Form 5472 filing requirements apply to any non-US resident who owns a US LLC or corporation, and it is one of the most commonly missed obligations in the US tax code. The penalty for getting it wrong starts at $25,000 per form per year, and it applies even if your business had no income or activity during the year.
Form 5472 is not a tax payment form. It is an information reporting form. The IRS uses it to track transactions between foreign owners and their US entities. Understanding who needs to file, what needs to be reported, and when it is due is essential for any foreign owner of a US business.
- US Corporation (25% or more foreign owned): Required if reportable transactions exist. Filed attached to Form 1120.
- Foreign Corporation (US effectively connected income and related party transactions): Required if reportable transactions exist. Filed attached to Form 1120-F.
1. Foreign Owned Single Member LLCs
A single member LLC owned by a non-US resident is treated as a disregarded entity for US tax purposes. It is required to file Form 5472 along with a pro forma Form 1120 every year, regardless of whether the LLC had any income or activity.

25% Foreign Owned US Corporations
Any US corporation that is at least 25% owned by a foreign person, directly or indirectly, is required to file Form 5472 for each related party with whom reportable transactions occurred during the year.
Foreign Corporations with US Effectively Connected Income
Foreign corporations conducting a US trade or business with effectively connected income are required to file Form 5472 only if they had reportable transactions with related parties, including 25% foreign shareholders, foreign affiliates, or US related corporations.
Multiple Foreign Owners
If a US corporation has more than one foreign shareholder, one Form 5472 is required per related party with reportable transactions. If multiple 25% foreign owners exist but only one had transactions with the US entity, only one Form 5472 is required for that related party.
2. What Counts as a Reportable Transaction for Form 5472
The core purpose of Form 5472 is to report transactions between the US entity and its foreign owner or related parties. The definition of a reportable transaction is broader than most foreign owners expect.
- Monetary Transactions: Any transfer of money between the US entity and the foreign owner is a reportable transaction. This includes capital contributions made by the owner to the LLC, distributions paid out to the owner, and any loans between the two.
- Non-Monetary Transactions: Transfers of property, including equipment, intellectual property, and real estate, between the US entity and the foreign owner are also reportable, even if no money changed hands.
- Services: If the foreign owner provides services to the US entity, or the US entity provides services to the foreign owner, these transactions need to be reported.
- Rents and Royalties: Any rent or royalty payments between the US entity and the foreign owner or related parties are reportable transactions.
- Zero Transaction Years: If no reportable transactions occurred during the year, a filing may not technically be required. However, because capital contributions, distributions, and other common activities are treated as reportable transactions, most foreign owned entities still have a filing obligation in practice. If you are unsure whether your activity triggers the requirement, that is a question worth discussing with a qualified tax professional before assuming no filing is needed.
3. The Pro Forma Form 1120 and How It Works
Foreign owned single member LLCs are required to file Form 5472 attached to a pro forma Form 1120. This is one of the most misunderstood aspects of the filing requirement.
A pro forma Form 1120 is not a full corporate tax return. It is a simplified version that serves as a cover sheet for Form 5472. It includes basic identifying information about the LLC but does not require the LLC to calculate or pay corporate income tax.
- Why It Is Required: Because a single member LLC is a disregarded entity, it does not file its own tax return under normal circumstances. The pro forma Form 1120 is the mechanism the IRS uses to receive the Form 5472 for disregarded entities.
- What It Includes: The pro forma Form 1120 includes identifying information about the LLC and the foreign owner. It does not include income, deductions, or tax calculations.
- Filing Address: The pro forma Form 1120 with the attached Form 5472 is filed at the IRS address designated for Form 1120 filings. For foreign owned disregarded entities, this is commonly the Austin, TX address. However, the correct address can vary depending on how the return is submitted and whether a payment is enclosed. Always confirm the current address in the IRS instructions before filing.
- Electronic Filing: Form 5472 can be electronically filed through an IRS-approved Modernized e-File provider when attached to a standard Form 1120 or Form 1120-F. In most cases, foreign owned disregarded entities filing via a pro forma Form 1120 must submit by mail or fax, as this filing type is not fully supported by standard e-file systems. Ensure that you are aware of the method applicable to your entity type, and work with a CPA or tax professional who is familiar with these requirements.
