Quick Answer
After divorce in Ontario, income splitting works very differently than during marriage. Spousal support is tax-deductible to the payor and taxable to the recipient under s.60(b) of the Income Tax Act — one of the few remaining post-divorce income-shifting tools. RRSP and RRIF assets can be transferred tax-free using Form T2220, CPP credits earned during the marriage are split equally by law, and eligible pension income can be split 50/50 with a new partner in future years. Done correctly, these strategies can reduce a separated household's combined tax bill by thousands each year.
Key Takeaways
- 1Spousal support (alimony) is fully deductible to the payor and fully taxable to the recipient under s.60(b) and s.56(1)(b) of the Income Tax Act — but only if paid under a written separation agreement or court order and made periodically (not as a lump sum).
- 2RRSP and RRIF assets can be transferred to an ex-spouse's registered plan tax-free under s.146(16) of the ITA — no withholding, no immediate tax. Both spouses need a signed agreement and CRA Form T2220.
- 3CPP credit splitting is mandatory in Ontario: contributions both spouses made during the marriage years are pooled and divided equally by Service Canada, permanently changing each person's CPP benefit.
- 4Defined benefit pensions can be divided via a lump sum transfer to a LIRA or by splitting at source — the non-member spouse must work through the pension administrator and Ontario's FSRA rules.
- 5Pension income splitting (s.60.03 ITA) allows up to 50% of eligible pension income to be allocated to a new spouse or common-law partner in future years — but it ends with the marriage or relationship, and an ex-spouse receives no ongoing benefit.
- 6Child support payments are neither deductible to the payor nor taxable to the recipient — only spousal support creates the tax deduction/inclusion.
- 7Common-law couples who separate after living together for at least 12 months (or sharing a child) have the same CPP credit splitting rights as married couples, but Ontario's Family Law Act equalization rules do not automatically apply to property.
- 8The year of separation often creates unusual income spikes. Proactive tax planning with an accountant before December 31 of the separation year can save thousands.
Quick Summary
This article covers 8 key points about key takeaways, providing essential insights for informed decision-making.
The Shift From Married to Separated: What Changes
When you were married or in a common-law partnership, income splitting typically worked through spousal RRSP contributions, pension income splitting under s.60.03 ITA, and holding income-producing assets in the lower-earner's name. After separation, most of these strategies end. You are now two separate taxpayers with separate returns, separate brackets, and separate RRSP plans.
But the income splitting opportunity does not disappear — it transforms. New tools emerge: spousal support deductibility, RRSP rollovers, CPP credit splitting, and eventually pension income splitting with a new partner. Used correctly, these can significantly reduce your combined post-divorce tax burden.
1. Spousal Support: The Most Powerful Tax Tool Post-Divorce
Under s.60(b) of the Income Tax Act, periodic spousal support payments are fully deductible to the payor and fully included in income for the recipient under s.56(1)(b). This is one of the last income-shifting mechanisms that survives a marriage breakdown.
How It Works
The payor — typically the higher earner — deducts support payments from taxable income. The recipient — typically the lower earner — adds them to income. Because the recipient is in a lower bracket, the combined household pays less tax overall.
Example:
- Alex earns $180,000/year (Ontario marginal rate: ~53%)
- Jordan earns $40,000/year (Ontario marginal rate: ~29%)
- Alex pays Jordan $3,000/month in spousal support = $36,000/year
Tax result:
- Alex saves: $36,000 × 53% = $19,080 in taxes
- Jordan pays: $36,000 × 29% = $10,440 in additional taxes
- Net household tax saving: $8,640/year
The Three Requirements
CRA requires all three conditions:
- Periodic payments: Monthly or other regular intervals. A single lump sum does NOT qualify under s.60(b).
- Living apart: Payor and recipient must be living separately at time of payment.
- Written agreement or court order: Payments must be made under a formal separation agreement or court order specifying the amount and schedule.
Child Support vs. Spousal Support
Child support paid under agreements dated after May 1, 1997 is neither deductible nor taxable — it has no income tax consequence for either party. This asymmetry creates planning opportunities: higher spousal support (deductible) with lower child support can produce better after-tax outcomes than a flat total support figure, depending on both parties' brackets. A divorce financial analyst can model multiple scenarios.
2. RRSP and RRIF Transfers: Tax-Free on Breakdown
One of the most important provisions in Canadian tax law for divorcing couples is s.146(16) of the ITA, which allows RRSP and RRIF assets to transfer between ex-spouses on a completely tax-deferred basis.
