FBAR Reporting for Crypto Holdings Abroad

Crypto Betting September 19, 2025

Introduction
As cryptocurrency becomes a global asset class, U.S. taxpayers with crypto holdings in foreign wallets or exchanges must be aware of FBAR reporting requirements.

The Financial Crimes Enforcement Network (FinCEN) mandates that U.S. citizens and residents report foreign financial accounts exceeding certain thresholds, and this now extends to digital assets held abroad. Understanding FBAR rules for crypto holdings is essential to remain compliant and avoid substantial penalties.


1. What Counts as a Foreign Account
FBAR rules apply to foreign financial accounts in which a U.S. taxpayer has a financial interest or signature authority.

This includes accounts on exchanges headquartered outside the U.S., self-custody wallets held in another country—especially multi-signature wallets hosted internationally—and other foreign financial accounts such as custodial accounts, brokerage accounts, or trusts holding digital assets.

Any account exceeding an aggregate balance of $10,000 at any point during the calendar year must be reported, and this threshold applies collectively across all foreign accounts.


2. Filing Requirements and Process
U.S. taxpayers must file the FBAR using FinCEN Form 114, which is separate from the federal income tax return. The form requires detailed information, including the financial institution’s name, account number, maximum value during the year, and the type of account.

Taxpayers must report crypto holdings in USD at the highest value during the year. Failing to file or providing inaccurate information can result in significant civil and criminal penalties.


3. Common Challenges for Crypto Holders
Reporting crypto holdings abroad presents unique challenges. Determining the fair market value of crypto in foreign accounts can be difficult due to exchange rate fluctuations. Investors often use multiple foreign exchanges or wallets, which increases the complexity of reporting.

Cross-border transfers between foreign accounts or exchanges may also create confusion regarding which accounts need to be reported. Proper documentation and consistent tracking of all foreign crypto accounts is critical to overcoming these challenges.


4. Best Practices to Stay Compliant
To ensure FBAR compliance, investors should maintain detailed records of all foreign wallets and exchanges, including account balances, transaction histories, and dates of ownership. Using crypto accounting software can simplify the aggregation and conversion of foreign account values to USD.

Consulting a crypto-focused CPA experienced with FBAR and cross-border reporting ensures that filings are accurate, complete, and submitted on time, reducing the risk of penalties or audits.


Conclusion
U.S. taxpayers with foreign crypto holdings must understand FBAR reporting requirements to remain compliant and avoid penalties. Accurate valuation, consistent record-keeping, and timely filing are essential components of proper reporting.
