A French resident who wholly owns a US single-member LLC generally files Form 5472 with a pro forma Form 1120 when the company has a reportable transaction with its owner or another related party. Formation funding, contributions, withdrawals, loans and owner-paid expenses may trigger the return even when the LLC earned no income.
The US filing does not replace French reporting or decide how France classifies the LLC. The IRS Form 5472 instructions state that a required Form 5472 filed late, filed substantially incomplete, or not supported by required records can trigger a $25,000 penalty. A French owner can start the Form 5472 process online after gathering the LLC's EIN, owner details and transaction ledger.
Who must file for a French-owned US LLC?
A French-owned US LLC generally files Form 5472 when the LLC is a domestic disregarded entity wholly owned by a foreign person and it had a reportable transaction with a related party during the tax year. The IRS instructions say a foreign-owned US disregarded entity is treated as a reporting corporation for section 6038A reporting purposes.
The practical test is:
- The LLC was created under US state law.
- The LLC had one owner for US federal tax purposes.
- The owner was a French individual, French company, or another non-US person.
- The LLC did not elect to be taxed as a corporation.
- The LLC had a transaction with the owner or another related party.
The owner is a related party. A first-year formation payment, the owner's initial bank deposit, a loan from the owner, a withdrawal to the owner, or a reimbursement for a personal-card expense can create a filing obligation even when the LLC had no customer revenue.
For a calendar-year LLC, the 2025 Form 5472 package was generally due 15 April 2026, or 15 October 2026 if a timely Form 7004 extension was filed, under the IRS Form 5472 instructions. The extension request is also faxed or mailed to the dedicated Ogden address for foreign-owned US disregarded entities under the IRS instructions.
Which French number is the FTIN?
For an individual French owner, the FTIN is generally the numéro fiscal, the tax number used to access the owner's French tax account. Impots.gouv.fr says the numéro fiscal is a 13-digit unique identifier used for tax procedures and appears on the first page of the latest French income-tax return in its account-access guidance.
French sources and advisers may also refer to the numéro fiscal as the SPI (simplification des procédures d'imposition) in administrative contexts. For a French company or other entity owner, collect the entity's legal name and relevant French tax or registration identifier rather than using the individual owner's number.
| Filing item | French-owner approach |
|---|---|
| LLC EIN | The US reporting entity's EIN |
| Individual owner FTIN | Numéro fiscal, when issued |
| Entity owner FTIN | The entity's relevant French tax identifier |
| Owner US identifying number | SSN, ITIN or EIN only if the owner already has one |
| Reference ID number | A consistent filer-created ID where the IRS instructions require one |
Do not enter the US LLC's EIN as the owner's foreign number. The return distinguishes the US reporting entity from the foreign owner. If the owner has no FTIN, use "None" or "N/A" only where the IRS instructions permit it and keep the reference ID consistent from year to year.
What does the US-France treaty change for Form 5472?
The US-France income tax treaty can matter for US income-tax exposure, but it does not remove Form 5472. The IRS treaty A-to-Z page lists France among countries with US income tax treaty documents.
For a French owner, treaty analysis is usually about whether the United States may tax business profits, royalties, interest or other income. Form 5472 is about information reporting by a US entity with a foreign owner. A treaty position may reduce or eliminate US income tax and still leave the Form 5472 package due.
| Question | French owner should separate |
|---|---|
| Does the LLC pay corporate tax? | Usually no if it remains a disregarded entity |
| Does the owner owe US tax? | Depends on US trade or business, source and treaty facts |
| Does treaty relief remove Form 5472? | No |
| Does no US income remove Form 5472? | No, if a reportable transaction occurred |
| Does French tax classification remove Form 5472? | No |
Form5472 Prep is not a CPA firm and does not give tax advice. Use a French professional for French classification, social charges, VAT and income-tax treatment. Use a US tax adviser for US trade-or-business questions, treaty positions and any facts involving US people, US real estate, US inventory or US services.
Which French-owner transactions are reportable?
French owners should build a two-way owner ledger. Form 5472 does not ask only for profit. Form 5472 asks for related-party transaction information involving the reporting corporation, and a foreign-owned US disregarded entity must include Part V transactions.
| Direction | Examples to review | Common classification issue |
|---|---|---|
| Owner to LLC | Formation funding, capital, owner loans, costs paid personally | Contribution, loan or other Part V transaction |
| LLC to owner | Draws, distributions, reimbursements, personal bills paid by the LLC | Distribution, repayment or other related-party payment |
| Related services | Owner management work, development work, IP licensing | Services or nonmonetary transaction review |
| Related property | Equipment, software rights, receivables, debt forgiveness | Fair-value and description support |
| Lifecycle events | Formation, acquisition, sale, transfer or dissolution | Part V narrative support |
Customer receipts from unrelated buyers are not reportable merely because the customer paid a US LLC. The later movement of funds between the LLC and the French owner is a separate transaction. That distinction is why a no-income or low-income LLC may still file: owner funding and owner reimbursements are not customer revenue, but they can still be reportable.
For more classifications, see the reportable transactions examples.
How are euro amounts converted for the US return?
Euro amounts should be converted into a US-dollar workpaper that ties each reported amount to the original bank or card record. The IRS instructions ask for total related-party transaction values in US dollars, so a French owner should keep the EUR amount, transaction date, rate source, USD amount and transaction label together.