What You Need
- A signed separation agreement or court order specifying the transfer amount
- CRA Form T2220: Transfer from an RRSP, RRIF, PRPP or SPP on Breakdown of Marriage or Common-law Partnership
- Submit directly to the financial institution holding the plan — not to CRA
Critical Points
- The transfer does not use RRSP contribution room
- The transfer must go directly between plans — a personal withdrawal followed by deposit to your ex's plan loses the tax deferral
- Both spouses must sign the T2220
- Common-law couples qualify under the same rules
Example: Sandra has $180,000 in her RRSP. Under the settlement, David receives $60,000. Using T2220, $60,000 transfers directly to David's RRSP. No tax is triggered at transfer. When David withdraws funds in retirement, he pays tax at his rate at that time.
3. CPP Credit Splitting: The Mandatory Equalization
CPP credit splitting is not optional — it is a right either spouse can invoke after separation under the Canada Pension Plan Act (s.55 and s.55.1).
How It Works
Service Canada takes all CPP contributions both spouses made during the years of cohabitation, combines them, and splits them equally. Contributions made before the relationship and after separation are untouched.
Example: Mark and Lisa were married from 1996 to 2024 (28 years). Mark contributed to CPP for all 28 years; Lisa contributed for 12 (at home with children for 16). After credit splitting, both parties receive credit for 50% of the combined contributions during those 28 years. Mark's future CPP benefit decreases; Lisa's increases.
For couples with a significant earnings gap over a long marriage, this can shift $300–$600/month in CPP benefits — a meaningful and permanent change.
Applying
Either party applies to Service Canada using ISP-1901. You need marriage/cohabitation dates and your divorce certificate or separation agreement. The split is retroactive to the date of separation.
4. Defined Benefit Pensions: Division Rules in Ontario
If one or both spouses have a defined benefit pension — teachers', OPP, federal government, or private sector DB plan — it is typically the most valuable asset in the marriage and the most complex to divide.
The Two Options
Option 1: Lump-Sum Transfer to a LIRA
The non-member spouse receives a share of the pension's commuted value, transferred to a Locked-In Retirement Account. The LIRA grows tax-sheltered and must eventually convert to a Life Income Fund (LIF) at retirement.
- Advantage: Non-member spouse gains independence and control
- Disadvantage: LIRA funds are locked in; annual LIF maximums apply
Option 2: Division at Source
The pension is divided administratively, and each party receives a separate income stream when the pension member retires.
- Advantage: Non-member participates in full pension value rather than a discounted commuted value
- Disadvantage: Must wait until the member retires; no control over the asset in the meantime
Ontario Rules
Ontario's Pension Benefits Act and the FSRA govern pension division. Government pensions (Ontario Teachers', OMERS, federal public service) each have their own division frameworks. The pension must be valued by an actuary before the settlement is signed — valuations can differ significantly based on actuarial assumptions.
5. Pension Income Splitting Post-Divorce: The Future Opportunity
Pension income splitting (s.60.03 ITA) allows up to 50% of eligible pension income to be allocated to a spouse or common-law partner, reducing the household's combined tax bill. What qualifies: defined benefit pension payments (at any age), RRIF withdrawals if 65 or older, CPP, QPP, and qualifying annuity income.
After divorce, you cannot split income with your ex. But once you form a new qualifying relationship — remarriage or common-law after 12 months — the strategy is fully available again.
Example: You receive $80,000/year from a DB pension. New partner earns $25,000/year. Allocating $40,000 to your partner brings your income to $40,000 and theirs to $65,000. Combined tax saving: approximately $9,000–$14,000/year depending on brackets.
6. Common-Law vs. Married: The Critical Differences
| Area | Married | Common-Law (12+ months) |
|---|---|---|
| CPP credit splitting | ✅ Yes | ✅ Yes |
| RRSP/RRIF tax-free transfer | ✅ Yes | ✅ Yes |
| Spousal support deductibility | ✅ Yes | ✅ Yes |
| Property equalization (FLA) | ✅ Automatic | ❌ No — must sue |
| Pension division (Ontario PBA) | ✅ Yes | ✅ Yes (3 years or with a child) |
For common-law couples, the biggest risk is the property equalization gap. Married spouses automatically trigger net family property equalization under the Family Law Act. Common-law partners must claim unjust enrichment or constructive trust through the courts — a harder and more expensive path. If you are in a long-term common-law relationship, consider a cohabitation agreement that explicitly addresses property division.
7. Tax Planning in the Year of Separation
The year you separate is often your most complex tax year. Several issues converge:
Retroactive Spousal Support: If your agreement includes retroactive support covering prior years, CRA taxes the full amount in the year received. You can apply for lump-sum income averaging under s.110.2 and s.120.31 — a calculation that taxes the lump sum as if received in the years it was meant to cover. This can save thousands.
