Is Child or Spousal Support Taxable in Canada?

Generally, periodic spousal support paid under a court order or written agreement is deductible for the payer and taxable for the recipient, while child support under an order or agreement made after April 1997 is neither deductible nor taxable. Lump sums and informal payments usually fall outside the deduction. The details are in the federal Income Tax Act.

How support is taxed in Canada, step by step

Tax treatment can change the real cost of support by thousands of dollars a year, which is why family lawyers and the federal advisory guidelines work with after-tax numbers. This page explains the rules in the Income Tax Act that decide whether a payment counts, in plain terms. It is general information, not tax advice; an accountant should confirm how it applies to your return. For the wider picture of support, see our child and spousal support page.

To work out whether a payment is deductible and taxable, ask these questions in order:

Is it a "support amount"? The Act defines it as an amount payable or receivable as an allowance on a periodic basis for the maintenance of the recipient, the recipient's children or both, where the recipient has discretion as to how the money is used (s. 56.1(4)).
Is there an order or written agreement? For a spouse or former spouse (including a common-law partner), the parties must be living separate and apart because of the breakdown of the relationship, and the amount must be receivable under a court order or a written agreement. For a parent who was never a spouse, it must be under a court order made under provincial law.
Is any of it child support? A "child support amount" is any support amount not identified in the order or agreement as being solely for the support of the spouse or former spouse (s. 56.1(4)). That definition matters: unlabelled support is treated as child support.
When was the order or agreement made? For child support, what matters is the "commencement day": for an order or agreement made after April 1997, the day it is made (s. 56.1(4)). Child support payable under it on or after that day is excluded from the payer's deduction (s. 60(b)).
Apply the formula. The payer's deduction is, broadly, support amounts paid while living separate and apart, minus child support amounts that became payable after the commencement day, minus amounts already deducted in an earlier year (s. 60(b)).

Child and spousal support compared

Type of payment	Payer	Recipient	Why
Periodic spousal support under an order or written agreement	Generally deductible	Generally taxable	It is a "support amount" that is not child support (ss. 56(1)(b), 60(b))
Child support under an order or agreement made after April 1997	Not deductible	Not taxable	Child support payable after the commencement day is taken out of the formula
Support not labelled as spousal only	Treated as child support	Treated as child support	Definition of "child support amount" (s. 56.1(4))
Lump sum payment	Usually not deductible	Usually not taxable	Not an allowance "on a periodic basis"
Payments with no order or written agreement	Not deductible	Not taxable	The definition requires an order or written agreement
Third-party payments (for example, rent or tuition paid directly)	Can be deductible if the order or agreement says ss. 56.1(2) and 60.1(2) apply	Taxable on the same basis	Deemed periodic allowance when the order or agreement provides for it

Payments made before the agreement or order is signed

Separated spouses often start paying support before anything is in writing. The Income Tax Act allows those payments to count if the later written agreement or order says so. If an agreement or order made in a tax year provides that amounts paid earlier in that year or the preceding year are to be considered paid under it, those amounts are deemed to have been paid under it (ss. 56.1(3) and 60.1(3)).

So timing matters. If one spouse paid monthly spousal support from June and the separation agreement is signed the following March with the right clause, the earlier payments can be brought within it. Without that clause, or if the payments started more than a year before the year of signing, they may not qualify.

What changes the answer

Labelling. Because support not identified as solely spousal is treated as child support, an agreement should state clearly how much is spousal support and how much is child support.
Periodic or lump sum. Periodic payments can be deductible; a lump sum generally cannot. Converting future spousal support to a lump sum has a tax cost or benefit for each side; see how long spousal support lasts.
Discretion over use. The recipient must have discretion as to the use of the money, unless the third-party rules in ss. 56.1(2) and 60.1(2) apply because the order or agreement says so.
Living separate and apart. The payer's deduction requires that the spouses were living separate and apart when the amount was paid (s. 60(b)).
Child care and special expenses. Under the child support guidelines, section 7 expenses are shared after taking into account tax deductions and credits relating to the expense; see special or extraordinary expenses.
Pensions. Dividing a pension as property is separate from support and has its own tax rules; see how pensions are divided on separation.

