Anonymised, illustrative composite. A seller who had quietly become a non-resident put $65,000 of the sale proceeds under a federal withholding rule most agents only meet once.
At a glance
A Vancouver-area house sold for $780,000. The listing agent learned partway through the deal that the seller had relocated abroad two years earlier and was not a Canadian resident for tax purposes — a fact that changes who is responsible for a chunk of tax on the sale, and when.
The Income Tax Act puts the obligation on the buyer, not the seller. Under section 116, where a non-resident disposes of Canadian real property, the purchaser must withhold and remit 25% of the amount by which the purchase price exceeds the seller's “certificate limit” — broadly, the seller's cost base as fixed by a CRA clearance certificate — unless that certificate has already been issued before closing. As treadstonelaw.ca's own seller-closing-costs page notes, “that certificate takes months, not weeks” — a timing fact no statute page states, and one that shaped everything else on this file.
The seller's certificate limit, once the CRA process was underway, was fixed at $520,000. The excess over that on the $780,000 sale price is $260,000, and 25% of that is $65,000 — the amount that had to be either withheld from the seller's proceeds or, for certain property types under s. 116(5.2), withheld at a 50% rate instead. This sale did not fall into that higher-rate category.
There are two routes. Pre-disposition, the non-resident can notify the Minister before closing with the property details and estimated proceeds; on payment of the 25% tax or acceptable security, the Minister issues a certificate fixing the certificate limit in advance. Post-disposition, the non-resident must notify the Minister within 10 days after the sale if no matching pre-disposition certificate already issued. Without a certificate at all, the purchaser is personally on the hook: liable to remit 25% of the excess to the Receiver General within 30 days after the end of the month the property was acquired, with only a right to recover that amount back from the non-resident seller afterward. A clearance certificate can also be refused outright on unrelated grounds: under s. 116(8), the Minister may decline to issue one where the non-resident has not filed the returns or paid the amounts required under the Underused Housing Tax Act for the property — a second, separate compliance file worth checking on any non-resident-seller closing.
This is a different mechanism from a foreign-buyer purchase tax. British Columbia's own Additional Property Transfer Tax, for example, charges 20% of the fair market value of a foreign purchaser's share, in specific regions including Metro Vancouver, while Ontario runs a comparable 25% Non-Resident Speculation Tax on certain foreign buyers province-wide since October 25, 2022. Both of those tax the buyer side of a purchase by a foreign entity; s. 116 withholding runs the opposite direction, on the seller side of a sale by a non-resident, and residency for s. 116 is a tax-residency question, not a citizenship or nationality one. Different party, different trigger, different statute in every case — none of these are two names for the same rule.
Because the seller had already started the pre-disposition process before the deal firmed up, the certificate was in hand shortly before closing, and the $65,000 was withheld from the seller's proceeds and remitted directly rather than left as a post-closing exposure sitting with the buyer. Had the certificate not arrived in time, the buyer's lawyer was prepared to hold the $65,000 back in trust pending it — the deal was structured so the 30-day purchaser remittance clock was never actually at risk of starting.
The seller still received less at closing than the sale price suggested, and knew it well in advance, which mattered as much as the number itself: nothing about this outcome was a surprise sprung on either party at the closing table, because the whole timeline had been built around the certificate process from the point the residency question was first raised.
Had the buyer's lawyer closed without confirming a certificate or a trust arrangement, the purchaser — not the seller — would have been the one personally liable to remit $65,000 to the Receiver General within 30 days of month-end, with only a right to try to recover it back from a seller who, by then, could be anywhere in the world. Structuring the closing around the certificate is what kept that exposure off the buyer entirely.
The tell is residency, not nationality or citizenship — and it can be easy to miss because nothing on a standard listing form asks the question directly. Any file where a seller has been living outside Canada for an extended period needs this checked early, given a certificate process measured in months rather than weeks.
