Form 1099-INT: Interest Income Boxes Explained
Form 1099-INT, titled Interest Income, shows interest a payer reported for you: taxable interest in box 1, interest on U.S. Savings Bonds and Treasury obligations in box 3, and tax-exempt interest in box 8. The IRS form and instructions linked from its About page were marked Rev. January 2024 when we checked on November 2, 2026, and have the payer file for amounts of at least $10 in boxes 1, 3, or 8 (or at least $600 of interest paid in the course of a trade or business), while Publication 1099 (2026) lists $10 or more ($2,000 or more in some cases) and January 31 for the recipient’s statement.

Who files Form 1099-INT and what it reports
The IRS About Form 1099-INT page lists who gets one:
“File Form 1099-INT for each person:
To whom you paid amounts reportable in boxes 1, 3, and 8 of at least $10.
For whom you withheld and paid any foreign tax on interest.
From whom you withheld (and did not refund) any federal income tax under the backup withholding rules regardless of the amount of the payment.”
The Instructions for Forms 1099-INT and 1099-OID say the same thing with an added amount for interest paid in the course of the payer’s trade or business:
“File Form 1099-INT, Interest Income, for each person: 1. To whom you paid amounts reportable in boxes 1, 3, or 8 of at least $10 (or at least $600 of interest paid in the course of your trade or business described in the instructions for Box 1. Interest Income, later); 2. For whom you withheld and paid any foreign tax on interest; or 3. From whom you withheld (and did not refund) any federal income tax under the backup withholding rules regardless of the amount of the payment.”
“Also, include interest of $600 or more paid in the course of your trade or business not meeting the above criteria, such as interest on delayed death benefits paid by a life insurance company, interest received with damages, interest on a state or federal income tax refund, or interest attributable to certain notional principal contracts with nonperiodic payments.”
The instructions also limit and divide what goes on the form:
“Report only interest payments made in the course of your trade or business including federal, state, and local government agencies and activities deemed nonprofit, or for which you were a nominee/middleman. Report interest that is taxable OID in box 1 or 8 of Form 1099-OID, Original Issue Discount, not on Form 1099-INT. Report interest that is tax-exempt OID in box 11 of Form 1099-OID, not on Form 1099-INT. Report exempt-interest dividends from a mutual fund or other regulated investment company (RIC) on Form 1099-DIV.”
“Do not include in box 1 interest on tax-free covenant bonds or dividends from money market funds (which are reportable on Form 1099-DIV).”
Revision and tax year
The IRS About Form 1099-INT page linked a form and instructions that are both marked Rev. January 2024. Publication 1099 is marked 2026 and carries the Guide to Information Returns used below for the amount and the due dates.
| Document | Revision printed on the document | Catalog number |
|---|---|---|
| Form 1099-INT | Form 1099-INT (Rev. January 2024) | Cat. No. 14410K |
| Instructions for Forms 1099-INT and 1099-OID | Instructions for Forms 1099-INT and 1099-OID (Rev. January 2024) | Cat. No. 27980N |
| Publication 1099 | Publication 1099 (2026) | Catalog Number 46963K |
“Form 1099-INT, Form 1099-OID, and these instructions, contained herein, are continuous use. Both the forms and instructions will be updated as needed.”
The boxes in the table below are the ones printed on that Rev. January 2024 form. This page covers the Rev. January 2024 form and does not compare it with earlier revisions.
The threshold: two IRS documents, two amounts
The Rev. January 2024 instructions put the second amount at $600. Publication 1099 (2026) carries a row for Form 1099-INT with a different amount in its second case, and its What’s New section states the $2,000 threshold for tax years beginning after 2025:
“For tax years beginning after 2025, the minimum threshold amount for reporting certain payments required to be reported on certain information returns and/or perform backup withholding on those payments increased to $2,000 and will be adjusted for inflation beginning in calendar year 2027. Previously, the threshold amount was $600.”
| Document | Amount for Form 1099-INT |
|---|---|
| Instructions for Forms 1099-INT and 1099-OID (Rev. January 2024) | At least $10 in boxes 1, 3, or 8, or at least $600 of interest paid in the course of your trade or business described in the instructions for box 1; foreign tax withheld and paid; and federal income tax withheld (and not refunded) under the backup withholding rules, regardless of the amount of the payment |
| Publication 1099 (2026), Guide to Information Returns | $10 or more ($2,000**** or more in some cases) |
The two documents carry different years and different amounts, and this page does not decide which one applies to a particular payment. The 1099 reporting thresholds page shows the same Form 1099-INT amounts next to the other 1099 forms, and the Form 1099-NEC page covers the $2,000 threshold for nonemployee compensation.

Who does not get a Form 1099-INT
The instructions list payees and interest that need no Form 1099-INT, and the lists are introduced as partial (“including, but not limited to”):
“You are not required to file Form 1099-INT for payments made to certain payees including, but not limited to, a corporation, a tax-exempt organization, any individual retirement arrangement (IRA), Archer medical savings account (MSA), Medicare Advantage MSA, health savings account (HSA), a U.S. agency, a state, the District of Columbia, a U.S. territory, a registered securities or commodities dealer, a nominee or custodian, a broker, or notional principal contract (swap) dealer. For additional exempt recipients, see Regulations section 1.6049-4 for more information. For situations when you are required to file Form 1099-INT for certain recipients that are otherwise generally exempt, but that receive credits from tax credit bonds, see Interest to holders of tax credit bonds under Box 1. Interest Income, later.”
“You are not required to file Form 1099-INT for interest on an obligation issued by an individual, interest on amounts from sources outside the United States paid outside the United States by a non-U.S. payer or non-U.S. middleman, certain portfolio interest, interest on an obligation issued by an international organization and paid by that organization, and payments made to a foreign beneficial owner or foreign payee.”
