ESPP Qualifying vs. Disqualifying Dispositions
An ESPP with a lookback provision and 15% discount is one of the best risk-free returns available to employees. The purchase price is typically the lower of the stock price at the offering start or end date, multiplied by (1 − discount%).
Disqualifying disposition occurs when you sell within 2 years of the offering date or within 1 year of the purchase date. The entire spread (FMV at purchase minus purchase price) is taxed as ordinary income. Any additional appreciation above FMV at purchase is a short-term capital gain.
Qualifying disposition requires holding shares for at least 2 years from the offering date AND at least 1 year from the purchase date. Tax treatment splits the gain: ordinary income is recognized on the lesser of (a) the actual gain or (b) the discount at offering. Everything above that threshold is taxed as long-term capital gains — typically at a much lower rate.
The strategy: If the stock has appreciated significantly, qualifying dispositions produce large LTCG savings. If the stock has declined, a disqualifying disposition may be better since you recognize less ordinary income. Always sell ESPP shares in a tax-advantaged sequence if you hold multiple purchase lots.
