The Form 5472 penalty is $25,000, and it does not depend on income
Failing to file Form 5472 when due costs $25,000. Filing late costs $25,000. Filing a substantially incomplete form costs $25,000, because the instructions treat it as not filing. The penalty has nothing to do with what the company earned, so an LLC that made nothing owes the full amount. The rules, per the Instructions for Form 5472 (Rev. 12-2024):
- Initial penalty: $25,000 for failure to file when due and in the manner prescribed
- "Filing a substantially incomplete Form 5472 constitutes a failure to file Form 5472"
- After IRS notice: An additional $25,000 "with respect to each related party for which a failure occurs for each 30-day period (or part of a 30-day period)" once 90 days pass, with no stated ceiling
- The same $25,000 applies separately to failure to maintain records under Regulations section 1.6038A-3
- Criminal penalties under sections 7203, 7206, and 7207 can apply for willful failure or false filings

Who must file and how the filing works is covered in our main Form 5472 guide for foreign founders, and what belongs on the form in Form 5472 reportable transactions. This page covers what it costs to get it wrong.
The initial $25,000, three ways to earn it
The instructions assess the penalty on any reporting corporation that fails to file Form 5472 when due and in the manner prescribed. That single sentence covers three failures:
- Not filing. The obvious one.
- Filing late. The deadline is the income tax return’s due date, including extensions. A day past it is a failure.
- Filing incomplete. "Filing a substantially incomplete Form 5472 constitutes a failure to file Form 5472." A form with guessed numbers outside the reasonable-estimate band, or missing parts, is not a discount version of compliance. It risks being treated as substantially incomplete, which the instructions say constitutes a failure to file: $25,000, same as silence.
The amount is fixed. It is not a percentage of tax owed, because this is an information return: There is usually no tax on it at all. A foreign-owned single-member LLC that earned nothing, owed nothing, and had one reportable transaction owes the same $25,000 as a company with a million in revenue.
The escalation clock
The initial penalty is the floor. If the failure continues for more than 90 days after the IRS mails notice of it, an additional $25,000 applies, and the instructions are specific about how it multiplies: "with respect to each related party for which a failure occurs for each 30-day period (or part of a 30-day period) during which the failure continues after the 90-day period ends."
Read the multipliers. Per related party. Per 30-day period. Part of a period counts as a period. No stated ceiling. A single ignored notice, one related party, and six months of drift is the initial $25,000 plus three more periods: $100,000. The clock only runs after notice, which is exactly why waiting for the notice is the expensive strategy.
The records exposure most owners miss
There is a second, independent way to the same penalty. The reporting corporation must maintain the records that substantiate the filing, and the instructions state the $25,000 penalty "also applies for failure to maintain records as required by Regulations section 1.6038A-3."
A filed form with nothing behind it is not safety. The records duty is why the transaction trail matters as much as the form: what counts as reportable, and the records that survive an exam, is its own discipline. The practical difference shows up at gathering time. Most services have you hunt down a year of statements and email them in, and whatever you cannot find is a hole in the file. On a platform like looch, the transaction record already exists in the app, external bank, card, and investment accounts included, because those are accounting-enrolled and their activity flows in automatically. The substantiation is a byproduct of the books, not an annual archaeology project.
Criminal exposure, stated once
For willful failure to submit information, or for filing false or fraudulent information, "criminal penalties under sections 7203, 7206, and 7207 may also apply." That sentence exists in the instructions for a reason. This page is about the civil penalty; willfulness is a different category with a different professional standing next to you, and nothing here is legal advice.
If you have already missed a year
Do not wait for the notice. The escalation clock starts 90 days after the IRS mails it, and every 30 days after that is another $25,000 per related party.
A missed year is not a form-preparation problem. It is a penalty-relief problem, usually a reasonable-cause argument, and that is work for a qualified tax professional, an enrolled agent, a CPA, or an attorney. Get one before the IRS contacts you, while the record still supports the argument. The service described below is for current-year filings; it is not a fix for a missed year, and anyone who sells it as one is selling the checkbox our main guide warns about.
The same guide lists who needs a CPA even for the current year: Multi-member LLCs, corporations with real tax to compute, effectively connected income or a US trade or business, and any prior-year cleanup.
Filing on time, prepared
The penalty is avoidable on the plain, current-year case: One US single-member LLC, one foreign owner, filed on time with real numbers and records behind them. looch prepares that filing, the pro forma Form 1120 with Form 5472 attached, prepared and signed by an IRS PTIN holder as paid preparer, for $399 per filing on the looch pricing page. A foreign-owned disregarded entity cannot e-file this return and must follow the submission method in the IRS instructions. If the entity does not exist yet, looch Start forms it and obtains the EIN, with no SSN or ITIN required.
