Answer:
We have to assume specific tax rate to come up with the income tax expenses. Let assume the tax rate is 30%.
The income tax expense in year 2: $53,400.
Explanation:
We have:
Depreciation expenses of the equipment in the second year = (Initial cost - salvage value) / Useful life = (168,000 - 0)/4 = $42,000.
Profit before tax in year 2 = Sales in year 2 - operating expenses in year 2 - Depreciation expenses in year 2 = 520,000 - 300,000 - 42,000 = $178,000.
Income tax expense in year 2 = Profit before tax in year 2 x tax rate = 178,000 x 30% = $53,400.
So, the answer is $53,400.
