Three Families, One Question
Sarah’s spouse helps with the bookkeeping about ten hours a week. David’s adult son works full-time on the warehouse floor of the family’s contracting business. The Khanna family completed an estate freeze a few years ago and now distributes through a discretionary trust to three grown children. Three different households, three different corporations — and one question sitting underneath all of them: can we move some of this income onto a family member’s tax return instead of mine, and have it actually stick?
Each of these families is trying to do the same thing — share income across the household so the same corporate dollar is taxed in a lower hand instead of the owner’s top bracket. TOSI — the Tax on Split Income rules — is what decides whether that works. It is not a ban on paying your family. It is a set of gates. Walk a family member through the right gate and the dividend lands at their normal rate. Miss every gate and the same dividend is re-priced at the top marginal rate, as if it had never left your hands. In what follows I walk through what’s actually possible for each of these three families, and what the structure costs to make it work.
This is the planning conversation — the one that should happen long before any dividend is declared. For a Canadian incorporated owner, TOSI is the rule that shapes family compensation more than any other, because it decides how your share structure, your family’s real involvement in the business, and your trust (if you have one) line up against those gates. Get the design right and the year-end distribution becomes a short, calm call with your accountant. Get it wrong and no amount of December cleverness will rescue it.
One piece of history matters, because it changed who this affects. Until 2018 these rules were a narrow “kiddie tax” aimed only at distributions to minor children. The 2018 reform tore the age cap off, and since then — still in 2026 — TOSI reaches any adult family member: your spouse, your adult kids, your parents, your siblings. That single change is why income-splitting stopped being a default you could assume and became a design problem you have to solve on purpose.
Key Takeaways
- Lead with the decision, not the rule. TOSI decides whether a dividend to a family member is taxed at their rate or re-priced to the top bracket — roughly 48% on ordinary income and 42.31% on a non-eligible dividend in Alberta in 2026. The planning job, before year-end, is to make sure each family member fits cleanly through one of five gates.
- Salary and dividends are not the same animal here. A reasonable salary for genuine work paid to your spouse or child sidesteps TOSI entirely; a dividend has to qualify for an exclusion. That is why the salary-vs-dividends decision and TOSI are really one decision.
- Five gates, read as planning tests: Can the family member actually do the work (Excluded Business)? Can we structure real ownership (Excluded Shares)? Can we document genuine capital or risk (Reasonable Return)? Is the owner 65+ (Spouse 65+)? Did the shares come by inheritance (Inherited Property)?
- The family trust is the dominant fact pattern. After an estate freeze, every annual distribution becomes a per-beneficiary TOSI decision — which is where most of the planning value, and most of the risk, lives.
- Design years ahead, not in December. The share structure, the documentation habit, and the beneficiary plan all have to exist before the distribution. That structural design is my work. The year-end inclusion math and the filing are your CPA’s.

What I Do, What Your CPA Does
What I do, what your CPA does
This post is the planning conversation; the year-end execution is your CPA’s. My role is the structural design — which family members can legitimately receive distributions, what share structure supports it, when a family trust adds value, and how to fold the TOSI exclusions into a multi-year compensation plan. Your CPA owns the execution — the per-beneficiary TOSI inclusion calculation, the T1 reporting, the documentation file if CRA reviews. I don’t compute the inclusion and I don’t sit between you and the CRA.
How TOSI Decides Who Pays the Top Bracket
Before the scenarios, the mechanism — in plain terms, because you only need three things to follow the rest of this post.
Who the rules treat as “family”
TOSI only fires when two people are related and one of them is the reason the business makes money. The rules give these two people technical names, but strip the jargon away and the test is simply this: is the person receiving this dividend related to me, resident in Canada, and getting it because of my business? You are the one whose work and capital drive the company; the family member is the one receiving the income. If they’re related to you, in Canada, and the money traces back to your business, TOSI is in the room — not necessarily biting, but in the room — and the only thing that gets the income out at a normal rate is one of the five exclusions. If the recipient is unrelated to you, or the income has nothing to do with a family business, TOSI never enters the conversation at all. The whole regime is a family-relationship rule first and a tax rule second.
