Marginal Tax Rate and the Smith Maneuver

📅 July 22, 2026 Personal Finance Canada

Marginal tax rate and the Smith Maneuver

The marginal tax rate is a fundamental concept in personal finance that represents the tax rate applied to the last dollar earned. Understanding this concept is essential to making informed wealth management decisions, especially when it comes to the Smith Maneuver, a popular financial strategy in Canada.

What is the marginal tax rate?

The marginal tax rate varies depending on annual income and province of residence. In Canada, marginal tax rates are progressive, meaning the tax rate increases as income increases. For example, a person earning $100,000 per year in Quebec will pay a marginal tax rate of 24%, while someone earning $200,000 per year will pay a marginal tax rate of 27.75%.

What is the Smith Maneuver?

The Smith Maneuver is a financial strategy that involves borrowing money for investment purposes, usually to buy stocks or mutual funds. The idea is to borrow money at an interest rate lower than the expected rate of return on the investment, which can generate additional income. However, it is important to consider the marginal tax rate when implementing this strategy.

Who benefits the most from the Smith Maneuver?

People with high incomes and high marginal tax rates benefit the most from the Smith Maneuver. Indeed, if the interest rate of the loan is lower than the marginal tax rate, the loan may be deductible, which reduces the tax payable. For example, if a person earns $500,000 per year and pays a marginal tax rate of 33.33% in Quebec, they can borrow $200,000 at 3% to invest in stocks. If the shares generate a return of 8%, the difference between the rate of return and the interest rate (5%) may be considered a taxable gain, but deducting the interest paid on the loan reduces the tax payable.

To find out if the Smith Maneuver is appropriate for your financial situation, it is recommended to consult a financial expert or visit websites such as RSSUS.com for personalized advice and financial planning tools.

In conclusion, the Smith Maneuver can be an effective financial strategy for people with high income and a high marginal tax rate, but it is essential to consider the risks and costs associated with borrowing and investing. It is recommended that you consult a financial expert to determine whether the Smith Maneuver is appropriate for your financial situation.
