Taxes and Divorce in Canada: What Changes

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

Canada's tax system treats court-ordered or agreement-based spousal support (also called alimony or maintenance) as a transfer of income for tax purposes.

The inclusion/deduction regime

• The payer deducts periodic spousal support payments on line 22000 of their T1 return, reducing their taxable income
• The recipient includes the payments as income on line 12800 of their T1 return

This regime effectively shifts the tax burden from the higher-income payer to the lower-income recipient. Since the recipient typically has a lower marginal rate, the household's combined tax bill is reduced.

Requirements to qualify

• Payments must be periodic (regular instalments — weekly, bi-weekly, monthly)
• Made pursuant to a written agreement or court order
• Paid for the maintenance of the recipient (not a capital payment or property settlement)
• The parties must be living apart because of the breakdown of the relationship when the payment is made

What does not qualify

Lump-sum payments, payments for specific non-maintenance purposes (legal fees, one-time expenses), and informal payments without a legal agreement are not deductible by the payer and not taxable to the recipient — they are treated as capital transfers.

Child support: neither deductible nor taxable

The tax treatment of child support was changed in 1997. Under the current rules, child support is neither deductible by the payer nor included as income by the recipient. It moves from one household to the other without tax consequence.

This is a deliberate policy choice — child support is not the payer's income once paid and is not the recipient's income; it belongs to the child.

Pre-1997 agreements

Agreements entered before May 1, 1997 that were never subsequently varied may still operate under the old inclusion/deduction rules (deductible to the payer, taxable to the recipient). These are a decreasing minority of arrangements. If your agreement predates 1997, confirm with a tax professional which regime applies.

Agreements that include both types of support

Many separation agreements provide for both spousal and child support. The agreement should clearly specify which amount is for child support and which is for spousal support. If an amount is not clearly designated, CRA will generally treat it as child support (non-deductible, non-taxable), which disadvantages the payer.

Property division: generally not a taxable event

Under Section 73(1) of the Income Tax Act, transfers of capital property between spouses or common-law partners (or former spouses/partners) on relationship breakdown can be made on a tax-deferred rollover basis. The property transfers at its adjusted cost base (ACB) — the original cost — rather than at fair market value.

This means no capital gain is triggered on the transfer itself. The recipient takes the property at the original ACB and will report any gain or loss when they eventually dispose of it.

RRSP and RRIF transfers

The most common registered account transfer on divorce is the RRSP. Under Section 146(16), an RRSP can be transferred directly from one spouse's plan to the other's on relationship breakdown, without withholding tax and without affecting the recipient's contribution room. The transfer must be:

• Direct (between financial institutions — not cashed out)
• Pursuant to a written separation agreement or court order dealing with property division

The same direct transfer rules apply to RRIF accounts, deferred profit sharing plans (DPSP), and registered pension plans (RPP), each with their own specific provisions.

The family home and the Principal Residence Exemption

The family home is typically divided or one spouse buys out the other as part of a separation agreement. The PRE generally applies to shelter any capital gain on the matrimonial home, even if it is sold as part of the settlement.

Important: the year of separation still counts for PRE purposes. If you separate in 2026 and sell the home in 2026, the year 2026 can still be designated as a year of principal residence, even though you may not have lived there for the entire year after separation.

If you continue to own the matrimonial home after separation (for example, while waiting for children to finish school), the home can still qualify as your principal residence for years you had the right to occupy it — even if you are not living in it, provided you have not established another principal residence. Specific rules apply; consult a tax professional for your situation.

TFSA: no rollover provision

Unlike RRSPs, there is no equivalent rollover provision for TFSAs on relationship breakdown. Transferring a TFSA to a former spouse does not count as a TFSA contribution to the recipient — but it is also not a qualified transfer. The recipient must have their own TFSA contribution room to accept the funds, or the transfer counts as a contribution against their room.

If the recipient does not have sufficient contribution room, any over-contribution is subject to a 1% per month penalty tax. Ensure that TFSA transfers as part of a separation agreement account for the recipient's available contribution room before the transfer is made.

TFSA withdrawals to fund a transfer are not taxed, but they regenerate room only in January of the following year — not immediately. This can create a timing issue in settlement years.

Pension division

Employer pension plans (registered pension plans, or RPPs) are divided on relationship breakdown under provincial family law. Most provinces have pension division legislation:

• Ontario: Family Law Act (FLA) — pension is valued as part of net family property equalization
• BC: Pension Benefits Standards Act allows a direct transfer of a member's entitlement to the non-member spouse
• Quebec: The Supplemental Pension Plans Act governs private pension division; QPP and CPP credits can be divided through a formal application

Tax is only triggered when benefits are actually received — the division itself is not taxable. The non-member spouse who receives a pension entitlement will pay tax on those benefits when they eventually receive payments, just as the member would have.

CPP credit splitting

After separation or divorce, both spouses can apply to have their CPP pension credits earned during the relationship divided equally between them. This is called "credit splitting" and is done through Service Canada (not CRA). Credit splitting may increase or decrease each individual's future CPP retirement benefit depending on their respective contributions during the relationship.

Canada Child Benefit after separation

You must update your marital status with CRA within 11 months of the month of separation. Failure to do so means the CCB continues to be calculated on combined household income (potentially resulting in an overpayment that CRA will recover).

Shared custody

Where parents share custody of a child (each having the child at least 40% of the time), the CCB is split 50/50 between the two parents. Each parent receives half the CCB for the child based on their own household income (not combined). Both parents must apply for the CCB, and both must file their tax returns annually.

CRA determines shared custody based on the actual living arrangements, not the legal agreement. If the arrangement changes during the year, the CCB is adjusted prospectively from the following month.

Primary caregiver

If one parent is the primary caregiver (the child lives with that parent more than 60% of the time), that parent receives 100% of the CCB based on their individual household income. The other parent does not receive a CCB payment.

Updating your TD1 and withholding after separation

If you were claiming the spouse or common-law partner amount on your TD1 (line 2 of the federal TD1), this credit is no longer available after separation. You should submit a revised TD1 to your employer as soon as your status changes.

Failing to update your TD1 means your employer under-withholds tax. You will owe the difference when you file your return. Depending on the amount, this could trigger instalment requirements for the following year.

Conversely, if you now have child care expenses or other new deductions, you can ask your employer to reduce withholding by filing Form T1213 (Request to Reduce Tax Deductions at Source) with CRA and getting approval before submitting to your employer.
