Built on the current IRS Form 1099-INT and its box-by-box instructions
Make sense of your 1099-INT
Form 1099-INT reports interest you earned: from a bank account or CD, from a corporate bond, from U.S. Treasury and savings bonds, and from tax-exempt municipal bonds. What trips people up isn't the form, it's that the boxes are taxed differently, since box 1 interest is taxable everywhere, box 3 Treasury interest is exempt from state tax, and box 8 municipal interest isn't taxed federally at all. This page walks every box and how it's taxed, and if you need to produce or replace a 1099-INT, the generator drops each amount in the right box and builds a clean copy to preview free.

How it works
Three steps from an interest payment to a finished 1099-INT
No cross-checking which box takes bank interest versus Treasury interest versus municipal interest. Enter the amounts and the generator lays out a completed 1099-INT, drops each one in the box that matches how it's taxed, carries any withholding through, and builds both the recipient copy and the IRS copy.
Add the payer's details, the recipient's name and taxpayer ID, and the amount for each kind of interest paid during the year.

Why this generator
Built around the parts of a 1099-INT people actually get wrong
The form is short. What trips people up is the reading: which box a type of interest goes in, and that box 1, box 3, and box 8 are taxed differently, one everywhere, one exempt from state tax, one exempt from federal tax. Those are the parts this page and tool handle.
The right box for the interest
Bank interest, Treasury interest, and municipal interest each have their own box. The tool drops each amount in the one that fits, so the right tax rule follows it onto the return.
Federal or state, spelled out
Box 3 Treasury interest is exempt from state tax, and box 8 municipal interest isn't taxed federally. This page draws those lines clearly so you don't pay tax you don't owe.
The reporting threshold, clear
A payer files at $10, but you report all your interest, even a few dollars and even with no form. This page keeps that difference straight so nothing slips off the return.
Withholding carried through
Federal tax withheld in box 4, usually backup withholding when a TIN is missing or flagged, is carried through so the recipient can claim it as a credit.
Recipient and IRS copies
The generator builds Copy B for the recipient and Copy A for the IRS from one entry, so both obligations are covered in a single pass.

Interactive guide
Every box on Form 1099-INT, explained
The form is a column of numbered boxes, one for each kind of interest and adjustment. Tap or click a box to see what goes in it, how it's taxed, and the mistake to avoid.
1099-INTInterest Income
TopPayer & recipient details
Above the numbered boxes sits the identifying information: the payer, meaning the bank, broker, or other institution that paid the interest, and the recipient's name, address, and taxpayer ID number, plus an optional account number and a FATCA checkbox. The form may show only the last four digits of your TIN for your protection.
Watch forYou'll often get a 1099-INT inside a broker's composite statement, bundled with a 1099-B and 1099-DIV. Each payer sends its own form, and interest under $10 may not generate one at all, yet it's still reportable.
Box 1Interest income
Box 1 shows ordinary taxable interest paid to you: interest from a savings or checking account, a CD, a money market account, or a corporate bond. It's taxable on both your federal and state returns at ordinary rates. Report it on the taxable interest line of Form 1040.
Watch forCombine box 1 from every 1099-INT you get. If your total taxable interest tops $1,500, you also file Schedule B. Any market discount in box 10 gets added to this box 1 interest.
Box 2Early withdrawal penalty
Box 2 shows a penalty the payer charged for taking money out of a time deposit, like a CD, before it matured. It reduces what you actually kept, so the tax code lets you back it out.
Watch forThis isn't tax withheld, and people confuse it with box 4. It's a deduction: claim the box 2 amount as an adjustment to income on Schedule 1, which lowers your taxable income even if you take the standard deduction.
Box 3U.S. savings bond & Treasury interest
Box 3 shows interest on U.S. Treasury bills, notes, and bonds, and on U.S. savings bonds. It's taxable on your federal return, but it's exempt from state and local income tax, which is why it sits apart from box 1.
Watch forKeep box 3 separate so your state return leaves it out; folding it into box 1 makes you overpay state tax. Series EE and I savings bond interest used for qualified education can be excluded on Form 8815.
