Final answer:
Clampett, Inc. does not have excess net passive income tax as its net passive income is negative.
Step-by-step explanation:
To calculate Clampett, Inc.'s excess net passive income tax, we need to determine the net passive income and apply the appropriate tax rate. Net passive income is calculated by subtracting the deductible expenses from the passive income. In this case, the passive income includes interest income and dividends ($60,000 + $40,000 = $100,000), and the deductible expenses include cost of goods sold ($150,000).
Net passive income = passive income - deductible expenses = $100,000 - $150,000 = -$50,000.
Since the net passive income is negative, there is no excess net passive income tax. The corporate tax rate of 21 percent is only applied to positive net passive income.
