Final answer:
To calculate the company's current income tax expense or benefit, subtract the tax depreciation from the pretax book income and add the tax-exempt municipal bond interest. Finally, apply the appropriate tax rate to the taxable income.
Step-by-step explanation:
To calculate the company's current income tax expense or benefit, we need to consider the tax depreciation and book depreciation difference, as well as the tax-exempt municipal bond interest.
First, we calculate the taxable income by subtracting the tax depreciation from the pretax book income: $610,000 - $520,000 = $90,000.
Next, we add the tax-exempt municipal bond interest to the taxable income: $90,000 + $255,000 = $345,000.
Finally, we calculate the income tax expense or benefit by applying the appropriate tax rate to the taxable income. The tax rate will depend on the jurisdiction and the company's tax rate for the current year.
