Form 5472 Penalties: What Happens If You Don’t File
Last updated October 27, 2026
Quick answer
If a foreign-owned U.S. LLC or a 25% foreign-owned corporation doesn’t file Form 5472 on time, files it substantially incomplete, or doesn’t keep the required records, the IRS can charge $25,000 per form, per year. If the failure continues more than 90 days after an IRS notice, another $25,000 applies for every 30 days, with no maximum. It applies even when the company owes no tax. Filing late beats not filing, and relief is possible with reasonable cause.

Who can be penalized
• Foreign-owned U.S. single-member LLCs (disregarded entities) that had reportable transactions with their owner and didn’t file
• U.S. corporations at least 25% foreign-owned, and foreign corporations doing business in the U.S., that must attach Form 5472 to their return
• Companies that filed but left out required information — a substantially incomplete form is treated like a missing one

How to avoid — or fix — a Form 5472 penalty
1. Check every year you had to file
Look back over each year since the company was formed. Any money or property moving between the company and its owner — including the owner paying formation or state fees — generally means a Form 5472 was due for that year.
2. File on time, or extend
File the pro forma Form 1120 with Form 5472 by April 15 for a calendar-year company, or file Form 7004 by that date for an automatic six-month extension to October 15.
3. Make the form complete
Fill in every required item: the owner’s identifying details and tax IDs, country information and the amount of each type of reportable transaction. A form missing required information can be penalized as if it had not been filed.
4. If you missed a year, file now
File the missing returns as soon as possible. If the IRS hasn’t contacted you or opened an examination, its Delinquent International Information Return Submission Procedures let you file late forms with a statement explaining why they were late.
5. Respond to any penalty notice
If you receive a penalty notice, reply by the date on it. You can ask for the penalty to be removed with a written reasonable-cause statement that sets out the facts and shows you acted in good faith — a tax professional can help prepare it.
6. Keep records that back up the numbers
Keep bank statements, invoices and loan agreements for every transaction with the owner and other related parties, so the amounts you report can be supported.
Form 5472 penalties: frequently asked questions
How much is the penalty for not filing Form 5472?
$25,000 for each Form 5472 that isn’t filed on time or is substantially incomplete, for each tax year. If the failure continues more than 90 days after the IRS mails a notice, an additional $25,000 is charged for each 30-day period, with no maximum.
Is there a penalty if my LLC had no income and owes no tax?
Yes. Form 5472 is an information return, so the penalty doesn’t depend on tax owed. What matters is whether there were reportable transactions with the owner — such as the owner funding the company or paying its fees.
Is the penalty per form or per company?
Per form. A separate Form 5472 is generally required for each related party the company had reportable transactions with, and the $25,000 penalty can apply to each one, for each year.
Can the IRS still charge the penalty if I file late on my own?
Yes, a late filing is still a failure to file on time. Filing as soon as possible with a reasonable-cause statement gives you the best chance of avoiding or reducing the penalty, and stops the continuing penalty from building up after a notice.
What counts as reasonable cause?
The IRS looks at whether you used ordinary business care and prudence but still couldn’t comply — for example, because of circumstances beyond your control or reliance on incorrect professional advice. Simply not knowing about the requirement may not be enough on its own; each case depends on its facts.
Can I just start filing this year and skip the years I missed?
Each missed year carries its own penalty exposure, and the IRS’s time limit to assess those years generally doesn’t start until the information is filed. Bringing the missing years up to date is usually the safer path — ideally with a tax professional.
