IRS Pub 1212 – IRS Forms, Instructions, Pubs 2026 – In the complex world of taxation, certain financial instruments can add layers of nuance to your reporting obligations. One such area is Original Issue Discount (OID), which represents a form of interest income that accrues over time on specific debt instruments. If you’re a broker, middleman, or individual investor dealing with bonds, notes, or similar assets, IRS Publication 1212 serves as an essential resource. This guide, officially titled “Guide to Original Issue Discount (OID) Instruments,” helps demystify OID calculations and reporting requirements. Updated as of December 2025, it ensures you’re compliant with the latest IRS rules. Whether you’re figuring OID for tax returns or preparing Forms 1099, this article breaks down the key elements of Pub 1212 to optimize your understanding and tax strategy.
What Is Original Issue Discount (OID)?
Original Issue Discount refers to the difference between a debt instrument’s stated redemption price at maturity and its issue price. Essentially, it’s a type of interest that builds up over the life of the instrument, even if no cash payments are made until maturity. For example, zero-coupon bonds are classic OID instruments because they’re sold at a discount and redeemed at face value, with the difference treated as interest income.
OID must be reported as it accrues annually, regardless of when you receive payments. This accrual-based approach ensures that income is taxed in the year it’s earned, aligning with IRS principles. Pub 1212 emphasizes that OID applies to various debt instruments, including corporate bonds, Treasury STRIPS, and inflation-indexed securities like TIPS. Understanding OID is crucial for investors because failing to report it correctly can lead to penalties or audits.
Key Definitions in IRS Pub 1212
To navigate OID effectively, familiarize yourself with these core terms from the publication:
- OID (Original Issue Discount): The excess of the stated redemption price at maturity over the issue price, allocated over the instrument’s term.
- Accrual Period: The interval (up to one year) used to measure and allocate OID, often six months for many instruments.
- Adjusted Issue Price: The original issue price plus accumulated OID minus any payments (excluding qualified stated interest).
- Acquisition Premium: The amount by which your basis exceeds the adjusted issue price at purchase, which reduces reportable OID.
- Yield to Maturity (YTM): The discount rate that equates the present value of all payments to the issue price, used in OID calculations.
- Qualified Stated Interest: Fixed, unconditional interest payments made at least annually at a single rate.
- Stated Redemption Price at Maturity: The total amount payable at maturity, including principal and interest (minus qualified stated interest).
These definitions form the foundation for OID computations, helping you avoid common pitfalls like confusing OID with market discount (which applies to secondary purchases).
Types of OID Instruments Covered (and Excluded)
Pub 1212 includes detailed OID tables available on the IRS website, categorized into sections for easy reference:
- Section I: Long-term debt instruments, such as corporate bonds issued before and after 1985, taxable obligations, and inflation-indexed instruments.
- Section II: Stripped bonds and coupons, including Treasury STRIPS.
- Section III: Short-term obligations like Treasury bills and agency discounts.
The guide covers publicly offered instruments, contingent payment debt, and inflation-indexed ones (e.g., TIPS issued after January 5, 1997). Special rules apply to stripped bonds, where OID is the excess of redemption value over purchase price, treated as if newly issued on the purchase date.
However, not all instruments fall under these tables. Exclusions include U.S. savings bonds, certificates of deposit (CDs), tax-exempt obligations, mortgage-backed securities, REMICs, CDOs, commercial paper, and foreign obligations not in U.S. dollars. For these, refer to income tax regulations or other IRS publications like Pub 550 for guidance.
How to Figure OID: Step-by-Step Methods?
Calculating OID depends on the instrument’s issuance date and type. Pub 1212 outlines methods like the constant yield approach, which allocates OID ratably over accrual periods.
- For Instruments Issued After 1984: Use the constant yield method with accrual periods of up to one year. Daily OID = (Adjusted issue price × YTM / Number of accrual periods per year) – Qualified stated interest, then divide by days in the period.
- Pre-1985 Instruments: Similar, but with annual accrual periods starting from the issue date.
- Contingent Payment Instruments (Post-Aug. 12, 1996): Apply the noncontingent bond method, projecting payments based on comparable yield and adjusting for actual outcomes.
- Inflation-Indexed Instruments: Use the coupon bond method for par-issued bonds or the discount bond method otherwise. OID includes increases in inflation-adjusted principal, with deflation adjustments offsetting interest.
De minimis rule: If OID is less than 0.25% of the stated redemption price multiplied by years to maturity, treat it as zero. Examples in the publication illustrate these calculations, such as daily OID for partial years or adjustments for acquisition premium.
Adjustments are key—reduce OID for acquisition premium or bond premium, and increase basis by accrued OID for sales or redemptions.
Reporting OID: Guidelines for Brokers and Owners
For Brokers and Middlemen
If you hold OID instruments as nominees, file Form 1099-OID or 1099-INT if OID or interest is $10 or more. Deadlines: Furnish to recipients by January 31 (or February 15 for certain forms) and file with the IRS by February 28 (March 31 electronically). Use OID tables to populate boxes like Box 1 (OID) and Box 8 (OID on U.S. Treasuries). Nominees must file separate forms for actual owners.
Issuers of publicly offered OID instruments must file Form 8281 within 30 days of issuance or SEC registration.
For Owners
Include OID in gross income annually on Schedule B of Form 1040, even without a Form 1099-OID. Report on Line 1 with the payer’s name and amount. Make adjustments (e.g., for premium) via an “OID Adjustment” entry. For sales, report gains/losses on Form 8949 and Schedule D, adjusting basis by included OID. Tax-exempt OID (Box 11 on 1099-OID) isn’t taxable but increases basis.
Inflation-indexed instruments acquired after 2015 are “covered securities,” requiring Form 8949 reporting.
Backup Withholding and Penalties for Non-Compliance
Backup withholding at 24% applies to OID if the payee lacks a valid TIN, provides an incorrect one, or underreports interest/dividends. It occurs at maturity for long-term instruments or upon cash payments for short-term ones. Exceptions include non-U.S. payments with Form W-8 certification.
Penalties include:
- Failure to file/furnish information returns: Varies; see General Instructions for Certain Information Returns.
- Accuracy-related penalty: 20% on underpayments due to negligence or substantial understatement.
Staying compliant avoids these issues—consult Pub 1281 for more on withholding.
