Income splitting options for families in Canada

Income splitting means arranging for some income to be taxed in the hands of a family member who pays a lower rate. Canada’s progressive rates make that attractive, and Parliament has written rules to stop the easy versions of it. This article is a decision aid for Ontario families rather than a set of tricks. It sorts the common options into those that generally work, those that work only with conditions and those that tend to backfire, and it points to the neighbouring pages that cover each one in more depth.

One household income, several ways to split it

What to take away

  • Gifting money to a spouse or a minor child usually leaves the investment income taxed to you under the attribution rules.
  • A spousal RRSP, a properly documented prescribed-rate loan, an RESP and reasonable family wages are the main options that can work.
  • Dividends paid to family from a private corporation face the tax on split income, so check an exclusion applies before paying them.

Why families look at income splitting

Because tax rates rise with income, the same household income can be taxed less when it is spread across two people. For 2026 the federal rate is 14% on the first $58,523 of taxable income and 20.5% on the next slice up to $117,045. Ontario’s rate is 5.05% up to $53,891 and 9.15% up to $107,785. The gap between those rungs is the opportunity.

The rules aim to stop one person from simply handing income to another on paper. Anything you choose should be real: the money, the work or the ownership has to actually belong to the person who reports the income. The sections below start with the simplest options and end with the ones that need professional advice.

An illustrative example of the gain

These numbers are illustrative only. Suppose one partner’s next dollar is taxed in the 20.5% federal and 9.15% Ontario bands, a combined 29.65%. The other partner’s next dollar falls in the 14% federal and 5.05% Ontario bands, a combined 19.05%. Moving $10,000 of income from one to the other would then cut the household’s tax by roughly $1,060.

The example ignores the Ontario surtax, the Ontario health premium, credits and benefit clawbacks, all of which can move the real figure. It also shows the ceiling on the idea. The saving is a few percentage points of the amount moved, so it matters most when the gap between the two incomes is large and the amount moved is substantial.

Why gifts to a spouse or child often do not work

The attribution rules are the main obstacle. The CRA’s archived bulletin on spousal transfers explains that income earned and capital gains realized on property you transfer or lend to your spouse are generally treated as yours, unless the spouse paid fair market value or you are living apart because the relationship broke down. The rule follows substituted property too, so selling the gift and buying something else does not reset it.

For minors, the archived bulletin on related minors says income from property you transfer or lend to a child under 18, or to a trust for that child, is generally treated as yours for each year before the year the child turns 18. A related minor can also include a niece or nephew. Taxable capital gains on that property are not attributed, but interest and dividends are. A bank account for a child funded from your pocket is therefore usually still taxed to you.

A spousal RRSP

With a spousal RRSP you contribute to a plan owned by your spouse or common-law partner and claim the deduction yourself, within your own RRSP deduction limit. The CRA allows contributions to a spouse’s plan until December 31 of the year the spouse turns 71. The aim is to build retirement savings in the lower-income partner’s name so later withdrawals are taxed at a lower rate.

The timing rule matters. If you contributed to any spousal plan in the year of a withdrawal or either of the two preceding years, some or all of the withdrawal is generally taxed to you instead, calculated on Form T2205. A spousal RRSP is therefore a long-term tool, not a way to move money across within a few years. Our spousal RRSP entry explains the mechanics.

A prescribed-rate loan to a lower-income spouse

Attribution does not apply to a loan where interest is charged at a rate at least equal to the lesser of the CRA’s prescribed rate and a commercial rate when the loan is made. The archived bulletin adds a firm condition: all the interest must be paid no later than 30 days after the end of each calendar year. A missed payment can end the protection for that year and later years.

The CRA’s prescribed rate for low-interest loan benefits is 3% for October 1 to December 31, 2026. The rate changes quarterly, so confirm the rate for the quarter you sign. The borrower invests the money, pays the interest from their own funds, and the interest is generally income to you, while the investment return above that interest is intended to be taxed to the borrower. Put the loan in writing and keep proof of every interest payment.

RESPs and education savings

An RESP does not split income in the strict sense, but it shifts tax to the student. Contributions are not deductible and growth is tax-sheltered. When the money comes out as an educational assistance payment it is taxed in the student’s hands, where it is often low or zero after tuition and basic credits.

The government adds a basic grant of 20% of annual contributions, up to $500 a year per child or $1,000 if there is unused room, with a $7,200 lifetime limit on the grant. Lower-income families may qualify for extra grant and for the Canada Learning Bond. The lifetime contribution limit is $50,000 per beneficiary and over-contributing is taxed at 1% a month. Each child needs a SIN before you contribute.

Family wages and dividends from your business

If you run a business, paying a spouse or adult child for real work can move income to them. The pay has to be reasonable for the work performed, actually paid and reported, and the other person must truly do the work. Our guide on paying family members through your business sets out the payroll side and the records the CRA expects.

Dividends are different. Taxable dividends from a private corporation paid to a family member can fall under the tax on split income, which can tax the amount at a higher rate unless an exclusion applies. The CRA lists exclusions that depend on age, work in the business and whether the shares are excluded shares, so a dividend to a spouse or child needs a documented reason before it is paid. See our entries on the tax on split income and on salary versus dividends.

What to bring and how to choose

Start with the simpler questions. Who has the higher marginal rate, and will that change with retirement, leave or a business sale? Which credits and deductions, such as child care or donations, should be claimed by the lower-income partner, as covered in our child care and donation articles? Pension income can also be split in retirement, which has its own guide.

Bring both partners’ most recent notices of assessment, RRSP deduction limits, a list of any gifts or loans between you, loan agreements and interest records, corporate shareholder details and any RESP statements. Ask an accountant to model the household tax before you commit money, because the saving is usually modest and the penalties for getting attribution wrong are not.
