How to Report 1099-B on Your Tax Return

Form 1099-B plays a crucial role for taxpayers involved in stock, bond, or other security transactions. It provides essential information to accurately report capital gains and losses on tax returns. Understanding how to incorporate this form into your filing process ensures compliance with IRS regulations and helps optimize tax outcomes.

Identification of 1099-B Key Details

Form 1099-B is issued by brokers or barter exchanges to report proceeds from security sales, which are used to calculate capital gains or losses. It includes details such as the date of acquisition and sale, the type of security, and the cost basis. The cost basis determines the taxable gain or loss. For instance, if you bought shares at $50 each and sold them at $70, the gain would be $20 per share.

This form also specifies whether the gain or loss is short-term or long-term, which impacts tax rates. Short-term gains are taxed at ordinary income rates, while long-term gains benefit from reduced rates of 0%, 15%, or 20%, depending on income. Adjustments for wash sales—when a security is sold at a loss and repurchased within 30 days—are also noted. These adjustments defer recognition of the loss and affect taxable income.

Applicable Forms and Schedules

Reporting Form 1099-B requires familiarity with Schedule D (Form 1040) and Form 8949. Schedule D summarizes all capital asset sales and categorizes them as short-term or long-term, directly affecting tax liability.

Form 8949 itemizes each transaction, including acquisition and sale dates, proceeds, and adjusted cost basis. Adjustments, such as wash sales, must be documented. Totals from Form 8949 are carried over to Schedule D, and accuracy is critical to avoid discrepancies and potential IRS scrutiny.

Calculating Gain or Loss

Calculating gains or losses depends on the difference between the selling price and the adjusted cost basis. The adjusted cost basis includes purchase price and any related fees. For example, if shares were sold for $10,000 but purchased for $8,000 with $100 in fees, the gain would be $1,900.

The holding period determines whether the gain or loss is short-term or long-term. Assets held for a year or less are short-term and taxed at ordinary income rates, while those held longer qualify for preferential long-term rates of 0%, 15%, or 20%, depending on income.

Entering Figures on Your Return

Entering figures from Form 1099-B into your return begins with Form 8949, which requires precise transaction details. Each entry must match broker-provided documentation to avoid errors that could trigger IRS scrutiny.

Totals from Form 8949 are summarized on Schedule D, separating short-term and long-term transactions. This classification affects tax rates and strategies like tax-loss harvesting, where losses offset gains to reduce taxable income. Properly following IRS guidelines ensures compliance and maximizes tax efficiency.

Adjustments for Special Transactions

Certain transactions require adjustments for accurate reporting. Understanding these scenarios is essential for compliance.

Wash Sales

A wash sale occurs when a security is sold at a loss and repurchased within 30 days before or after the sale. The loss is disallowed for immediate deduction and added to the cost basis of the repurchased security, deferring recognition until the new security is sold. For example, if a $500 loss on shares of XYZ Corporation is disallowed due to a wash sale, the $500 is added to the cost basis of the new shares. Taxpayers must track these adjustments, as brokers may not always report them.

Corporate Actions

Corporate actions such as mergers, stock splits, or dividend payments in shares can affect cost basis calculations. For example, a stock split increases the number of shares while reducing the cost basis per share, though the total investment value remains unchanged. Similarly, mergers may require recalculating the cost basis if shares are exchanged, and potential gains may need to be recognized depending on the transaction. Taxpayers should rely on information from corporations or advisors to ensure accurate reporting and compliance.
