What happens if I file Form T1134 late?
The exposure on a late information return is charged by reference to the form and the delay, not to tax owing, so an affiliate that paid nothing out and produced no Canadian tax can still cost money to report late. Keep that separate from the late-filing penalty on the income tax return itself, which for the 2025 tax year is 5% of the unpaid balance plus 1% for each full month the return is late, to a maximum of twelve months. Before anything else, establish from the correspondence which charge is actually in play.
My foreign company had no income, does a late filing still matter?
Yes. The form is an information return about ownership and results, not a calculation of Canadian tax, so the absence of income removes neither the filing nor the consequence of filing late. In practice a dormant affiliate is the most likely one to go unreported for years, precisely because nothing happens to prompt anyone. The absence of activity does make the preparation lighter and the explanation easier to write, but it is not a reason to leave the years open or to assume that no charge can arise.
Do I file all the missing T1134 years at once?
Usually the filings go in together, but the order of work is not the order of filing. Establish the ownership position for the whole period first, because an affiliate that entered or left the group part way through changes which years are in scope and for which entity. Then deal with the surplus and classification questions, which have to be built forward from the earliest year rather than backwards from the latest. Filing the recent years first and the old ones later tends to produce inconsistent figures that then have to be amended.
Does the CRA charge more the second time a T1134 is late?
Not for repetition alone. On the income tax return the higher rates for the 2025 tax year, 10% of the unpaid balance plus 2% for each full month to a maximum of twenty months, apply only where the CRA issued a demand to file and charged a late-filing penalty in one of the three preceding tax years. Both limbs are needed, and twenty months is not a doubling of twelve. The practical step is to search the correspondence file for a demand letter before accepting that the higher figures are engaged.
Does interest run on top of a late filing penalty?
Interest and penalty behave differently, and the difference matters on an old file. The penalty does not compound. Interest does, daily, on whatever remains unpaid. So a long-standing balance grows on the interest side while the penalty stays where it was assessed. That points to a sequence: deal with the outstanding balance to stop the interest running, and pursue any argument about the penalty separately. Treating both as one number, and holding everything open until both can be settled together, is how a manageable amount becomes an unmanageable one.
Can the penalty be reduced if the foreign accounts arrived late?
Relief is discretionary, so the question is what the record shows rather than how reasonable the situation feels. Where overseas statements genuinely were not available, the useful material is dated: the requests made to the foreign accountants, the responses, the date the information finally arrived, and what was done in the interval. Build the chronology from documents and write the request around it. An explanation that depends on the reader accepting an account of events with nothing behind it is the weakest version of this submission.
Are foreign trusts taxable in Canada?
They can be. Canada's deemed-resident-trust rules can pull a non-resident trust into the Canadian tax system where there is a resident contributor or, in some cases, a resident beneficiary — taxing it as though it were resident here. Separate reporting applies to transfers or loans to a non-resident trust and to distributions and debts from one. The planning point is that contributing to an offshore trust from Canada rarely achieves what the brochure suggests. See non-resident trusts.
What is a permanent establishment, and how easily do we create one?
A taxable presence in another country under the treaty — typically a fixed place of business such as an office, branch, factory or workshop, or a dependent agent habitually concluding contracts on your behalf. Some treaties add a services test measured in days. Purely preparatory or auxiliary activity is excluded, but that carve-out is narrower than it sounds: one senior employee working from home in the other country, with authority, has been enough.
