Direct deposit

If you find yourself with a credit (negative balance) in your student account, McMaster will first verify, then refund the over payment.

For a quick, safe and easy way to receive a refund, we strongly encourage enrolling in direct deposit. By entering your personal bank account information, funds will be transferred electronically back to your personal bank account. The alternative is to wait for a cheque to be cut and mailed out.

Please note: Refunds are generally scheduled for February of each year (after the winter term drop/add period is over and all courses finalized). There are certain circumstances where we would accept a refund request mid-session (i.e. a withdraw, over payment in error, etc.). Requests will be accepted by email to

In the subject line, please type REFUND, your name and 9-digit ID number. i.e. Subject: REFUND – John Smith #00111111

Before enrolling in direct deposit

The most important thing you need in order to begin is your correct banking information. DO NOT enter the number on your bank card.

Your correct banking information can be found at the bottom of any cheque belonging to the account you want your payment deposited. Example below (from the bottom of the cheque).

  1. The first three numbers are the cheque number (not required for this enrolment).

  2. The next five numbers are the transit number (branch number).

  3. The next three numbers are the financial institution number (bank code).

  4. The remaining numbers are your bank account number.

If you don’t have cheques, this information is available by contacting your bank directly. Many banks provide this information online, under the secured account information section.

Once you have your correct banking information, visit your Mosaic Portal to enrol.

Your SIN has not generated on your TAX documents as your student profile was not updated on Mosaic in time. Students are still able to file their taxes with the documents as they are still valid without the SIN. Please update your SIN on Mosaic by bringing your SIN in person in the student services office or through Mosaic.

To update your SIN through Mosaic: You can use the “Update SIN (Student)” tile, or via the Student Centre. To update your SIN via the Student Centre, click Demographic Data under Personal Information. Enter your SIN, without spaces, and click Save.
