Missing a required Form 1099-INT filing can be costly if a payer files late, leaves out required information, reports the wrong recipient TIN, or skips the form completely, the IRS may charge information return penalties.
For the 2026 tax year, payers should look at Form 1099-INT risk in four parts: the IRS filing, the recipient copy, the accuracy of the data, and the intent behind the mistake. A late form is one issue. A wrong TIN is another. Ignoring the filing requirement is the highest-risk situation.
This guide explains when a Form 1099-INT penalty may apply, how penalty tiers work, and what payers can do to reduce risk.
When Can a Form 1099-INT Penalty Apply?
A penalty may apply when a payer does not file Form 1099-INT when required. It may also apply when the form is filed late or with incorrect details.
Common triggers are:
- Not filing Form 1099-INT with the IRS
- Filing after the due date
- Leaving out required information
- Reporting an incorrect recipient TIN
- Filing with the wrong interest amount
- Filing on paper when eFiling is required
- Not furnishing the recipient statement
- Intentionally disregarding IRS filing rules
Form 1099-INT is generally required when a payer pays at least $10 in reportable interest for boxes 1, 3, or 8. It may also be required when the payer withholds and pays foreign tax on interest, or withholds federal income tax under backup withholding rules, even if the payment is below the usual reporting threshold. For 2026 returns, certain trade-or-business interest payments that were previously reportable at $600 are reportable at $2,000.
Penalties for Not Filing Form 1099-INT
The IRS applies different penalty amounts depending on when the correct information return is filed. The later the correct filing happens, the higher the penalty can be.
The IRS currently lists the following amounts for information returns due in calendar year 2026:
| Filing failure timing | Penalty per return or statement |
|---|---|
| Up to 30 days late | $60 |
| 31 days late through August 1 | $130 |
| After August 1, or not filed | $340 |
| Intentional disregard | At least $680 |
Important note: These figures are for information returns due in calendar year 2026. Since 2026 tax year, Forms 1099-INT are generally filed in 2027, payers should use the IRS penalty amounts for returns due in 2027 before applying the final penalty amounts.
Why Form 1099-INT Penalties Can Add Up Fast
Information return penalties are calculated separately for each incorrect or late IRS return and each incorrect or late recipient statement. That means that while one missed Form 1099-INT may be manageable, a group of missed forms can become expensive.
For example, a lender that misses 80 required Form 1099-INT records may face a penalty for each missing IRS return. If the recipient copies were also not furnished correctly and on time, separate payee statement penalties may apply.
This is why Form 1099-INT preparation should not wait until the last week of January. Payers need enough time to review interest totals, verify TINs, prepare forms, and fix record gaps.
Form 1099-INT Deadlines
For 2026 tax-year returns filed in 2027, Form 1099-INT has three key due dates.
| Filing task | Statutory deadline | Actual deadline for 2026 tax-year forms |
|---|---|---|
| Furnish recipient copy | January 31 | February 1, 2027 |
| File paper copy with the IRS | February 28 | March 1, 2027 |
| eFile with the IRS | March 31 | March 31, 2027 |
January 31 and February 28 fall on Sundays in 2027, so those deadlines move to the next business day for the 2026 tax-year Forms 1099-INT.
The recipient copy deadline and IRS filing deadline are separate. A payer can file with the IRS on time and still face risk if the recipient statement was not furnished correctly.
What Happens If You File Late?
A late Form 1099-INT should be filed as soon as possible. Waiting can move the filing into a higher penalty tier.
A late or incorrect form filed correctly within 30 days after the due date generally carries a lower penalty than one filed after August 1. A form that is never filed falls into the higher standard penalty tier. If the IRS believes the payer deliberately ignored the rule, intentional disregard penalties may apply.
The IRS may also charge interest on penalties until the balance is paid.
Not Filing vs. Filing Incorrectly
Some payers only worry about missed filings. Incorrect filings can also trigger penalties.
Common accuracy issues include:
- Reporting tax-exempt interest in the wrong box
- Leaving out backup withholding
- Using an incorrect recipient TIN
- Reporting the wrong interest amount
- Filing a duplicate form for the same payment
- Using Form 1099-INT for dividends that belong on Form 1099-DIV
- Missing foreign tax withheld and paid on interest
If an error is found after filing, prepare a corrected Form 1099-INT as soon as possible.
