FATCA: Why Being a US Person Makes a Foreign Bank Account Hard

A US citizen living in Europe applies for an ordinary current account and is declined, or is offered a stripped-down version of the product, or is asked to close an account they have held for years. This happens constantly, it is rarely explained well, and it is not a judgement about the customer.

The two facts the whole thing rests on

The United States taxes its citizens on worldwide income regardless of where they live. Almost every other country taxes on residence. That single difference is the origin of the problem, and it means an American who has never filed anything in the US may still have obligations there.

FATCA makes foreign financial institutions report on US accountholders. The regime is implemented through intergovernmental agreements, and in the UK it takes effect through the International Tax Compliance Regulations 2015 — the same instrument that implements the Common Reporting Standard, applying due diligence procedures "set out in the relevant agreement".

Attached to the reporting obligation is a withholding consequence for institutions that do not comply on certain US-source payments. That is what gives the regime its force, and it is why a bank in a country with no other connection to the US takes it extremely seriously.

Why banks decline rather than comply

From a bank's point of view a US customer is a compliance cost with a penalty attached. Identifying them, documenting them, reporting them annually and getting it right every time costs money, and the risk of getting it wrong is disproportionate to the revenue on an ordinary retail account.

Many institutions concluded that the cleanest answer is not to serve US persons at all — or to serve them only in specific product lines where the economics support the overhead. This is usually called de-risking, and it produces the experience Americans abroad describe: not hostility, just a quiet and consistent no.

Investment products are typically harder than payment accounts, because a second layer of securities rules interacts with the first.

"US person" is broader than "American"

The definition catches people who do not think of themselves as American at all.

• Accidental Americans. Born in the US to non-American parents who left in infancy, or born abroad to a US-citizen parent. Citizenship follows the facts, not the memory of them.
• Green card holders, including people who moved away long ago without formally abandoning the status.
• People meeting the substantial presence test through time physically spent in the US, which can catch frequent business travellers.

The practical consequence is that the question on a bank form — are you a US person for tax purposes — is not always answerable off the top of your head, and answering it casually is a mistake in both directions.

The bank's report is not your filing

A recurring and expensive misunderstanding is that once the bank reports, the individual is covered. The two run in parallel and do different jobs. The institution reports what it holds. The person reports what US rules require of them, and US persons with foreign financial accounts have reporting obligations of their own that exist separately from ordinary income tax filing.

The mismatch is the thing to avoid. Where a balance reported by a bank does not correspond to anything the individual filed, both sets of information end up in the same place, and the discrepancy is exactly what the regime was designed to make visible. Consistency is not a nicety here — it is the whole point of the architecture.

What onboarding actually looks like

The question arrives early and it is unambiguous: are you a US citizen, a US resident, or otherwise a US person for tax purposes. Answering yes routes the application down a different path, which at some institutions ends there and at others continues with a request for a US taxpayer identification number and a specific US tax form.

Being asked for that form is a good sign rather than a bad one. It means the institution serves US persons and is doing the documentation properly. Applications that stall for weeks without ever asking are usually applications that will not complete, and chasing them is less productive than starting again somewhere that asked on day one.

What actually helps

• Answer the self-certification accurately, and get advice first if you are unsure. A wrong declaration is worse than a difficult one. Being a US person is not a problem to be hidden; it is a fact to be documented.
• Apply where the answer is already known to be yes. Some institutions serve US persons deliberately and say so. Applying to five banks that do not, and being declined five times, tells you nothing and wastes months.
• Expect the product to be narrower. A payment account is usually achievable. Investment and some savings products are frequently not, at the same institution.
• Keep US filing obligations current, separately. Reporting by your bank and filing by you are different things, and the bank's report existing does not discharge anything you owe.
• Understand renunciation is a serious legal step, not an administrative fix. It is discussed casually online and it is not casual. It is a matter for professional advice.

Why this is not going away

The regime works, from the perspective of the country that built it. The reporting arrives, the withholding threat is credible, and the intergovernmental agreements are in force in a very large number of countries. Nothing about the incentives points toward institutions finding US customers easier to serve.

What has changed, and is genuinely useful, is that the market has segmented. Providers that decided to serve this group properly are now findable, and their onboarding asks the US question early rather than after you have supplied everything else.

The overlap with everything else on this site

FATCA is the older and sharper of two regimes running in parallel. The other, the Common Reporting Standard, applies to almost everyone else with a cross-border account and works on similar machinery — what your foreign bank reports about you covers it in detail, and if you are a US person you are usually in both.

For the practical account-opening side, expat bank accounts and the expat account shortlist are the starting points, and global bank scams to avoid is worth reading before responding to anyone offering a workaround. There is no workaround.

This is general information, not tax or legal advice. US tax obligations are personal, complex and enforced. Take advice from a professional qualified in US tax if any of this applies to you.
