Income tax – Corporations
If two or more taxable Canadian corporations amalgamate, the registration number of one of the predecessor corporations can be kept, or a new registration number can be assigned to the new corporation.
The corporation resulting from the amalgamation is considered a new corporation whose first taxation year begins on the date of the amalgamation. As a result, you can choose the end date of the new corporation's taxation year, provided the taxation year does not exceed 53 weeks. The taxation years of the predecessor corporations end immediately before the amalgamation.
Numerous aspects of the predecessor corporations have an impact on the new corporation, such as inventory, depreciable property, contracts, losses and fiscal elections.
