How ESPP discounts are taxed
Canadian ESPPs operate under ITA s.7 (the same provision that governs employee stock options). The difference between the FMV of the shares on the purchase date and the discounted price you actually paid is a taxable employment benefit, reportable on your T4. Unlike stock options, there is generally no s.110(1)(d) 50% deduction — the discount benefit is fully taxable as employment income.
The lookback feature
Many U.S.-style ESPPs include a 'lookback' feature: the discount is applied to the lower of the FMV at the start of the offering period or the FMV at the purchase date. When the share price has appreciated during the offering period, this substantially increases the discount benefit — and the tax owing.
What happens when you sell
Your adjusted cost base for the purchased shares is the FMV on the purchase date (= what you paid plus the discount benefit). If you sell at a higher price later, you have a 50% taxable capital gain on the appreciation. If you sell at a lower price, you have an allowable capital loss usable only against capital gains.
Frequently asked questions
How is an ESPP discount taxed in Canada?
Under ITA s.7, the difference between the fair market value of the shares on the purchase date and the discounted purchase price is a taxable employment benefit. The benefit is taxed in the year of purchase, regardless of whether you sell the shares. Your adjusted cost base for capital-gains purposes is the FMV on the purchase date (i.e., what you got plus the discount benefit).
What is the lookback feature and how does it affect tax?
A lookback ESPP applies the discount to the lower of the FMV at the start of the offering period or the FMV at the purchase date. This typically produces a bigger discount benefit (taxed as employment income at purchase) when the share price has appreciated during the offering period.
Should I sell my ESPP shares immediately or hold?
Selling immediately locks in the discount benefit yield with no further market risk; the capital-gain component is zero (you sell at ACB). Holding exposes you to capital gain or loss on appreciation, with 50% inclusion. The tax math doesn't strongly favour either approach — the decision is mostly about diversification and concentration risk.
