## What is the interest tax shield?

The interest tax shield is a saving from the tax deduction due to interest expense from the debt payments. The costs of the debt decreases the taxable income which results in lower tax liabilities.

Note that interest expenses are tax-deductible, while dividends to equity holders are not tax-deductible. That’s why debt is often a cheaper source of financing a business than rising money from investors.

Since tax benefits from debt payments have a significant impact on the cost of rising capital it is always considered while calculating the weighted average cost of capital (WACC).
