Definition

A foreign operation that is the same legal person as the head office, so its results consolidate — at the cost of exposing the parent to the foreign system.

Why it matters

These concepts are triggered by activity rather than by intention. A business is usually already over the line by the time somebody looks it up.

Where cross-border trouble starts

The same word can describe a status in one system and a transaction in the other. Reading it as the wrong kind of thing is how a file ends up answering a question nobody asked while leaving the real one open.

Putting it to work

Where Branch affects your own position, the answer depends on dates and documents rather than on the definition — which is why we start with those. Bring last year's returns and we will tell you what is missing.

These entries stop at the point where the answer starts depending on your own facts. Past that line a page cannot be right for everyone, and being confidently wrong in general is worse than being useful in outline.

Case study 1

A project office that had crossed into a taxable presence

An engineering business had staff on a client site in another country for a long stretch of a contract, under an office it described as coordination only. Its people were supervising the work and agreeing variations. We wrote up what each person actually did and for how long, concluded that the activity had created a taxable presence from a date part-way through the contract, prepared the attribution of profit from the project accounts, and filed from that date. The engagement produced a documented position and a filing history that matched it.

Case study 2

Branch registered for regulatory reasons and never filed for tax

A company had registered a branch in order to hold a licence and assumed registration was the whole obligation. No returns had been filed for several years, though the branch had modest revenue. We established which years were open, reconstructed branch results from the group ledger, prepared the outstanding returns in order from the earliest, and set out the exposure on penalties and interest before anything was submitted. The engagement produced a complete filing history and a monthly routine, so the branch accounts no longer have to be reconstructed.

Case study 3

Choosing a branch for the loss-making phase and pricing the exit

A software business expected several years of deficit in a new market before anything came back. We set out the difference between holding those losses inside a foreign company until it turned profitable and taking them into the group's own results as they arose, and the client opened a branch. In the same engagement we estimated what converting to a local company would cost once the operation was profitable, and recorded the assumptions, so that decision could later be made against an analysis rather than an impression.

Case study 4

Head office costs charged to a branch and questioned on examination

A foreign authority asked why a share of head office salaries, software and premises had been charged against branch profit. Nothing had been written down at the time beyond a proportion applied in the ledger. We identified what each cost actually supported, built an allocation basis from headcount and usage evidence, and restated the charge for the years under examination on that basis. Part of the original charge did not survive. The engagement produced the allocation methodology, the evidence behind it, and the response to the authority.

Case study 5

Closing a branch without leaving an open year

A company had stopped trading through its foreign branch and wanted the registration removed. Final returns were outstanding, assets remained on the branch ledger, and staff had been employed through the closing months. We sequenced the work: the employment obligations first, then the closing return dealing with the disposal of what the branch held, then the application to come off the register once the authority had nothing open. The engagement produced a closed year, a clean deregistration, and a file showing the order in which each step was cleared.

Case study 6

The same branch profit taxed in both countries

A branch's profit had been taxed where the work was done and again in the company's own return, with relief claimed for only part of the foreign tax. The difficulty was that each system measured branch profit differently, so the amounts did not line up year by year. We reconciled the two computations, identified where the difference was timing and where it was a genuine disallowance, and restated the relief claim on the reconciled figures. The engagement produced the reconciliation schedule and an amended claim.

Case study 7

Deduction at Source on Deposit Interest, Recovered

Where the treaty rate is lower than what was deducted, the difference comes back through a return rather than at source. The file establishes entitlement and files for the years still open.

Case study 8

Paying a Dividend Up to a Foreign Parent

The withholding rate depends on the treaty, on the size of the holding, and on whether the parent is the beneficial owner rather than a conduit. Establishing all three before the payment is what secures the lower rate at source.

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.

Technology & SaaS

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.

Branch: further questions

Does opening a branch abroad make our whole company taxable there?

Not the whole company, but the exposure runs to the company itself rather than to a separate entity, which is the part people miss. A branch is the same legal person as the head office, so the foreign authority assesses your company, asks your company for records, and can look at your company's affairs to work out what belongs to the branch. What is taxable is the profit attributable to the activity carried on in that country. What is exposed, procedurally, is the entity. That is the trade for being able to consolidate the results.

Can we set branch losses against head office profits?

Generally yes, and it is the main reason a branch is chosen for a loss-making start-up phase abroad. Because the branch is not a separate person, its results form part of the company's own, so early losses reduce profit at home in the year they arise rather than waiting inside a foreign company until it becomes profitable. The cost sits at the other end: once the operation is profitable that profit consolidates too, and moving it into a local company later is a transaction with its own consequences. The choice is about timing as much as tax.

When does our activity in another country become a taxable branch?

When it crosses from preparation into doing business there, judged by what people actually do rather than by what the contract or the sign on the door says. A fixed place used for the business, staff with authority to commit the company, work carried out over a sustained period on a site — these are the facts that decide it, and they can be satisfied without anyone registering anything. Businesses are usually across the line before they look it up. The useful exercise is to write down what your people do in that country, month by month, and test that.

What accounts does a foreign branch need of its own?

Enough to answer the only question the foreign authority is really asking: how much of the company's profit belongs to the activity in its country. In practice that means a ledger for the branch that reconciles to the company's own accounts, a basis for any head office costs charged in, and support for the revenue treated as earned there. Keeping the branch inside the group ledger and extracting a figure at year end is where files come apart, because the extraction has to be explained again every time somebody asks.

Is turning our branch into a local company a taxable event?

Usually it is treated as a transfer of the branch's assets and business to a new person, which is exactly the kind of event tax systems price. Both countries have a view: the foreign one on what left the branch, the home one on what the company disposed of. Relief may be available, and it generally depends on the form of the transaction and on filings made at the time rather than afterwards. This is why the conversion cost is worth estimating when the branch is opened, not when the operation has become valuable.

Is there a tax on sending branch profits back to head office?

Several systems impose a charge on branch profits intended to match the withholding a local company would suffer on a dividend, so that the choice between a branch and a subsidiary is not driven by that difference alone. Whether it applies to you, and at what point it bites, depends on the country and on the treaty. Because a branch has no dividends, such a charge is usually computed on a measure of profit rather than on an actual transfer, which surprises businesses that have left the funds in place.

Should I use a branch or a subsidiary abroad?

A branch is the same legal entity operating in another country, so its profits and losses sit with the parent and it is taxed there as a permanent establishment. A subsidiary is a separate company, taxed in its own right, with dividends and withholding on the way home. Losses, repatriation cost and liability usually decide it, and the answer differs by country pair. See branch vs subsidiary.

What counts as foreign income, and what is a foreign tax?

Foreign income is income sourced outside the country you are filing in — where the work was done, where the property sits, where the payer is resident, depending on the type. A foreign tax, for credit purposes, is a levy imposed by another country that functions as an income tax and that you were legally required to pay. Consumption taxes, property taxes and most social contributions are not, however real the cost. Sourcing is decided by rule, not by which bank received it. See the foreign tax credit.
