The T1134 is widely regarded as one of the most confusing forms in Canadian tax practice. It was introduced in 1997 as a relatively straightforward disclosure tool. A significant overhaul in 2020 transformed the Summary from two pages to five and the Supplement from four pages to eight. The result is a form that references Income Tax Act provisions most practitioners never encounter in domestic practice, with limited guidance and considerable potential for error.
This guide answers the foundational questions: who has to file, which entities require a supplement, what the key definitions mean, and where the most common errors occur. The FAPI computation methodology, surplus pool calculations, and upstream loan mechanics are covered in the seminar program below.
What Is the T1134 and Why Is It Part of the Foreign Reporting Package
The T1134 is one of four forms in Canada’s foreign reporting package, alongside T1135 (Foreign Income Verification Statement), T1141, and T1142. Each form addresses a different type of foreign exposure. The T1134 is specifically for foreign affiliates and controlled foreign affiliates: non-resident corporations in which a Canadian resident has a meaningful ownership interest.
A critical and persistent error in practice is filing a T1135 for an entity that should be reported on a T1134. If the non-resident entity qualifies as a foreign affiliate, it belongs on a T1134 supplement, not on the T1135. These are not interchangeable. Filing the wrong form may mean the CRA never receives the disclosure it is entitled to, and the T1134 penalties may still apply.
The rule: If the non-resident entity is a foreign affiliate, file T1134. Do not file T1135 instead. Many practitioners who handle this situation infrequently default to the T1135 by habit. This is incorrect.
The form has grown substantially since its 1997 introduction. The 2020 overhaul added new disclosure fields tied to legislative changes designed to curtail offshore structures, and further amendments introduced in 2024 may add additional complexity when passed.
Who Must File: The Reporting Entity
Any Canadian resident taxpayer who owns a foreign affiliate or controlled foreign affiliate at any time during the taxation year must file a T1134. This includes corporations, individuals, and trusts. The form is not limited to corporations.
Who Is In and Who Is Out
Tax-exempt entities are not required to file. First-time immigrant individuals are exempt for their first year of Canadian residency; returning residents are not exempt. Deemed resident trusts are considered Canadian residents for T1134 purposes and must file.
Certain partnerships must file in place of their partners: specifically, where 10% or more of the partnership income or loss belongs to Canadian resident members and a non-resident corporation would be a foreign affiliate of the partnership if the partnership were a person resident in Canada.
The “At Any Time” Standard
Ownership at any point during the taxation year triggers the filing obligation. A foreign entity that was acquired and then sold during the year still requires a supplement. A dormant foreign entity with no revenue, no assets beyond initial subscription proceeds, and no activity still requires a supplement if it qualifies as an FA or CFA.
What to Attach
The primary information sources are the financial statements and foreign tax return for each foreign affiliate. These can be attached as issued in their original language. Translation is not required. If no financial statements have been prepared, note this in Part IV of the form and attach once available.
The Due Date and What Happens If You Miss It
The T1134 is due 10 months after the year-end of the Canadian reporting entity. For a corporation or individual with a December 31 year-end, that means October 31 of the following year.
Penalties apply to late filing. If information is incomplete at the filing deadline, the correct approach is to file on time with whatever is available, note the missing information in Part IV, and provide the remaining details as soon as they are obtained. Filing late, even by a day, is not the recommended workaround for incomplete information.
One timing complication arises with different year-ends: the T1134 reports on foreign affiliates whose fiscal year-end falls within the Canadian reporting entity’s taxation year. If the foreign affiliate has an October 31 year-end and the Canadian parent has a December 31 year-end, the foreign affiliate’s October 31 year falls within the parent’s December 31 year. That foreign affiliate is reported on the parent’s T1134 for that calendar year. Year-end mismatches between the reporting entity and its FAs add a layer of complexity to the timing analysis.
Due date examples:
Dec 31 year-end → T1134 due October 31
Mar 31 year-end → T1134 due January 31
Jun 30 year-end → T1134 due April 30
Foreign Affiliate vs. Controlled Foreign Affiliate: The Distinction That Determines Your Workload
Every entity on a T1134 is either a foreign affiliate or a controlled foreign affiliate. That classification determines how complex the supplement is. Understanding the difference is the starting point for every T1134 engagement.
Foreign Affiliate (FA)
A non-resident corporation is a foreign affiliate of a Canadian taxpayer when two conditions are met: the taxpayer itself holds at least 1% of any share class of the corporation, and the taxpayer together with related parties holds at least 10% in total across all classes. These percentages are called equity percentages and are discussed in the next section.
For an FA that is not a CFA, the T1134 supplement is relatively straightforward. No foreign accrual property income analysis is required. Income is not imputed to the Canadian shareholder annually. The reporting is largely descriptive: ownership structure, financial information, gross revenue.
