Brokerage cross-border tax: referral fees, Section 116, and US-flagged royalties

Referral fees run both ways, and the direction decides the paperwork

A referral fee your brokerage receives from a US brokerage for sending them a buyer is business income earned in Canada, since the work happened here, so the US payer needs a W-8BEN-E on file to avoid 30% default withholding, and the fee is reported as ordinary Canadian income with the referral service normally zero-rated for GST/HST. Run the same fee in the other direction and the logic flips in your favour: when your brokerage pays a US brokerage or agent for referring a client to you, that agent did the qualifying work on their own side of the border, so there is generally no Canadian withholding obligation on the payment at all. Canada's equivalent rule, Regulation 105, only reaches services actually performed inside Canada by a non-resident.

The paperwork discipline matters either way: collect a W-8BEN-E before you release a referral fee to confirm the US party's status and avoid ambiguity, and make sure any fee you are owed from a US brokerage has your own W-8BEN-E filed before the first payment, not after a 1042-S shows tax already withheld.

Section 116: the Canadian withholding your non-resident sellers may not expect

When a non-resident of Canada, often a US citizen who bought a cottage or condo years ago, sells Canadian real property through one of your listings, Canadian tax law applies its own version of FIRPTA. Under section 116 of the Income Tax Act, the purchaser is generally required to withhold and remit 25% of the gross sale price to CRA unless the non-resident vendor has obtained a clearance certificate before or shortly after closing, which typically limits withholding to a figure tied to the actual gain rather than the full sale price. Because that certificate takes real lead time to arrange, a listing agent who flags the non-resident-seller question the day an offer comes in, rather than the day the file is due to close, saves the deal from a withholding surprise at the lawyer's table. The brokerage's own commission is unaffected by section 116 either way, since the withholding applies to the seller's proceeds, but a deal that stalls waiting on paperwork the seller did not know to start is a deal that can still fall out of escrow, which is reason enough to build the question into your listing intake for any property with an out-of-country seller on title.

FIRPTA literacy still belongs in your training, not just your agents' side hustle

Your agents will keep fielding questions from clients selling US property, and the FIRPTA mechanics, 15% withholding on the gross US sale price, a Form 8288-B application to reduce it, and the ITIN and US return that follow, are covered in depth on our cross-border guide for individual realtors. What changes at the brokerage level is scale: standardizing how every agent flags a cross-border sale early, and pointing clients to a cross-border accountant before an accepted offer rather than after, is a training and process question worth building into your brokerage's onboarding rather than leaving to each agent's individual experience. Agents who hold a dual US licence and actually show property south of the border are a separate case again, since their commissions can become US-source income in their own right — a question we work through with the individual agent rather than at the brokerage level.

An American flag comes with an American royalty question

If your brokerage operates under a franchise brand headquartered in the United States, the monthly royalty and marketing-fund payment is a cross-border withholding event, not just an overhead line. Franchise and trademark royalties paid to a non-resident are generally subject to Canadian non-resident withholding tax under Part XIII, typically reduced to 10% under the Canada-US treaty rather than the default 25%, and the brokerage still has to file an annual NR4 information return reporting the payments and tax withheld even at the reduced rate. Some franchise agreements include a gross-up clause requiring the brokerage to cover the withholding itself so the franchisor receives its full royalty net of tax, worth confirming in your franchise agreement before assuming the 10% simply comes off the top. Reporting the NR4 correctly matters even in a nil-withholding year, since the obligation to file the information return is separate from whether any tax was actually withheld on the payment.
