Report proceeds from the sale or exchange of securities, commodities, and barter exchange transactions.
The IRS is retiring FIRE. It accepts information returns until 3 p.m. ET on 19 November 2026, and from 1 January 2027 IRIS is the only electronic channel - including for prior-year returns and corrections. New Transmitter Control Codes are no longer issued through FIRE, so a TCC application now has to go through IRIS.
IRS noticeForm 1099-B is issued by brokers and barter exchanges to report the sale of stocks, bonds, commodities, futures, and other securities. It reports gross proceeds, cost basis (if known), and whether the gain or loss is short-term or long-term. This information is used by taxpayers to complete Schedule D and Form 8949.

Yes. Unlike most 1099 forms, there is no minimum threshold for 1099-B. Every reportable sale or exchange must be documented.
If a wash sale occurred (selling a security at a loss and repurchasing within 30 days), the broker adjusts the cost basis and reports the wash sale adjustment in Box 1g.
