How ESPP enrollment and decisions typically work
How does ESPP enrollment usually happen?
Most ESPPs run on fixed enrollment windows tied to offering periods, often opening 30 to 60 days before a new period begins. Employees elect a percentage of salary to defer through payroll, and that amount accumulates over the offering period before being used to purchase shares at the discounted price.
What's the typical decision after shares are purchased?
Two paths are common. Selling shares shortly after purchase locks in the built-in discount with minimal exposure to the stock. Holding shares for the qualifying period (one year after purchase and two years after the offering start) can convert some of the gain to long-term capital gains, though it also increases exposure to a single stock.
What's the trade-off between the two approaches?
Selling immediately captures a known return with low risk. Holding for the qualifying period offers potentially favorable tax treatment but introduces price risk on a stock the employee is already exposed to through their paycheck. The right approach depends on existing concentration and overall financial goals.

Concentration risk for employees holding company stock
What "concentration" means in this context
Concentration risk describes the situation where a meaningful portion of someone's net worth is tied to a single company's stock. For employees with equity compensation, this can build up over time without any deliberate decision, as vesting events deposit shares into the account and prior grants continue to accumulate.
Why the dynamic is different for employees
An employee with a large employer stock position has two exposures to the same company. Salary, bonus, future equity grants, and job security all depend on the company performing well. The stock position adds a second exposure to the same risk factor. A difficult period for the company can affect both at the same time, which is a different risk profile than holding the same stock without the employment connection.
What employees commonly weigh in this decision
The decision about how much company stock to hold is highly individual. Common factors include the total size of the position relative to other assets, the share of income that already comes from the employer, and the individual's view on the company independent of their job. There is no general answer that applies across situations.
Taxes on RSUs and ESPP shares: what to expect
Why withholding often falls short for high earners
The default federal withholding on supplemental income, including RSU vests and ESPP purchases, is 22 percent. For employees in the 32, 35, or 37 percent federal bracket, this rate is below the actual marginal rate, which creates a shortfall that accumulates across the year. The gap shows up as a balance due at filing time, and it often grows larger in years with multiple vests or strong stock appreciation.
What the tax forms look like
RSU vest income appears on the W-2 in box 1, included with regular wages. ESPP purchases generate a Form 3922 from the employer for each year of purchases, which contains the offering-date and purchase-date prices needed to calculate tax correctly when the shares are eventually sold. Sales of either type of share generate a Form 1099-B from the broker holding the shares.
A common ESPP reporting issue
The broker's Form 1099-B typically reports cost basis as the discounted purchase price, not the fair market value at purchase. The discount portion is already taxed as ordinary income through the W-2. Carrying the broker-reported basis straight onto Form 8949 without adjustment results in paying capital gains tax a second time on the same income. The adjustment is mechanical, but it requires knowing to look for it.
