The 15% discount from your ESPP purchases should be included in your Box 1 Wages amount and the taxes withheld are also reported on your W-2. You may see the amount of your ESPP discount noted in Box 14.
You may also want to ensure that the 1099-B reports the sale of ESPP stock using the correct basis. There should be supplemental information on the 1099-B and your employer should provide Form 3922 which will have the adjusted basis that you would want to report. To adjust the basis on your sale of ESPP stock:
- In the Federal > Income & Expenses > Investment Income section of your return, click Start/Revisit next to Stocks, Cryptocurrency, Mutual Funds, Bonds, Other (1099-B)
- Answer Yes and then select stocks. Import or enter your transactions manually.
- For the ESPP transactions, make sure to select Yes to Do these sales include any employee stock?
- Enter the transactions as they appear on the 1099-B with ESPP selected as the type of investment.
- If the basis reported on the 1099-B is not correct, you will be able to adjust it to match the supplemental information provided under Adjust your cost basis to ensure your best outcome after you enter the stock sale. If your ESPP discount was not reflected on your W-2, you can also enter it as Amount of compensation income for this sale as you are guided through the ESPP sale screens.
