Canadians expanding into the US often make the same mistake. Because of overlapping media markets, common language and just plain proximity, it is easy for Canadians to assume that what is good for Americans is good for them as well, at least in business. Unfortunately, this is not the case when it comes to choosing a business entity. While US LLCs (Limited Liability Companies) offer flexibility and tax advantages for American owners, they create significant tax and compliance problems for Canadian residents and businesses. The main issue is double taxation—a costly and often unexpected outcome due to conflicting tax treatments between the US and Canada.

Key Reasons Canadians Should Avoid LLCs

1. Double Taxation: The Core Problem

• US Tax Treatment:
  The IRS treats LLCs as “pass-through” entities by default. This means profits are not taxed at the company level; instead, they flow through and are taxed directly on the members’ (owners’) personal tax returns111415.

• Canadian Tax Treatment:
  The Canada Revenue Agency (CRA) does not recognize the US pass-through treatment. Instead, the CRA treats a US LLC as a corporation. This means:

  • Canadian owners are taxed in the US on LLC profits as if they earned them directly.

  • When those profits are distributed to the Canadian owner, the CRA treats them as dividends and taxes them again in Canada1112131517.

• No Foreign Tax Credit:
  Because the US taxes the Canadian owner as an individual and Canada taxes the same income as a corporate dividend, the taxes are not considered the same type. As a result, Canadians generally cannot claim a foreign tax credit for US taxes paid on LLC income, leading to true double taxation111213141517.

  “The ownership of a LLC membership interest by a Canadian is ‘bad’ as LLC income is double taxed, without an available Canadian tax credit. First, LLC income is treated as partnership income for US tax purposes and taxed as such. Second, LLC income is treated by CRA as dividend income and taxed again 11

2. Timing Mismatches

• Income Recognition Differences:
  The US taxes LLC income when it is earned, regardless of whether it is distributed. Canada taxes the income only when it is actually paid out as a dividend. This mismatch can result in further complications and even more double taxation if the timing of distributions and tax years do not align1517.

3. Treaty Limitations

• Canada-US Tax Treaty:
  The Treaty provides relief from double taxation for many types of cross-border income, but does not apply to LLCs because Canada does not recognize them as corporations for treaty purposes. This means LLC income does not benefit from reduced withholding rates or other treaty protections121314.

4. Compliance and Administrative Burdens

• Complex Filings:
  Canadians with US LLCs face complex and costly tax filing requirements in both countries, including additional disclosure forms (e.g., Form T1134 in Canada, Form 5472 in the US)15.

• Potential for Severe Penalties:
  Failure to comply with cross-border reporting rules can result in significant penalties15.

5. Limited Use Cases

• Rare Exceptions:
  There are complex structures (e.g., using a US C-Corp as a “blocker” between the Canadian owner and the LLC) that can mitigate double taxation, but these require advanced planning and professional advice1215. For most Canadian entrepreneurs and small businesses, these structures are unnecessarily complicated and expensive.

Alternatives for Canadians

• US C-Corporation:
  The most common and recommended structure for Canadians is a US C-Corp. Canada recognizes C-Corps as corporations, and the Canada-US Tax Treaty allows for foreign tax credits and reduced withholding rates, preventing double taxation1121316.

• Limited Partnerships (LPs):
  In some cases, using a US limited partnership may be more tax-efficient, especially for real estate investments or passive income. This can be useful, but setting up a limited partnership requires the use of a lawyer to draft the limited partnership agreement, and also requires that there is a general partner with unlimited liability as well as at least one limited partner as an investor.

Summary Table: US LLC vs. C-Corp for Canadians

Conclusion

Canadians should avoid using US LLCs for US expansion or investment because of the high risk of double taxation and lack of treaty protection. The US and Canadian tax systems are fundamentally incompatible when it comes to LLCs, making this structure costly and administratively burdensome for Canadian residents and businesses. A US C-Corp is almost always a better choice, providing clearer tax treatment, access to tax credits, and treaty benefits111121314151617. Always consult a cross-border tax advisor before making your final decision.
