Form 5472 Penalty: The $25,000 IRS Penalty Explained (2026)
By Arik Rozen, CPA, MBA -- Form5472.online | September 2026
THE SHORT ANSWER
The IRS penalty for a missing, late, or substantially incomplete Form 5472 is $25,000 per year, per form -- automatic, with no grace period, no minimum revenue threshold, and no exception for inactive LLCs. It applies even if your LLC had zero income and zero transactions during the year.
If you have already missed a filing, there is a legal path to penalty removal called Reasonable Cause abatement. It works -- but it requires a CPA-drafted explanation submitted correctly to the IRS. Read on for exactly how the penalty works and what your options are.
What Is the Form 5472 Penalty?
Form 5472 is an information return required for foreign-owned U.S. disregarded entities -- most commonly, a single-member LLC owned by a non-U.S. person. It must be filed together with a pro forma Form 1120 by April 15 each year (or October 15 with an extension).
The IRS penalty for failing to file Form 5472 -- or filing it late, or filing it in a substantially incomplete manner -- is set out in Internal Revenue Code Section 6038A(d):
$25,000 per failure, per year. This is the initial penalty. If the failure continues for more than 90 days after the IRS mails a notice of the failure, an additional penalty of $25,000 applies for each 30-day period (or fraction thereof) of continued non-compliance. There is no statutory maximum on the continuation penalty.
This is not a percentage of tax owed. It is a flat dollar amount that applies regardless of the size of the LLC, its revenue, or whether any tax was due. A foreign-owned LLC that was completely inactive and had no income, no expenses, and no transactions still owes the $25,000 penalty if Form 5472 was not filed.
How the Penalty Compounds
Most people who receive a Form 5472 penalty notice are surprised by the total amount. Here is how it works in practice:
Situation | Penalty amount |
1 year missed, caught immediately | $25,000 |
1 year missed, IRS notice ignored for 90+ days | $25,000 + $25,000 per 30-day period of continued non-compliance |
3 years missed (common for new LLC owners) | $75,000 minimum -- before continuation penalties |
Substantially incomplete filing (wrong or missing data) | Same $25,000 as a missing filing |
Multiple related parties (separate Form 5472 required for each) | $25,000 per form, per year |
The most common scenario we see: a foreign founder opens a U.S. LLC, is told it is "inactive" and does not need to file anything, and discovers two or three years later that the IRS disagrees. The total penalty exposure in that situation is $75,000 or more before any continuation penalties are added.
What Triggers the Penalty?
There are three situations that trigger the Form 5472 penalty:
1. Failure to file
The most common trigger. If Form 5472 (attached to a pro forma Form 1120) is not filed by the deadline -- or not filed at all -- the $25,000 penalty applies automatically for each year of non-filing.
2. Late filing
Filing Form 5472 after the April 15 deadline (or October 15 with extension) triggers the same $25,000 penalty as not filing at all. There is no reduced penalty for "close" late filings.
3. Substantially incomplete filing
A Form 5472 that is filed on time but contains material omissions or incorrect information is treated as a failure to file. This includes forms that omit required reportable transactions, use incorrect amounts, or fail to properly identify the related party.
One misconception worth addressing: many foreign founders believe that if their LLC had no income and no U.S. bank account, there is nothing to report and no filing obligation. This is incorrect. The filing obligation for a foreign-owned disregarded entity exists regardless of activity level. Even a capital contribution from the foreign owner to the LLC -- which occurs in virtually every LLC formation -- is a reportable transaction that requires a Form 5472.
Does the Penalty Apply to Inactive LLCs?
Yes. This is the question I am asked most often, and the answer is consistently misunderstood.
A foreign-owned U.S. disregarded entity is required to file Form 5472 for every year in which it existed, regardless of whether it had income, expenses, customers, or a U.S. bank account. The IRS does not provide an exemption for inactive or dormant entities.
The only exception is a foreign-owned disregarded entity that had absolutely no reportable transactions during the tax year AND was not formed or dissolved during that year AND had no capital contributions or distributions. In practice, this exception applies to very few LLCs -- the initial capital contribution at formation is itself a reportable transaction that triggers the filing requirement for at least the first year.
What Happens After You Receive an IRS Penalty Notice?
If the IRS has already assessed a Form 5472 penalty against you, you will typically receive a CP notice by mail. The notice will state the penalty amount and give you a deadline to respond -- usually 30 to 60 days.
