Income splitting is not dead. It just does not look the way most people think it does. If your plan is to pay dividends to your spouse or adult children who do not work in the business, you will end up paying more tax, not less. But there are still real, legal strategies that shift income to lower-bracket family members in 2026, they just have to be structured properly.
Here is what actually works, what does not, and where most business owners go wrong.
What Income Splitting Is and Why It Works
Canada has a graduated tax system. The top combined marginal rate in Ontario is 53.53%, while the lowest bracket is closer to 20%. If one member of a family earns most of the household income and another earns very little, the household ends up paying tax at a much higher effective rate than it would if the same total income were spread across both people.
Income splitting is the strategy of legally shifting income from a high-bracket family member to a lower-bracket one. Done right, the total household tax bill drops without changing how much the family earns. Done wrong, and this is where TOSI comes in, the shifted income gets taxed at the top marginal rate anyway.
The TOSI Reality Check
In 2018, the federal government dramatically expanded the Tax on Split Income (TOSI) rules. Before the change, incorporated business owners routinely paid dividends to spouses and adult children through their private corporations to shift income to lower brackets. That is largely gone.
Under the current rules, any dividend paid from a private corporation to a family member is taxed at the top marginal rate (53.53% in Ontario) unless the recipient qualifies for one of the enumerated TOSI exceptions. The most common exceptions are:
Excluded Business exception: The family member has worked in the business for an average of at least 20 hours per week during the year, or during any five prior years. Once the five-year test is met, dividends paid to that family member are excluded from TOSI for life.
Excluded Shares exception: The family member is 25 or older, owns at least 10% of the votes and value of the corporation, and the corporation is not a professional corporation, does not earn most of its income from services, and does not earn a significant portion of its income from a related business.
Age 65+ exception: Once the business owner turns 65, dividends paid to the spouse are exempt from TOSI. This aligns TOSI with the pension income splitting rules that already treat retirement income more flexibly.
If a family member does not fit into one of these exceptions and receives a dividend, the income is taxed at the top rate regardless of their actual bracket. The income-splitting benefit disappears entirely.
What Still Works in 2026
Pension income splitting: If you are receiving eligible pension income, including RRIF or LIF withdrawals after age 65, or a defined benefit pension at any age, you can allocate up to 50% of it to your spouse at tax time by filing Form T1032. There is no need to actually transfer the money. The allocation happens on paper. This remains one of the simplest and most valuable splitting strategies available to Canadian retirees.
Spousal RRSPs: The higher-earning spouse contributes to a spousal RRSP in the name of the lower-earning spouse. The contributing spouse gets the deduction, but the funds belong to the recipient spouse and are eventually taxed in their hands at their lower rate. Attribution rules apply for three calendar years after each contribution, so plan the timing carefully.
CPP pension sharing: Spouses both aged 60 or older can apply to share their CPP retirement pensions. The portion of each spouse’s CPP earned during the years they lived together is split evenly. If one spouse has a much larger CPP entitlement than the other, this can produce meaningful annual savings.
Prescribed rate loans: The higher-income spouse can lend money to the lower-income spouse at the CRA’s prescribed rate, currently 3% for Q2 and Q3 of 2026, documented with a promissory note. The recipient spouse invests the funds in their own name. Any investment return above the 3% interest cost is taxed in the lower-income spouse’s hands. The interest must be paid every year by January 30. Miss that deadline and the entire strategy unwinds. The 3% rate is locked in for the life of the loan, so timing matters.
Paying a reasonable salary to family members who actually work in the business: If your spouse or adult child performs real work for your corporation, you can pay them a reasonable salary for that work. The salary is deductible to the corporation and taxed as employment income in the family member’s hands, at their marginal rate. The keys are that the work must be genuine, the salary must be reasonable for the work performed, and you should be able to document both.
TFSA gifting to a spouse: You can give funds to your spouse to contribute to their TFSA without triggering the attribution rules. Because TFSA growth and withdrawals are tax-free, the income is not attributed back regardless of who provided the money. This is one of the cleanest income-splitting strategies available.
What Does Not Work (and Why People Still Try)
Paying dividends to a spouse or adult child who is not genuinely involved in the business will be caught by TOSI. So will trying to sprinkle income through a family trust when the beneficiaries do not qualify for a TOSI exception.
Gifts or interest-free loans between spouses trigger the attribution rules under section 74.1 of the Income Tax Act, any investment income earned on the transferred funds gets attributed back to the higher-income spouse. This is why the prescribed rate loan structure exists in the first place.
Paying income to a minor child, whether through dividends, a trust, or otherwise, will almost always be caught by either TOSI or the attribution rules. There are very narrow exceptions, but the general rule is that shifting income to a minor for tax purposes does not work.
How Cassar CPA Can Help
Income splitting works best when it is planned properly and documented from the start. A prescribed rate loan without a promissory note, or a salary to a spouse without a job description and payroll records, can unwind under CRA scrutiny.
