Receiving a Form 1099-B can feel confusing, especially if you are new to trading or investing. This document reports the transactions that led to gains or losses, and it plays a direct role in the taxes you owe. Understanding what a 1099-B looks like and how to read the numbers helps you file accurately and avoid surprises during tax season.
Basic Purpose of the 1099-B
The IRS requires brokers and financial platforms to send you a 1099-B so you can report sales or exchanges of investments. It captures details like the date of sale, the proceeds you received, and the cost basis of what you sold. Without this form, you would have to reconstruct every trade from memory, which increases the risk of errors.
Where You Typically Get the Document
You will usually receive a 1099-B from your brokerage, robo-advisor, or cryptocurrency exchange by the end of January. If you use multiple platforms, you might get more than one form, one for each account. It is important to compare these with your own records to confirm that every sale appears correctly before you file your return.
Key Sections on the Form
Looking at a printed or digital 1099-B, you will see blocks of information organized into clear sections. The top identifies the payer and your personal details, such as your name and address. Below that, the form divides into boxes and codes that specify the type of transaction, the dates of acquisition and sale, and the amounts used to calculate your gain or loss.
Data Rows for Each Transaction
Each trade you make that qualifies for a 1099-B gets its own row, or in some cases, groups of rows if the transactions are similar. These rows typically include the date you acquired the security, the date you sold it, the proceeds from the sale, and your cost basis. Some forms also show whether the security was held long-term or short-term, which affects your tax rate.
Next to the numerical data, you will find checkboxes or a box for code letters. These indicate how the IRS should treat the transaction for tax purposes. For example, one code might represent a covered security sale, while another might apply to a non-covered security or to transactions in regulated investment vehicles. Reviewing these codes ensures that your tax software or preparer applies the correct rules.
Common Variations Across Brokers
Different brokers format their 1099-B documents in slightly different ways, but the core data remains the same. Some platforms use a table with columns for date acquired, date sold, description, proceeds, and cost basis, while others stack this information in a more linear layout. Cryptocurrency exchanges may include additional details like wallet addresses or transaction IDs to help you track specific trades.
What to Do After You Review the 1099-B
Once you have the form, match every sale on the 1099-B with your own records or export from your trading platform. Look for any missing transactions or discrepancies in proceeds and basis. If everything aligns, you can move the figures into your tax return or tax software. If you find errors, contact your broker for a corrected statement before you file, since adjustments after filing can be more complicated.
