FBAR gets most of the attention in expat tax conversations, but Form 8938 is the one that trips up almost as many people, mostly because it sounds like a duplicate of FBAR and isn’t. If you’ve already read our FBAR guide, keep that mental model in the back of your mind you’re going to need it, because the two forms overlap in confusing ways.

Form 8938, tied to FATCA (the Foreign Account Tax Compliance Act), is filed with your regular tax return, not separately like FBAR. And the thresholds are different sometimes a lot different, depending on your filing status and whether you live inside or outside the US.

The Thresholds Nobody Remembers Correctly

This is where I see the most confusion. People assume the FBAR threshold ($10,000) applies here too. It doesn’t.

For a single expat living abroad, the Form 8938 threshold is $200,000 in specified foreign financial assets at year end, or $300,000 at any point during the year. Married filing jointly abroad doubles both numbers. If you’re living in the US, the thresholds drop sharply $50,000 at year-end or $75,000 at any point for a single filer.

That gap matters. Someone might correctly determine they’re under the Form 8938 threshold while still owing an FBAR filing, because $10,000 is a much lower bar to clear.

Does Crypto Count as a Specified Foreign Financial Asset?

This is the part where even professionals disagree a little, but the general consensus leans toward yes for crypto held through a foreign exchange or foreign financial institution. Self custody wallets sit in murkier territory, similar to the FBAR discussion many advisors don’t treat them as reportable under 8938 because there’s no foreign institution acting as custodian, but this isn’t settled with the same clarity as, say, a foreign bank account.

A Side-by-Side to Keep the Two Forms Straight

	FBAR (FinCEN 114)	Form 8938 (FATCA)
Filed with	FinCEN, separately from your tax return	Attached to your Form 1040
Threshold (single, living abroad)	$10,000 combined, any point in the year	$200,000 year-end / $300,000 any point
Covers self-custody wallets?	Generally no	Generally no, but more debated
Covers foreign exchange holdings?	Generally yes	Generally yes
Penalty for missing it	Can be severe, starts even without willfulness	Can also be severe, plus statute of limitations issues

Notice you can owe one, both, or neither, depending entirely on your numbers. They’re not redundant they’re two separate filters with different mesh sizes.

The Statute of Limitations Trap

Here’s something that surprises people: if you’re required to file Form 8938 and you don’t, the IRS can keep your entire tax return open for audit indefinitely for that year not just the crypto related items, everything. That’s a meaningfully bigger consequence than most people realize when they’re deciding whether this form is “worth the hassle.”

What Counts Toward the Threshold

It’s not just crypto. Foreign bank accounts, foreign stock, foreign mutual funds, and certain foreign pensions all get added into the same total. Someone with a modest crypto position might still cross the threshold once everything else is combined, which is why this isn’t really a crypto specific form it’s a broader expat compliance form that crypto happens to fall into.

What I’d Actually Do

If you’re anywhere near these thresholds, don’t try to eyeball it. Get an actual valuation of your foreign assets as of December 31st and check the running high water mark throughout the year. A lot of expats find out later that a single volatile month say, a crypto rally that briefly pushed their exchange balance above $300,000 before dropping back down was enough to trigger the filing requirement, even though it didn’t feel that way looking at their year end balance.

Where This Fits in Your Overall Picture

Form 8938 doesn’t replace FBAR, and neither of them replaces actually reporting your crypto gains and income on your return. Think of it as three separate questions the IRS is asking: Do you have foreign accounts? (FBAR), Do you have significant foreign assets? (8938), and Did you make money from any of it? (your regular income and capital gains reporting). All three can apply to the exact same crypto holdings, and missing any one of them creates its own separate problem.

If you’ve spent any time digging into expat tax obligations, you’ve probably run into the term FBAR and felt your stomach drop a little. It sounds bureaucratic because it is, and the crypto angle makes it worse, because the rules genuinely haven’t kept up with how people actually hold digital assets in 2026.

Let’s clear up what FBAR is, whether your crypto holdings trigger it, and where the real gray areas still sit because there are a few, and pretending otherwise would be doing you a disservice.

What FBAR Actually Is

FBAR stands for Foreign Bank Account Report, filed as FinCEN Form 114. It’s not technically part of your tax return it goes to the Financial Crimes Enforcement Network, not the IRS directly but the two are closely linked, and missing it can carry steep penalties even if you owed zero additional tax.

The trigger is simple on paper: if the combined value of your foreign financial accounts exceeded $10,000 at any point during the year, you file. Not $10,000 average, not $10,000 at year end if it touched that number even for a single day, the obligation exists.

So Where Does Crypto Fit In?

This is the part that trips people up, because the honest answer is: it depends on where your crypto lives, not what it is.

• Crypto held on a foreign exchange Binance (non US version), Bitget, a local exchange in your country of residence is treated by most tax professionals as a reportable foreign account, because the exchange itself functions like a financial institution holding an asset on your behalf.
• Crypto held in a self custody wallet a hardware wallet, a software wallet where only you control the private keys generally falls outside FBAR’s definition of a “financial account,” because there’s no foreign institution involved. You’re just holding an asset, the same way holding cash under your mattress abroad isn’t itself an FBAR trigger.
• Crypto held on a US-based exchange, even while you live abroad like Coinbase or Kraken isn’t a foreign account at all, so it stays outside FBAR regardless of where you’re sitting when you check the balance.

FinCEN hasn’t issued crystal-clear guidance specifically naming crypto exchanges as reportable accounts the way it has for foreign bank accounts, which is exactly why this remains a genuinely debated area among tax professionals rather than settled law. Some advisors take the cautious route and recommend reporting foreign exchange holdings regardless of the ambiguity; that’s usually the safer call.

A Simple Way to Check Where You Stand

Where your crypto lives	Likely FBAR treatment	Why
Foreign-based exchange (non-US)	Generally reportable if combined foreign accounts exceed $10,000	Treated as a foreign financial account
US-based exchange (Coinbase, Kraken, etc.)	Not an FBAR account	Not a foreign institution, regardless of your location
Self-custody hardware wallet	Generally not FBAR-reportable	No foreign institution holds the asset
Self-custody software wallet	Generally not FBAR-reportable	Same reasoning as above
Foreign crypto lending or yield platform	Often treated as reportable, cautious approach recommended	Functions similarly to a foreign financial account

Why the Ambiguity Doesn’t Mean You Can Skip It

I get why the gray areas feel like an invitation to just not think about it too hard. But the penalties for a willful FBAR violation are severe, and even non willful violations carry real financial consequences. The IRS and FinCEN have also been increasingly focused on crypto compliance broadly, which means the ambiguity is more likely to narrow over time than to stay convenient.

The practical move, if you’re holding meaningful value on a foreign exchange, is to report it. The downside of over reporting is essentially nothing a bit of extra paperwork. The downside of under reporting, if the rules eventually get clarified against you, can be significant.

What This Doesn’t Cover

FBAR is separate from FATCA (Form 8938), which has its own thresholds and its own definition of reportable assets sometimes broader, sometimes narrower depending on your filing status and where you live. It’s also separate from actually reporting your capital gains and income from crypto transactions, which is a distinct obligation regardless of where the assets sit.

In other words: FBAR answers one question do I need to disclose the account? but it says nothing about whether you owe tax on what happened inside that account. Both matter, and they’re evaluated independently.

The Bottom Line

If your foreign exchange balances plus any other foreign accounts crossed $10,000 at any point this year, get a professional opinion rather than guessing. This is exactly the kind of area where a 30minute consultation costs far less than getting it wrong.
