Rules and decisions to review
- Qualification generally looks at your tax home and residence outside the United States and Puerto Rico, or qualifying overseas military duty, on the regular due date.
- Include the required statement explaining why you qualify for the automatic extension.
- Interest generally runs on unpaid tax from the regular payment due date, even when an overseas extension applies.
- An additional filing extension may be requested when appropriate. FBAR deadlines, state returns and other international information filings need separate review.
A practical example
A traveler on a short vacation abroad on the regular filing date should not assume that the overseas extension applies. The relevant residence, tax-home or military conditions must be established.
Records to gather
Gather overseas work and residence evidence, travel dates, prior-year return, estimated payments and foreign income statements.
Your next step
Confirm overseas-extension eligibility and document the reason. Calculate any unpaid tax and interest from the regular due date, then separately calendar information-return and state obligations.