Property Transfers and Capital Gains: Transferring the family home as part of equalization can trigger a deemed disposition. File your principal residence designation using Form T2091 and Schedule 3 to claim the exemption.
Update Your TD1: If you begin paying or receiving spousal support mid-year, update your employer withholding. The deduction (for payor) or additional income (for recipient) affects your tax balance owing in April.
Spousal RRSP Attribution: Once separated, you can no longer contribute to a spousal RRSP. Any withdrawals by your ex within three years of your last contribution may still be attributed back to you under spousal RRSP attribution rules.
Beneficiary Designations: Update RRSP, RRIF, TFSA, and life insurance beneficiary designations immediately. In Ontario, divorce does not automatically remove an ex-spouse as beneficiary.
Putting It Together: A Real Ontario Example
Background: Michael (52, income $160,000) and Karen (49, income $55,000) separate after 22 years in Milton, Ontario. Michael has a company DB pension and $220,000 in RRSPs. Karen has $90,000 in RRSPs and smaller CPP contributions from part-time work.
Income Splitting Strategies Applied:
- Spousal support: Michael pays Karen $4,200/month ($50,400/year). Michael saves ~$26,700 in tax; Karen pays ~$14,600. Net household saving: $12,100/year.
- RRSP transfer: Under equalization, Michael transfers $65,000 from his RRSP to Karen's via T2220. No immediate tax. Karen holds a larger RRSP for retirement.
- CPP credit splitting: Karen's CPP benefit increases by an estimated $280/month at age 65 due to Michael's contribution history during their 22 years together.
- DB pension: Michael's pension is valued at $740,000 commuted value. Karen's equalization share of $180,000 transfers to a LIRA — she can't access it freely, but it will provide meaningful LIF income in retirement.
Combined tax saving from spousal support alone over 5 years: $60,500 — all above what would have been paid with an unstructured settlement.
Working With Professionals
Income splitting after divorce in Ontario sits at the intersection of family law (Family Law Act, Divorce Act), pension law (Ontario Pension Benefits Act, FSRA), and tax law (Income Tax Act). No single professional covers all three.
The most effective team:
- A family lawyer for the legal structure of support and property division
- A Certified Divorce Financial Analyst (CDFA) to model tax outcomes and advise on asset allocation
- A tax accountant (CPA) to handle T2220 filings, T1 adjustments, and the year-of-separation return
- A financial planner for long-term retirement projections post-settlement
A common error — accepting a lump-sum spousal support payment because it sounds larger — can cost a payor $20,000–$50,000 in lost deductions over five years. The cost of professional advice is almost always recovered through better tax structuring.

Frequently Asked Questions
Q:Is spousal support tax deductible in Canada?
A:Yes — but only if it meets specific CRA conditions. Under s.60(b) of the Income Tax Act, spousal support is deductible to the payor and included in the recipient's income under s.56(1)(b). Three conditions must all be met: (1) the payment must be made to a spouse or former spouse who is living apart from you at the time; (2) the payment must be made under a written separation agreement or court order; and (3) the payments must be periodic — meaning regular installments such as monthly payments, not a single lump sum. A lump-sum spousal support payment does NOT qualify for the deduction.
Q:How does the RRSP divorce rollover work and what is Form T2220?
A:Under s.146(16) of the Income Tax Act, RRSP and RRIF assets can be transferred directly from one ex-spouse's plan to the other's plan on a tax-deferred basis. The transfer itself does not trigger income or withholding tax. Both parties must complete CRA Form T2220 (Transfer from an RRSP, RRIF, PRPP or SPP on Breakdown of Marriage or Common-law Partnership) and submit it to the financial institution — not to CRA. The transfer does not use RRSP contribution room. Errors such as withdrawing funds and writing a personal cheque trigger full taxation at marginal rates.
Q:What is CPP credit splitting and is it automatic after divorce?
A:CPP credit splitting combines the CPP contributions both spouses made during cohabitation and splits them equally. It is not automatic — either spouse must apply to Service Canada using form ISP-1901. The split permanently affects both parties' CPP entitlements. For a couple with a significant earnings gap over a long marriage, this can shift $300–$600/month in CPP benefits from the higher earner to the lower earner.
Q:Can I still use pension income splitting after a divorce?
A:Pension income splitting (s.60.03 ITA) allows up to 50% of eligible pension income to be allocated to a spouse or common-law partner. After divorce you cannot split income with your ex-spouse. However, if you remarry or enter a new common-law relationship (after 12 months of cohabitation), you can use pension income splitting with your new partner. A $60,000 pension split as $30,000 each can save $8,000–$15,000 per year depending on tax brackets.
