What if I have worthless stock?
If you had stock that became worthless in 2012, treat the worthless stock (has no value) as being sold on the last day of the year for a sales price of zero. Enter the cost basis (amount you paid) of the stock and the date it was acquired. Enter December 31, 2012 for the date sold since worthless stock is considered to be disposed of on the last day of the year.