How tax affects the support calculation

Because spousal support moves taxable income from the payer to the recipient, the after-tax cost to the payer is lower than the cheque, and the after-tax value to the recipient is lower too. The with child support formula in the federal advisory guidelines works directly on net incomes for that reason; see how the amount of spousal support is worked out. Child support under a post-April 1997 order or agreement, by contrast, is neither deducted nor taxed, so the table amount is what both sides actually pay and receive; see how child support is calculated.

Income for support purposes also has its own rules, separate from taxable income. For example, the child support guidelines deduct spousal support received from the recipient's income for the table, and deduct spousal support paid from the payer's income for sharing special expenses; see what counts as income for support.

A worked example

For example, imagine a separation agreement signed in Toronto in 2026 that requires one parent to pay $1,500 a month in child support and $1,000 a month in spousal support, with each amount clearly labelled, and a clause saying that payments made since July of the previous year count under the agreement.

For tax purposes, the $1,500 of child support is neither deductible nor taxable. The $1,000 of spousal support is periodic, payable under a written agreement, and labelled as spousal support, so the payer can generally deduct $12,000 a year and the recipient includes $12,000 in income. The spousal support paid from July of the previous year can also count, because of the prior-payments clause. If the agreement had simply said "$2,500 a month in support", the whole amount would be treated as child support, and the payer would lose the deduction. This example is hypothetical and simplified; individual returns depend on other factors.

Common mistakes with support and taxes

Not separating child and spousal support in the agreement. Unlabelled support is treated as child support.
Paying informally for months without a written agreement. Without an order or written agreement, payments are not deductible, and only payments in the year of signing or the year before can be brought in.
Agreeing to a lump sum without checking tax. The payer may lose a deduction, and the recipient may avoid tax, which changes the fair number.
Paying third parties without the right clause. Paying a mortgage or tuition directly is only treated as support if the order or agreement provides for it.
Forgetting that the recipient owes tax. Recipients of spousal support should plan for the tax on it, for example by setting money aside.
Treating arrears payments casually. Missed payments still owe; see what happens if support is not paid.

What to do this week

Write down every support payment made since separation, with dates, amounts and method.
Check whether there is an order or a signed written agreement covering those payments.
If an agreement is being drafted, make sure it labels child support and spousal support separately.
Ask whether earlier payments should be covered by a prior-payments clause.
Talk to your accountant about how the payments will be reported on your return.

Frequently asked questions

Is child support ever deductible?

For orders and agreements made after April 1997, child support is generally not deductible and not taxable. Older arrangements can have different treatment, depending on their commencement day.

Does a verbal agreement count?

No. The definition requires a court order or a written agreement for spouses, and a court order for parents who were never spouses.

Is spousal support paid to a common-law partner deductible?

Yes, on the same basis as for married spouses, because the definition includes a common-law partner or former common-law partner; see who is entitled to spousal support.

What about legal fees?

Tax treatment of legal fees is outside the support provisions discussed here. Ask your accountant before claiming anything.

If I pay the mortgage on the home my former spouse lives in, is that support?

It can be, if the order or written agreement provides that subsections 56.1(2) and 60.1(2) apply. There are limits for amounts relating to acquiring or improving a home, so the wording needs care.

Do these rules change if support is varied?

A variation can create a new commencement day for child support, which matters mainly for older orders. For spousal support, the same definitions apply to the varied order; see changing spousal support.

Can we agree that spousal support will not be deductible?

Tax treatment follows the Income Tax Act definitions, not labels the parties choose. Spouses can, however, structure support so it falls inside or outside the definitions, for example by choosing a lump sum instead of periodic payments, and should price that choice into the deal.

What if the paying spouse lives outside Canada?

Cross-border cases raise tax questions under more than one country's law. The Canadian definitions above still decide the Canadian treatment, but get advice from an accountant familiar with both systems before signing.
