Whether you sold stocks, mutual funds, bonds, or other investments during the tax year, you may receive Form 1099-B, Proceeds From Broker and Barter Exchange Transactions. This tax form reports details about investment sales and certain barter exchange transactions, including proceeds from the sale and other information you may need when preparing your tax return. If you received Form 1099-B from a broker, financial institution, or barter exchange, it’s important to review the information carefully and use it to accurately report any capital gains or losses on your return.
What is a 1099-B?
Form 1099-B is a tax document that reports proceeds from broker and barter exchange transactions. It provides detailed information about the sale of stocks, bonds, mutual funds, and other securities, including:
- Date of the purchase
- Date of the sale
- Description of the item sold
- Total proceeds
- If your broker withheld any federal tax
If the cost basis of an asset is known, Form 1099-B will report this amount. Capital gains can affect how much tax you owe, so it is important to account for this form on your return.

Who should receive a 1099-B?
Brokers and barter exchanges will generate Form 1099-B for individual taxpayers who have reportable investment sales or transactions. If you sold stocks, bonds, mutual funds, exchange-traded funds (ETFs), or other securities through a broker during the year, you may receive Form 1099-B from your financial institution. The information on this form helps you accurately report capital gains and losses on your tax return.
You should typically receive Form 1099-B from your broker or financial institution by mid-February. The deadline for brokers to provide this form to you is January 31st. It’s important to note that while this is the general timeline, there might be exceptions or variations depending on specific circumstances or extensions granted by the IRS. Keep an eye on your mailbox, or check your online account with your broker to ensure timely receipt of Form 1099-B.
What are the 1099-B reporting requirements?
When it comes to reporting Form 1099-B, both the broker or financial institution who issued the form and the individual taxpayer have reporting obligations. The broker or financial institution is responsible for submitting a copy of the form to the IRS. As an individual taxpayer, you also need to report the information provided on Form 1099-B when filing your tax return. A broker or barter exchange is required to file this form for the following groups:
- Anyone who the broker sold stocks, commodities, mutual funds, or contracts on behalf of for cash
- Anyone who received stock, cash, or property from someone affiliated with the broker
- A person who used a barter exchange for property or services
Whether you have received Form 1099-B or not, you should track and review your investment activity to ensure all capital gains and losses are accounted for on your tax return.
Are there special reporting rules for barter exchanges?
Yes, there are special rules for barter exchanges when it comes to tax reporting. If you have exchanged goods or services without involving money, this is considered a barter exchange. The fair market value of the goods or services received through the barter exchange should be reported as income on your tax return.
Usually, when Form 1099-B reports a barter exchange, Box 13 will be filled out to indicate the fair market value of any goods or services exchanged in the transaction. This amount is considered income and is taxable.
How do I report Form 1099-B on my tax return?
If you receive Form 1099-B, first record any relevant information on Form 8949, Sales and Other Dispositions of Capital Assets, to calculate your capital gains or losses.
Information commonly needed from Form 1099-B includes:
- Description of the asset sold
- Date acquired
- Date sold
- Proceeds from the sale
- Cost basis
- Any wash sale adjustments
- Federal income tax withheld, if applicable
Then transfer that information to Schedule D, Capital Gains and Losses. Schedule D will give you your final adjusted gains or losses. This schedule should be attached to your Form 1040.
When you file with TaxSlayer, the program will automatically create the required forms and schedules after you’ve entered Form 1099-B.
What are short-term and long-term gains on Form 1099-B?
Box 2 on Form 1099-B will tell you whether your sale is a short-term or long-term gain. The gain is short-term if you owned an item for less than a year before selling it. Otherwise, the gain is long-term. This distinction between short-term and long-term sales is important because the taxes on long-term transactions are lower than those on short-term.
What should I do if I forget to report Form 1099-B on my tax return?
If you realize you still need to report Form 1099-B after filing your tax return, it’s important to take corrective action right away to avoid potential penalties and interest charges.
The IRS receives a copy of Form 1099-B from your broker or financial institution, so if you don’t include the form when you file, it can result in the IRS rejecting your return.
If the IRS accepts your return before you can include Form 1099-B, you must file an amended return using Form 1040-X. The amended return allows you to provide accurate information and make any necessary corrections. In this case, you only need to enter your 1099-B and resubmit your return.
