Form 1099-B (Proceeds from Broker and Barter Exchange Transactions) is the form brokers, dealers, and barter networks use to tell the IRS exactly how much money moved when an asset changed hands. Think of it as the paper trail behind every stock sale, fund redemption, option closeout, or barter swap.<\/p>\n
Each return shows:<\/p>\n
If it was sold, swapped, or bartered, it generally shows up on Form 1099-B. For example, stocks, ETFs, mutual-fund shares, commodities, or services through a barter exchange are reported on this form.<\/p>\n
Note: Sales or exchanges of digital assets are reported on Form 1099-DA for transactions effected in 2025.<\/p>\n
Generally, broker-reported sales have no minimum dollar threshold, but specific exceptions apply for barter exchanges under \u00a7 6045. For example, brokers aren\u2019t required to file, but may file Form 1099-B<\/a> for sales of fractional shares under $20 or for certain barter-exchange transactions under $1.<\/p>\n A late filing can cost $60 to $340 per form and at least $680 for intentional disregard. But beyond money, late reports break trust. Investors depend on their 1099-B recipient copy to finish their income tax returns accurately, and the IRS matches it line by line with Schedule D and Form 8949.<\/p>\n If a broker or barter exchange handles the sale or exchange of assets for someone else, it generally files this form.<\/p>\n When a broker processes a sale or exchange and there are proceeds, they must file either Form 1099-B for securities or Form 1099-DA for digital assets unless an IRS exception applies. For brokered securities, there\u2019s no dollar minimum. The $0 threshold makes it one of the IRS\u2019s most thorough securities proceeds reports.<\/p>\n *Digital-asset brokers report sales\/exchanges on Form 1099-DA for calendar year 2025 transactions (statements furnished in 2026), with transition relief for certain reporting and backup-withholding obligations.<\/p>\n Mark the Form 1099-B due date for recipient copies, IRS copies, and extensions now to help you stay compliant.<\/p>\nWho Must File Form 1099-B and When a Transaction Triggers Reporting<\/h2>\n
