Form 1099-OID: Original Issue Discount for 2023

What the Form Is For

Form 1099-OID (Original Issue Discount) is a tax document that reports a specific type of interest income you may have earned from certain bonds, notes, or other debt instruments purchased at a discount. Think of it this way: if you buy a bond for $900 that will pay you $1,000 when it matures, that $100 difference is considered Original Issue Discount—and it's taxable as interest income, even though you haven't received the cash yet.

OID represents the difference between what you paid for a debt instrument and what you'll receive when it matures. The IRS treats this discount as interest that accrues over the life of the bond, similar to how interest accumulates in a savings account. Common investments that generate OID include zero-coupon bonds (bonds that pay no annual interest), certain corporate bonds, some certificates of deposit (CDs) with terms longer than one year, and stripped bonds or coupons from U.S. Treasury securities.

You'll receive Form 1099-OID from the financial institution, broker, or issuer who holds your debt instrument if the OID includible in your gross income is at least $10 for the year. According to the IRS, you must also receive this form if any foreign tax was withheld on your OID, or if federal income tax was withheld under backup withholding rules—even if the OID amount is less than $10.

The key thing to understand is that you may owe taxes on OID even if you haven't received any cash payments during the year. This is called "phantom income," and it's one of the most confusing aspects of OID reporting for taxpayers.

When You’d Use Form 1099-OID

Late/Amended Filings

Form 1099-OID is typically issued by January 31 for the previous tax year (or by February 15 if it's part of a consolidated statement). As a recipient, you use the information from this form when preparing your annual tax return, which is typically due on April 15.

If you receive a Form 1099-OID after you've already filed your tax return, you may need to file an amended return using Form 1040-X. The IRS generally prefers corrections to be made within three years of the original filing date, as this is the window to amend your personal tax return and potentially collect a refund. While there's no hard deadline for filing corrections to 1099 forms, waiting too long could result in penalties if the IRS discovers the discrepancy first.

Late filing scenarios requiring an amended return include: receiving a corrected 1099-OID showing a different amount than originally reported, discovering you failed to report OID income that appeared on a form you overlooked, or finding calculation errors in how you reported the OID on your original return. If you discover any of these situations, don't panic—the IRS understands that mistakes happen.

If your financial institution made an error on the original Form 1099-OID they sent you, they should issue a corrected form clearly marked "CORRECTED" at the top. When you receive a corrected form, compare it carefully to what you originally reported. If the correction changes your tax liability, you'll need to file Form 1040-X to amend your return.

It's worth noting that payers (financial institutions and brokers) face their own deadlines. They must file Forms 1099-OID with the IRS by February 28 if filing on paper, or March 31 if filing electronically, accompanied by Form 1096. Missing these deadlines can result in penalties for the payer, but as a taxpayer, you're responsible for reporting the income correctly regardless of whether you received the form on time.

Key Rules or Details for 2023

For the 2023 tax year, several important rules governed Form 1099-OID reporting. First, the $10 threshold remained in effect—you should receive a 1099-OID if your OID income from any single source was $10 or more during the year. However, you're still required to report OID income on your tax return even if it's below this threshold and you don't receive a form.

The de minimis rule provides relief for very small discounts. If the OID on a debt instrument is less than one-quarter of 1% (0.0025) of the stated redemption price at maturity, multiplied by the number of full years to maturity, the OID is considered zero for tax purposes. This means small discounts don't trigger OID reporting requirements.

For 2023, the accrual method remained the standard for calculating OID. This means you must include OID in your income as it accrues over the term of the debt instrument, using either the constant yield method or information provided on Form 1099-OID. The constant yield method spreads the discount proportionally over the life of the bond, with slightly increasing amounts each year to reflect compound interest.

Important distinctions apply to different types of debt instruments. Short-term obligations (those with terms of one year or less) have their discount reported on Form 1099-INT, not Form 1099-OID. U.S. Savings Bonds don't generate Form 1099-OID; their interest is reported differently. Tax-exempt OID from municipal bonds appears in Box 11 of Form 1099-OID and generally doesn't create federal tax liability, though you still need to report it.

The 2023 rules also addressed special situations like acquisition premium (when you buy a bond at a price between its discounted issue price and par value) and bond premium (when you pay more than the total payable amount). These situations can reduce or eliminate your reportable OID income. If you bought a bond with OID in the secondary market rather than at original issue, your calculation becomes more complex, potentially involving adjustments for acquisition premium or market discount.

Step-by-Step (High Level)

Box-by-Box Guide

Box 1 – Original Issue Discount

This is the taxable OID that accrued during the portion of the year you owned the debt instrument. This amount goes on your tax return as interest income, even if you received no cash payment. Report this on Schedule B (Form 1040) if your total interest income exceeds $1,500, or directly on Form 1040, line 2b if it's less.

