The unprecedented volatility in bond markets over the past two years has resulted in many bonds trading at discounts to their par values. These bonds can offer a tax-efficient approach to generating returns for investors over the coming years.
Bonds that are trading below their par value are referred to as “discount bonds,” and they can be very attractive to investors for two reasons:
- The yield to maturity, or return over the remaining lifetime of the bond, is higher than when it was first issued at par.
- The tax treatment of the return is more efficient because a portion of that bond’s return is now treated as capital gains and taxed at a much lower level than interest income.
Discount Bonds in Action
Let’s look at a hypothetical $100 bond with an initial return expectation of 4% and a 2-year term issued in January of 2023. A month later, due to a market adjustment (ex., a rate hike), the required return increases to 6%.
The increase in return to 6% is derived from now having the opportunity to buy the bond at $96.6 (instead of the original $100). Then investors can see that price move to $100 over the remaining 23 months of the bond.

This additional 2% in return is treated as a capital gain and not interest income for new holders of this hypothetical bond and is in addition to the coupon payments of 4% that investors will continue to receive.
Implications on the After-Tax Return
One way to understand the impact of this is by looking at the after-tax returns of a GIC relative to a discounted bond with the same term to maturity.
Buying bonds with similar maturities to a locked-in GIC can provide notably higher after-tax yields for investors who are in high tax margin brackets. This is simply because the return earned on GICs is taxed entirely as interest income, whereas a portion of the total return generated from discounted bonds is taxed at the lower capital gains tax rate.

Additionally, most fixed income mutual funds that purchase discount bonds can readily provide daily liquidity, unlike locked-in GICs, whose term typically can not be broken without incurring significant penalties.
