Information for Our Partners – Corporation Income Tax

Partners that develop products for the Corporation income tax field of activity can develop or adapt products to be used by corporations to fulfill their fiscal obligations electronically.

More specifically, corporations must be able to use the products partners develop or adapt to:

  • file their corporation income tax returns;
  • pay an income tax balance due;
  • make instalment payments.

More information on corporation income tax is available under Income Tax in the Businesses section.


We receive approximately 500,000 corporation income tax returns every year, 92% of which are prepared using authorized software. Most of these returns are transmitted online by corporations or tax preparers.
