About this tool

Enter the offering and purchase dates, the share price at the start and end of the period, your discount, how much you contributed and when and at what price you sell. The tool finds your purchase price, checks the holding periods and splits your gain into ordinary income and capital gain.

Purchase price

With a lookback, the price is the lower of the price at the offering date and at the purchase date, less the discount (up to 15%). Without a lookback it is the purchase-date price less the discount.

Qualifying or disqualifying

A sale is qualifying if you sell more than two years after the offering date and more than one year after the purchase date. Then the ordinary income is the smaller of your real gain and the offering-date price minus your purchase price; the rest is long-term capital gain.

Otherwise it is a disqualifying sale: the ordinary income is the purchase-date price minus what you paid, and the rest is a capital gain or loss that is short term if you held a year or less.

Not covered

Alternative minimum tax, state tax and the 3.8% net investment income tax are not included.

Worked example

Offering price $50, purchase-date price $70, 15% discount with lookback: you pay $42.50 and $10,000 buys 235 shares. Selling at $90 on 1 August 2026 is qualifying: $1,763 is ordinary income and $9,400 is long-term gain, for about $1,974 of tax at 32% and 15%. Selling at $90 before the holding periods end makes $6,463 ordinary income and $4,700 short-term gain.

Tips for best results

Check every box before you rely on a result, because one wrong digit changes the whole answer. Use the exact figures from your payslip, bill, certificate or contract, and keep a note of the date you calculated. Rates, thresholds and rules change from time to time, so for tax, fees and legal matters treat the output as an estimate and confirm with the official source named on this page. You can run as many scenarios as you like; nothing is saved or sent, and refreshing the page clears the boxes.
