Canadian Branch Profits Tax Calculator
A foreign corporation operating through a Canadian branch pays regular income tax and then a second tax on the profits it takes out. Work out the Part XIV liability, the allowance for reinvesting in Canada, the treaty exemption still available, and the total effective rate on branch profits.

Disclaimer: Part XIV of the Income Tax Act imposes an additional tax, commonly called the branch profits tax, on a non-resident corporation carrying on business in Canada. Section 219 charges the tax at 25% on the corporation’s amount taxable earned in Canada for the year, which is broadly its after-tax Canadian branch profits reduced by an allowance for any increase in its investment in property in Canada and increased where that investment decreases, so that profits reinvested in the Canadian business are deferred rather than exempted. The tax is intended to approximate the withholding tax that would have applied had the Canadian operations been carried on through a subsidiary paying dividends to its parent. Most of Canada’s tax treaties reduce the 25% rate; the Canada-United States treaty generally reduces it to 5% and provides an exemption for the first CAD 500,000, cumulative over the life of the branch, of the earnings that would otherwise be subject to the tax, reduced by amounts previously exempted. Other treaties differ in both rate and whether an equivalent exemption exists, so the applicable article must be confirmed for the specific country. The branch tax is computed on Schedule 20 and filed with the T2 return. The exemption amount, the treaty rate and the mechanics of the allowance for investment in Canadian property should all be confirmed against the current legislation and the relevant treaty before being relied on; the figures used here are defaults. Whether a foreign corporation is carrying on business in Canada, and whether it has a permanent establishment under a treaty, are separate questions that determine whether any Canadian tax arises at all. This page is general information, not tax advice.
Why There Is a Second Tax at All
A foreign company can serve the Canadian market two ways: through a Canadian subsidiary, or through a branch of the foreign company itself. Those two routes would produce very different tax outcomes if nothing corrected for it.
A subsidiary pays Canadian corporate tax on its profits and then withholding tax when it pays a dividend to its parent. A branch pays Canadian corporate tax and then, without more, could repatriate everything free of further Canadian tax, because a branch does not pay dividends to itself.
Part XIV is that correction. The branch profits tax approximates the dividend withholding a subsidiary would have paid, so the choice between branch and subsidiary is made for commercial reasons rather than because one of them escapes a layer of tax.
This is a second tax, not a higher rate. The branch first pays ordinary federal and Ontario corporate tax on its Canadian income. The Part XIV tax then applies to what is left. Reading the treaty rate as the whole Canadian cost understates it considerably.
Reinvestment Defers the Tax
The base is not simply after-tax profit. It is after-tax profit reduced by the increase in the corporation’s investment in property in Canada during the year. Profits ploughed back into the Canadian business are not taxed now.
The deferral is not forgiveness. Where the investment in Canadian property later decreases, the allowance previously claimed comes back into the base and the tax arrives then. A branch that builds up Canadian assets for a decade and then repatriates the accumulated capital faces the deferred tax at that point.
| What the Branch Does With Its Profit | Part XIV Effect |
|---|---|
| Reinvests in Canadian property | Allowance reduces the base, tax deferred |
| Repatriates to head office | Taxed this year |
| Holds cash in Canada | Depends on whether it counts as qualifying property |
| Reduces its Canadian investment | Previously deferred amounts come back into the base |
The allowance is a running balance, not an annual reset. Cumulative amounts claimed in earlier years sit waiting, and a reduction in Canadian investment pulls them into income. A branch winding down often faces its largest branch tax bill in its final years, precisely when the owner expected the Canadian tax to be finishing.
The Treaty Does Two Things
The statutory rate is twenty-five per cent. For a US corporation the treaty generally cuts it to five and, separately, exempts the first five hundred thousand dollars of earnings that would otherwise be caught, cumulative over the life of the branch rather than annual.
Those two reliefs work together and the exemption is used up once. A branch that shelters four hundred thousand this year has a hundred thousand left for every future year combined, and once it is gone the five per cent applies to everything.
Track the cumulative exemption from the first year. It is the single figure most often lost when advisers change, and reconstructing it years later from incomplete records is difficult. It belongs in a permanent file alongside the Schedule 20 history.
Branch or Subsidiary
Because Part XIV exists to equalise the two, the tax comparison between a branch and a subsidiary is usually closer than people expect. What actually separates them is everything else.
| Consideration | Branch | Subsidiary |
|---|---|---|
| Early-year losses | Often usable against foreign income | Trapped in Canada |
| Liability exposure | Sits with the foreign company | Contained in the subsidiary |
| Second layer of Canadian tax | Part XIV branch tax | Dividend withholding |
| Administrative burden | No separate company to maintain | Separate filings and governance |
| Financial disclosure | Head office figures can be drawn in | Contained |
| Converting later | Possible, with tax consequences | Possible, with tax consequences |
The common pattern is a branch in the loss-making early years, when the losses are useful at home, followed by incorporation once the Canadian operation turns profitable. That conversion is itself a taxable event and needs planning rather than an assumption that it can be done at will.
Whether There Is a Branch at All
All of this assumes the foreign corporation is carrying on business in Canada and, under a treaty, has a permanent establishment here. Neither is automatic, and a company with Canadian customers, a warehouse or a visiting salesperson may or may not cross those lines.
Where there is no permanent establishment, a treaty generally prevents Canada from taxing the business profits at all, and the branch tax question never arises. That threshold is worth settling before computing anything on this page.
What This Calculator Does Not Cover
- Whether a permanent establishment exists, which decides whether Canada can tax the profits at all
- The detailed composition of qualifying Canadian property for the investment allowance
- Allocation of head office expenses to the Canadian branch, which is frequently contested
- Thin capitalisation and interest deductibility on funding from head office
- Converting a branch to a subsidiary and the tax consequences of doing so
- Foreign tax credit relief in the home country for the Canadian tax paid
If the branch has been running for several years without Schedule 20 being tracked properly, that is worth reconstructing now. Our non-resident corporation service covers the branch tax computation, the cumulative allowance, the treaty exemption history and the branch-versus-subsidiary decision.
