What Is Dividend Sprinkling, and Is It Still Legal in Canada?
Dividend sprinkling is a tax-planning strategy where a Canadian-controlled private corporation pays dividends to family members, a spouse, adult children, or a family trust who are taxed at lower marginal rates than the business owner. The goal is to move income from a high-rate taxpayer to a lower-rate one, reducing the family’s total tax bill on the same business earnings.
Dividend sprinkling is still legal in Canada, but the federal government dramatically narrowed the strategy’s usefulness in 2018 when it enacted the Tax on Split Income rules commonly called TOSI under section 120.4 of the Income Tax Act, effective January 1, 2018. TOSI eliminates the tax benefit of dividend sprinkling in many circumstances by taxing split income in the hands of the recipient at the top marginal federal rate, regardless of what the recipient would otherwise pay. Whether dividend sprinkling remains available to a particular business owner depends on the recipients’ ages, the nature of the business, and the role each family member actually plays in it.
How Dividend Sprinkling Worked Before 2018
Before the TOSI rules came into force, the structure was straightforward. A Canadian-controlled private corporation could issue shares to a spouse, adult children, or a family trust, and those shareholders could receive dividends taxed at whatever marginal rate applied to them personally. If the business owner faced a combined federal and provincial marginal rate above 50% and a spouse or adult child had little other income, directing dividends to them could save tens of thousands of dollars a year in tax on exactly the same corporate earnings.
The federal government had long expressed concern that this form of income splitting allowed high-income business owners to reduce their tax burden in ways not available to salaried employees, whose income is fixed to one taxpayer. After a widely criticized public consultation process in 2017, the Department of Finance enacted amendments effective January 1, 2018, that apply TOSI to most forms of passive income splitting through private corporations.
What the TOSI Rules Changed
When TOSI applies to an amount received by a family member, that amount is taxed at the highest marginal federal rate, which for most purposes eliminates any tax advantage of paying the dividend to that family member rather than retaining the income within the business or extracting it through the owner’s own hands. The TOSI rules cover taxable dividends from private corporations where the recipient is a “specified individual,” generally a Canadian resident related to the business owner and the income comes from a “related business” in which the owner or another related person is actively involved.
The rules do not apply to arm’s length situations. Dividends paid to shareholders who are unrelated to the controlling person are not subject to TOSI. The concern the rules address is specifically family arrangements where dividend recipients contribute little or nothing to the business that generated the income.
How TOSI Applies by Age Group
The TOSI rules draw distinctions based on the recipient’s age, and the practical impact of those distinctions is significant.
For recipients under 18, dividend sprinkling is effectively eliminated. Very limited exclusions exist, and for most family structures where a parent controls the business, dividends paid to minor children or through trusts for the benefit of minor children trigger TOSI at the top rate.
For recipients aged 18 to 24, TOSI also applies broadly. The most reliable exclusion available to a recipient in this age group is the active business involvement exclusion the individual must have worked an average of at least 20 hours per week in the business during the year or must have worked an average of at least 20 hours per week in the business for at least five taxation years over the course of their involvement. Where that standard is not met, TOSI will generally apply.
For recipients aged 25 and older, the rules are more flexible. A broader set of exclusions is available, including the excluded shares exemption and the reasonableness tests described below.
The Excluded Shares Exemption
For family members aged 25 and older, dividends may fall outside TOSI if the shares they hold qualify as “excluded shares” under section 120.4 of the ITA. To meet the definition, the recipient must own at least 10% of the votes and at least 10% of the fair market value of all issued and outstanding shares of the corporation. The corporation must not be a professional corporation as defined under the Income Tax Act. And less than 90% of the corporation’s business income in the prior year must have come from the provision of services.
When these conditions are met, dividends on those shares are not split income and are taxed at the recipient’s actual marginal rate. For a family business with a spouse or adult child who holds a meaningful equity stake in a non-service, non-professional business, this exemption can make dividend sprinkling work in the traditional sense for recipients 25 and older.
The Reasonableness Test for Working Family Members
Even where excluded shares do not apply, family members who genuinely work in the business or contribute capital to it may still receive dividends excluded from TOSI under a reasonableness test.
Under the labour contribution branch, a return is excluded from TOSI if it is reasonable given the work the recipient performs in the business. This requires actual, substantive involvement not nominal participation. The Canada Revenue Agency looks at the nature of the work, how much time was spent, and what an arm’s length employee would be paid for the same contribution. A spouse who takes on a genuine operational or administrative role and is compensated through dividends at a level consistent with the market value of that work can receive those dividends outside TOSI.
Under the capital contribution branch, a return is excluded from TOSI if it is reasonable given the property the recipient contributed to the business. This can apply where a family member contributed capital directly through a loan or equity investment and the dividend represents a reasonable return on that contribution.
In practice, the reasonableness tests require documentation. Business owners who intend to rely on these exclusions should maintain records of family members’ actual duties, hours, and capital contributions.
Professional Corporations and TOSI
Owners of professional corporations that are incorporated under provincial legislation for lawyers, doctors, dentists, accountants, engineers, and other regulated professionals face a specific limitation. Professional corporations are explicitly carved out from the excluded shares definition under the ITA. This means a spouse or adult child who holds shares of a professional corporation cannot rely on the 10% ownership test to receive dividends outside TOSI.
For professionals who operate through a corporation, dividend sprinkling to family members now depends entirely on the labour or capital reasonableness tests. A spouse who works in the practice in a genuine administrative or clinical capacity and is paid a dividend proportional to that contribution may be able to receive dividends outside TOSI. A family member with no involvement in the practice generally cannot.
What Income-Splitting Strategies Still Work After TOSI
TOSI did not eliminate all opportunities to reduce a family’s overall tax burden through a private corporation structure.
Salary paid to family members for genuine work remains outside TOSI because employment income is not split income. A spouse or adult child who performs real services for the business and receives reasonable compensation for that work through a salary is taxed on that salary at their own marginal rate. This is often the cleanest way to achieve income sharing where the family member is actively involved.
The holdco-opco structure remains a useful planning tool, though it addresses a different objective than income splitting. As described in the holdco-opco structure in Canada, surplus profits can flow from the operating company to a holding company as a tax-free intercorporate dividend under section 112 of the ITA, where they accumulate and are invested or distributed at the owner’s optimal time. This is a deferral and asset protection tool rather than a splitting tool, but it can significantly reduce the personal tax burden over time by allowing the owner to control when they extract income.
Capital gains on a future sale of qualifying small business corporation shares can still be structured to allow multiple family members to each claim the $1,275,000 lifetime capital gains exemption in some circumstances, though the interaction between TOSI and LCGE planning requires careful analysis. It should be addressed as part of a broader corporate reorganization well before any sale.
Spousal RRSPs remain a straightforward income-splitting mechanism available to any married couple, regardless of whether they operate a business.
Why Reviewing Your Existing Structure Matters
If a business owner set up a dividend-sprinkling arrangement before 2018 and has not reviewed it since the TOSI rules came into force, the dividends being paid to family members may now be subject to TOSI without anyone realizing it. CRA can reassess returns, and the penalties and interest on a TOSI assessment applied retroactively to prior years can be significant.
A corporate lawyer and tax advisor reviewing the existing structure can determine whether family members receiving dividends qualify under the excluded shares exemption or the reasonableness tests, advise on structural adjustments needed to bring the arrangement into compliance, and plan around the TOSI rules in a way that still achieves the family’s legitimate tax objectives. The TOSI rules are layered, and their interaction with corporate reorganization planning, including estate freezes, family trusts, and holdco structures, is an area where experienced legal and tax advice matters.
