Answer

Placing personnel in a client's country is the classic service permanent-establishment fact pattern, and the staffing firm — not the client — carries the exposure. The first foreign obligation in this sector is rarely income tax, which is why it is discovered late.

The rule for this sector

Two countries tax slices of one gain: C$109,889 and C$62,111 on this apportionment. Where their taxing points differ — grant, vest, exercise or sale — the credit can arrive in a year the other country is no longer taxing, which is the mismatch to plan around.

Cross-border tax case studies

Case study 1

Presence record rebuilt for consultants placed across three countries

The firm had placed consultants on client sites in three countries over several years without keeping any central record of who had been where. We rebuilt the presence history from timesheets, invoices and travel bookings, mapped it against the services provision in each treaty, and identified the dates on which a taxable presence arose in two of the three. The engagement produced a dated presence register the firm now maintains as placements are booked, corporate registrations in the two countries concerned, and a written assessment of the third explaining why no filing is required on the current pattern of work.

Case study 2

Placement fee withholding reduced by documenting the position in advance

A client in one country had been deducting from every placement invoice, and the firm had written the deduction off as unrecoverable. We established that the fee was business profit of the firm and that the treaty limited that country's right to tax it in the absence of a presence there, then assembled the residence documentation the payer required before it could apply the reduced rate. The work produced the treaty position lodged with the payer before the next invoice, a repayment claim for the deductions already taken, and a standing task so the documentation is renewed each year rather than allowed to lapse.

Case study 3

Voluntary filing made for years in a country never registered in

Consultants had worked in one country long enough to create a presence there, and no return had ever been filed. We settled the start date from the engagement records, computed the profit attributable to the work performed in that country, and quantified the payroll that should have run alongside it. The engagement produced a disclosure made before any enquiry had opened, the outstanding corporate and payroll filings for the open years, and an attribution method agreed internally so the following year could be filed on time and on the same basis as the years disclosed.

Case study 4

Payroll registered where the client directed the consultants daily work

A long placement had drifted into a pattern where the client set the consultants' hours, tasks and supervision while the firm continued to payroll them at home. That country treats such an arrangement as making the client the economic employer, which removes the short-assignment relief the firm had assumed applied. We documented the working pattern, established the date the relief ceased to be available, and registered the firm for employment withholding there. The engagement produced backdated payroll filings, corrected home-country reporting for the consultants affected, and a test the firm now applies before any placement is extended.

Case study 5

Rotation patterns compared before a multi-year framework was signed

The firm was about to sign a framework agreement to supply consultants to one client in a country where it had never filed. We modelled the presence the framework would create under the services provision of that treaty, distinguished the counting of personnel days from the continuity of the project itself, and set out what each staffing pattern would oblige the firm to do. The result was a written comparison of three rotation patterns and their filing consequences, contract clauses covering withholding and documentation, and a decision to register in that country from the outset rather than manage the presence down.

Case study 6

One engagement split between two countries and its profit attributed

A single client engagement was being delivered by consultants sitting in two countries, invoiced from one, with all profit reported at home. Both countries had grounds to tax part of it and the firm had no basis prepared for dividing it. We analysed the functions performed and the people deployed in each location, built an attribution from the firm's own time and cost records, and tested it against what each authority would expect to see on enquiry. The engagement produced a documented attribution method, returns filed on that basis in both countries, and a credit claim at home matching the split rather than the invoicing.

Selling Into the US Without an Entity, and Filing in Several States

State obligations are set by each state, and a treaty does not reach them. The review measures activity against each state's own thresholds and separates the states where registration is required from the ones where it is not.

Expanding Abroad — Branch or Subsidiary, Decided on the Numbers

The choice sets the tax on profits, the treatment of early losses, and what it costs to take money home later. The file models all three across the first years rather than deciding on the incorporation cost alone.

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.

Global E-commerce & Marketplaces

Cross-border tax for sellers shipping worldwide: marketplace withholding, foreign registrations and inventory nexus handled before they become audits.

