Answer:
$12,000
Explanation:
30%×$40,000= $12,000
Brass Co.'s 2017 taxable income of $60,000 exceeds the $40,000 net operating loss carry forward from 2016.
Therefore the total net operating loss carry forward can be utilized in 2017 in which $40,000 carryforward will be used to offset $40,000 of Brass' taxable income.
