What is income splitting?

Income splitting is a strategy that aims to level out income earned by married or common-law spouses with the goal of reducing the household’s tax bill. An added benefit is that income splitting can help protect income-tested benefits such as Old Age Security (OAS), which is reduced at higher income levels. Canada has a graduated tax system, meaning that as Canadians earn more, they pay a higher rate of tax on those higher earnings.

How does income splitting work?

Income splitting works by shifting taxable income from the higher-earning spouse to the lower-earning spouse, effectively reducing the household’s combined tax burden. Because Canada’s tax system applies higher rates at higher income levels, redistributing income between spouses moves some of that income into a lower tax bracket — and the household as a whole pays less tax as a result.

The effect of a graduated tax system is that two partners who each earn $100,000 tend to pay less total tax than two partners who earn $150,000 and $50,000, respectively. That’s where income splitting can be beneficial. By using eligible income splitting strategies — such as contributing to a spousal Registered Retirement Savings Plan (RRSP) or splitting pension income in retirement — the household can reduce the total tax paid.

Income splitting is not a single tactic but a collection of strategies available at different life stages. Some apply during your working years, others take effect in retirement, and some are specific to business owners. Knowing which tools are available to you, and when to use them, is key to making the most of this approach.

Income splitting rules in Canada

Canada’s income splitting rules are set out in the Income Tax Act and govern which types of income can be split, between whom and under what conditions. Here are the key rules to understand

Pension income splitting

Spouses and common-law partners can split up to 50% of eligible pension income on their tax returns. This requires completing Canada Revenue Agency (CRA) Form T1032 — Joint Election to Split Pension Income — each year. It’s an annual election, not a permanent arrangement, which gives you flexibility to adjust based on each year’s income level.

Spousal RRSP contributions

The higher-income spouse contributes to a spousal RRSP in the lower-income spouse’s name. The contributor claims the tax deduction, and the lower-income spouse owns the funds and declares withdrawals as income in retirement. Contributions must generally remain in the plan for the rest of the calendar year plus two more years for this strategy to work properly and for the attribution rules to be avoided.

Canada Pension Plan (CPP)/Quebec Pension Plan (QPP) sharing

Couples can share CPP/QPP income, whether one or both spouses contributed. The shareable portion depends on how many months spouses lived together while contributing to the CPP/QPP.

Tax on Split Income (TOSI) 

Business owners face strict rules under TOSI that limit income splitting with family members unless specific conditions are met. While income splitting opportunities still exist, these rules prevent unreasonable income splitting through private corporations.

Attribution rules

The Income Tax Act includes attribution rules that prevent certain income splitting strategies from working. For example, if you simply transfer money to your spouse and they invest it, any income and capital gains on those investments may be attributed back to you and taxed in your hands. Understanding these rules, and how they interact, is essential for building an effective income splitting strategy.

Which types of income qualify for income splitting?

Income splitting isn’t as simple as totaling what each spouse earns and dividing it in half. Only certain types of income qualify, and the biggest opportunity is in retirement when you can split up to 50% of eligible pension income with your spouse or common-law partner.

Pension income eligible for splitting includes:

  • Life annuity payments from a registered pension plan (RPP) at any age
  • Variable pension benefits from an RPP starting at age 65
  • Withdrawals from a Registered Retirement Income Fund (RRIF) or Life Income Fund (LIF) starting at age 65
  • Income from an annuity, including one purchased with an RRSP or Deferred Profit-Sharing Plan (DPSP), starting at age 65

Couples can also share CPP/QPP income, whether one or both spouses contributed. You cannot split OAS, U.S. Individual Retirement Account (IRA) income or any other foreign pension.

Income splitting in Canada: Before and after age 65

To be eligible for income splitting in Canada, you must be married or in a common-law partnership recognized by the CRA. You cannot split income with a dating partner, a roommate or a sibling — the relationship must meet the CRA’s definition of spouse or common-law partner.

Pension income splitting eligibility

To split pension income, both you and your spouse or common-law partner must be Canadian residents at the end of the tax year. The income being split must come from an eligible source (see the section below on what income qualifies). There is no minimum age requirement for splitting life annuity payments from a Registered Pension Plan (RPP), but other types of pension income require the recipient to be 65 or older.

