Abstract
A 2025 Belgian Data Protection Authority (DPA) decision and ensuing preliminary questions referred by the Belgian Market Court to the Court of Justice of the European Union (CJEU) highlights the tension between the General Data Protection Regulation (GDPR) and the US Foreign Account Tax Compliance Act (FATCA) structure in Europe. The FATCA structure relies on intergovernmental agreements (FATCA IGAs) between the US and EU Member States. Under these agreements, Member State tax authorities transfer personal data of their citizens and residents to the US Internal Revenue Service (IRS). It may be determined that these transfers violate some or all of the GDPR’s personal data protections. If that occurs, the incentive for Member States to re-negotiate FATCA IGAs include protecting their financial institutions from 30% withholding on US-source income. However, given the gaps between the US legal protections of data processed by the IRS and what is required by the GDPR, the US Congress would need to enact substantive legislation to provide protections substantially equivalent to what is provided by the GDPR. This article analyses three potential bases on which FATCA IGAs could comply with the GDPR and describes the significant legislative intervention each would require of the US Congress.
