Answer

Creation, transfers, distributions and loans are reportable events, and the trust's annual return requires a statement for its US owner and beneficiaries. The obligation is decided by facts rather than by tax owing, which is why a nil position does not remove it.

The rule on who files

Creation, transfers, distributions and loans are reportable events, and the trust's annual return requires a statement for its US owner and beneficiaries. Many foreign retirement, education and family arrangements meet the definition of a trust here.

The carve-out

Two forms, two filers: one reports the US person's transactions with the trust, the other reports the trust's own year — and the US owner is responsible for making sure both happen.

Reporting a foreign trust — who pays, and where?
ItemAmount
Worldwide estateC$3,551,000
Assets situated in the USC$284,080
Proportion of the estate exposed8%
Relief mechanismTreaty credit, pro-rated by the same proportion

The exposure follows the 8% rather than the whole estate, and the treaty relief available to a Canadian estate is pro-rated on the same ratio. That ratio is the number to manage — through how the US assets are held, not through where the owner lives.

The figures here are an illustration, not an engagement: amounts are picked so the mechanism is easy to follow, and every rate or threshold is an assumption of the example. Before anything is filed for you, each one is confirmed with the issuing authority for your own tax year.

International tax reporting, in practice

The subject here is reporting a foreign trust, which is what people mean when they search for international tax reporting. This page covers who it applies to, the filings it produces, and the fixed fee agreed before work begins.

Cross-border situations we are engaged for

Case study 1

An overseas retirement arrangement that met the definition of a trust

The client had left a retirement arrangement behind in the country he came from and had never thought of it as a trust. Many foreign retirement, education and family arrangements meet the definition here, which brings both the owner's own reporting and the trust's year into play. We read the plan documents against the definition, established what the client's interest actually was, and worked out which of the reportable events had already happened. The engagement produced a filing position for the years affected and a description of the arrangement the client can reuse each year.

Case study 2

A foreign trustee who had never heard of the trust's annual return

Two filings were in issue, one for the US person's own transactions with the trust and one for the trust's year, and the US owner is responsible for seeing that both happen. The trustee abroad had no intention of doing anything. We set out what the trust's own return requires, assembled the trust's year from the accounts the trustee would release, and prepared the statements the owner and the beneficiaries need. The engagement produced both filings for the year and a written arrangement with the trustee about what he will provide and when.

Case study 3

A trust settled years earlier with the creation never reported

Creation and transfers are reportable events in their own right, and this trust had been settled and funded long before anyone raised the question. We built a dated history of the settlement, the transfers in and the distributions out, then separated the events that were reportable when they happened from those that recur annually. The work produced a corrective filing plan starting with the creation year, supporting schedules for each event, and a note of the documents that would be asked for if the position is examined.

Case study 4

Advances from a family trust reconstructed as reportable loans

The family had been moving money out of the trust as informal advances for years, repaying some and forgetting others. Loans from the trust are reportable events, so the informality was the problem rather than the amounts. We rebuilt the ledger from bank records on both sides, matched each advance to a repayment where one existed, and characterised the balances that remained. The engagement produced a reconstructed loan ledger, the filings that followed from it, and a simple rule for the family about what has to be documented when an advance is made.

Case study 5

An education savings arrangement abroad held for the children

Parents had opened an education savings arrangement in their home country for children who are US persons, on the view that money set aside for school is nobody's income. The definition of a trust here is wider than that, and the arrangement fell inside it. We established who the owner was, what the children's interests were, and which events in the arrangement's life had been reportable. The engagement produced the filings for the years since it was opened and a statement of what each future contribution and withdrawal requires.

Case study 6

Trustee statements that did not carry what the filings required

Distributions had been reported from the trustee's covering letters, which recorded amounts and nothing else. The owner's own return needs the character of what was distributed, and the trust's annual return has to support the owner and beneficiary statements, so the letters were never going to be enough. We went back to the trust's accounts, rebuilt the schedules behind each distribution, and specified the statement the trustee should issue in future. The engagement produced corrected schedules for the years already filed and a template the trustee agreed to use.

Case study 7

A TFSA That Costs More Than It Saves

Canadian tax-free accounts are not tax-free to a US person, and some of them carry a reporting form of their own. The file is a review of what is held, what each account triggers on the US side, and whether the account is worth keeping once the reporting is priced in.

