While researching various financial strategies, you may have come across the Smith Manoeuvre—or Smith Maneuver, if you prefer the American spelling. Originally popularized by financial advisor Fraser Smith, the Manoeuvre has become a well-known method of lowering tax costs for Canadians; Mr. Smith even wrote a book on it!
But how does it work? To understand the Smith Manoeuvre, we first need to understand how mortgages in Canada are different from those in the U.S.
A mortgage is a loan taken out to help pay for a house, condo, or other residential property. For most people looking to buy a home, paying the full amount upfront is not feasible. Instead, they will pay what they can—this original amount is the down payment—and then take out a mortgage to help pay off the rest at a gradual pace. The loan is secured on the property, meaning that if the legal agreement is broken, your mortgage lender has the right to take your property.
In paying off a mortgage, you must make principal and interest payments. Mortgage principal refers to the outstanding balance of your mortgage. In other words, it is whatever is left of the original loan you took out. Interest is the additional amount owed, which accumulates on top of your original loan at a set rate. Canada and the U.S. treat mortgage interest differently; in the U.S., you can write off payments made towards mortgage interest on your tax returns, provided that it is your primary residence, while here in Canada, you cannot.
This is where the Smith Manoeuvre comes in.
To use this strategy, you first must have a readvanceable mortgage. These mortgages have lines of credit attached to them, which increase with each payment made towards the principal (original loan). Each mortgage payment pays partly on the principal and partly towards interest. So, if your monthly mortgage payment is $4,000, you might add $2,000 to the available credit in your line of credit with each payment.
Here’s where it gets interesting—you can invest money from this line of credit and deduct the interest on it on your tax return, provided you are investing it in an investment that could pay income. Essentially any stock market investment is usually fine, since they could pay a dividend (even if it doesn’t now). You can also pay the interest on your tax-deductible credit line from the credit line, so it does not affect your cash flow. This is called “capitalizing” the interest. In other words, you have now made a portion of your mortgage tax-deductible by creating a tax-deductible credit line from the money you borrowed to invest.
By doing this consistently and carefully, you can begin to build up your investments and create a “nest egg” to keep yourself financially secure. Because of its slow-building nature, the Smith Manoeuvre is best considered as part of your retirement plan. It allows you to invest without affecting your lifestyle, and has the added benefit of being easy to implement—you can start saving for your retirement now, and not in 20 years.
This strategy has the potential for some serious returns, too. In fact, the typical net expected benefit of the Smith Manoeuvre over 25 years is the amount of your current mortgage. So, if you currently have a $500,000 mortgage, you could clear $500,000 net gain after 25 years.
As with any borrowing-to-invest strategy, the SM is inherently risky, and should only be considered if you have a high risk tolerance and a long time horizon. The risks decline over time, and you should be prepared to stay invested through short-term market crashes. Best advice is to commit to doing it for at least 20 years. The most effective strategy is to use it as long as you own a home, even through your retirement.
When it comes to the Smith Manoeuvre, I’ve helped hundreds of Canadian families implement it professionally and properly. Remember Fraser Smith’s book? I am recognized as an expert on page 82.
If you believe this manoeuvre might be suitable for you, consider discussing it further with your financial planner. It might just be the boost your retirement plan needs.
