IRS Form 1099-OID – In the world of taxation, certain investment income types require specific reporting to ensure compliance with IRS regulations. One such form is IRS Form 1099-OID, which stands for Original Issue Discount. This form is crucial for reporting interest income from debt instruments issued at a discount. Whether you’re an investor receiving OID income or a payer responsible for issuing the form, understanding its purpose, requirements, and updates for the 2025 tax year is essential. In this comprehensive guide, we’ll break down everything you need to know about Form 1099-OID, including how to interpret it and key deadlines.

What Is Original Issue Discount (OID)?
Original Issue Discount refers to the difference between the stated redemption price at maturity of a debt instrument (like bonds, notes, or certificates of deposit) and its issue price, provided that difference is at least a de minimis amount. This discount is treated as interest income and must be reported over the life of the instrument, even if no actual cash payments are made until maturity.
For example, if you purchase a bond for $900 that matures at $1,000, the $100 difference is OID, which accrues as taxable interest income annually. This applies to taxable obligations, U.S. Treasury obligations, and even tax-exempt bonds in certain cases. OID is reported as interest under section 6049 of the Internal Revenue Code.
Who Must File Form 1099-OID?
Form 1099-OID must be filed by payers (such as brokers, banks, or issuers) if:
- The OID includible in the recipient’s gross income is at least $10 for the tax year.
- Any foreign tax was withheld and paid on OID.
- Any federal income tax was withheld under backup withholding rules, even if the OID is less than $10.
This includes reporting for market discount under an election per section 1278(b), OID on U.S. Treasury obligations, and tax-exempt OID. Nominees or middlemen who receive a 1099-OID on behalf of another must file a nominee return. Trustees of widely held fixed investment trusts (WHFITs) must also report OID items.
Recipients include individuals, corporations, or other entities who hold these discounted debt instruments. If you’re a recipient and receive Form 1099-OID showing taxable amounts, you must report these on your tax return, such as Form 1040.
