FREQUENTLY ASKED QUESTIONS (FAQ)
General Filing Requirements
-
What are Forms 1120 and 5472?
Form 1120 is the US Corporation Income Tax Return. Form 5472 is an informational return used to report transactions between a US reporting corporation and a foreign related party. -
Who is required to file Form 5472?
Filing is mandatory for: - Foreign-owned US disregarded entities (DEs), such as 100% foreign-owned single-member LLCs.
- US Corporations that are at least 25% foreign-owned.
-
Do I have to file if my company had no income?
Yes. Foreign-owned single-member LLCs must file even if they had no US-source income, no US clients, or no business activity during the year, provided there was at least one "reportable transaction".
The "Pro Forma" 1120 vs. Full 1120
-
How do these forms work together for a single-member LLC?
Foreign-owned single-member LLCs (disregarded entities) do not file a full corporate return. Instead, they file a pro forma Form 1120, which acts as a cover sheet for the required Form 5472. -
What information goes on a pro forma Form 1120?
You typically only complete the name, address, and items B and E on the first page, and write "Foreign-owned U.S. DE" across the top. -
When does a company file a full Form 1120?
A full Form 1120 is required for US C-Corporations. If that corporation is at least 25% foreign-owned, Form 5472 must be attached to the complete corporate tax return.
Reportable Transactions
-
What counts as a "reportable transaction"?
Common reportable transactions include: - Initial capital contributions or funding used to form the LLC.
- Loans or cash "top-ups" from the foreign owner.
- Distributions of money or property back to the owner.
- Paying US business expenses from an overseas personal account.
-
Do I need multiple Form 5472s?
Yes, a separate Form 5472 must be filed for each foreign related party that had reportable transactions with the US entity.
Exceptions
There are specific exceptions to the requirement for filing Form 5472 and the associated Form 1120. However, the IRS Instructions for Form 5472 apply these exceptions differently depending on whether the entity is a standard corporation or a Foreign-Owned U.S. Disregarded Entity (DE) like a single-member LLC.
1. The "No Reportable Transactions" Exception
The primary exception for all reporting entities is having no reportable transactions during the tax year.
- General Rule: If a reporting corporation (including a foreign-owned DE) has no transactions with related parties of the types listed in Parts IV, V, or VI of the form, it is generally not required to file Form 5472.
- Caveat for LLCs: For a foreign-owned DE, "reportable transactions" are defined broadly in Part V. This includes simple actions like the owner paying the LLC's registration fees or making a small capital contribution. If the LLC was completely dormant with zero activity, it is exempt.
2. Specific Corporate and Other Exceptions
Additional exceptions exist, particularly for corporations, as detailed in the IRS Instructions for Form 5472:
- Form 5471 Filing: Exemption may apply if a U.S. person controlling the foreign corporation files Form 5471.
- Foreign Sales Corporations: Entities filing Form 1120-FSC are generally exempt.
- Non-U.S. Transaction Exception: Generally applicable when neither party is a U.S. person and transactions do not produce U.S.-source income, according to the IRS.
-
Other Exemptions: Certain foreign entities with treaty-based return positions (Form 8833), Section 883 exemptions, or those in a consolidated return may be exempt.
Deadlines and Submission
-
What is the filing deadline for 2026?
The standard deadline for calendar-year entities is April 15, 2026. -
Can I get an extension?
Yes, you can request an automatic six-month extension until October 15, 2026, by filing Form 7004 by the original April 15 deadline. -
Can I e-file these forms?
Generally, no for disregarded entities. Foreign-owned US DEs must typically submit the pro forma 1120 and Form 5472 by mail or fax to a specific IRS address.
Penalties for Non-Compliance
-
What is the penalty for failing to file?
The initial penalty for failing to timely file a complete and accurate Form 5472 is $25,000 per form. -
Are there additional penalties?
If the IRS notifies you of a failure to file and you do not comply within 90 days, an additional $25,000 penalty may be assessed for each 30-day period (or fraction thereof) that the failure continues. -
Does filing Form 5472 affect the Statute of Limitations?
Yes. Failing to file Form 5472 may keep the statute of limitations open indefinitely for the entire tax return, allowing the IRS to audit that year at any time in the future.
