Here is a tax form that catches an alarming number of Canadian business owners off guard: a client sets up a US LLC to sell on Amazon or bill American clients, the LLC never sends a dollar back to Canada, and nobody files a T1134. Then the CRA notice arrives, and the penalty clock has been running at $25 a day. If you own even a small piece of a foreign corporation, the T1134 foreign affiliate return may already be on your to-do list, and the deadline works differently than every other tax filing you have.
What the T1134 foreign affiliate return actually is
Form T1134 is the CRA’s information return relating to controlled and not-controlled foreign affiliates. It is an information return, not a tax return: it does not calculate any tax owing. It exists so the CRA can see what Canadian residents own offshore, how those entities are structured, what they earn, and what moves between them and Canada.
The package has two parts: a summary and a separate supplement for every foreign affiliate you hold. Own shares in three foreign companies and you file the summary plus three supplements. The CRA treats each missing supplement as its own non-compliance, so the penalties multiply.
The 1% and 10% tests that decide whether you file
A foreign corporation is your foreign affiliate if two thresholds are met at any time during your tax year:
- Your equity percentage is at least 1%, and
- Your equity percentage, plus that of everyone related to you, is at least 10%.
Equity percentage is a defined term in the Income Tax Act, and it looks through indirect ownership, so holding shares through a Canadian holding company still counts. If you are one of four related people who each own 3% of a Delaware corporation, the combined 12% makes it a foreign affiliate for each of you.
A foreign affiliate is controlled when a Canadian taxpayer (alone, or together with up to four other Canadian shareholders and related persons) holds voting control, generally more than 50% of the voting shares. Controlled foreign affiliates face expanded disclosure and the FAPI rules, under which certain passive income is taxed in Canada every year even if nothing is paid out.
Who files? Canadian-resident individuals, corporations, and trusts, plus certain partnerships, that hold a foreign affiliate at any point in the year. It does not matter whether the affiliate earned income, paid dividends, or did anything at all. Filing is driven by ownership, not activity.
The US LLC trap
The most common way small owners fall into T1134 is the American LLC. The IRS may treat your single-member LLC as a disregarded entity, which is invisible for US tax purposes. Canada does not play along. The CRA treats a US LLC as a corporation, which means your LLC can be a foreign affiliate the moment your ownership crosses the 1% and 10% thresholds. File it like any other foreign affiliate, and do not let your American accountant’s shrug talk you out of it.
T1134 vs T1135: which form do you need?
These two forms get confused constantly. Here is the clean split:
- T1134 reports your ownership in a foreign affiliate: detailed information on ownership percentages, financial statements, surplus balances, transactions, and income.
- T1135, the Foreign Income Verification Statement, reports specified foreign property (bank accounts, foreign shares, bonds, non-Canadian real estate) when the total cost exceeds $100,000 at any time in the year.
Shares of a foreign corporation that qualify as your foreign affiliate are excluded from T1135. They go on T1134 instead, never both. If you hold foreign stocks under 10% through a Canadian brokerage alongside a 25% stake in a US operating company, you could legitimately need both forms.
The deadline and what being late costs
For 2021 and later tax years, the T1134 is due 10 months after the end of your tax year. For a December 31 year-end, that is October 31 of the following year, well after your corporate tax return was due. This is the deadline most people miss, because they assume foreign reporting rides along with the return. It does not.
The penalty for a late T1134 is $25 per day, minimum $100, maximum $2,500 per return. If the CRA considers the failure knowing or grossly negligent, the penalty jumps to $500 per month up to $12,000. After the CRA formally demands the return, knowing failures attract $1,000 per month up to $24,000. Failures more than 24 months old can draw an additional penalty of 5% of the cost of the shares or property. Interest runs on all of it.
Two practical warnings: first, if you are behind on multiple years, each year is a separate return and the penalties stack. Second, if you missed filings, the CRA’s Voluntary Disclosures Program is the usual relief route, and relief shrinks once the CRA contacts you first.
Dormant foreign affiliates: the one real exception
There is a narrow filing shortcut. A foreign affiliate is dormant or inactive for T1134 purposes if its gross receipts were under $100,000 in the year and its assets never had a fair market value above $1,000,000 in the year. If, on top of that, the total cost of your interests in all foreign affiliates at any time in the year was under $100,000, you can skip the supplement for that affiliate, though it still gets listed on the summary. Dormant does not mean exempt. Read the test carefully before you lean on it.
A practical T1134 checklist for owners
- Inventory your foreign holdings. List every non-Canadian corporation or LLC you own directly or indirectly, with ownership percentages.
- Run the 1% and 10% tests. Include related persons and look-through ownership before you conclude nothing applies.
- Mark October 31 on the calendar (for a December year-end), and treat it as a separate deadline from your corporate return.
- Separate T1134 from T1135. Foreign affiliate shares belong on T1134 only; other foreign property over $100,000 cost belongs on T1135.
- Do not skip years with no activity. Zero income and zero distributions never excuse the filing.
- If you are already late, act before the CRA writes. Voluntary correction beats a demand every time.
Foreign structures usually start for good business reasons: a US market entry, a joint venture, a holding structure. The reporting is the unglamorous part, and it is the part that costs money when ignored. A single missed T1134 with three affiliates and two late years can run to five figures in penalties before anyone calculates a cent of tax.
