Canadian Company Expanding to Florida: Subsidiary or Branch, Permanent Establishment, Transfer Pricing, and the First U.S. Hire

A Canadian company's first Florida sale is usually easy; its first Florida office is where the tax structure starts. Stage one — selling without a permanent establishment: a Canadian company selling to Florida customers from Canada (shipping goods, providing services remotely, sending salespeople on short trips) has no U.S. permanent establishment under the Canada–U.S. treaty (the treaty guide — Article V: a fixed place of business in the United States, a dependent agent who habitually concludes contracts in the company's name, or services deemed a permanent establishment under Article V(9) — an individual present in the United States 183 days or more in any twelve-month period whose U.S. services produce more than 50 percent of the company's gross active business revenues in that period, or services provided in the United States for 183 days or more in any twelve-month period on the same or connected project for U.S.-resident customers or customers' U.S. permanent establishments), so its business profits are taxed only in Canada (Article VII) — but it may still have a U.S. filing: a Canadian corporation engaged in a U.S. trade or business (a lower threshold than a permanent establishment — regular, continuous U.S. business activity) files Form 1120-F and claims the treaty's protection on a protective or treaty-based return (with Form 8833 disclosing the position that the company's U.S. business profits aren't attributable to a permanent establishment — a disclosure Reg. 301.6114-1(b)(5)(i) specifically requires; the protective return itself is under Reg. 1.882-4(a)(3)(vi)) — and a company that doesn't file a timely Form 1120-F can lose its deductions if the IRS later finds effectively connected income (the protective filing preserves them); state nexus is a separate question — Florida corporate income tax nexus for a Canadian company with Florida sales (the treaty doesn't bind the states — the treaty guide), and sales tax registration for goods shipped to Florida customers once the economic threshold is crossed (Florida's remote seller threshold — more than US$100,000 of taxable remote sales of tangible personal property into Florida in the previous calendar year, under s. 212.0596, in effect since July 1, 2021). Stage two — the office and the people: once the Canadian company has a Florida office, employees, or a dependent agent, it has a permanent establishment, and the question is the vehicle. The branch: the Canadian corporation itself operates in Florida (registered as a foreign corporation with the Division of Corporations — the Florida annual report guide); the branch's profits are taxed in the United States (Form 1120-F on effectively connected income, at the 21 percent federal rate, plus Florida corporate tax on its Florida-apportioned share — the Florida corporate income tax guide), and the United States imposes a branch profits tax (30 percent under section 884, reduced by Article X(6) of the treaty to 5 percent of the branch's after-tax earnings not reinvested in the U.S. business, after a cumulative exemption for the first C$500,000 of earnings — or its U.S.-dollar equivalent — shared with associated companies in the same or a similar business); Canada taxes the Canadian corporation on its worldwide income including the branch's, with a foreign tax credit (or a deduction) for the U.S. tax; the branch's losses reduce the Canadian corporation's Canadian taxable income directly — the branch's advantage in a start-up period; the branch's disadvantages are the U.S. liability exposure of the whole Canadian corporation and the U.S. filings of the parent itself. The subsidiary: the Canadian company forms a U.S. corporation (a Delaware or Florida corporation — a C corporation, since an S corporation can't have a corporate shareholder — the LLC-to-C-corp guide's context) that operates the Florida business; the subsidiary pays U.S. federal tax on its own income (Form 1120) and Florida corporate tax; its dividends to the Canadian parent carry U.S. withholding (30 percent, reduced by the treaty to 5 percent for a parent owning 10 percent or more of the voting stock — the NR301 guide's mirror, from the U.S. side — Form W-8BEN-E from the parent), and Canada's foreign affiliate rules (the subsidiary's active business income forms exempt surplus when it is earned by an affiliate resident in, and carrying on business in, a designated treaty country such as the United States, so dividends paid out of it are deductible to the Canadian parent and effectively received tax-free); the