Tax on Separation and Divorce

When a marriage or common-law relationship ends, the parties are usually focused on the family law questions: who pays support, how property is divided, and what happens to the home. Running alongside every one of those decisions is a set of tax consequences under the Income Tax Act, and those consequences do not always line up with intuition. Support that the parties think of as one undivided obligation is split by the Act into deductible and non-deductible halves; a transfer of property that feels like it should be neutral can trigger a capital gain; and the way a separation agreement is worded can change who pays tax on what for years to come.

This page sets out, in general terms, how Canadian federal tax law treats the main financial events of a separation or divorce: spousal and child support, the rollover of capital property between spouses, the cessation of income attribution, the family home, equalization payments, the transfer of RRSPs and registered plans, and pension income splitting. It is general information, not legal or tax advice, and the right answer in any case depends on the facts and on the precise wording of the agreement or court order.

Spousal support: deductible to the payer, taxable to the recipient

The Act treats periodic spousal support very differently from a lump-sum property settlement. Under the support rules, a support amount that meets the statutory definition is deductible to the payer and included in the income of the recipient. The payer claims the deduction under the support-payment provisions of the Act, and the recipient reports the same amount as income, so the obligation effectively shifts the tax on those dollars from the payer to the recipient.

The deduction and inclusion are not automatic. To qualify as a deductible and taxable support amount, the payment generally must satisfy each of the following: it must be payable on a periodic basis for the maintenance of the recipient (or of children, discussed below); the recipient must have discretion as to its use; the parties must be living separate and apart because of the breakdown of their relationship; and the amount must be payable under a written separation agreement or a court order. A purely verbal arrangement, or money moved between accounts with no written agreement or order behind it, does not produce the deduction.

The periodic requirement is critical. A lump-sum payment made to settle support or to divide property is generally neither deductible to the payer nor taxable to the recipient, because it is not a periodic allowance. This is a common area of misunderstanding and a planning point: whether support is structured as a stream of periodic payments or as a single capital sum changes the tax outcome substantially, so the family law and tax considerations should be weighed together. Because the recipient pays tax on periodic spousal support, the after-tax value of a given dollar figure is not the same for both sides, and a well-drafted agreement accounts for that.

Child support under post-1997 agreements is tax-neutral

For most families today, child support is neither deductible to the payer nor taxable to the recipient. This was not always the case. Before the rules changed in 1997, child support followed the same deduction-and-inclusion model as spousal support. The reform replaced that model with a tax-neutral one tied to a concept the Act calls the commencement day of an agreement or order.

In broad terms, if a separation agreement or court order has a commencement day of May 1, 1997 or later, the child support payable under it is not deductible by the payer and not included in the recipient's income. Older orders made before that date could continue under the former rules until a commencement day was triggered, for example by a new agreement or order or by electing into the new regime. Because most agreements now in force post-date the reform, child support is, for most people, simply tax-neutral.

The interaction between child support and spousal support is where many reassessments arise. The Act contains an ordering rule: where an agreement or order requires both and the payer does not pay the full amount owing, payments are applied first to child support. Because child support is tax-neutral, a payer in arrears cannot claim a deduction for spousal support until the child support owing for the period has been fully paid. Equally, support is only deductible to the extent the agreement or order clearly identifies a separate, periodic spousal-support amount; if the document lumps everything together as undifferentiated "support" for a spouse and children, the CRA may treat the entire amount as non-deductible child support. Precise drafting is what preserves the deduction.

The 73(1) tax-deferred rollover of capital property

Dividing the family's property would, on its face, mean disposing of capital assets, and a disposition normally triggers a capital gain or loss measured against the asset's cost. The Act softens this through an automatic rollover. Under subsection 73(1), capital property transferred between spouses or common-law partners (including a transfer to a former spouse or common-law partner in settlement of rights arising out of their marriage or partnership) is generally deemed to be transferred at its adjusted cost base rather than at fair market value, so that no capital gain or loss arises on the transfer. The recipient takes the property at the transferor's cost, and the accrued gain is deferred, not eliminated.

The rollover is the default rule, but it can be elected out of. In some situations the transferor may prefer the transfer to occur at fair market value, for example to use available capital losses or, in the right circumstances, the lifetime capital gains exemption on qualifying property. Electing out of the rollover crystallizes the gain on transfer; leaving the rollover in place defers it to the recipient. Which is preferable depends on each party's tax position, the nature of the asset, and the structure of the overall settlement, and it is a decision that should be made deliberately rather than by accident.

The rollover defers tax to whoever ends up holding the property. A spouse who receives a non-registered investment portfolio or a rental property at the transferor's low cost base will face the full accrued gain when they later sell. Two settlements that look equal on paper can therefore be very different after tax, because one party may be receiving assets that carry a built-in tax liability while the other receives cash or registered funds that do not. Valuing what each side actually keeps on an after-tax basis is part of getting the division right, and it overlaps with broader capital gains tax planning.

A separation also changes how the attribution rules operate. While spouses are together, those rules can tax one spouse on income or gains earned on property transferred or loaned to the other. Under subsection 74.5(3) of the Act, the attribution of income stops applying while the spouses or common-law partners are living separate and apart because of the breakdown of their relationship, so the income on previously transferred property is taxed to the spouse who actually owns and earns it. For attribution of capital gains, the parties can jointly elect for the gains-attribution rule to cease to apply while they are living separate and apart. This is one of the few tax features of separation that generally works in the parties' favour, but it depends on their genuinely living separate and apart due to the breakdown, which is a question of fact.

