A new taxation year for Canadian income tax purposes is deemed to have started when a change in control of a corporation takes place. If your corporation is about to undergo a change in control it will shorten the carry-forward period of your unused losses and cause their expiry. It may be possible to devise a mutually beneficial tax plan with the purchaser by billing before the sale for services to be rendered after the change in control in order to generate income to absorb the unused losses before they expire.
