the IRS, renew their agreement, and complete and submit FATCA certifications. The FI and their branches are issued Global Intermediary Identification Numbers (GIINs). See the GIIN Composition document for an explanation of this 19-character number.

How do I register?

What happens next?

A registered and compliant Financial Institution that has been issued a global intermediary identification number (GIIN) will appear on a monthly published IRS FFI list. For an overview of the FFI List and how to access it, please see About the FATCA FFI List Search and Download Tool. To learn more about the FFI List and coordination, including withholding and FATCA registration, please see information on FATCA compliance.
