What is T1158?
T1158, Registration of Family Support Payments, lets you register the court order or written agreement that sets out spousal and child support. Registering it helps the CRA apply the correct tax treatment, since spousal support is generally deductible and taxable while child support under agreements dated May 1997 or later is not.

Why should I register my support order?
Registering it with the CRA using the T1158 helps ensure spousal and child support are taxed under the correct rules, so deductions and income are reported properly. You attach a copy of the order or agreement to the form.
Is spousal support treated the same as child support?
No. Spousal support is generally deductible to the payer and taxable to the recipient, while child support under orders dated May 1997 or later is neither. The T1158 records both so the CRA can apply the right treatment.
