Answer:
$4,000 is treated as a capital gain and then reduced by the un-offset net losses in 2016 ($300) and 2017 ($100) to arrive at net capital gain of $3,600 ($4,000 - 300 - 100). $0 of the amount is treated as an ordinary income.
Step-by-step explanation:
Section 1231 gain arises when an asset (real property or depreciable business property) is sold for more than its current tax basis. The gain is regarded as a capital gain and taxed at the lower capital gain rates and not as ordinary income.
Section 1231 property are assets used in trade or business and held by the Taxpayer for more than one year. A gain on the sale of Section 1231 business property is treated as a long-term capital gain.
