Answer

Foreign employers sending employees into Canada, and the employees themselves. 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

Foreign employers sending employees into Canada, and the employees themselves.

When the rule breaks

Two questions decide it: whether the treaty exempts the employment income, and whether the employer qualifies for the streamlined certification route. Neither is answered by the employee's own visa status.

Who files Regulation 102?
ItemAmount
Gross amount receivedC$35,000
Withheld at source (assumed 21% of gross)C$7,350
Deductible costsC$20,650
Net amount actually earnedC$14,350
Tax on the net amount (assumed graduated result)C$3,875
Difference recoverable by filingC$3,475

Filing on a net basis recovers C$3,475 of the C$7,350 withheld. That difference is the entire reason the elective return exists, and it is lost by not filing.

The figures here are an illustration, not an engagement: amounts are picked so the mechanism is easy to follow, and every rate or threshold is an assumption of the example. Before anything is filed for you, each one is confirmed with the issuing authority for your own tax year.

How to get this moving

The full treatment — who it binds, the deadline, the penalty and the fixed fee — is on Regulation 102 — waiver application. The first call establishes whether there is work to do. Everything after that is quoted.

Cross-border situations we are engaged for

Case study 1

Establishing who had the filing obligation on a two-country project team

A foreign engineering group sent staff into Canada for a commissioning project and assumed one position would cover everyone. Two of the team were employed through a different group company in another country. We took each person separately, matched their employment contract and travel record to the treaty that applied to them, and found the positions were not the same. The engagement produced a per-employee analysis, waiver applications where the facts supported them, and a written instruction to the Canadian payroll setting out which people to withhold from and which not to.

Case study 2

Separating immigration advice from the payroll withholding question

An employee arrived in Canada with a valid permit and an employer who believed the permit settled the payroll treatment. The first task was to unpick that. We set out in writing why the permit answered a different question, then worked the tax position from the employment facts: where the duties were performed, who bore the cost of the salary, and what the treaty said about it. The engagement produced a waiver application supported by the employment documents, and a short note for the employer's file recording why immigration status had not been relied on.

Case study 3

An assignment that had already run for months without withholding

A foreign employer discovered mid-year that a seconded employee had been paid throughout from the home payroll with nothing withheld in Canada. We treated the employer's exposure and the employee's reporting as two pieces of work, in that order. Establishing whether the treaty exempted the employment income came first, because it sized both problems. The engagement produced a documented treaty position, a corrected approach for the remaining pay periods, and a written account of the earlier ones prepared for disclosure rather than left to be found.

Case study 4

Testing whether the employer qualified for the streamlined certification route

A foreign employer wanted to avoid a waiver application for every short visit and asked whether it could certify instead. That is an employer-level question, so the work looked at the company rather than the travellers. We examined its standing with the CRA, its history of Canadian filings and the pattern of assignments it expected to run. The engagement produced a written assessment of whether the route was available to it, the conditions attached, and a decision the employer could take with its own advisers before any employee boarded a flight.

Case study 5

Building the evidence file before the first Canadian pay date

A company with a Canadian contract starting the following month asked what it would need. The answer was documents rather than opinions, so the engagement was front-loaded. We listed what the employment position would rest on, meaning the contract, the secondment letter, the payroll cost allocation and the client agreement, together with the calendar of days and duties that would have to be kept from the first day. The engagement produced a document schedule, a diary template for the assignment, and an application lodged before the payroll ran rather than after it.

Case study 6

A director visiting Canada whose duties were not what the contract said

An employer treated a visiting director as covered by a position taken for its project staff. The travel record told a different story: the visits were board and client work, not the project duties described in the assignment letter. We rebuilt the position from what was actually done in Canada on each trip. The engagement produced a corrected description of the duties, a separate application reflecting them, and a note to the employer explaining that the project team's position could not be stretched over someone doing different work.

Case study 7

Fifteen Per Cent Held Back From a Fee for Services in Canada

A payer must withhold from fees paid to a non-resident for services rendered in Canada, whether or not any tax is ultimately owed. A waiver applied for before the work is invoiced avoids the withholding; after it, the money comes back through a return.

