My bank statement had one incoming transfer. Our agreement had two amounts. I nearly copied the whole deposit into the income box because it looked like the simplest number to use.
The monthly transfer was $1,300: $900 for our child and $400 for me. The tax treatment depended on those purposes and the agreement, not on the fact that the money arrived together.
Start with the agreement and the type of payment
For a qualifying order or written agreement made after April 1997, child support is generally neither deductible by the payer nor taxable to the recipient. Qualifying spousal support is generally deductible and taxable respectively. An amount not identified as solely for the recipient's support is generally treated as child support under these rules. CRA's child and spousal support rules.
Calling a transfer “support” is not enough. The federal definition generally requires a court order or written agreement, periodic maintenance payments, the required relationship between the parties and the recipient's discretion over the allowance. Special rules apply to some third-party payments, retroactive arrangements and lump sums. A property settlement is not automatically deductible spousal support. Definition and exceptions.
Reconcile the total and the taxable portion
Suppose my agreement began before the year, all payments were made for 12 months and no child-support arrears exist. The spousal component meets the tax conditions.
| Annual amount | Calculation |
|---|---|
| Child support | $900 × 12 = $10,800 |
| Spousal support | $400 × 12 = $4,800 |
| Total received and paid | $15,600 |
I report $15,600 at line 12799 and the $4,800 taxable portion at line 12800. The payer reports $15,600 at line 21999, with $4,800 as the deductible amount at line 22000. Those paired lines serve different purposes; the total is not itself the taxable or deductible amount. Receiving support, paying support.
Use what actually happened during the year, supported by the agreement and payment record. Multiplying the scheduled monthly amount by twelve is not a substitute for checking missed or partial payments.
Check unpaid child support before claiming a deduction
Where child and spousal support are payable to the same recipient, the child-support priority rule matters. Current and prior-year child support must be fully paid before the payer can deduct spousal support. Merely labelling a transfer “spousal” does not bypass arrears.
Do not assume the recipient's result mirrors a denied deduction. The CRA's example requires the recipient to report spousal payments actually received even when the payer cannot deduct them because child support remains unpaid. The rules have an exception for different recipients under different orders or agreements. Priority rule and example.
Keep the documents together
Retain the order or signed agreement, changes, payment confirmations and an annual reconciliation. Check the CRA registration requirements when support is deductible or taxable. Orders made before May 1997, changes to those orders and one-time settlements need their own review.
My useful working document was a short list of dates, amounts and purposes. One bank transfer could stay one bank transfer. It did not need to become one tax category.
Checked October 20, 2026. Federal income-tax treatment; determining or changing a legal support obligation is a separate matter.
