IRS Form 8809-I – IRS Forms, Instructions, Pubs 2026 – If your organization must file Form 8966 (FATCA Report) but needs extra time, IRS Form 8809-I provides the official way to request an extension. This guide covers everything about IRS Form 8809-I — from who needs it and key deadlines to step-by-step filing instructions, based on the latest IRS guidance as of 2026.
Form 8809-I remains the current form (November 2015 revision) with no updates required. It allows filers of Form 8966 to request more time to meet FATCA reporting obligations under Chapter 4 of the Internal Revenue Code.
What Is IRS Form 8809-I?
IRS Form 8809-I, titled Application for Extension of Time to File FATCA Form 8966, requests an initial automatic 90-day extension or an additional 90-day hardship extension to file Form 8966.
- Form 8966 reports information on U.S. accounts held by foreign financial institutions (FFIs), substantial U.S. owners of passive non-financial foreign entities (NFFEs), and other FATCA-required details.
- Form 8809-I applies only to Form 8966 extensions — it is separate from the general Form 8809 used for other information returns like 1099s.
