Bernadette has a high-paying job and is in the top tax bracket. She recently received a payment of $5 million upon the settlement of her uncle’s estate. Bernadette would like to invest her inheritance in financial products that would not only grow her money but is also income tax friendly. Which of the following would provide the most favourable tax treatment?

For an individual in the highest tax bracket, capital gains receive the most favourable tax treatment. In Canada, only 50% of a capital gain is included in taxable income (the "inclusion rate"). This means the effective tax rate on capital gains is half the investor's marginal tax rate. While eligible Canadian dividends also receive preferential treatment through the dividend tax credit, the effective tax rate is typically higher than that for capital gains, especially for high-income earners. Interest income and foreign dividends are fully taxable at the investor's marginal tax rate, making them the least tax-efficient options.

A. Dividends from a foreign corporation are fully taxable as regular income in Canada and do not benefit from the dividend tax credit.
B. Coupon payments from bonds are considered interest income, which is fully taxable at the investor's marginal tax rate, offering no tax preference.
D. Eligible dividends are tax-efficient due to the dividend tax credit, but for a top-bracket earner, the 50% inclusion rate on capital gains results in a lower effective tax rate.