The family home and the principal residence exemption

The matrimonial home is usually a family's largest asset, and how it is treated after separation has real tax consequences. While the parties are together, a family unit can designate only one property as a principal residence for any given year. Once the spouses are living separate and apart throughout a year because of a relationship breakdown, they are no longer treated as a single family unit for this purpose for that year, which can allow each former spouse to designate a separate property, such as one keeping the city home and the other a cottage, for years after the separation.

Several issues commonly arise. If one spouse moves out and the other remains, the home can usually still qualify for the exemption during the relevant period, but the analysis turns on ownership, occupancy, and the terms of the settlement. If the home is transferred between spouses as part of the division of property, the subsection 73(1) rollover described above generally applies, and the exemption rules then govern any later sale. And if the home is retained and later rented out, a change of use can arise, with its own deemed-disposition consequences. Each of these points is fact-specific and interacts with the detailed rules under the principal residence exemption. Care should be taken so that, between two former spouses and possibly two properties, the designation years are allocated correctly and the exemption is not inadvertently lost or doubled up.

Equalization payments and dividing property

Provincial family law generally requires an equalization or division of family property when a marriage ends, often resulting in one spouse making a payment to the other to equalize their respective shares. An equalization payment of cash is generally not itself a taxable event: paying or receiving a cash equalization amount is a division of capital, not income, so the recipient does not include it in income and the payer cannot deduct it.

The tax consequences live in what is transferred to satisfy the equalization, not in the equalization figure itself. Transferring capital property, such as investments, real estate, or shares of a private company, ordinarily engages the subsection 73(1) rollover and defers the accrued gain to the recipient. Transferring registered funds engages the RRSP and pension rules discussed below, while satisfying the obligation with cash generally has no immediate tax effect. The same dollar amount of equalization can therefore carry very different latent tax depending on which assets are used to pay it, which is why each asset class needs to be valued on an after-tax basis. Dividing the shares of a private corporation raises further questions around how value is extracted and which corporate accounts are affected, matters that connect to business owner tax planning.

RRSPs, pensions and registered plans

Registered savings can usually be divided without triggering tax, but only if it is done correctly. Under subsection 146(16) of the Act, an amount can be transferred directly from one spouse's or former spouse's RRSP to the other's RRSP (or RRIF) on a tax-deferred basis where the transfer is made under a written separation agreement or a court order relating to a division of property on the breakdown of the relationship, and the parties are living separate and apart at the time. Done this way, the transfer is not income to the recipient and not a withdrawal taxed to the transferor; the funds simply move from one registered plan to another and remain tax-deferred.

The mechanism matters enormously. If, instead of a direct plan-to-plan transfer, one spouse simply withdraws cash from their RRSP and hands it over, that withdrawal is fully taxable to the spouse who withdrew it, and the funds lose their registered status. A division that should have been tax-neutral can become a large, immediate tax bill purely because of how the money moved. Similar direct-transfer rules apply on the breakdown of a relationship to Registered Pension Plan entitlements and, in defined circumstances, to Tax-Free Savings Accounts, where a TFSA transfer between former spouses under a court order or separation agreement can be made without affecting either party's contribution room. As with the RRSP rules, the relief depends on the transfer being made properly under a qualifying agreement or order.

Pension income splitting and credits after separation

Some tax measures designed for couples change or fall away on separation, and timing becomes important. Pension income splitting allows a pensioner to jointly elect with a spouse or common-law partner to allocate a portion of eligible pension income to the lower-income partner, reducing the couple's combined tax. That election is only available to spouses or common-law partners, and it generally cannot be made for a year if, by reason of the breakdown of the relationship, the parties were living separate and apart at the end of the year and for a period of at least 90 days beginning in the year. In the year of separation, then, the ability to split pension income can be lost, which affects how the final year of the relationship is reported.

Other couple-based items shift as well. The spousal amount and the eligible dependant credit each have conditions tied to marital status and support, the rules for claiming children change once support is being paid, and a person cannot generally claim certain amounts for a spouse for whom they are also deducting support. These items need to be reviewed for the year of separation and the years that follow, and because they are exactly the sort of thing the CRA reviews, consistency between the two former spouses' returns is important. Where the broader financial reorganization continues after the split, it often dovetails with ongoing tax planning for each individual going forward.

How Barrett Tax Law approaches this

When we are asked about the tax side of a separation or divorce, we start with the documents and the facts: the separation agreement or court order, what is being paid and how, what property is being divided, and which assets carry accrued gains or sit inside registered plans. From there we work through the provisions that govern each piece, the support-payment rules, the subsection 73(1) rollover, the cessation of attribution under subsection 74.5(3), the principal residence rules, the registered-plan transfer rules in subsection 146(16) and its counterparts, and the pension-splitting and credit rules, so that the agreement does what the parties intend and the returns are filed consistently with it.

Often the work is about wording before anything is signed: making sure spousal support is structured and described so that a deduction the parties are counting on is actually available, and that property and registered funds move in a way that does not create an avoidable tax bill. Where a CRA reassessment has already arisen, for example a denied support deduction, a disputed RRSP transfer, or a principal residence question, we review the basis of the assessment and the available avenues to respond, which may include a notice of objection under our work on tax disputes and objections and, if necessary, an appeal to the Tax Court of Canada.
