I am in the 1099-B section, they are requesting a date column 1B - Date Acquired. On my statement it states N/A. How do I add that for a date?

The issuer of the IRS form 1099-B either does not have the information or is not required to report the information.  Even though there is no date of acquisition, does it report either long-term or short-term?

Are you able to find the date acquired by reviewing your internal records and sales tickets?

The dates of purchase and sale are used to determine long-term or short-term investments.  

• Short-term gains or losses come from the sale of investments owned one year or less.
• Long-term gains or lossses come from the sale of investments held more than one year.

As a rule, tax rates are more attractive for long-term investments.