subsidiary's losses stay in the subsidiary (no Canadian deduction); the advantages are the liability wall (the U.S. operation's liabilities stay in the subsidiary), the clean U.S. presence for customers, lenders, and landlords, and the parent's freedom from U.S. filings as a branch. The U.S. LLC — the hybrid trap: a Canadian company that forms a U.S. LLC as its subsidiary gets a disregarded entity for U.S. tax (the LLC's income is the Canadian parent's effectively connected income — a branch in U.S. tax terms, with Form 1120-F and the branch profits tax) but a corporation for Canadian tax (Canada treats an LLC as a corporation — a foreign affiliate), and the treaty's anti-hybrid rules (Article IV(7)(a) — income a Canadian company derives through an entity the United States disregards but Canada treats as a corporation is treated as not derived by a Canadian resident) can deny treaty benefits on the LLC's income — the 5 percent branch profits rate and the C$500,000 exemption included, leaving the 30 percent statutory branch profits tax; the LLC is usually the wrong vehicle for a Canadian parent unless it elects to be taxed as a corporation (Form 8832) — the Canadian owner of a U.S. LLC guide covers the individual version. Transfer pricing: the subsidiary and the parent transact — the parent sells goods to the subsidiary for resale, licenses its software or brand, provides management services, lends money — and both countries require arm's-length pricing (section 482 in the United States, section 247 in Canada), with documentation (penalty protection in both countries depends on contemporaneous documentation: in the United States the section 6662(e) penalty applies when net section 482 adjustments exceed the lesser of US$5 million or 10 percent of gross receipts, with documentation in existence when the return is filed and produced within 30 days of an IRS request; in Canada the section 247(3) penalty — 10 percent of the adjustment — applies above the lesser of 10 percent of gross revenue and C$10 million for taxation years beginning after November 4, 2025 (C$5 million before), with documentation prepared by the return's filing-due date and produced within 30 days of a CRA request, down from three months), and a pricing policy set before the first intercompany invoice; the subsidiary files Form 5472 reporting its transactions with its foreign parent (the US$25,000 penalty for failure — the IRS's form), and the Canadian parent files Form T106 for its transactions with non-arm's-length non-residents (required when those transactions total more than C$1 million in the year). The first U.S. hire: a U.S. employee is on a U.S. payroll — the subsidiary (or the branch) obtains an employer identification number, registers with Florida for reemployment tax (the Florida reemployment tax guide), withholds federal income tax and FICA, and files Forms 941 and W-2; a Canadian employee sent to Florida to work is a separate question (the Totalization Agreement's certificate of coverage — CRA Form CPT56, for an assignment expected to last 60 months or less — keeps the employee in the Canada Pension Plan and out of U.S. Social Security and Medicare tax; U.S. income tax on U.S.-source wages under the treaty's employment article — the treaty guide's US$10,000 and 183-day rule; the immigration status — an L-1 or TN, which is the employer's gating question); an employer of record (a professional employer organization — the staffing agency taxes guide's PEO) is a stopgap for a first hire before the entity exists. The Florida layer: the subsidiary or branch registers with the Division of Corporations, obtains the local business tax receipts (the Florida local business tax guide), files the tangible personal property return (the Florida tangible personal property tax guide), and pays Florida corporate income tax on its Florida-apportioned income — Florida has no personal income tax, but the subsidiary is a C corporation and pays. The decision in practice: most Canadian small and mid-sized companies expanding to Florida form a U.S. C corporation subsidiary — the liability wall, the clean U.S. presence, and the exempt-surplus treatment of its dividends outweigh the branch's use of start-up losses — unless the U.S. operation will lose money for years and the Canadian company needs the losses in Canada, in which case a branch for the start-up period, converted to a subsidiary later (a transfer with its own tax consequences — the U.S. side can usually be a tax-free section 351 incorporation, but Canada has no rollover for assets transferred to a foreign corporation, so the parent recognizes any accrued gain on the branch's assets), is modeled.

