The $25,000 Letter: What to Do If the IRS Penalizes Your Foreign-Owned LLC for a Late Form 5472

Every spring, foreign-owned single-member US LLCs are required to file Form 5472, attached to a pro forma Form 1120, by April 15. And every summer, some of their owners open a letter from the IRS — often a notice called CP215 — announcing a penalty of $25,000.

If that letter has arrived, or if you have just realised you missed this year's deadline, this guide explains what the penalty actually is, how it grows if you ignore it, and the realistic routes to getting it reduced or removed. Everything below is based on the IRS's own published rules.

Why the Penalty Is $25,000 — and Why It Can Be Assessed Automatically

Under Internal Revenue Code Section 6038A, a US company that is at least 25% foreign-owned — including a single-member LLC owned by a non-resident, which is treated as a foreign-owned disregarded entity — must report its transactions with related parties on Form 5472 each year.

The penalty for failing to file a complete and correct Form 5472 by the due date is $25,000 per form, per year. Two things surprise owners most. First, the penalty has nothing to do with tax owed: it applies even if your LLC made no profit and owes zero US tax. Second, it can be assessed without any audit — the IRS can simply issue the penalty when it identifies a missing or late form, and many owners first learn about it from the CP215 notice itself.

How the Penalty Grows If You Ignore It

The initial $25,000 is not the ceiling. If the IRS mails you a notice about the failure and you still do not file the form within 90 days, an additional continuation penalty of $25,000 applies for each 30-day period after that 90-day window expires. Unlike some other international information return penalties, the IRS states there is no maximum amount for Form 5472 continuation penalties.

The IRS also charges interest on penalties, and interest keeps accruing until the balance is paid in full — or until the penalty itself is removed.

Step 1: File the Missing Form Immediately

Whatever else you decide to do, file the delinquent Form 5472 with its pro forma Form 1120 as soon as possible. Filing stops the 90-day continuation clock from turning one penalty into several. Form 5472 for a foreign-owned disregarded entity cannot be e-filed; it goes by mail or fax to the IRS's Ogden, Utah service centre, with "Foreign-owned U.S. DE" written across the top of the pro forma 1120.

Step 2: Reasonable Cause — the Main Route to Relief

The IRS may remove or reduce the penalty if the failure was due to reasonable cause and not wilful neglect. In the IRS's own words, you may have reasonable cause if you acted responsibly both before and after the failure occurred, and the failure resulted from significant circumstances beyond your control.

A reasonable cause request is made in writing: a statement of the facts, signed under penalties of perjury, with supporting documents. Fact patterns that have historically carried weight include documented reliance on a professional who gave incorrect advice, serious illness, natural disaster, or prompt correction as soon as the obligation was discovered.

One important caveat: the IRS's popular "first-time abatement" administrative waiver generally does not apply to event-based international information returns like Form 5472. Relief almost always rests on reasonable cause, which is judged on the specific facts — so the quality of the written statement matters.

Step 3: Respond to the Notice Correctly

Read the CP215 notice carefully and check that the facts are right — entity name, EIN, tax year. The notice itself explains how to respond and by when, and those instructions take priority. In general you can dispute the penalty by calling the number on the notice or writing a signed letter explaining why it should be reconsidered, with your reasonable cause statement and evidence attached.

If you have already paid the penalty, the route changes: you may file Form 843, Claim for Refund and Request for Abatement, with a letter explaining why the penalty should not apply, a copy of the notice, and supporting documents.

Avoiding This Entirely Next Year

For calendar-year LLCs, Form 5472 is due April 15. If you need more time, filing Form 7004 before the deadline extends the filing date to October 15 — a free, simple safeguard. And remember that even a quiet year can trigger the obligation: an initial capital contribution from the foreign owner, or the owner paying company expenses personally, counts as a reportable transaction.

The pattern in almost every expensive 5472 case is the same: the form was missed not because it was hard, but because nobody told the owner it existed. Now you know — and if the letter has already arrived, acting quickly is what keeps a $25,000 problem from becoming a $100,000 one.
