The application to refund Canadian non-resident withholding tax that exceeded what the treaty or the Act required. The exposure on this kind of filing is charged by reference to the form and the delay rather than to the tax, which is why an unfiled year with no tax can still be expensive.
The application to refund Canadian non-resident withholding tax that exceeded what the treaty or the Act required.
Recovering over-withheld tax runs on its own time limit, and the claim needs the slip, the treaty basis and residency evidence together. It is far cheaper to fix the certificate before the payment than to reclaim afterwards.
The full treatment — who it binds, the deadline, the penalty and the fixed fee — is on NR7-R — refund of Part XIII tax. Whatever you have is enough to start the conversation, including nothing but the dates.

A non-resident arrived with several years of Canadian slips showing tax withheld at the statutory rate, having assumed the whole lot could be reclaimed together. Because each remittance runs on its own limit, the work began with dating every payment and testing each year against it, rather than with treaty analysis. Some years were still open and some were not. The engagement produced claims for the open years with slip and residency evidence attached, and a written note of the years that had closed and why.
Read how this one runsA late Canadian filing brought to light that payments to the same taxpayer had also been over-withheld at source in earlier years. The two problems settle on different timetables, so they were run in parallel rather than folded together: the return was completed and the balance quantified so interest stopped growing on it, while the refund claims were prepared separately against their own limit. The engagement produced a filed return with its exposure set out in writing and refund claims lodged for the years still open.
Read how this one runsA non-resident holding unclaimed withholding also received a demand from the CRA for an unfiled year, and had been told the penalty would be at the higher rate. The work was to test both conditions rather than accept that. We reviewed the account history for the three preceding tax years to see whether a late-filing penalty had actually been charged in any of them. It had not. The engagement produced a written exposure calculation at the ordinary rate and a filing sequence for the outstanding year.
Read how this one runsA claim could not be filed because the slip covering the remittance had never reached the recipient and the payer’s copy could not be located. With the year approaching its limit, the work was to reconstruct the remittance from what did exist: bank credits for the net payment, the payer’s ledger entries, and correspondence stating the rate applied. The payer then issued a replacement slip. The engagement produced the slip, a reconciliation supporting it, and a claim filed while the year was still open.
Read how this one runsA recipient abroad had been over-withheld on Canadian payments across a run of years and came to us after the earliest of them had passed its limit. Saying so plainly was part of the work, because the alternative was a fee spent on a claim that could not succeed. We documented the closed year and the reason, then concentrated on the years still open, assembling a slip, the treaty article and residency evidence for each. The engagement produced filed claims for the open years and a written position on the closed one.
Read how this one runsA taxpayer resident abroad had reclaimed over-withheld Canadian tax twice, each time late and each time with a fresh residency certificate obtained after the event. Rather than prepare a third claim in isolation, the work looked at the payment stream. We identified the treaty article that applied, prepared the declaration of eligibility for the payer to hold before the next payment run, and filed the outstanding claim. The engagement produced one final claim and a withholding basis that removed the need to repeat the exercise.
Read how this one runsWhere the income was on the return and only the account report was missed, a narrow route allows late filing with a reason attached. It is open only while no income is unreported and no examination has begun, which is why it is checked first.
Read how this one runsOwning a company abroad triggers an information return separate from the corporate return, with its own penalty. The work is the surplus and income computations behind it, which also determine how a future dividend is taxed on the way home.

Strategy and compliance for income, assets and families spread across borders.
Software revenue crosses borders by default — sourcing rules, withholding on licence-like payments and IP location decide the effective rate.
Software revenue is rarely taxed where the team sits. Licence, subscription and service income are characterised differently by each side, and the answer decides withholding at source, treaty relief and whether a foreign customer creates a taxable presence at all — questions that are cheap to settle before the contract and expensive afterwards.
No, and the reason is structural. A refund claim is a request for money the CRA is holding, not a return reporting tax you owe, so there is no balance for a late-filing penalty to be calculated on. The cost of being late is the claim itself: recovering over-withheld Part XIII tax runs on its own time limit, and once the year is closed the money stays where it is. Nothing is charged, and nothing comes back either.
It depends on the year the tax was remitted rather than the year you found the slip. Each remittance has its own clock, which is why a bundle of old slips usually divides into years that can still be claimed and years that cannot. The first piece of work is dating each one and checking it against the limit, before any time goes into assembling treaty and residency evidence for a year that is already closed.
Then two different regimes apply and only one of them carries a penalty. The refund claim has no penalty but a time limit. The return does have one: 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. That is calculated on tax owing, so a return with no balance is not where the exposure lies.
Not in the way it is usually described. Two conditions have to be met together: the CRA must have issued a demand to file, and it must have charged a late-filing penalty in any of the three preceding tax years. Having filed late before, by itself, is not the trigger. Where both are met, for the 2025 tax year the penalty becomes 10% of the balance owing plus 2% for each full month, to a maximum of twenty months rather than twelve.
The penalty does not compound and it stops at its cap. Interest compounds daily on the unpaid balance and carries on after that. On a file where over-withheld tax is being reclaimed at the same time as a balance is owing, that shapes the order of work: the interest-bearing balance is dealt with first, and the refund claim runs alongside rather than being treated as the thing that pays it, because the two are settled on separate timetables.
Yes, and it is the cheaper answer. A declaration of treaty eligibility in the payer’s hands before they pay applies the treaty rate at source, so there is nothing to reclaim and no time limit to watch. Reclaiming afterwards means one claim per remittance, each with its own slip and residency evidence, for money you were entitled to keep in the first place. Where payments recur, fixing the certificate is the last piece of work rather than the first of many.
Usually in at least one country, and which one depends on the treaty article covering pensions — some give the taxing right to the country paying it, others to where you live, and several treat government service pensions differently again. Withholding at source is common and often reducible by treaty, with an elective return recovering an over-deduction. See the pensions article.
Part XIII is the Canadian charge on certain amounts paid to non-residents — rent, dividends, interest, royalties, pensions and similar passive income. The payer withholds and remits it, and it is a flat charge on the gross payment rather than on profit, which is why a non-resident landlord can be withheld on far more than the net rental result. Treaties reduce the rate and elective returns recover the excess. See the section 216 return.