Box 4Federal income tax withheld
Box 4 shows federal income tax the payer held back, almost always backup withholding at 24%. That happens when your taxpayer ID is missing, wrong, or flagged by the IRS.
Watch forClaim this amount as a payment on your Form 1040, where it counts against what you owe. Any figure in box 4 also means the payer files the form no matter how small the interest was.
Box 5Investment expenses
Box 5 shows your share of investment expenses from a single-class real estate mortgage investment conduit, or REMIC. The amount is already included in the box 1 interest and is shown here for information.
Watch forSince the 2017 tax law, these miscellaneous investment expenses generally aren't deductible on your return, so for most people box 5 is informational only rather than a write-off.
6–7Foreign tax paid & country
Box 6 shows foreign income tax paid on the interest, in U.S. dollars, and box 7 names the foreign country or U.S. territory it was paid to. They come up with foreign bonds or funds.
Watch forYou can usually claim the box 6 amount as a foreign tax credit on Form 1116, or in some cases a smaller amount without that form, or take it as an itemized deduction instead. Box 7 just identifies where the tax went.
Box 8Tax-exempt interest
Box 8 shows tax-exempt interest, usually from municipal bonds issued by a state, city, territory, or tribal government. It isn't taxed on your federal return, but you still report it on the tax-exempt interest line of Form 1040.
Watch forTax-exempt federally doesn't mean tax-exempt everywhere. Your state may tax municipal interest from other states, and box 8 interest counts when figuring how much of your Social Security is taxable. Reduce it by any box 13 bond premium.
Box 9Specified private activity bond interest
Box 9 shows the part of box 8 that comes from specified private activity bonds. It's already included in the box 8 total, but it's broken out because it can be subject to the alternative minimum tax.
Watch forThis only matters if you're subject to the AMT, where box 9 interest is added back on Form 6251. If you aren't, box 9 has no separate effect beyond what's already in box 8.
10–13Market discount & bond premium
These four boxes fine-tune bond interest for covered securities. Box 10 is market discount, which adds to your box 1 interest. Boxes 11, 12, and 13 are bond premium, which reduces interest: box 11 against box 1, box 12 against box 3 Treasury interest, and box 13 against box 8 tax-exempt interest.
Watch forBrokers often net these against the interest already shown, so check whether box 1, box 3, or box 8 is the gross or the net figure before you adjust it again on your return.
14–17CUSIP & state tax
Box 14 shows the CUSIP number for a tax-exempt or tax credit bond, for identification. Boxes 15 through 17 hold the state, the payer's state identification number, and any state income tax withheld.
Watch forState tax withheld in box 17 is claimed on your state return, not your federal one. Box 14 is informational only and doesn't go anywhere on your return.
The basics
What is Form 1099-INT?
Quick answer
Form 1099-INT, Interest Income, is an information return a payer files to report interest it paid you during the year: interest from a bank or credit union account, a CD, a corporate bond, U.S. Treasury and savings bonds, and tax-exempt municipal bonds. You get a copy so you can report the interest on your return, and the IRS gets a matching copy.
It's a matching document as much as a receipt. The IRS uses the copy it receives to line up the interest a payer reported against what shows up on your return, so an amount you leave off can trigger a CP2000 underreported-income notice months later. And because payers report even small amounts, it's worth checking that every 1099-INT you got made it onto the return.
The part that trips people up is that the boxes aren't taxed the same way. Box 1 ordinary interest is taxable everywhere. Box 3 Treasury and savings bond interest is taxable federally but exempt from state tax. Box 8 municipal interest isn't taxed on your federal return at all. The form's job is to sort interest into those buckets; your return is where each bucket gets its own rule.
Like other 1099s, you don't attach a 1099-INT to your return. You take the amounts from the boxes and put them on Form 1040: taxable interest on line 2b, tax-exempt interest on line 2a. If your total taxable interest tops $1,500, you also file Schedule B. Keep the form with your records in case the IRS asks.
The key idea
A 1099-INT reports interest you earned. Whether you owe tax depends on the box: box 1 is taxable federal and state, box 3 is federal-only, and box 8 is neither on your federal return. Read the boxes, apply the rule for each, and the form is done.
Is it taxable?
