Interest Tax Shields: Valuation Impact and Capital Structure Decisions

This is because the net effect of losing a tax shield is losing the value of the tax shield but gaining back the original expense as income. For depreciation, an accelerated depreciation method will also allocate more tax shield in earlier periods, and less in later periods. However, it is important to consider the effect of temporary differences between depreciation and capital cost allowance for tax purposes. An alternative approach called adjusted present value (APV) discounts interest tax shield separately. Even though the APV method is a bit complex, it is more flexible because it allows us to factor-in the risk inherent in admissibility of interest tax shield.

How To Calculate?

The applicable tax rate can vary depending on your location and the nature of your business. It’s important to use the current tax rate provided by your local tax authority or consult a tax professional to determine the correct rate. For instance, the interest deduction limit on student loans is $2,500 per year.

In this post, we’ll dive into a concept that is essential for understanding tax planning and its impact on businesses and individuals alike – the tax shield. 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.

This requires a forward-looking approach, anticipating future earnings and tax liabilities to ensure that debt is issued when it can provide the most significant tax relief. Moreover, the presence of interest tax shields can affect a company’s weighted average cost of capital (WACC). Since debt is generally cheaper than equity due to the tax deductibility of interest, incorporating more debt into the capital structure can lower the WACC. A lower WACC increases the present value of future cash flows, further boosting the company’s valuation. This dynamic creates a compelling case for strategic debt financing, especially in environments with favorable tax policies. The impact of interest tax shields is often reflected in the discounted cash flow (DCF) valuation model.

As a cost of borrowing, the borrower must make Interest payments for the benefit of borrowing. Private Equity Funds typically use large amounts of Debt to fund acquisitions. The Debt used in the purchase creates Interest Expense that reduces the acquired Company’s Tax bill. The Interest Tax Shield concept is highly relevant for Leveraged Buyout (‘LBO’) acquisitions executed by Private Equity firms. As you can see, the Taxes paid in the early years are far lower with the Accelerated Depreciation approach (vs. Straight-Line). With the two methods clarified, let’s look at the Cash Flow impact of each approach.

Since depreciation expense is tax-deductible, companies generally prefer to maximize depreciation expenses as quickly as they can on their tax filings. Corporations can use a variety of different depreciation methods such as double declining balance and sum-of-years-digits to lower taxes in the early years. The factor of (1-t) reduces the debt component which results in a lower WACC which in turn results in a higher present value of net cash flows. Properly using tax shields as allowed by law should not increase your chances of an audit.

It means using tax-deductible interest for lowering the total tax liability. The benefit of using depreciation with a tax shield is that you can subtract any depreciation expenses from taxable income. Since adding or removing a tax shield can be significant, many companies consider this when exploring an optimal capital structure. An optimal capital structure is a good mix of both debt and equity funding that reduces a company’s cost of capital and increases its market value. The good news is that calculating a tax shield can be fairly straightforward to do as long as you have the right information.

  • For instance, if your allowable interest tax cost is $2,000 and the effective tax rate is 25%, then your interest tax shield will be $500.
  • As we can see, Company A saved $660,000 on taxes due to its interest tax shield.
  • However, the interest here pertains to the interest payments, not the interest income, as most companies consider interest payments deductible expenses.

Tax shields can vary slightly depending on where you’re located, as some countries have different rules. Keep reading to learn all about a tax shield, how to calculate it depending on your effective tax rate, and a few examples. You have a little bit of flexibility with a tax shield since you have an opportunity to reduce taxable income for a specific tax year. Alternatively, you have the opportunity to move it customizing invoice title forward to a future point in time. Therefore, companies seek to maximize the tax benefits of debt without being at risk of default (i.e. failing to meet interest expense or principal repayment obligations on the date due). The statement holds true until the risk of default and bankruptcy outweighs the tax shield benefits, causing the capital structure of the company to likely be in need of debt restructuring.
