A foreign bank account is completely legal. Not reporting it is where people get into real trouble.
This site explains why millions of people - expats, international workers, dual citizens, business owners - legitimately hold foreign bank accounts, and the FBAR and FATCA reporting obligations that go with them for US persons. We do not sell offshore structures or banking access, and nothing here replaces a licensed cross-border tax professional.
What are you actually trying to figure out?
What actually goes wrong with foreign bank accounts
These aren't hypothetical warnings - they're the specific, documented ways an honest, well-intentioned foreign account turns into a real problem.
- FBAR and FATCA non-disclosure penalties can be significant even where there was no intent to evade tax and no tax was actually owed on the account - the obligation is triggered by account value, not by intent or by a tax liability.
- Foreign banks can close accounts held by US persons on relatively short notice, as a compliance-cost decision rather than anything specific to the individual account holder.
- Relying on an unlicensed 'asset protection' or 'offshore' consultant instead of a licensed cross-border professional - legitimate guidance comes from someone accountable to a real, checkable license, not a sales relationship.
- Assuming outdated banking-secrecy assumptions still apply - the large majority of foreign financial institutions now report US account holder information to US authorities under FATCA, making non-disclosure a much worse bet than it may once have been.

These tools help you compare fees, structure your thinking, and check your readiness — they do not calculate tax owed or file anything.
Conversion cost check
See what a quoted exchange rate and margin actually cost you when moving money between countries — useful once you're transferring funds as part of a relocation or foreign account setup.
Assumptions this uses
- You supply the quoted rate; this tool never fetches or estimates a live market rate
- The margin/spread percentage is entered by you, based on what your provider discloses or what you calculate against a published mid-market rate
- This does not include flat transfer fees some providers charge in addition to the spread
- This is not a tax calculation — it only measures the cost of the currency conversion itself
Limitations: This does not account for flat fees, receiving-bank charges, timing risk if the rate moves before settlement, or any tax consequences of the transfer itself.

The one-sentence test that keeps you on the legal side
Having a foreign bank account is legal. Reporting it, when required, is what keeps it that way. If anyone frames a foreign account as a way to keep money invisible from a tax authority, that is not banking advice - it is a description of the exact thing that turns a legal account into a legal problem. When in doubt, that question is worth taking to a professional.

Foreign bank account questions, answered plainly
The questions people actually type. Where the honest answer is "it depends," we say what it depends on.
Is it legal for a US citizen to have a foreign bank account?
Yes. Holding a foreign bank account is completely legal for US citizens, green card holders, and residents. What creates legal exposure isn't the account itself - it's failing to report it when reporting is required, which is a separate legal obligation from paying tax on the account.
What is FBAR?
FBAR stands for Report of Foreign Bank and Financial Accounts. It's an annual disclosure certain US persons must file with the US Treasury if the combined value of their foreign financial accounts exceeds a set threshold at any point during the year. It's filed separately from a tax return, and it's required regardless of whether the accounts generated any taxable income.
What is FATCA and how is it different from FBAR?
FATCA (Foreign Account Tax Compliance Act) requires foreign financial institutions to report US-owned account information directly to US authorities, and separately requires certain US taxpayers to disclose foreign assets on their tax return. FBAR is a Treasury filing about accounts; FATCA involves both bank-side reporting and a taxpayer-side asset disclosure. Many people with reportable accounts have obligations under both.
Why do so many foreign banks refuse to open accounts for US citizens?
It's usually not personal - FATCA imposes real compliance costs and reporting duties on foreign banks that accept US clients, and many smaller banks decide the administrative burden isn't worth it for the accounts involved. This is a well-documented, practical problem, not a sign anything is wrong with your situation.
What's the difference between a foreign bank account and an offshore trust or corporation?
A foreign bank account is a simple deposit relationship with a financial institution abroad. A foreign trust or corporation is a distinct legal entity with its own formation, governance, and reporting requirements - generally far more complex, with its own specialized disclosure forms. Moving from an account to a structure like this is a significant step up in complexity that needs its own dedicated professional guidance.
If I don't owe any tax on my foreign account, do I still have to report it?
Generally yes. FBAR and FATCA reporting thresholds are typically based on account value, not on whether the account produced taxable income. Treating reporting as optional because no tax is owed is one of the most common ways people end up with unintended legal exposure.
