What is the penalty for filing my Section 217 pension return late?
The late-filing penalty is charged by reference to a balance owing. For the 2025 tax year it is 5 per cent of the balance owing plus 1 per cent of that balance for each full month the return is late, to a maximum of 12 months. Where the CRA issued a demand to file and charged a late-filing penalty in any of the three preceding tax years, the charge is 10 per cent plus 2 per cent for each full month, to a maximum of 20 months. On this return the other question matters as much: the election carries a deadline of its own, separate from the ordinary filing date, and once it has gone the flat withholding on the pension payments is final.
My pension withholding exceeded the tax, is there still a penalty?
The late-filing charge applies to a balance owing, so where the graduated-rate result on the year is below the withholding already taken, there is no balance for the percentage to run on. The real exposure on a late pension year is the election deadline rather than the penalty. The election is what allows the year to be taxed at graduated rates instead of at the flat rate on each payment, and where it has lapsed, the excess withholding stops being recoverable through this route no matter how clearly the calculation favours you.
Can I still elect for an earlier pension year I never filed?
That is the question to settle first, because it decides whether filing achieves anything. The election has a deadline separate from the ordinary date for filing a return, so an unfiled year is not automatically an electable year. Where it is still open, the eligible income for that year can be computed at graduated rates and set against the withholding taken. Where it has closed, the flat withholding stands as the final position for that year. In a set of unfiled years the answer is frequently different for each one.
Does the penalty increase because I have filed late before?
Not because of repetition by itself. For the 2025 tax year the higher rate applies where the CRA issued a demand to file and charged a late-filing penalty in any of the three preceding tax years, and both parts of that have to be true. Where they are, the charge becomes 10 per cent of the balance owing plus 2 per cent for each full month, to a maximum of 20 months, in place of 5 per cent plus 1 per cent to a maximum of 12 months. The monthly cap moving from twelve to twenty is not itself a doubling of the period.
Will interest keep growing while I sort out old pension years?
Interest compounds daily on an unpaid balance, so yes, while a balance is outstanding it continues to grow. The late-filing penalty does not compound: once the balance owing for the year is established, the penalty on it is a fixed calculation. That difference sets the order of work on old pension files. Establish the year, settle whatever is genuinely owing to stop the compounding part, and the late-filing charge can then be dealt with as a known figure rather than one that changes while the correspondence goes back and forth.
Is it worth filing late if electing would not help me anyway?
Probably not through this route. The election is worth making only where the graduated-rate result beats the flat withholding already taken, and it is all-or-nothing across the eligible income for the year, so a recipient cannot elect for the favourable sources alone. If the calculation comes out against electing, filing the elective return late would create a balance owing and a late-filing charge on it where the withholding had already closed the year. The calculation is the decision, and it is worth running before any old year is filed.
Is double taxation illegal?
It is legal. Two countries can each have a valid claim on the same income — one because the income arose there, the other because you live there — and nothing prohibits both from exercising it. What exists instead is relief: tax treaties allocate the claim, and domestic law gives a credit for foreign tax paid. The relief is not automatic, though. It is claimed on a return, and unclaimed relief is simply lost. See how double taxation is relieved.
What does Form W-8BEN actually do?
It tells a US payer that you are not a US person and, where you are entitled, claims the treaty rate on the income they are about to pay you — so withholding comes off at the reduced rate rather than the statutory one. It goes to the payer or the broker, never to the IRS, and it expires, so a stale form is a common cause of over-withholding. Getting it in before payment is the difference between a lower rate and a refund claim. See Form W-8BEN.
