As per the Canada Revenue Agency, if you are eligible to Netfile, the TurboTax software will send all forms necessary to the Canada Revenue Agency (CRA). Please keep all your receipts for proof should the CRA request them at a future date.
Annually, you need to complete the T1 General Income Tax and Benefit Return as well as associated territorial or provincial forms. In order to complete your return, you also will likely need to complete schedules or additional forms that request more information. Schedules should be attached to your income tax return in most cases if you mail them in.
For example, if you split pension income with your spouse, the CRA requires you to complete and submit form T1032. In most cases, you need to attach these forms to your income tax return when you file it, and you should make copies for your records.
However, in cases where a form establishes a long-lasting condition, you typically do not have to file it each year.
