GG Inc. uses LIFO. GG disclosed that if FIFO had been used, inventory at the end of 2021 would have been $16 million higher than the difference between LIFO and FIFO at the end of 2020. Assuming GG has a 25% income tax rate:

In a situation where FIFO had been used, its reported net income for 2020 would have been $12 million higher than using LIFO for its financial statements.

The Ending Inventory of 2020 would have been $16 million higher in a case where FIFO had been used.

Hence, The Higher ending inventory will tend to means the lower cost of goods sold as well as the higher income which means that if FIFO had been used,the income of 2020 would have been higher by $16 million.

Income tax rate = 25%

The first step is to calculate for the Increase in Income tax expense

Using this formula to calculate for the Increase in Income tax expense

Increase in Income tax expense = Increase in Income x Income tax rate

Let plug in the formula

Increase in Income tax expense= 16 x 25%

Increase in Income tax expense= $4 million

The second step is to calculate for the Increase in Income net income

Using this formula

Increase in net income = Increase in income - Increase in Income tax expense

Let plug in the formula

Increase in net income = 16 - 4

Increase in net income = $12 million

Therefore in a situation where FIFO had been used, its reported net income for 2020 would have been $12 million higher than using LIFO for its financial statements.
