What Income Can Be Split Between Spouses in Canada?
by Briggs - September 2025
One of the most useful tax-planning opportunities for Canadian couples in retirement is income splitting. By allocating certain types of eligible pension income between spouses or common-law partners, a couple may be able to reduce their combined income tax and make better use of available tax credits.
But not every type of income qualifies. Employment income, investment income and many other sources generally cannot simply be divided between spouses for tax purposes. Understanding which income qualifies — and which does not — is an important part of retirement tax planning.
What Is Pension Income Splitting?
Pension income splitting allows a Canadian resident who receives certain types of eligible pension income to elect to allocate up to 50% of that eligible income to their spouse or common-law partner for tax purposes.
The income itself does not necessarily have to be physically transferred to the other spouse. Instead, the couple makes an election on their tax returns that changes how the eligible pension income is reported between them.
The strategy can be particularly valuable when one spouse has substantially more taxable retirement income than the other.
What Types of Income Can Be Split?
Several important sources of retirement income may qualify for pension income splitting, provided the applicable eligibility requirements are met.
Registered Pension Plan Income
Payments from an eligible registered pension plan (RPP) can generally qualify for pension income splitting.
This can include income from an employer-sponsored defined benefit pension or other qualifying registered pension arrangements.
RRIF Income
Registered Retirement Income Fund (RRIF) payments can qualify for pension income splitting, subject to the applicable age and tax rules.
This can be especially useful for retirees who have accumulated significant RRSP savings and are gradually converting those savings into retirement income.
It is important to distinguish between RRSP contributions and RRIF withdrawals. An RRSP balance itself is not something you simply split between spouses for tax purposes. However, qualifying RRIF income can potentially be eligible for pension income splitting.
Eligible Annuity Payments
Certain payments from qualifying life annuities and other registered retirement arrangements may also qualify as eligible pension income.
The specific type of annuity and how it is reported on the tax return matter, so couples should confirm the tax treatment of a particular payment before assuming it qualifies.
What Income Cannot Usually Be Split?
One of the biggest misconceptions about income splitting is that spouses can simply divide any household income between them. Canadian tax rules generally do not work that way.
Employment Income
You generally cannot take a salary or employment income earned by one spouse and simply report half of it on the other spouse's tax return.
For couples who are still working, strategies such as a spousal RRSP may help create a more balanced retirement-income profile in the future.
Interest and Investment Income
Interest income, dividends and other investment income are generally attributed to the person who owns the investment. Simply depositing investment assets into a spouse's name does not necessarily move the associated tax liability to that spouse.
Canada's attribution rules can apply when assets or money are transferred or loaned between spouses, making investment-income splitting considerably more complicated than pension income splitting.
Business Income and Dividends
Income from a privately held business can involve additional restrictions. In particular, the tax on split income (TOSI) rules can result in certain dividends and other amounts received by family members being taxed at a high rate unless an applicable exception or exclusion applies.
Business-owner families should therefore treat income splitting as a tax-planning issue, not simply as a way to move income between tax returns.
CPP Is Different: Pension Sharing vs. Pension Income Splitting
Canada Pension Plan (CPP) pension sharing is related to retirement income planning but is not the same thing as the federal pension income-splitting election.
Eligible spouses or common-law partners can apply to share CPP retirement pensions. CPP sharing can result in each spouse receiving an adjusted share of the couple's CPP retirement pensions, subject to the CPP rules.
This distinction matters because CPP sharing is administered through the CPP system, whereas pension income splitting is a tax election involving eligible pension income.
Why Would a Couple Split Income?
The primary reason to consider pension income splitting is to potentially reduce the couple's combined income tax.
Imagine one spouse has $80,000 of eligible pension income while the other has only $20,000 of taxable income. Depending on their circumstances, shifting some eligible pension income for tax purposes may result in a more balanced distribution of taxable income between the spouses.
The benefit is not necessarily the same for every couple. Other factors can affect the result, including tax brackets, age-related credits, medical expenses, government benefits and income-tested programs.
A Simple Example
Suppose Alice receives $60,000 of eligible pension income and Ben has $25,000 of other taxable income.
If Alice elects to split $30,000 of eligible pension income with Ben, the tax returns can reflect $30,000 less pension income for Alice and $30,000 more eligible pension income for Ben, subject to the applicable rules and election requirements.
The result could be a more even distribution of taxable income between the spouses. Whether that actually reduces their total tax bill depends on their complete financial picture.
Income Splitting Is Not Always Better
It is tempting to assume that splitting the maximum amount will always produce the greatest tax savings. That is not necessarily the case.
A couple should consider the effect on their entire retirement plan, including:
- Federal and provincial income tax
- Age-related tax credits
- Medical expense credits
- Income-tested government benefits
- Old Age Security (OAS) recovery tax
- RRIF withdrawal strategies
- Future required withdrawals
- Each spouse's overall retirement income
In other words, the goal should not simply be to move income from one spouse to the other. The goal is to understand how different withdrawal and income-splitting decisions affect the household's after-tax retirement income.
What About Spousal RRSPs?
A spousal RRSP can be an important strategy for couples who are still working and expect their retirement incomes to be significantly different.
The higher-income spouse can make a contribution to a spousal RRSP and generally receive the RRSP deduction, while the resulting retirement assets belong to the lower-income spouse.
Spousal RRSPs are therefore a pre-retirement planning strategy, whereas pension income splitting is primarily a strategy for managing eligible retirement income once it is being received.
How Retirementize Can Help
Income splitting is only one part of retirement tax planning. The timing of RRSP and RRIF withdrawals, pension income, CPP, OAS and other retirement income can all affect your lifetime tax bill.
Retirementize can help you model different retirement-income strategies and see how your projected income, taxes and after-tax cash flow change over time.
You can also explore related topics such as the RRSP meltdown strategy and retirement withdrawal planning.
