Corporations

Most corporations can file their T2 Corporation Income Tax Return electronically using the Internet. It is mandatory for certain corporations with annual gross revenues that exceed $1 million.

This $1 million threshold is eliminated for tax years starting after 2023. Most corporations will have to file their return electronically.
