US Business with Canadian Ties

Canadians who move to the US and start a business, or US residents who maintain Canadian business connections, must navigate permanent establishment rules, transfer pricing, and cross-border service sourcing. A US business can inadvertently create a Canadian tax obligation if it has a permanent establishment in Canada or earns Canadian-source business income.

Key Points

  • A permanent establishment (PE) in Canada triggers Canadian corporate or business tax on profits attributable to the PE.
  • Under the treaty, business profits are taxable only in the country of residence unless there is a PE in the other country.
  • Common PE triggers include a fixed place of business, a dependent agent, or a construction site lasting more than 12 months.
  • Cross-border services performed in Canada for more than 183 days in any 12-month period can create a deemed PE.
  • Transfer pricing rules apply to transactions between related Canadian and US entities.
  • GST/HST registration may be required if you supply taxable goods or services in Canada.

Action Items

  1. 1.Assess whether your US business activities in Canada could create a permanent establishment.
  2. 2.Structure client engagements to stay below the 183-day service PE threshold where possible.
  3. 3.Maintain arm's-length pricing for any transactions between your US business and Canadian related parties.
  4. 4.Register for GST/HST if required due to Canadian-source supplies exceeding $30,000.
  5. 5.Report all business income on your US return and claim foreign tax credits for any Canadian taxes paid.
  6. 6.Consult a cross-border business tax advisor on entity structuring (LLC, S-Corp, C-Corp) and treaty implications.

Frequently Asked Questions

Does selling to Canadian customers create a permanent establishment?

Not necessarily. Selling goods or services to Canadian customers from the US without a fixed place of business or dependent agent in Canada generally does not create a PE. However, if you have employees or an office in Canada, a PE may exist.

Can I use a Canadian LLC or sole proprietorship for my US business?

Canada does not have LLCs. A Canadian sole proprietorship or corporation would create a Canadian filing obligation. Most US-based entrepreneurs should use a US entity and manage Canadian exposure through proper structuring.

What are the consequences of having an unintended permanent establishment in Canada?

You would owe Canadian income tax on profits attributable to the PE, need to file Canadian corporate or personal returns, and potentially register for GST/HST. Foreign tax credits would offset double taxation on the US side.

TFSA US Tax Trap

The Tax-Free Savings Account is tax-exempt in Canada but receives no treaty protection in the US. The IRS classifies a TFSA as a foreign grantor trust, requiring Forms 3520 and 3520-A annually. Failure to file can result in penalties starting at $10,000 per form per year.

Critical

FBAR Filing Requirements

The Report of Foreign Bank and Financial Accounts (FBAR) must be filed by any US person with foreign financial accounts exceeding $10,000 in aggregate at any point during the year. The FBAR is filed electronically with FinCEN, not the IRS, and has its own deadline and penalty regime.

Core

Substantial Presence Test

The Substantial Presence Test (SPT) uses a weighted formula across three years to determine if a foreign national is a US tax resident. If you meet the test, you are taxed on worldwide income. Understanding the SPT is essential for snowbirds and anyone splitting time between Canada and the US.
