Final answer:
a. The after-tax cost of the interest expense to the Sanchezes in 2019 is $23,654.40. b. The after-tax cost of their rental payments in 2019 is also $23,654.40. c. The after-tax cost of the 2019 interest expense is $23,654.40.
Step-by-step explanation:
a. To calculate the after-tax cost of the interest expense in 2019, we need to find the deductible interest. Since the Sanchezes itemize deductions, we can include the deductible interest. The deductible interest for the first five years is the annual interest expense, which is 7% of the loan amount. So, the deductible interest is $496,000 × 7% = $34,720.
Therefore, the after-tax cost of the interest expense is the deductible interest minus the tax savings. The tax savings are the deductible interest multiplied by the marginal tax rate. So, the after-tax cost of the interest expense is $34,720 - ($34,720 × 32%) = $23,654.40.
b. To calculate the after-tax cost of the rental payments in 2019, we can consider the rental payments as an expense. The after-tax cost of the rental payments is the rental payments minus the tax savings. The tax savings are the rental payments multiplied by the marginal tax rate. So, the after-tax cost of the rental payments is $34,720 - ($34,720 × 32%) = $23,654.40.
c. Assuming the interest expense is the only itemized deduction for the year, the after-tax cost of the 2019 interest expense can be calculated using the same formula as in part a. The deductible interest is $34,720 and the marginal tax rate is 32%. So, the after-tax cost of the interest expense is $34,720 - ($34,720 × 32%) = $23,654.40.
