CRA confirms that its rulings for the multiplication of the small business deduction by professionals’ service corps will cease to apply

The 2016 Budget will extend the specified partnership income rules to the structures in which the CCPCs of professionals or their family provide services to a partnership of which the professional is a member (and there is a comparable proposal for private corporate structures). Needless to say (but someone asked anyway):

With respect to any advance income tax rulings involving such partnership reorganization structures…any advance income tax rulings issued by the CRA will cease to bind the CRA on the coming into force of the proposed legislation.
