The Moment
Your employer offers an Employee Stock Purchase Plan (ESPP). You can contribute up to 15% of your salary (max $25,000/year in purchases) to buy company stock at a 5-15% discount. The most common structure: a 15% discount on the lower of the stock price at the beginning or end of the offering period (a "lookback" provision).
The ESPP discount is one of the best risk-adjusted returns available to employees. But many people skip it because the mechanics seem complicated. They are not.
Why You Should Participate
The math on a 15% discount: You contribute $10,000 over a 6-month offering period. At the end, you buy stock worth $11,765 (because you paid 85% of the price). That is a $1,765 guaranteed gain — a 17.6% return in 6 months, annualized to 35%+.
With a lookback provision (discount applied to the lower of start or end price), the return can be even higher. If the stock rose 20% during the offering period and you get 15% off the start price, your effective discount is 32%.
The worst-case scenario: The stock declines 15% during the offering period. Your 15% discount means you break even. You have lost nothing. In virtually every scenario, the ESPP discount provides a positive or break-even outcome.
The optimal strategy: Buy and sell immediately. Contribute the maximum. When shares are purchased, sell them the same day or within a few days. Take the guaranteed 15%+ return and invest the proceeds in a diversified portfolio. This eliminates concentration risk while capturing the full discount.
This is not investing in your company. It is harvesting a guaranteed return and reinvesting it properly.

Tax Treatment
Immediate sale (disqualifying disposition): The discount amount ($1,765 in our example) is taxed as ordinary income on your W-2. Any additional gain or loss is a short-term capital gain/loss. Simple.
Holding over 1 year from purchase AND 2 years from offering start (qualifying disposition): Part of the gain is taxed as ordinary income (limited to the actual discount), and the rest is taxed at long-term capital gains rates. The tax savings can be meaningful on large gains — but holding introduces concentration risk.
For most employees: The tax savings of a qualifying disposition do not justify holding a concentrated stock position for 1-2 years. Sell immediately, pay the slightly higher tax, and diversify.

Frequently Asked Questions
What if I cannot afford to contribute 15% of my salary?
Contribute whatever you can — even 1-3% captures the discount. If cash flow is tight, think of it as a forced savings plan with an instant 15% bonus. The shares convert to cash when you sell, so the impact on your take-home pay is temporary.
Is this the same as RSUs?
No. RSUs are granted to you for free and vest over time. ESPP requires you to contribute your own money, but you buy stock at a discount. RSUs are compensation; ESPP is a purchase opportunity with a guaranteed discount.
