Banks, brokers, and issuers of debt instruments must rigorously adhere to IRS reporting standards when managing Original Issue Discount (OID) obligations. Form 1099-OID is utilized by paying entities to report the annual accrued discount on long-term debt instruments. This overview details the reporting mechanics for Tax Year 2026 obligations - typically reported to the IRS and furnished to payees in early 2027. It focuses strictly on the responsibilities of the issuing and filing organizations, detailing how to correctly calculate annual daily portions, distinguish between bond and acquisition premiums, and navigate cross-form compliance with Form 1099-INT.
Who Must File Form 1099-OID
According to official IRS instructions, filing Form 1099-OID is mandatory for several types of financial entities and middlemen. You must file if you are an issuer of bonds or other evidence of indebtedness in registered or bearer form issued with OID. This includes financial institutions issuing certificates of deposit (CDs) with terms greater than one year, as well as brokers holding OID obligations as a nominee for the actual owner.
Additionally, trustees and middlemen of widely held fixed investment trusts (WHFITs) or widely held mortgage trusts (WHMTs) must report OID. Real estate mortgage investment conduits (REMICs), financial asset securitization investment trusts (FASITs), and issuers of collateralized debt obligations (CDOs) also have strict reporting mandates under these rules.
Calculating and Reporting Annual OID
A common error among new issuers is attempting to report the entire discount in the year of issuance or maturity. Instead, OID must be reported based on the total daily portions of the discount accrued for the specific part of the year the record holder owned the obligation. OID is defined as the excess of an obligation's stated redemption price at maturity over its issue price.
Issuers must apply the de minimis rule: in the case of a taxable obligation, if the discount is less than one-fourth of one percent (0.25%) of the stated redemption price at maturity multiplied by the number of full years from the date of issue to maturity, the OID is considered to be zero. You must prepare a Form 1099-OID for each holder of record if the total daily portions amount to $10 or more for the year.
Cross-Form Exceptions: Form 1099-INT
Not all discount instruments belong on Form 1099-OID. Issuers must report interest on U.S. Savings Bonds on Form 1099-INT. Furthermore, OID on short-term obligations with a maturity term of one year or less is explicitly excluded from Form 1099-OID and must be routed to Form 1099-INT.
When an obligation features both OID and qualified stated interest, the reporting entity has administrative flexibility. The issuer may report both the OID and the stated interest on Form 1099-OID (using Box 1 for OID and Box 2 for stated interest). Alternatively, the issuer may choose to report the qualified stated interest on Form 1099-INT while strictly reporting the OID portion on Form 1099-OID.
Entity Exemptions and Payee Documentation
Filing Form 1099-OID is generally not required for payments made to exempt recipients. Exempt entities include corporations, tax-exempt organizations, individual retirement arrangements (IRAs), Archer MSAs, Medicare Advantage MSAs, health savings accounts (HSAs), and registered securities or commodities dealers. Government agencies (federal, state, and territorial) are also exempt.
For reportable payees, issuers are permitted to truncate the recipient's Taxpayer Identification Number (TIN) on the furnished payee statements to protect sensitive data. However, truncation is prohibited on the official forms filed with the IRS. Additionally, U.S. payers reporting on U.S. accounts for Chapter 4 purposes must utilize the FATCA filing requirement checkbox on the form.
Fictional Business Numerical Example
Acme Brokerage Corp OID Allocation
To illustrate premium allocations, consider a fictional broker, Acme Brokerage Corp, reporting on a taxable corporate bond that is a covered security for an investor. During the 2026 tax year, the bond accrues $200 in total daily portions of OID and pays $60 in qualified stated interest. The bond also carries $20 in acquisition premium amortization and $5 in bond premium amortization allocable to the stated interest.
Acme Brokerage Corp chooses to report gross amounts. On the investor's Form 1099-OID, Acme enters $200 in Box 1 (Original Issue Discount) and $20 in Box 6 (Acquisition Premium). Because Acme chooses to report the stated interest on the same form, they enter $60 in Box 2 (Other Periodic Interest) and $5 in Box 10 (Bond Premium). Alternatively, Acme could have reported a net OID of $180 in Box 1, leaving Box 6 blank.

Frequently asked questions
What is the reporting threshold for Form 1099-OID?
Issuers must file Form 1099-OID if the total daily portions of OID for a holder are at least $10. However, filing is required regardless of the OID amount if the payer withheld and paid any foreign tax on the OID, or if federal income tax was withheld under backup withholding rules and not refunded.
How do debt issuers determine if the OID is considered zero for reporting?
Under the IRS de minimis rule, if the original issue discount on a taxable obligation is less than one-fourth of 1% (0.25%) of the stated redemption price at maturity, multiplied by the number of full years from the date of issue to maturity, the discount is considered to be zero and does not require OID reporting.
Should short-term obligations be reported on Form 1099-OID?
No. Obligations with a fixed maturity term of one year or less from the date of issue are excluded from Form 1099-OID. Any OID generated from these short-term obligations must be reported on Form 1099-INT instead.
Can issuers truncate Taxpayer Identification Numbers (TINs)?
Issuers and brokers may truncate the recipient's TIN (such as an SSN or EIN) on the payee statements furnished to the account holder. However, the payer's TIN cannot be truncated on any document, and the recipient's TIN must be fully visible on the forms filed directly with the IRS.
When must the FATCA filing requirement box be checked?
The FATCA box must be checked if a U.S. payer is reporting amounts in Boxes 1, 2, and 8 to satisfy Chapter 4 reporting requirements for a U.S. account. It is also required if a Foreign Financial Institution (FFI) is reporting payments to a U.S. account pursuant to specific IRS election regulations.