Which parts of a 1099-INT are taxable, and where
The most common 1099-INT question is whether you owe tax on the interest. It depends on the box, and on whether you mean federal or state tax. Here's how the common amounts break down.

The box 3 rule is the one people miss: interest on Treasury bills, notes, bonds, and U.S. savings bonds is taxable on your federal return but exempt from state and local income tax. That's the reason it sits in its own box instead of box 1. If your software or preparer folds box 3 into ordinary interest, your state return can end up taxing money the state isn't allowed to tax.
The box 8 rule runs the other way. Municipal bond interest isn't taxed federally, but you still report it, and it isn't always free at the state level: many states tax muni interest from other states while exempting their own. Tax-exempt interest also feeds into how much of your Social Security is taxable, so it isn't purely cosmetic. And remember the reporting rule that sits behind all of this: you report every dollar of taxable interest whether or not a form arrives, with Schedule B once the total tops $1,500.
Thresholds
How much triggers a 1099-INT
The number that matters most is the payer's filing threshold, which for common interest is low. Here's where each trigger stands for 2026, and the reminder that the payer's floor isn't your reporting floor.
Reporting trigger
What it covers
Threshold, 2026
Box 1
Interest income (bank, CD, corporate bond)
$10 or more
Box 3
Treasury & U.S. savings bond interest
$10 or more
Box 8
Tax-exempt (municipal) interest
$10 or more
Business interest
Other interest paid in a trade or business
$2,000
Box 4
Federal tax withheld (backup withholding)
Any amount
Swipe the table sideways for the full text →
Most interest, the kind from a bank account, CD, Treasury, or municipal bond, is reported at $10, the floor it's had for years. What moved is the threshold for interest paid in the ordinary course of a trade or business, like interest on a legal settlement, on a delayed death benefit, or that a business pays on a late payment: the One Big Beautiful Bill Act, enacted in July 2025, raised it from $600 to $2,000 for payments made in 2026 and later. Box 4 has no floor at all, so any backup withholding means the form is filed regardless of the interest amount.
Here's the part recipients get wrong: the $10 is the payer's floor, not yours. You have to report all of your taxable interest, even a couple of dollars that never generated a form. If a payer didn't send a 1099-INT because the interest was under $10, pull the total from your year-end statement and report it anyway. The income counts either way.
Try it
Estimate the federal tax on your 1099-INT
Enter your interest by box and the federal tax already withheld, then pick your marginal rate. The tool shows the federally taxable interest and a rough estimate of what's left to pay or come back. It's a planning figure, not a return.
Box 1 and box 3 are taxed federally; the box 2 penalty is subtracted as a deduction. Box 3 is exempt on your state return, and box 8 is left out entirely. A rough estimate using one flat rate, not a full return. This isn't tax advice.
If box 4 covers more than the estimated tax, part of it may come back as a refund. Report the amounts on your return, and if you need to produce the form, fill out your 1099-INT here.
Type an amount into box 8 and the federal total doesn't move, which is the whole point: tax-exempt interest isn't federally taxed, though it still gets reported and can affect your state return and how much of your Social Security is taxable. Box 3 sits in the federal total here, but on a state return you'd take it back out, since Treasury and savings bond interest is exempt from state tax.
The calendar
When Form 1099-INT is due
A 1099-INT has two deadlines, not one: the copy furnished to the recipient, and the copy filed with the IRS. Here's the calendar, plus the broker exception that shifts one date.
Recipient copy · generally January 31
The payer furnishes Copy B to the recipient by January 31. For 2026 forms that date falls on a Sunday, so it moves to February 1, 2027. One wrinkle: when a 1099-INT is part of a broker's composite or consolidated statement, that statement can be furnished by February 15, which is why brokerage tax packets often arrive in mid-February.
IRS copy · end of February on paper, March 31 if e-filed
The payer files Copy A with the IRS by the end of February on paper, or by March 31 if e-filing. For 2026 forms the paper deadline moves to March 1, 2027, since the usual date lands on a weekend, and the e-file deadline is March 31, 2027. When a due date falls on a weekend or holiday, it moves to the next business day.
