Missed Form 5472? Late Filing and Penalty Relief (2026)
If your foreign-owned LLC never filed Form 5472, or filed it late, you are not alone. The penalty is serious, but filing now and explaining why can make a real difference. Here is what to do, step by step, and how our CPA-led team handles late filings.
If you missed Form 5472, file every missing year as soon as possible with a pro forma Form 1120, and include a reasonable-cause statement if your situation supports one. The penalty is $25,000 per late or missing form, plus more if the IRS sends a notice and it stays unfiled after 90 days, but the IRS can waive penalties for reasonable cause.
What Happens if You Do Nothing
- The base penalty is $25,000 for each Form 5472 that is late, missing or substantially incomplete.
- If the IRS sends a notice and the form is still missing 90 days later, another $25,000 can be added for each further 30 days.
- Penalties apply even when the LLC owed no tax and made no money.
Your Options, Missed One Year vs Several
| Situation | What we usually recommend |
|---|---|
| Missed one year, no IRS letter yet | File the missing year now with a reasonable-cause statement if it applies |
| Missed several years | File every missing year together, each with its own pro forma 1120 |
| Received an IRS penalty notice | Respond before the deadline in the letter; ask for penalty relief with the late forms |
| LLC already closed | File the missing years and a final-year return, then close properly |
Step by Step
- Collect bank statements for each missed year.
- List money the owner put in and took out, and other related-party transactions.
- Prepare Form 5472 and a pro forma 1120 for each year.
- Write a short, factual reasonable-cause statement if your circumstances support it.
- Send the forms the way the IRS requires for foreign-owned disregarded entities, and keep proof.
- Keep a calendar so next year’s April 15 deadline is not missed.

Late Form 5472: FAQs
I missed Form 5472 last year. What should I do?
File the missing forms as soon as possible with a pro forma Form 1120 for each year, and keep records of the LLC’s transactions. Filing late is better than not filing, because the penalty also grows if the IRS sends a notice and the form is still missing 90 days later.
Will the IRS always charge the $25,000 penalty?
The penalty for a late, missing or substantially incomplete Form 5472 is $25,000 per form. The IRS can remove or reduce penalties when there is reasonable cause, so a clear written explanation filed with the late forms matters.
What counts as reasonable cause?
Generally, circumstances beyond your control despite ordinary care, such as serious illness, disasters or reliance on wrong professional advice. “I did not know” is usually not enough on its own. Our CPA reviews your situation before anything is sent.
I missed several years. Do I file all of them?
Usually yes, one pro forma 1120 with Form 5472 for each missed tax year. We prepare them together from your bank statements.
My LLC is closed. Do I still need to file?
Yes, for every year the LLC existed and had reportable transactions, including a final-year filing. See how to close an LLC.