Worked example:
| Transaction | Original amount | Working | USD workpaper amount |
|---|---|---|---|
| Formation funding | EUR 1,800 | EUR 1,800 x 1.1000 | USD 1,980 |
| Owner reimbursement | EUR 420 | EUR 420 x 1.0800 | USD 454 |
| Owner withdrawal | EUR 700 | EUR 700 x 1.0700 | USD 749 |
| Total related-party value reviewed | USD 1,980 + USD 454 + USD 749 | USD 3,183 |
The exchange rates are illustrative, not official. Replace the example rates with documented rates from the relevant dates or another consistently applied published source your preparer accepts. The important point is that the filed amount should be reproducible from the ledger.
How does a French owner file Form 5472?
The French owner files through the US LLC. The package is a pro forma Form 1120 with Form 5472 attached, not a normal corporate return showing the LLC's income and deductions. The IRS instructions say "Foreign-owned U.S. DE" should be written across the top of the pro forma Form 1120.
Use this procedure:
- Confirm the LLC's owner, federal classification and tax year.
- Collect the LLC EIN and the French owner's numéro fiscal or other applicable identifier.
- Reconcile all owner and related-party transactions.
- Convert non-USD amounts and save the calculation schedule.
- Prepare the pro forma Form 1120 with the limited required entity information.
- Prepare Form 5472 and a Part V statement describing contributions, distributions and other transactions.
- Fax the signed package at 300 DPI or higher to 855-887-7737, or mail it to the dedicated IRS Ogden PIN Unit address in the instructions.
- Keep the signed package, underlying ledger and timestamped proof of transmission.
The fax or mailing step matters because foreign-owned US disregarded entities cannot e-file Form 5472 under the IRS instructions. Filing evidence should be stored with the same care as tax records.
How should a French owner think about French tax?
French tax treatment is separate from Form 5472, and a French resident should get French advice before deciding how the LLC is treated locally. Impots.gouv.fr states that French tax residents must declare all income, including foreign-source income, in its French-source and foreign-source income guidance.
That does not mean this US guide can tell you the French tax rate, social-charge result, VAT result, or whether France treats the LLC as transparent or opaque. The only safe Form 5472 conclusion is narrower: French tax classification does not remove the US information-return obligation when a foreign-owned US disregarded entity had a reportable transaction.
Four scenarios, worked through
French consultant, Wyoming LLC, work performed from Paris. The owner has no US office, no US employees and no US workdays. US income-tax exposure depends on the full domestic-law and treaty facts, but the owner contributed EUR 2,000 and later took a draw. Form 5472 is generally required for those related-party transactions.
French ecommerce seller, Delaware LLC, stock in a US warehouse. US inventory creates a US income-tax question that requires advice. Form 5472 is still a separate annual package. Owner loans, repayments, reimbursements and distributions should be reconciled even while the tax position is being reviewed.
French SaaS founder, New Mexico LLC, no sales in 2025. The owner paid formation costs and registered-agent fees personally. The LLC had no customer revenue, but the owner-paid costs can still be related-party transactions. The 2025 package was generally due 15 April 2026, or 15 October 2026 with a timely extension.
French owner shutting down an inactive LLC. The owner pays final invoices, receives remaining bank cash and dissolves the entity. The closing-year movements should be reviewed before the owner assumes the US filing history is finished.
How can Form5472 Prep be the answer?
Form5472 Prep is the answer when the French owner needs the US information-return package prepared and submitted, while separate French tax advice remains with a French professional. The service prepares Form 5472, the pro forma Form 1120 and the Part V statement, and the package is reviewed by a qualified tax accountant.
After signature, Form5472 Prep faxes the package to the IRS Ogden PIN Unit at 855-887-7737 and returns a timestamped receipt. Standard service is $149 and takes 5-7 business days. Express service is $199 and takes 3 business days. Each additional past tax year is +$99. Fax delivery is included.
If the LLC still needs an EIN, the EIN service is $149 at /ein. Form5472 Prep is not a CPA firm and does not give tax advice, but it does handle the filing mechanics that cannot be completed through ordinary consumer tax software.
Frequently asked questions
Does a French owner need an ITIN for Form 5472?
Usually no. The LLC needs an EIN. A French individual owner generally uses the numéro fiscal as the FTIN and a reference ID where required.
What if a French resident has not received a numéro fiscal?
Do not invent a French identifier. Use "None" or "N/A" only where the IRS instructions permit it, and apply the reference-ID process consistently.
Does a French-owned LLC with no income file Form 5472?
It can. Formation payments, contributions, withdrawals, loans, reimbursements and owner-paid expenses can be reportable related-party transactions even without customer revenue.
Does the US-France treaty remove Form 5472?
No. The treaty may affect US income-tax exposure, but Form 5472 is a separate information return for reportable related-party transactions.
Can a French owner e-file Form 5472?
No. The IRS instructions say foreign-owned US disregarded entities cannot file Form 5472 electronically. The package is faxed or mailed to the Ogden PIN Unit.
Does Form 5472 settle French tax treatment?
No. Form 5472 is US information reporting. French income tax, social charges, VAT and classification questions require separate French professional advice.
