Corporation income tax return

Corporations with more than $1 million in gross revenue are required to file their income tax returns online. Failure to do so generally renders them liable to a $1,000 penalty.

Note that this requirement does not apply to the following corporations:

• insurance corporations;
• non-resident corporations; 
• corporations that file their income tax returns in a functional currency; 
• corporations that are tax-exempt under Book VIII of Part I of the Taxation Act.
