Parts of Schedule D
Schedule D was revised to allow for entries from the new Form 8949 and changes made to Form 1099-B. Schedule D is used to report gain or loss on the sale of investment property and other capital gain distributions.
Schedule D is divided into three parts:
There can potentially be carryover losses, both short and long term (includible on Part I, line 6 and Part II, line 14) that must be considered before proceeding to Part III.
If the taxpayer's capital losses are more than the capital gains, claim a capital loss deduction on Form 1040, line 13. This deduction is limited to the lesser of $3,000 ($1,500 if Married Filing Separately) or the net loss as shown on Schedule D, line 16.
If there was a yearly net loss of more than $3,000, the unused part can be carried over to the next year and treated as if it were incurred in the next year. The losses retain their holding period status. This is covered in detail in the Capital Loss Carryovers topic.
