Pension Income Splitting in Ontario: How Couples Can Save Thousands in Taxes

One of the Best Tax Breaks for Ontario Retirees

Pension income splitting is one of the most valuable tax strategies available to retired couples in Ontario. It allows you to allocate up to 50 percent of eligible pension income to your spouse on your tax returns, which can move income from a higher tax bracket to a lower one and reduce your combined tax bill by thousands of dollars every year.

Despite being available since 2007, many Ontario couples either do not know about pension splitting, do not understand how it works, or are not taking full advantage of it. If you and your spouse are retired or approaching retirement, this could be the single most impactful tax strategy you are not using.

How Pension Income Splitting Works

The concept is straightforward. At tax time, the higher-income spouse can elect to allocate up to 50 percent of their eligible pension income to the lower-income spouse. This is a paper allocation only — no money actually changes hands. The higher-income spouse reports less income, the lower-income spouse reports more, and the couple's combined tax bill drops because more income is taxed at lower marginal rates.

Both spouses must file a joint election using CRA Form T1032 (Joint Election to Split Pension Income) with their annual tax returns. Both spouses must agree to the split and sign the form. Note that pension splitting rules change significantly during a divorce or separation — if you are going through a marital transition, our financial planning for divorce guide covers the tax implications.

What Qualifies as Eligible Pension Income

Not all retirement income qualifies for splitting. The rules depend on your age:

If you are 65 or older, eligible pension income includes:

• RRIF (Registered Retirement Income Fund) withdrawals
• LIF (Life Income Fund) withdrawals
• Annuity payments from an RRSP, DPSP, or registered pension plan
• Payments from a registered pension plan (defined benefit or defined contribution)

If you are under 65, eligible pension income is limited to:

• Payments from a registered pension plan (defined benefit or defined contribution)
• Certain annuity payments received due to the death of a spouse

What Does NOT Qualify

Several common retirement income sources cannot be split:

• CPP and OAS — These have their own separate sharing/splitting rules
• RRSP withdrawals — Only RRIF withdrawals qualify (not direct RRSP withdrawals)
• Employment income — Even part-time work in retirement
• Investment income from non-registered accounts
• Rental income

This distinction matters. If you are under 65 and your retirement income comes primarily from RRSP withdrawals, you cannot split that income. Converting your RRSP to a RRIF earlier (even before the mandatory age 72 conversion) could allow you to split withdrawals starting at age 65 — a strategy worth discussing with your financial advisor.

The Math: How Much Can You Actually Save?

Here is a realistic scenario for a London, Ontario couple:

Without pension splitting:

• Spouse A: $95,000 in pension and RRIF income (marginal rate ~43.41%)
• Spouse B: $25,000 in CPP and OAS (marginal rate ~20.05%)
• Combined federal and Ontario tax: approximately $22,500

With pension splitting (allocating 50% of Spouse A's eligible pension income to Spouse B):

• Spouse A: $55,000 reported income (marginal rate ~29.65%)
• Spouse B: $65,000 reported income (marginal rate ~29.65%)
• Combined federal and Ontario tax: approximately $17,800

Tax savings: approximately $4,700 per year. Over a 25-year retirement, that is over $117,000 in total savings — all from a single form filed with your tax return.

The savings can be even larger when pension splitting helps one or both spouses avoid the OAS clawback, which begins at approximately $90,997 in net income for the 2024-2025 benefit year.

Pension Splitting and the OAS Clawback

This is where pension splitting becomes especially powerful. The Old Age Security clawback recovers 15 cents for every dollar of net income above the threshold. Combined with your marginal tax rate, this can push the effective rate above 60 percent.

If pension splitting brings the higher-income spouse's net income below the OAS clawback threshold, the savings go well beyond the tax bracket difference. Preserving even partial OAS benefits can add $3,000 to $7,000 per year in additional income for the household.

For many Ontario couples I work with, the combination of pension splitting and strategic tax planning is the difference between losing OAS entirely and keeping most or all of it. For a deeper dive into OAS clawback avoidance and deferral strategies, see our OAS optimization guide.