Controlled Foreign Affiliate (CFA)
A CFA is a subset of an FA. The CFA designation applies when the Canadian taxpayer either directly controls the foreign affiliate, or would control it if the taxpayer’s own shares were combined with shares held by up to four related or affiliated persons. The extended control test is designed to capture situations where multiple related Canadian shareholders together control a foreign entity, even if no single shareholder does.
One important feature: non-arm’s length non-residents can trigger CFA status for a Canadian shareholder. There is no residency requirement for the persons in the extended group to be Canadian. If a non-arm’s length non-resident holds shares that, combined with the Canadian’s shares, would constitute control, the foreign entity is a CFA.
| Form Element | FA Only | CFA |
|---|---|---|
| Basic ownership information | Required | Required |
| Financial statements attached | Required | Required |
| Gross revenue disclosure | Required | Required |
| FAPI calculation | Not required | Required |
| Surplus account tracking | Not required | Required |
| Upstream loan disclosure | Not required | Required |
| ACB adjustment disclosures | Not required | Required |
Equity Percentage: How Ownership Is Measured
The equity percentage is the metric used to determine whether an entity is an FA, and by how much. It is not the same as voting control. The distinction matters frequently in practice.
Direct Equity Percentage
For a directly held foreign entity with a single share class, the equity percentage equals the ownership percentage of that class. If there are multiple share classes, take the highest percentage ownership across all classes. It is not a blended or average figure. If a Canadian taxpayer owns 5% of common shares and 60% of preferred shares, the equity percentage is 60%.
Indirect Equity Percentage
For multi-tier structures, the equity percentage is determined by multiplying through the chain. If a Canadian corporation owns 80% of an intermediate foreign company, and that intermediate company owns 25% of a lower-tier foreign company, the equity percentage in the lower-tier entity is 80% multiplied by 25%, equalling 20%. This calculation is done for each tier of ownership between the reporting entity and the FA in question.
Equity Percentage Does Not Equal Control
A common source of confusion: a high equity percentage does not mean an entity is a CFA. Control for CFA purposes requires voting rights that allow the election of a majority of the board of directors. Non-voting preferred shares can produce a high equity percentage without producing control. An entity can be an FA with a 70% equity percentage and still not be a CFA if the shares owned carry no voting rights.
U.S. LLCs and Entities Without Shares
Some foreign entities treated as corporations for Canadian tax purposes do not have conventional share classes. U.S. LLCs are a common example. In these cases, the Act requires the entitlement rights of the entity to be identified and grouped into deemed share classes. The equity percentage is then calculated based on each owner’s proportionate interest in each deemed class.
This is one of the most common error points on T1134 filings. A U.S. LLC is treated as a corporation for Canadian tax purposes, not a partnership. Applying the U.S. partnership treatment and filing a T1135 instead of a T1134 is incorrect.
FAPI: Why the CFA Designation Changes the Complexity Entirely
When a foreign affiliate is a CFA, the reporting entity must analyze whether any of the CFA’s income is foreign accrual property income (FAPI). FAPI is broadly defined as passive income earned by a CFA, and it is imputed to the Canadian resident shareholder for the year the CFA earns it, whether or not any distribution is made.
What Generally Qualifies as FAPI
FAPI includes income from an investment business (interest, dividends, rents, royalties, and similar property income), income from businesses other than active businesses, and certain categories of income deemed passive by specific provisions in the Act. Common examples include rental income where there are not more than five full-time employees, income from services performed by the Canadian shareholder personally, and most capital gains unless they arise from excluded property.
An important nuance: a loss in the foreign country does not automatically mean there is no FAPI. FAPI is computed under Canadian tax rules, not the rules of the foreign jurisdiction. The foreign tax return and financial statements are starting points, not the final answer.
Active Business Income: Not FAPI
Most CFAs set up to conduct genuine business operations will have active business income. Active business income is not FAPI and is not imputed to the Canadian shareholder. Canadian tax is deferred until funds are distributed. When distributed to a Canadian corporation as a dividend from exempt surplus, the dividend is received tax-free. This is the standard structure for most U.S. subsidiaries earning active business income.
The Surplus Pools
Foreign affiliates track retained earnings in four surplus pools: exempt surplus (active income from treaty countries, paid tax-free when distributed), taxable surplus (passive income and income from non-treaty countries, taxable on distribution with foreign tax relief), hybrid surplus (certain capital gains), and pre-acquisition surplus (the default category, which reduces ACB and can trigger a capital gain if the ACB goes negative). Tracking these pools requires ongoing record-keeping from the time of acquisition.
