You should have received a 1099-B from the brokerage firm that handled the stock trades or you should have a 1099-B available on your e*trade account. The transactions listed on your 1099-B need to be reported on your return. Whether or not you have to pay tax is determined by whether or not you have a gain or a loss.
The information you need to report is:
- Date of Acquisition
- Date of Sale
- Proceeds from Sale
- Cost Basis (what you paid for the original purchase)
- Whether it was Short -Term or Long-Term (Short-term means you owned it for 1 year or less; Long-term means you held it for more than 1 year).
All of this information should be reported on the 1099-B.
