Form 1099-B reporting can involve a lot of transaction-level details, from proceeds and basis to holding-period information. 1099Online helps bring those details into one filing workflow, with tools for bulk import, TIN matching, eFiling, and recipient copy delivery.
Form 1099-B is the IRS information return for reporting proceeds from broker and barter exchange transactions. On the broker side, it reports the proceeds from sales and, in many cases, the cost basis and holding-period details that go with them. On the barter side, it reports property or services exchanged through a barter exchange. Recipients use this information to report the transaction on their tax return, generally on Form 8949 and Schedule D when applicable. If the proceeds, basis, or holding period is reported incorrectly, the recipient may also need to make adjustments when filing.
A broker or barter exchange has to file Form 1099-B for each person in any of these three situations:
Qualified Opportunity Funds (QOFs) also have special reporting rules. Dispositions of QOF interests generally must be reported on Form 1099-B, including dispositions by gift or inheritance, and each disposition is reported separately.
Form 1099-B may be required for such transactions:
For covered securities specifically, brokers would also need to report several additional details that help the recipient calculate gain or loss correctly.
Covered securities require more detail from the broker, including basis information. With noncovered securities, the broker can generally leave out the acquisition date, basis, accrued market discount, wash-sale loss, and short- or long-term classification when reporting the transaction separately.
Form 1099-B is not always needed for every broker transaction. There are exceptions which are quite common, like:
Barter exchanges also have separate exceptions. A Form 1099-B generally is not required when the exchange has fewer than 100 transactions during the year, when the transaction involves an exempt foreign person, or when the property or services exchanged are worth less than $1.
These are the main boxes to complete on Form 1099-B:
| Box | What it reports |
|---|---|
| Box 1a | Description of property |
| Box 1b | Date acquired |
| Box 1c | Date sold or disposed |
| Box 1d | Proceeds |
| Box 1e | Cost or other basis |
| Box 1f | Accrued market discount |
| Box 1g | Wash sale loss disallowed |
| Box 2 | Short-term or long-term gain or loss, or ordinary income |
| Box 3 | Collectibles or QOF indicator |
| Box 4 | Federal income tax withheld |
| Box 5 | Noncovered security checkbox |
| Box 6 | Whether the proceeds in Box 1d were reported to the IRS as gross or net |
| Box 7 | Check if loss not allowed based on amount in Box 1d |
| Box 12 | Check if basis reported to the IRS |
| Box 13 | Bartering |
The 2026 Form 1099-B includes a change to its address fields, while digital asset reporting also has an important update for 2026.
The payer and recipient address fields have been broken out into individual entry boxes on the 2026 form and instructions a formatting change that affects how data maps into filing software.
For 2026 digital asset sales, Form 1099-DA is generally the broker reporting form, not Form 1099-B. Brokers generally report basis for covered digital assets, but some IRS optional reporting methods allow brokers to omit acquisition date and basis. A digital asset does not go back to Form 1099-B just because it may also be treated as a security Form 1099-B applies only when a specific exception requires it.
The IRS now points filers to Publication 1099 for the general filing mechanics that apply to Form 1099-B electronic filing, corrected returns, recipient statements, TINs, backup withholding, and penalties rather than repeating them in the form-specific instructions.
For each Form 1099-B, you will need the following details:
Important: Most reportable transactions are entered separately. Some regulated futures, foreign currency, and Section 1256 option contracts, however, can be reported together on an aggregate basis.
Form 1099-B has separate deadlines for sending the recipient copy and filing with the IRS.
| Filing Type | Due Date |
|---|---|
| Recipient copy | February 16, 2027 |
| IRS paper filing | March 1, 2027 |
| IRS electronic filing | March 31, 2027 |
Recipient statements are usually due by February 15. In 2027, that date falls on a legal holiday in the District of Columbia, so the deadline moves to February 16.
Step 1: Add the payer and recipient details first. Include the account number if one is required.
Step 2: Add transaction information as this is where the sale details go proceeds, dates, withholding, and any basis or holding-period information that applies. QOF and noncovered security details should also be included where relevant.
Step 3: Check the return carefully for incorrect TINs, dates, proceeds, or box selections before it is filed.
Step 4: After the review is complete, file the return electronically. Recipient copies can then be managed or downloaded from the 1099Online account.
No. Form 1099-B does not have one minimum dollar amount that applies to every transaction. With Form 1099-B, whether filing is required depends mainly on what kind of transaction took place. Some transactions must be reported even if the amount is small. A few specific exceptions exist for example, certain fractional-share sales with proceeds under $20 may not need to be reported.
Form 1099-DA is generally used for digital asset sales, while Form 1099-B continues to cover other broker and barter exchange transactions. For 2026 sales, brokers must also report basis for covered digital assets on Form 1099-DA.
You usually cannot put several unrelated sales together on one Form 1099-B. Most transactions are reported separately. The exception is that certain types of contracts—such as regulated futures, certain foreign currency contracts, and Section 1256 options—can be combined and reported as one total.
The penalty depends on how late the return is filed. For 2027 filings, it can be $60, $130, or $340 per return. If the IRS finds that the filer intentionally ignored the filing requirement, the penalty is much higher and there is no overall maximum cap.
Watch for errors in proceeds, basis, acquisition dates, and holding-period reporting. It is also important to use Form 1099-DA instead of Form 1099-B when the transaction falls under the digital asset reporting rules.