“Do not report tax-deferred interest, such as interest that is earned but not distributed from an IRA.”
“If you pay U.S. bank deposit interest of at least $10 to certain nonresident alien individuals, report the interest on Form 1042-S, Foreign Person's U.S. Source Income Subject to Withholding.”
Due dates
Publication 1099 (2026) gives the dates in its Guide to Information Returns. The row for Form 1099-INT is shown below with its footnotes:
| Form | Amounts to report | Due date to the IRS | Due date to the recipient |
|---|---|---|---|
| Form 1099-INT | $10 or more ($2,000**** or more in some cases) | February 28* | January 31** |
“* The due date is March 31 if filed electronically.
** The due date is March 15 for reporting by trustees and middlemen of WHFITs.
****The amount is adjusted for inflation every year. Go to IRS.gov/InflationAdjustment for the current year inflation-adjusted amount.”
“If any filing due date in these instructions falls on a Saturday, Sunday, or a legal holiday, you will be considered to have timely filed if you file by the next day that is not a Saturday, Sunday, or a legal holiday. Legal holidays for this purpose are legal holidays in the District of Columbia or a statewide legal holiday where the return is required to be filed.”
The instructions for the form say a statement goes to the recipient, and Publication 1099 says it can go earlier in some cases:
“If you are required to file Form 1099-INT, you must furnish a statement to the recipient. For more information about the requirement to furnish an official form or acceptable substitute statement to recipients, see part M in the current General Instructions for Certain Information Returns.”
“However, you may issue them earlier in some situations, as provided by the regulations. For example, you may furnish Form 1099-INT to the recipient redeeming U.S. Savings Bonds at the time of redemption.”
Interest on savings bonds and Treasury obligations is what box 3 reports. The savings bond calculator, I bond calculator and Treasury auction schedule cover those products, and the high-yield savings calculator and CD rate calculator cover bank interest.
Scope of this page
- This page covers Form 1099-INT as the IRS documents listed under Sources describe it.
- This page does not cover penalty amounts, state filing rules, or Form 1099-OID beyond the sentences quoted above, and it does not explain how any amount is taxed on a return; Copy B and the Instructions for Form 1040 are the IRS’s place for that.
Frequently asked questions
What is Form 1099-INT and who files it?
The IRS About Form 1099-INT page says the form, titled Interest Income, is filed for each person “To whom you paid amounts reportable in boxes 1, 3, and 8 of at least $10”, for whom you withheld and paid any foreign tax on interest, and from whom you withheld (and did not refund) any federal income tax under the backup withholding rules regardless of the amount of the payment. The form and instructions linked on that page were marked Rev. January 2024 when we checked on November 2, 2026.
What is the Form 1099-INT reporting threshold?
The Instructions for Forms 1099-INT and 1099-OID (Rev. January 2024) have the payer file for amounts reportable in boxes 1, 3, or 8 of at least $10, or at least $600 of interest paid in the course of the payer’s trade or business described in the instructions for box 1. Publication 1099 (2026) lists Form 1099-INT as “$10 or more ($2,000**** or more in some cases)”, and a footnote says the amount is adjusted for inflation every year. The two IRS documents carry different years and different amounts, and this page does not decide which one applies to a particular payment.
What is the difference between box 1 and box 3 on Form 1099-INT?
The Instructions for Forms 1099-INT and 1099-OID (Rev. January 2024) say, for box 1, to enter taxable interest not included in box 3, and, for box 3, to enter interest on U.S. Savings Bonds, Treasury bills, Treasury notes, and Treasury bonds and not include it in box 1. Copy B of Form 1099-INT (Rev. January 2024) says of box 3: “This may or may not all be taxable. See Pub. 550. This interest is exempt from state and local income taxes.”
What do boxes 8 and 9 on Form 1099-INT show?
Copy B of Form 1099-INT (Rev. January 2024) says box 8 “Shows tax-exempt interest paid to you during the calendar year by the payer” and box 9 “Shows tax-exempt interest subject to the alternative minimum tax. This amount is included in box 8.”
What do boxes 11, 12 and 13 on Form 1099-INT show?
The Instructions for Forms 1099-INT and 1099-OID (Rev. January 2024) describe each as bond premium amortization allocable to the interest paid: box 11 for a taxable covered security acquired at a premium (other than a U.S. Treasury obligation), box 12 for a U.S. Treasury obligation that is a covered security, and box 13 for a tax-exempt covered security acquired at a premium. Copy B says of box 11: “If an amount is not reported in this box for a taxable covered security acquired at a premium and the payer is reporting premium amortization, the payer has reported a net amount of interest in box 1.” For box 13 it says: “If an amount is not reported in this box for a tax-exempt covered security acquired at a premium, the payer has reported a net amount of interest in box 8 or 9, whichever is applicable.” For box 12 the matching sentence refers to box 3.
When is Form 1099-INT due?
Publication 1099 (2026) lists Form 1099-INT with February 28 for the IRS and January 31 for the recipient. Its footnotes give March 31 if filed electronically, and the footnote attached to the recipient date says “The due date is March 15 for reporting by trustees and middlemen of WHFITs.” It also says that when a filing due date falls on a Saturday, Sunday, or a legal holiday, a filer is considered timely if the filing is made by the next day that is not one of those.
Is interest that is original issue discount reported on Form 1099-INT?
The Instructions for Forms 1099-INT and 1099-OID (Rev. January 2024) say: “Report interest that is taxable OID in box 1 or 8 of Form 1099-OID, Original Issue Discount, not on Form 1099-INT.” They also say that for a specified private activity bond with OID, the tax-exempt OID goes in box 11 on Form 1099-OID and the tax-exempt stated interest in boxes 8 and 9 on Form 1099-INT.
