Do I need Form 2350 if I moved abroad partway through the year?
Often, yes. The test that lets you claim the exclusion is met over a period rather than on a single date, so somebody who left in the autumn will still be working towards qualification when the ordinary deadline arrives. Filing at that point means filing without the exclusion. This extension exists for exactly that gap: it asks for time so the return can go in once the bona fide residence or physical presence test has actually been satisfied. The request has to say which of the two tests you are relying on and when you expect to meet it, so the first thing we do is settle the dates before anything is sent.
Is Form 2350 different from the ordinary extension for individuals?
Yes, and the difference is why people miss it. The ordinary extension is open to any individual filer who wants more time, for any reason at all. This one is granted for a single purpose: so that a filer abroad can finish becoming eligible for the foreign earned income or housing exclusion. That purpose has to be stated, which means naming the test and the date you expect to meet it. If your reason for needing time is a late foreign slip or an unfinished set of accounts rather than qualification, the ordinary extension is the form that fits.
Whose test does the extension rest on if we file jointly?
Each spouse qualifies on their own facts. One may have been abroad for a full year while the other arrived months later, and the exclusion is claimed per qualifying person, so a joint return that relies on both needs both to have met a test. In practice we work out each spouse's expected qualification date separately and date the request from the later of the two, because a request that runs out before the second spouse qualifies leaves the problem it was meant to solve. We keep a presence record for each of them rather than one household record.
Most of my income is investments. Is this the right extension for me?
Probably not. The exclusion reaches earned income only, meaning wages and self-employment income for services performed abroad, and it is capped per qualifying person at $130,000 for the 2025 tax year. Dividends, interest, capital gains, pensions and rents sit outside it entirely. If your income is mostly of that kind, waiting to qualify buys nothing, because the thing you are waiting for will not shelter it. The relief that does apply is the foreign tax credit for tax the other country has already taken. We have told filers to drop a planned request for this reason.
Do I still need it if the exclusion will wipe out my US tax?
The two questions are unconnected. The extension is about time to file, and it is needed precisely because the thing that will wipe out the tax is not yet established. Until the test is met the exclusion cannot be claimed, so a return filed early is a return showing the income without the relief. There is a trap in the other direction too: extra time to file is not extra time to pay. Where a balance will arise anyway, from self-employment abroad or from investment income the exclusion never touches, interest runs on the unpaid amount from the original due date, so the estimate that accompanies the request matters.
Can I use it for a later year, not just my first year abroad?
Yes. Nothing about it is confined to the year you left. The question is the same every year: will the test you are relying on be satisfied by the ordinary deadline, or only after it. A qualifying period that straddles a year end, a break in the middle of an assignment, a spell of home leave that interrupts a run of days abroad, any of these can push the date you become eligible past the deadline for a year that is not your first. We see it most often in a second year, where the filer assumes the first year's answer still holds.
What is expat tax?
Not a separate tax — it is the ordinary tax of one or more countries applied to someone living outside the one that claims them. In practice it means two systems at once: the filing your home country still requires, the filing the country you live in requires, and the relief provisions that stop the same income being taxed twice at full rates. What makes it specialist work is that the relief has to be claimed in the right country, in the right order. See our expat filing work.
When is Form 1116 not required?
Three situations. You elect the exception for a small amount of creditable foreign tax that arises from passive income and is reported to you on a payer statement such as a 1099 or K-1. You choose to deduct the foreign tax instead of crediting it. Or all the foreign income was excluded under the foreign earned income exclusion, in which case there is no credit to claim on it in the first place. The first option costs you the carryover. See Form 1116.
