Foreign Affiliate Reporting (T1134) for Canadian Corporations – Complete Compliance Guide 2026

By Bader A. Chowdry, CPA, CA, LPA | Insight Accounting CPA

If your Canadian corporation holds shares in foreign companies, understanding T1134 reporting obligations is critical. The Canada Revenue Agency (CRA) imposes strict filing requirements and significant penalties for non-compliance. In this comprehensive guide, we break down T1134 foreign affiliate reporting requirements, filing deadlines, and strategic considerations for multinational businesses operating in Mississauga, the GTA, and across Ontario.

What is the T1134 Information Return?

The T1134 Information Return is a mandatory disclosure form that Canadian taxpayers must file when they have ownership interests in foreign entities. The CRA uses T1134 forms to monitor offshore investments, track foreign income, and combat international tax evasion.

There are two primary versions of the T1134 form:

1. T1134 Summary Form – Overview of all foreign affiliates

2. T1134 Supplementary Forms – Detailed reporting for each foreign affiliate

These forms are complex, require granular financial data, and must be filed annually along with your corporate tax return (T2).

Who Must File a T1134?

Canadian corporations must file T1134 forms if they:

Own shares in a non-resident corporation (foreign affiliate)
Hold more than 10% ownership in a foreign corporation (direct or indirect)
Are part of a related group that collectively owns more than 10% of a foreign entity

Even if your foreign affiliate generates no income, you are still required to file if you meet the ownership thresholds.

Common Scenarios Requiring T1134 Filing

Ontario manufacturers with offshore production subsidiaries
GTA tech companies with US or European sales entities
Mississauga importers with distribution companies in Asia
Canadian holding companies with international portfolio investments
Private equity firms with cross-border fund structures

If your business operates internationally, you likely have T1134 filing obligations. At Insight Accounting CPA, we help businesses in Mississauga and the Greater Toronto Area navigate these complex international tax requirements.

T1134 Filing Deadlines

The T1134 forms must be filed within 10 months of your corporation’s fiscal year-end, which aligns with the T2 corporate tax return deadline.

| Form | Filing Deadline |

|——|—————-|

| T1134 Summary | 10 months after fiscal year-end |

| T1134 Supplementary (per affiliate) | 10 months after fiscal year-end |

| T2 Corporate Tax Return | 6 months after fiscal year-end |

Important: Even though the T1134 deadline is four months after the T2 deadline, you must plan ahead. Gathering foreign financial statements, exchange rate data, and ownership details takes time.

Late filing penalties are severe:

$100 per month per form (minimum $2,500, maximum $24,000 per form)
Penalties apply per foreign affiliate – if you have 5 foreign affiliates and file late, you could face $120,000+ in penalties

If you’re behind on T1134 filings, Insight Accounting CPA can help you navigate the CRA’s Voluntary Disclosures Program (VDP) to reduce or eliminate penalties.

T1134 Form Types: Summary vs Supplementary

T1134 Summary Form

The summary form provides a high-level overview of all your foreign affiliates. It includes:

List of all foreign entities with ownership interests
Country of residence for each affiliate
Type of foreign affiliate (controlled foreign affiliate, non-controlled, etc.)
Total assets and income of each affiliate

T1134 Supplementary Forms

Each foreign affiliate requires a separate supplementary form that includes:

Detailed financial statements (balance sheet, income statement)
Ownership structure and shareholding percentages
Transactions between the Canadian corporation and the foreign affiliate (intercompany loans, management fees, royalties)
Foreign accrual property income (FAPI) calculations
Surplus balances (exempt surplus, taxable surplus, pre-acquisition surplus)

For multinational corporations in Ontario with complex foreign structures, preparing T1134 forms can be a multi-week process requiring specialized international tax expertise.

Understanding Foreign Affiliate Categories

Not all foreign affiliates are treated equally under Canadian tax law. The classification determines your reporting obligations and tax exposure.

1. Controlled Foreign Affiliate (CFA)

A foreign affiliate is “controlled” if the Canadian corporation (alone or with related parties) owns more than 50% of the voting shares.

Key tax implications:

Subject to FAPI rules (passive income taxed in Canada annually)
More extensive reporting requirements
Potential application of transfer pricing rules

2. Non-Controlled Foreign Affiliate

Ownership between 10% and 50% without control.