Anyone filing 10 or more information returns of any type combined has to e-file, a threshold that counts every 1099, W-2, and similar form together, not each kind on its own. The IRS is retiring the older FIRE system at the end of 2026, so filings for 2026 and forward go through IRIS, the Information Returns Intake System, which also lets you e-file 1099-series forms at no cost.
If you're a recipient and a form is late or never comes, don't wait on it. Your year-end account statement shows the interest, so total it and report it, since the IRS expects the income whether or not the paper reaches your mailbox. If a 1099-INT looks wrong, ask the payer for a corrected form before you file.
For 2026 and beyond
New for 2026
The 1099-INT form itself is stable, so the changes for 2026 are about a threshold and the filing system, not the boxes. Here's what to keep in mind.
$600 becomes $2,000
A higher business-interest floor. The threshold for interest paid in the ordinary course of a trade or business rose from $600 to $2,000 for 2026 payments, under the One Big Beautiful Bill Act. It's the same change that lifted the floor on 1099-NEC and 1099-MISC.
The $10 rule holds
Common interest is unchanged. Interest from a bank account, CD, Treasury, or municipal bond is still reported at $10 or more in box 1, box 3, or box 8. The boxes and their numbering didn't change for 2026.
IRIS replaces FIRE
A new e-file portal. The IRS is retiring the older FIRE system at the end of 2026, so filings for 2026 and forward go through IRIS. Anyone filing 10 or more information returns of any type combined has to e-file.
Match the revision
Use the year's form. The 1099-INT is a continuous-use form, updated as needed rather than reissued every year. The current revision covers 2026 and forward, so make sure the form matches the tax year you're reporting.
Worth remembering: the $2,000 floor applies to that narrow slice of business-course interest, like interest on a legal settlement or a delayed death benefit, not to everyday bank, CD, or bond interest, which stays at $10. When an amount is close to a line, filing anyway is common, since there's no penalty for filing a form you didn't strictly have to.
Avoid these
The mistakes that trip up a 1099-INT
Most 1099-INT problems come down to reading the boxes right, not math. Clear this short list and the interest goes on your return clean.
Leaving small interest off
The $10 figure is the payer's floor, not yours. All taxable interest is reportable, even a few dollars with no form. Skipping it is the fastest way to a CP2000 notice with tax and interest added later.
Taxing box 3 on your state return
Treasury and savings bond interest in box 3 is exempt from state and local tax. Folding it into ordinary interest means your state return taxes money the state isn't allowed to tax.
Thinking box 8 is invisible
Tax-exempt interest still gets reported. It can be taxable by your state if the bonds are from elsewhere, and it counts toward how much of your Social Security is taxed, so it isn't a free pass to ignore.
Missing the box 4 credit
Backup withholding in box 4 is a payment you already made. Claim it on the withholding line of your 1040; leaving it off quietly overpays what you owe.
Skipping Schedule B over $1,500
Once your total taxable interest tops $1,500, you file Schedule B along with the return. Putting the total straight on the 1040 without it can hold the return up.
Forgetting the box 2 deduction
An early withdrawal penalty in box 2 is a deduction, not a loss you just eat. Claim it as an adjustment on Schedule 1, which lowers your taxable income even without itemizing.
One more
Don't overlook the ripple effects. Tax-exempt interest counts when figuring how much of your Social Security is taxable, and Treasury interest that's exempt at the state level still needs backing out on your state return. The box 4 withholding is federal only, so state withholding, when it applies, sits in the state boxes.
Filing it
How a Form 1099-INT is filed
Recipients don't file a 1099-INT; the bank, broker, or other payer does. If you received one, your job is to report the interest on your return. This section is for the payer side and for producing or replacing a copy.
1
E-file through IRIS
You can e-file 1099-series forms at no cost through the IRS IRIS portal, or through commercial software. E-filing is required once you're at 10 or more information returns of any type combined, and it carries the later IRS deadline of March 31.
Required at 10+ returns
2
Paper file by mail
Filing fewer than 10 returns, you can mail paper Copy A to the IRS with a Form 1096 transmittal by the end of February. Use the scannable official Copy A, not a printout of the red form, and keep your records.
