Who this is for: This guide is for US citizens and green card holders who own shares in, or are officers or directors of, a French company such as an SAS or SARL. It explains the Form 5471 reporting obligation and why it is one you cannot afford to miss.
If you are a US person and you hold an interest in a French company, the US may require you to report that company on Form 5471, filed with your personal US tax return. It is an information return, not a tax in itself, but the penalties for not filing are severe and the rules are easy to trip over, especially for founders and employees who received shares without realising what followed.
What Form 5471 is
Form 5471 is the IRS information return for US persons who are officers, directors or shareholders of certain foreign corporations. It reports the company’s ownership, its financial results and, in some cases, income that the US taxes currently even if nothing is distributed. Which parts you complete depends on which category of filer you fall into, and a single person can fall into more than one.
The categories decide how much work it is
Form 5471 is not one form so much as five overlapping ones. Your category of filer determines which schedules you complete, and the difference between the lightest and heaviest category is substantial.
Broadly, you are filing because | Typical trigger |
You are an officer or director and a US person crossed an ownership threshold | Someone else’s share purchase pulls you in |
You acquired, disposed of, or changed a 10% or greater interest | Founding, a funding round, a share transfer or an exit |
You control the foreign corporation | More than 50% of vote or value |
You are a US shareholder of a controlled foreign corporation | The company is majority US-owned and you hold at least 10% |
A related-party or reorganisation situation applies | Group restructuring involving the French entity |
A single person can fall into more than one category in the same year, and the categories are cumulative rather than alternatives.
When a French company triggers it
Two questions matter. First, is the French entity treated as a corporation for US tax purposes? This is the key question, and it depends on the entity’s US tax classification and the specific facts, not on its French legal form alone. French forms are treated differently. The société anonyme (SA) appears on the IRS list of entities that are always treated as corporations, with no election available. The SAS and SARL are not on that list: they are ‘eligible entities’ that can either fall under a default treatment or elect their US classification through a check-the-box election — to be treated as a corporation, a partnership, or a disregarded entity. Form 5471 is only relevant where the entity is treated as a foreign corporation for US tax purposes. Second, how much do you own and in what capacity? Common triggers include:
- Acquiring or disposing of a 10% or greater interest in the foreign corporation.
- Being a US shareholder of a Controlled Foreign Corporation (CFC), broadly a foreign corporation more than 50% owned by US shareholders.
- Being a US officer or director of a foreign corporation in which a US person acquires a significant interest.
- Being a US person who controls the foreign corporation.
One point is widely misunderstood. Because every member of an SAS or SARL has limited liability, the default classification for US purposes is a corporation. Absent a deliberate election, a US owner of an SAS or SARL is therefore usually in Form 5471 territory rather than outside it. Whether that default has been changed by an election is a fact-specific question that should be checked rather than assumed.
Why a CFC matters: Subpart F and GILTI
If your French company is a Controlled Foreign Corporation, US shareholders can be taxed on some of its earnings currently, before any dividend is paid, under the Subpart F and GILTI rules. This is a substantive tax exposure layered on top of the reporting, and it is one of the main reasons US ownership of a profitable French company needs planning rather than an after-the-fact filing.
The penalties are the reason to take it seriously
The penalty for failing to file a required Form 5471 starts at $10,000 per form, per year, with additional continuation penalties that can add up to a further $50,000, and it can also reduce foreign tax credits. Critically, a missing Form 5471 can keep the statute of limitations open on your entire tax return, not just the form, leaving years exposed to IRS review. Few information returns carry this combination of a fixed penalty and an open-ended statute, which is why it is worth getting right.
Exposure | What it means |
$10,000 per form, per year | Applied for each annual accounting period the form was missed |
Up to $50,000 in continuation penalties | Accrues after IRS notice if the form is still not filed |
Reduction of foreign tax credits | A further 10% reduction can apply, compounding the cost |
Statute of limitations stays open | Under IRC 6501(c)(8) the whole return can remain open, not just the form |
The last line is the one that changes the risk profile. A return with a missing Form 5471 does not become final in the usual three years, so a filing gap from years ago can still be examined today.
What to do
- Map your ownership before year-end. Know your percentage, your capacity (shareholder, officer, director) and whether the company is a CFC.
- Confirm the US classification of your SAS or SARL, including any check-the-box position.
- Model Subpart F and GILTI if the company is profitable and US-controlled.
- If you are already behind, ask about the delinquent international information return procedures and, where relevant, the Streamlined route, rather than filing blind.
