We issue a notice of assessment for every income tax return you file. Notices are generally mailed out, unless you specifically ask to receive yours online. They are also available online in My Account at any time, even if you filed your return by mail.

We start processing returns in March and generally issue a notice of assessment within 14 days for a return filed online or 28 days for a return filed by mail.

Viewing your notice of assessment online

You can view your recent notices of assessment online at any time in My Account for individuals. This is the fastest way to find your notice of assessment number if you can't find the paper version.
