Failure-to-File Penalty

« Back to Glossary Index

The failure-to-file penalty is an IRS penalty charged when a required tax return is filed after the deadline, including extensions. For U.S. expats, it can apply when Form 1040 or another required return is filed late and unpaid tax is due.

Why it matters for U.S. expats

The failure-to-file penalty is usually more expensive than the failure-to-pay penalty, so filing matters even when you cannot pay the full balance right away. U.S. expats also need to track the automatic June 15 filing extension, the regular payment deadline, Form 4868 extensions, and any late foreign income or international reporting issues that may require a broader compliance strategy.

Common questions

1. When does the failure-to-file penalty apply?

The penalty applies when a required tax return is filed after the due date, including any valid extension, and there is unpaid tax due.

2. How much is the failure-to-file penalty?

For individual returns, the penalty is 5% of the unpaid tax for each month or partial month the return is late, up to 25%.

3. Is there a minimum failure-to-file penalty?

Yes. If a return is more than 60 days late, the minimum penalty applies. For returns due after December 31, 2025, the minimum penalty is $525 or 100% of the unpaid tax, whichever is less.

4. Does the failure-to-file penalty apply if no tax is owed?

No. The failure-to-file penalty is based on unpaid tax, so it does not apply when there is no unpaid tax due. Other penalties can still apply for missed international forms, FBARs, or information returns.

5. Is the failure-to-file penalty different from the failure-to-pay penalty?

Yes. The failure-to-file penalty is for filing late. The failure-to-pay penalty is for paying late, even if the return was filed on time.

6. What happens if both failure-to-file and failure-to-pay penalties apply?

When both penalties apply in the same month, the failure-to-file penalty is reduced by the failure-to-pay penalty for that month.

7. Does the automatic expat extension prevent the failure-to-file penalty?

Yes, if the return is filed by the automatic June 15 expat deadline. Tax still needs to be paid by the regular April deadline to avoid interest and possible late-payment penalties.

8. Can Form 4868 prevent the failure-to-file penalty?

Yes. Form 4868 can extend the filing deadline to October 15, but it does not extend the time to pay tax.

9. Can the failure-to-file penalty be removed?

Yes, if the taxpayer qualifies for penalty relief. The IRS may remove or reduce the penalty for reasonable cause, first-time penalty abatement, or another applicable relief route.

10. What should U.S. expats do if they have not filed in years?

They should review whether they need normal late filing, amended returns, Streamlined Filing Compliance Procedures, Delinquent FBAR Submission Procedures, or another compliance route before submitting returns.
