What Is Form 8949?

Form 8949 is used to report individual sales of capital assets — each sale of a stock, fund, or other investment gets its own line. You list the asset, dates acquired and sold, proceeds, cost basis, and any adjustments (like wash sale disallowances). The totals flow to Schedule D. If your broker reported all transactions on your 1099-B with the correct basis, you may be able to skip detailed listing and use summary totals instead. Always reconcile your Form 8949 against your 1099-B carefully.
