Although you don’t need to submit the transit pass when you are filing your tax return, you should keep your supporting documents in case you are audited.
To support your claim of public transit tax credit, your transit passes have to display all of the required information such as an indication that it is a monthly (or longer duration) pass, the name of the transit authority, the amount, and the identity of the rider (name or unique identifier).
If your pass does not have all of this information, you will also need to keep receipts, cancelled cheques or credit card statements, along with your pass, to support your claim.
