How It Works
Buying shares through an Employee Stock Purchase Plan (ESPP) comes with tax rules and potential gains that are easy to misjudge, and this tool lays them out so you can see where you stand. In 2026, ESPP purchases stay capped at $25,000 per calendar year measured by fair market value, so planning carefully is what lets you wring the most out of the benefit.
Two figures drive the outcome: the purchase discount, usually 5-15% below market price, and the tax treatment that hinges on how long you hold. The calculator separates qualifying dispositions, where shares are held at least two years from grant and one year from purchase, from disqualifying dispositions, and that distinction decides whether your gain is taxed as ordinary income or as capital gains.
The discount itself is taxed as ordinary income no matter how long you hold the shares. Many plans also include a lookback provision that lets you buy at 85% of the lower of the stock price at enrollment or on the purchase date, and overlooking it is a frequent oversight. Because the fine print differs from plan to plan, it is worth confirming your own plan's terms, since tax outcomes can swing widely.
ESPP Purchase: $5,000 contribution with 15% discount on $50 stock
- 1 Inputs: stock price $50 at both the offering start and the purchase date, annual salary $50,000 with a 10% contribution ($5,000), and a 15% discount. The purchase price is $50 × 85% = $42.50 per share.
- 2 Shares purchased: $5,000 ÷ $42.50 = 117.65, rounded down to 117 shares, costing 117 × $42.50 = $4,972.50.
- 3 Discount: ($50 − $42.50) × 117 = $877.50. It becomes ordinary income in the year you sell the shares, not when you buy them.
- 4 If sold immediately at $50 per share (a disqualifying disposition), proceeds are $5,850, the full $877.50 is ordinary income reported as wages, and there is no capital gain. Held for the qualifying period and sold at $50, the ordinary income is the smaller of the offering-date discount ($7.50 × 117 = $877.50) and the actual gain, so it is also $877.50 here; any rise above $50 would be long-term capital gain.
