FATCA & Form 8938 for Americans in Switzerland

How FATCA affects U.S. persons with Swiss accounts, how Form 8938 differs from the FBAR, and what Swiss banks report.

FATCA is the U.S. law behind much of the reporting Americans abroad encounter. It has two sides: Swiss banks report U.S. account holders to the authorities, and U.S. persons may have to file Form 8938 with their tax return.

Why your Swiss bank asks if you're American

Under FATCA, Swiss financial institutions identify and report U.S. account holders. That's why you may have been asked to confirm your U.S. status or complete a form. It also means consistency between what your bank reports and what you file matters.

Many U.S. persons in Switzerland file both the FBAR and Form 8938. They overlap but are not the same.

Frequently asked questions

Does FATCA mean I owe more tax?
Not by itself — FATCA is mainly about reporting. Whether you owe U.S. tax depends on your income, credits and exclusions. But the reporting is required regardless.
My Swiss bank sent me a FATCA form — what should I do?
Confirming your U.S. status is routine. The more important step is making sure your U.S. filings (return, Form 8938, FBAR) are consistent. Start with the Tax Risk Check.
What are the Form 8938 thresholds?
They're higher than the FBAR and depend on your filing status and whether you live abroad. Because they vary, it's worth confirming for your situation rather than assuming.
