# TOSI, the tax on split income: paying dividends to family members


By EverStone CPA · Updated September 2026 · 7 min read







**Quick answer:** The tax on split income (TOSI) rules tax dividends paid to family members at the top personal rate unless a specific exception applies. Common exceptions involve a family member who works an average of at least 20 hours a week in the business, shareholders age 25 or older holding “excluded shares,” and certain retirement or inherited-property situations. Simply adding a spouse or adult child as a shareholder no longer guarantees safe income splitting.


Top rate by default — exceptions are narrow.

## Key takeaways

- TOSI taxes split income paid to family members at the top personal rate, not graduated rates.
- It generally applies to dividends (and some other amounts) paid by a private corporation to a related individual.
- The main exceptions involve genuine work in the business, age combined with “excluded shares,” and retirement or inherited-property situations.
- “Excluded shares” generally require the family member to be 25 or older and meaningfully connected to the business, not just related to the owner.
- Adding a spouse or adult child as a shareholder no longer automatically achieves income splitting.


For years, paying dividends to a lower-income spouse or adult child was one of the simplest tax moves available to an incorporated business owner. That changed. The tax on split income — TOSI — rules were expanded significantly in 2018, and they turned income splitting from a formality into something that has to be earned and documented. If you’re paying, or thinking about paying, dividends to family members who are shareholders, understanding TOSI isn’t optional.



## What the tax on split income actually does


TOSI exists to stop “income sprinkling” — routing dividends or other income to family members in lower tax brackets purely to reduce the family’s overall tax bill, regardless of what those family members actually contributed. Where TOSI applies, the split income is taxed at the **top personal marginal rate**, which typically eliminates the benefit of paying it to someone in a lower bracket in the first place. TOSI doesn’t ban paying dividends to family members — it just removes the tax advantage unless you can point to a recognized exception.

## Who TOSI can reach


TOSI generally applies to dividends and certain other amounts received by an individual from a private corporation that’s connected to a family member, a spouse or common-law partner, a child, or other related individuals — who is or was actively involved in that business. It doesn’t matter that the payment is legally structured as a dividend on shares the family member owns; if the underlying relationship and involvement don’t meet an exception, TOSI can still apply.


**The default assumption changed.** Before 2018, the starting assumption for many advisors was that dividends to adult family shareholders were fine. Today the safer starting assumption is the opposite: split income is taxed at the top rate *unless* you can affirmatively show an exception applies.

## The main exceptions, in plain language


TOSI includes several carve-outs. None of them are automatic — each has to be met and, ideally, documented as the year goes.




- **Excluded business.** If the family member is actively engaged in the business on a regular, continuous and substantial basis — generally understood as averaging at least 20 hours a week during the year, or having done so in any five earlier years that don’t need to be consecutive — dividends to them can be excluded from TOSI.

- **Excluded shares.** Available generally to shareholders who are 25 or older, hold a meaningful, direct equity stake, and meet specific tests around the type of income the corporation earns. This exception looks at the shares themselves rather than hours worked.

- **Reasonable return.** For some family members, particularly those in their late teens or twenties who don’t clearly meet the excluded-business or excluded-shares tests, a facts-based “reasonable return” analysis looks at what they actually contributed — labour, capital, or risk — relative to what they received.

- **Retirement.** Dividends to the spouse of someone who was actively engaged in the business before reaching a certain retirement age can, in some circumstances, remain excluded from TOSI.

- **Inherited property.** Shares received as a result of someone’s death can sometimes retain their excluded status in the hands of the person who inherited them.


Every one of these exceptions is fact-driven. None of them is satisfied just by the corporate registry listing a family member as a shareholder.



## Why “just put my spouse on the shares” isn’t safe advice anymore


Before TOSI was broadened, the mechanics of income splitting were mostly about share structure: issue the right class of shares to the right family member, and dividends could flow at their lower rate. That’s no longer sufficient. Now the corporation, and the family member receiving the dividend, need to be able to show — if CRA asks, which exception applies and why. A spouse who does the books for two hours a week, or an adult child whose name is on the share register but who has never worked in the business, is exactly the profile TOSI was designed to catch.



## Documentation matters as much as the plan


Because these exceptions turn on facts — hours worked, role, capital contributed, timing of involvement — the paperwork you’d want in an audit is the same paperwork that should exist from day one. That means timesheets or a record of hours, a description of the family member’s role, meeting minutes if capital or shares changed hands, and clarity on how compensation was decided. Waiting until CRA asks is the wrong time to start building that record.



## The bottom line


TOSI didn’t end income splitting for family businesses, but it did end the era where it was a simple structuring exercise. Before paying, or continuing to pay — dividends to a spouse, child, or other family shareholder, it’s worth confirming which exception you’re actually relying on and whether you can support it. That review pairs naturally with a broader look at [salary versus dividends](https://www.everstonecpa.com/blog/salary-vs-dividends-2026) for your own compensation, since the two decisions usually get made together. If family members hold shares, the dividend rights written into your [shareholders’ agreement](https://www.everstonecpa.com/blog/shareholders-agreement-tax-implications) are part of the same picture.

FAQ

## Frequently asked questions




**What is TOSI?**

TOSI stands for tax on split income. It’s a rule that taxes certain income — most commonly dividends — paid by a private corporation to a related family member at the top personal marginal rate, removing the tax benefit of paying that income to someone in a lower bracket, unless a specific exception applies.



**Who does TOSI apply to?**

TOSI can apply to spouses, common-law partners, children, and other related individuals who receive dividends or certain other amounts from a private corporation connected to a family member who is or was actively involved in the business — unless the family member receiving the income qualifies for an exception.



**What is the “excluded business” exception?**

A family member may be exempt from TOSI if they’re actively engaged in the business on a regular, continuous and substantial basis — generally understood as averaging at least 20 hours per week during the year, or having done so in any five earlier years that don’t need to be consecutive.



**What are “excluded shares”?**

Excluded shares are a separate exception generally available to shareholders who are 25 or older, hold a meaningful direct equity stake in the corporation, and meet specific tests around the type of income the business earns. Meeting this test is fact-specific and should be confirmed with a CPA before relying on it.



**Is it still possible to split income with family members?**

Yes, but it now depends on meeting a specific, documented exception rather than simply issuing shares to a relative. Genuine involvement in the business, age, share structure, and reasonable-return tests all factor in — which is why income-splitting plans need a review before dividends are paid, not after.



**What records support a TOSI exception?**

The same records you would want in an audit: a log of hours worked, a written description of the family member’s role, minutes where shares or capital changed hands, and a note on how their compensation was decided. Because the exceptions turn on facts rather than share structure, the record has to be built as the year goes rather than reconstructed afterwards.



**Does TOSI apply to a salary paid to a family member?**

No. TOSI targets dividends and certain similar amounts, not employment income. A reasonable salary for work actually performed is employment income earned by the person doing the job, and it falls outside the split-income rules. It faces a different test instead: the amount has to be reasonable for the work, and it has to run through payroll properly.
