Final answer:
Using the formula for deferred income tax expense or benefit, the company's deferred income tax expense or benefit is $87,150.
Step-by-step explanation:
To calculate the deferred income tax expense or benefit, we need to determine the temporary differences between book income and taxable income. In this case, the temporary difference is the difference between tax depreciation and book depreciation, which is $415,000. We also need to consider the tax-exempt municipal bond interest income of $375,000.
We can calculate the deferred income tax expense or benefit using the formula:
Deferred Income Tax Expense/Benefit = Temporary Difference * Tax Rate
Deferred Income Tax Expense/Benefit = $415,000 + $375,000 * 0.21
Deferred Income Tax Expense/Benefit = $87,150
