What is Form 1099-B?
Form 1099-B is an IRS tax form used to report the sale or exchange of securities, stocks, bonds, commodities, or other financial instruments. The form is typically issued by brokers, mutual funds, or other financial institutions that facilitate these transactions. Form 1099-B provides essential details about the transaction, including the proceeds from the sale, the cost basis (if available), and whether the sale resulted in a gain or loss. This information is necessary for taxpayers to accurately report their capital gains and losses on their income tax returns.
Form 1099-B is primarily used by individuals who engage in investment activities, such as buying and selling stocks, bonds, or other securities. Brokers or financial institutions are required to provide this form to both the IRS and the taxpayer whenever there is a reportable transaction. The form helps ensure that taxpayers are aware of their tax obligations related to these transactions and report them correctly on their annual tax returns.
Deadline for 1099-B 2025
The deadline for filing Form 1099-B for the 2025 tax year is February 28, 2026, if filing on paper, and March 31, 2026, if filing electronically. Financial institutions and brokers are required to send Form 1099-B to taxpayers by January 31, 2026. This form provides taxpayers with the necessary information to report their capital gains and losses accurately on their tax return. If January 31 falls on a weekend or holiday, the deadline for providing the forms to recipients is extended to the next business day.
The IRS requires that brokers and other financial institutions also submit the form electronically or by paper by the appropriate deadlines. Failure to meet these deadlines could result in penalties for late filing, so it is important to adhere to the guidelines and ensure the form is filed in a timely manner.
Who Must File a 1099-B?
Form 1099-B must be filed by any broker, barter exchange, or other financial institution that facilitates the sale or exchange of securities, stocks, bonds, or other capital assets. These entities are required to issue the form to the IRS and the taxpayer when a reportable transaction has occurred. A reportable transaction typically involves the sale, exchange, or transfer of securities that result in a taxable event, such as a capital gain or loss.
For example, if you sell stocks through a brokerage, the brokerage firm will issue a Form 1099-B detailing the sale price, purchase price, and any gain or loss. Similarly, mutual funds, barter exchanges, and other financial institutions are required to issue Form 1099-B for transactions involving commodities, bonds, or other capital assets. It is important for taxpayers to understand that if they have multiple transactions, they may receive multiple 1099-B forms from different brokers or financial institutions.
In cases where the taxpayer is involved in transactions outside of traditional stock exchanges or mutual funds, such as private sales or barter transactions, the party facilitating the transaction (such as a barter exchange) must file Form 1099-B to report the sale. This form is necessary to ensure accurate tax reporting and to allow taxpayers to report their capital gains or losses correctly on their tax returns.

Step 1: Understand Who Must File
Before filing, ensure that you are required to file Form 1099-B. Generally, brokers, mutual funds, and other financial institutions that facilitate the sale of securities, stocks, bonds, or commodities must file this form for reportable transactions. Reportable transactions usually involve capital assets, where the sale or exchange results in a taxable gain or loss. If your institution or company is involved in such transactions, you must file Form 1099-B.
Step 2: Register with the IRS e-File System
To file Form 1099-B electronically, you must register with the IRS e-file system. This can be done by visiting the IRS website and enrolling in the Filing Information Returns Electronically (FIRE) system. The registration process requires submitting your business details, including the Employer Identification Number (EIN), and may take a few weeks to process. Once you are registered, you will receive approval to file forms electronically.
Step 3: Prepare the Data File
Form 1099-B must be filed in a specific electronic format that complies with IRS specifications. Most brokers and financial institutions will use tax preparation software or third-party services to generate the required file. The data file should include information such as:
- Payer’s and recipient’s names, addresses, and Taxpayer Identification Numbers (TINs)
- Description of the securities or assets sold
- Sale proceeds and cost basis
- Capital gains or losses from the sale
- Any other relevant transaction details
It’s important that the data file is formatted correctly to avoid errors or rejections from the IRS system.
Step 4: Submit the File
Once the file is prepared, you can submit it through the IRS e-file system (FIRE). To do this, log into your registered account, upload the data file, and submit the form electronically. The IRS will validate the data, and you will receive an acceptance or rejection notification. If the submission is accepted, you will receive confirmation from the IRS that the form has been filed successfully.
Step 5: Provide Copies to Recipients
After filing Form 1099-B electronically with the IRS, you must provide a copy to each recipient by January 31, 2026. This allows the taxpayer to report their capital gains or losses on their income tax return. Ensure the form is provided on time to avoid penalties.
Step 6: Correcting Errors
If you discover any errors after filing Form 1099-B, you must submit a corrected form. This can be done by submitting a new form with the corrected information, clearly indicating that it is a correction. Be sure to notify the recipient of the error and provide them with the corrected form.
Step 7: Filing Deadline
The deadline for filing Form 1099-B electronically is March 31, 2026, for the 2025 tax year. Make sure to meet this deadline to avoid penalties for late filing. If submitting on paper, the deadline is February 28, 2026.
By following these steps, you can ensure that your Form 1099-B filing is accurate and timely.
Form 1099-B: Tax Reporting Pointers
Form 1099-B is essential for reporting the sale or exchange of securities and other financial assets, ensuring that taxpayers accurately report their capital gains or losses. Here are some key tax reporting pointers for Form 1099-B:
1. Understanding Capital Gains and Losses
When you sell or exchange a capital asset, such as stocks, bonds, or other securities, the IRS requires you to report the sale’s proceeds and cost basis. The difference between the proceeds (the amount received from the sale) and the cost basis (the original purchase price, adjusted for certain factors) determines whether you have a gain or a loss.
If the sale results in a gain, you may need to pay taxes on the gain, depending on your income level and how long you held the asset. If the sale results in a loss, you may be able to use the loss to offset other capital gains or reduce your taxable income.
2. Cost Basis Reporting
Cost basis is a key element in calculating capital gains or losses. If you received Form 1099-B, it may report both the sale proceeds and the cost basis of the asset. In many cases, brokers will report this information on the form, but you may need to adjust the cost basis if you have made improvements to the asset or if you have certain transactions, such as reinvested dividends.
If the form does not report the cost basis, it is your responsibility to calculate it based on your records. Accurate reporting of cost basis is crucial to avoid errors in your tax return.
3. Short-Term vs. Long-Term Capital Gains
One of the most important factors in determining your tax rate on capital gains is how long you held the asset before selling it. Assets held for one year or less are considered short-term, while those held for more than one year are considered long-term. Short-term capital gains are generally taxed at your ordinary income tax rate, while long-term capital gains are taxed at a lower rate, ranging from 0% to 20%, depending on your income.
Ensure that you report both short-term and long-term capital gains accurately to avoid unnecessary taxes.
4. Multiple Transactions
If you have multiple transactions reported on Form 1099-B, it’s important to track each one separately. The IRS requires that each transaction be reported on your tax return, whether it results in a gain or a loss. You can use Schedule D (Capital Gains and Losses) to report the total of your capital gains and losses for the tax year.
5. Correcting Mistakes on Form 1099-B
If you find errors on your Form 1099-B, you must contact the broker or financial institution that issued the form. They will issue a corrected form if necessary. If you have already filed your tax return, you may need to file an amended return to correct any discrepancies in your capital gains or losses.
By carefully following these tax reporting pointers and using Form 1099-B to report your securities transactions accurately, you can ensure compliance with IRS regulations and minimize the risk of errors on your tax return. If you have complex transactions or are unsure about any aspect of the reporting process, it’s advisable to consult with a tax professional.
