Immediate expensing for small CCPCs

Canadian-Controlled Private Corporations (CCPCs) can use the immediate expensing incentive to deduct up to $1.5 million of eligible depreciable property in the year of acquisition — instead of claiming CCA over multiple years. Eligible property includes Class 50 computers, Class 10 vehicles, office equipment, and most other CCA classes (Class 1 buildings and goodwill are excluded). This was introduced as a temporary measure but has been extended; check the current CRA guidance for the applicable tax years. Sole proprietors and partnerships of individuals also qualify, with a combined limit shared among associated businesses.
