What a 1099-OID Form Means and Why You Received It

A 1099-OID reports interest income from bonds and other debt instruments you bought at a discount

A 1099-OID is a tax form that reports original issue discount income. This is interest that accrues on certain bonds and debt securities you own, even if you haven't been paid yet. The IRS requires you to report this income on your tax return in the year it accrues, not in the year you receive the actual cash.

You'll receive a 1099-OID when you own a bond, note, or other debt instrument that was issued at a price below its face value. The difference between what you paid and what you'll eventually receive is the original issue discount — and the IRS treats that difference as taxable interest income spread across the life of the bond.

The most common situations where you'll see a 1099-OID are U.S. Treasury bills, corporate bonds issued at a discount, zero-coupon bonds, and certain savings bonds. If you bought any of these through a brokerage account or held them directly, your issuer or broker will send you this form by January 31st of the following year.

Key Takeaways

• A 1099-OID reports interest income from bonds purchased below their face value, and you must report it even if you haven't received the cash yet.
• The form shows the amount of original issue discount accrued during the tax year, which the IRS treats as taxable interest income.
• You'll receive a 1099-OID from your broker or the bond issuer if you own Treasury bills, zero-coupon bonds, or other discounted debt instruments.
• The income reported on a 1099-OID goes on your tax return as interest income, separate from any actual payments you received during the year.

How original issue discount works

When a bond is issued at a discount, the issuer sells it for less than its face value. For example, a bond with a $1,000 face value might be sold for $900. That $100 difference is the original issue discount. Over the life of the bond, that $100 is treated as interest income that accrues each year, even though you won't receive the full $1,000 until the bond matures.

The IRS doesn't let you wait until maturity to report this income. Instead, you report a portion of the discount each year on your tax return. The 1099-OID tells you exactly how much to report for the current tax year. This applies whether you actually received any cash from the bond or not — you still owe tax on the accrued interest.

This rule exists because the IRS wants to prevent people from deferring income indefinitely. If you could wait until maturity to report the discount, you'd be getting an interest-free loan from the government in the form of deferred taxes. The 1099-OID system ensures the income is taxed as it accrues.

What information appears on the form

A 1099-OID contains several boxes with specific information. Box 1 shows the original issue discount for the current tax year — this is the number you'll report on your tax return. Box 2 shows the federal income tax withheld, if any. Box 3 contains the issue date of the bond or security.

You'll also see the name and address of the issuer or broker who sent the form, your name and Social Security number or tax ID, and the CUSIP number (a unique identifier for the security). Some bonds have additional information in other boxes, such as market discount or acquisition premium, which affect how you calculate your taxable income.

The form comes in two copies: one for you to keep with your tax records, and one that the issuer or broker sends to the IRS. Make sure the information matches your records. If there's an error — wrong amount, wrong Social Security number, or a bond you don't own — contact the issuer or broker right away to request a corrected form.

How to report 1099-OID income on your tax return

The amount shown in Box 1 of your 1099-OID goes on your tax return as interest income. If you file Form 1040, this income is reported on Schedule 1, line 8 (or the appropriate line for interest income on your tax form). You add it to any other interest income you received that year from savings accounts, CDs, or other sources.

If you received a 1099-OID for a bond you sold during the year, the calculation becomes more complex. You may have a capital gain or loss in addition to the original issue discount income. In that case, you'll need to track the adjusted basis of the bond (which includes the discount you've already reported) and compare it to your sale price. A tax professional can help with this calculation.

Keep your 1099-OID with your tax records for at least three years. The IRS matches the forms it receives from issuers and brokers against the income you report, so accuracy matters. If you don't report the income shown on your 1099-OID, the IRS will likely send you a notice.

When you might receive multiple 1099-OIDs

If you own several bonds or debt securities issued at a discount, you may receive more than one 1099-OID. Each issuer or broker sends a separate form for each security. You'll need to add up all the amounts from all your 1099-OIDs and report the total on your tax return.

If you hold bonds through a brokerage account, the broker sends you the 1099-OID. If you hold bonds directly (you own the physical certificate or hold it through a direct registration system), the bond issuer sends you the form. Some people receive 1099-OIDs from both a broker and an issuer for the same bond if there was a transfer during the year — in that case, contact both parties to make sure you're not double-reporting.

The difference between 1099-OID and other interest income forms

A 1099-OID is different from a 1099-INT, which reports regular interest payments. A 1099-INT shows interest you actually received during the year — like interest from a savings account or coupon payments from a bond. A 1099-OID shows interest that accrued but you may not have received yet.

You might receive both forms in the same year. For example, if you own a bond that pays regular coupon interest and was also issued at a discount, the issuer sends you a 1099-INT for the coupon payments and a 1099-OID for the original issue discount. Both amounts are taxable and both go on your tax return as interest income.

Some bonds, like zero-coupon bonds, produce only a 1099-OID because they don't make regular payments — all the return comes from the discount. Other bonds produce only a 1099-INT if they were issued at face value. Understanding which form you receive helps you track your income correctly.

What to do if you lost your 1099-OID or it contains an error

If you don't receive a 1099-OID by February 15th and you know you should have one, contact your broker or the bond issuer. They can resend it or provide a duplicate. Keep a record of when you asked and who you spoke with, in case the IRS questions your return later.

If the form contains an error — wrong amount, wrong Social Security number, or a bond you don't recognize — contact the issuer or broker when ready. They'll issue a corrected form, usually marked as a "corrected" 1099-OID. Once you receive the corrected form, use that number on your tax return instead of the original.

If you can't reach the issuer or broker, or if they refuse to correct an error, you can still file your tax return using the correct information. Keep documentation of your attempts to get the form corrected. If the IRS contacts you, you'll have evidence that you tried to resolve the discrepancy.

Frequently Asked Questions

Do I have to pay tax on 1099-OID income even if I didn't receive any money?

Yes. The IRS requires you to report original issue discount income in the year it accrues, regardless of whether you received a cash payment. This is one of the key differences between 1099-OID income and other types of interest. You may owe tax on income you haven't actually received yet.

What's the difference between original issue discount and market discount?

Original issue discount is the difference between the price when the bond was first issued and its face value. Market discount is the difference between what you paid for a bond on the secondary market and its face value. They're taxed differently, and a 1099-OID reports original issue discount only. Market discount rules are more complex and may require separate reporting.

Can I deduct losses on a discounted bond on my tax return?

If you sell a discounted bond for less than you paid, you may have a capital loss. However, you still have to report the original issue discount income you accrued while you held the bond. The loss and the income are separate items on your tax return and don't cancel each other out automatically.

Why does the IRS make me report income I haven't received yet?

The IRS treats original issue discount as accrued interest to prevent tax deferral. Without this rule, you could buy a discount bond, hold it for years without receiving any cash, and defer all the tax until maturity. The 1099-OID system ensures the income is taxed as it builds up, not all at once at the end.

Do I need to report 1099-OID income if I'm not filing a tax return?

If you have a filing requirement — meaning your income exceeds the threshold for your age and filing status — you must report all income, including 1099-OID income. If you don't have a filing requirement, you generally don't have to file. However, if you had taxes withheld, filing may allow you to get a refund.
