Introduction: Pro Forma 1120 for a Foreign-Owned LLC
Many Australian owners assume that a US LLC with no US sales and no profit has no US filing duty. That assumption is wrong often enough to be costly. Money you move into or out of the LLC can trigger an information-reporting obligation, even in a year when the company earned nothing.
This guide covers a US-formed LLC owned by a foreign person or entity, with a focus on the single-member LLC treated as a disregarded entity (DE). It answers five questions:
- Is filing required?
- How does Form 1120 relate to Form 5472?
- What records do you need?
- How do you submit?
- Which separate US and Australian tax issues need professional review?
Key Takeaways
- A pro forma Form 1120 carries Form 5472; it does not make the LLC a taxpayer corporation.
- No revenue does not mean no filing, because owner funding and distributions count.
- Ownership, classification and related-party dealings drive the decision, not profit.
- Get an EIN, keep transaction-level records, and check current IRS instructions each year.
How to Determine Whether a Foreign-Owned LLC Must File
Entity classification comes first
Under the IRS check-the-box rules, a domestic LLC with one owner is disregarded by default. An LLC with two or more members defaults to partnership status. Either can elect corporate treatment on Form 8832, according to the IRS LLC guidance.
This guide's main scenario is a single-member LLC owned directly or indirectly by a foreign person, with no corporate election.
Ownership and related-party status
For disregarded entities (DEs), the test is sole foreign ownership, including qualifying indirect ownership through other disregarded entities or grantor trusts. Australian citizenship alone does not settle the question. Under the IRS definition, a foreign person excludes US citizens and US residents.
Related parties for Form 5472 include:
- A direct or indirect 25% foreign shareholder (for a DE, the foreign owner)
- Entities commonly controlled with the LLC or its owner
- Certain family members and affiliates under the related-party rules (sections 267(b), 707(b)(1) and 482)
Verify each against the current instructions.
Reportable transactions and the no-income misconception
The exception for "no reportable transactions" applies only when Parts IV, V and VI of Form 5472 would be empty. Ownership alone does not decide the question. Review everything the owner and related parties did with the LLC during the year:
- Capital contributions and distributions
- Loans, borrowing and lending
- Formation and state fees paid by the owner
- Expenses the owner paid on the LLC's behalf
- Transfers of money or property
Reimbursements are not named as a category in the rule. Look at the underlying payment, not the label.
A Treasury example makes the point clear. A foreign corporation forms a domestic LLC and contributes assets in year one. In later years it contributes funds, receives a payment, and receives liquidation assets. Each year's transaction is reportable.
Other LLC structures
Do not assume every foreign-owned LLC files the same package.
- Multi-member LLC taxed as a partnership: generally reports on Form 1065.
- LLC electing corporate status: treated as a regular corporation, so a pro forma Form 1120 does not apply.
- Foreign corporation doing business in the US: reports on Form 1120-F.
Owners may also face Form 1040-NR or other returns. Confirm which apply to your facts.
What the Pro Forma Form 1120 and Form 5472 Actually Do
The role of each form
Form 5472 reports certain transactions between the LLC and its related parties. For a foreign-owned DE, the IRS instructions require you to attach Form 5472 to a pro forma Form 1120 by the due date, including extensions.
The package is an information filing, not an ordinary corporate income tax computation. The corporate treatment applies only to section 6038A reporting and recordkeeping. Filing it is not a check-the-box election and does not change the LLC's classification.
Completing the pro forma Form 1120
Complete only the limited fields:
- Write "Foreign-owned U.S. DE" across the top of Form 1120
- Enter the DE's name and address
- Enter the EIN in Item B
- Mark Item E for an initial or final return, and for name or address changes
Do not complete the rest of the corporate return unless the current instructions say so.
Completing Form 5472
The form captures the reporting entity, the foreign owner or related party, transaction categories, amounts and any required statements. Transactions fall into three groups:
- Part IV: monetary transactions
- Part V: DE-specific items such as formation, contributions and distributions
- Part VI: nonmonetary or less-than-full-consideration transactions, which need an attached description with approximate monetary value
File one Form 5472 for each related party with reportable transactions. In Parts IV and VI, "paid" and "received" include accrued amounts.
EIN, tax year, and supporting information
You need an EIN before filing. On Form SS-4, line 7b accepts "foreign" or "N/A" where the responsible party has no SSN or ITIN and is ineligible for one. That is not blanket permission for every foreign owner.
Under the SS-4 instructions, line 9a for a DE should read "Foreign-owned U.S. disregarded entity-Form 5472".
International applicants can also apply by phone on +1 267-941-1099, subject to the IRS eligibility criteria.
Tax year: use the owner's U.S. tax year or, if none, the calendar year. Do not substitute the Australian financial year (July to June) simply because the owner is Australian.
How to Prepare and Submit the Filing Package
Gather information throughout the year
Keep a transaction ledger with date, amount, currency, parties, description, and whether the payer or payee was the owner or another related party. Collect:
- Bank statements
- Formation invoices and state fees
- Owner funding records
- Reimbursement documentation
- Loan agreements
- Distribution records
- Ownership information
Prepare the forms in the correct sequence
- Confirm the LLC's classification.
