Frequently asked questions

What's a lookback?
Many ESPPs let you buy at a discount off the lower of the price at the offering start or the purchase date — a 'lookback' that boosts your gain when the stock rose.
How is ESPP taxed?
The discount is usually ordinary income; further gains are capital gains, and a 'qualifying disposition' (longer holding) gets better treatment. The full planner breaks this down.
