Eligible dividends from a publicly-listed Canadian corporation would provide the most favourable tax treatment for Bernadette, who is in the top tax bracket. Eligible dividends are subject to a lower tax rate than other types of income because they qualify for the enhanced dividend tax credit. This credit is intended to reduce the double taxation of corporate income, which occurs when a corporation pays tax on its earnings and then distributes those earnings to its shareholders, who also pay tax on them. Dividends received from a large foreign corporation do not qualify for the dividend tax credit and are taxed at the same rate as interest income. Coupon payments from Government of Canada bonds are also fully taxable as interest income. Capital gains from a large Canadian corporation are taxed at a lower rate than interest income, but higher than eligible dividends, because only 50% of the gain is included in taxable income.
