Final answer:
A QSBC must be a CCPC using at least 50% of its asset value for active business in Canada when shares are sold.
Step-by-step explanation:
One of the requirements for a business to qualify as a qualified small business corporation (QSBC) is that the corporation must be a Canadian-controlled private corporation (CCPC) that uses at least 50% of the fair market value of its assets for active business purposes in Canada at the time the shares are sold. This requirement seeks to ensure that the benefits provided to a QSBC, like certain tax advantages, are directed towards small to mid-sized businesses actively engaged in the Canadian economy.
