What is the penalty for filing Form NR6 late?
There is no penalty attached to the undertaking itself, because it is not a return and there is no tax on it to be late with. The cost is different and often larger: filed after the year’s first rent payment, the undertaking does nothing for the year that has already begun, so withholding stays on the gross rent. The money is not lost, but it sits with the CRA until the elective return for that year recovers it, and the penalty exposure moves to that return instead.
My agent withheld on the gross rent all year — can I get it back?
Through the elective return for that year, yes. That return reports the rent and the deductible costs — mortgage interest, property tax, insurance, condo fees, repairs, agent commission — and calculates tax on what the property actually earned. The withholding already remitted on the gross rent is credited against it, and the difference is refunded. The records have to support every cost claimed, which is why the practical work on a late year is almost entirely document gathering rather than argument.
Is there a late filing penalty on the return I promised to file?
Yes, and that is where the real exposure sits once the undertaking is late. For the 2025 tax year the CRA late-filing penalty is 5% of the balance owing plus 1% of that balance for each full month the return is late, to a maximum of twelve months. Where the CRA issued a demand to file and charged a late-filing penalty in any of the three preceding tax years, it becomes 10% plus 2% for each full month, to a maximum of twenty months.
Does the late filing penalty double if it happens again?
No, and the description gets repeated so often that it is worth being precise. Two things have to be true for the higher rate: the CRA must have issued a demand to file, and it must have charged a late-filing penalty in one of the three preceding tax years. Filing late twice on its own does not do it. And the higher rate is not a doubling of the whole calculation — for the 2025 tax year the cap moves from twelve months to twenty, which is a different change from the rate doubling.
Does the penalty keep compounding until I pay?
The penalty does not compound. It is calculated on the balance owing and it stops at its cap. Interest is the part that compounds, daily, on the unpaid balance, and it keeps running after the penalty has reached its maximum. That matters for the order of work on a late rental year: paying down the balance once it is known limits the interest even while the return itself is still being assembled, whereas waiting to do everything at once only feeds the compounding part.
Do I need a new Form NR6 every year or does it carry over?
Each year stands on its own and needs its own undertaking, in place before that year’s first rent payment. Nothing rolls forward automatically, and an undertaking accepted for one year does not put the next year on a net basis. This is the most common way owners end up back on gross withholding after a clean first year — not a refusal, just a missed date. A dated reminder held by whoever acts as Canadian agent is usually all it takes.
Are US-listed ETFs US-situs property for a non-resident's estate?
Shares issued by a US company are generally US-situs for estate tax purposes, and a fund domiciled in the United States is a US company however global its holdings. A fund domiciled elsewhere that holds the same underlying stocks generally is not. That distinction — the domicile of the wrapper rather than the location of the investments — is why cross-border portfolios get restructured, and it should be confirmed against your own holdings before anything is sold. See US estate tax exposure for Canadians.
How do I claim a tax treaty benefit?
Three things usually have to line up: proof you are resident of the treaty country, a declaration to whoever is paying you so they withhold at the treaty rate rather than the statutory one, and the claim itself on the return of the country giving relief. Do it before the payment where a reduced rate is available — claimed afterwards it becomes a refund exercise instead, which takes far longer. See certificates of residency.