Box 2 – Other Periodic Interest

This shows qualified stated interest that was actually paid or credited to you during the year. This is real cash interest, as opposed to the accrued OID in Box 1. Add this to your other interest income when filing.

Box 3 – Early Withdrawal Penalty

If you cashed in a CD or similar instrument early and paid a penalty, that amount appears here. Good news: you can deduct this penalty from your gross income on Schedule 1 (Form 1040), line 18, reducing your taxable income.

Box 4 – Federal Income Tax Withheld

Shows any backup withholding (typically 24% for 2023) that was deducted from your OID. This happens if you failed to provide your correct Social Security number or ignored IRS backup withholding notices. Report this on your Form 1040 as a tax payment credit.

Boxes 5-6 – Market Discount and Acquisition Premium

These boxes help adjust your OID if you bought the bond on the secondary market. These adjustments can be complex; most taxpayers benefit from consulting Publication 1212 or a tax professional for these scenarios.

Box 7 – Description

Contains the CUSIP number (a unique identifier) or description of the debt instrument. Keep this for your records.

Box 8 – Original Issue Discount on U.S. Treasury Obligations

If your OID came from Treasury securities, it appears here instead of Box 1. Treasury OID is exempt from state and local taxes in most jurisdictions, though it remains federally taxable.

Boxes 11-14

Used for tax-exempt OID and any state tax withholding information.

How to Use the Information on Your Return

To complete your tax return, add the amounts from Box 1 (or Box 8 for Treasury obligations) plus Box 2 to your other interest income. Report the total on Schedule B, Part I if your interest exceeds $1,500, or directly on Form 1040 if below that threshold. Don't forget to claim any penalty (Box 3) as a deduction and any withholding (Box 4) as a credit.

Common Mistakes and How to Avoid Them

Common Mistake 1: Forgetting to Report OID Altogether

The most frequent error taxpayers make with Form 1099-OID is simply forgetting to report it altogether. Because you may not have received any cash during the year, it's easy to overlook this form. Set up a filing system where you keep all 1099 forms together, and carefully check each one when preparing your return. Missing OID income can trigger an IRS notice and potential penalties.

Common Mistake 2: Confusing Box 1 and Box 2 Amounts

Another common mistake involves incorrect box amounts, particularly confusion between Box 1 and Box 2. Remember: Box 1 is accrued interest you haven't received yet (phantom income), while Box 2 is actual interest paid to you. Both are taxable, but they represent different things. When reporting, add them together as interest income—don't accidentally report Box 1 twice or omit Box 2.

Common Mistake 3: Missing the Early Withdrawal Penalty Deduction

Many taxpayers fail to claim the early withdrawal penalty deduction shown in Box 3. If you broke a CD early and paid a penalty, that amount reduces your taxable income—but only if you remember to claim it on Schedule 1. This is money back in your pocket, so don't leave it on the table.

Common Mistake 4: Box 10 Software Error on Bond Premium

The Box 10 error is particularly common with tax software. Box 10 shows bond premium on taxable bonds, which reduces the amount of interest you report. However, software sometimes flags errors if Box 10 exceeds Box 2. This typically requires manual review and adjustment. If you're filing electronically and encounter this error, verify the amounts on your actual form and consult the software's help resources or a tax professional.

Common Mistake 5: Mishandling Tax-Exempt OID (Box 11)

Taxpayers also frequently mishandle tax-exempt OID from municipal bonds (Box 11). While this OID doesn't create federal tax liability, you must still report it on your tax return on specific lines designated for tax-exempt interest. Failing to report tax-exempt income, even though it's not taxable, can trigger IRS matching problems.

Common Mistake 6: Acquisition Premium and Market Discount Adjustments

Acquisition premium and market discount adjustments trip up many filers. If you bought a bond on the secondary market, you may need to adjust the OID reported in Box 1. The form doesn't automatically account for when or at what price you purchased the bond. Publication 1212 provides detailed guidance, but these situations often warrant professional help.

Common Mistake 7: Mixing Up 1099-INT and 1099-OID

Finally, mixing up 1099-INT and 1099-OID is surprisingly common. Interest on U.S. Savings Bonds and short-term obligations appears on Form 1099-INT, not 1099-OID. Make sure you're looking at the correct form when reporting each type of interest income.

What Happens After You File

Once you've filed your tax return including Form 1099-OID information, the IRS computers automatically match the amounts you reported against the forms filed by your brokers and financial institutions. This matching process typically occurs several months after the filing deadline.

If everything matches, you'll hear nothing—silence is golden with the IRS. Your return is processed, any refund due is sent (typically within 21 days for e-filed returns), and your tax obligation for the year is settled. Keep copies of your 1099-OID forms and tax return for at least three years in case the IRS has questions later.

If there's a discrepancy between what you reported and what appears on the 1099-OID forms submitted to the IRS, you'll receive a notice—typically a CP2000 or similar. These notices aren't bills or audits; they're proposed adjustments. The notice will explain the discrepancy and calculate the additional tax, interest, and potential penalties if the IRS is correct.

