How much is the penalty if our T2 is filed late?
For the 2025 tax year the late-filing penalty is 5 per cent of the balance owing when the return was due, plus 1 per cent of that balance for each full month the return is late, to a maximum of twelve months. Because it is measured on the balance owing, the size of the penalty follows the tax rather than the delay on its own. Interest is a separate charge and works differently: it compounds daily on the unpaid balance, while the penalty itself does not compound. The two are often quoted together as a single figure on an assessment, which is why a corporation that wants to know what it is actually paying should have them separated first.
Does the late filing penalty double if we were late before?
No, and the popular version of this is wrong in two ways. For the 2025 tax year a higher rate can apply — 10 per cent of the balance owing plus 2 per cent of that balance for each full month, to a maximum of twenty months — but it is not triggered by lateness on its own. It applies where the CRA issued a demand to file the return and charged a late-filing penalty in any of the three preceding tax years. Both limbs are needed. And the higher figures are not a doubling of the ordinary ones: the ceiling moves from twelve months to twenty, which is a different shape of exposure rather than twice the same one.
What happens if the T2 is late but the corporation owes nothing?
The late-filing penalty is calculated as a percentage of the balance owing, so where there is no balance the percentage produces nothing. That is a narrower comfort than it sounds. The return still has to be filed, the schedules that travel with it still have to be completed, and the foreign reporting attached to a cross-border group carries consequences charged by reference to the form and the delay rather than to the tax. A nil year is also the year most often left unfiled, which is how a company ends up with a run of missing returns and no simple way to show what happened in any of them.
Does the T2 late filing penalty grow every month until we file?
It grows, but not indefinitely and not by compounding. For the 2025 tax year the monthly element runs at 1 per cent of the balance owing for each full month the return is late, to a maximum of twelve months, on top of the initial 5 per cent. Once that ceiling is reached the penalty stops increasing. Interest behaves differently and is the part that keeps moving: it compounds daily on the unpaid balance. So a corporation that has passed the penalty ceiling is still accumulating cost, and that cost is interest. Filing stops the penalty clock; paying is what stops the interest.
How many years of overdue corporation returns should we file at once?
Usually all of them, and as one piece of work rather than year by year. In a cross-border group the schedules are read together, so a year filed on its own tends to describe a structure that the next year contradicts. Preparing the outstanding years together lets the foreign holdings, the payments to non-residents and any treaty position be stated consistently across the whole run, which is what they will be compared against. It is also cheaper done once. We establish which years are outstanding, rebuild each from the corporate records, and file them as a set with a short covering explanation of what happened.
Our schedules were wrong rather than missing — does that count as late?
Those are two different problems. A return filed on time with incorrect schedules is not a late return, and the late-filing penalty is not the mechanism that deals with it; the correction is made by amending the return so the schedules describe the facts properly. A return filed without the schedules it needed is a weaker position, because an incomplete return invites the question of whether it was really filed. In a cross-border group the risk in both cases is the same: the schedules are read against each other and against what the group filed elsewhere, so an error left standing gets louder each year rather than quieter.
Do I need to report a foreign business I own?
Almost certainly, and on more than one form. Canada requires reporting of foreign affiliates on the T1134; the United States has a family of returns keyed to the entity type and your level of control, and several carry penalties that apply whether or not any tax is owed. These are information returns, so the obligation follows the ownership rather than the profit. See T1134.
What is OECD Pillar Two?
A global minimum effective tax for large multinational groups, delivered through top-up taxes rather than a single global rate. Where a group's effective rate in a jurisdiction falls below the agreed minimum, the shortfall is collected — by the parent jurisdiction under the income inclusion rule, by the source jurisdiction under a domestic top-up, or as a backstop by other jurisdictions. Canada has enacted implementing legislation. The compliance burden is data, long before it is tax. See BEPS and Pillar Two.
