Answer

Requirements differ by jurisdiction and by activity, and several regimes now impose reporting and penalties for failures. One question decides whether this is a filing or a project.

What to check first

Requirements differ by jurisdiction and by activity, and several regimes now impose reporting and penalties for failures. Building substance is an operating decision documented contemporaneously, which is why it cannot be retrofitted.

Where it does not apply

Substance is not a registered office and a local director's fee. It is people who make decisions, records that show them making those decisions, and functions that match the profit.

Substance requirements in practice — what should I check first?
ItemAmount
Income taxed in both countriesC$129,000
Tax paid abroad (assumed 29%)C$37,410
Home tax on the same income (assumed 35%)C$45,150
Credit available (lesser of the two)C$37,410
Home tax still payableC$7,740

The credit absorbs C$37,410 and leaves C$7,740 payable at home, because the home rate on this income is the higher of the two. The balance is real cash and it is due on the home timetable, which is why instalments get raised in the first meeting.

Cross-border tax case studies

Case study 1

Holding company reviewed before an expected group reorganisation

A group holding several overseas subsidiaries through a single intermediate company asked whether that company would withstand a substance question before a reorganisation put its file in front of other people. The work began with what the company actually did: who negotiated the shareholdings, who approved the funding, and where those people sat. The file showed decisions taken at group level and recorded locally. We set out what could be evidenced for each open year and what could not, and the options for the years that were weak. The engagement produced a written position on the company's current standing, an operating plan for the people and premises it would need, and a note of the years already exposed.

Case study 2

Board papers rebuilt so decisions are evidenced as they happen

A company met the formal requirements on paper, but its resolutions arrived drafted and were signed without change. We examined how each decision was actually formed and found the analysis was prepared, discussed and settled elsewhere. The work consisted of rebuilding the board process: agendas circulated ahead of meetings, the underlying analysis given to directors in advance, minutes recording the questions asked, and a record of who attended and from where. The engagement produced a documented decision-making process that runs before the decision rather than after it, together with a file note explaining why the earlier years read differently.

Case study 3

Entity profit compared with the functions actually performed locally

An intermediate company recorded a margin for holding risk that nobody in that country was equipped to assess. The review compared the profit reported against the functions performed, the assets used and the risks that could genuinely be controlled locally. We mapped each element of the margin to a person and asked whether that person existed. Where they did not, we set out the two honest options: hire the capability, or move the profit to where the decisions are taken. The engagement produced a functional analysis the group could put in front of either administration, and a decision recorded with its reasons.

Case study 4

Substance built before launch rather than repaired afterwards

A group planning an overseas operating entity asked for substance advice before incorporation rather than after the first return. We worked through the activities the entity would carry on, the decisions that would have to be taken locally, the people who would take them, and the premises and expenditure that would follow. Requirements differ by jurisdiction and by activity, so the plan was built around what this entity would actually do. The engagement produced a staffing and governance plan tied to the entity's intended functions, and a documentation routine that begins on the first day of trading.

Case study 5

Annual substance reporting reconstructed for a group that had never filed

A group found that a substance reporting obligation attaching to one of its entities had not been met for several past periods. The work started with establishing the facts for each period separately rather than assuming they were the same. We assembled the contemporaneous record that did exist, identified where it was thin, and set out what the entity could properly say about each year. The engagement produced completed reporting on a basis the group could support, a written record of the evidence behind each period, and a schedule of the remaining exposure for the board.

Case study 6

Group collapses a dormant entity rather than resourcing it

An entity in the structure carried on very little activity but had been renewed each year out of habit. Rather than resource it to meet substance expectations, the review asked what it was for. We traced the contracts, the bank accounts and the reporting obligations attached to it, then costed both routes: building the people and premises the activity would require, or winding the entity up and moving the function to where it already sat. The engagement produced a comparison the directors could act on and a step plan for the route they chose, including the filings the wind-up itself triggers.

