Commission Tax Method
For the Commission Tax Method to work as designed, the Commission group boxes must be completed on the Quebec Income Tax Data page.
If the Commission group boxes are not completed, the tax calculation process defaults to the Annualized Tax Method.
The following outlines the method that is used in calculating CIT (federal and provincial excluding Quebec) and QIT using the commission tax method.
Note:
Any payment that uses the commission tax method is referred to as a "commission payment" for the purpose of this documentation.
