How this works

  • Step 1 — Grant: Your employer grants you options to buy shares at a set price (the exercise price). No tax at this point.
  • Step 2 — Exercise: You exercise the options and buy shares at the exercise price. If the shares are worth more than what you paid, you've received a taxable employment benefit equal to the spread.
  • Step 3 — Division C deduction: If the exercise price was at least the share's fair market value when the option was granted (the option was not in-the-money at grant), you can deduct 50% of the benefit from income, effectively halving the inclusion rate to match capital gains treatment. Note that the grant-date FMV never changes the taxable benefit itself — it only determines whether this deduction is available.
  • Step 4 — Sale: When you eventually sell, your ACB (adjusted cost base) is effectively the FMV at the time you exercised — not what you paid. The taxable benefit you received is added to your purchase price. Any gain above that ACB is a capital gain, 50% of which is included in income.
