1099 Consolidated Statement
Brokers do not always issue standard Forms 1099-B. Instead, they may issue their own statement entitled 1099 Consolidated Statement or Substitute 1099, which shows stock sales and other types of distributions, such as dividends and interest.
If the securities sold were noncovered securities, Form 1099-B would not report the date the stock was originally purchased, the original purchase price, or any adjustments to the basis. Some brokers report this information on a tax reporting supplement, if not, the taxpayer must provide you with the information.
