What is Form 1099-B?

Form 1099-B is useful for reporting and calculating taxes that apply to capital gains. For instance, the form will disclose the proceeds of the sale and how much of those proceeds are capital gains, as well as whether those gains are long-term or short-term in nature (this affects the taxability of the gain). Brokerage firms must send the forms to taxpayers by January 31 of each year.
