I am reporting capital losses for the first time in 2016. I have just over $6000 in losses resulting from stock sales.

Since one sale alone accounted for a loss of $3000, do I need to list all my other transactions on Form 8949? or can I ignore them?

Many thanks.

Generally, report capital gains and losses on Form 8949. Complete Form 8949 before you complete line 1b, 2, 3, 8b, 9, or 10 of Schedule D (Form 1040)I guess you are
aware you can carry it forward capital losses over $3000 to future tax years. The remaining $3K in losses would carry forward to 2017. Say, With $2K in 2017 gains and $3K in carry forward losses, you would have a net 2017 loss of $1KOf that, you would get the tax benefit of $1K against earned or other types of income in a given year. in 2017; Any excess capital loss can be carried over until you die, then it is lost and of no benefit to your estate or heirs.
