Answer: interest tax shield
Explanation: A tax shield is a reduction in taxable income for an individual or corporation achieved through claiming allowable deductions such as mortgage interest, medical expenses, charitable donations, amortization, and depreciation .
The term “interest tax shield” refers to the reduced income taxes brought about by deductions to taxable income from a company’s interest expense. For instance, there are cases where mortgages may have an interest tax shield for buyers since the mortgage interest is deductible against income. One of the main objectives of companies is to reduce their tax liability as much as possible. Interest tax shields encourage firms to finance projects with debt, since the dividends paid to equity investors are not deductible.
