Why is my spouses SIN required?

Thank you for choosing TurboTax,

Each Canadian files their own tax return and indicates their marital status on the return, and who they are married to / living with.

You do not get to decide whether to claim your marital status on your tax return.  Once you are married, you must include your spouse.  Therefore,  you must note your status as in the “information about you” section of your tax return, including information about your spouse – their name, social insurance number, net income, and employment status.

 

Please visit our TurboTax article on Facts Every Canadian Needs to Know About Filing Coupled Tax Returns and What do I do if I don’t know my spouse’s income?  learn more about why you need to have your spouse's SIN number.
