31c. I haven’t filed my taxes for previous years, how can I file these tax returns?
As long as you have filed a tax return in the past with the CRA and we have the correct information on file for you, for example, your correct address, depending on the software product you use, you may be able to file returns for tax years 2017 and after using
certified tax software. If the CRA does not have your current information, please update it before you file.
If you are filing returns from before 2017, you will need to file paper returns. These returns can be found on our
tax packages for all years web page.
To avoid delays in receiving your notice of assessment or it going to the wrong address, we encourage you to update your personal information at the CRA before you try to file.
You can file a return as far back as ten years. We recommend that you file the oldest return first to take advantage of carry-over amounts that may be available from the previous year.
The CRA will charge you a late-filing penalty if you file your 2021 tax return after the due date and you owe tax that remains unpaid at that time.
