Answer

Canadian corporations, partnerships, trusts and individuals whose reportable transactions with related non-residents exceed the filing threshold. 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

Canadian corporations, partnerships, trusts and individuals whose reportable transactions with related non-residents exceed the filing threshold.

The exception that catches people

This return is the transfer-pricing risk map the CRA reads first. It asks whether documentation exists, so answering it honestly is often the moment a group discovers its intercompany pricing has never been supported.

Who files Form T106?
ItemAmount
Current account, highest balanceUS$3,000
Savings account, highest balanceUS$6,000
Account held with a relative, signature authority onlyUS$6,000
Aggregate tested against the thresholdUS$15,000
Reporting threshold (verified, FinCEN)US$10,000

The aggregate of US$15,000 exceeds the US$10,000 threshold, so all three accounts are reported — including the one that is not the filer's money, because signature authority counts.

Example figures throughout, selected to make the rule visible, with rates and thresholds assumed for the demonstration. Your actual filing uses figures confirmed with the issuing authority for your tax year.

Where to go from here

The full treatment — who it binds, the deadline, the penalty and the fixed fee — is on T106 — non-arm's-length transactions. Ask before the move rather than after it, because most of the useful options expire on the date.

Cross-border tax case studies

Case study 1

A new controller finds intercompany charges nobody had reported

The Canadian company had been paying its foreign parent for management support since incorporation and had never filed the information return of non-arm's-length transactions. The work started with the intercompany ledger rather than the financial statements, sorting the charges into the categories the return asks for and totalling them year by year to see which years fell inside the reporting. The engagement produced a filed return for each affected year and a schedule mapping every intercompany entry to the category it was reported under, so the mapping can be reused.

Case study 2

A funding balance that brought a quiet year into reporting

The group traded almost nothing between its companies, which was why the return had never been considered. What it did have was a loan from the parent and interest accruing on it. Financing of that kind is reportable, so the year sat inside the filing requirement despite the absence of trade. We established the balance and the interest charged for each period from the intercompany accounts. The engagement produced returns for the years concerned and a note explaining which reporting categories the amounts fell into and why.

Case study 3

Answering the documentation question honestly for the first time

The group had filed the return for years, ticking the documentation question without much thought. Asked to look at it properly, we could find nothing written down that supported the pricing of the services moving between the companies. Rather than change the answer quietly, the order of work was reversed: build the pricing analysis first, then file on the basis of it. The engagement produced a documented basis for the intercompany service charges and a return whose answer on documentation is now accurate.

Case study 4

A partnership that had never thought of itself as international

The firm recharged professional support from an affiliated practice abroad and assumed the reporting applied only to corporate groups. It does not: partnerships file on the same test as companies where their dealings with related non-residents exceed the threshold. We examined the relationship between the two practices to confirm they were not dealing at arm's length, then quantified the recharges for each period. The engagement produced filed returns for the periods in scope and a written statement of the relationship analysis those filings rest on.

Case study 5

Cost-only recharges that still had to be reported and supported

The client had charged a related non-resident at cost, reasoning that with no profit there was nothing to report. The return asks what the dealings were, not whether they made money, so the years were reportable. The more useful part of the work was the pricing itself: charging at cost is a position, and it needed a written basis as much as any markup would. The engagement produced the outstanding returns and an analysis explaining why cost recovery was appropriate for those particular services.

Case study 6

Mapping a group structure before deciding what was reportable

Acquisitions had left the client unsure which foreign companies were related to it and which were merely customers. Deciding the reporting question required the structure first, so we built a chart of ownership and control, marked which counterparties were non-arm's-length, and only then totalled the dealings with each of them. Several relationships turned out to be arm's-length and dropped out. The engagement produced a structure chart, a per-counterparty total for each year, and returns for the years the remaining dealings took over the threshold.

A Taxable Presence Created Without an Office

A dependent agent habitually concluding contracts can create a permanent establishment where there is no premises at all. The review tests what the person actually does against what the treaty describes.

Case study 8

Withheld at the Statutory Rate When a Treaty Rate Applied

Where withholding has already gone out at the full domestic rate, the treaty rate is recovered rather than applied. The file establishes entitlement for each payment, then puts the documentation in place so the following year runs at the correct rate from the start.

