Employee Stock Purchase Plans — The McLean Group Equity Compensation Advisory
How ESPPs work, their tax implications, strategic benefits—and how experienced advisors help companies design and manage them effectively.
An Employee Stock Purchase Plan (ESPP) is a company-sponsored benefit that allows employees to purchase shares of their employer's stock at a discount, typically through payroll deductions accumulated during an offering period.
A lookback provision allowing purchase at the lower of the price at the start or end of the offering period
These design elements often create an immediate economic benefit for participating employees.
A typical ESPP moves through three structured phases:
Employees elect to participate and designate a percentage of their salary to be deducted from each paycheck over the offering period.
Payroll deductions accumulate over the offering period. In plans with a lookback feature, the purchase price is determined by the lower of the stock price at the beginning of the offering period or the stock price on the purchase date.
At the close of the offering period, accumulated funds are used to buy company stock at the discounted price. The example below illustrates how meaningful this benefit can be:
Illustrative Example — With Lookback Provision
With a lookback, the purchase price is 85% × $50 = $42.50. Employees immediately receive shares worth $70—an embedded gain of $27.50 per share at the moment of purchase.
In the United States, ESPPs are frequently structured under Internal Revenue Code Section 423, which provides favorable tax treatment if specific statutory requirements are met.
Favorable tax treatment on qualifying dispositions
Tax outcomes for employees depend on how long they hold shares after purchase. There are two key scenarios:
Disposition Type Holding Requirement Tax on the Discount Tax on Additional Gains
Qualifying ≥ 1 year post-purchase & ≥ 2 years post-offering date Ordinary income Long-term capital gains
Disqualifying Sold before meeting holding requirements Ordinary income Short-term capital gains
These tax rules have a direct bearing on employee decisions about whether to hold or sell ESPP shares following the purchase date.
Companies implement ESPPs for several strategic purposes that extend beyond simple compensation:
Broad-Based Ownership — ESPPs allow participation across the entire organization, not just the executive level, creating wider stakeholder alignment.
Employee Engagement — Ownership strengthens the connection between individual employees and shareholder interests.
Competitive Compensation — Equity participation is a key tool for attracting talent, particularly in technology, life sciences, and growth-oriented sectors.
Retention and Culture — Employees who own stock develop a stronger connection to company performance and long-term success.

Employee Stock Purchase Plans remain one of the most accessible and effective mechanisms for expanding employee ownership and aligning workforce incentives with corporate performance. When thoughtfully designed, ESPPs can generate meaningful financial benefits for employees while strengthening engagement and retention.
Many companies integrate ESPPs with stock options, restricted stock units (RSUs), and performance-based equity awards. Because ESPPs intersect with valuation, accounting, tax, and capital structure considerations, companies often benefit significantly from working with experienced financial advisors throughout the process.
