Foreign Corporate Tax Services in Canada

A foreign corporation becomes subject to Canadian corporate income tax when it has a permanent establishment in Canada, which can include a fixed place of business, a dependent agent authorized to conclude contracts, or a construction or installation project lasting beyond the period specified in the applicable treaty — commonly twelve months. Even without a permanent establishment, foreign corporations may be subject to Canadian withholding tax on certain Canadian-sourced income. The Tax Whiz assesses your specific activities to determine exactly which Canadian obligations apply.
Part XIII withholding applies at 25% on most Canadian-source passive payments to non-residents, frequently reduced by treaty.

A branch is a direct extension of the foreign corporation in Canada, and the foreign parent is directly liable for Canadian taxes. A Canadian subsidiary is a separate legal entity subject to Canadian corporate tax on its own income. Each structure has different tax implications, and the right choice depends on your business model, treaty position, and long-term plans. The Tax Whiz advises on the optimal structure for your Canadian entry.

Canada’s branch tax is an additional tax on foreign corporations operating through a Canadian branch, intended to approximate the withholding tax that would apply if profits were repatriated as dividends from a Canadian subsidiary. The branch tax rate is 25% of after-tax branch profits not reinvested in Canada, though this rate is often reduced significantly under Canada’s tax treaties. The Tax Whiz manages branch tax planning and compliance for foreign corporations across Canada.

A foreign corporation making taxable supplies in Canada may be required to register for and collect GST/HST, even in the absence of a physical presence, in some circumstances. The registration threshold is $30,000 in Canadian taxable supplies in any 12 months. Failure to register when required results in unremitted tax liability plus interest and penalties. The Tax Whiz assesses your GST/HST obligations and manages all required registrations and filings.

Transactions between a foreign corporation and its Canadian subsidiary must be conducted at arm’s length prices and supported by contemporaneous transfer pricing documentation. Failure to meet these documentation requirements exposes the corporation to CRA adjustments and significant penalties. We advise on what documentation your situation requires, review what you have, and bring in a specialist where a formal study is needed.

Not necessarily. A foreign corporation can sell into Canada, sign Canadian contracts, hold Canadian customers, and be paid in Canadian dollars without ever incorporating here. Whether Canadian income tax applies turns on whether you have a permanent establishment, not on whether you’ve set up a Canadian entity.

Incorporation is usually driven by commercial reasons: limiting liability, employing people locally, satisfying a customer or lender who requires a Canadian counterparty, or committing to a long-term presence. Those are legitimate reasons. What they aren’t is a tax prerequisite, and incorporating “to be safe” often creates obligations that the treaty position didn’t require.

A Canadian subsidiary is a separate taxpayer, and it comes with a standing compliance load: its own T2 return every year whether or not it was profitable, a business number and CRA program accounts, extra-provincial registration in each province where it carries on business, and GST/HST registration where applicable.

It also brings transfer pricing into play. Every transaction between the subsidiary and its foreign parent, management fees, intercompany loans, licensing, cost sharing, goods at anything other than arm’s length prices, has to be priced as if between unrelated parties and supported by contemporaneous documentation. Distributions back to the parent are subject to withholding tax, often reduced by treaty.

None of this is prohibitive. But it’s an ongoing annual cost, and it’s worth knowing before the decision rather than after.

Yes. A branch isn’t a separate company, the foreign corporation carries on business in Canada directly, files a Canadian return reporting the income attributable to the branch, and remains liable for the tax itself.

The practical differences: a branch keeps everything on one balance sheet and can make early Canadian losses usable against the parent’s position, depending on the home country’s rules. Against that, Canada applies a branch tax on after-tax branch profits not reinvested in Canada, which treaties frequently reduce, and the parent’s own liability is directly exposed rather than ring-fenced in a subsidiary.

Branches often suit a defined project or a first contract. Subsidiaries often suit a permanent Canadian business. The determining factors are usually duration, liability appetite, and where losses are most useful.

Usually yes, and this is one of the most common and expensive misunderstandings we see.

A non-resident corporation carrying on business in Canada is generally required to file a T2 return even where a treaty exempts its profits from Canadian tax. The return is how the exemption is claimed; it includes the schedule that discloses the treaty-based position. Skipping the filing because “no tax is owing” leaves the position unstated, exposes the company to late-filing penalties, and in some circumstances leaves the reassessment window open indefinitely.

