Reminder:
If you have held the stock for less than one year, you are only entitled to deduct from income your cost basis or the fair market value of that stock, whichever is lower. The deduction is limited to 50% of your adjusted gross income, with a five-year carry-forward. Please confirm with your tax accountant.
To maximize your tax benefit, it is best you have held your stocks for over 1 year and a day.
