Form 5472: Reporting Requirements for Foreign-Owned US Businesses

Who Must File Form 5472?

Two categories of entities trigger the Form 5472 filing requirement. The first is US corporations where a single foreign person owns 25% or more of the stock, directly or indirectly. A single foreign shareholder at that threshold is enough to require filing, and the requirement applies regardless of whether the corporation is profitable or active.

The second category, added by regulation in 2017, is foreign-owned single-member LLCs that are treated as disregarded entities for US tax purposes. This category catches a significant number of foreign entrepreneurs and international founders who form US LLCs to access US markets or banking without realizing they’ve created an annual reporting obligation. Foreign-owned multi-member LLCs are treated as partnerships and file Form 1065 instead.

What Are Reportable Transactions?

Form 5472 requires disclosure of all reportable transactions between the US entity and its 25% foreign owner or any related foreign party. The definition of reportable transaction is broad. It covers sales of goods and property, rentals, royalties, loans and interest payments, services, and the use of property.

For foreign-owned disregarded LLCs, the scope is even broader. Any monetary transaction between the LLC and its foreign owner is reportable, including capital contributions made by the owner, distributions taken by the owner, and any other cash movement between them. A foreign entrepreneur who deposits startup funds into their US LLC's bank account, pays business expenses from it, and withdraws profits has created reportable transactions at each of those steps. The routine movement of money between owner and entity that most single-member LLC owners never think about becomes a formal reporting obligation under Form 5472.

Form 5472 for Foreign-Owned Disregarded LLCs: What's Different

The 2017 regulatory change that brought foreign-owned disregarded LLCs into the Form 5472 regime also imposed several related requirements. These LLCs must obtain an EIN by filing Form SS-4. They must maintain a US registered agent. They must keep books and records in the United States or make them available to the IRS upon request.

Because a disregarded LLC is otherwise invisible to the US tax system, the LLC must also file a pro forma Form 1120 solely for the purpose of attaching Form 5472. The pro forma return is not a real corporate return. The LLC doesn't owe corporate tax. The filing exists purely as a vehicle for submitting Form 5472, and it follows the corporate return deadline rather than the individual return deadline.

Form 5472 Penalties

The base penalty for failure to file Form 5472, or for filing a form that is incomplete or inaccurate, is $25,000 per form per tax year. If noncompliance continues after the IRS issues a notice requiring the filing, an additional $25,000 penalty applies for each 90-day period the violation continues. A business with multiple foreign owners above the 25% threshold, or with reportable transactions across multiple related entities, may face multiple forms and multiple penalty exposures simultaneously.

These penalties are assessed on information returns, not on tax owed. A business that had no taxable income and no tax liability still faces the full $25,000 penalty for a missing Form 5472.

Form 5472 Filing Deadline

The deadline depends on the entity type. For foreign-owned disregarded LLCs, the pro forma Form 1120 and attached Form 5472 are due April 15, with an extension available to October 15. For C-corporations, the due date is April 15, extendable to October 15. For S-corporations, the return and attached Form 5472 are due March 15, with an extension to September 15.

How Slash Supports Foreign-Owned US Businesses

Foreign-owned US businesses need a US business bank account to operate, and for entities subject to Form 5472, the transactions flowing through that account are often the primary source of reportable transaction data. Capital contributions, owner distributions, intercompany loans, and service payments between the US entity and its foreign owner all need to be clearly documented, accurately totaled, and supported by transaction records if the filing is ever examined.

Slash's business banking gives foreign-owned LLCs and US corporations with foreign investors an organized record of all transactions between the entity and related parties, with the documentation clarity that Form 5472 reporting and audit defense require.