Marketplaces withhold, remit and report in their own right, so the tax position of a single sale is decided by where the stock sat, where the buyer was and which platform collected — not by where the company is registered. We reconcile the platform's own filings against the returns before either is submitted.

Questions that come up on IT staffing firms

Our consultants sit on a client site abroad — do we owe tax there?

Possibly. Placing your own personnel on a client's premises in another country is the fact pattern most treaties address through a services provision: where your people perform services in that country on a project, or on a set of connected projects, over a sustained period, the firm is treated as having a taxable presence even without an office. The measure is normally the presence of your personnel rather than the client's own activity, and days spent by different consultants on the same engagement are usually added together. The practical consequence is a corporate filing and an allocation of profit to that country.

Who is responsible when a client withholds on our placement fees?

Commercially the client deducts it, but the tax is yours. Withholding is a collection mechanism applied to your income, and the firm bears it unless the contract shifts the cost. Two things follow. Where a treaty limits or removes the other country's right to tax your fee, the relief normally has to be established with the payer before payment, using documentation the payer can rely on; afterwards it becomes a repayment claim against that country's revenue authority instead, which takes far longer. And where the deduction was correct, the route to recovery is the credit in your own corporate return, which depends on the income being foreign-sourced under your home rules. A gross-up clause moves the cost but does not change whose tax it is.

We never registered in the countries our consultants worked in — what now?

Start by establishing the facts rather than the liability. For each country, work out which consultants were present, on what dates, on which engagements, and who paid them. That record decides everything else: whether a services presence arose, from what date, whether payroll was due from the first day, and which years remain open. Most countries have a route for coming forward before they contact you, and the terms are materially better than those available once an enquiry has started. The order of work matters, because a disclosure made before the facts are settled tends to be reopened. We rebuild the presence record first and file second.

Does a service permanent establishment depend on the client or on us?

On you. The services provision looks at your enterprise carrying on business in that country through your people. The client's own tax position is largely irrelevant to it, and a client with no exposure of its own can still be the site of one for its supplier. That is why staffing is treated differently from a straightforward sale of goods or a licence of software: what is being supplied is people, and the people are physically there. It also means the exposure travels with the engagement rather than with the contract's governing law or the place the invoice happens to be raised from.

Do we have to run payroll where a consultant is placed?

Often yes, and the question usually arises before the corporate one. Employment withholding in most countries attaches to work performed within the territory, and it can apply from the first day even where a treaty ultimately relieves the employee from tax there. Where the firm has a taxable presence in that country, or where the client is treated as the economic employer because it directs the consultant's daily work, the relief that would otherwise protect a short assignment tends to fall away. The two questions — is the firm taxable, is the payroll due — have different tests and different start dates, and each has to be answered separately for every country a consultant is placed in.

Can we structure a placement so it does not create a presence abroad?

Sometimes, but not by drafting alone. What decides the outcome is the duration and continuity of your people's presence, whether they work under your direction or the client's, and whether anyone there habitually concludes contracts for the firm. Those are facts, and revenue authorities test them against timesheets, site records and immigration data rather than against the contract. There are legitimate approaches — shorter rotations, engaging an employer of record in that country, or simply registering and filing properly — and the right one depends on how long the client relationship is expected to run. A structure adopted after a presence has already arisen does not undo the earlier years.

Is my Indian provident fund or PPF still tax-free now that I live abroad?

The exemption is an Indian one, and it does not travel. Your new country of residence taxes worldwide income under its own rules, and several — the United States in particular — may treat the annual growth in a foreign retirement or savings plan as currently taxable and separately reportable, whether or not you withdrew anything. So an account that is genuinely tax-free in India can be a taxable, reportable asset where you now live. See Indian pensions received abroad.

Do I get credit for all of the foreign tax I paid?

Only up to your own country's tax on that same income, and only for tax you were legally obliged to pay. Two consequences follow. Living somewhere that taxes you more heavily than your residence country does leaves an excess that becomes a carryover rather than a refund. And withholding suffered above the treaty rate is not creditable — the route back to that money is a refund claim in the country that took it. See claiming the credit.
