Cross-border tax for gas stations: US brands, station groups, US-citizen owners

The fuel stays domestic; the money does not

Most Ontario stations buy fuel from Canadian refiners and distributors, so the product itself raises no customs questions. The border shows up in the contracts and the ownership instead: a branded supply agreement with a US company, USD incentive and rebate payments, a station group whose corporations hold US bank or investment accounts, and — very often in the GTA — an owner who happens to be a US citizen or green-card holder. This page covers those three flows; the domestic side of the file lives with our gas station tax services.

Paying a US brand: goods, royalties, and Part XIII

What you pay for determines whether you must withhold. Payments for fuel and merchandise are payments for goods — no Canadian withholding applies, and the only accounting job is converting USD invoices to Canadian dollars consistently. But where an agreement charges separately for the use of a US company's trademark, brand image or system, that slice is a royalty to a non-resident, and Part XIII of the Income Tax Act requires the Canadian payer to withhold — 25 percent by default, generally reduced to 10 percent on royalties under the Canada-US treaty when the US payee certifies its entitlement.

The withholding is your obligation, not the US company's. Miss it and CRA assesses the station, with interest — and many US agreements contain gross-up clauses that push the entire cost onto you by requiring the US party to receive its fee net of any tax. We read the agreement, split goods from royalties, remit on time and file the NR4 slips that report the payments. Rebates and image-program incentives flowing the other way are simply income — recognized when receivable, converted at the exchange rate that matches your bookkeeping policy.

Station groups: multi-entity structures with cross-border edges

Most multi-site operators hold each station in its own corporation, often under a holding company. Domestically that is an associated group sharing one $500,000 small business deduction — familiar ground. The cross-border edges are less familiar:

• T1135 reporting — a corporation whose specified foreign property (US bank accounts, US brokerage investments, US real estate that is not personal-use) exceeds $100,000 CAD in cost must file Form T1135 every year. Penalties start at $25 a day and run per entity, so a five-corporation group can multiply one oversight by five.
• Passive US income inside a corporation — US interest, dividends or rental income earned by a foreign affiliate structure can raise FAPI questions. Most station groups never get there, but the moment US entities enter the chart we map it properly.
• USD balances — US-dollar accounts and intercompany balances create foreign exchange gains and losses that must land in the right corporation, not wherever the bookkeeping software defaults.

US-citizen owner-operators: filing both sides

A US citizen who owns a Canadian gas station corporation files in both countries for life, regardless of where they live. The Canadian T1 and corporate T2 are only half the file. The US half typically includes a Form 1040 on worldwide income, FBAR (FinCEN 114) covering Canadian accounts — including corporate accounts they control — and Form 5471 for the Canadian corporation itself, with GILTI rules potentially taxing retained corporate earnings in the US even when nothing is paid out.

This is why the standard Canadian playbook cannot be copied blindly. Dividend timing, holding-company reorganizations and the lifetime capital gains exemption on an eventual station sale all read differently on a US return — the LCGE, for one, does not exist in the US system. We plan compensation and structure with both returns on the desk, alongside the rest of our cross-border tax practice.

Catch it in the contract, not in the audit

Every item above is cheap to handle prospectively and expensive to fix retroactively. We review supply and brand agreements before signing, set the withholding and NR4 calendar, screen the group annually for T1135, and coordinate with US preparers — or prepare both sides — for US-citizen owners. Boutique firm, cloud-first, fixed fees quoted after a discovery call.
