Divorce and separation tax in Canada: a CPD course for CPAsGet the tax right
before the agreement is signed.
Spousal support deductibility, the spousal rollover and the principal residence designation are decided by the separation agreement. Learn the conditions, the 90-day rules and the drafting that keeps a property split tax-free.
Most Separation Files Reach the Accountant After the Agreement Is Signed
Roughly 40% of relationships in Canada end in separation or divorce, and each one has two parties who need tax advice.
By the time the file reaches you, the deductibility of support, the rollover of the house and the treatment of the company shares are usually already locked in by the wording of the agreement.
The calendar decides much of the rest: 12 months to form a common-law partnership, 90 days to end one.
The 90 days must be continuous and caused by a breakdown of the relationship. Couples can live separate and apart under the same roof.

One Missing Agreement, Two Taxable Outcomes
A married couple separates in 2016 without a written agreement. One keeps the house, the other buys a condo, and both sell in 2024. Spouses share one principal residence designation until divorce, so whoever designates first takes the exemption.

What the Seminar Covers
One two-hour recording that works through six topics in the order they arise on a file, from the date of separation to the credits and benefits that close it out.
Topic 1Date of Separation, Common-Law Status and the Conflict of Interest
Date of Separation, Common-Law Status and the Conflict of Interest
- Why acting for the family becomes a conflict on separation, and what the CPA Code requires to continue an engagement.
- Spouse versus common-law partner: the 12-month cohabitation test, the parent-of-a-child alternative, and the deeming rule that keeps a partnership alive after the split.
- The “separate and apart” test and the conjugal-relationship factors, including couples living apart under one roof.
- The 90-day rule, a reconciliation that resets the 12-month clock, and why living apart for other reasons does not count.
- Forms T1158 and RC65, and how the separation date drives support, rollovers, attribution and principal residence claims.
Topic 2Spousal Support Deductibility: The Six Conditions
Spousal Support Deductibility: The Six Conditions
- Child versus spousal support, pre-May 1997 agreements, and when deductibility is actually desirable.
- What counts as a written agreement or court order, including solicitors’ correspondence, and why email exchanges likely fall short.
- The test for an “allowance”, and the drafting failure that turns a global payment into non-deductible child support.
- The periodic-payment factors, when a lump sum still qualifies, and retroactive averaging on Form T1198.
- Prior payments validated under 56.1(3) and 60.1(3), and the one-year look-back limit.
Topic 3Third-Party Payments, Ordering Rules and Non-Resident Support
Third-Party Payments, Ordering Rules and Non-Resident Support
- The general rule in 60.1(1) and the specific rule in 60.1(2) and 56.1(2), and why the agreement should cite the subsections.
- The limits: medical, educational and residence expenses, and the cap of one fifth of the original mortgage principal.
- Why a car loan fails, mortgage payments succeed, and rent is deductible while school fees are not.
- The ordering rule that applies payments to non-deductible child support arrears first, worked through the 60(b) formula.
- Cross-border support: treaty relief, no Part XIII withholding, and registration of agreements on Form T1158.
Topic 4The Spousal Rollover, Principal Residence and Registered Plans
The Spousal Rollover, Principal Residence and Registered Plans
- The automatic 73(1) rollover, the property-by-property election out, and using capital losses that would otherwise be wasted.
- The one-designation-per-couple rule, the written-agreement requirement, and why the first spouse to designate gets the exemption.
- Subsection 40(4) on a rollover, and the flipped-property exclusion for relationship breakdown.
- RRSP, RRIF and FHSA transfers on breakdown, and the spousal RRSP attribution rule that switches off on separation.
- CPP credit splitting: the application, the exclusions, and why combined pensions after a split are often lower.
Topic 5Attribution Rules and Splitting a Private Company
Attribution Rules and Splitting a Private Company
- Why income attribution stops on separation but capital gains attribution continues until a joint election is filed, or until divorce.
- Buying out a spouse through the shareholder loan account, and tax-efficient distributions before a reorganization.
- A $2,000,000 company worked in full: the agreed value of $1,800,000, the section 85 transfer to a new company and the redemption.
- Why the parties should stay married through the reorganization, and how common-law partners lose the related-party exception after 90 days.
- The related-party butterfly across a corporate group, and trust distributions on separation.
Topic 6Legal Fees, Credits, Benefits and Equalization
Legal Fees, Credits, Benefits and Equalization
- Which legal and accounting fees are deductible, and the asymmetry between the recipient and the payor.
- The eligible dependant credit, child care expenses under joint custody, and the Canada Child Benefit reset.
- Tax discounts on equalization: comparing assets with different embedded tax on a like-for-like basis.
- How a routine indemnity clause can create reportable-transaction exposure for both parties and their advisors.

Common Questions
What are the tax implications of divorce or separation in Canada?
The main ones are whether spousal support is deductible and taxable, whether property moves between spouses at tax cost under the spousal rollover, how each spouse can claim the principal residence exemption, when the attribution rules stop applying, and how registered plans, CPP credits, credits and benefits are divided. Most of these outcomes are set by the wording and timing of the separation agreement.
Is spousal support tax deductible in Canada?
Generally yes, and it is taxable to the recipient, if it is paid under a court order or written agreement, payable on a periodic basis as an allowance the recipient can use at their discretion, paid while the parties live separate and apart because of a breakdown of the relationship, and the agreement is registered with the CRA on Form T1158.
Is child support taxable or deductible in Canada?
No. Child support is neither deductible to the payor nor taxable to the recipient, unless it is paid under an agreement or order made before May 1, 1997 that has not been varied since. Where a payment mixes child and spousal support without separating them, the CRA treats the whole amount as child support.
When are a couple considered separated for tax purposes?
A common-law partnership ends once the partners have lived separate and apart for 90 consecutive days because of a breakdown of the relationship. They can be separate and apart while living under the same roof. A marriage ends for tax purposes only on divorce, although separation still affects support, attribution and other rules.
Can each spouse claim a principal residence after separation?
A married couple can designate only one principal residence per year. After separation, each spouse can designate their own home for later years only if they are separated under a written separation agreement or court order. Without one, the first spouse to designate generally takes the exemption for the shared years.
How is property transferred between spouses on separation taxed?
Capital property transferred to a spouse or former spouse in settlement of rights arising from the relationship rolls over automatically at its tax cost under subsection 73(1), so no gain is triggered. The transferor can elect out property by property, for example to transfer an asset at fair market value and use capital losses that would otherwise go unused.