When you receive such a notice, don't panic. You have the right to respond, typically within 30 days. If the IRS is correct and you simply missed reporting the OID income, you can agree to the adjustment and pay the amount due (often with a payment plan if needed). If you believe the IRS is wrong—perhaps because you made an adjustment for acquisition premium that didn't appear on the 1099-OID but was legitimate—you can respond with documentation supporting your position.

Basis adjustment is an ongoing consequence of reporting OID. Each year you include OID in your income, you increase your basis (cost) in the debt instrument by that amount. This prevents double taxation when you eventually sell or redeem the bond. For example, if you bought a zero-coupon bond for $900 and reported $20 of OID income, your new basis is $920. When the bond matures for $1,000, you only pay tax on $80 of gain ($1,000 - $920), not $100, because you already paid tax on the $20 OID. Keep careful records of OID reported each year to calculate your correct basis.

If you need to make corrections after filing, you have three years from the original filing deadline to amend your return and claim a refund. The clock typically starts on April 15 of the year after the tax year. File Form 1040-X with corrected Schedule B and an explanation of the changes.

FAQs

1. Do I owe taxes on OID even if I didn't receive any cash?

Yes, this is the counterintuitive reality of OID taxation. The IRS considers OID to be interest that accrues over time, similar to interest in a savings account, even if you're not receiving annual payments. You must report and pay tax on the OID shown in Box 1 of Form 1099-OID, regardless of whether you received actual cash. This is often called "phantom income." However, the silver lining is that reporting this OID each year increases your basis in the bond, reducing your taxable gain when you eventually sell or redeem it.

2. What if I didn't receive a Form 1099-OID but I know I own bonds that were issued at a discount?

You're still required to report the OID income even without receiving the form. Financial institutions only send Form 1099-OID if the OID is $10 or more, but any amount is technically taxable. You can calculate the OID yourself using IRS Publication 1212, which contains tables of publicly offered debt instruments with OID amounts listed. Alternatively, contact your broker or financial institution to request the information. For bonds purchased on the secondary market, calculations become more complex and may warrant professional assistance.

3. How do I report OID from U.S. Treasury securities differently?

OID from U.S. Treasury obligations appears in Box 8 of Form 1099-OID rather than Box 1. While this OID is subject to federal income tax (report it on your federal return just like other OID), it's generally exempt from state and local income taxes. When filing your state return, make sure to properly exclude this amount if your state honors the federal exemption for Treasury interest. Keep your Form 1099-OID handy when preparing state returns to document the source of this tax-exempt interest.

4. I sold my OID bond before maturity. How does this affect my taxes?

When you sell an OID bond before maturity, you need to report both the accumulated OID income and any capital gain or loss from the sale. First, report the OID that accrued while you owned the bond (shown on Form 1099-OID) as interest income. Second, calculate your gain or loss by comparing your sale proceeds to your adjusted basis. Your adjusted basis is your original purchase price plus all the OID you've reported as income over the years minus any payments received. Report the capital gain or loss on Schedule D and Form 8949. This ensures you're not double-taxed on the OID portion.

5. Can I avoid OID taxation by holding bonds in a retirement account?

Yes, this is one strategy to defer OID taxation. When you hold OID bonds inside a tax-deferred retirement account like a traditional IRA or 401(k), you don't have to report the annual OID income on your current tax return. The income accumulates tax-free within the account, and you only pay taxes when you take distributions from the retirement account (typically in retirement, potentially at a lower tax rate). However, Roth IRAs offer even better treatment—the OID accrues tax-free and qualified distributions in retirement are completely tax-free.

6. What should I do if I receive a corrected Form 1099-OID after filing my return?

First, compare the corrected form to what you originally reported. If the correction doesn't change your tax liability significantly (the IRS typically allows small variances), you may not need to do anything. However, if the correction materially affects your return, you should file Form 1040-X (Amended U.S. Individual Income Tax Return) to correct your filing. Include an explanation of the changes and attach the corrected Form 1099-OID. You generally have three years from the original filing deadline to amend and claim any refund due. If the correction means you owe more tax, file the amendment promptly to minimize interest charges.

7. How does bond premium affect my OID reporting?

If you bought a bond at a premium (paying more than the total amount you'll receive at maturity), this generally eliminates OID reporting going forward. Box 10 of Form 1099-OID shows bond premium amortization for taxable bonds, which reduces your reportable interest income. Some brokers report "net" interest in Box 1 or Box 2 (already reduced by the premium amortization) and leave Box 10 blank; others report gross amounts in both places. Check your brokerage statement or contact your broker to understand their reporting method. If you paid a premium, you may be able to elect to amortize it, which can provide annual tax benefits by reducing your taxable interest income each year.
