How to Report Stock Loss

• 1). Obtain Schedule D for Form 1040. This form can be downloaded from the Internal Revenue Service website. Tax software should ask you if you have any capital gains or losses to report.
  
  
• 2). Determine whether your stock was a long-term or short-term holding. Stocks held less than one year are classified as short-term holdings.
  
  
• 3). Fill out the information about your particular stock in part I of Schedule D if the stock was held short term and part II if the stock was held long term. You will need to know the date you purchased the stock, the amount you paid for the stock, the date you sold the stock and the amount you received when the stock was sold.
  
  
• 4). Follow the instructions on the Schedule D form to finish computing the total amount of your loss and the amount of the loss you can claim in the current year. There is a limit to the amount of capital loss that can be claimed in a given tax year. You may carry over any unclaimed loss for use in future tax years.
  
  
• 5). Record the amount of loss calculated on line 22 of Schedule D and on line 13 (capital gains and losses section) of Form 1040.
  
  
• 6). When adding the first several lines on Form 1040 to arrive at your total income, deduct the amount of the loss you reported on line 13 as a capital loss.
