For US citizens holding cryptocurrency on foreign exchanges, the rules around reporting aren't just confusing-they can cost you thousands in penalties if you get them wrong. The IRS isn't asking you to guess whether your Bitcoin or Ethereum counts as a foreign asset. FATCA already says it does, and the consequences of ignoring it are real.
What FATCA Actually Covers
FATCA, or the Foreign Account Tax Compliance Act, was passed in 2010 to stop Americans from hiding money offshore. It forces foreign banks and financial institutions to report accounts held by US persons to the IRS. If you have a bank account in Canada, a brokerage in Switzerland, or a crypto wallet on a platform based in Singapore, FATCA likely applies. The key here is "specified foreign financial assets." That phrase includes:- Financial accounts at foreign institutions
- Stocks or securities issued by non-US companies
- Financial instruments with non-US issuers or counterparties
When Do You Have to Report?
FATCA reporting kicks in based on how much you hold and where you live. There’s no gray area: if you cross the threshold, you file Form 8938 with your tax return.- Single filers living in the US: Report if you held over $50,000 on the last day of the year OR more than $75,000 at any point during the year.
- Married filing jointly, living in the US: Report if you held over $100,000 on the last day OR more than $150,000 at any time during the year.
- Single or married filing separately, living abroad: Thresholds jump to $200,000 on the last day or $300,000 at any time.
Cryptocurrency Is Treated Like Any Other Asset
The IRS hasn’t issued a 10-page memo saying "crypto counts under FATCA." But it doesn’t need to. The definition of "specified foreign financial asset" is broad enough to include it. Foreign exchanges like Binance, Bybit, or KuCoin are considered financial institutions under FATCA. If they have US customers, they must report those accounts to the IRS. And here’s the catch: if the exchange reports your holdings, the IRS already knows you have them. Not reporting on your end isn’t hiding-it’s lying. The IRS cross-checks data from foreign institutions with what you file. Missing crypto? That’s a red flag. Many people assume, "I didn’t get a 1099, so I don’t have to report." That’s wrong. FATCA reporting doesn’t require a form from the exchange. It requires you to disclose the asset. Even if the platform doesn’t send you anything, you still have to list it.
How to Report Crypto on Form 8938
Form 8938 doesn’t have a "crypto" box. That’s why people get confused. You report it under "other financial instruments" or "other foreign financial assets." You list:- Name of the foreign institution (e.g., Binance Limited, registered in the Cayman Islands)
- Address (if unknown, write "unknown" or use the platform’s registered headquarters)
- Account number (if provided-many crypto platforms don’t issue them)
- Maximum value during the year (in USD)
- Value on the last day of the year
FBAR Is Also a Risk-And It’s Getting Worse
FATCA isn’t the only rule. There’s also FBAR (FinCEN Form 114), which requires reporting foreign financial accounts over $10,000 at any time during the year. Historically, crypto wasn’t included. But in 2024, FinCEN proposed new rules to explicitly include cryptocurrency accounts. That means by 2026, if you held $11,000 in Ethereum on Kraken (a foreign platform), you’d need to file TWO forms:- Form 8938 (FATCA)
- FinCEN Form 114 (FBAR)
What Happens If You Don’t Report?
The IRS doesn’t send letters saying "you missed crypto." They find it through:- Data shared by foreign exchanges under FATCA agreements
- Whistleblower tips
- Matching transaction history from US-based exchanges (like Coinbase) with foreign holdings
- Audits triggered by unreported income
How to Stay Compliant
Here’s what smart people do:- Track every foreign crypto holding. Even if it’s small now, it might grow. Use a spreadsheet or crypto tax tool like Koinly or CoinTracker.
- Report conservatively. If you’re unsure whether a platform counts as foreign, assume it does.
- Use the highest value. Don’t wait until year-end. Track peak value during the year.
- File Form 8938 even if you’re below threshold. It’s easier to file and get it over with than risk an audit.
- Don’t rely on exchanges. They won’t tell you to report. They’re not your tax advisor.
What’s Coming Next
Regulators aren’t slowing down. By 2027, expect:- Explicit IRS guidance on crypto valuation methods
- Standardized reporting fields for crypto on Form 8938
- More countries sharing crypto data with the US under FATCA
- FBAR becoming mandatory for all foreign crypto accounts
Do I need to report crypto on FATCA if I only hold it and never sell?
Yes. FATCA requires reporting of foreign financial assets based on value, not activity. Holding $60,000 in Bitcoin on a foreign exchange for the whole year still triggers Form 8938, even if you never traded it.
What if my crypto is stored in a hardware wallet outside the US?
If the wallet is self-hosted and not held by a foreign financial institution, it likely doesn’t count under FATCA. But if you use a foreign custodial service (like a crypto trust or foreign exchange that holds your keys), it does. The key is custody, not location.
Can I file Form 8938 after the tax deadline?
You can file an amended return with Form 8938, but you’ll still owe penalties for late filing. The IRS may waive penalties if you prove reasonable cause, like not knowing about the requirement. But ignorance isn’t automatic protection.
Do I need to report crypto held on a US-based exchange with foreign parent company?
If the exchange is registered and regulated in the US (like Coinbase US), you don’t report it under FATCA. But if the platform is legally based overseas-even if you access it from the US-it counts. Check the company’s legal registration, not where you log in.
What if I inherited crypto from a relative overseas?
Inherited crypto held on a foreign platform counts as a specified foreign financial asset. You must report it on Form 8938 if it meets the value threshold. The source doesn’t matter-only the location of custody.
