Owner Moves to Florida, Keeps the Canadian Corporation: CFC Rules, the Lost Small Business Rate, and Dividends Across the Border

The owner moves; the corporation stays — and both sides change. The corporation's Canadian status: a corporation incorporated in Canada remains a Canadian resident regardless of where its owner lives (and regardless of where it's managed — a corporation incorporated in Canada is deemed resident, and under the treaty a dual-resident corporation is resident where it was incorporated — paragraph 250(4)(a) and Article IV(3)); but its classification changes — a Canadian-controlled private corporation must not be controlled by non-residents of Canada (or public corporations), so a corporation whose sole shareholder becomes a non-resident ceases to be a CCPC (the subsection 125(7) definition is tested at each moment, so the status ends when the shareholder becomes a non-resident, and subsection 249(3.1) deems the corporation's taxation year to end immediately before that time, with a new year beginning); the consequences: the small business deduction is lost (active business income taxed at the general rate — about 26 to 27 percent combined instead of about 9 to 12 percent — federal 15 percent general and 9 percent small business, so 26.5 percent against 11.2 percent in Ontario from July 1, 2026 (12.2 percent before) and 27 percent against 9 percent in Manitoba), the refundable taxes on investment income (the refundable dividend tax on hand mechanism) no longer apply as they did (a non-CCPC's interest, rent and taxable capital gains are taxed at the general rate — 26.5 percent in Ontario — without the CCPC's additional refundable tax or refundable portion, though Part IV tax on portfolio dividends still applies to a private corporation), and the enhanced investment tax credits for scientific research are reduced; for a business earning C$300,000 of active income, the loss of the small business rate costs about C$45,000 a year of Canadian corporate tax — the price of keeping the corporation with a non-resident owner. Keeping CCPC status — the alternatives: a Canadian-resident family member or partner owning a controlling interest (the definition looks at both de jure control — more than 50 percent of the votes — and control in fact "directly or indirectly in any manner whatever", and treats all non-resident shareholdings as if held by one person, so a minority stake by a Canadian resident doesn't preserve it), or a Canadian holding structure controlled by Canadian residents — each with its own family and governance implications; or accept the general rate, which matters less for a corporation that distributes most of its income each year. The owner's U.S. side — a controlled foreign corporation: the owner, now a U.S. resident (substantial presence or a green card — the snowbird guide's test), owns more than 50 percent of a foreign corporation — a CFC — and the regime applies from the day they become a U.S. person: Form 5471 every year (US$10,000 per form per year for failure — the U.S. citizen owning a Canadian corporation guide), subpart F on the corporation's passive income (the investment portfolio inside it), and the net CFC tested income (GILTI's replacement under P.L. 119-21 for CFC tax years beginning after 2025) on its active income; the corporation's Canadian tax at the general rate (about 26 to 27 percent) exceeds 90 percent of the U.S. corporate rate (18.9 percent), so the high-tax exclusion election excludes the active income from net CFC tested income, and the section 954(b)(4) high-tax exception election excludes passive income from subpart F where it's taxed above 18.9 percent (the loss of the small business rate has a silver lining: the income becomes high-taxed for U.S. purposes, and the CFC inclusions mostly disappear under the election). The pre-move earnings: the earnings the corporation accumulated before the owner became a U.S. person are not taxed by the United States on the move (no inclusion for prior years when the owner wasn't a U.S. shareholder — the one-time section 965 transition tax reached only those who were U.S. shareholders in the corporation's last tax year beginning before 2018, so it doesn't reach a later move); when they are later distributed as dividends to the U.S.-resident owner, they are U.S. dividends (qualified dividends — Canada is a treaty country — taxed at the U.S. capital gains rates, with a foreign tax credit for the 15 percent Canadian withholding); a planning point: distributing the pre-move earnings before the move (taxed in Canada at the resident rates with the dividend tax credit, and not in the United States) or after (Canadian 15 percent withholding plus U.S. qualified dividend tax with the credit) — a comparison that depends on the amounts and the province (the moving a business guide's sequencing). Salary versus dividends after the move: the owner who keeps working for the corporation — managing it from Florida — is paid either a salary or dividends: a salary for services performed in Florida is U.S.-source income to the owner (taxed in the United States; Canada taxes a non-resident's employment income only if the services are performed in Canada — so the salary for Florida work generally isn't Canadian-taxable, though the corporation's deduction for it remains — and under Regulation 104(2) the corporation withholds no Canadian income tax from pay to an employee who is neither resident nor employed in Canada, except on the part attributable to duties performed in Canada); salary for days spent working in Canada is Canadian-source (taxed in Canada, with the treaty's employment article and a U.S. foreign tax credit); dividends carry 15 percent Canadian withholding (NR301 — the NR301 guide) and are U.S. qualified dividends with the credit; the Canada Pension Plan contributions on salary stop for work outside Canada (under the Canada–U.S. social security agreement an employee is generally covered where the work is done, so salary for Florida work carries U.S. Social Security and Medicare, which the Canadian corporation withholds and reports as her U.S. employer — the Canadian employer with U.S. employees guide); the choice affects the corporation's general-rate tax (salary is deductible), the U.S. tax (salary at ordinary rates, dividends at qualified rates), and the GILTI computation. The permanent establishment risk — running it from Florida: if the owner concludes contracts for the Canadian corporation from Florida, or the Florida home office is a place at the corporation's disposal from which it carries on business, the Canadian corporation may have a U.S. permanent establishment — making the profits attributable to the U.S. activities taxable in the United States (Form 1120-F, the branch profits tax — the Canadian company expanding to Florida guide), and creating Florida corporate income tax nexus (the Florida corporate income tax guide); the mitigations: the corporation's contracts negotiated and signed by its Canadian management, the owner's U.S. role limited to oversight, or a U.S. service company (the owner's Florida entity) providing management services to the Canadian corporation for an arm's-length fee — the fee deductible to the Canadian corporation (with Canadian withholding on management fees paid to a non-resident — 25 percent under Part XIII unless the treaty's business profits article exempts it, with a Regulation 105 question if the services are rendered in Canada — the cross-border management fees guide) and income to the U.S. company. The Canadian corporation's other filings: the T2 continues; the change in status is reported on the T2 (the type of corporation at year-end and the date it changed) and Schedule 50 continues to list the owner; the dividends paid to a non-resident are reported on NR4 slips with the Part XIII withholding remitted; and the corporation's books are unchanged otherwise. The bookkeeping: the CCPC status determination at the owner's departure; the corporate rate change; the owner's U.S. residency start date; Form 5471 from the first U.S. year with the high-tax exclusion election; the salary and dividend plan with sourcing by workdays; NR4s and Part XIII remittances; the permanent establishment review and any management services agreement. The errors: the corporation keeps claiming the small business deduction after its owner became a non-resident (a reassessment of the difference with interest); Form 5471 never started; the high-tax exclusion election not made (CFC inclusions on income already taxed at 26 percent); dividends paid to the non-resident owner without Part XIII withholding (the corporation liable); a shareholder loan to her not repaid within one year after the corporation's year-end (subsections 15(2) and 15(2.6) — deemed a dividend to a non-resident under paragraph 214(3)(a), with 15 percent treaty-rate withholding, refundable under subsection 227(6.1) on repayment); and the owner signing the Canadian corporation's contracts from a Florida home office.