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.

Investment Funds & Holding Companies

Holding structures live or die on treaty access, beneficial ownership and substance — the MLI's principal-purpose test now sits over every arrangement.

A holding structure is only as good as its reporting. Foreign affiliates, accrued passive income and distributions each carry their own return, and the penalties on those attach to the form rather than to any tax being owed — so a structure that saves tax can still cost money if the information returns are late.

Form T106: further questions

Does my company file T106 for payments to its foreign parent?

That depends on the size of the dealings rather than the size of the company. Form T106 is the information return of non-arm's-length transactions with non-residents, and it is due where a Canadian corporation's reportable transactions with related non-residents exceed the filing threshold for the year. Management charges, goods, services, royalties, interest and loans all count towards it. Two points catch owner-managed groups. Profitability is irrelevant, so a loss-making subsidiary with substantial intercompany dealings still files. And the threshold is tested on the transactions themselves, so one large recharge can bring an otherwise quiet year into the reporting.

Do intercompany loans count towards the T106 filing threshold?

Loans and the interest on them are reportable categories, so yes. This is how groups with almost no trading between them end up filing: the Canadian company has been funded by its foreign parent, the balance sits on the balance sheet, and nothing about it feels like a transaction. A funding balance and the interest charged on it are exactly what the return asks about. It is worth examining the intercompany accounts rather than the sales ledger when deciding whether you are inside the reporting, because the amounts that take a group over the threshold are frequently financing rather than trade.

Do partnerships and trusts file Form T106 too?

Yes. The return is not confined to corporations: Canadian partnerships, trusts and individuals file it as well, where their reportable transactions with related non-residents exceed the threshold. In practice this catches structures nobody thought of as international. A partnership that recharges support from an affiliated foreign firm, or an individual dealing with a company they control abroad, sits in the same position as the subsidiary of a multinational. The test looks at the relationship between the parties rather than at the legal form of the Canadian one, so the entity type is the wrong place to go looking for an exemption.

Do we file T106 if the intercompany charges carried no markup?

Yes. The return reports that the transactions happened and what they amounted to; it does not ask whether a profit arose on them. Charging at cost changes the transfer-pricing analysis, and it may well be the right answer for certain services, but it does not take the dealings out of the reporting. Nor does it settle the pricing question: cost with no markup is a position that needs support like any other, and the return is where the CRA first sees that the dealings exist at all. Treat a no-markup recharge as reportable, and as something you should be able to justify.

Does Form T106 ask whether we have transfer pricing documentation?

It does, and that question is the reason the return deserves care. Form T106 is the transfer-pricing risk map the CRA reads first: it sets out who you deal with abroad, in which categories, for how much, and whether the pricing is supported by documentation. For many groups, answering that last question honestly is the moment they discover their intercompany pricing has never been supported by anything written down. The useful response is not to soften the answer but to fix the underlying position, so the following year's return can be answered differently and with something behind it.

Is a T106 needed if we are related but hardly traded?

Where the reportable transactions for the year fall below the filing threshold, the return is not required for that year. Two cautions. The test is applied year by year, so a group can sit outside the reporting one year and inside it the next without any change in the relationships between its companies. And the threshold is measured on the transactions rather than on tax owing, so a nil tax position, a loss, or a dormant year carrying a financing balance settles nothing. Total the intercompany dealings for each year separately before concluding that no return was due.

Does GILTI apply to individuals?

Yes, and it lands harder on them. An individual US shareholder of a controlled foreign corporation has the same inclusion a corporate shareholder does, but without an election gets neither the corporate-level deduction nor credit for the foreign corporate tax already paid — so foreign profit can be taxed at individual rates with no relief for tax the company paid abroad. An election to be taxed as though through a domestic corporation is usually the first thing to model. See Form 5471 and CFCs.

Is GILTI computed at the CFC level or the shareholder level?

Both, in sequence. Tested income, tested loss and the qualifying asset base are measured company by company. They are then aggregated at the US shareholder, which is where the netting of losses across companies happens and where the inclusion, the deduction and the credit are determined. That order matters in practice: a loss in one foreign subsidiary can reduce the inclusion caused by another, but only for a shareholder who owns both. See the GILTI inclusion and Form 8992.
