The Expat’s Guide to IRS Extensions: When and How to File Form 4868

Need more time to file your U.S. tax return while living abroad? You’re not alone. Many expats find themselves needing additional time to gather documents or finalize foreign income details. Fortunately, the IRS makes it easy to file for an extension.
🗓️ Automatic Expat Extension to June 15
All U.S. citizens living abroad on April 15 automatically get a 2-month extension to June 15 to file their federal return. However, any taxes owed were still due April 15 to avoid interest charges.
📝 Need More Time? Use Form 4868
Still not ready by June 15? You can file Form 4868 to request an extension until October 15.
- It’s easy to file electronically or by mail.
- The extension only applies to filing, not payment.
- Interest will continue to accrue on any unpaid tax.
⚠️ What You Still Need to Do
- Estimate your tax liability when submitting Form 4868.
- Pay any owed taxes by April 15 to reduce or avoid penalties.
- Still file FBAR (FinCEN 114) by October 15, if applicable.
Filing an extension gives you breathing room—but don’t ignore it. Working with a professional ensures deadlines are met, documents are accurate, and penalties are avoided.