How to Reduce Penalty Risk After a Missed or Incorrect 1099-INT
If a payer discovers a missed Form 1099-INT, the response should be quick and organized.
Firstly, make sure that Form 1099-INT was required. Check the $10 interest reporting rule, the 2026 $2,000 rule for certain trade-or-business interest payments, backup withholding, foreign tax withheld and paid on interest, and any exempt-recipient rules.
Then, get the missing return filed as soon as possible. This can help keep the issue in the lowest possible penalty tier.
It’s important to furnish the recipient statement if that was also missed. Keep a record of when the issue was found, when the form was filed, and when the recipient statement was furnished.
Coming to inaccurate filings, there are a few things to note. If the error involved a TIN, payee name, or amount, you’ll need to review whether a corrected return is needed. TIN errors and payee surname errors are never treated as inconsequential for IRS return penalties, and dollar amount errors may need correction unless a safe harbor applies.
In case the IRS sends Notice 972CG proposing penalties, review the notice and act promptly. Payers who believe they have reasonable cause should document what happened, show that they acted responsibly before and after the failure, and keep supporting records.
What to Do If You Missed a Form 1099-INT Filing
Do not ignore the missed form. File it, furnish the recipient copy, and correct the records.
If backup withholding should have applied because the recipient did not provide a TIN, or because the IRS notified the payer that the TIN was incorrect, review the account and begin backup withholding where required. Any backup withholding taken must also be reported on Form 1099-INT and Form 945.
If there are penalties, follow the instructions on the notice. Penalty relief may be available if the payer can show reasonable cause and prove that the failure was not due to willful neglect.
OBBBA Update for Form 1099-INT
The One Big Beautiful Bill Act changes some information reporting thresholds for tax years beginning after 2025. Payers should not assume that one threshold applies to all 1099 forms.
For Form 1099-INT, IRS 2026 guidance still lists the $10 threshold for many types of interest, with a $2,000 threshold for certain trade-or-business interest payments. Backup withholding and foreign tax withheld and paid on interest can also require filing, even if the payment is below the usual threshold.
The best approach is to verify the specific Form 1099-INT rule before deciding that a form is not required.

FAQs
1. Does every interest payment require Form 1099-INT?
No. Not every interest payment requires Form 1099-INT. Generally, for 2026 returns, you must file Form 1099-INT if you paid a recipient at least $10 in reportable interest, such as regular interest income, interest on U.S. Savings Bonds and Treasury obligations, or tax-exempt interest. You must also file Form 1099-INT if you withheld and paid foreign tax on interest, or if backup withholding was taken from the interest payment, even when the payment was below the normal Form 1099-INT reporting amount.
Certain interest payments made in the course of a trade or business that were previously reportable at $600 are reportable at $2,000 for 2026 returns.
2. Can penalties apply if only the recipient copy was missed?
Yes. IRS filing penalties and recipient statement penalties are independent of each other. Penalty exposure can still exist if one of the requirements is missed.
3. What if paper forms were mailed when eFiling was required?
Filing on paper when eFiling is required may lead to penalties unless the filer has an approved waiver.
4. Is it possible for the IRS to waive a 1099-INT penalty?
Yes, but only if the filer qualifies for penalty relief. The IRS may remove or reduce the penalty if the filer can show that there was reasonable cause for the delayed or missed filing, explain the steps taken to prevent or fix the issue, and also show that the failure was not willful.
5. Is there a penalty cap for intentional disregard?
No. The IRS does not set a maximum penalty for intentional disregard.
Conclusion
For information returns due in calendar year 2026, IRS penalties range from $60 to $340, with a higher minimum penalty for intentional disregard. The exact penalty figures, however, can depend on what went wrong, how late the filing was, and whether the payer ignored the rule on purpose. Late forms, incorrect TINs, incorrect amounts, and filing on paper when eFiling is required can all lead to penalties.
The best way to reduce Form 1099-INT penalty risk is to be prepared with all the data early, check recipient TINs, eFile using a trusted provider when eFiling is required, send recipient copies on time, and correct errors as early as possible.
