Original Issue Discount (OID): Definition & How It Works

An original issue discount (OID) is a type of debt instrument. Often a bond, OID’s are sold at a lower value than face value when issued, hence the D in OID. On maturity, the face value is paid out to the investor. The difference received is a gain to the investor and is effectively the interest paid by the borrower or issuer.

This is due to the conceptual calculation of the price discount as, effectively, additional income to the bond owner. From the perspective of the IRS, the eventual payout is treated as income. Thus, the OID is effectively a zero-coupon bond treated with annual tax payments based on the expected future payouts.

Tax Consequences

As such, there are tax consequences when handling an original issue discount. These consequences are often seen as the biggest disadvantages of investing in OIDs. The portion of interest earned on maturity is effectively built into the bond’s price calculations.

In other words, the discount is amortized over the life of the bond. Investors are then required to declare this amortized value as taxable income, which results in annual tax due, even though the payment is not received until maturity.

Tax Reporting

IRC Section 6049 states that parties to an original issue discount transaction are required to calculate and report taxes for the bondholders. This means that brokers and other intermediaries are required to fill out form 1099-OID, subject to the value of the transaction surpassing a minimum threshold.

The legal structure of the original issue discount is designed to prevent manipulation of taxes and interest income. Since the income is amortized through the life of the bond, as opposed to calculated on maturity, purchasers of the OID are unable to defer income recognition.

Income Recognition Exemptions

The following debt instruments are exempt from the tax recognition rules outlined above. This list, however, is not exhaustive:

• United States Savings Bonds
• Short-term maturity debt instruments, with terms of less than or equal to one year
• OID municipal bondsMunicipal BondA municipal bond refers to a bond or fixed income security that is issued by a government municipality, township, or state to finance its governmental

In other words, if the de minimis rule is met, the bondholder can disregard OID tax recognition rules.