CPP Sharing vs. Pension Splitting

CPP has its own income sharing mechanism, separate from the T1032 pension splitting election. Under CPP sharing, spouses who both contributed to CPP during the time they lived together can share their CPP retirement pensions.

Key differences:

• CPP sharing must be applied for through Service Canada and actually redirects payments
• Pension splitting is a tax filing election — no payments change hands
• CPP sharing is based on the period of cohabitation and both spouses' CPP contributions
• Both can be used simultaneously for maximum tax reduction

CPP sharing is particularly useful when one spouse has a much larger CPP entitlement than the other. Combined with pension splitting of RRIF and pension income, the total tax savings for a London, Ontario couple can be substantial.

Strategic Considerations for Ontario Couples

How Much Should You Split?

You do not have to split the maximum 50 percent. The optimal amount depends on both spouses' total income, tax brackets, OAS clawback exposure, and eligibility for age-related tax credits. In some cases, splitting less than 50 percent produces a better result because it keeps both spouses in the same bracket without pushing the lower-income spouse too high.

This is where year-by-year retirement planning projections add real value. We model different splitting percentages for each year to find the amount that minimizes your combined tax bill.

Coordinate with RRSP Meltdown Strategy

If you are using an RRSP meltdown strategy — drawing down RRSPs before mandatory RRIF conversions at 72 — pension splitting interacts with this strategy. RRSP withdrawals before 65 cannot be split, but RRIF withdrawals after 65 can. The optimal approach often involves:

1. Converting a portion of the RRSP to a RRIF at or before age 65
2. Making RRIF withdrawals that qualify for splitting
3. Timing the meltdown to fill up lower tax brackets for both spouses

Early RRIF Conversion

There is no rule requiring you to wait until 72 to convert your RRSP to a RRIF. If you are 65 and want to take advantage of pension splitting, converting part or all of your RRSP to a RRIF lets your withdrawals qualify as eligible pension income for splitting purposes.

This also qualifies the receiving spouse for the $2,000 pension income tax credit if they do not already have eligible pension income of their own. That credit alone is worth up to $600 in combined federal and Ontario tax savings.

Business Owner Considerations

For Ontario business owners withdrawing corporate retained earnings in retirement, pension splitting does not apply to dividends paid from a corporation. However, if the business owner has built up RRSP or RRIF savings alongside the corporate investments, splitting the registered account withdrawals while carefully timing dividend payments can optimize the overall tax picture.

Coordinating this with corporate financial planning ensures the total tax burden across both personal and corporate accounts is minimized.

Common Mistakes to Avoid

Not filing Form T1032. Pension splitting is not automatic. You must file the joint election every year. If you forget, you lose that year's savings — there is no way to go back and retroactively split income from a prior year (beyond the normal reassessment window).

Splitting too much. Pushing the lower-income spouse into a higher bracket or above the OAS threshold defeats the purpose. The split should be optimized, not maximized.

Ignoring provincial tax differences. Ontario has its own tax brackets and surtax. The optimal split percentage for federal tax may differ from the optimal split for Ontario tax. Your financial advisor should model both.

Forgetting about other income. If the lower-income spouse has investment income, part-time employment, or rental income that pushes them higher, the pension split should account for all income sources, not just pension income.

Not considering the pension income tax credit. If the lower-income spouse does not have $2,000 in eligible pension income, splitting enough to reach $2,000 unlocks the pension income amount credit for both spouses.

How a Financial Advisor Helps

Pension income splitting sounds simple, but optimizing it requires modelling the interaction between multiple income sources, tax brackets, OAS clawbacks, tax credits, and the timing of RRSP/RRIF conversions. The optimal split can change from year to year as income, tax rules, and personal circumstances evolve.

As a financial advisor in London, Ontario, I build year-by-year retirement income projections that model pension splitting alongside your complete tax picture. The result is a precise recommendation for how much to split each year, coordinated with your investment management, CPP timing, and withdrawal strategy.
