Do I file Regulation 105 even if no tax is owed?
Certificate or waiver obligations of this kind are generally required on the facts rather than on the tax result, so a nil position does not remove one. Non-resident service providers working in Canada, and the Canadian payers who would otherwise withhold on their gross fees.
What happens if I have missed Regulation 105 for several years?
Missed years are dealt with as a package rather than one at a time, because the route chosen for the first year affects the relief available for the rest. We map the years and the obligations before anything is filed.
Is Regulation 105 the same as the other reports I already file?
No. The waiver application that reduces or removes withholding on fees paid to a non-resident for services rendered in Canada. Satisfying a different obligation, even one covering the same accounts or entity, does nothing for this one.
Why is our Canadian client holding back tax from our invoice?
Because a Canadian payer is required to withhold on fees paid to a non-resident for services performed in Canada, and the obligation sits on the payer rather than on you. The point that surprises most suppliers is that the withholding is calculated on the gross fee, not on the profit. No allowance is made for the wages, travel, subcontractors or equipment that produced the work. On an engagement with real costs behind it, the amount held back routinely exceeds the Canadian tax that will eventually be due. A Regulation 105 waiver exists to correct that in advance.
Can I apply for a Regulation 105 waiver after I have been paid?
No. A waiver reduces or removes an obligation to withhold on a payment that has not yet been made, so once the payment has gone through with tax deducted there is nothing left to waive. What remains is recovery, which means filing a Canadian return for the year, setting the real income and expenses of the engagement against the amount withheld, and claiming the difference back. That route does work. It is simply slower and more expensive than applying in time, and it leaves your money with the CRA in the meantime.
How far ahead should a Regulation 105 waiver be applied for?
Work backwards from the first payment rather than from the first day on site. The application has to be with the CRA and decided before the payer releases the fee, so the date that governs your timetable is the earliest invoice date in the contract, including any deposit or mobilisation payment. Lead time is the binding constraint on these applications far more often than the merits are. Check the CRA's current guidance on processing when you plan the engagement, and arrange the waiver while the contract is being negotiated rather than after it is signed.
What is the difference between a treaty waiver and an expense-based waiver?
They are two different arguments for the same relief. The treaty route says the fee should not be taxed in Canada at all, given what the treaty says about services of that kind performed by a resident of your country. The income-and-expense route accepts that there is Canadian tax to come, but shows from budgeted revenue and costs that withholding on the gross fee would take far more than the eventual liability. Which one is available depends on where you are resident and how the engagement is structured, and the evidence each needs is quite different.
If the waiver is granted, do I still file a Canadian return?
Generally yes, and treating a granted waiver as the end of the matter is a common and avoidable mistake. The waiver addresses the withholding, meaning how much is taken off as the payment is made. It is not a determination that no Canadian filing obligation arises from performing services here. The return is where the actual income and expenses of the engagement are reported and the final position settled. Plan for both when you price the work, so the compliance cost sits in the budget rather than arriving as a surprise after the project closes.
Is the Canadian payer liable if they do not withhold?
Yes, and that is why payers are so reluctant to release a gross payment on assurances alone. The obligation to deduct is the payer's, so a Canadian business that pays a non-resident supplier in full, without holding either a waiver or a sound basis for not withholding, carries the exposure itself rather than the supplier. From the supplier's side this is worth understanding rather than resenting. The payer is not being difficult. Giving them a granted waiver, or a clear written position, is what allows them to pay in full.
How is a Regulation 105 waiver different from a Regulation 102 one?
Regulation 105 is about fees for services, not employment income: a payer in Canada withholds from amounts paid to a non-resident for services rendered in Canada, on the gross payment rather than on any profit. That is why the waiver matters so much here — withholding on turnover can exceed the tax actually owed on a thin margin. The waiver application asks the CRA to accept, in advance, that a treaty or the economics of the contract justify reducing it. Regulation 102 covers the same idea for employees.
How do I report the sale of a foreign property?
On your residence-country return, as a disposition, with proceeds and cost base converted at the rates for their own dates. Separately, the country where the property sits may require its own return and may hold back tax at closing until a clearance or certificate is issued — Canada does this for a non-resident vendor, and the United States withholds on a foreign seller of US real property. Those steps have their own deadlines, often before closing. See clearance certificates on a property sale.