Case study 8

A Foreign Subsidiary That Nobody Had Been Reporting

Owning a company abroad triggers an information return separate from the corporate return, with its own penalty. The work is the surplus and income computations behind it, which also determine how a future dividend is taxed on the way home.

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.

Cross-Border Real Estate

Foreign property income and sales are taxed in both countries by default; Section 216, FIRPTA and treaty credits are the standing toolkit.

Property is taxed where it sits, which is the one rule no treaty overrides. What the treaty does decide is the credit, the rate on the rent and what happens on the sale — and the clearance certificate on a disposition is applied for before closing, not after the buyer has already held the money back.

More on Reporting a foreign trust (3520 / 3520-A)

Do I file Form 3520 or 3520-A for my foreign trust?

Often both, by different filers and for different things. Two forms, two filers: one reports the US person's own transactions with the trust, the other reports the trust's own year. The US owner is responsible for seeing that both happen, which is the part that catches people out, because the second concerns a trust run by someone else, usually abroad, who has no interest in the question. So the practical task is not only preparing a return but obtaining the trust's year from a trustee who has never been asked for it. Start that conversation with the trustee early. Everything on the trust's side depends on records only the trustee holds.

Is a foreign pension or education plan a trust for 3520 purposes?

Frequently yes, and this is the biggest source of unexpected filings here. Many foreign retirement, education and family arrangements meet the definition of a trust for these purposes even though nobody involved would describe them that way, and the client's own name for the arrangement carries no weight. The way to settle it is to read the plan documents and establish what the arrangement actually is and what interest the client holds in it. If it is a trust, then its creation, the contributions and the withdrawals are all events with a reporting side, and the analysis is worth writing down once so the same conclusion can be reused each year.

Does creating a foreign trust have to be reported in the year it is set up?

Creation is a reportable event in its own right, as are transfers into the trust, so the year of settlement and the years of funding matter separately from any year in which money comes out. This is where old arrangements cause trouble: the trust was settled long ago, nothing was filed, and the events that were reportable at the time have been buried by everything since. The way through is a dated history, covering the settlement, each transfer in, and each distribution and loan out, and then separating the one-off events from the recurring ones. Built once, that history answers most of the questions a later examination will put.

Is a loan from my foreign trust a reportable event?

Yes, loans are reportable events alongside distributions, and treating an advance as merely borrowing is how people persuade themselves there is nothing to file. The difficulty is usually evidential rather than technical, because family advances are made informally, repaid in part, and documented after the fact if at all. What is needed is a ledger reconstructed from records on both sides, each advance matched to its repayment where one exists, and the outstanding balances characterised. Then adopt a rule for the future, that nothing leaves the trust without a note made at the time, because the cost of this work is almost entirely the cost of reconstruction.

The foreign trustee will not file 3520-A, where does that leave me?

Responsible, unfortunately. The US owner is the one answerable for seeing that the trust's own year is reported as well as their own transactions with it, and a trustee abroad declining to help does not shift that. What it does change is the shape of the work. You assemble the trust's year from whatever the trustee will release, prepare the statements the owner and the beneficiaries need, and document what you asked for and what you received. Then put an arrangement in place with the trustee about what will be provided and by when. A trustee who will not file will often still send accounts if the request is specific enough.

What has to go to the beneficiaries from the trust's annual return?

The trust's annual return has to support statements for its US owner and for its beneficiaries, so the return is not a self-contained filing: it produces documents other people rely on for their own returns. In practice that is where trustee cooperation is tested, because a covering letter recording an amount is not a statement. What the beneficiaries need is the character of what was distributed and the trust's own figures behind it. Ask the trustee for that breakdown as part of the year-end routine rather than as a special request, and specify the form it should take, so the statements can be issued without reconstruction.

Do dual citizens have to file US taxes if they live abroad?

Yes. US filing follows citizenship, not residence or where the income arose, and the obligation continues for as long as the citizenship does. Two further obligations travel with it and are keyed to account balances rather than income, so they can apply in a year with no US tax at all: the foreign bank account report to FinCEN, and the specified foreign asset statement with the return. Most people who discover a problem discover it there. See two returns as a dual citizen.

What is the difference between FBAR and Form 8938?

They overlap but are not the same report. The FBAR goes to FinCEN and covers foreign financial *accounts*; Form 8938 goes to the IRS with the return and covers a wider class of specified foreign financial *assets*, with thresholds that vary by filing status and whether you live abroad. Many people must file both for the same accounts, and satisfying one does nothing for the other. See filing both.