Filing a nil or treaty-exempt return is inexpensive. Not filing one is not.

A permanent establishment is a fixed place through which a business is carried on: an office, branch, factory, workshop, construction site, or a warehouse you control. It also extends to a dependent agent in Canada who habitually exercises authority to conclude contracts on your behalf.

If you have one, Canada can tax the business profits attributable to it. If you don’t, and your company is resident in a treaty country, your business profits are generally outside Canadian income tax. The precise tests come from the treaty between Canada and your country of residence, so the answer genuinely differs depending on where your company is resident.

Generally no. Selling into Canada remotely, online, or through an independent distributor acting on its own account does not by itself create a permanent establishment. Revenue from Canada is not the trigger.

What changes the answer is presence and authority: staff or contractors performing work inside Canada, a fixed location here, inventory in a facility you control, or an agent who habitually binds you to contracts. Note that GST/HST obligations can arise even where income tax doesn’t, the two regimes have different tests and are assessed separately.

It can, depending on what that employee does. Someone doing internal or back-office work from their own home is a different case from someone who meets clients, negotiates terms, or concludes contracts in Canada. Contract authority is the factor that most often decides it.

Under the Canada-US treaty there are additional duration-based tests that can create a permanent establishment through the provision of services in Canada, even without any fixed office. If an employee has relocated to Canada, whether by design or because you found out afterwards, the position should be confirmed before the next filing deadline.

Project-based work is treated differently, and duration is usually the deciding factor. Most treaties provide that a building site or installation project becomes a permanent establishment once it lasts beyond a specified period.

Two things catch companies out. The clock generally runs on the site, not on any individual’s time there, so rotating crews through doesn’t reset it. And where a project is split across related entities or contracts covering the same site, the periods may be aggregated rather than counted separately. Multi-phase work scoped as separate contracts frequently ends up counted as one.

It depends on whose facility it is and what happens there. Using a genuinely independent third-party logistics provider on arm’s length terms is different from leasing dedicated space you control.

Storage and delivery of your own goods is treated as auxiliary under many treaties and may not create a permanent establishment on its own. But where the Canadian location also fills orders, handles returns, provides customer service, or functions as an operating hub, the auxiliary characterization becomes much harder to sustain, and if the arrangement includes an agent with authority to conclude sales, it can be enough by itself.

Regulation 105 requires that 15% be withheld from payments made to a non-resident for services rendered in Canada, and remitted to the CRA.

It applies to fees, commissions, and similar amounts for services physically performed in Canada. It does not apply to goods, or to services performed entirely from outside Canada. Critically, it applies whether or not the non-resident has a permanent establishment here; being treaty-protected doesn’t remove the withholding obligation, it only creates grounds to apply for relief from it.

The withholding is not a final tax. It’s a prepayment: the non-resident files a Canadian return, reports the income, and either recovers the excess or pays the difference.

The payer. The Canadian business making the payment must withhold and remit, and is liable for any shortfall plus penalties and interest, regardless of what the contract says about who bears the cost.

This lands badly on both sides. Canadian payers often discover the obligation when the CRA raises it on review, by which point the money has been paid out in full and recovering it from the consultant is a commercial problem rather than a tax one. Non-resident consultants expect to invoice and be paid in full. The obligation should be settled in the engagement terms before the first invoice. Payers also have annual information reporting to file on these payments.

Often, yes, but the application must be made in advance of payment.

Where the non-resident is treaty-protected and has no permanent establishment in Canada, a treaty-based waiver can be requested. Where a treaty doesn’t assist, a waiver based on estimated income and expenses can reduce the withholding to something closer to the real liability. Processing takes time, so the application needs to go in well ahead of the payment date rather than alongside it.

Without a waiver, the 15% must still be withheld and remitted, and the non-resident recovers any overpayment by filing a Canadian return, which can leave the cash with the CRA for the better part of a year.

No, different regimes, and mixing them up is common. Regulation 105 covers payments to non-residents for services, typically contractors and consultants. Payments to employees fall under the payroll withholding rules, which have their own requirements and their own relief mechanism for qualifying non-resident employers.

A company sending people into Canada may have obligations under both, depending on whether those people are employees or contractors, and how the arrangement is characterized for tax purposes doesn’t always match what the contract calls it.
