Form 5472: Why Foreign-Owned U.S. Companies Face a $25,000 Trap
If a non-U.S. person owns your U.S. LLC or corporation, you almost certainly have a filing obligation most software never mentions — and the penalty for missing it starts at $25,000 per year.
Foreign founders love the U.S. LLC: it is fast, cheap, and credible. What few realize is that a single-member LLC owned by a non-U.S. person is treated as a reporting corporation for one specific form — and skipping it triggers one of the harshest automatic penalties in the code.
Who has to file
Form 5472 applies to:
- A U.S. corporation that is at least 25% foreign-owned, or
- A foreign-owned U.S. disregarded entity — most commonly a single-member LLC with a non-U.S. owner.
The second case surprises people. A single-member LLC normally files nothing of its own. But once the owner is foreign, the LLC must obtain an EIN, file a pro-forma Form 1120, and attach Form 5472 — even if it had zero revenue.
The reportable transaction. Form 5472 reports "reportable transactions" with related parties — capital contributions, loans, payments, even money you moved from your own foreign account into the LLC counts. Many owners assume "no sales = no filing." That is incorrect.
The $25,000 penalty
The failure-to-file penalty is $25,000 per form, per year, and it is essentially automatic — assessed first, argued later. It applies whether or not any tax was due, and it stacks for every year a required form was missed.
| The numbers | |
|---|---|
| $25,000 | per missed form, per year |
| 25% | foreign ownership that triggers it (corporations) |
| $0 | income still required to file |
Why software misses it
Consumer and even many SMB tax tools simply do not generate a pro-forma 1120 with a 5472 attachment for a zero-income disregarded entity. The obligation falls through the cracks until a founder gets a notice — often years and several penalties later.
If you are already behind
Late 5472s can frequently be addressed through reasonable-cause relief or established correction procedures, especially when there was no tax due and the omission was inadvertent. The key is to act before the IRS contacts you. A CPA who files these regularly can usually map your exposure and a fix in a single call.

The short version
- Form 5472 reports transactions between a U.S. entity and its foreign owner or related parties.
- Foreign-owned single-member LLCs must file even with no income.
- The penalty for failing to file is $25,000 per form, per year — automatic.
- Almost no consumer tax software handles this correctly.
