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.
"My Swiss account is small" doesn't settle it — the FBAR threshold is the combined peak across all your accounts.

What Swiss banks report

Under FATCA, Swiss banks report U.S. account holders. Keeping your filings consistent with that reporting is the safest approach.

Authorities cited

  • 31 CFR §1010.35031 CFR §1010.350 — FBAR (FinCEN Form 114) filing requirement and $10,000 threshold
  • FinCEN Form 114 (FBAR)Report of Foreign Bank and Financial Accounts (FBAR)
  • IRS Form 8938About Form 8938 — Statement of Specified Foreign Financial Assets
  • IRC §6038DIRC §6038D — Information reporting of specified foreign financial assets (Form 8938)

Frequently asked questions

Is it illegal for a U.S. citizen to have a Swiss bank account?
No — it's legal. What's required is reporting it (where thresholds are met) and reporting the income it generates.
My bank froze my account or asked about U.S. status — why?
Banks manage FATCA compliance and sometimes restrict or review U.S.-person accounts. From the U.S. side, the key is keeping your reporting current and consistent.
Do I report the balance or the income?
Both can apply: the account may be reportable (FBAR/8938 by value), and the income it earns is reportable on your return.
