Employee Stock Purchase Plans Explainer
An employee stock purchase plan, or ESPP, allows eligible employees to buy employer stock, commonly through payroll deductions collected during an offering period. Shares are purchased on scheduled dates under the plan’s price formula and administrative rules.
Some plans provide a discount and a lookback that bases the purchase price on the lower of values measured at the beginning and end of a period. Tax-qualified plans under Internal Revenue Code Section 423 must satisfy participation, term, price, and annual purchase-limit requirements.
Tax treatment depends on whether the plan qualifies and how long shares are held after the offering and purchase dates. Employers report specified transfers on Form 3922, and the employee needs accurate purchase price, fair market value, discount, and sale records to calculate basis and income.
A favorable discount can still be overwhelmed by a falling stock price, taxes, or concentration in the same company that provides the employee’s salary. Participants should understand blackout policies, contribution changes, refunds, sale timing, fees, and a diversification plan before treating the benefit as risk-free compensation.
Contributions accumulate until scheduled purchase dates.
Eligibility and withdrawal rules come from the plan.
The formula may use prices from different dates within an offering period.
Limits and tax rules constrain qualified plans.
Salary and portfolio value may depend on the same company.
A discount does not eliminate market or tax risk.
