Restaurant cross-border tax: royalties to a US franchisor make you the tax collector

The franchisee is the withholding agent

When a Canadian restaurant pays franchise royalties to a US franchisor, the Income Tax Act makes the restaurant responsible for the tax. Part XIII imposes 25% on royalties paid to non-residents; the Canada–US treaty cuts that to 10% for typical franchise royalties, but only once the franchisor has given you a declaration of treaty eligibility (the NR301 series). You deduct the tax from each payment, remit it to CRA by the 15th of the following month, and file NR4 slips and an NR4 Summary by March 31.

The enforcement mechanics are what make this dangerous. The franchisor was paid in full and is gone; if no one withheld, CRA assesses you for the un-remitted tax, adds a 10% penalty plus interest, and can reach back through several years at once. The most common discovery points are a CRA audit and — worse — due diligence when you try to sell the restaurant, where the accumulated liability lands straight on the purchase price.

Gross-up clauses quietly raise your royalty rate

US franchise agreements routinely require that royalties arrive "free and clear" of any withholding. That clause does not cancel Part XIII — no contract can — it just makes the tax your cost. The math: a 5% royalty on an $80,000 month is $4,000; to net the franchisor $4,000 after 10% withholding you must pay $4,444 and remit $444, so your true royalty rate is about 5.6% of sales.

Budget that difference into your food-cost and labour targets, because it never appears in the franchise disclosure document's headline rate. And raise it at renewal: the franchisor can generally claim a US foreign tax credit for the Canadian tax withheld, so a hard gross-up clause lets them collect the same dollar twice. Franchisors negotiate this more often than franchisees assume — but only when someone asks.

Not every line on the franchise invoice is a royalty

Part XIII treatment follows what a payment is for, not what the invoice calls it. Getting the characterization in writing — from the franchisor and in your file — is what stands up under audit.

The advertising-fund line is where we see the most inconsistency between franchise systems, and the dollars are material — brand funds often run 2% or more of gross sales. We review the agreement's characterization before the first remittance, not after three years of doing it wrong in either direction.

Running the pipes the other way: US expansion

When a Canadian concept works well enough to franchise or open corporately in the US, the same cross-border machinery runs in reverse — and entity choice is the decision that is expensive to undo. A US LLC is a known trap for Canadian owners: the US taxes its members while CRA treats it as a corporation, and the mismatch produces double tax. A US C-corporation under your Canadian company is the usual starting point, with state sales tax registration replacing HST, transfer-pricing support for any management fees the Canadian side charges, and treaty withholding on dividends coming home.

None of that should be improvised off the back of a strong second location. We model the structure alongside the unit economics as part of CFO services for restaurant owners, so the expansion decision and its tax wrapper get made together.
