Form 8949.   Many transactions that, in previous years, would have been reported on Schedule D must be reported on Form 8949, Sales and Other Dispositions of Capital Assets. For 2012, Schedule D (Form 1120S) filers will not list separate capital asset transactions on Schedule D (Form 1120S). Instead, Schedule D (Form 1120S) filers that have transactions that must be listed on line 1, 2, 3, 8, 9, or 10 must complete Form 8949 before completing line 1, 2, 3, 8, 9, or 10. See the Instructions for Form 8949.
