A Canadian estate plan built for Canadian heirs can be a trap for an American one, and the trap is in the shares. The estate freeze — the standard Canadian tool: the parent exchanges their common shares of the family company for fixed-value preferred shares (freezing the parent's value at today's fair market value), and new common shares are issued — at a nominal price — to the children directly or to a family trust, so future growth accrues to the next generation and the parent's deemed disposition at death (the inheritance guide) is limited to the frozen value; the freeze is tax-deferred in Canada (section 86 for an exchange of shares in a reorganization of capital, which is automatic, or section 85 for a transfer of the shares to the company or a holding company with a joint election on Form T2057). The U.S. child as a shareholder — the CFC question: a U.S. person who owns 10 percent or more of the company by vote or value is a U.S. shareholder of a foreign corporation; if U.S. shareholders (counting shares owned directly, through foreign entities and trusts, and constructively — family attribution under section 318(a)(1) reaches a spouse, children, grandchildren and parents but not siblings, and section 958(b)(1) blocks attribution from a nonresident-alien parent to a U.S. child) together own more than 50 percent, the company is a controlled foreign corporation — the U.S. child files Form 5471 and includes their share of subpart F and net CFC tested income (formerly GILTI) each year (the U.S. citizen owning a Canadian corporation guide); a single U.S. child with a minority interest among Canadian siblings may avoid CFC status (the U.S. shareholders' total 50 percent or less), but still files Form 5471, as a category 3 filer, for the year their holding reaches 10 percent — annual category 4 or 5 filings follow only if the company is a CFC. The PFIC question: a Canadian corporation whose assets or income are mostly passive (a holding company with an investment portfolio, a real estate holding company in some cases, a company that has sold its business and holds the proceeds) can be a passive foreign investment company for a U.S. shareholder who isn't covered by the CFC rules — the PFIC regime taxes distributions and gains under the excess distribution rules (an excess distribution or any gain is allocated ratably over the holding period, the amounts allocated to earlier PFIC years taxed at each year's highest ordinary rate plus an interest charge, and gains taxed as ordinary income rather than capital gain — section 1291) unless the shareholder makes a qualified electing fund election (requiring the company's annual PFIC statements under U.S. principles) or a mark-to-market election (only for marketable stock — not available for private company shares); so a U.S. child holding shares of a family holding company with a portfolio is likely a PFIC shareholder, filing Form 8621 each year, and the regime's cost on eventual distributions is severe; the CFC rules override PFIC for a U.S. shareholder of a CFC (the overlap rule of section 1297(d), which covers only a 10-percent U.S. shareholder while the company is a CFC — a smaller U.S. holder of the same company stays under the PFIC rules). The family trust — the foreign trust: when the freeze shares are issued to a Canadian family trust with a U.S. beneficiary, the trust is a foreign non-grantor trust for that beneficiary (the Canadian trust with U.S. beneficiaries guide) — the throwback rules on accumulated income, Form 3520 on distributions, and — through the trust — the beneficiary's indirect ownership of the company's shares for CFC and PFIC purposes (sections 958(a)(2) and 1298(a)(3) treat stock owned by a foreign trust as owned proportionately by its beneficiaries — for a discretionary trust, on all the facts and circumstances), so a U.S. beneficiary may have PFIC or CFC exposure through the trust even without receiving anything. The parent's death and the U.S. heir: when the parent dies, the Canadian deemed disposition taxes the frozen preferred shares' gain (the inheritance guide), and the shares pass by will — a U.S. heir inheriting shares of a Canadian corporation receives a U.S. basis equal to fair market value at death (section 1014 applies to property acquired by bequest whatever the decedent's citizenship or residence — Rev. Rul. 84-139 — and the PFIC rule that can reduce the step-up doesn't apply where the decedent was a nonresident alien throughout the holding period, section 1291(e)), files Form 3520 for bequests from a foreign estate totaling more than US$100,000 in the year, and becomes a shareholder with the CFC and PFIC questions going forward; the post-mortem pipeline, or a redemption within the graduated rate estate's first three taxation years (the first year only if the death was before August 12, 2024) with the resulting loss carried back under subsection 164(6), that Canadian estates use to avoid double tax on the corporation's surplus has to consider a U.S. heir's PFIC or CFC exposure on the transactions. Planning for the U.S. heir. Give the U.S. heir a different asset: the Canadian heirs take the company; the U.S. heir receives non-corporate assets of equal value (cash, Canadian real estate, life insurance proceeds — the parent's estate equalized with insurance owned outside the company), avoiding CFC and PFIC entirely. A separate U.S.-friendly structure: the U.S. heir's share of the freeze is issued to a U.S.