What kind of income it catches
Not everything is exposed. TOSI reaches into dividends and shareholder benefits from your private corporation, income flowed out to a beneficiary from a family trust that holds your shares, certain partnership income from the family business, and — the one people forget — certain capital gains on the sale of private-company shares. That last item matters because it means TOSI can surface in the year you sell, not just in the quiet dividend years, which is exactly where it collides with the lifetime-capital-gains-exemption planning in the capital gains post. What it does not touch is a reasonable salary for real work. Salary for genuine work is simply wages — outside these rules entirely. That single distinction is the most useful planning lever you have, and it’s why the first scenario turns on it.
What it costs if it bites
If none of the gates open, the income is taxed at the top combined marginal rate — full stop, regardless of how little the family member otherwise earns. In Alberta in 2026 that’s roughly 48% on ordinary income and about 42.31% on a non-eligible dividend. Put numbers on it: a $50,000 dividend you hoped to land on a spouse in a 25% bracket — about $12,500 of personal tax — gets re-priced to roughly $21,000 if TOSI applies. The graduated brackets vanish; the personal credits mostly don’t help. The entire point of the planning is to never be in that position by accident — to know, before the dividend is declared, which gate each person walks through.
Scenario 1: Sarah — A Spouse Working Part-Time
The setup. Sarah is married to Michael, who owns a Calgary marketing-services corporation. She does the books, vendor coordination, and invoicing — ten to twelve hours in a typical week. Michael’s accountant has floated a $40,000 year-end dividend to shift income onto her lower-taxed return. His question to me was simple: “Can we just pay her a dividend? She does real work.”
Which gates are in play. Only two are worth Sarah’s time. She owns no shares (ownership gate out), Michael is 48 (over-65 gate out), inheritance is irrelevant. The work gate (Excluded Business) has a bright line — average 20+ hours a week and the dividend escapes TOSI automatically. At ten to twelve hours she’s under it, and below the line it becomes a question of fact you have to argue, which a family with no time record usually loses. The contribution gate (Reasonable Return) could support a modest amount, but only with documentation — and right now the file is empty.
What I’d recommend. Not the dividend — a salary. Salary for genuine work isn’t split income at all, so it sidesteps TOSI entirely; it just has to be reasonable for her actual hours and run through payroll with a simple contemporaneous record. There’s a household-plan bonus the dividend can’t match: salary builds RRSP room and CPP for Sarah, giving her an independent retirement base rather than dependence on Michael’s. This is why salary-versus-dividend planning and TOSI are one decision — dividend-splitting with a part-time spouse runs into the rules; salary-splitting for the same work walks around them. If the goal is specifically dividends at her rate, the real project is getting her over the 20-hour line and documenting it — which happens now, by changing how the work is structured, not in December.
Scenario 2: David — An Adult Child Working Full-Time
The setup. David is 28 and has worked full-time in his mother Jennifer’s Calgary mechanical-contracting company since 2022 — roughly 50 hours a week running projects, on a $95,000 salary plus bonus. Jennifer wants to give him a real ownership stake — 15% of the common shares — and pay a $30,000 annual dividend on top of his pay. Partly tax planning; mostly succession.
Which gates are in play. David is the easy case — the mirror image of Sarah — with two gates wide open. The work gate isn’t close: at 50 hours a week for years, his dividends are TOSI-exempt on his work alone, on nothing more than existing payroll records. And once someone clears the 20-hour bar for any five years the exemption sticks for life even if they later dial back, so by 2027 David has it permanently. The ownership gate (Excluded Shares) opens too once the shares are issued: a family member 25+ holding 10%+ of votes and value, in a business that isn’t a professional practice or mostly service revenue. David’s 15% clears it, and a contracting firm that bills materials and equipment is exactly the operating business this gate was built for — subject to confirming the revenue mix.
What I’d recommend. Issue the shares — but for the succession reason first, tax second. His dividend is already safe under the work gate; ownership gives him a second, independent route, so the structure still holds if his hours ever drop. Pair it with the conversation Jennifer hasn’t had: what happens to her own holding, whether this is the first tranche of a larger estate freeze, and how any siblings are treated. A 15% issuance reshapes the cap table and the eventual estate — design it as one move, not a bolt-on for a $30,000 dividend. How she hands over the shares (direct issuance, freeze, or section 85 rollover) is a design decision for her accountant and a tax lawyer; my role is framing which structure fits the succession goal and her retirement plan.
