What are Employee Stock Purchase Plans (ESPPs)?
A Guide for Young Professionals
Employee Stock Purchase Plans (ESPPs) are a fantastic benefit many companies offer, allowing employees to purchase company stock, often at a discounted price. This provides a great opportunity to own a piece of the company you work for and potentially build wealth.
ESPPs can seem a bit complex at first, with terms like “offering period,” “purchase period,” and “look-back period.” This guide will break down all the key aspects, including how ESPPs work, their tax implications, and strategies for making the most of them.

How ESPPs Work
Purchase Discount
One of the most attractive features of an ESPP is the purchase discount. Companies typically offer a discount of up to 15% on the market price of their stock.
Offering Period
The offering period is the timeframe during which you can enroll in the ESPP and elect to purchase shares.
Purchase Period
The purchase period is when the actual purchase of the stock takes place. This usually occurs at the end of the offering period.
Look-Back Period (If Applicable)
Some ESPPs have a “look-back period.” This means the purchase price is based on the lower of the stock price at the beginning or the end of the offering period. This can be a significant advantage if the stock price rises during the offering period.
Let’s say the offering period is three months. If the stock price is $50 at the beginning and $60 at the end, the look-back provision would allow you to purchase the stock at the discounted price based on the $50 price.
Example Purchase With Look-Back
π
April 1, 2023 β Offering Period Begins
πΉ Stock price at start: $45
πΉ Employees enroll in the ESPP program and commit to payroll deductions.
π
September 30, 2023 β Offering Period Ends
πΉ Final contributions are accumulated.
π
October 1, 2023 β Purchase Date
πΉ Stock price on purchase date: $55
πΉ Lookback Feature: Employees get the lower of the start price ($45) or purchase date price ($55).
Discount Calculation:
Lower price: $45
15% discount: $45 Γ 0.85 = $38.25 per share
Shares purchased at: $38.25 per share
β
Outcome: Employees buy shares at $38.25, a 30.5% discount from the market price of $55.
Tax Implications of ESPPs
Qualified vs. Disqualifying Dispositions
The tax treatment of ESPP shares depends on whether you have a “qualified” or “disqualifying” disposition. This is crucial to understand.
A qualified disposition occurs when you sell your ESPP shares after meeting specific holding period requirements (generally two years from the offering date and one year from the purchase date). This results in the most favorable tax treatment.
A disqualifying disposition happens if you sell your shares before meeting those holding period requirements. This results in a higher tax burden.
Tax Implications (Qualified Disposition)
Tax Treatment
Ordinary Income: The discount at offering price is taxed as ordinary income. Ordinary Income = Lookback Price Γ Discount Rate
Long-Term Capital Gains (LTCG): Any additional gain (or loss) from the sale price above the purchase price + ordinary income is taxed at LTCG rates.
Example
Lookback Price (Start of Offering Period): $45
Purchase Date Price: $55
Actual Purchase Price (After 15% Discount on $45): $38.25
Sale Price: $70
Taxes:
Ordinary Income: $45 Γ 15% = $6.75 per share
Long-Term Capital Gains: $70 – $38.25 – $6.75 = $25 per share (LTCG rate)
Better tax treatment β the majority of gains are taxed at the lower long-term capital gains rate.
Tax Implications (Disqualifying Disposition)
Tax Treatment
Ordinary Income: The difference between the purchase price and the actual market price on purchase date is taxed as ordinary income.
Ordinary Income = Market Price on Purchase Date β Actual Purchase Price
Capital Gain/Loss: Any additional gain (or loss) is taxed at short-term or long-term capital gains rates, depending on the holding period after purchase.
Example
Lookback Price: $45
Purchase Date Price: $55
Actual Purchase Price (15% Discount on $45): $38.25
Sale Price: $70
Taxes:
Ordinary Income: $55 – $38.25 = $16.75 per share (taxed at ordinary income rates)
Capital Gain (LTCG/STCG based on holding period after purchase): $70 – $55 = $15 per shareIf held β€ 1 year: Short-term capital gains (ordinary tax rate)
If held > 1 year: Long-term capital gains
