    Overview

    Form 1099-B is used by brokers and barter exchanges to report sales of stocks, bonds, commodities, futures contracts, and other securities. The form reports gross proceeds from the sale and, for covered securities, the cost basis and gain/loss information.

    Brokers must report whether securities are covered (basis reporting required) or noncovered. For covered securities acquired after specific dates, brokers must report the cost basis, allowing the IRS to verify capital gains reporting.

    Important Filing Notes

    Covered vs. Noncovered

    Covered securities have cost basis reported to IRS. Stocks acquired after 2011, mutual funds after 2012, and bonds/options after 2014 are typically covered.

    Wash Sale Rules

    Box 1e shows losses disallowed under wash sale rules (buying substantially identical security within 30 days before or after sale). Disallowed loss is added to basis of replacement security.

    Early Deadline for Customers

    Brokers must furnish Form 1099-B to customers by February 15, earlier than most other 1099 forms, to give taxpayers time to prepare returns.
