US LLC for Canadians: 5 Reasons It Can Make Sense

A US LLC is quick and cheap to open, which is why so many Canadian owners open one. The harder question is whether it fits how your business earns money. The IRS usually looks straight through a single-owner LLC to its owner. The CRA treats the same LLC as a foreign corporation. When the fit is right, that gap is manageable. When it is wrong, it shows up on your tax bill and your filing calendar every year.

What you will learn

Five situations where a US LLC earns its place, the condition each one depends on, and the mistake that turns a useful tool into an expensive one. Still deciding whether to sell into the US at all? Start with Selling Into the US? 5 Questions Before Your First Invoice.

Five reasons a US LLC can make sense

1. 1. It gives you a US identity for banking and payments

   Some US banks, payment processors and marketplaces onboard a US entity more easily than a Canadian one. An LLC with its own US federal tax number (an EIN) can hold US dollars, collect from US customers and pay US suppliers without routing every dollar through Canada.

   The condition: Platform and bank rules change often, so confirm them before you build around one. The payoff is fewer currency conversions on every US sale.

2. 2. It keeps US risk in a US box

   A US customer dispute or product claim generally stays with the US entity, not your Canadian company's assets.

   The condition: The separation holds only if the LLC runs as a real business: its own bank account, its own contracts, no mixing of funds. Done properly, a US lawsuit reaches the LLC's working capital, not your Canadian retained earnings.

3. 3. US buyers and partners know how to sign with it

   US wholesalers, distributors and co-investors are used to contracting with a US entity under US state law. A multi-member LLC is also a familiar vehicle for a joint venture with a US partner, because its operating agreement can be shaped around the deal.

   The condition: It pays off only if you actually sign US contracts. When you do, less friction over whose law applies means fewer deals stalled at the contract stage.

4. 4. Owned by your Canadian corporation, profit can be taxed once

   If the work happens in Canada and the LLC has no US office, staff or warehouse, the profit usually belongs in Canada. Intercompany charges priced at arm's length and properly documented can line the profit up with where the work is done, so it is taxed once, inside your corporation.

   Ontario's small business rate drops to 2.2% on July 1, 2026, for a combined federal and Ontario rate of 11.2% on the first $500,000 of active business income.^[1]

   The condition: That rate is a deferral, not a final rate: personal tax applies when you pay yourself. And an LLC managed entirely from Toronto can be treated by the CRA as resident in Canada, which changes the answer.

5. 5. It is a building block for bigger structures

   Separate LLCs can hold separate US assets, so trouble at one property does not reach the others. Many cross-border structures place those LLCs under a US corporation owned by a Canadian holding company. Under the Canada-US tax treaty, US withholding on dividends to a Canadian corporation that owns at least 10% of the votes falls from 15% to 5%.^[2]

   The condition: Passive income such as rent is taxed in Canada as it is earned when it sits in a foreign corporation you control. What sits above the LLC decides whether US tax paid offsets that Canadian tax.

The decision underneath

None of these reasons is about forming an LLC. Each one is about who owns it, where the work happens and where the profit should land. Large companies treat a new foreign subsidiary as a board-level decision, modelled in both countries before anything is signed. Small businesses often treat it as a website checkout.

At Bibeka, we read the LLC the way a corporate tax department would: what the IRS will see, what the CRA will see, and what reaches your bank account after both. The decisions stay yours. The point is making them on your numbers, not on a formation site's promise.

What owners miss: the filings

The most common cost is not tax. It is a missed form. A foreign-owned single-member LLC must file IRS Form 5472 with a pro forma Form 1120 each year, even with no revenue. The IRS penalty for missing it starts at $25,000 USD per form. In Canada, the owner generally files Form T1134, due 10 months after year-end. CRA penalties run $25 a day up to $2,500, and up to $12,000 where the failure is knowing or grossly negligent.^[3][4][5]

One more gap applies when you own the LLC personally. The US taxes the profit as it is earned; Canada taxes it when it is paid out, as a foreign dividend. Because the timing and the type of income differ, US tax may not be fully credited in Canada. That gap can be planned around. Left alone, you pay for it.

Three questions before you open one

1. If your LLC made $100,000 this year, do you know what each country would tax, and when?
2. Should the LLC be owned by you, by your Canadian corporation, or sit under a US corporation?
3. Who on your team owns the Form 5472 and T1134 deadlines, and the penalties if they slip?
