Stock Option Taxation
Three regimes apply to employee stock options under ITA s. 7: non-CCPC under the $200k annual vesting cap (50% deduction at exercise), non-CCPC above the cap (full inclusion), and CCPC options (deferral to disposition, 50% deduction if held two years). Contractor equity falls outside s. 7 entirely.

1. The s. 7 framework
When an employee exercises a stock option granted by reason of employment, the spread between FMV at exercise and the exercise price is an employment benefit (ITA s. 7(1)(a)). The benefit is added to Box 14 of the T4 and to Box 38 as a memo. A subsequent sale gives rise to a separate capital gain or loss measured from FMV at exercise.
2. The 50% deduction — s. 110(1)(d)
Half the s. 7 benefit is deductible (the so-called "stock-option deduction") if:
- The exercise price was ≥ FMV at grant;
- The option was on prescribed shares (ordinary common); and
- The option was not non-qualified under the $200k cap (post-30 June 2021).
3. CCPC options — s. 7(1.1) deferral
For options on shares of a Canadian-Controlled Private Corporation the s. 7 benefit is deferred until the employee disposes of the shares, not when they exercise. A separate 50% deduction (s. 110(1)(d.1)) applies if the shares are held for at leasttwo years after exercise, regardless of whether the exercise price matched FMV at grant.
4. The $200,000 annual vesting cap (non-CCPC)
For options granted on or after 1 July 2021 by employers other than CCPCs and not "qualifying persons" (revenue ≤ $500m), the s. 110(1)(d) deduction is capped at$200,000 of underlying share FMV per vesting year (ITA s. 110(1.31)). Options above the cap are designated "non-qualified" and the employer takes a matching corporate deduction under s. 110(1)(e) — the only situation in Canadian tax where stock options generate a corporate deduction.
5. Three worked examples
A — Non-CCPC, under the cap.
Priya is granted 5,000 options at $20 (FMV at grant). Three years later FMV is $50; she exercises. Benefit = 5,000 × $30 = $150,000. Within the $200k cap, so 50% deduction applies → $75,000 net taxable.
B — Non-CCPC, above the cap.
Same facts but FMV at grant of vesting tranche is $250,000. The $50,000 excess is non-qualified: no 50% deduction on that slice. Net taxable = $100,000 (50% × $200k) + $50,000 = $150,000.
C — CCPC, two-year hold.
Mira exercises 10,000 CCPC options in 2025 at exercise price $1 (FMV $5). No tax in 2025 (s. 7(1.1)). In 2028 she sells at $30. Employment benefit = 10,000 × $4 = $40,000 (with 50% s. 110(1)(d.1) deduction since held > 2 years → net $20,000). Capital gain = 10,000 × $25 = $250,000 (50% taxable → $125,000).
6. Contractor & founder equity
Equity granted to a non-employee contractor is not in s. 7. CRA treats it as business income at FMV when received (T2125), without any 50% deduction. Founders who subscribe for shares at incorporation hold pure capital property — no s. 7 benefit, only a capital gain on eventual sale (LCGE may apply to QSBC shares).
7. AMT interaction
For 2024 onward only 50% of the stock-option deduction is allowed in the Alternative Minimum Tax base — meaning the full s. 7 benefit is effectively included. An employee exercising large NSO blocks can owe AMT even after applying the s. 110(1)(d) deduction for regular tax. Carry-forward is seven years.
8. TOSI on family-member options
Options granted to a spouse or adult child who is not actively engaged in the business are caught by Tax on Split Income (s. 120.4), taxing the s. 7 benefit at the top marginal rate with no 50% deduction. The "excluded shares" carve-out is rarely available on option exercises.
