U.S. Citizen Owning a Canadian Corporation: Form 5471, GILTI, Subpart F, and the Section 962 Election

A U.S. citizen in Canada running a Canadian corporation is doing the most ordinary thing a Canadian business owner does, and the IRS sees a controlled foreign corporation. The controlled foreign corporation: a foreign corporation more than 50 percent owned (by vote or value) by U.S. shareholders — U.S. persons owning 10 percent or more — is a CFC; a U.S. citizen who owns their Canadian corporation outright owns a CFC, and so does a U.S. citizen who owns 60 percent with a Canadian spouse owning 40 (the 60 percent alone exceeds 50 percent; a nonresident-alien spouse's shares are not attributed to the U.S. citizen — section 958(b)(1) — so a 50/50 split would not make it a CFC). Form 5471 — every year: the U.S. shareholder of a CFC files Form 5471 with the U.S. return — the corporation's income statement and balance sheet in U.S. dollars and under U.S. tax principles, the shareholder's share of its income, its transactions with related parties, its earnings and profits and previously taxed earnings accounts — with a US$10,000 penalty per form per year for failure to file (the IRS's form page), and the statute of limitations on the entire U.S. return stays open until the form is filed (only the related items, if the failure was due to reasonable cause — section 6501(c)(8)); the form is long, and the Canadian corporation's financial statements are the starting point, converted to U.S. principles. Subpart F — the passive income: the CFC's foreign personal holding company income (interest, dividends, rents and royalties not from an active business, capital gains on investments) is included in the U.S. shareholder's income currently, whether or not distributed; a Canadian corporation that retains its after-tax profits in an investment portfolio inside the company (the common Canadian practice — the corporation as a holding tank taxed at the small business rate) generates subpart F income from that portfolio; the high-tax exception excludes subpart F income taxed in Canada at more than 90 percent of the U.S. corporate rate (18.9 percent) — Canadian passive investment income in a CCPC is taxed at high rates (about 47 to 55 percent depending on the province, of which 30⅔ percentage points is refundable when taxable dividends are paid — the refundable dividend tax on hand mechanism; a refund reduces the foreign tax counted for the high-tax test, and the rate net of the refund can fall near or below 18.9 percent). GILTI — the active profits: the CFC's active business income that isn't subpart F is tested income for the global intangible low-taxed income regime (renamed "net CFC tested income" by P.L. 119-21 for CFC tax years beginning after 2025, which also eliminated the 10 percent deemed return on tangible assets that used to shelter part of the income) — the U.S. shareholder includes it currently; a Canadian CCPC's active income taxed at the small business rate (9 percent federal plus 0 to 3.2 percent provincial — about 9 to 12 percent combined — on the first C$500,000 of active business income) is low-taxed income from the U.S. perspective, so the GILTI inclusion produces U.S. tax that the Canadian tax only partly offsets; an individual U.S. shareholder can't claim a foreign tax credit for the corporation's Canadian tax against GILTI unless they make the section 962 election, and doesn't get the section 250 deduction either — so without planning, the U.S. citizen owes U.S. tax at individual rates on the CFC's active income each year, and then Canadian tax on the dividends when the company pays them — a double tax. The high-tax exclusion election: GILTI's high-tax exclusion (an election excluding tested income taxed at more than 90 percent of the U.S. corporate rate — 18.9 percent) excludes the income of a CCPC whose active income is taxed at the general rate (about 23 to 31 percent — 23 in Alberta, 26.5 to 27 in Ontario and British Columbia) — but not the small business rate's income, which is below the threshold; so one planning lever is to forgo the small business deduction (paying the general rate in Canada — or earning above the small business limit) to exceed the threshold and exclude the income from GILTI — a trade of Canadian tax for U.S. tax that the desks model. The section 962 election: an individual U.S. shareholder may elect to be taxed on the CFC inclusions (subpart F and GILTI) as if a domestic corporation — at the corporate rate (21 percent), with the section 250 deduction for GILTI (40 percent for tax years beginning after 2025 — an effective 12.6 percent rate) and the indirect foreign tax credit for the Canadian corporate tax (90 percent of it for net CFC tested income from 2026, up from 80 percent — the IRC 960 guide) — often reducing the current U.S. tax on the inclusions to near zero for a CCPC paying the general rate, and to a modest amount for one at the small business rate; the cost: when the Canadian corporation later pays a dividend, the previously taxed earnings are taxable again to the extent they exceed the U.S. tax paid under the election (section 962(d)), though the dividend from a Canadian corporation may be a qualified dividend (the treaty country rule — the dividend tax credit guide's U.S. side) taxed at the lower rate, with a foreign tax credit for Canadian tax on the dividend; the election is made annually. Salary instead of retained earnings: a U.S. citizen owner can reduce the CFC's income by paying themselves a salary (deductible to the corporation in Canada; taxable to the owner in both countries as wages — with the U.S. foreign earned income exclusion (US$132,900 for 2026) or the foreign tax credit for Canadian tax on the wages) — the simplest way to keep income out of the GILTI and subpart F computations, at the cost of the Canadian tax deferral the small business rate offers; many U.S.-citizen owners of CCPCs pay out their profits as salary or dividends each year rather than retaining them, to avoid the U.S. inclusion regime entirely. The Canadian side: the CCPC's small business deduction, the refundable taxes on investment income, the dividend tax credit on dividends paid — all unchanged by the owner's U.S. citizenship; the owner's T1 reports the salary and dividends; the U.S. return is where the complexity lives. The other forms: the FBAR for the corporation's accounts (an owner of more than 50 percent has a financial interest in them, and signature authority alone is also reportable), Form 8938 for the shares (satisfied by the timely Form 5471, though their value counts toward the 8938 threshold), Form 8992 for the inclusion (retitled for net CFC tested income from 2026), Form 8993 for the section 250 deduction under the election, Form 1118 or 1116 for the credits under the election. The bookkeeping: the Canadian financial statements converted to U.S. principles and dollars; the CFC's income classified (subpart F, tested income, high-taxed); the section 962 analysis each year; the previously taxed earnings accounts; the owner's salary and dividend plan; the forms (5471, 8992, 1118 or 1116, FBAR, 8938). The errors: Form 5471 never filed (US$10,000 per year per form and an open statute on the whole return); the corporation's investment portfolio's income never reported as subpart F; GILTI ignored; the section 962 election never considered; and the owner's compensation plan set without the U.S. side in view.

