Employee Stock Purchase Plans
Getting the most out of an ESPP without adding risk
An employee stock purchase plan is the closest thing to free money most tech employees are offered, and a surprising number of them leave it on the table. A 15% discount with a lookback is a guaranteed return on the day you buy; what you do after that is where the planning is.
We help clients decide how much to contribute, whether to sell at purchase or hold for better tax treatment, and how to keep the ESPP from quietly compounding a concentration problem alongside their RSUs.
What the discount is actually worth
Most plans let you buy at 15% below the lower of the price at the start of the offering period or the price on the purchase date. If the stock rose during the period, the lookback means you buy at 15% off the older, lower price, and the built-in gain on purchase day can be 30% or more. Because contributions are deducted over six months, the cash is only tied up for about three months on average, so the annualized return is far higher than the headline discount suggests. Our ESPP calculator works it out for your plan’s numbers.
The catch is that the discount is taxable compensation, always. The only question is how much of your profit is taxed as ordinary income and how much as long-term capital gain, and that depends on when you sell.
Sell now, or hold for qualifying treatment?
Sell right away
The whole spread between the purchase-date price and what you paid is ordinary income on your W-2. You lock in the discount, take no stock risk, and can redeploy the cash into a diversified portfolio the same week.
Hold two years from the offering date
Ordinary income is capped at the discount measured on the offering date; the rest of the gain is long-term capital gain. The tax saving is real, but you hold a concentrated position for a year or more to earn it.
Concentration usually decides it
If the stock is already a large share of your net worth, the tax saving from holding rarely justifies the added risk; a 5% to 8% drop in the share price wipes it out. If your exposure is modest, holding can make sense.
The 1099-B basis trap
Brokers report the discounted purchase price as your basis, not the price after the W-2 income is added. Without an adjustment on Form 8949, the discount is taxed twice.

How ESPP fits the rest of the plan
Contribute the maximum if cash flow allows. The IRS limit is $25,000 of stock per year at the undiscounted price, and many plans cap contributions at 10% or 15% of pay. The discount is large enough that funding it ahead of most other savings goals, other than capturing a 401(k) match, is usually right.
Decide the sell rule in advance. A standing instruction to sell on the purchase date, or to hold a fixed fraction, removes the temptation to time the stock and keeps the position inside your concentration ceiling.
Count it with your RSUs. ESPP shares, vested RSUs and any options are all the same company. We track the combined position against one limit and plan sales across all three, including the RSU withholding gap the ESPP income can widen.
