Expanding South?

September 22, 2026
By: Savvas Daginis

Canadian businesses have several options for structuring their United States expansion. The right choice depends on ownership, liability, tax, financing, and the owners’ long-term plans.

Whether the goal is to reach U.S. customers, hire locally, move operations, lower tariffs paid by U.S.-based customers, or prepare for a sale, the first question is often: “How do we incorporate in the United States?” The better starting point is: “What should our U.S. business look like?”

As a U.S. and Canadian business lawyer, I help owners work through that decision. Here are five structures I commonly see, along with key considerations to discuss with your legal and tax advisers. Other structures may also be appropriate.

Sidebar: Do you need a new U.S. corporation? Do you need to register as a foreign corporation in the U.S.?

Not necessarily. Selling to U.S. customers does not automatically require a new entity or registration as a foreign corporation. The requirements depend on your activities and the states involved. Registration, tax filings, and business licences are each separate questions; one does not settle the others.

Remember to ask your business lawyer and CPA for advice before you start selling to U.S. customers or otherwise engaging in business-related conduct in the U.S.

Option 1: Register the Canadian corporation in the U.S.

How it works. The existing Canadian corporation registers as a foreign corporation in the relevant U.S. state or states. “Foreign” means formed outside that state. The Canadian and U.S. operations remain part of the same legal entity.

What to think about. You avoid creating another corporation, but there is no separate entity to contain U.S. business liabilities. Formation costs may be lower, while cross-border tax and compliance costs can still be substantial. Further, litigation in the U.S. can be more expensive than comparable litigation in Canada, particularly in complex commercial disputes. Operating through your existing Canadian corporation also means that claims arising from the U.S. operations are claims against that same corporation, potentially putting its Canadian assets at risk.

Reporting point. Under the current rules of the Financial Crimes Enforcement Network (FinCEN), a Canadian entity registered in the U.S. may have to report beneficial ownership information unless exempt. U.S.-created entities are currently exempt, and foreign reporting companies do not report U.S. persons as beneficial owners.

Option 2: Have the Canadian corporation own a U.S. subsidiary.

How it works. Your Canadian corporation owns shares in a separate U.S. corporation. The Canadian company is the parent; the U.S. company is its subsidiary.

Why consider it? This keeps ownership within the existing corporate group and can help separate U.S. operating liabilities.

What to think about. Plan how the subsidiary will be funded and how profits will return to Canada. Document shared employees, services, intellectual property, and financing in intercompany agreements, with appropriate pricing and tax treatment. Further, U.S.-based investments or operations may cause the Canadian corporation to lose eligibility for certain Canadian tax benefits. For example, holding shares in a U.S. subsidiary may affect whether the Canadian corporation’s shares qualify for the lifetime capital gains exemption when sold. Review the impact with your cross-border tax adviser.

Option 3: Have the shareholders of the Canadian corporation own the U.S. corporation directly.

How it works. The Canadian corporation’s shareholders personally own shares in the U.S. corporation. The two corporations are sister companies under common ownership; the U.S. company is not the Canadian company’s subsidiary.

Why consider it? This keeps the U.S.-based investments or operations outside the existing Canadian corporation and may support planning for a future sale of the Canadian or U.S. business.

What to think about. Funding the U.S. company may require taking money out of the Canadian business first, with tax consequences. Shared resources still need proper agreements. U.S. dividends paid to certain Canadian-resident individual shareholders generally attract a higher withholding tax rate compared to dividends paid to certain corporate shareholders.

Option 4: Use a separate Canadian holding corporation.

How it works. The shareholders keep owning the existing Canadian corporation directly and also own a new Canadian holding company. That holding company owns the U.S. subsidiary but not the existing Canadian corporation.

Why consider it? This keeps the U.S.-based investments or operations outside the Canadian operating company while allowing corporate ownership of the U.S. business. As noted above, certain Canadian corporate shareholders may benefit from a lower dividend withholding rate when they receive dividends from the U.S. subsidiary corporation.

What to think about. The business now has three corporations to maintain. The lower withholding rate is only one part of the calculation: funding, Canadian tax treatment, foreign-affiliate reporting, and eventual payments to individuals also matter. Extra entities do not automatically produce a lower overall tax, legal, and accounting bill.

Option 5: Use a U.S. limited partnership with a corporate general partner.

How it works. A U.S. limited partnership holds the business or investment. A separate U.S. corporation serves as general partner. The limited partners may be the existing Canadian corporation (5A) or its individual shareholders (5B). Ownership percentages require separate planning.

Why consider it? A partnership can accommodate particular investor, financing, or real-estate arrangements. The U.S. corporate general partner helps address the general partner’s liability exposure and keep such exposure within the U.S., among other benefits.

What to think about. Partners can face tax and filing obligations even without cash distributions. A partnership with U.S. business income allocated to foreign partners can also have U.S. withholding obligations.

            Should a Canadian business owner form a U.S. limited liability company (LLC)?

An LLC can make sense in some cross-border structures, but it should not be the default choice simply because it is popular in the United States.

An LLC is a limited liability company. For U.S. federal income tax purposes, it may be treated as a corporation, a partnership, or an entity disregarded as separate from its owner, depending on its ownership and tax elections. With pass-through treatment, the owners generally report the income themselves.

Canada generally treats a U.S. LLC as a corporation. That mismatch can mean the two countries tax different taxpayers or recognize income at different times. This can complicate tax filings, limit foreign tax credits or treaty relief, and potentially result in double taxation.

Before forming any LLC, be sure to speak to your business lawyer and CPA.

            What should you decide before incorporating?

Who will own and fund the business? Decide whether ownership belongs with the Canadian corporation, individual shareholders, a holding company, or investors. Trace where the startup money will come from.

Where will the work happen? Identify employees, management, customers, inventory, and premises. These facts influence state registrations, payroll, tax filings, and licences.

What will move across the border? Plan how equipment will be transferred or leased, contracts will be assigned, and services will be provided across the border. If tariffs are part of the motivation, obtain customs advice on the actual goods and supply chain; incorporation alone does not resolve tariff exposure.

Who will own the intellectual property used in Canada and the U.S.? Decide which entity will own your trademarks, software, product designs, and other intellectual property, and whether the other entity will need a licence to use them. Address ownership of new developments as well. These arrangements should support your plans for growth or a sale, with legal and tax advice before transferring intellectual property across the border.

How will you bring U.S. profits back to Canada? Plan how funds will flow to the Canadian business or its shareholders, whether through dividends, payments for services or intellectual property, or repayment of financing. Each route has different tax consequences and documentation requirements. Payments should reflect the actual arrangements between the parties, with cross-border tax advice guiding the approach.

What will the structure cost to maintain? Compare ongoing legal, accounting, tax-compliance, registered-agent, and annual filing costs, as applicable. Consider the cost of restructuring or selling later, too. The cheapest entity to form may be expensive to operate or unwind.

Will anyone relocate? Owning a U.S. company does not itself authorize you to live or work in the United States. Coordinate immigration and personal tax advice before moving.

            Choose the structure before filing the paperwork.

The right structure should support the business you are building, protect what you are keeping in Canada, and leave room for your next step. Coordinate U.S. and Canadian legal advice with cross-border tax advice before committing to an entity or moving assets.
