What is FATCA (Foreign Account Tax Compliance Act)?

A US federal law requiring foreign financial institutions to report accounts held by US persons to the IRS, and requiring US taxpayers to report foreign financial assets exceeding certain thresholds.

FATCA is arguably the most consequential piece of US financial surveillance legislation for Americans abroad. Enacted in 2010 (effective 2014), it effectively turned every foreign bank in the world into an unpaid IRS informant.

How FATCA Works

FATCA has two arms:

1. Foreign Bank Reporting (the big one)

Foreign Financial Institutions (FFIs) in over 100 countries are required to:

  • Identify account holders who are US persons
  • Report their account balances, interest, dividends, and other income to the IRS annually
  • Withhold 30% on certain US-source payments to non-compliant institutions

2. US Taxpayer Reporting (Form 8938)

US persons must file Form 8938 (Statement of Specified Foreign Financial Assets) if their foreign financial assets exceed:

Filing Status Living in US Living Abroad
Single $50,000 (year-end) / $75,000 (any time) $200,000 (year-end) / $300,000 (any time)
Married Filing Jointly $100,000 / $150,000 $400,000 / $600,000

Why FATCA Matters for Privacy

  • Banks refuse Americans: Thousands of foreign banks simply refuse to open accounts for US persons rather than deal with FATCA compliance costs
  • Automatic reporting: Your foreign bank sends your balance and income data directly to the IRS — no subpoena needed
  • Global reach: Over 100 countries have signed Intergovernmental Agreements (IGAs) with the US to enforce FATCA
  • Chilling effect: Americans abroad face increasing difficulty accessing basic financial services

The Real-World Impact

  • Many foreign banks, brokerages, and insurance companies have closed accounts of US persons
  • Americans abroad struggle to get mortgages, investment accounts, and even basic checking accounts
  • FATCA compliance costs foreign banks an estimated $8 billion annually
  • Some Americans have renounced citizenship specifically because of FATCA's impact on their ability to bank abroad

CRS: FATCA Goes Global

The Common Reporting Standard (CRS), developed by the OECD, is essentially FATCA for the rest of the world. Over 100 countries now automatically exchange financial account information with each other. The US notably has not joined CRS (it doesn't need to — it has FATCA), which makes the US itself one of the largest tax havens for non-US persons.

Penalties for Non-Compliance

  • $10,000 penalty for failure to file Form 8938
  • Additional $10,000 for each 30-day period of non-filing after IRS notice (up to $60,000)
  • 40% penalty on underpayment of tax attributable to undisclosed foreign financial assets
  • Criminal penalties possible for willful violations
