Final answer:
The total income tax expense on the consolidated income statement for this period is $6,720.
Step-by-step explanation:
To calculate the total income tax expense on a consolidated income statement, we need to consider the cash dividend paid by Ake and the distribution made by Boxwood, as well as the intra-entity gross profits carried in Lake's beginning and ending inventory.
First, we calculate the taxable income for Lake and Boxwood. Lake's taxable income will be its share of the intra-entity gross profits in its ending inventory, which is 60% of $32,000 or $19,200. Boxwood's taxable income will be the remaining 40% of $32,000 or $12,800.
Next, we calculate the income tax expense for Lake and Boxwood using the effective tax rate of 21%. Lake's income tax expense will be 21% of $19,200, which is $4,032. Boxwood's income tax expense will be 21% of $12,800, which is $2,688.
Finally, we sum up the income tax expenses for Lake and Boxwood to get the total income tax expense on the consolidated income statement. The total income tax expense is $4,032 + $2,688 = $6,720.