Key takeaways

• A U.S. citizen's Canadian corporation is a controlled foreign corporation — Form 5471 every year, with a US$10,000 penalty per form and the whole U.S. return's statute of limitations held open until it's filed.
• Subpart F taxes the CFC's passive income currently — the investment portfolio held inside a CCPC — subject to the high-tax exception.
• GILTI (as modified by the 2025 legislation) taxes the CFC's low-taxed active income currently — a CCPC's small-business-rate income is low-taxed; income taxed at the general rate may be excluded by the high-tax election.
• The section 962 election taxes the inclusions as if the owner were a corporation — 21 percent, the section 250 deduction, and the indirect credit for Canadian corporate tax — often reducing the current U.S. tax sharply, at the cost of a second U.S. tax on later dividends.
• Paying out profits as salary or dividends each year keeps them out of the inclusion regime — the simplest plan, giving up the Canadian deferral.
• The Canadian side is unchanged; the complexity lives on the U.S. return.

The U.S. citizen's CFC file

Ownership and CFC status (attribution checked). Form 5471 (and the delinquency relief if missed). Financial statements converted to U.S. principles and dollars. Income classified: subpart F, tested income, high-taxed. High-tax elections; section 962 analysis; Form 8992; Form 1118 or 1116. Previously taxed earnings. Compensation plan: salary, dividends, retention. FBAR and Form 8938. The compensation plan is the lever; the 5471 is the obligation.

Worked example

A U.S. citizen living in Calgary owns 100 percent of an Alberta engineering consulting CCPC earning C$400,000 of active income taxed at the small business rate (about 11 percent), with C$1.2 million of retained earnings invested in a portfolio earning C$60,000 a year. Her U.S. side had never included the corporation: no Form 5471 for six years. Because the missing forms come with unreported subpart F and GILTI inclusions, the desks bring her current under the IRS's Streamlined Foreign Offshore Procedures — three years of amended returns with the Forms 5471 attached and six years of FBARs, with no penalties for a non-willful U.S. citizen living abroad (the delinquent information return procedure offers no automatic penalty relief and suits filers with no tax to report) — then plan: the portfolio's C$60,000 is subpart F income (taxed in Canada at a high rate, partly refundable — the high-tax exception analyzed); the C$400,000 of active income is tested income — low-taxed at the small business rate. Option one: pay a C$300,000 salary (deductible in Canada; taxable in both countries, with the foreign tax credit for Canadian tax on the wages covering most of the U.S. tax) — leaving C$100,000 of active income. Option two: retain the income and make the section 962 election — U.S. corporate-rate tax on the GILTI inclusion after the section 250 deduction, reduced by 90 percent of the Canadian corporate tax (a small residual U.S. tax at the small business rate), with a second U.S. tax when dividends are later paid. The desks model both over ten years with her retirement plans; she chooses a combination — a salary that uses her Canadian RRSP room and covers her living costs, the section 962 election on the remainder, and a plan to wind down the portfolio's passive income into an RRSP and a TFSA-alternative (the TFSA is a problem for a U.S. citizen — the TFSA vs Roth guide).

Practitioner note

A U.S. citizen running an ordinary Canadian corporation owns a controlled foreign corporation in the IRS's eyes — Form 5471 every year, subpart F on the investment portfolio the company holds, and GILTI on the small-business-rate profits the company retains — and without planning, the U.S. taxes those profits at individual rates now and Canada taxes the dividends later. Our desks file the delinquent 5471s under the IRS's relief procedures, then model the compensation plan, the high-tax exclusion, and the section 962 election over ten years together — because the Canadian side doesn't change, and the right answer is the one that uses both returns.