Spousal RRSP contributions

Spousal RRSP contributions are the most accessible income splitting tool during your working years. The higher-income spouse contributes to a spousal RRSP in the lower-income spouse’s name, claiming the deduction at their marginal tax rate. The lower-income spouse then withdraws those funds in retirement, ideally at a lower marginal rate. This strategy is especially effective when there’s a meaningful income gap between spouses.

CPP/QPP sharing

CPP/QPP sharing becomes available once both spouses are at least 60 years old and receiving their pension, so this option opens up before the age-65 threshold that applies to other pension splitting.

Life annuity payments from an RPP

Life annuity payments from an RPP are eligible for pension income splitting at any age — meaning that if you receive an RPP annuity before age 65, you may still be eligible to split that income with your spouse.

TOSI rules and business owners

If you own a private company, certain income splitting strategies involving family members may be available before age 65, but these are subject to complex TOSI rules (see the section on business owners below). Once a business owner turns 65, the TOSI rules no longer apply and it becomes easier to split income through the company.

Talk to an Edward Jones financial advisor about how planning early can set your household up for significantly lower taxes in retirement.

Can you split income while working?

Yes. A spousal or common-law partner RRSP allows working couples to split some income right away and lay the groundwork for more equal income in retirement. It’s an effective strategy when a couple has different incomes now and expects to have different incomes in retirement. It can also work well when there’s a significant age gap between spouses, because the older spouse can continue contributing to a spousal or common-law partner RRSP until the end of the year the younger spouse turns 71.

Here’s how it works: the higher-income spouse contributes to the spousal or common-law partner RRSP on behalf of the lower-income spouse. In return, the higher-income spouse uses their RRSP contribution room and deducts the contribution at their marginal tax rate, which tends to be higher if their income is higher. The deduction applies in the year of the contribution but can be carried forward and used anytime. Meanwhile, the lower-income spouse builds up retirement savings, and in retirement, withdrawals from the spousal or common-law partner RRSP are taxed in that spouse’s hands.

It’s important to note that contributions to a spousal or common-law partner RRSP must generally remain in the plan for the rest of that calendar year plus two more years before withdrawals become taxable to the spouse rather than the contributor.

Can business owners split income with family members?

If you own a private company and your spouse or adult children work for you, it may be possible to pay them a salary taxed at their marginal tax rate. If they are shareholders of your company, you may be able to pay them dividends. However, there are strict and complex TOSI rules that must be met for this strategy to work. Otherwise, the dividends are taxed at the top marginal rate, negating any tax benefit of this strategy. Once the business owner turns 65, the TOSI rules no longer apply and it becomes easier to split income in this way. It’s essential to work with a tax professional if you’re interested in splitting business income with family members.

Income splitting: What you need to know

The core objective of income splitting is to reduce the household’s combined tax bill by moving income from a higher tax bracket into a lower one. Here’s what you need to understand about how the tax mechanics work.

Marginal tax rates matter most

Canada’s federal tax brackets mean income above certain thresholds attracts progressively higher rates. Provincial taxes add another layer. When one spouse earns significantly more than the other, the household effectively loses money to the higher marginal rates applied to the top portion of the higher earner’s income.

The annual election for pension splitting

Pension income splitting requires filing CRA Form T1032 each year. You don’t have to split the maximum 50% every year — you can split any amount up to that maximum. Each year is a fresh decision, which lets you and your spouse optimize based on that year’s actual incomes, deductions and tax credits.

Attribution rules

Canada’s attribution rules limit informal income splitting. If you give or loan money to your spouse and they invest it, investment income and capital gains on those funds are generally attributed back to you for tax purposes — unless the loan is at the CRA’s prescribed interest rate and interest is actually paid each year.

RRSP withdrawals in retirement

When the lower-income spouse withdraws from the spousal RRSP in retirement, those withdrawals are taxed in their hands — not the contributor’s. This is one of the most powerful aspects of the strategy, but it depends on the three-year rule being satisfied.

