Starting a Business in Canada as a US Citizen or US Resident: The CCPC You Won't Get, the CFC You Will, and the Structures That Work

A US person starting a business in Canada faces the mirror image of the Canadian who starts one in the US. The natural Canadian vehicle, a Canadian-controlled private corporation with its small business rate, is unavailable to a corporation controlled by a non-resident, and a US citizen resident in Canada who forms a Canadian corporation gets the CCPC in Canada and a controlled foreign corporation in the US. The alternatives (a branch of a US company, a Canadian unlimited liability company, a sole proprietorship) each trade one problem for another. The owner's residence and citizenship decide the structure, and the immigration status decides whether the owner can work in the business at all.

Key takeaways

• CCPC status: a Canadian corporation controlled by non-residents (directly or indirectly, by a US resident or a US corporation) is not a CCPC: no small business deduction (the general rate of about 26% to 27% applies from the first dollar), no enhanced investment tax credits, no lifetime capital gains exemption on its shares. A corporation controlled by a Canadian resident who is a US citizen is a CCPC (residence, not citizenship, controls).
• CFC status: a Canadian corporation more than 50% owned by US persons (citizens or residents) is a controlled foreign corporation for US purposes: Form 5471, Subpart F on passive income, the GILTI regime on active income (often relieved by the high-tax exception, but not at the small business rate), and a section 367 issue if property is rolled in.
• Branch: a US corporation can carry on business in Canada directly; if it has a permanent establishment, it files a Canadian T2 (with Schedule 97) on the attributable profits at the general rate and pays branch tax at the treaty rate of 5% on after-tax profits not reinvested. No CCPC, no CFC (the US corporation is the taxpayer), but Canadian registration and reporting.
• ULC: an Alberta, BC, or Nova Scotia unlimited liability company gives a US owner flow-through treatment in the US while Canada taxes it as a corporation; the treaty's anti-hybrid rule can deny treaty benefits on distributions unless structured carefully.
• Registrations: federal or provincial incorporation; extra-provincial registration where business is carried on; a CRA business number with corporate tax, GST/HST (above $30,000), and payroll accounts; provincial sales tax where applicable. A US person needs a work permit or permanent residence to work in the business in Canada.

The CCPC problem

A Canadian-controlled private corporation is a private corporation resident in Canada that is not controlled by non-residents, public corporations, or a combination. Control is de jure (voting shares) and can be de facto. A Canadian corporation owned 60% by a US resident is not a CCPC: its active business income is taxed at the general combined rate (about 26.5% in Ontario) rather than the small business rate (about 12.2% on the first $500,000). It cannot claim the enhanced SR&ED credit, and its shares are not qualified small business corporation shares for the lifetime capital gains exemption.

A US citizen who is resident in Canada is not a non-resident, so a corporation they control is a CCPC. Citizenship is irrelevant to CCPC status; residence is what counts.

The CFC problem

For US purposes, a foreign corporation more than 50% owned by US shareholders (US persons owning 10% or more) is a CFC. A US citizen in Canada who forms a Canadian corporation has a CFC from day one: annual Form 5471 with schedules; Subpart F inclusion of passive income; GILTI (net CFC tested income) inclusion of active income, with the high-tax exception available only if the Canadian rate exceeds 18.9%, which the small business rate does not reach. A CCPC's small-business-rate income is therefore included in the US shareholder's income annually under GILTI (with the section 962 election available for the 40% deduction and 90% credit). The US tax on GILTI at the small business rate can approach the difference between the Canadian small business rate and the US corporate rate, eroding the CCPC advantage.

A US resident (not a citizen) who owns a Canadian corporation from the US has the same CFC status.

The alternatives

Branch. A US corporation carries on the Canadian business directly (a Canadian office, employees, contracts). It has a Canadian permanent establishment and files a Canadian T2 on the profits attributable to it at the general rate, plus branch tax (25% domestically, 5% under the treaty after a $500,000 CAD cumulative exemption) on after-tax profits not reinvested. The US corporation reports the Canadian income on its US return with a foreign tax credit. No Canadian entity, no CCPC question, no CFC (the US corporation is the taxpayer, not a shareholder in a foreign corporation). Canadian registration as an extra-provincial corporation, a business number, GST/HST, and payroll are required. Liability is not ring-fenced.

