Final answer:
a. The after-tax cost of the interest expense to the Sanchezes in 2023 is $19,040. b. The after-tax cost of their rental payments in 2023 is $21,000. c. The after-tax cost of their 2023 interest expense is $28,000.
Step-by-step explanation:
a. What is the after-tax cost of the interest expense to the Sanchezes in 2023?
To calculate the after-tax cost of the interest expense, we need to determine the deductible interest and apply the Sanchezes' marginal tax rate. The deductible interest is the interest expense on the loan for the first five years, which is $400,000 x 7% = $28,000 per year. Since they would itemize deductions, the after-tax cost of the interest expense is calculated as follows:
After-tax cost = Deductible interest x (1 - Marginal tax rate)
= $28,000 x (1 - 0.32)
= $19,040
b. What is the after-tax cost of their rental payments in 2023?
The after-tax cost of the rental payments is calculated by subtracting the tax savings from the rental payments. Since they would not have any deductible interest, the tax savings would be zero. Therefore, the after-tax cost of their rental payments is equal to the total rental payments:
After-tax cost = Rental payment
= $21,000
c. What is the after-tax cost of their 2023 interest expense?
Since the interest expense is their only itemized deduction, the after-tax cost is the same as the deductible interest. The deductible interest is $28,000 per year for the first five years, so the after-tax cost of their 2023 interest expense is $28,000.
