I filed my 1040 late but owed no tax — is there a penalty?
The penalty on the return itself is computed by reference to the tax owing and the length of the delay, so a year that settles at nil leaves it little to attach to. The exposure moves sideways. The account and asset reports that travel with the return — the FBAR, which goes to FinCEN and is not attached to the return, and Form 8938 — are charged by reference to the form and the year rather than to the tax. Where the income was reported and only the account report was missed, there is a narrow route to file it late with a reasonable-cause statement, open only while no income is unreported and no examination is under way.
How many years of missed 1040 returns do I have to file?
The duty reaches every year your gross income was above the filing threshold for your status, wherever you were living. What sets the number you actually file is the route back in, and each route defines its own set of years: the streamlined foreign offshore route asks for a limited number of back returns and account reports plus a signed non-willfulness certification, and it turns off the offshore penalties for those who qualify. Choose the route before anything is filed. Some years can be past the refund window while still open to assessment, and the order the years go in decides which reliefs survive.
Can I still claim the foreign earned income exclusion on a late return?
The exclusion is an election made on a return, not a default treatment, so an unfiled year has claimed nothing. Qualification runs through the bona fide residence test or the physical presence test, and the amount is the lesser of your foreign earned income or the annual cap, per qualifying person — US$130,000 for the 2025 tax year and US$132,900 for 2026 — elected on Form 2555 with the return, with a housing amount alongside it. Whether the election is still open on a particular year is checked before anything is drafted, because an assessed year is a different position.
I am self-employed abroad and thought I owed nothing — why is there a balance?
Income tax and social-security tax are separate questions with separate relief. The earned-income exclusion and the foreign tax credit deal with income tax. Neither reaches the self-employment charge; only a totalisation agreement does, and it does so through a certificate of coverage from the system you actually pay into. So a year can settle at nil income tax and still carry a balance. An extension of the time to file is not an extension of the time to pay, so interest runs on that balance from the original due date even where the extension was valid.
I have a green card but live abroad and stopped filing — do I still file?
Yes, on the same footing as a citizen: the duty reaches every lawful permanent resident with income above the filing threshold for their status, wherever they live. A green card is a tax status and not only an immigration one — it keeps you inside the US tax net for as long as it is valid, and abandoning it is a formal act with its own consequences for long-term holders. Moving away is not that act. It matters on the way out, too: Form 8854 asks you to certify compliance with your federal tax obligations for the tax years preceding expatriation, so unfiled years sit in the path of a clean exit.
The IRS has written to me about an unfiled year — what now?
Contact narrows the options rather than ending them, because the cheaper catch-up routes depend on your coming forward first. Establish which notice it is before answering it: each carries a response deadline that changes your rights, and missing it converts a proposed adjustment into an assessed one. The substance of the work then becomes the return itself plus a penalty argument — a documented reasonable-cause narrative with dates and evidence, or the administrative first-time waiver where the filing and payment history supports one. We quantify the exposure year by year, in writing, before recommending a route.
Do I still file a US return if I owe nothing?
Yes. The filing obligation depends on income exceeding the threshold, not on tax being payable, and the reliefs that reduce the bill to nil — the exclusions and the foreign tax credit — are claimed *on* the return, so not filing forfeits them. Information reports about foreign accounts and assets are separate again and carry penalties even where no tax was ever owed. See US citizens abroad.
What is a "dual-status alien spouse", and why is my software asking?
The question comes from the filing-status screens, and it is asking whether your spouse was a non-resident or part-year resident for the year — because if they were, a joint return is not available by default. An election exists to treat a non-resident spouse as a resident for the whole year, which unlocks joint filing at the price of bringing their worldwide income into the US return and their accounts into its reporting. See a US person with a non-resident spouse.
