Step-by-step explanation:
1. Calculation to for the effect of the change as well as the preparation of the journal entry to record the income tax expense in 2016.
Based on the information given the effect of the change is that the deferred tax liability will have to be revised in order for it to show the current tax rate.
First step is to calculate the Deferred tax liability using this formula
Deferred tax liability =(Deferred tax liability temporary difference amount× Change in tax rate)
Let plug in the formula
Deferred tax liability ($20 million x [40% - 30%]) Deferred tax liability=($20 million ×10%)
Deferred tax liability=$2
Second step is to calculate for the income tax payable using this formula
Income tax payable =(Taxable income× Tax rate)
Let plug in the formula
Income tax payable=($30 million x 40%)
Income tax payable= $12
Last step is to know the income tax expense using this formula
Income tax expense = Amount of Income tax payable-Deferred tax liability amount
Let plug in the formula
Income tax expense =$12-$2
Income tax expense =$10
JOURNAL ENTRY on record income tax expenses
DR Income tax expense $10
DR Deferred tax liability$2
CR Income tax payable $12
2. Based on the information given NO adjustment will be made in order to revise the retained earnings because in a situation where a previous estimate is been revised the financial statements will not be revised which inturn means that no further adjustments will be made to the current accounts.