Scenario 3: The Khanna Family Trust After an Estate Freeze
The setup. The Khanna family — from the estate-freeze playbook — froze the company a few years ago, and growth now accrues to a discretionary family trust with real income to distribute, say $90,000 a year. Around the table: Rajesh (56, the owner whose work built the company), his wife Priya (56, not active in the business), daughter Anaya (31, full-time in the business), and son Vikram (28, a developer at an unrelated tech company). The trustees can sprinkle the $90,000 however they choose; TOSI decides what each choice costs. This is the fact pattern that matters most — a discretionary trust looks like total flexibility, and TOSI is what turns “distribute however you like” into “distribute however each beneficiary’s gate allows.”
Gate by gate. Rajesh is the source, not a recipient — TOSI doesn’t apply, but his rate is the family’s highest, so distributing to him “to be safe” defeats the trust’s purpose. Anaya walks through the work gate cleanly: full-time, well past 20 hours, TOSI-free at her own rate — the trust’s most efficient destination. Priya is the hard case: no work, no personal share ownership, and a decade from the over-65 gate, so her only door is Reasonable Return — open only because she personally guaranteed the company’s credit line. That’s genuine risk, and with documentation the trustees can defend a modest allocation sized to the guarantee, not an unlimited one. Vikram has no gate at all — any dividend to him is taxed at the top rate, no better than distributing to Rajesh and worse than leaving it with Anaya.
What I’d recommend. Allocate to Anaya first, to Rajesh only where it still beats the alternatives, and to Priya only what her guarantee supports — with the documentation built now, not at year-end. For Vikram, a small or zero allocation, plus the live planning question: what would change his answer? If he joined the business or made a documented capital contribution, a gate opens. The freeze and trust already did the heavy lifting — multiplying the lifetime capital gains exemption across the family for the eventual sale — but the annual distribution is a live decision each year, beneficiary by beneficiary, against gates that shift as people age, change jobs, or take on risk. My role is keeping that beneficiary map current; the accountant computes each inclusion and files.
The Five Exclusions at a Glance
The same five gates, as a planning map. Read down the last column and you have the failure list — which is the next section.
| Gate | Who it’s for | The planning test | The documentation cost | Where it breaks |
|---|---|---|---|---|
| Excluded Business | A spouse or child who actually works in the business | Do they average 20+ hours/week — or did they for any 5 prior years? | Time records, payroll, a written job description, kept as you go | Part-timers under 20 hours with no contemporaneous log |
| Excluded Shares | An adult (25+) you want to give a real ownership stake | Do they hold 10%+ of votes AND 10%+ of value of a non-professional, non-service company? | Share register, minute book, prior-year financials showing the revenue mix | Professional corps and mostly-service businesses — the gate is simply closed to them |
| Reasonable Return | A family member who contributed capital or carried risk, not just labour | Is the amount reasonable for what they actually put in or risked? | Loan agreements, guarantee documents, a contemporaneous reasonableness memo | After-the-fact stories with no paper — the most-reviewed, least-defensible gate |
| Spouse 65+ | A near-retired or retired owner and their spouse | Is the owner 65+ at any point in the year? | Date of birth and proof of the relationship — that’s all | Nothing, once the owner hits 65 — but useless before then |
| Inherited Property | An heir who received company shares on a death | Did the shares come by inheritance? | Will, estate paperwork, beneficiary designation | Rarely — but the planning lives in the estate documents, not the dividend |
The Three Planning Failures I See Most
If you came here looking for a year-end TOSI compliance checklist — the line-by-line, declare-the-dividend-in-December workflow — that’s your accountant’s deliverable, and rightly so. What follows is the opposite: the planning work that should happen long before that conversation, framed as the three mistakes I’m most often called in to unwind.
Failure 1: Designing the compensation plan first and remembering TOSI in December. The family sets up who gets paid what — a dividend to the spouse, a sprinkle to the kids — and only at year-end asks whether it survives TOSI. By then the share structure is fixed and the work has either been done or not; the only move left is “can we re-characterize this as something else?” That’s not planning, it’s damage control. The fix is to run the gates before the structure is built, which is the entire premise of this post.
Failure 2: Assuming the ownership gate works for a professional or service corporation. I see doctors, consultants, and IT-services owners issue shares to a spouse or adult child expecting the Excluded Shares route to carry the dividends — and it doesn’t, because that gate is closed to professional corporations and to businesses that are mostly service revenue. Those families have to live on the work gate or Reasonable Return instead, and they usually discover the mismatch too late to fix it for the year. If your revenue is mostly your time, assume the ownership gate is shut and plan around it from the start.
