The Worldwide Tax Scope of the United States
The United States is one of only two nations globally that taxes its citizens and lawful permanent residents (green card holders) on their worldwide income, regardless of where they reside or where that income is earned.
Alongside income taxation, the federal government enforces aggressive informational reporting requirements under the Bank Secrecy Act (BSA) and the Foreign Account Tax Compliance Act (FATCA). Failure to file informational returns carrying zero tax liability can trigger statutory civil penalties exceeding $10,000 to $100,000 per violation.
1. FinCEN Form 114 (FBAR): The $10,000 Aggregate Rule
Under 31 U.S.C. § 5314, every "United States person" (citizens, residents, domestic corporations, partnerships, and trusts) who has a financial interest in, or signature authority over, foreign financial accounts must file an annual Report of Foreign Bank and Financial Accounts (FBAR) if:
The aggregate maximum value of all foreign financial accounts exceeds $10,000 at any point during the calendar year.
Crucially, the $10,000 threshold is an aggregate sum across all accounts, not per account. If a taxpayer holds four foreign accounts with $3,000 each, the aggregate is $12,000, and all four accounts must be formally disclosed on FinCEN Form 114.
2. FATCA Form 8938 vs. FBAR: Key Distinctions
Many taxpayers confuse FBAR with FATCA Form 8938 (Statement of Specified Foreign Financial Assets). Both must frequently be filed concurrently:
- FinCEN 114 (FBAR): Filed electronically with the Financial Crimes Enforcement Network (FinCEN) by April 15 (with an automatic extension to October 15). Governed by Title 31 (Bank Secrecy Act).
- IRS Form 8938 (FATCA): Filed directly with federal income tax return Form 1040 by the tax return due date. Governed by Title 26 (Internal Revenue Code). Higher thresholds apply ($50,000 for single domestic filers; up to $400,000 for married expat filers).
- Asset Scope: Form 8938 includes foreign stocks, securities, partnership interests, and foreign grantor trust interests that are not held in a financial account.
3. Severe Penalties for Non-Compliance
The statutory penalties for failure to file an FBAR are among the most severe in the federal code:
- Non-Willful Violations: Up to $10,000 per violation (adjusted annually for inflation, currently over $15,600) under 31 U.S.C. § 5321(a)(5)(B).
- Willful Violations: The greater of $100,000 or 50% of the maximum account balance for each year of non-compliance, plus potential criminal referral.
4. Rectifying Delinquent Filings: Streamlined Procedures
Taxpayers who failed to disclose offshore accounts due to non-willful conduct can utilize the IRS Streamlined Filing Compliance Procedures:
This formal amnesty protocol requires filing the previous 3 years of amended tax returns and 6 years of delinquent FBAR reports, accompanied by a non-willful narrative certification. Eligible expatriates pay zero penalties; eligible domestic residents pay a reduced miscellaneous 5% offshore penalty, fully shielding themselves from criminal prosecution and draconian willful assessments.
