FATCA reporting and Form 8938

FATCA (the Foreign Account Tax Compliance Act, enacted in 2010) is a two-sided law: it requires foreign financial institutions to report their American account holders directly to the IRS, and separately requires those same US taxpayers to self-report their specified foreign financial assets on Form 8938. It applies to US citizens, resident aliens, and certain nonresident aliens who hold qualifying foreign assets above the applicable threshold — the institution-reporting side happens automatically in the background regardless of whether you personally file anything, which is exactly the mechanism that makes unreported foreign accounts increasingly hard to keep hidden. See the full FATCA and Form 8938 overview for how the two sides of this law work together.

For Americans living abroad, the threshold is $200,000 in specified foreign financial assets on the last day of the year, or $300,000 at any point during the year, for single filers — doubling to $400,000 and $600,000 for married couples filing jointly. These expat thresholds are four times higher than the thresholds that apply to US residents ($50,000/$75,000 single, $100,000/$150,000 married), reflecting the reality that living abroad naturally means holding more of your financial life in foreign accounts. See the full threshold comparison for how these numbers stack up against the separate, much lower FBAR threshold.

Yes, absolutely — FBAR and Form 8938 are two independent legal tests with different thresholds, different filing agencies, and even somewhat different definitions of what counts as a reportable asset, so clearing or missing one threshold tells you nothing about the other. There's nothing unusual or rare about owing both; it's the normal outcome for anyone whose foreign accounts are large enough to cross FATCA's much higher bar, since FBAR's $10,000 threshold will already have been cleared long before that. See the FBAR vs. Form 8938 comparison for exactly how the two independent tests work.

Form 8938 casts a noticeably wider net than FBAR: beyond foreign bank and brokerage accounts, it also captures directly held foreign stocks and securities that aren't inside any account, interests in foreign partnerships, corporations, and trusts, foreign mutual funds, foreign pensions, and foreign life insurance or annuity contracts with cash value. Directly owned foreign real estate and foreign social security-type government benefits fall outside its scope, as does anything held through a US-based brokerage. See the full list of specified foreign financial assets to check what actually needs to go on your Form 8938.

An initial $10,000 penalty applies for failing to file a complete and correct Form 8938 by the deadline, which can grow by another $10,000 for each 30-day period you remain non-compliant after an IRS notice, up to $50,000 in additional penalties — a maximum exposure of $60,000. If unreported foreign assets also caused you to underpay tax, a separate 40% accuracy-related penalty can apply on top of that to the underpayment itself. See the full Form 8938 penalty breakdown for how these amounts are actually assessed.

There's no exemption simply for holding smaller amounts — you either fall under your applicable threshold or you don't — but certain account and asset types are excluded from Form 8938 entirely regardless of value: accounts at a US branch of a foreign bank, accounts at a foreign branch of a US bank, directly held foreign real estate, foreign currency itself, and foreign government social security-type benefits. An asset already reported on another IRS international form, like Form 3520 or Form 8621, generally doesn't need to be separately listed on Form 8938 too — though its value still counts toward whether you cross the threshold in the first place. See the full list of FATCA exemptions to check whether a specific account or asset is excluded.

CRS (the Common Reporting Standard) is a separate, OECD-developed global framework, adopted by more than 125 countries, under which banks report account holders to their country of tax residence — and notably, the United States itself is not a participating jurisdiction, so FATCA and CRS run in parallel rather than as one unified system. In practice, this means a foreign bank often reports the same American expat's account twice, once to the IRS under FATCA (because they're a US citizen) and once to their country of residence under CRS (because that's where they live) — using largely the same self-certification paperwork for both. See the full FATCA vs. CRS comparison for what this dual reporting means in practice for expats.

FBAR is a Bank Secrecy Act filing made to FinCEN, a Treasury bureau focused on financial crime enforcement, while FATCA's Form 8938 is a tax filing made to the IRS as part of your income tax return — different laws, different agencies, different purposes, even though both exist to surface unreported foreign assets. FBAR uses one flat $10,000 threshold covering financial accounts; Form 8938 uses higher, status-dependent thresholds but covers a noticeably broader range of assets, including things held outside any account at all. See the full FBAR vs. FATCA comparison for the complete picture beyond just the basics.

If you clear the Form 8938 threshold, you've almost certainly also cleared the FBAR threshold, since FBAR's $10,000 bar is dramatically lower than even the smallest Form 8938 threshold ($50,000 for a single US resident) — so in practice, most people who owe a Form 8938 also owe an FBAR, though the reverse isn't true. The safest approach is to check both thresholds independently every year rather than assuming that filing one form automatically means (or doesn't mean) you owe the other, since the underlying asset definitions genuinely differ in places. 

FBAR uses one flat threshold for everyone — $10,000 in aggregate foreign accounts at any point in the year — while Form 8938's threshold depends on both your filing status and where you live: $50,000/$75,000 for single US residents, $100,000/$150,000 married filing jointly, rising to $200,000/$300,000 single and $400,000/$600,000 married filing jointly for anyone living abroad. The gap between the two is enormous for expats specifically — a single filer abroad can hold up to $300,000 in foreign accounts before Form 8938 applies, while the same accounts have been FBAR-reportable since crossing just $10,000. See the full side-by-side threshold table for every filing status combination.

The clearest example is an account where you have signature authority but no ownership or financial interest — a common situation for someone managing a foreign business or family account they don't personally own — which triggers FBAR reporting but isn't reportable on Form 8938 at all. More broadly, any foreign account under Form 8938's much higher threshold but over FBAR's $10,000 bar is also FBAR-only in practice, simply because it never reaches Form 8938's filing requirement in the first place. See the full FBAR vs. Form 8938 comparison for the complete list of coverage differences.

FBAR penalties scale much higher: up to $16,536 per non-willful violation, or the greater of $165,353 or 50% of the account balance if willful, versus Form 8938's flat structure of a $10,000 initial penalty capped at $60,000 total even after continued non-compliance. Both penalty regimes are assessed completely independently of each other and of any income tax penalties you might also owe — a single unreported account can theoretically generate FBAR penalties, Form 8938 penalties, and income tax penalties all at once, none of which offset the others. See the full FBAR penalty breakdown and FATCA penalty breakdown for the full picture on each.

The FBAR is filed electronically and exclusively through FinCEN's BSA E-Filing System (paper filing isn't accepted), completely separate from your tax return, while Form 8938 is attached directly to your Form 1040 and filed with the IRS as part of your regular annual return. This separation trips people up more than you'd expect: filing your tax return on time says nothing about whether you've also filed your FBAR, and vice versa — they're on entirely different systems, with entirely different agencies checking whether you showed up. See the full FBAR vs. Form 8938 comparison for the complete filing mechanics of each.

No — this is one of the most common and costly misconceptions about foreign account reporting: filing Form 8938 does not satisfy, replace, or exempt you from a separate FBAR obligation, and filing an FBAR doesn't exempt you from Form 8938 either. They're independent legal requirements under different laws, and the IRS and FinCEN don't treat compliance with one as evidence of compliance with the other. If both thresholds apply to you, both forms need to be filed, in full, every year.

Beyond being separate filing obligations, FATCA plays a direct role in FBAR enforcement: the automatic account data foreign banks report to the IRS under FATCA gives the IRS an independent way to see which US persons hold foreign accounts, which it can then cross-check against who has and hasn't filed an FBAR with FinCEN. This is a meaningful part of how the IRS identifies non-filers today — a mismatch between FATCA-reported account data and a missing FBAR is a red flag that doesn't require you to have done anything else wrong.