Failure 3: Leaning on Reasonable Return with nothing in the file. Reasonable Return is the most flexible gate and the most dangerous, because families treat “reasonable” as something they can explain later. On review, an undocumented contribution is no contribution. If the plan rests on capital someone put in or risk they carry, the loan agreement, the guarantee, and a short reasonableness note have to exist now — contemporaneously — or the gate effectively isn’t there when you reach for it.

The statutory references behind the gates above live here rather than in the body, so the planning reads cleanly. TOSI is in section 120.4 of the Income Tax Act; the Excluded Business 20-hour rule is paragraph 120.4(1.1)(a); the Reasonable Return test is paragraph 120.4(1.1)(g); “split income” is defined in subsection 120.4(1).

Frequently Asked Questions
Can I pay my spouse dividends from our CCPC without triggering TOSI?
Yes — but only if your spouse fits through one of the gates, and simply owning shares is not one of them. The realistic paths are: the work gate (your spouse genuinely averages 20+ hours a week in the business, or did for any five prior years); the ownership gate (they directly hold 10%+ of votes and value in a non-professional, non-service company); Reasonable Return (their dividend reflects documented capital they contributed or risk they carry, such as a personal guarantee); or the Spouse 65+ gate once you’re 65. Here’s the planner’s read, though: if your spouse does real but part-time work, a reasonable salary is almost always the cleaner answer than a dividend, because salary for genuine work isn’t split income at all. The salary-vs-dividends decision and TOSI are the same decision for a family member.
My adult child works in the business — when do their dividends escape TOSI?
The moment they’re genuinely full-time. A family member who averages 20+ hours a week clears the work-gate safe harbour, and their dividends are TOSI-free on that basis alone — documented with the payroll records you already keep. Better still, once they’ve cleared that bar for any five years, the exemption sticks for life even if they later cut back. If you also give them a real ownership stake — 10%+ of votes and value in a non-professional, non-service corporation — they pick up a second, independent gate, which is worth doing when share ownership also serves your succession plan. Full-time kids are the easy case; the planning is mostly about pairing the dividend with a deliberate ownership and succession design rather than bolting it on.
Does TOSI apply to distributions from our family trust after the estate freeze?
Yes — and this is where TOSI matters most. After a freeze, every annual trust distribution is a per-beneficiary TOSI decision: each person needs their own open gate, and the gates differ across the family. An adult child working full-time in the business is clean; a non-working spouse under 65 usually needs a documented Reasonable Return case (for example, a personal guarantee on the company’s credit line); a beneficiary with no work, no direct ownership, and no contribution takes the full top-rate hit on anything sprinkled to them. The trust gives the trustees discretion; TOSI prices each choice. The practical work is keeping a current beneficiary-by-beneficiary map so the allocation each year goes where a gate is actually open.
What’s the difference between what my CPA does on TOSI and what my financial planner does?
Your CPA owns the year-end execution: computing each beneficiary’s TOSI inclusion, filing the T1s, and assembling the documentation file if CRA reviews. I own the structural design that happens long before any of that — which family members can legitimately receive distributions, what share structure and trust design support it, and how the whole thing folds into your multi-year compensation and estate plan. Put simply, your CPA answers “what’s the number this year and is it filed correctly”; I answer “how should this family be structured so the number is low and defensible every year.” Both roles are necessary, and the structure only works when the planning and the execution are done by people who each know their lane.

Conclusion
TOSI isn’t a wall; it’s a set of gates, and the game is knowing which one each family member walks through before you declare a dollar. Sarah’s answer was a salary; David’s, a share issuance that doubled as succession; the Khannas’, a different call for each of four people, revisited yearly. None came from a December scramble — they came from designing the structure with the gates in mind. That design is my work; the year-end math is your accountant’s. Not sure which gate your family walks through? That’s the conversation to have now.

Important disclosure
General information only — not personalized investment, tax, or legal advice. Tax rules change frequently and your situation may differ materially from the scenarios above, which use composite names and facts. The TOSI rules in section 120.4 turn on the specific facts of each family member’s involvement in the business, and each gate has to be re-tested every year for each person — a result that worked one year may not hold the next if the facts change. The year-end inclusion calculation and filing are properly the work of a qualified Canadian CPA who has the full picture of the corporation’s financials, the trust’s prior distributions, and each beneficiary’s circumstances. This post is the financial-planning overview, not a substitute for that accounting work. Consult a qualified Canadian CFP and CPA before acting on anything here.