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.

Professional Services Firms

Firms and partners working across borders meet Regulation 105 withholding, PE risk on long engagements and per-country payroll for travelling staff.

A partnership is taxed in the hands of its partners, so one engagement abroad can reach every partner's personal return. The order matters: the waiver is applied for before the invoice, the presence is tracked before it becomes an establishment, and the payroll is registered before the first day worked in the other country.

Regulation 102: further questions

Do I file Regulation 102 or does my foreign employer?

Both have something to do, and it is not the same thing. The waiver of payroll withholding is sought in respect of the employee's income, so the employee's facts drive it: days in Canada, duties performed here, and who bears the cost of the employment. The employer is the party that would otherwise withhold and remit on the Canadian payroll, so it is the employer's obligation the waiver relieves. In practice the application is prepared with both sides' information on the table, meaning the employment contract, the assignment letter and the travel record. Deciding who signs what is the last step rather than the first.

My employee is only in Canada for a short project, does this apply?

Short does not mean exempt. Withholding on employment income earned in Canada is the default whoever the employer is and however brief the assignment, and it is relieved by a waiver or by a certification route rather than by the length of the trip. Two questions decide the position: whether the treaty exempts the employment income at all, and whether the employer qualifies for the streamlined certification route. Neither is answered by how many weeks the assignment runs. Work the answer out before the first Canadian payroll date, because the alternative is withholding on income that may not be taxable here.

Does my work permit mean I do not need a Regulation 102 waiver?

No. Immigration status and tax withholding are decided by different rules and different authorities. A permit says you may work in Canada. It says nothing about whether the income you earn here is taxable in Canada, or whether your employer must withhold from it. The tax question turns on the treaty position for your employment income and on your employer's own standing with the CRA. People are caught by this regularly, having assumed the permit settled everything. Treat them as two separate matters with separate evidence, and do not let the timing of one drive the assumptions of the other.

Who is responsible if withholding was never taken from a Canadian assignment?

The withholding obligation sits with the employer, so that is where the CRA looks first, and it looks for the amount that should have been withheld rather than for the employee's own tax. The employee is not out of it, because the income still has to be reported where it is taxable, but the two exposures are separate and they are resolved separately. Where an assignment has run without withholding, handle the employer's position and the employee's position as two pieces of work. Establishing whether the treaty exempted the income at all usually decides how large a problem either one is.

Can one waiver cover several employees on the same Canadian project?

The analysis is per employee, because the facts that matter are individual: the duties performed in Canada, the days spent here, and the treaty that applies to that person. A project staffed from two countries has at least two positions to establish, even where the assignment letters look identical. What can be shared is the groundwork, meaning the contract with the Canadian client, the project calendar and the description of what the team is actually doing here. Build that once, then apply it person by person. Expect the answers to differ, particularly where someone's home country has a different treaty with Canada.

What does my employer need to give me to support the application?

Start with the documents that describe the employment rather than the trip: the contract of employment, the assignment or secondment letter, the payroll record showing where the salary is actually paid from and borne, and the agreement with the Canadian client. Then the calendar, meaning the dates in and out of Canada and what was done on each. Where the employer is relying on the streamlined certification route, its own standing with the CRA needs evidencing too, and that sits in the employer's file rather than yours. Gather it before the first Canadian pay date. Assembling it afterwards is the same work under pressure.

Is my foreign pension taxable?

Usually in at least one country, and which one depends on the treaty article covering pensions — some give the taxing right to the country paying it, others to where you live, and several treat government service pensions differently again. Withholding at source is common and often reducible by treaty, with an elective return recovering an over-deduction. See the pensions article.

What is TCS on foreign remittance?

Tax collected at source. When a resident individual remits money abroad under the Liberalised Remittance Scheme — or buys an overseas tour package — the bank or seller collects an amount of tax on top and deposits it against your PAN. It is not a cost and it is not a final tax: it appears in your annual tax statement and is set off against the tax on your return, with the excess refunded. The rates and the purposes they attach to have been amended repeatedly, so we confirm them for the remittance year. See LRS limits and TCS.