Key tax implications:

T1134 reporting still required
FAPI may still apply in certain situations
Dividend income from non-controlled affiliates receives preferential tax treatment

3. Foreign Affiliates in Treaty Countries

Foreign affiliates located in countries with tax treaties with Canada (such as the US, UK, Germany) receive special treatment:

Exempt surplus dividends may be received tax-free in Canada
Reduced withholding tax rates on dividends and interest
Enhanced dispute resolution mechanisms

If you’re expanding into treaty jurisdictions like the United States or Europe, proper T1134 compliance is essential to preserve treaty benefits. Our team at Insight Accounting CPA in Mississauga specializes in cross-border tax planning for GTA businesses.

Foreign Accrual Property Income (FAPI)

One of the most complex aspects of foreign affiliate reporting is FAPI – Foreign Accrual Property Income.

FAPI refers to passive income earned by a controlled foreign affiliate, including:

Interest income
Rental income (non-active business)
Royalty and licensing fees
Investment income (dividends, capital gains)

Even if the foreign affiliate does not remit dividends to Canada, FAPI is immediately taxable in Canada in the year it is earned. This prevents Canadian corporations from indefinitely deferring tax on passive offshore income.

FAPI Exemptions

There are important exemptions to FAPI, including:

Active business income earned by foreign affiliates
Income from designated treaty countries under certain conditions
Income subject to adequate foreign tax (more than 90% of Canadian rate)

Calculating FAPI requires detailed knowledge of both Canadian tax law and the tax system of the foreign jurisdiction. At Insight Accounting CPA, we work with multinational businesses in Ontario to minimize FAPI exposure while maintaining CRA compliance.

Common T1134 Filing Mistakes to Avoid

1. Missing the 10-Month Deadline

This is the most common and costly mistake. Even if your T2 is filed on time, late T1134 forms trigger automatic penalties.

Solution: Start T1134 preparation at the same time as your corporate year-end financial statements (at least 3-4 months before the deadline).

2. Incomplete Financial Data

The CRA requires complete foreign financial statements converted to Canadian dollars. Many businesses underestimate the effort required to collect and convert this data.

Solution: Establish annual reporting procedures with your foreign subsidiaries. Request foreign financial statements in English and in the local currency, with clear documentation of intercompany transactions.

3. Incorrect Exchange Rates

All foreign currency amounts must be converted using the Bank of Canada average annual exchange rate for the taxation year.

Solution: Use the official Bank of Canada rates and document your conversion calculations. The CRA scrutinizes foreign currency conversions during audits.

4. Failure to Report Intercompany Transactions

Loans, management fees, royalties, and other transactions between your Canadian corporation and foreign affiliates must be disclosed on the T1134.

Solution: Maintain a detailed intercompany transaction log throughout the year. This also supports your transfer pricing documentation requirements.

5. Overlooking Indirect Ownership

Ownership includes both direct and indirect shareholding. If your Canadian corporation owns 60% of a US holding company, which in turn owns 100% of a Mexican subsidiary, you have an indirect ownership interest in the Mexican company and must file T1134 for both entities.

Solution: Map out your complete corporate structure at the beginning of each fiscal year. Engage a CPA experienced in international tax to review your structure.

T1134 vs T1135: What’s the Difference?

Many business owners confuse the T1134 (Foreign Affiliate Reporting) with the T1135 (Foreign Income Verification Statement).

| Feature | T1134 | T1135 |

|———|——-|——-|

| Who Files | Corporations with foreign affiliates | Individuals and corporations with foreign property |

| Threshold | 10%+ ownership in foreign entity | $100,000+ in foreign property |

| Filing Deadline | 10 months after year-end | April 30 (individuals), T2 deadline (corporations) |

| Penalties | $100/month per form (max $24,000) | $25/day (max $2,500) + gross negligence penalties |

Most multinational corporations must file both T1134 and T1135. At Insight Accounting CPA, we prepare comprehensive foreign reporting packages to ensure full compliance with both forms. Learn more about T1135 foreign property reporting here.

Strategic Tax Planning with Foreign Affiliates

Beyond compliance, foreign affiliate structures offer significant tax planning opportunities for Canadian multinationals.