At this point, you have two options:
Option 1 -- Pay the penalty
This is the path of least resistance, but in most cases it is the wrong choice. The IRS penalty abatement process exists precisely for situations like this, and a well-prepared Reasonable Cause statement has a high rate of success when submitted correctly.
Option 2 -- Request penalty abatement
A Reasonable Cause penalty abatement request argues that the failure to file was due to circumstances beyond the taxpayer's control -- typically, a genuine misunderstanding of the filing obligation that was reasonable given the facts. The IRS has broad discretion to grant abatement when the facts support it.
Important: "First Time Abatement" -- the standard administrative waiver available for most income tax penalties -- does not automatically apply to Form 5472 penalties. The applicable relief mechanism is Reasonable Cause, which requires a facts-and-circumstances analysis specific to your situation. A generic penalty abatement request is unlikely to succeed.
Can the Form 5472 Penalty Be Removed?
Yes -- in many cases. The IRS grants Reasonable Cause abatement for Form 5472 penalties when the taxpayer can demonstrate that the failure to file was due to circumstances that would lead a reasonable, prudent person to believe the filing was not required.
The strongest Reasonable Cause arguments for Form 5472 typically involve:
Reliance on a tax professional who failed to advise the client of the filing obligation
Genuine, documented lack of knowledge of the U.S. filing requirement for a foreign entrepreneur with no prior U.S. tax experience
An LLC formation agent or registered agent who did not inform the foreign owner of ongoing filing obligations
A reasonable belief -- based on the LLC's inactivity -- that no U.S. tax filing was required
At Form5472.online, our historical penalty removal rate for clients we classify as eligible for abatement assistance is 98%, based on our own company records. This figure is not an IRS statistic, has not been independently audited, and does not predict the outcome of any individual case. But it reflects what a well-prepared, CPA-drafted Reasonable Cause submission can achieve when the facts support it.
What Does Penalty Removal Cost?
Our penalty removal service works in two steps:
Step 1 is the delinquent filing itself -- preparing and filing the missing Form 5472 and pro forma Form 1120 for each year that was missed. The IRS requires the delinquent returns to be on file before it will consider a penalty abatement request. Our filing fee is $448 all-in for a non-active single-member LLC per year.
Step 2 is the penalty abatement -- a CPA-drafted Reasonable Cause statement, customized to your specific facts, submitted to the IRS with the abatement request. Our flat fee for this service is $499, which covers all years included in the same engagement.
For a single-year case involving a non-active SMLLC, the total is $947. That compares to a $25,000 IRS penalty -- or $75,000 for three missed years -- that may be fully removed.

What If I Have Multiple Missed Years?
Multiple missed years are more common than most people expect, and they are fully manageable. The IRS Delinquent International Information Return Submission Procedures (DIIRSP) provide a formal pathway for submitting multiple years of delinquent Form 5472 filings together with a single Reasonable Cause statement.
We handle multi-year cases routinely. The $499 penalty removal service fee covers all years submitted in the same engagement -- you do not pay $499 per year, only per engagement. The filing fee ($448 per year for a non-active SMLLC) applies to each year separately.
Frequently Asked Questions
Can the IRS waive the Form 5472 penalty?
Yes. The IRS has discretion to abate the Form 5472 penalty under Internal Revenue Code Section 6038A(e) when the taxpayer establishes Reasonable Cause and absence of willful neglect. The IRS does grant these abatements -- but only when a properly prepared request is submitted with the delinquent returns.
What if my LLC was genuinely inactive?
Inactivity does not eliminate the filing requirement, but it may strengthen a Reasonable Cause argument. A foreign founder who formed an LLC, never used it for any business activity, and genuinely believed no filing was required has a reasonable argument that the failure was not willful. A CPA can assess whether your specific facts support abatement.
How long does penalty abatement take?
The IRS typically takes 6 to 12 months to respond to a Reasonable Cause abatement request submitted with delinquent returns under the DIIRSP procedures. The process requires patience, but it is a formal IRS procedure, not a negotiation.
What if I already paid the penalty?
You can still file for abatement after paying. If the abatement is granted, the IRS will issue a refund. The deadline for filing an abatement claim after payment is generally three years from the date of payment.
Do I need a CPA or can I do this myself?
You can submit a Reasonable Cause request yourself -- there is no legal requirement for professional representation. However, the quality of the Reasonable Cause statement is the primary factor in whether the abatement is granted. A generic or poorly drafted statement will likely be denied. A CPA who has handled multiple Form 5472 abatement cases will know what arguments the IRS finds persuasive and how to document them correctly.