A Pricing Study That Started With Who Does What

Functions, assets and risks decide which entity should earn the return, and the method follows from that rather than the other way round. Getting the sequence backwards is how a study fails on its first question.

Case study 8

A Foreign Property Form Filed Late, With Penalties Running Daily

The foreign asset return carries a penalty that accrues per day rather than per return, so the exposure grows quietly. Relief is discretionary and it is granted on the reasons given, which means the request is the work rather than the form.

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.

Substance requirements in practice — the questions that follow

Is a registered office and a local director enough substance?

No. A registered office and a director's fee create a presence on paper, not substance. What the regimes look for is people who make the decisions that drive the entity's profit, records that show them making those decisions, and functions in the jurisdiction that match the profit reported there. If the entity earns a margin for holding risk, someone local has to be capable of assessing and accepting that risk. The useful test is whether the arrangement would still make commercial sense if the tax outcome were ignored. A service address and an annual signature do not answer that question.

Can I fix substance problems just before an audit?

Not reliably. Substance is an operating decision that is evidenced as it happens: board papers written before the decision, correspondence showing who was consulted, employment records, premises, expenditure. Recreating those after a question has been asked produces documents dated after the period they describe, which is the first thing a reviewer notices. You can change how the entity operates from today, and that will help future periods. What you cannot do is make the past look different. Where earlier years are weak, the sensible order of work is to fix the operating model first and then deal with the open years on their own facts.

What records prove that decisions were actually made locally?

Papers that show the decision being formed, not merely recorded. Agendas circulated in advance, the analysis the directors were given, minutes that reflect discussion rather than a resolution copied from a template, travel and attendance records, and correspondence showing the questions asked before the vote. The test is whether an outsider reading the file could say who weighed the options. Signed resolutions drafted elsewhere and sent in for signature fail that test, because they evidence execution rather than judgement. Keep the working papers, not only the outcome.

Does every entity in my group need the same substance?

No. Requirements differ by jurisdiction and by activity, so the starting point is a list of what each entity actually does and where it does it. A holding entity, a financing entity and an operating entity are measured against different expectations, and the same activity can be treated differently in two countries. Build the list entity by entity and activity by activity rather than by group policy. Where an entity carries on no relevant activity at all, the real question is whether it needs to exist, and that is often a cheaper answer than resourcing it.

Who is supposed to be making the decisions on paper?

The people who are in fact making them. Problems start when the persons named in the constitutional documents are not the persons whose judgement drives the entity. If the group finance function decides and the local board ratifies, the records will show that, and the substance analysis follows the records rather than the intention. The fix is either to move the decision to the people named or to stop describing the entity as directed where it is not. Both are operating decisions rather than drafting ones, which is why the answer usually involves changing a reporting line rather than a document.

What happens if my substance reporting is wrong or late?

Several regimes now attach reporting obligations to the substance rules and penalties to failures, and some provide for the information to reach other tax authorities. So a defective return is not only a local exposure; it can put the same facts in front of a second administration that is assessing treaty entitlement or the taxation of the same profit. Treat the reporting as part of the substance work rather than a downstream form. Where a return has already gone in on a weak basis, establish exactly what was said before deciding how to correct it.

Is moving money between my own accounts in two countries taxable?

Moving your own capital between your own accounts is not itself income, so the transfer is not what creates tax. What can create tax or reporting is the income the money earned before it moved, a foreign-exchange gain on certain holdings, and the reporting obligations the balances themselves trigger — foreign account and asset reports keyed to balances rather than income. Remittances out of some countries also need certification before the bank will send them. See foreign account reporting.

Do NRIs pay tax on money sent to India?

Sending your own funds to India is a transfer of capital, not income, so the remittance itself is not taxed. What is taxable is income the money then earns in India — interest, rent, capital gains — under the rules for the account type it sits in. Sending money out of India is the direction that needs certification before the bank will act. See NRE, NRO and FCNR accounts.
