Answer:
Warranty Liability at December 31, 2018 = $2 million
Therefore,
The balance of deferred tax asset related to warranties:
= $2,000,000 × 40%
= $800,000
The balance of deferred tax asset related to warranties at December 31, 2017 is $840,000.
Therefore, the balance of deferred tax asset should be reduced by ($840,000 - $800,000) = $40,000.
Hence, the journal entry to record Lance's income tax provision for 2018 is as follows:
Income Tax expense A/c Dr. $34,040,000
To Deferred tax asset $40,000
To Income Tax payable ($85 million × 40%) $34,000,000
(To record income tax expense)
