Having a Swiss bank account is completely legal for a U.S. person — but it comes with U.S. reporting. The account itself usually isn't taxed; the income it generates is reportable, and the account may need to be disclosed.
Two kinds of obligation
- Reporting the account: the FBAR (combined accounts over $10,000) and possibly Form 8938 (FATCA).
- Reporting the income: interest, dividends and gains the account produces are reportable on your return.
What Swiss banks report
Under FATCA, Swiss banks report U.S. account holders. Keeping your filings consistent with that reporting is the safest approach.
