Definition

A separate company in the foreign country, which ring-fences liability and creates withholding, transfer pricing and a second set of accounts.

Where the money is

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 the two systems can differ

Where two systems classify the same thing differently, the tax result can be worse than either system intends — a deduction with no matching inclusion, or income taxed in two hands. Anti-mismatch rules now neutralise several of those outcomes rather than leaving them available.

Where you will meet it

Subsidiary comes up in the pages below, which is usually a faster route than the definition itself — the term is only useful once you can see which filing it changes.

What to do with it

Recognising Subsidiary in your own paperwork is the useful skill. Working out which side of it you fall on is a short call. Ask before the move rather than after it, because most of the useful options expire on the date.

We keep these entries short and mechanism-level on purpose: enough to recognise the issue in your own paperwork, and not so much that the page reads as advice about a situation we have not seen.

If you came here for international tax accountant, this is where it is dealt with. The subject is subsidiary, and the page covers who it reaches, what then has to be filed, and what we charge to do the work.

Files that look like this one

Case study 1

An intercompany charge with nothing behind it

A parent had been charging its overseas subsidiary a monthly fee for management and systems, set years earlier and never revisited, with no agreement and no description of what was delivered. The subsidiary's authority disallowed part of the deduction. We identified the services actually provided, built the price from the cost of delivering them, wrote the agreement to match, and gathered evidence of delivery for the open years. The engagement produced a documented pricing basis and a restated charge the subsidiary can support going forward.

Case study 2

Mixing loan and share capital in a new subsidiary

A group was capitalising a subsidiary in a country where profits were expected early. Funding it entirely by loan would have produced interest deductions the local rules would have restricted, plus withholding on each remittance once it reached the parent. Funding it entirely by shares wasted the deduction available. We modelled the mix against the local restriction and the treaty position on interest, documented the terms so the loan looked like what it was, and set out how each part could later be recovered.

Case study 3

Statutory accounts that no longer agreed with group reporting

A subsidiary's local accounts, prepared on the local basis by a local firm, had drifted from the figures the parent consolidated, and the difference had never been explained. It surfaced when the subsidiary's return was examined and its revenue did not match the group's own published segment figures. We built the reconciliation line by line, separated genuine basis differences from errors in the group submission, and corrected what needed correcting. The engagement produced a standing reconciliation the finance team updates each period.

Case study 4

Parent credit support behind a subsidiary's borrowing

A subsidiary borrowed locally on the strength of an undertaking from its parent, and neither company recognised anything for it. The subsidiary's authority took the view that the undertaking was a service the parent had provided and that a price should have been recorded. We set out what the support consisted of, what the subsidiary's borrowing terms would have been without it, and priced the undertaking on that basis for the years concerned. The engagement produced the analysis, a written agreement, and adjustments filed in both countries.

Case study 5

Shares held by the founder instead of the parent

A group discovered that its overseas subsidiary had been incorporated with its founder as the registered shareholder, for speed, and had stayed that way for years while the parent funded and controlled it. Group relief, dividend treatment and the transfer pricing position all assumed a relationship that did not exist on the register. We documented who had actually funded and controlled the company, set out the consequences of transferring the shares to the parent now, and filed on the corrected basis.

Case study 6

A dormant subsidiary that was still an obligation

A group had stopped trading in one country but left the subsidiary in place in case it returned. Local returns, accounts and a director were still required, and the entity had accumulated years of small penalties nobody had opened. We established what was outstanding, brought the filings current, and set out the difference in cost and exposure between keeping the company dormant and winding it up properly. The engagement produced a current filing record and the analysis behind the decision the group then took.

Case study 7

An Assignment Priced Without Counting the Days

Nearly every relief in a mobility file — treaty exemption, residence, social security — is decided by a day count that has to be evidenced. The engagement puts the tracking in place at the start, because it cannot be reconstructed at the end.

Case study 8

Green Card Kept, Moved to Canada — Both Returns Still Due

Holding a green card does not end the US filing obligation, and living in Canada starts a Canadian one. The engagement fixes residence under the treaty tie-breaker, then decides which return the relief is claimed on so the two do not contradict each other.

