Definition

The US regime requiring reporting of foreign financial assets by taxpayers and of US accounts by foreign institutions, backed by withholding.

Why the term matters

Information-reporting terms describe obligations that arise on facts rather than on tax owing, and whose penalties are charged per form and per year. That asymmetry — large exposure against nil tax — is the single most common reason a cross-border file becomes expensive.

The team reviewing a file together at a desk

Where the two countries disagree

The recurring problem with a term like this is that two systems use the same word for different things. Where that happens, the question is never "what does it mean" but "whose definition governs the question in front of me" — and the answer decides the filing.

Where you will actually see it

Putting it to work

A term like this is worth ten minutes of reading and then a conversation. The reading tells you the question; the conversation answers it. The quote comes before the work, in writing.

The point of reading an entry like this is to recognise the question when it appears in your own paperwork. Answering it needs your facts, your years and your documents, and none of those is on this page.

Cross-border situations we are engaged for

Case study 1

Answering a bank’s certification letter and reconciling what it reported

A client received a certification request from a bank abroad more than a decade after opening the account, with a reply date set by the bank. We established her status from her own documents, answered the request, and then asked the bank what it had reported in earlier years and on what basis. The two accounts of the same account did not match: the bank held one address and one balance date, her own records another. The engagement produced a signed certification, a reconciliation of the bank’s figures with hers, and a note on file explaining each difference.

Case study 2

Owner-level certification for a private company account abroad

A company held its operating accounts in one country and its shareholder lived under US reporting obligations. The bank asked the company to identify its owners, which the directors read as an enquiry into the company’s tax. It was not. The institution needed to know whose accounts these were for its own reporting. We worked from the share register and the constitutional documents to establish who had to be named, and what the shareholder separately had to report himself. The engagement produced the company’s certification and a written division between what the company reports and what the individual does.

Case study 3

Recovering amounts withheld while a certification was outstanding

Payments into a client’s account abroad had been reduced for two years because a certification the institution needed had never been returned. The client had assumed the deductions were a local tax. We identified what the institution required, supplied it, and then dealt with the amounts already withheld as a separate matter, with the institution and on the client’s returns for the affected years. The engagement produced the certification, a corrected treatment going forward, and a documented claim for the withholding already suffered.

Case study 4

Years of institution reporting with no taxpayer filing behind them

A client’s bank had reported his accounts diligently since the regime began. He had filed returns throughout and had never filed the taxpayer-side statement of his foreign holdings, on the understanding that the bank was doing it for him. We set the bank’s reporting side by side with his returns to show what each had said, established which years were open, and prepared the missing statements from an inventory of his holdings rather than from the bank’s figures. The engagement produced a filed set of years and a schedule showing how every holding had been classified.

Case study 5

When an institution would rather close an account than certify it

A client was told his accounts abroad would be closed rather than certified, by a bank that had decided his category of customer was not worth the compliance. Arguing was not available to him. The work was to make sure the closure did not damage his own filings: establishing the balances and the dates, obtaining statements before the relationship ended, and recording what the bank had reported while it existed. The engagement produced a complete record of the closed accounts and a sound basis for the years that still had to be filed.

Case study 6

A plan administered abroad and the question of who certifies it

An employee joined a savings arrangement run by her employer’s administrator outside the United States and was handed a form she did not recognise. The administrator wanted her status; she wanted to know what she would have to report. Those are separate questions with separate answers, and the plan documents were needed for both. We read the arrangement, established what the administrator was certifying and what her own interest consisted of, and set the two out side by side. The engagement produced the completed certification and a written note of the reporting position for later years.

Case study 7

A Relief That Turned on Days Nobody Had Recorded

Treaty exemption, residence and social security are each decided by a count that has to be evidenced rather than recalled. The engagement builds the record from tickets, rosters and payroll before applying any article.

An Indian Company Paying a Foreign Supplier

Payments abroad carry deduction at source and a certification filed before the money moves. Whether the treaty reduces the rate depends on what is being bought, and the classification is the decision the whole filing rests on.

Core International & Cross-Border Tax Services

International Tax Planning & Advisory

Strategy and compliance for income, assets and families spread across borders.

One coordinating team: filings on every side of the border are sequenced so treaty relief and foreign tax credits are claimed once — and in the right country.

U.S. & Cross-Border Tax Returns

Dual filers: U.S. citizens in Canada and Canadians with U.S. income run two parallel systems — we prepare both, in the right order, every year.

Expat & Emigration Tax

The move year is its own project: the elections and valuations filed that year decide the next decade of both countries’ returns.

Non-Resident Canadian Tax

Default withholding is 25% of gross: elective returns routinely turn over-withheld rent and pensions into refunds.

Transfer Pricing & BEPS

Documentation prepared with the return is the cheapest insurance in international tax; reconstructing it during an audit is the most expensive.

