💡 If you hold foreign stocks, you likely need to file both Form 8938 and an FBAR — missing either one can cost you far more than the taxes themselves.
Why Foreign Investment Filing Trips Up Even Savvy Investors
Here’s something most people don’t realize until it’s too late: owning foreign stocks isn’t just a tax question — it’s a reporting question. Two completely separate obligations. And the IRS doesn’t care which one you were confused about when it hands out the penalties.
I’ve spent time going through the IRS guidance and cross-referencing it with FinCEN requirements, and honestly, the overlap between these rules is where most mistakes happen. You could owe zero dollars in tax and still face a $10,000 fine just for failing to file the right form.
So let’s break this down clearly, because foreign investment filing is genuinely one of the most misunderstood areas of U.S. tax law.
💡 Form 8938 goes to the IRS; FBAR goes to FinCEN — they’re different agencies, different thresholds, and different deadlines.
Form 8938 vs. FBAR: The Two-Headed Reporting Beast
Most investors who hold foreign stocks encounter two distinct requirements. Understanding the difference matters enormously.
Form 8938 (FATCA) is filed with your federal tax return. It’s required when your foreign financial assets exceed certain thresholds — and those thresholds vary depending on your filing status and whether you live in the U.S. or abroad.
FBAR (FinCEN Form 114) is filed separately, directly with the Financial Crimes Enforcement Network. The threshold here is simpler: if the aggregate value of your foreign financial accounts exceeded $10,000 at any point during the year, you file. Period.
Notice that the FBAR threshold is much lower. A friend of mine — a 40-something who’d been investing in European ETFs through a foreign brokerage for years — had no idea the FBAR even existed. His accountant caught it during a review. The account value had crossed $10,000 briefly one quarter. Technically, he’d been non-compliant for three years.
The fix was a streamlined disclosure procedure, not a disaster. But it required amended returns, explanatory letters, and a meaningful chunk of professional fees. All because of a form he’d never heard of.
When Exactly Do You Need to File?
This is where it gets nuanced. The FBAR threshold applies to accounts — brokerage accounts, bank accounts, even certain pension accounts held at foreign institutions. Form 8938 applies more broadly to assets, which includes foreign stocks held even through a domestic account if they’re reported as foreign financial assets.
Here’s the thing: if you hold shares of a foreign company through a U.S. broker like Fidelity or Schwab, you generally don’t have a foreign account for FBAR purposes. But you may still have reportable foreign financial assets for Form 8938 purposes. The rules genuinely do diverge.
A few triggers to watch:
- Direct ownership of stocks on a foreign exchange through a foreign brokerage account
- Interests in foreign mutual funds or ETFs domiciled outside the U.S.
- Foreign partnerships, trusts, or pension arrangements
- Stock in a foreign corporation held directly (not through a U.S. custodian)

💡 Failing to file FBAR can trigger penalties up to $10,000 per violation for non-willful violations — and up to the greater of $100,000 or 50% of account value for willful ones.
The Consequences Nobody Talks About Honestly
Let me be direct here: the penalty structure for non-compliance is genuinely scary. And the IRS has been increasing enforcement of foreign asset reporting steadily.
Non-willful FBAR violations can result in penalties of up to $10,000 per violation, per year. Willful violations — meaning you knew about the requirement and ignored it — can escalate to criminal prosecution in extreme cases. The IRS Offshore Voluntary Disclosure Program closed in 2018, but streamlined procedures still exist for those who qualify (roughly: non-willful failures and no current audit).
Am I the only one who finds it strange that you can owe $0 in additional tax but still face a five-figure penalty? That asymmetry is real, and it’s why compliance matters even when your foreign holdings are small.
Practical Record-Keeping That Actually Works
The best defense against compliance problems is systematic records. Here’s what I’d recommend tracking throughout the year — not just at tax time:
- Monthly account statements from every foreign financial institution — screenshot or PDF, not just login credentials
- Cost basis documentation including the original purchase price in both the foreign currency and USD at time of purchase
- Exchange rates used — the IRS accepts the Treasury’s published rates or a consistent published source; document which one you use
- Dividend and interest records separately from capital gains, since they’re taxed differently
- Year-end and highest-balance figures for every account, since both matter for different forms
One investor I know keeps a simple spreadsheet that auto-pulls end-of-month balances for each foreign account. Takes about 20 minutes to set up once, then she updates it quarterly. At year-end, her CPA has everything needed in one place. That kind of system pays for itself the first time you actually need it.
The bottom line with foreign investment filing? The rules are complex, but they’re not unknowable. A one-time investment in understanding the requirements — and setting up clean record-keeping — beats the alternative by a wide margin.