Key takeaways

• No permanent establishment, no U.S. tax on business profits under the treaty — but a Canadian company engaged in a U.S. trade or business files a protective Form 1120-F to preserve its deductions, and Florida nexus and sales tax are separate questions the treaty doesn't answer.
• A branch puts the Canadian corporation itself on Form 1120-F, adds the branch profits tax (5 percent under the treaty, with an exemption for the first C$500,000 of cumulative profits), and passes start-up losses to the Canadian return.
• A U.S. C corporation subsidiary walls off the U.S. liabilities, pays U.S. and Florida corporate tax, and pays dividends to the parent at 5 percent treaty withholding — received as exempt surplus in Canada.
• A U.S. LLC is usually the wrong vehicle for a Canadian parent — disregarded in the United States, a corporation in Canada, and exposed to the treaty's anti-hybrid rules — unless it elects corporate status.
• Transfer pricing between parent and subsidiary must be arm's length and documented in both countries; the subsidiary files Form 5472 and the parent Form T106.
• The first U.S. hire needs a U.S. payroll and Florida reemployment registration; a Canadian employee sent south needs a coverage certificate and an immigration status first.

The Canadian company's Florida expansion file

Permanent establishment analysis; protective Form 1120-F and Form 8833 if engaged in a U.S. trade or business without a PE. Vehicle: branch (1120-F, branch profits tax) or C corporation subsidiary (1120, dividends via W-8BEN-E); LLC only with a corporate election. Transfer pricing policy and documentation; Form 5472; Form T106. Florida: foreign qualification, corporate income tax, local business tax receipts, tangible personal property return, sales tax registration. Payroll: EIN, Florida reemployment tax, Forms 941 and W-2; secondees' coverage certificates and immigration. The vehicle decision comes first and shapes every other line.

Worked example

An Ontario software company with C$6 million of revenue sells to Florida customers from Toronto for two years — no permanent establishment (no U.S. office, no U.S. employees, salespeople visiting for a few days at a time); it files a protective Form 1120-F each year with Form 8833 disclosing the treaty position, and has no Florida sales tax registration to make — Florida generally doesn't tax software as a service or electronically delivered software (Department of Revenue TAA 16A-014), and the remote seller threshold counts only taxable sales of tangible goods. In year three it opens a Miami office with four salespeople: it forms a Delaware C corporation, qualifies it in Florida, and the subsidiary resells the parent's software under an intercompany distribution agreement priced at a documented arm's-length margin (a transfer pricing study from year one); the subsidiary's US$300,000 of profit pays federal tax at 21 percent and Florida corporate tax on its apportioned income; its first dividend to the parent carries 5 percent U.S. withholding (a W-8BEN-E on file) and arrives in Canada as exempt surplus; the subsidiary files Form 5472 and the parent Form T106. Its Canadian sales director, sent to Miami for eighteen months to build the team, holds an L-1 visa, a certificate of coverage under the Totalization Agreement keeping her in the Canada Pension Plan, and U.S. payroll for her Florida work. A competitor that formed a Florida LLC for the same purpose found it had become a U.S. branch of its Canadian parent for U.S. tax — the parent filing Form 1120-F and owing branch profits tax — while Canada treated the LLC as a foreign corporation.

Practitioner note

A Canadian company's Florida expansion is decided by one question before any other: will it have a U.S. permanent establishment, and if so, through what vehicle. Our U.S. and Canadian desks model the branch against the C corporation subsidiary together — the branch's start-up losses in Canada against the subsidiary's liability wall and exempt-surplus dividends — steer Canadian parents away from the U.S. LLC's hybrid problems, set the transfer pricing before the first intercompany invoice, and build the Florida layer (qualification, corporate tax, sales tax, reemployment) alongside, because Florida's missing personal income tax does nothing for a subsidiary that is a C corporation.
