The term “Tax Shield” refers to the deduction allowed on the taxable income that eventually results in the reduction of taxes owed to the government.

Though tax shields are an important tactic, there is no consensus regarding the correct way to compute their value. Most authors think of calculating the value of the tax shield in terms of the appropriate present value of the tax savings due to interest payments on debt. The Tax Shield Formula is a tool utilized in finance to calculate the amount a company can save on its taxable income by taking its deductible expenses into account. It’s computed by multiplying the deductible expenses by the income tax rate.