- Verify the EIN.
- Identify all related parties.
- Reconcile transactions to bank and accounting records.
- Prepare one Form 5472 per related party.
- Complete the limited Form 1120.
- Attach required statements.
State all amounts in US dollars and attach a schedule showing the exchange rates used. The instructions do not specify annual-average or transaction-date rates, so pick a consistent method and document it.
Submit through the correct channel
Under the current instructions, foreign-owned DEs cannot e-file Form 5472. Use fax or mail:
- Fax: 855-887-7737, at 300 DPI or higher
- Mail: Internal Revenue Service, 1973 Rulon White Blvd, M/S 6112, Attn: PIN Unit, Ogden, UT 84201
Confirm these details against the latest instructions before sending. Old articles and third-party software go stale.
Preserve proof and review for procedural errors
Keep a full copy of what you sent and the fax confirmation. Registered mail, or certified mail with a postmarked sender's receipt, can serve as prima facie evidence of delivery under the timely-mailing regulation. That rule covers postal proof, not faxes.
Final checklist:
- EIN correct
- Legal name and address consistent
- "Foreign-owned U.S. DE" marked
- Every related party covered
- Transaction totals reconciled
- Attachments included
- Signature where applicable
- Correct tax year
Deadlines, Extensions, and Penalties
The due date is generally the 15th day of the fourth month after the tax year ends: 15 April for a calendar year.
Extensions: File Form 7004 by the original due date for a six-month extension, ordinarily to 15 October.
Key points when extending:
- Use code 12 and write "Foreign-owned U.S. DE" across the top
- Send the DE's Form 7004 to the dedicated Form 5472 fax or address, not the regular 7004 address
- An extension gives more time to file, not to pay any separate tax due
Penalties: The initial penalty under section 6038A is US$25,000 per related party per tax year. If the failure continues more than 90 days after IRS notice, an additional US$25,000 applies for each 30-day period or fraction. Check current amounts before relying on any figure.
Recent court decisions on Form 5471 penalties (Mukhi and Farhy) do not cancel section 6038A or Form 5472 penalties.
After Filing: Records, Related Obligations, and Missed Years
Recordkeeping and ongoing compliance
Your books should support every reported transaction and reconcile Form 5472 to bank activity, invoices and owner transfers. Book monthly or quarterly and run a year-end related-party review. Reconstructing a year's transactions in April is how errors happen.
Separate US and Australian tax questions
The information filing does not settle income tax. Review these separately:
- ECI and US-source income: ECI is taxed after deductions at graduated rates. Other US-source fixed or determinable income generally faces 30% gross withholding or a lower treaty rate; individuals file Form 1040-NR.
- State and sales tax: state filings and sales tax may apply.
- FBAR: it targets US persons with foreign accounts above US$10,000 in aggregate. A US-formed LLC counts as a US person, so consider its non-US accounts.
- Treaty: the 1982 US-Australia treaty and 2001 protocol turn on permanent establishment and attributable profits.
On the Australian side, residents generally declare foreign income to the ATO. In ATO ID 2010/77, a single-member US LLC with no corporate election, disregarded in the US, was treated as a foreign hybrid partnership under Division 830.
That 2010 example is not published advice, and US disregarded status does not automatically mean Australian transparency. Coordinate with an Australian tax adviser on residency, entity treatment, treaty positions and reporting.
Missed filings and professional support
If you find missed years, gather prior records and work out which returns were required. The IRS delinquent international information return procedures cover taxpayers not under examination and not yet contacted.
A reasonable-cause statement may accompany the return, but relief is not automatic, and IRM 20.1.9 recommends filing all delinquent returns first.
VJM Global provides cross-border tax compliance, accounting and financial support for international businesses, including Australian ones, and can help organise records and evaluate filing requirements. It does not replace tailored tax advice, and no outcome is promised.
Seek a qualified professional when ownership is indirect, multiple related parties are involved, income connects to US activity, or earlier filings were missed.
Frequently Asked Questions
Who must file Form 1118?
Form 1118 is generally for corporations computing a foreign tax credit. It is not part of the Form 5472 and pro forma 1120 package for a foreign-owned DE. Check current instructions for exceptions.
Does a foreign-owned LLC with no income still need to file a pro forma Form 1120?
Possibly. Owner funding, formation payments, expenses paid by the owner or distributions may be reportable even with zero income.
Is Form 5472 the same as Form 1120?
No. Form 5472 is a related-party information return. For a foreign-owned DE, the pro forma Form 1120 is the cover filing that carries it.
What transactions must be reported on Form 5472?
Common items include capital contributions, distributions, loans, formation costs and other transfers with related parties. Check the current IRS definitions for each Part.
Can a foreign-owned multi-member LLC use the same filing process?
Generally no. It defaults to partnership treatment and reports on Form 1065, or is a corporation if it elected that status. Withholding and owner-level duties may differ.
What should I do if my foreign-owned LLC missed a prior-year filing?
Review classification and past transactions, gather evidence, and get professional advice on delinquent-filing and penalty-relief procedures before submitting anything.
