Stock options and employee share purchase plans (ESPPs) have special tax treatment in Canada. When you exercise an option to buy company stock at a discounted price, only 50% of the benefit is included in your taxable income, and this amount is taxed as employment income (not as a capital gain). If you later sell the shares for a profit above your exercise price, that additional profit becomes a capital gain and is subject to the inclusion rate that applies in the tax year of sale. Understanding how stock options work tax-wise is crucial for Canadian employees, especially those in tech, finance, or other industries that offer equity compensation. The rules differ based on the type of option, the exercise price, and when you sell. Stock options trigger taxation at two different moments: 1. At exercise: When you buy shares using your option, the difference between the fair market value and your exercise price is a taxable employment benefit. This is added to your employment income, and only 50% of this benefit qualifies for the deduction (meaning 50% of the benefit is included in income). 2.
Yes. When you exercise, the difference between the fair market value and your exercise price is a taxable employment benefit added to your income in that tax year. You pay tax immediately, even if you haven't sold the shares yet.
The benefit at exercise is taxed as employment income. However, 50% of the benefit may be deductible if the plan meets CRA criteria for prescribed shares. Any gain or loss when you later sell is then treated as a capital gain or loss.
If the fair market value is below your exercise price, there is no taxable benefit. You only pay tax if the stock is worth more than the exercise price at the time you exercise.
Yes. If you sell shares below your exercise price, you have a capital loss. You can use this loss to offset other capital gains in the same year or carry it back three years or forward indefinitely.
Many employers withhold tax on the employment benefit when you exercise. This is a prepayment of your tax, not the final bill. You may owe more or receive a refund when you file your return, depending on your total income and other deductions.