ULC. An unlimited liability company under Alberta, BC, or Nova Scotia law is a corporation in Canada (taxed as one, not a CCPC if non-resident controlled) and can be a disregarded entity or partnership in the US by check-the-box election. A US owner gets flow-through US treatment (Canadian corporate tax creditable against the owner's US tax on the same income) without a CFC. The treaty's Article IV(7)(b) denies treaty benefits on amounts (dividends, interest) paid by the ULC to a US resident where the US treats the ULC as fiscally transparent, so distributions face 25% Canadian withholding unless structured as a paid-up capital increase and reduction (a common workaround). ULC shareholders have unlimited liability for the company's obligations on liquidation.

Sole proprietorship or partnership. A US person resident in Canada can run the business unincorporated: Canadian tax at personal rates on T2125; US tax on Schedule C with a foreign tax credit; no CFC, no Form 5471, no section 367; CPP under the totalization agreement, no US self-employment tax. The small business deduction is forgone. For many US-citizen professionals in Canada, this is the answer.

Canadian corporation anyway. A US citizen resident in Canada who wants the CCPC's small business rate accepts the CFC compliance: Form 5471 annually, the GILTI inclusion (mitigated by the section 962 election and, where the Canadian rate exceeds 18.9%, the high-tax exception), and the section 367 analysis on any rollover. The corporation's investment income is Subpart F income taxed at about 50% in Canada, above the high-tax threshold. The structure works with planning and costs several thousand dollars a year in US compliance.

Registrations and the permit

Incorporate federally (CBCA) or provincially; register extra-provincially in each province where business is carried on; obtain a CRA business number with a corporate income tax account, a GST/HST account once taxable supplies exceed $30,000 (or voluntarily earlier), and a payroll account for employees; register for provincial sales tax in BC, Saskatchewan, Manitoba, and Quebec where applicable. A director's residency requirement applies to CBCA corporations (25% Canadian-resident directors) and some provinces; BC, Alberta, Ontario, and Quebec have none.

A US citizen or resident who will work in the Canadian business needs immigration status that permits it: a work permit (an intra-company transferee permit for a US company opening a Canadian branch or subsidiary; a CUSMA professional or investor permit), or permanent residence. Owning a Canadian corporation does not confer the right to work in Canada.

Worked example

A Miami software company wants to serve Canadian clients with a Toronto office and two Canadian employees.

• Branch. The Florida corporation registers in Ontario, opens a business number, GST/HST, and payroll; files a Canadian T2 on the Toronto office's profits at 26.5% plus 5% branch tax on repatriated profits; claims a foreign tax credit on the US return. Simple; no second entity; liability exposure.
• Canadian subsidiary. An Ontario corporation owned by the Florida corporation: not a CCPC (non-resident controlled); 26.5% on its profits; 5% withholding on dividends to the parent; Form 5471 for the parent (a corporate US shareholder; GILTI with the corporate deduction and credit; high-tax exception available at 26.5%); T1134 not required (the parent is US). Cleaner liability; more filings.
• ULC. An Alberta ULC owned by the Florida corporation, disregarded for US purposes: Canadian corporate tax at the general rate; no CFC; flow-through US treatment; distributions structured through paid-up capital to avoid the anti-hybrid withholding. Common for US parents.
• The owner. The Florida company's founder working in Toronto needs an intra-company transferee work permit.

Practitioner note

The US person starting a Canadian business loses the CCPC if they are not a Canadian resident and gains a CFC if they are a US person, and the two problems do not cancel out. For a US citizen resident in Canada, the honest comparison is the CCPC with Form 5471 and GILTI against the unincorporated business with neither, and the unincorporated business wins more often than Canadian accountants expect. For a US company, the branch or the ULC usually beats the subsidiary.
