Ontario corporate minimum tax loss carryforward

A corporate minimum tax loss may be carried forward 20 years.


Upon amalgamation under section 87 of the federal Income Tax Act, only corporate minimum tax losses from predecessors who are not controlled by predecessors in the amalgamated group can be transferred to a new corporation. On a vertical amalgamation of a parent and subsidiary corporations, only the loss from the parent may be transferred to the new corporation. The subsidiary's loss may not be transferred to the parent.


Upon winding-up a subsidiary under subsection 88(1), the subsidiary's corporate minimum tax loss may not be transferred to a parent corporation.

Calculate the carry-forward amount in Part 7 of Schedule 510, Ontario Corporate Minimum Tax.
