1. Introduction – What is Form 1099-OID?
IRS Form 1099-OID, officially titled “Original Issue Discount,” is a federal information return used to report accrued interest on debt securities sold at a discount. The Internal Revenue Service (IRS) governs this form under Sections 6049 and 1275 of the Internal Revenue Code.
Original Issue Discount (OID) occurs when a debt instrument, such as a bond, note, or certificate of deposit, is initially issued at a price lower than its stated redemption price at maturity. The difference between the discounted purchase price and the full face value represents interest income that accrues over the life of the bond.
2. Purpose of the Form
Form 1099-OID exists to track accrued discount interest that bondholders earn during the tax year. Even if a bond does not pay regular cash interest payments, the IRS considers the annual accretion of OID to be taxable interest income in the year it accrues.
By requiring financial institutions and corporate issuers to file Form 1099-OID, the IRS ensures that taxpayers accurately report this income on their federal income tax returns. It creates a standardized record that matches what the issuer reports with what the investor declares on their tax return.
3. Who Needs to File This Form
Issuers of debt instruments, financial institutions, brokers, and middlemen are required to file Form 1099-OID if they pay or accrue OID on a debt obligation. You must file Form 1099-OID under the following conditions:
- The total Original Issue Discount reportable for a recipient is $10 or more during the calendar year.
- You withheld federal income tax from the recipient under backup withholding rules, regardless of the OID amount.
- You held a debt instrument as a nominee or broker on behalf of the actual owner.
Payers must submit Copy A to the IRS, furnish Copy B to the investor or recipient, and keep Copy C for their internal financial records.
4. Who Is Exempt / Not Required to File
Individual investors and bondholders do not file Form 1099-OID; they receive Copy B from their broker or issuer to assist with tax prep. Additionally, issuers are exempt from filing Form 1099-OID for the following obligations:
- Short-Term Obligations: Debt instruments with a fixed maturity date of one year or less from the date of issuance held by cash-basis taxpayers.
- U.S. Savings Bonds: Interest earned on U.S. Savings Bonds is reported on Form 1099-INT rather than Form 1099-OID.
- Pre-1993 Tax-Exempt Obligations: Tax-exempt obligations issued before May 3, 1993, are exempt from OID reporting rules.
- Exempt Recipients: Payments made to corporations, government agencies, or registered tax-exempt organizations do not require a Form 1099-OID.
5. When to File
Issuers and brokers must adhere to specific IRS filing deadlines each calendar year following the tax year in which the discount interest accrued:
- To the Recipient (Copy B): Due by January 31. If the form is furnished by a broker as part of a composite brokerage statement, the deadline is extended to February 15.
- To the IRS (Paper Copy A): Due by February 28.
- To the IRS (Electronic Copy A): Due by March 31.
Form 1099-OID is an annual return. Issuers must report all OID accrued during the 12 months of the calendar year by the established deadlines.
6. Where and How to File
Form 1099-OID Copy A can be filed with the IRS using paper forms or electronic filing systems. However, any entity filing 10 or more total information returns across all 1099 forms combined must submit electronically.
Electronic filings are processed through the IRS Information Returns Intake System (IRIS) or the Filing Information Returns Electronically (FIRE) portal. Small issuers filing fewer than 10 total returns may submit paper forms along with transmittal Form 1096 to the IRS address listed in the official form instructions.
7. Step-by-Step Instructions to Fill the Form

8. Required Documents/Information Needed Before Filling
Issuers and brokers need complete financial records regarding the debt instrument to prepare Form 1099-OID accurately. Make sure to collect the following items:
- The payee’s verified Taxpayer Identification Number (SSN, ITIN, or EIN) obtained from Form W-9.
- Security documentation, including the CUSIP number, issue date, and stated redemption price at maturity.
- Bond yield schedules showing the constant yield amortization method used to calculate annual OID accrual.

9. Common Mistakes to Avoid
Reporting errors on Form 1099-OID can cause tax discrepancies for investors and lead to IRS notices. Common mistakes include:
- Confusing Form 1099-OID and Form 1099-INT: Reporting OID as regular interest on Form 1099-INT rather than using Form 1099-OID.
- Mishandling Treasury Obligations: Placing OID from U.S. Treasury bills or notes in Box 1 instead of Box 8, which can result in improper state taxation.
- Incorrect Accrual Calculations: Using simple straight-line math instead of the required constant yield method to calculate accrued discount interest.
- Ignoring Acquisition Premiums: Failing to report acquisition premiums in Box 6, which leads to overreporting the investor’s taxable income.
- Missing Broker Extension Deadlines: Forgetting that brokers delivering composite statements have until February 15 to furnish recipient copies.
10. Penalties for Non-Filing or Errors
Payers who fail to file correct Form 1099-OID returns on time are subject to statutory penalties under Sections 6721 and 6722 of the Internal Revenue Code. Penalties are assessed per return and apply separately for late IRS filings and late recipient statements.
Penalty tiers depend on how quickly the error is fixed:
- Corrected within 30 days of the deadline: A minor per-return penalty applies with a reduced annual cap.
- Corrected between 30 days late and August 1: A moderate per-return penalty applies.
- Filed after August 1 or not filed: The full maximum standard per-return penalty applies.
- Intentional Disregard: If the failure to file is due to intentional neglect, significantly higher penalties are charged without a maximum limit.

12. Frequently Asked Questions
What is Original Issue Discount in plain terms?
Original Issue Discount is interest income earned when you buy a bond at a discount below its face value. The difference between the discount price and the maturity face value accrues over time as taxable interest.
Is OID taxable if I didn’t receive cash interest payments this year?
Yes. The IRS treats accrued OID as taxable interest income in the year it accrues, even if you receive no cash payments until the bond matures.
What is the main difference between Form 1099-OID and Form 1099-INT?
Form 1099-INT reports regular coupon interest paid periodically. Form 1099-OID specifically reports the annual accrued discount on debt instruments issued below face value.
Why is Treasury OID listed in Box 8 instead of Box 1?
Treasury OID is reported in Box 8 because interest on U.S. government obligations is exempt from state and local income taxes, whereas Box 1 OID may be subject to state tax.
What is a zero-coupon bond, and why does it generate Form 1099-OID?
A zero-coupon bond pays no periodic cash interest but is sold at a deep discount. It generates Form 1099-OID because the entire gain realized at maturity accrues as annual OID interest.
Do taxpayers need to attach Form 1099-OID to their tax return?
No, you do not attach Form 1099-OID to your paper tax return. You simply use the numbers to complete Schedule B and Form 1040, then keep the form for your records.
13. Conclusion – Key Takeaways
IRS Form 1099-OID ensures that accrued discount interest on bonds and zero-coupon securities is properly reported. Issuers and brokers must report OID of $10 or more, delivering statements to recipients by January 31 (or February 15 for brokerage accounts) and filing with the IRS by February 28 or March 31.
Understanding how OID accrues and utilizing accurate constant yield calculation methods enables issuers to remain compliant while helping taxpayers accurately report their annual investment earnings.
