Salary vs Dividends for a US Citizen Who Owns a Canadian Corporation: GILTI Rewrote the Answer

Short version: Qualified Dividends From Canadian Companies Explained

Canadian owner-manager compensation planning is a domestic art built on integration: salary is deductible to the corporation and taxed personally; dividends come from after-corporate-tax profit with a credit that roughly squares the total; the mix optimizes RRSP room, payroll costs, income smoothing, and the small business deduction. A US-citizen owner imports a second system that refuses to integrate. The structural fact: the CCPC is a controlled foreign corporation, and GILTI sweeps most of its active business income onto the owner's 1040 as earned by the corporation — the retained-earnings deferral that anchors Canadian planning simply doesn't exist for the American owner, who is taxed personally, currently, on profits left in the company. The consequences cascade through the compensation choice. Salary: deductible in Canada (reducing the very income GILTI would sweep), taxed to the owner in Canada at full rates, fully creditable against the US tax on the same wages — the clean channel, where high Canadian tax does double duty and the US result is typically zero; salary also manufactures RRSP room, the American owner's best remaining shelter. Dividends: paid from income that already ran the GILTI gauntlet (or the Canadian corporate tax, or both), taxed in Canada with the dividend credit and in the US as dividend income — where the previously-taxed-income tracking, the qualified-dividend question, and the credit mechanics between four tax pools (Canadian corporate, Canadian personal, US GILTI-layer, US dividend-layer) demand genuinely professional bookkeeping and still leak in common configurations. The management tools on the US side — the section 962 election (taxing GILTI at corporate rates with a foreign tax credit for the CCPC's Canadian corporate tax, usually crushing the GILTI cash tax where Canadian rates apply, at the price of a second tax when the earnings later distribute) and the high-tax exclusion where rates and computations qualify — convert GILTI from a catastrophe to a managed annual computation, but they are mitigations inside a system that still rewards one strategy above the elections: leave less in the corporation. The resulting playbook: salary to the owner sized to needs, RRSP room, and profit reduction; the small business deduction's value re-weighed honestly (deferral is worth little to someone taxed currently anyway — the American owner often optimizes toward less retained income, not the C$500,000 of it); dividends used deliberately and tracked through the pools rather than defaulted to; TOSI respected on any family-member dividends exactly as domestic planning requires; and the perennial alternatives — unincorporated practice, or a structure where the non-US spouse holds what an American shouldn't — priced at every annual review, because for many US-citizen professionals the corporation's surviving benefits no longer cover its 5471-and-GILTI rent.

Key takeaways

• The deferral is gone: GILTI taxes the CCPC's active income to the US owner as earned — retained earnings are not a shelter for an American, and every Canadian planning instinct built on deferral needs re-derivation.
• Salary is the mismatch-free channel: Canadian-deductible (shrinking GILTI's base), Canadian-taxed, US-credited — near-zero US cash tax, RRSP room generated, payroll mechanics the only cost. The American owner's default should tilt salary-heavy relative to domestic practice.
• Dividends are trackable, not terrible: after 962 elections and PTI accounting they can emerge sensibly — but they demand pool-by-pool tracking across years and preparers, and undocumented dividend habits are where the double tax actually lands.
• The 962 election and high-tax analysis are annual, not permanent: run the computation each year with the CCPC's actual Canadian tax rate (the small business deduction's low rate can be the thing that makes GILTI expensive — another reason the SBD's value inverts for American owners).
• Form 5471 is the rent: category rules, schedules, and $10,000-per-form starting penalties make the compliance floor real regardless of elections — the corporation must earn its keep over unincorporated practice by more than the 5471's annual cost.
• Structure alternatives stay on the table: the non-US spouse as shareholder (with TOSI and attribution respected), the unincorporated professional, or the leaner corporation paying nearly everything out — each honest review asks whether this owner should have this corporation at all.

The annual computation, in order

Project the year: corporate income before owner compensation. Set salary: needs, RRSP target, and the GILTI-base reduction it buys. Compute the GILTI layer on what remains: with and without 962, with the high-tax analysis, at the corporation's actual blended rate. Decide the dividend, if any, against the pools: what's previously taxed, what the Canadian credit does, what the US layer adds. File the set — T2, T4, 5471, the elections — from one workpaper both preparers share. The owners who suffer are never the ones running this loop; they're the ones whose Canadian accountant optimized integration while their US preparer discovered the corporation in March.

Worked example

A dual-citizen dentist in Ottawa nets C$400,000 in her professional corporation before her own pay. Domestic-instinct plan: C$120,000 salary, the rest retained at the small business rate, dividends as needed — the deferral play. Her actual plan: C$260,000 salary (needs plus maximum RRSP room plus GILTI-base reduction), leaving C$140,000 of corporate income; the GILTI computation on it runs with a 962 election — the CCPC's Ontario small-business-rate tax gives a modest credit, the high-tax exclusion fails at that rate, and the 962 route prices the US layer at a manageable four figures; she pays a C$40,000 dividend for a renovation, tracked against the previously-taxed pool so its US treatment is a bookkeeping exercise rather than a second tax; her T2, T4, 1040, 5471, and election statements reconcile from one shared workpaper. Annual all-in cost of being American with a corporation: roughly C$6,000 of US tax and cross-border preparation. The review's standing question gets asked and answered: unincorporated, she'd save the compliance but lose the liability shell, the income-smoothing, and the modest surviving deferral — the corporation stays, one year at a time, on arithmetic instead of habit. Her associate — same clinic, same income, no US passport — runs the classic integration plan untouched, which is exactly the point: the passport, not the practice, picks the playbook.

Practitioner note

Owner-manager planning splits into two professions the day the owner files a 1040: the Canadian integration math still runs, but GILTI sits on top re-pricing every retained dollar, and the answer tilts salary-heavy, corporation-lean, elections-annual. Our rule for American owner-managers is one workpaper, two preparers, zero surprises — and one honest question asked every year, which is whether the corporation still earns its 5471.
