Form 1099-B is an IRS information return that brokers use to report proceeds from certain sales and other reportable securities transactions, and that barter exchanges use to report exchanges of property or services through a barter exchange. This guide on broker barter exchange reporting will walk you through 1099-B instructions (2026), the deadlines, and details on cost basis reporting.<\/p>\n
Form 1099-B is an IRS form that brokers use to report the proceeds a customer received from selling or trading investments. This includes shares, bonds, mutual funds, options, futures, commodities, and foreign currency contracts. It is also used for transactions carried out through organized barter exchanges.<\/p>\n
Key information reported includes:<\/p>\n
Digital asset sales effected in 2025 are generally reported on Form 1099-DA, not Form 1099-B.<\/p>\n
Accuracy in 1099-B filing is essential because the IRS compares the Form 1099-B amounts to what the recipient reports on their tax return (often on Form 8949\/Schedule D). Mismatches can trigger a CP2000 notice, which can result in additional tax, penalties, and interest.<\/p>\n
Late, missing, or inaccurate Form 1099-B filings can trigger penalties ranging from $60 to $340 per return, depending on how late the correct return is filed. If the failure to file correctly is considered to be due to intentional disregard, the penalty is at least $680 per return, and there\u2019s no maximum penalty for intentional disregard. Backup withholding remains 24% when required.<\/p>\n
A broker or a barter exchange must file Form 1099-B for each person who:<\/p>\n
Brokers<\/b><\/p>\n
Brokers can be clearing organizations, banks, online trading platforms, and other institutions that execute or process trades on behalf of clients. Brokers may provide a consolidated statement that includes Form 1099-B, but they must ensure each component remains clearly labeled.<\/p>\n
There\u2019s generally no minimum dollar threshold for most reportable broker transactions, but the Form 1099-B instructions list specific exceptions (for example, sales of fractional shares of stock if gross proceeds amount to less than $20).<\/p>\n
Barter Exchanges<\/b><\/p>\n