-designed trust or held through a structure that avoids the PFIC regime (an active operating company isn't a PFIC so long as passive income stays under 75 percent and passive assets under 50 percent; a holding company with mostly passive assets is); the company's passive investments are moved out (or the U.S. heir's interest is in the operating company only, not the holding company). Elections and compliance: if a U.S. heir must hold shares of a PFIC, the company provides the annual information for a qualified electing fund election (the company's Canadian accountant computing its income under U.S. principles — an annual cost the family accepts), avoiding the excess distribution regime; for a CFC, the section 962 and high-tax elections (the U.S. citizen owning a Canadian corporation guide). The U.S. heir who will move back: a U.S. citizen child who will live in the United States permanently holds Canadian corporate shares for decades — the planning is for that duration; a child who is a U.S. resident only temporarily may resolve the issue by leaving. The bookkeeping: the family's ownership chart with each person's residency and citizenship; the company's asset and income mix (the PFIC tests of section 1297(a) — 75 percent or more passive income, or at least 50 percent passive assets by average value); the CFC ownership computation with attribution; the trust's U.S. beneficiaries; the U.S. heir's forms (5471, 8621, 3520); the estate equalization plan. The errors: an estate freeze implemented with new shares issued to a U.S.-citizen child (a CFC or PFIC shareholder from day one); the family holding company's portfolio never tested for PFIC; a U.S. beneficiary of the family trust unaware of the indirect ownership; Form 8621 never filed (an open statute and the excess distribution regime by default); and the will leaving the holding company's shares equally to all children including the U.S. one, without equalization.
Key takeaways
- An estate freeze that issues new common shares to a U.S. child makes that child a U.S. shareholder of a foreign corporation — Form 5471 at 10 percent or more, and CFC inclusions if U.S. shareholders together own more than 50 percent (constructive ownership counts, though a Canadian parent's shares aren't attributed to a U.S. child).
- A family holding company with mostly passive assets is likely a PFIC for a U.S. shareholder — Form 8621 every year, and the excess distribution regime's punitive tax and interest unless a qualified electing fund election is supported.
- A Canadian family trust is a foreign trust for its U.S. beneficiary — throwback, Form 3520, and indirect CFC or PFIC ownership through the trust.
- A U.S. heir inheriting Canadian shares gets a fair-market-value basis at death but inherits the CFC and PFIC questions going forward, and files Form 3520 for the inheritance.
- The cleanest plan gives the U.S. heir different assets — cash, real estate, insurance-funded equalization — and leaves the corporation to the Canadian heirs.
- Otherwise: an active operating company (not a PFIC), passive assets moved out, and the company's annual QEF or CFC information — a cost the family accepts knowingly.
The cross-border family succession file
Ownership chart with residency and citizenship. Company asset and income mix (PFIC tests). CFC computation with attribution. Family trust's U.S. beneficiaries. U.S. heir's forms: 5471, 8621, 3520. Estate equalization plan; insurance. The ownership chart is the document every Canadian freeze needs before the shares are issued.
Worked example
A Montreal family's operating company (manufacturing, an active business) and holding company (C$8 million of investments) are owned by the founder, 70; his three children: two in Montreal, one in New York (a U.S. citizen by marriage and naturalization). The family's Canadian advisers proposed a freeze issuing new common shares of the holding company to a family trust for all three children. The desks flagged it: the holding company is a PFIC for the New York child (its C$8 million of investments puts it over the 50 percent passive-asset test, and its dividends, interest and gains over the 75 percent income test), held indirectly through a foreign trust — Form 8621 and Form 3520 annually, the excess distribution regime on any distribution, and the throwback on accumulated trust income. The revised plan: the freeze's new shares of the operating company (an active business — not a PFIC) go to a trust for the two Canadian children only; the U.S. child is equalized with a life insurance policy owned by a separate structure outside the companies and a specific bequest of the founder's Montreal condominium and cash — so she inherits no Canadian corporate shares, files a Form 3520 for her inheritance, and receives a stepped-up U.S. basis in the condominium. A neighboring family that had frozen into a trust for all its children a decade earlier found its Boston beneficiary had a decade of unfiled PFIC and foreign trust forms to remediate.

Practitioner note
A Canadian estate freeze built for Canadian heirs lands on an American child as shares of a foreign corporation — a CFC if the U.S. shareholders control it, a PFIC if it's a holding company with a portfolio — often held through a family trust that is a foreign trust in its own right. Our desks draw the family's ownership chart with every member's residency and citizenship before the freeze shares are issued, test the companies for PFIC and CFC status, and usually steer the U.S. heir toward different assets — real estate, cash, insurance-funded equalization — so the next generation's succession doesn't arrive with a decade of Form 8621s and a throwback tax.