1. Dividend Repatriation Planning

Dividends from foreign affiliates can be received tax-free in Canada if they are paid from exempt surplus. Strategic planning around dividend timing and surplus classifications can save significant tax.

2. Foreign Tax Credit Optimization

Canadian corporations can claim foreign tax credits for taxes paid by foreign affiliates on certain types of income. Proper planning ensures maximum credit utilization.

3. Hybrid Entity Structures

Certain foreign entities are treated differently under Canadian vs foreign tax law. Strategic use of hybrid structures can result in double non-taxation (legally avoiding tax in both jurisdictions).

Important: Aggressive hybrid structures are under increasing CRA scrutiny. Always ensure your structures have legitimate business purposes beyond tax savings.

4. Transfer Pricing Compliance

Intercompany transactions between your Canadian corporation and foreign affiliates must be priced at arm’s length. Transfer pricing documentation is mandatory for many transactions and supports your T1134 filings.

For businesses expanding internationally, integrating T1134 compliance with broader tax planning strategies is essential. Our team at Insight Accounting CPA in Mississauga works with GTA businesses to design compliant, tax-efficient international structures.

CRA Audits of Foreign Affiliate Reporting

Foreign affiliate reporting is a high-risk audit area for the CRA. The Aggressive Tax Planning and International Audit teams actively review T1134 filings for:

Late or missing filings
Incomplete financial data
Questionable intercompany transactions
FAPI miscalculations
Transfer pricing issues

What Triggers a T1134 Audit?

Common audit triggers include:

First-time foreign affiliate filings (no prior history)
Large fluctuations in foreign affiliate income or assets
Related party transactions without transfer pricing documentation
Foreign affiliates in tax haven jurisdictions
Inconsistencies between T1134 and T1135 filings

If you receive a T1134 audit notice from the CRA, do not handle it alone. International tax audits are complex and require specialized representation. At Insight Accounting CPA, we provide CRA audit defense services for businesses throughout Ontario.

Frequently Asked Questions (FAQ)

1. What happens if I don’t file a T1134?

Failure to file T1134 forms results in penalties of $100 per month per form, with a minimum penalty of $2,500 and a maximum of $24,000 per form. If you have multiple foreign affiliates, penalties multiply. The CRA can also reassess your tax return and deny foreign tax credits or exempt surplus treatment.

2. Can I file a late T1134 without penalties?

You may be able to file a late T1134 under the CRA’s Voluntary Disclosures Program (VDP) and reduce or eliminate penalties. VDP applications require full disclosure of all foreign affiliates and payment of any taxes owing. Our team at Insight Accounting CPA in Mississauga can prepare VDP applications and negotiate with the CRA on your behalf.

3. Do I need a T1134 if my foreign affiliate has no income?

Yes. T1134 filing requirements are based on ownership, not income. Even dormant foreign affiliates require annual T1134 filings. If you’re unsure whether a foreign entity qualifies as a foreign affiliate, consult with a CPA experienced in international tax.

4. How do I calculate FAPI for my controlled foreign affiliate?

FAPI calculations require you to separate active business income from passive investment income, apply foreign tax adjustments, and track surplus accounts (exempt, taxable, pre-acquisition). FAPI rules are among the most complex in Canadian tax law. We recommend working with a specialist CPA to ensure accurate calculations.

5. Can I claim foreign tax credits for taxes paid by my foreign affiliate?

In certain cases, yes. The foreign tax credit rules differ depending on whether the income is FAPI, dividend income from exempt surplus, or other foreign-source income. Strategic planning around foreign tax credit claims requires integration with your overall corporate tax planning.

6. What if my foreign affiliate is in a tax haven?

Foreign affiliates in designated “tax haven” jurisdictions face heightened CRA scrutiny. You must demonstrate that the foreign affiliate has legitimate business purposes (substance, employees, operations) beyond tax avoidance. Transfer pricing documentation and detailed T1134 filings are essential. Our team at Insight Accounting CPA can help you document the commercial rationale for offshore structures.

Take Action: Ensure Your T1134 Compliance Today

If you’re a Canadian corporation with foreign affiliates, T1134 compliance is not optional. The penalties for late or incorrect filings can exceed the cost of professional preparation many times over.