Under 10 returns
3
Software or a preparer
Banks, credit unions, and brokers issuing many forms, or handling state copies, can batch the filing, manage state requirements, and track the deadlines through commercial software or a preparer.
When it's at scale
Where this tool fits
This generator helps you fill out and produce a completed Form 1099-INT, both the recipient copy and the IRS copy, that you can review, then e-file or print and mail yourself. It doesn't transmit anything to the IRS, it isn't a substitute for tax software or a tax professional, and it isn't tax advice. You're responsible for the accuracy of the figures and for meeting both deadlines.
Whichever route a payer takes, Copy B has to reach the recipient by their deadline, by mail or, with consent, electronically. If a mistake turns up after filing, send a corrected form with the CORRECTED box checked and an updated copy to the recipient, and fixing it before August 1 keeps any penalty in the lowest tier.
Reporting interest on your return?
A 1099-INT lands on your Form 1040, on the interest lines, and on Schedule B once your interest tops $1,500. Whichever form you need to report or produce, it's a click away, with the same plain-language approach.
The questions people ask most about the boxes, what's taxable, the federal-versus-state split, and the deadlines.
Form 1099-INT, Interest Income, is an information return a payer files to report interest it paid you during the year: interest from a bank or credit union account, a CD, a corporate bond, U.S. Treasury or savings bonds, and tax-exempt municipal bonds. You get a copy so you can report the interest on your return, and the IRS gets a copy too.
Because a bank, credit union, brokerage, or other payer paid you $10 or more in interest during the year, which is the threshold for box 1, box 3, or box 8. Interest on a savings or checking account, a CD, Treasury or savings bonds, and municipal bonds all come on a 1099-INT. Interest a business pays you in other situations, like on a legal settlement or a delayed death benefit, can also appear here.
Yes. The $10 figure is the payer's filing threshold, not your reporting threshold. You have to report all of your taxable interest on your federal return, even a few dollars, and even if no 1099-INT ever arrives. If a form didn't come, total the interest from your account statements and report it. The IRS still expects the income.
It depends on the box. Ordinary interest in box 1 is taxable on both your federal and state returns. Treasury and savings bond interest in box 3 is taxable federally but exempt from state and local tax. Tax-exempt interest in box 8, usually from municipal bonds, isn't taxed on your federal return, though you still report it and your state may tax it if the bonds are from another state.
They separate interest by how it's taxed. Box 1 is ordinary taxable interest, like from a bank account or CD, taxable everywhere. Box 3 is U.S. Treasury and savings bond interest, taxable on your federal return but exempt from state and local tax. Box 8 is tax-exempt interest, usually municipal bond interest, not taxed federally. Keeping them apart is the whole point of the form, so the right rule applies to each.
On your federal return, yes, box 8 interest isn't taxed, but you still report it on the tax-exempt interest line of Form 1040. It can matter in two ways: your state may tax municipal interest from other states, and tax-exempt interest counts when figuring how much of your Social Security is taxable. Box 9 shows any part that's a specified private activity bond, which can be subject to the alternative minimum tax.
Box 2 shows a penalty the payer charged you for taking money out of a time deposit, like a CD, before it matured. It's not tax withheld. It's a deduction: you claim the box 2 amount as an adjustment to income on Schedule 1 of Form 1040, which lowers your taxable income even if you don't itemize.
You file Schedule B (Form 1040) when your total taxable interest is more than $1,500, or in a few other cases like nominee interest. Below $1,500 you can usually put the total straight on the interest line of Form 1040 without the schedule. Even under $1,500, the interest still has to be reported.
A 1099-INT is generally required for $10 or more of interest in box 1, box 3, or box 8. The recipient copy is generally due January 31, though a broker's composite statement that includes a 1099-INT can be furnished by February 15. The IRS copy is due by the end of February on paper or March 31 if you e-file, and a due date on a weekend or holiday moves to the next business day. Anyone filing 10 or more information returns of any type combined has to e-file.
No. The generator builds a completed, downloadable Form 1099-INT that you can preview free, then you e-file it through the IRS system or print and mail it. It's a document tool, not an e-file transmitter, so you stay in control of when and how it's filed.
