Filing and deadlines for Americans abroad
Living abroad can change when a return is due, but it does not create one simple expat filing rule. Start by checking whether a federal return is required, then identify the forms and dates connected to your income, accounts and filing history. Filing, payment, extensions and FBAR dates use separate rules. This guide connects the relevant checks and keeps the official source beside each answer.