Tax deductions vs. tax credits

RRSP contributions generate a tax deduction, which reduces taxable income. The value of that deduction depends on your marginal tax rate — which is why it’s most advantageous for the higher-income spouse to make the contribution.

Does income splitting affect the OAS clawback?

Yes. This is one of the most important, and most often overlooked, benefits of income splitting in retirement. OAS benefits are subject to a recovery tax, commonly known as the “OAS clawback," when net income exceeds a threshold set by the CRA each year. From July 2026 to June 2027, the clawback begins at a net income of $93,454, and OAS is fully eliminated at approximately $151,668. For every dollar of net income above the threshold, $0.15 of OAS is clawed back.

Income splitting can help one or both spouses keep their net income below the clawback threshold. For example, if one spouse’s net income is $110,000 and they elect to split $25,000 of eligible pension income with their spouse, their net income drops to $85,000 — below the threshold — which protects their full OAS benefit.

It’s important to note that you cannot split OAS income itself, as it is specifically excluded from pension income splitting. However, by splitting other eligible pension income, you can reduce net income and protect OAS entitlement.

This interplay between income splitting and the OAS clawback is one more reason to review your income splitting strategy each year as income levels change.

Disadvantages of income splitting

While income splitting can deliver meaningful tax savings, it isn’t without its drawbacks. Here’s what to keep in mind.

  • Complexity. Income splitting strategies, especially those involving spousal RRSPs, pension elections and TOSI rules, require careful planning, ongoing tracking and often the involvement of a tax professional. The rules are detailed, and the consequences of getting them wrong can be costly.
  • Attribution rules. Canada’s attribution rules limit what you can do informally. You cannot simply transfer assets to your spouse to reduce your tax bill, as income and gains on those assets may be attributed back to you.
  • The three-year waiting period for spousal RRSPs. Contributing to a spousal RRSP and then withdrawing funds too soon triggers attribution rules. This requires forethought about when the lower-income spouse intends to make withdrawals.
  • TOSI rules for business owners. Business owners who want to split income with family members face strict TOSI rules that can result in dividends being taxed at the top marginal rate if conditions aren’t met.
  • Not always beneficial. If both spouses earn similar incomes, income splitting may offer little or no tax savings. The benefit is greatest when there’s a significant income gap between partners.
  • Annual election required for pension splitting. Pension income splitting is not automatic — it requires filing Form T1032 each year. Missing this step means missing the opportunity for that tax year.
  • Understanding both the advantages and the limitations of income splitting helps you make more informed decisions about whether and how to use it.

Example: Income splitting in action

Consider an Ontario couple in retirement where one spouse has an income of $160,000 and the other has an income of $40,000. Without income splitting, the higher earner pays federal tax at a marginal rate of 43.4%, and their OAS benefit is entirely clawed back. With pension income splitting, up to 50% of eligible pension income can be allocated to the lower-income spouse.

If the couple allocates $50,000 of eligible pension income to the lower-income spouse, the household’s incomes shift to approximately $110,000 and $90,000. This moves both spouses into lower federal brackets and can also protect a significant portion of the higher earner’s OAS benefit, depending on the clawback threshold in that year.

The actual savings depend on each household’s income mix, applicable deductions, provincial tax rates and the types of eligible income available. An Edward Jones financial advisor can run personalized numbers for your situation.

Income splitting requires regular reviews

Income splitting, like all tax planning, is not a “set it and forget it” strategy. It’s a good idea to review your situation with your financial advisor every year so you can adjust as needed.

During your working years, for example, one spouse may start out earning a higher income, but that can change. Either spouse may change careers, taking a step up or down in earnings. Either spouse may also move to a job with a more or less generous pension plan, which affects RRSP contribution room. Couples can have a spousal or common-law partner RRSP for each spouse, so if your circumstances or outlook for retirement change, you can consider switching who contributes to whose retirement savings.

In retirement, income levels tend not to change as much, but one spouse may decide to keep working longer than the other, or inherit an investment portfolio that generates significant income. These situations too may require fine-tuning of the couple’s income splitting strategy, especially as they relate to the OAS clawback threshold.
