Your Canadian Corporation After You Move to the US: CCPC Status Lost, CFC Status Gained, and the Windows That Close at Departure

Short version: What Is a Controlled Foreign Corporation (CFC)?

The owner crosses the border; the corporation stays; and both tax systems reclassify it anyway. On the Canadian side, a corporation controlled by a non-resident ceases to be a Canadian-controlled private corporation the moment its controlling shareholder emigrates — and CCPC status is where the goodies live: the small business deduction (the roughly 9-12% combined rate on the first C$500,000 of active income becomes the general rate around 26-27%), the lifetime capital gains exemption on qualifying share sales (unavailable to a non-resident vendor in the ordinary course anyway, and the shares stop accruing qualification), refundable investment-income mechanics, and enhanced R&D credits. A deemed year-end accompanies the status change, splitting the fiscal year. On the US side, the same emigration usually makes the company a controlled foreign corporation — a foreign corporation majority-owned by US shareholders — which drapes the owner's 1040 in Form 5471 (a return-sized information filing with four-figure penalties for lateness), GILTI (current US taxation of most of the company's active earnings, softened but not eliminated by the section 962 election and the deduction/credit mechanics), and Subpart F on passive income. Meanwhile the shares themselves went through the departure tax at fair market value (the T1244 deferral is standard here), and the corporation's mind-and-management should be examined — a company actually run from Florida risks becoming factually resident outside Canada, adding a corporate emigration problem to the personal one. The pre-departure window is where the options live: purify and crystallize while the exemption and CCPC status exist, strip surplus at Canadian dividend rates you will never see again, or restructure the ownership so the border crossing doesn't drag the company with you.

Key takeaways

• CCPC status ends at emigration of control: deemed year-end; small business deduction gone (active income now at general rates); LCGE qualification effectively ends — the exemption is a use-it-before-departure asset, claimable via a pre-departure sale or a crystallization transaction while still resident.
• CFC status begins: Form 5471 annually (category rules, schedules, penalties starting at $10,000 per form per year); GILTI includes the company's tested income on the owner's 1040 currently — the retained-earnings deferral that made the corporation attractive in Canada does not survive US shareholding; section 962 and foreign tax credits manage, not erase, the cost.
• The shares met the departure tax: deemed disposition at fair market value (a real valuation), T1244 deferral with the shares as security is the norm, and the treaty basis election sets US cost at the departure value.
• Mind and management is now a live issue: directors, decisions, and the books should demonstrably remain in Canada if the company is to remain Canadian-resident; a company run from the owner's Miami desk invites a corporate residence and treaty analysis nobody ordered.
• Dividends after the move: 15% Canadian withholding under the treaty (5% for corporate shareholders at 10%+ voting — not the individual case), taxable in the US as dividends (qualified status per the treaty), with the withholding credited — the integrated Canadian rates are gone, and the surplus-stripping math changes accordingly.
• The realistic endgames: sell before departure (LCGE while it lives); wind up and distribute before departure (Canadian rates, clean slate); keep operating with full dual compliance (justified for real Canadian businesses with management genuinely in Canada); or reorganize — including US-entity continuance or asset migration — with professional design. Drifting across the border with the company unexamined is the one plan with no upside.

The pre-departure quarter

The sequence that preserves the most value: valuation first (it feeds everything); LCGE analysis — purification if the company holds excess passive assets, crystallization or sale if the exemption is claimable; surplus decision — retained earnings distributed as dividends at resident integrated rates versus carried into the 15%-withholding-plus-US-tax future; governance reset — Canadian directors, documented Canadian management, or the honest conclusion that the company should move or wind up; and the emigration filings with the deferral election. Every one of these is cheaper, and some are only possible, before the departure date.

Worked example

A Waterloo consultant moves to Tampa owning 100% of her CCPC: C$300,000 annual active income, C$600,000 retained surplus, shares worth C$1.5M against nominal cost, qualifying for the LCGE. Pre-departure execution: valuation commissioned; a crystallization transaction claims her available LCGE against the accrued gain while she is resident and the shares qualify — stepping up cost and sheltering roughly C$1M of gain from the departure tax; C$400,000 of surplus is paid out as dividends at Ontario integrated rates (cheaper than the future 15%-plus-US path for her bracket); her sister in Kitchener joins the board and management protocols keep mind-and-management in Ontario, because the firm's clients and staff are genuinely there. At departure: deemed disposition on the stepped-up shares yields a modest residual gain, deferred under T1244 with a share pledge; the US basis election adopts the departure value. After: the company files as a non-CCPC at general rates; her 1040 carries Form 5471 and a GILTI computation managed with the 962 election; and the structure persists because the business is real — the alternative she priced, winding up entirely, lost to the value of the ongoing Canadian practice. The item that made the whole quarter worth six figures: the LCGE claim that ceased to exist the day she left.

Practitioner note

The corporation is the asset that punishes unplanned departures hardest, because its best attributes — the small business rate, the exemption, the deferral — are all resident-only and all expire at the border. Our pre-departure corporate review runs one question through every line: what is only available before the date? The answers fund the valuation, the crystallization, and the surplus strip — and the clients who skip the review meet Form 5471 and GILTI with none of the offsetting wins banked.