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.

Importers, Exporters & Manufacturers

Related-party purchasing, customs value versus transfer price, and foreign-affiliate structures put trading businesses inside the s.247 documentation rules.

Goods crossing a border move the tax question from income to indirect: registration thresholds, place of supply, the customs value and the transfer price between related entities all have to agree with each other. When they do not, the adjustment arrives from two authorities at once and each one uses the other's number.

Asked next about Subsidiary

Will dividends from our foreign subsidiary be taxed twice?

The subsidiary pays tax on its own profit where it operates, the country it sits in may take a slice of the dividend at source, and the parent's country then looks at the receipt. Whether that adds up to double taxation depends on the relief available to the parent, which is usually limited by country and by category of income. The point to take from it is that the dividend route has to be priced before the group commits to it, because relief that is unavailable cannot be created afterwards by rewriting the paperwork.

Do we need transfer pricing documents for a small subsidiary?

Size changes what the documentation has to look like, not whether the transactions have to be priced. A subsidiary that buys from the parent, uses the parent's systems, or has its costs met centrally has related-party dealings, and those have to be on terms independent parties would accept. Formal reporting thresholds are a separate question from the underlying obligation. The least elaborate version of this is an intercompany agreement, an explanation of how the price was arrived at, and enough evidence to show the work was actually done.

Should we fund our subsidiary with a loan or share capital?

Both are used, and the mix is the real decision. Interest is generally deductible where the subsidiary operates, which is why groups lend, but the deduction is usually limited by rules on how much debt an entity can carry relative to its equity, and interest leaving the country commonly attracts withholding. Share capital carries none of that and none of the deduction either, and getting it back out again is a corporate act rather than a repayment. The answer follows from the subsidiary's profitability, its local rules, and how the group expects to recover the funds.

Does our liability really stop at the subsidiary?

For general trading liabilities, that ring-fence is the main reason a separate company is used. Tax is where it leaks. Directors can be personally exposed for unremitted payroll and indirect taxes in many systems, the parent can be drawn in where it has given credit support behind the subsidiary's borrowing, and a parent support undertaking is itself a related-party transaction that has to be priced. So the protection is solid for commercial claims and narrower than expected for tax. That distinction is worth checking in each country the group operates in.

Who is responsible for the subsidiary's local accounts and returns?

The subsidiary is a separate person, so the obligations are its own and fall on its directors, whoever prepares the numbers. That has two practical consequences for a group. The local statutory accounts are prepared on the local basis and will not match the figures the subsidiary reports into group consolidation, so a reconciliation has to exist and be kept current. And a local director appointed for convenience is carrying real filing and payment responsibility, which is worth explaining to that person before they sign anything.

Can we charge management fees to our overseas subsidiary?

Yes, and it is ordinary practice, but the charge has to survive two questions in the subsidiary's country: was a service actually provided to this company, and would an independent party have paid this for it. A fee set as a share of turnover with nothing describing what was delivered fails the first. The deduction is also often reduced by withholding on the fee leaving the country and by limits on related-party charges. What makes such a charge stand up is a written scope, a price built from the cost of delivering it, and evidence of delivery.

What is a totalization agreement and how do I use one?

A social security agreement that stops you contributing to two systems for the same work, and lets periods in both count towards benefit eligibility in either. Which system you stay in depends on the agreement's rules for your situation — a seconded employee usually remains in the home system for a set period, a locally hired one usually joins the host system. You evidence it with a certificate of coverage obtained before or shortly after the assignment starts. See certificates of coverage.

Branch or subsidiary — which should we use to expand?

A branch keeps one taxpayer: results consolidate at home, losses are usable sooner, and the exposure is that the branch is a permanent establishment whose profit the host country taxes, sometimes with a branch tax on repatriation. A subsidiary is a separate taxpayer with limited liability and local rates, at the cost of withholding on dividends home and transfer pricing on everything between them. The deciding facts are usually expected losses, liability and exit plans. See branch against subsidiary.
