FBAR (FinCEN 114) & FATCA (Form 8938) Guide for US Digital Nomads: $10k Threshold & Penalties
Everything American remote workers must know about reporting foreign bank accounts, non-US digital wallets, fintech balances, filing deadlines, and penalty relief.
Under the Bank Secrecy Act (BSA), United States citizens, green card holders, and resident aliens who maintain foreign bank accounts, overseas brokerage accounts, or foreign digital wallets must disclose these accounts to the Financial Crimes Enforcement Network (FinCEN). Failing to file an FBAR (FinCEN Form 114) carries severe statutory penalties, even if you owe zero US income taxes.
1. The $10,000 Aggregate Threshold Explained
The most critical rule regarding FBAR is the aggregate balance test. You are required to file if the combined maximum balance of all your non-US financial accounts exceeds $10,000 USD at ANY point during the calendar year.
Scenario Example:
- Account 1 (Spain Santander): Maximum peak balance = $4,000.
- Account 2 (Wise multi-currency non-US balance): Maximum peak balance = $3,500.
- Account 3 (Thailand Bangkok Bank): Maximum peak balance = $3,000.
Total Aggregate Peak: $4,000 + $3,500 + $3,000 = $10,500.
Because the aggregate exceeds $10,000, you must report all 3 accounts on your FBAR, even though no single account exceeded $10,000 on its own.
2. Do Digital Wallets (Wise, Revolut) Count as Foreign Accounts?
The IRS and FinCEN treat financial accounts based on where the financial institution holding the funds is organized:
- Wise (formerly TransferWise): If your Wise account is registered through Wise Inc. (US entity) with US routing and account numbers, it is a domestic account. However, if your account is holding foreign currency balances routed through foreign banking partners (e.g., Wise Europe SA or Wise Payments Ltd in the UK), FinCEN advises reporting these balances if aggregate thresholds are met.
- Revolut: If registered with Revolut Ltd (UK) or Revolut Bank UAB (Lithuania), it is classified as a foreign financial institution and is fully reportable.
- Local Foreign Bank Accounts: Any account opened with a local bank abroad (e.g., BBVA, N26 Germany, Kasikornbank) is 100% reportable.