4. Form 5472 Filing Deadlines
The filing deadline for Form 5472 depends on your entity type. It is also worth noting that the filing obligation begins in the same tax year the entity was formed. If your LLC was formed in October, you are already required to file for that year by the following April 15.
- Single Member LLCs: For calendar year entities, the pro forma Form 1120 with the attached Form 5472 is due by April 15 for the prior calendar year. A 6 month extension is available by filing Form 7004, which extends the deadline to October 15.
- US Corporations: For calendar year corporations that file Form 1120, the Form 5472 is attached to the corporate return and follows the same deadline, which is April 15. A 6 month extension is also available.
- Important Note: The extension to file is not an extension to pay. If any taxes are owed, they are due by the original deadline regardless of whether an extension has been filed.
5. Form 5472 Penalties for Non-Compliance
The penalty for failing to file Form 5472, or for filing an incomplete or inaccurate Form 5472, is $25,000 per form per year. This is one of the highest information reporting penalties in the US tax code.
- Per Form Penalty: The $25,000 penalty applies per Form 5472, not per entity. If a US corporation has three foreign shareholders who each meet the 25% threshold and the corporation fails to file, the penalty exposure is $75,000.
- Continuing Penalty: If the failure to file continues beyond 90 days after the IRS notifies the entity of the requirement, an additional $25,000 penalty applies for each 30 day period the filing remains outstanding after that point. There is no statutory maximum, meaning penalties can accumulate indefinitely.
- No Income Is Not a Defense: The penalty applies regardless of whether the entity had any income or activity during the year. The filing obligation exists from the moment the entity is formed and a foreign owner is involved.
- Reasonable Cause Exception: The IRS does provide relief from the penalty in cases where the failure to file was due to reasonable cause and not willful neglect. However, this is a high bar to meet and is not guaranteed.
- Statute of Limitations: Failing to file Form 5472 keeps the statute of limitations open indefinitely with respect to items related to the required reporting. The IRS can audit and assess penalties on those items at any point in the future with no time restriction. Filing on time, even with zero transactions to report, is the only way to close that window.
6. Getting an EIN as a Foreign Owner
Before you can file Form 5472, your LLC or corporation needs an Employer Identification Number. Getting an EIN as a non-US resident requires a different process than the standard online application, and the method available to you depends on your specific situation.
The options available to foreign owners include applying by fax, by phone through the IRS international line, or by mail. Processing times vary significantly across these methods, and delays in obtaining an EIN can affect your ability to meet your filing deadlines. Working with a tax professional who is familiar with the process can help avoid those delays.
- ITINs: Some foreign owners also need an Individual Taxpayer Identification Number in addition to an EIN. If you have US-sourced income that is subject to withholding, you may need an ITIN separately from your EIN. These are two different numbers that serve different purposes. Ensure that you are clear on which one applies to your situation before you begin filing.
7. Other US Tax Obligations for Foreign Owners of US Entities
Form 5472 is not the only filing requirement that may apply to foreign owners of US entities. Depending on your situation, there may be additional obligations.
- FBAR: If you have a financial interest in or signature authority over foreign bank accounts with a combined balance that exceeded $10,000 at any point during the year, you may be required to file an FBAR, which is a Report of Foreign Bank and Financial Accounts, with FinCEN.
- FATCA: Form 8938 generally applies to US taxpayers with foreign financial assets and may not apply to non-US residents unless they meet US tax residency rules. If you are unsure whether this applies to your situation, it is worth confirming with a tax professional.
- State Filing Requirements: Forming an LLC or corporation at the state level creates state level compliance obligations as well, including annual reports and state income tax filings in states where the entity has nexus. For a full breakdown of what ongoing compliance looks like once your entity is active, read here: Compliance 101: Keeping Your Business in Good Standing
- Tax Treaties: The US has tax treaties with many countries that can affect how your US sourced income is taxed. Ensure that you are aware of whether a treaty applies to your situation and how it affects your filing obligations.
