What IRS Form 8949 Is For
IRS Form 8949 (2023) is used to report the sale or exchange of capital assets, such as stocks, real estate, digital assets, or other investments. It provides the Internal Revenue Service with a detailed list of each transaction, showing your sales price, cost basis, and resulting capital gain or loss. The form works in conjunction with Schedule D, which summarizes your total capital gains and losses on your tax return. By listing every sale, Form 8949 helps you accurately report income, verify information from Form 1099-B, and calculate your capital gains tax or capital losses in accordance with current tax law.
When You’d Use IRS Form 8949
You must file IRS Form 8949 whenever you sell or exchange a capital asset during the tax year. This includes stocks, bonds, mutual funds, cryptocurrencies, NFTs, and real estate transactions.

Key Rules and Details for 2023
When completing IRS Form 8949, it’s essential to understand the key rules that affect how you report capital gains and losses for tax purposes. The following points highlight important details for accurate filing:
- Transaction Type: Each sale must show the purchase price, sales price, and fair market value to determine whether it resulted in a short-term capital gain or a long-term capital gain.
- Tax Impact: Your holding period determines the tax rate and how your taxable gain or net capital loss affects your overall tax bill.
- Broker Reports: Brokerage firms provide Form 1099-B and other tax forms to help both you and the IRS verify transaction details.
- Cost Basis Methods: Many brokerage firms use average cost basis, adjusted cost basis, or other cost basis methods to track investments and calculate the cost basis from the original cost.
- Adjustments: Use more than one code if needed to correct for stock splits, reinvested dividends, wash sales, or charitable contributions.
- Exceptional Cases: Report eligible gain from a qualified opportunity fund or long-term transactions reported after an original owner’s death at the proper fair market value or lower price.
- Professional Help: A tax professional can offer valuable guidance on fulfilling tax obligations, claiming tax deductions, and ensuring compliance with income tax requirements.

Common Mistakes and How to Avoid Them
Filing IRS Form 8949 can be confusing, and even minor errors may affect your taxable income or capital gains tax. Here are common mistakes and how to prevent them:
- Mismatch with broker reports: Always compare your entries with Form 1099-B to ensure the numbers match exactly.
- Incorrect checkboxes: Review the instructions before selecting boxes A–F so each sale appears in the correct category.
- Omitting digital asset transactions: Treat all crypto or NFT sales as taxable events and include them with your capital assets.
- Using the wrong cost basis: Double-check your cost basis for splits, dividends, or reinvestments, and verify any adjustments.

What Happens After You File
After you file IRS Form 8949, the Internal Revenue Service reviews your entries to ensure that each sale and adjustment is correctly reported. The IRS verifies the appropriate part of your return by matching what you entered with data from brokers and financial institutions. This includes checking any applicable code notes, verifying the proceeds from sold shares, and reviewing special rules under the Jobs Act that may affect reporting for individual taxpayers.
Your totals also factor into how your taxable income and income tax are calculated. If the IRS identifies discrepancies in your figures or the original investment, they may send a notice requesting clarification. In some cases, adjustments may be needed to reflect an abbreviated symbol or to confirm that the reported gain or loss follows the correct treatment for the year filed.
