Quick Facts

U.S. withholding agents, foreign financial institutions (FFIs), and other FATCA reporting participants file this form.
It captures the name, address, FATCA ID, and amount of each payment made to a foreign account or entity, plus the type of payment and the FATCA status of the recipient.
The form is due with the annual FATCA filing deadline, generally March 31 of the year following the calendar year of the payments, unless an extension is granted.
Submit Form 8966 electronically through the IRS FIRE system or by paper to the address listed in the form’s instructions for the applicable filing year.
Errors can trigger penalties, additional information requests, or a denial of the FATCA exemption, which may lead to backup withholding on future payments.

Common confusion points

FATCA ID vs. TIN – FATCA ID is the GIIN, not the taxpayer identification number; verify the correct identifier.

Payment type codes – many users select the default code; cross‑check the IRS code list for each transaction.

Electronic vs. paper filing – the same form can be filed both ways; ensure you follow the correct submission instructions.

Reporting threshold – some think any foreign payment must be reported; only payments meeting the FATCA threshold apply.

Recipient status – foreign entities may be exempt; confirm their FATCA classification before reporting.
