Form 8949 (2016) – Sales And Other Dispositions Of Capital Assets
Purpose of Form 8949
Form 8949 reports all capital asset sales and dispositions in 2016, organized by holding period and basis-reporting status to the Internal Revenue Service. The 2016 version introduced mandatory basis-status sorting through Boxes A through C for short-term transactions and Boxes D through F for long-term transactions, aligning with broker Form 1099-B reporting. Long-term transactions with an IRS-reported basis may be bypassed entirely and posted directly to Schedule D, line 8a.
Filing Steps for 2016
You must determine the holding period classification by measuring from the acquisition date through the sale or disposition date in 2016. Short-term transactions include assets held for one year or less, while long-term transactions include assets held for more than one year. Apply this distinction separately to Part I for short-term transactions and Part II for long-term transactions.
Obtain Form 1099-B or substitute statements from all brokers, as these documents indicate whether the basis was reported to the IRS. In 2016, brokers began standardized reporting of cost basis. Review the legend for Box 1a to confirm the basis-reporting status before selecting your checkbox.
Short-Term Transaction Boxes
For Part I short-term transactions, select only one of Boxes A, B, or C. Box A covers Form 1099-B transactions with IRS-reported basis and no adjustments needed. Box B covers Form 1099-B transactions where the basis was not reported to the IRS. Box C covers transactions not on any Form 1099-B. If you have transactions spanning multiple boxes, file separate Form 8949, page 1, for each box, with one box checked.
Long-Term Transaction Boxes
For Part II long-term transactions, select only one of Boxes D, E, or F using the same basis-reporting logic as short-term transactions. The 2016 instructions permit you to aggregate and report long-term Box D transactions directly on Schedule D line 8a without filing Form 8949 for those rows when the Form 1099-B shows the basis was reported to the IRS, and you have no adjustments.
Column Completion Requirements
Complete columns (a) through (h) for each transaction row with specific information. Column (a) requires a description of the property, such as "100 sh. XYZ Co." Enter acquisition and sale dates in MM/DD/YYYY format in columns (b) and (c). Proceeds, which represent the gross sale price, belong in column (d). Cost or other basis goes in column (e). Adjustment codes and amounts appear in columns (f) and (g) only if the basis, gain, or loss requires correction from the Form 1099-B.
Calculate gain or loss in column (h) by subtracting column (e) from column (d), then adding or subtracting column (g). Report the result in column (h) with appropriate sign notation. If the result shows a loss, use parentheses or a negative symbol.
Totals and Schedule D Transfers
Complete the Totals row on line 2 of each part by summing columns (d), (e), (g), and (h). Transfer totals according to the form instructions, specifying the line destinations—short-term totals from Box A transfer to Schedule D line 1b. Box B amounts transfer to Schedule D line 2. Box C amounts transfer to Schedule D line 3.
Long-term totals from Box D transfer to Schedule D line 8b. Box E amounts are transferred to Schedule D, line 9. Box F amounts transfer to Schedule D line 10. Verify your Social Security Number or taxpayer identification number appears at the top of page 2. Attach both pages of Form 8949 to Schedule D before filing with your 2016 tax return.
Year-Specific Updates for 2016
The 2016 tax year marked the broader implementation of uniform basis-reporting standards by the IRS and brokers, tied to Form 1099-B boxes. Filers must match the transaction checkboxes (A through F) directly to the broker statements. Instructions emphasized verifying Form 1099-B Box 1a legend before filing to ensure proper classification.
Eligible long-term transactions meeting Box D criteria can be reported as totals only on Schedule D, line 8a, eliminating the requirement to list each transaction on Form 8949, page 2. This streamlines compliance for passive investors holding securities with IRS-reported basis and no adjustments needed.
Basis Adjustment Guidance
The 2016 instructions clarified that if the Form 1099-B basis was incorrect, filers must enter the basis as reported to the IRS in column (e) and post a correction amount in column (g) with the appropriate code. This requirement prevented double-reporting of basis differences and ensured proper reconciliation between taxpayer records and IRS information.
Instructions explicitly cross-referenced Form 1099-B Box 1a language and substitute statement equivalence to help filers correctly select checkboxes A, B, C, D, E, or F. This guidance reduced the misclassification of transactions and improved the accuracy of matching broker reporting to tax return reporting.
The 2016 tax year did not introduce temporary or disaster-related adjustment codes. The standard code set from prior years remained in effect for all adjustment situations.
Schedule D Integration
Instructions restated precise line-number destinations on Schedule D for each checkbox outcome. This clarification emphasized that Form 8949 serves only as an attachment and must be filed with Schedule D. The specific line mapping ensures the proper flow of capital gain and capital loss information from detailed transaction reporting to summary schedules, maintaining accuracy in completing Form 8949 and the overall capital gains reporting process.
