How to Fill out a TD1 Form (2021)


Your employer is required by law to ask you for some information about your particular tax situation, and that’s why they have asked you to complete a TD1 form. 

It is also known as the 2021 Personal Tax Credits and Return, and is requested when you begin your new employment.

Employers are required to keep this form on file, because when they get audited by Canada Revenue Agency, they need to be able to prove that they have withheld the proper amount of source deductions; that’s the income tax in the CPP and the employment insurance premiums at source. 

There is a federal (TD1) and provincial (TD1ON) version and you can access the form here

Please note: This article covers information pertaining only to the federal TD1 version.
