FATCA: Foreign Account Tax Compliance Act

FATCA was enacted by the United States Congress and is enforced by the Internal Revenue Service (IRS). The law places two parallel obligations on the table: foreign financial institutions (FFIs) must report information about accounts held by US persons to the IRS, and individual US taxpayers must disclose foreign financial assets above specified thresholds using IRS Form 8938. Unlike the FBAR (Foreign Bank and Financial Account Report), which is a wholly US domestic reporting mechanism, FATCA operates through intergovernmental agreements. The IRS has entered into agreements with over 110 foreign countries, with hundreds of thousands of foreign financial institutions reporting US account holder information directly to the IRS.\n\nThe practical result is that banks, brokerages, and other financial institutions outside the United States are required to conduct due diligence on their customers to identify US persons and report qualifying accounts. Institutions that fail to comply face withholding penalties on certain US-source payments. In 2026, compliance is treated by regulators and institutions as a core governance matter, not merely a technical filing exercise.

For US citizens and Green Card holders living in the GCC, FATCA has direct consequences. When you open or maintain a bank account, investment account, or brokerage account in the UAE, Saudi Arabia, Qatar, Bahrain, Kuwait, or Oman, the institution is obligated to identify whether you are a US person and to report your account details to the IRS if applicable thresholds are met. This means US expats in the Gulf should expect to receive FATCA letters or certification requests from their local banks - this is standard procedure, not a cause for alarm.\n\nFATCA reporting by your Gulf bank does not replace your own individual filing obligation. If you hold foreign financial assets above the IRS threshold, you are required to file Form 8938 with your annual US tax return. Form 8938 and the FBAR are separate requirements and cover overlapping but distinct asset categories. Consult a qualified cross-border tax adviser to confirm which forms apply to your specific situation. This article is not tax advice.
