Answer:
deferred income tax benefit during 2018: 6,700
deferred income tax liability ending balance 27,400
Explanation:
beginning deferred tax laibility 34,000
this will change to 21,000 for the tax rate change
(100,000 x 21% = 21,000)
thus there is a decrease of 13,000 in the tax liablity
Then:
book income 400,000
temporary differenc(net): (30,000)
Taxable income 370,000
30,000 x 21% = 6,300 additional deferred tax expense
13,000 benefit - 6,300 deferred tax expense = 6.700 benefit
