How the calculation works
When you exercise an employee stock option, the difference between the fair market value of the shares on the exercise date and the option's strike price is a taxable employment benefit (ITA s.7(1)). For most options granted by public companies, you can claim a 50% deduction on this benefit under s.110(1)(d), provided the strike price was at least the FMV at grant and the shares meet the Regulation 6204 conditions.
The $200,000 vesting cap (2021 Budget): For options granted by non-CCPC public companies after 2021-06-30, the 50% deduction is capped at $200,000 of options vesting in any one calendar year, measured at FMV on the grant date. Options vesting above the cap produce option benefits that are fully taxable as employment income with no 110(1)(d) relief.
CCPC vs Public-Company Options: Employees of a Canadian-Controlled Private Corporation defer the option benefit until disposition of the shares rather than recognizing it at exercise. The deferral, plus a potential 50% deduction at disposition if the shares are held two years, makes CCPC equity materially more tax-efficient than non-CCPC public company options.
Frequently asked questions
What is the section 110(1)(d) stock option deduction?
Section 110(1)(d) of the Income Tax Act lets eligible employees deduct 50% of the option benefit when an option is exercised. The option must be on prescribed shares and the strike price must be at least the FMV at grant.
What is the $200,000 vesting cap?
Since 2021-07-01, options granted by non-CCPC public companies have an annual $200,000 vesting cap on the 50% deduction. Vesting amount means the fair market value of shares underlying options that vest in a given calendar year.
How are CCPC stock options taxed differently?
Employees of a Canadian-Controlled Private Corporation defer the option benefit until disposition. They may also claim the 50% deduction at disposition if shares are held at least two years, making CCPC equity more tax-efficient.
Are there carve-outs for qualifying start-ups?
Yes. The $200,000 vesting cap does not apply to qualifying start-ups under section 110(1)(d.1). Certain small-business corporations may be exempt from the cap.
Does exercising an option count as a capital gain?
No. The option benefit is employment income, not a capital gain. Only the gain when you later sell the shares (or the value increase between exercise and sale) is a capital gain, eligible for the 50% capital gains inclusion.
