Filing Your Income Tax Return
The following pages contain everything you need to know about filing your income tax return:
When you file your return online, you get a confirmation message containing a reference number. Make sure you get one after filing.
When we receive your income tax return, we carry out a cursory review and send you a notice of assessment.
We generally have three years from the date of the notice of assessment to carry out a more in-depth review and, if necessary, issue a notice of reassessment (interest will be calculated on any balance owing at that time). You must keep all documents (paper or electronic) substantiating the information provided in your return (RL slips, information slips, receipts and supporting documents), as we may ask for them if such a review is carried out.
