For U.S. citizens and green card holders living overseas, Form 8938 has a paradox at its heart. On one hand, you almost certainly have foreign accounts — that's just life abroad. On the other, the thresholds that trigger the form are dramatically higher for you than for someone back home. Understanding both halves is the key to getting it right.
The obligation follows the passport
The U.S. taxes its citizens and residents on worldwide income no matter where they live. Form 8938 works the same way: moving abroad doesn't end your filing obligations, it just changes the numbers. If you're a U.S. citizen or resident and you file a U.S. tax return, the Form 8938 question is on the table regardless of which country you now call home.
The higher thresholds
This is the good news for expats. If you qualify as living abroad, your thresholds jump substantially:
| Filing status (living abroad) | Year-end value over… | …or any-time value over |
|---|---|---|
| Single / head of household | $200,000 | $300,000 |
| Married filing jointly | $400,000 | $600,000 |
| Married filing separately | $200,000 | $300,000 |
Compare that to the $50,000 / $75,000 single threshold for someone living in the U.S., and you can see why an expat with a modest local savings account often falls under Form 8938 even while clearly over the FBAR's flat $10,000 line.
"Living abroad" is a defined test — not just where you sleep
To use the higher thresholds, your tax home must be in a foreign country, and you must meet either the bona fide residence test or the physical presence test (generally 330 full days in a foreign country during a 12-month period). A U.S. resident who merely travels a lot doesn't qualify. If you don't meet the test, you use the lower domestic thresholds even if much of your money is overseas.
The FBAR gap that catches expats
Here's the trap that snares Americans abroad more than anyone: the FBAR's $10,000 threshold does not get the expat bump. It stays flat regardless of where you live. So a U.S. citizen in Spain with $120,000 in local accounts is comfortably under the $200,000 Form 8938 threshold but far over the FBAR line — they must file the FBAR and may not need Form 8938 at all. It's the mirror image of the domestic situation, and assuming the two move together is a reliable way to get one of them wrong. See Form 8938 vs. FBAR.
Everyday accounts count
When you live abroad, your "foreign" accounts are just your normal accounts — your salary lands in one, your rent leaves from another. It's easy to mentally exclude them because they don't feel exotic. But for Form 8938, a checking account in your country of residence is a specified foreign financial asset like any other. Add in a local pension from your job (usually reportable — see Foreign Pensions and Form 8938) and expats often cross thresholds they didn't realize applied.
The deadline works in your favor
One bit of relief: because Form 8938 travels with your tax return, the automatic filing extensions available to Americans abroad apply to it too. Taxpayers whose tax home is overseas generally get an automatic extension to June 15 to file their return, with a further extension available to October. See Deadlines & Penalties.
Multiple years, multiple currencies, real complexity
Expat situations tend to stack complications — several countries, a foreign pension, currency swings, and sometimes years of unfiled forms discovered all at once. This is exactly where general guidance runs out and a professional who handles expat returns earns their fee. Use this article to understand the shape of the problem, not to resolve a multi-year one on your own.