Cross-Border Estates & Trusts

Wills drafted for one country routinely misfire in the other — deemed disposition here, estate tax there, credits in between.

Cross-Border Corporate Tax

Expansion raises the same four questions every time — entity, PE, repatriation, payroll. We answer them before the tax authorities do.

India Tax for NRIs & Returning Residents

The deduction is taken on the sale price, not the gain — which is why an NRI property sale strands cash unless the certificate is applied for before closing.

Canadian Tax with a Foreign Element

Residency is decided on facts, not on a form — and the year you arrive or leave is the one where the largest amounts turn on the smallest details.

UAE Tax for Expats & Their Home Country

A zero-tax country is only half the answer — the question that decides the bill is whether the country you came from still treats you as resident.

Software revenue crosses borders by default — sourcing rules, withholding on licence-like payments and IP location decide the effective rate.

Software revenue is rarely taxed where the team sits. Licence, subscription and service income are characterised differently by each side, and the answer decides withholding at source, treaty relief and whether a foreign customer creates a taxable presence at all — questions that are cheap to settle before the contract and expensive afterwards.

What people ask us about FATCA

Why is my bank asking whether I am a US person?

Because the bank, not you, is the one being asked. FATCA has two halves: taxpayers report their foreign financial assets, and foreign financial institutions report the accounts they hold for US persons. The second half is backed by withholding, so an institution that cannot establish who its account holders are carries a cost of its own. That is why the letter arrives from a bank you may have used for decades, why it carries a deadline set by the bank rather than by a tax authority, and why it does not go away if you ignore it. Answer it accurately, and keep a copy of what you told them.

Does my bank reporting under FATCA mean I need not file?

No. The two halves of the regime are separate obligations owed by different people, and one does not discharge the other. Your bank’s report says that an account exists and what it held. Your own filing says what you hold and, on the return itself, what it earned. It is common to find that a bank has reported faithfully for years while the taxpayer-side statement was never filed at all — and the bank’s diligence is exactly what makes that visible. Treat a certification you have signed for a bank as a sign that the information is already moving, not as a filing you have made.

What happens if I ignore my bank’s FATCA certification request?

The institution acts to protect itself. It is the one carrying the exposure and it cannot wait indefinitely for a customer to reply, so it will apply whatever default treatment its own rules provide for an account it cannot certify — which can mean withholding on payments into the account, reporting it on an unresolved basis, or restricting what you can do with it. None of those outcomes is a tax decision about you, and none can be appealed to a tax authority, because no tax authority made them. The practical response is to establish your status, answer the request with documents, and deal separately with anything the bank has already done.

How does withholding enforce FATCA if nobody withholds from me?

The pressure is applied upstream. The regime does not rely on individuals volunteering information; it makes the flow of certain payments to a non-participating institution expensive, so the institution has a commercial reason to collect and report the information itself. You feel that indirectly — as a certification request, as questions when you open an account, as a form to sign when a plan is administered abroad. Understanding it explains something clients find baffling: the bank’s insistence is not officiousness and it is not negotiable at branch level. It is the mechanism, and the branch is the last place it can usefully be argued.

Does my country’s agreement with the United States change what I file?

It usually changes how the information reaches the United States rather than what you owe as a taxpayer. Many countries collect the account information from their own institutions and pass it on, which is why your bank may report to its local authority instead of directly. For you that changes the paperwork the bank asks for and the timetable it works to. It does not touch the taxpayer half of the regime. So the questions on your own file stay the same: which of my holdings fall in the reportable class, which filings do they belong on, and can I show how each figure was arrived at.

I am a US citizen abroad who has never heard of FATCA — what now?

Start with an inventory, not a form. List every account, plan, policy and shareholding you hold outside the United States, with the institution, the currency and the years you have held it. Almost every difficult question in this area is a classification question, and classification is impossible until the list exists. Then two things can be worked out: which items fall within the reportable class, and which of your years are still open. Only after that is it worth deciding what to file and in what order. Clients who begin by filling in a form usually have to start again, because the form asks questions the list answers.

What is a PFIC, and why do Canadian mutual funds cause trouble for US persons?

A passive foreign investment company is a non-US company that is mostly passive by income or by assets — which describes almost every Canadian mutual fund and ETF. For a US owner the default regime taxes distributions and gains punitively with an interest charge for the years the value built up. Two elections fix it, and both need annual information the fund may not produce for you. Holding the same exposure through US-domiciled funds usually avoids the problem entirely. See PFICs and Canadian mutual funds.

How many days can I spend in a country before I become tax resident?

It depends on the country, and a day count is only ever the start. Many use a threshold in a tax year, some also look at averages across several years, and some have no day test at all and decide on where your home and life are. Two countries can both conclude you are resident, which is what the treaty tie-breaker exists to settle. Counting days without checking the tie-breaker is how people end up filing as resident nowhere. See the residency tie-breaker.
