Missed a filing year? Use GatewayBase to prepare a supported Form 1120 + 5472 filing. GatewayBase helps with filing workflow, but it does not guarantee penalty relief.
The Form 5472 penalty is serious. The IRS can assess a $25,000 penalty when a reporting corporation does not file a complete and correct Form 5472 by the due date.
For foreign-owned US LLC owners, this can be surprising. Many owners believe that if their LLC had no profit or no US tax due, there is no filing problem. But Form 5472 is an information return. It can be required even when no income tax is owed.
This article explains why the penalty happens, what makes Form 5472 different, and what to do if you missed a filing year.
This is general education, not tax advice. GatewayBase provides document preparation and filing workflow software. We are not a law firm, CPA firm, or tax advisor.
Why the penalty exists
The IRS uses Form 5472 to collect information about certain transactions between a reporting corporation and related parties.
For many foreign-owned single-member US LLCs, the LLC is a disregarded entity for normal income tax purposes. But for Form 5472 reporting rules, a foreign-owned US disregarded entity is treated as a separate corporation for limited reporting purposes.
That is why a small LLC owned by a non-US person can still have a Form 5472 requirement.
The penalty is attached to the information reporting requirement, not only to income tax due.
How much is the Form 5472 penalty?
As of the 2026-07-08 source check, IRS guidance says the penalty for failing to file a complete and correct Form 5472 by the due date can be $25,000 for each failure.
The IRS also says additional continuation penalties can apply if the IRS sends a notice and the form is still not filed within the required time.
This is why ignoring the issue can be risky. A missed filing year should usually be dealt with directly, not left for later.
Incomplete Form 5472 filings can also be a problem
The penalty is not only about missing the form completely.
The IRS instructions say a substantially incomplete Form 5472 can be treated as a failure to file. In simple words, sending a form with important missing information may not protect you.
Common incomplete or risky filings include:
- Missing the related party details.
- Missing the EIN.
- Missing reportable transactions.
- Filing without the pro forma Form 1120 when required.
- Using the wrong filing method.
- Filing for the wrong tax year.
- Leaving large required sections blank because the owner did not understand them.
This is one reason a guided workflow can help. The hard part is often knowing which questions matter.
Why no tax due does not remove the risk
Many foreign-owned LLCs owe no US income tax in a simple year. That may be true for some owners, but it does not automatically remove Form 5472 reporting.
Form 5472 reports activity. Examples can include:
- Capital contributions.
- Loans between the owner and the LLC.
- Owner-paid startup costs.
- Payments to or from a foreign related party.
- Other transfers between the LLC and the owner.
If those transactions happened, the LLC may need to file even if the company had no revenue or no profit.
What to do if you missed Form 5472
If you missed a Form 5472 filing year, do not assume the problem will fix itself.
A practical next step is:
- Identify the tax year that was missed.
- Confirm whether the LLC had reportable transactions for that year.
- Gather the LLC name, EIN, address, owner details, and transaction records.
- Prepare the missing pro forma Form 1120 and Form 5472 if required.
- Keep proof of filing.
- If you received an IRS notice, read the deadline carefully and consider professional help.
GatewayBase can help with supported filing years and supported entity types. In the current repo, GatewayBase supports Form 1120 years 2023, 2024, and 2025. The late-filing option is currently $49, but pricing should be checked before publishing.
Why filing proof matters
When you send a filing, keep evidence that it was sent.
For foreign-owned US disregarded entities, IRS instructions describe special filing methods and a dedicated address or fax path. The normal Form 1120 filing address is not the same path for these filers.
GatewayBase helps by saving filing records and fax confirmation proof in the file vault. That proof can be useful if you later need to show when the filing was sent.

FAQ
Is the Form 5472 penalty really $25,000?
Yes. Current IRS penalty guidance lists a $25,000 penalty for each failure to file a complete and correct Form 5472 by the due date.
Can the penalty apply if my LLC had no income?
Yes, it can. Form 5472 is about reportable transactions, not only income. No income does not always mean no filing.
What if I filed Form 5472 but made mistakes?
A substantially incomplete Form 5472 can still be treated as a failure to file. If you know a filing was wrong or incomplete, consider getting professional advice.
Can GatewayBase remove a penalty?
No. GatewayBase prepares documents and supports the filing workflow. It does not remove IRS penalties or provide legal or tax representation.
Should I file late if I missed the deadline?
Usually, ignoring a missed filing is worse than dealing with it. If GatewayBase supports the year and your entity type, you can use the late-filing workflow. If you received an IRS notice, consider professional advice.
