How is my Employee Stock Purchase Plan (ESPP) taxed when I sell the shares?

ESPP tax treatment is one of the most misunderstood areas of employee compensation taxes. The key variable is how long you hold the shares after purchase — which determines whether your sale is a "qualifying" or "disqualifying" disposition.

Qualifying Disposition (better tax treatment):

To qualify, you must hold the shares for:

• At least 2 years from the offering/grant date, AND
• At least 1 year from the purchase date

If both tests are met, the discount you received at purchase is taxed as ordinary income, but only up to a capped amount based on the original offering price — not the market price at purchase. Any additional gain above that is taxed at the more favorable long-term capital gains rate (0%, 15%, or 20%).

Disqualifying Disposition (less favorable):

If you sell before meeting either holding period, you have a disqualifying disposition. The entire discount you received (the difference between what you paid and the fair market value on the purchase date) is treated as ordinary income and shows up on your W-2. Any remaining gain (if the stock appreciated further) is a short-term or long-term capital gain depending on how long you held after the purchase date.

Common mistake: Many employees don't realize that even if their employer does not include the ESPP income on their W-2, they still owe tax on it. And a separate mistake: using the wrong cost basis. Your brokerage's 1099-B may show a lower cost basis than your adjusted basis (which includes the compensation income already taxed), leading people to double-pay tax. Always check that the cost basis on Form 8949 reflects your adjusted basis.

Reporting: Report the sale on Schedule D and Form 8949. If you received a 1099-B with an incorrect basis, check Box B or Box E and enter the corrected basis in Column (e).
