Form 8809-I: Application for Extension of Time to File FATCA Form 8966
Form 8809-I is the application a filer uses to ask for more time to file Form 8966, the FATCA Report. The instructions say it is used to request an initial or additional extension of time to file Form 8966 for the current tax year.
The filers are FATCA reporting entities, such as financial institutions, Direct Reporting NFFEs, and Sponsoring Entities or trustees reporting for the entities they sponsor. The instructions say a separate request is submitted for each filer, and a separate Form 8809-I is filed for each method of filing Form 8966, electronic or paper.
The instructions describe an automatic extension of 90 days from the original due date, and an additional 90-day extension under a hardship exception that is not automatically granted. You can fill out the form free in your browser on this page and download it without an account.