Key takeaways

• The corporation stays a Canadian resident, but stops being a CCPC once a non-resident controls it — the small business rate and the refundable investment tax mechanics are lost.
• The U.S.-resident owner owns a controlled foreign corporation — Form 5471 every year, with subpart F and net CFC tested income (formerly GILTI) exposure.
• The silver lining: at the general rate (about 26–27 percent), the corporation's income is high-taxed for U.S. purposes — the high-tax exclusion election removes most of the CFC inclusions.
• Pre-move earnings aren't taxed by the United States until distributed — then they're qualified dividends with a credit for the 15 percent Canadian withholding; distributing some before the move is a modeled option.
• Salary for Florida workdays is U.S.-source; dividends carry Part XIII withholding — the corporation remits it and issues NR4s.
• Running the corporation from Florida risks a U.S. permanent establishment and Florida nexus — keep contract authority in Canada or use an arm's-length management services company.

The kept-Canadian-corporation file

CCPC status at departure; corporate rate change. Owner's U.S. residency start date. Form 5471; high-tax exclusion election; subpart F and GILTI computations. Pre-move earnings distribution plan. Salary versus dividends; sourcing by workdays; NR4 and Part XIII remittances; NR301 on file. Permanent establishment review; management services agreement if used. The CCPC status change is the line most kept corporations miss.

Worked example

A Winnipeg contractor's owner moves to Fort Lauderdale; the corporation (twenty employees, all work in Manitoba) stays, run day to day by its Canadian general manager. The corporation ceases to be a CCPC on her departure (she is its sole shareholder and now a non-resident) — its C$420,000 of active income is taxed at the general rate from that point (about C$75,600 more Canadian tax a year — the 18-point gap between Manitoba's 27 percent combined general rate and its 9 percent small business rate), and its accountant stops claiming the small business deduction. Her U.S. side: Form 5471 from her first U.S. year; with the corporation's income taxed at about 27 percent, the high-tax exclusion election removes it from net CFC tested income — no current U.S. inclusion. She is paid a US$120,000 salary for her oversight work from Florida (U.S.-source, taxed in the United States, with U.S. Social Security and Medicare withheld by the corporation; deductible to the corporation) and C$200,000 of dividends a year (15 percent Part XIII withholding under her NR301 — NR4 slips; U.S. qualified dividends with the credit). The corporation's contracts are negotiated and signed by the Winnipeg general manager — her role from Florida is oversight and strategy, documented — so no U.S. permanent establishment. Her neighbor, who kept his Calgary corporation after moving and kept claiming the small business deduction for three years, faced a reassessment of the rate difference, and a U.S. return with no Form 5471 for the same three years.

Practitioner note

An owner who moves to Florida and keeps the Canadian corporation running changes both companies' tax lives at once: the corporation stops being a CCPC the day a non-resident controls it and loses its small business rate, and the owner becomes a U.S. shareholder of a controlled foreign corporation. Our desks make that rate loss work for the owner — income taxed at the general rate is high-taxed for U.S. purposes, so the high-tax exclusion election removes most of the GILTI and subpart F exposure — set the salary and dividend plan by workdays, withhold Part XIII on every dividend, and keep contract authority in Canada so the Florida home office doesn't become the corporation's U.S. permanent establishment.