Q:How are defined benefit pensions divided in an Ontario divorce?
A:The pension must first be valued using commuted value by an actuary. The non-member spouse then chooses: (1) a lump-sum transfer to a Locked-In Retirement Account (LIRA), which they control but cannot freely access until retirement; or (2) division at source where each spouse receives a portion when the pension member retires. Ontario's FSRA governs the process. Government pensions such as OMERS and the Ontario Teachers' Pension have their own division frameworks.
Q:What is the difference between spousal support and child support for tax purposes?
A:Spousal support is tax-deductible to the payor and taxable income to the recipient — creating a real tax shift. Child support paid under agreements dated after May 1, 1997 is neither deductible nor taxable — it is invisible to CRA. This asymmetry creates planning opportunities: a higher spousal support amount combined with lower child support can produce better after-tax outcomes for both parties depending on their respective tax brackets.
Q:Do common-law couples have the same income splitting rights after separation?
A:For CPP credit splitting, RRSP transfers, and spousal support deductibility: yes, common-law partners who lived together for at least 12 months have the same rights as married couples. For property equalization under Ontario's Family Law Act: no. Common-law partners do not automatically trigger the net family property equalization provisions — they must claim unjust enrichment or constructive trust through the courts, which is harder and more expensive.
Q:What tax planning should I do in the year of separation?
A:Key items before December 31: (1) Apply for lump-sum income averaging (s.110.2/s.120.31) if receiving retroactive support covering prior years. (2) Process RRSP transfers in the same calendar year the agreement is signed. (3) File the principal residence designation (Form T2091, Schedule 3) if transferring the family home. (4) Update your TD1 forms with your employer if support income changes your net income. (5) Update all RRSP, RRIF, TFSA, and life insurance beneficiary designations — divorce does not automatically remove an ex-spouse.
Question: Is spousal support tax deductible in Canada?
Answer: Yes — but only if it meets specific CRA conditions. Under s.60(b) of the Income Tax Act, spousal support is deductible to the payor and included in the recipient's income under s.56(1)(b).

A lump-sum spousal support payment does NOT qualify for the deduction.
Question: How does the RRSP divorce rollover work and what is Form T2220?
Answer: Under s.146(16) of the Income Tax Act, RRSP and RRIF assets can be transferred directly from one ex-spouse's plan to the other's plan on a tax-deferred basis. The transfer itself does not trigger income or withholding tax. Both parties must complete CRA Form T2220 (Transfer from an RRSP, RRIF, PRPP or SPP on Breakdown of Marriage or Common-law Partnership) and submit it to the financial institution — not to CRA. The transfer does not use RRSP contribution room. Errors such as withdrawing funds and writing a personal cheque trigger full taxation at marginal rates.

Answer: CPP credit splitting combines the CPP contributions both spouses made during cohabitation and splits them equally. It is not automatic — either spouse must apply to Service Canada using form ISP-1901. The split permanently affects both parties' CPP entitlements. For a couple with a significant earnings gap over a long marriage, this can shift $300–$600/month in CPP benefits from the higher earner to the lower earner.
Question: Can I still use pension income splitting after a divorce?
Answer: Pension income splitting (s.60.03 ITA) allows up to 50% of eligible pension income to be allocated to a spouse or common-law partner. After divorce you cannot split income with your ex-spouse. However, if you remarry or enter a new common-law relationship (after 12 months of cohabitation), you can use pension income splitting with your new partner. A $60,000 pension split as $30,000 each can save $8,000–$15,000 per year depending on tax brackets.

This asymmetry creates planning opportunities: a higher spousal support amount combined with lower child support can produce better after-tax outcomes for both parties depending on their respective tax brackets.
Question: Do common-law couples have the same income splitting rights after separation?
Answer: For CPP credit splitting, RRSP transfers, and spousal support deductibility: yes, common-law partners who lived together for at least 12 months have the same rights as married couples. For property equalization under Ontario's Family Law Act: no. Common-law partners do not automatically trigger the net family property equalization provisions — they must claim unjust enrichment or constructive trust through the courts, which is harder and more expensive.
Question: What tax planning should I do in the year of separation?
Answer: Key items before December 31: (1) Apply for lump-sum income averaging (s.110.2/s.120.31) if receiving retroactive support covering prior years.

(4) Update your TD1 forms with your employer if support income changes your net income. (5) Update all RRSP, RRIF, TFSA, and life insurance beneficiary designations — divorce does not automatically remove an ex-spouse.
