ESPP vs RSU for Canadian Employees: Tax Comparison

Many Canadian employees at publicly listed companies receive both an Employee Stock Purchase Plan (ESPP) and Restricted Stock Units (RSUs) as part of their total compensation. Both are governed by ITA section 7, but they are taxed differently, triggered at different points, and serve different financial purposes. Choosing how to participate in each — and how long to hold shares after acquisition — depends on understanding the distinct tax treatment that applies to each plan type.

ESPP: Discount Taxed at Purchase

In a typical ESPP, employees contribute a percentage of their salary over a six-month or twelve-month offering period. At the end of the period, the plan purchases shares on your behalf, usually at a 10-15% discount to the market price. Many plans also include a lookback provision: the discount is applied to the lower of the share price at the start or end of the offering period.

Under ITA section 7, the discount element is a section 7 benefit and is included in your employment income at the time of purchase. If you buy shares worth $100 at a 15% discount ($85), the $15 discount is Box 38 employment income in the year of purchase.

No section 110(1)(d) deduction is available for ESPP discounts. The discounted price is, by definition, below the FMV at the time of acquisition — which means the condition that the option price be no less than FMV at grant cannot be satisfied.

The ACB of shares acquired through an ESPP equals the FMV at purchase (i.e., $100 in the example above, not $85). The employment income was $15; any subsequent appreciation is a capital gain calculated from the $100 ACB.

RSU: Full Vest Value Taxed as Employment Income

RSUs deliver shares outright at vest with no employee contribution. The full FMV of vested shares is employment income at vest under section 7, with no deduction and no contribution required. See How RSUs Are Taxed in Canada for full mechanics.

Side-by-Side Comparison

Taxable event	Share purchase date	Vest date
Amount taxed as employment income	Discount only (e.g. 15% of FMV)	Full FMV at vest
Section 110(1)(d) 50% deduction	Not available	Not available
Employee cash contribution	Yes (payroll deduction)	No
Lookback feature	Available in many plans	Not applicable
ACB of acquired shares	FMV at purchase date	FMV at vest date
Capital gain on subsequent sale	Appreciation above FMV purchase price	Appreciation above FMV vest price

When ESPP Is More Tax-Efficient

The ESPP becomes particularly efficient when two conditions combine: the lookback provision is triggered (i.e., the share price has risen over the offering period, so the discount is applied to the lower start-of-period price) and you intend to hold the shares for appreciation.

In a rising-stock scenario with a 15% discount and a 25% stock appreciation over the offering period, the ESPP delivers approximately 40% immediate gain on contributed funds relative to your entry price. The employment income triggered at purchase is only the discount portion — a relatively small amount compared to the total value created.

ESPP participation can also be preferable for employees in lower marginal tax brackets (under ~40% combined federal + provincial), where the employment income cost on the discount is relatively modest and the subsequent capital gain benefit is more pronounced.

When RSU Is Preferable

RSUs have a key advantage: no cash outlay required. You receive shares without reducing your paycheque. For employees who cannot afford to direct 5-10% of salary to ESPP contributions without affecting cash flow, RSUs provide equity upside with no liquidity cost.

RSUs are also simpler to model. The taxable event is straightforward — vest FMV equals income equals ACB. There is no lookback calculation, no contribution timing decision, and no offering-period volatility to manage.

For employees who believe strongly in the company’s long-term trajectory and want maximum share exposure, RSUs ensure they hold shares regardless of market conditions at any particular purchase date. ESPP lookback value can disappear if the stock falls during the offering period — the discount shrinks to the current price and the employment income can exceed the immediate gain if the stock drops further after purchase.

Holding Shares and Capital Gains

Once you hold shares from either plan, the subsequent sale is treated the same way: capital gain or loss based on the difference between sale proceeds and ACB. The 50% capital gains inclusion rate applies to any net gain, and those gains are taxed at your marginal rate on the included amount.

One practical consideration: shares acquired through ESPP and RSU plans that are held in a non-registered account require careful ACB tracking, especially if you acquire shares from both plans in the same company. The CRA requires a weighted average ACB across all lots of the same security.
