Understanding Original Issue Discounting: A Comprehensive Approach

In finance, especially in fixed-income securities, a concept called original issue discount (OID) plays an important role. OID is a priority for issuers of debt securities and investors, offering exceptional benefits and potential tax advantages. Understanding OID is key for institutions investing in the bond market, corporations financing their operations, and individuals investing in fixed-income instruments.

The Basics of Original Issue Discounting

At its most basic, original redemption discount refers to the difference between a bond's par value (or face) and its original issue price when the bond was first issued. This discount represents additional interest earned by the investor, over and above regular coupon payments. It occurs in zero-coupon bonds, which are offered at a steep discount and do not pay periodic interest, and can also be found in bonds with coupon rates lower than the prevailing market rate. Companies may issue bonds at a discount for several reasons. For example, market conditions may create lower demand for the bond at its face value, or the issuer may need to offer a discount to attract investors. In some cases, issuing bonds at a discount could be a viable option for companies looking to manage their cash flow.

Tax Implications for Investors

For investors, the OID presents a unique tax situation. In the United States, the IRS treats the discount as interest income, which accrues over the life of the bond, regardless of the bond's payment structure. This means that investors are liable for taxes on this accrued income annually, even though they might not receive the cash until maturity. It’s a concept known as "phantom income," and it can catch unsuspecting investors off-guard if they're not prepared for the tax implications.

However, while there may be increased jitters when investing during an election year, the impact on long-term investments is often minimal. As measured by the CBOE Volatility Index, or the VIX, market volatility ended 2020 at 22.75, just a tad higher than the historical average of 21—even as the world was recovering from the global pandemic.3

Calculating Original Issue Discount

The OID is generally straightforward to calculate but requires an understanding of the bond terms, including the difference between the face value of the bond and the issue price. For tax purposes, the IRS provides tables and methods for calculating the amount that is subject to tax each year, which can be complicated to calculate for long-term mortgages.

The Benefits and Drawbacks for Investors

Investing in bonds with OID can be profitable. Recognizing progressive income for tax purposes can be advantageous, especially if the investor is in a lower tax bracket in the future. Additionally, buying these bonds at a discount means there’s the potential for a higher yield compared to bonds bought at par. However, it does include accrual taxes, which can be problematic for liquidity. Additionally, market risk increases as interest rates rise, as a bond’s price may fall below its discounted offer price.

Corporate Finance Strategies Involving OID

From a corporate finance perspective, issuing bonds at a discount can be a strategic tool. Companies might issue such bonds to improve liquidity without the immediate cash outflow of interest payments. This can be particularly appealing during periods of tight cash flow or when a company is undertaking significant investments or expansions.

OID in the Context of Zero-Coupon Bonds

The most straightforward example of OID is seen in zero-coupon bonds. These bonds are issued at a significant discount and don’t pay periodic interest. Instead, the investor receives the face value at maturity. Zero-coupon bonds can be an attractive option for long-term investment strategies, especially for retirement planning or funding future expenses like college tuition, where the investor does not require immediate income but is focused on growth over time.

OID and Market Dynamics

The dynamics of OID bonds in the market can be influenced by various factors, including changes in interest rates, the issuer's credit rating, and overall market conditions. Understanding these dynamics is crucial for investors to make informed decisions.

Regulatory Considerations and Reporting Requirements

Regulatory bodies closely monitor the issuance and trading of OID bonds to ensure compliance with tax laws and fair-trading practices. Investors and issuers must adhere to specific reporting requirements for tax purposes. The accurate reporting of OID is essential to avoid penalties and ensure compliance with IRS regulations.


Original Issue Discount is a fundamental concept in the fixed-income securities market, offering both challenges and opportunities for investors and issuers. While it presents a potential for higher yields and strategic financial management, it also brings unique tax implications and market risks. Understanding OID is essential for anyone involved in bond investing, corporate finance, or even general financial planning. As the financial landscape evolves, the role and significance of OID in various investment strategies and corporate financing decisions remain paramount.
