Federal reporting mandates under IRC § 6038A
Foreign founders often misunderstand the tax status of a US single-member LLC. While the Internal Revenue Service treats a single-member LLC owned by a non-resident alien as a “disregarded entity” for federal income tax purposes (meaning entity profits flow through directly to the owner without corporate income tax), federal law imposes rigorous informational disclosure requirements. Under Internal Revenue Code § 6038A and Treasury Regulation § 1.6038A-2, foreign-owned US disregarded entities are treated as domestic corporations solely for the purpose of filing annual informational returns.
Anatomy of Form 5472 and Pro-Forma Form 1120
Compliance requires submitting two interlinked federal forms: IRS Form 5472 (Information Return of a 25% Foreign-Owned U.S. Corporation) attached to a “pro-forma” IRS Form 1120 (U.S. Corporation Income Tax Return). Because the LLC is a disregarded entity, Form 1120 is filed with only basic identifying details (entity name, address, Employer Identification Number, and formation date), with all income and deduction lines left blank except for check-box declarations.
| Form Section | Reported Information | Statutory Requirement | Common Founder Pitfall |
|---|---|---|---|
| Form 1120 Header | LLC Name, EIN, Address, Formation Date | Treas. Reg. § 1.6038A-1 | Calculating standard corporate tax instead of submitting a pro-forma zero return. |
| Form 5472 Part I | Reporting Entity details and total assets | IRC § 6038A(b)(1) | Failing to provide year-end total asset valuation for the LLC. |
| Form 5472 Part II | 25% Foreign Shareholder identifying information | IRC § 6038A(b)(2) | Omitting the owner’s foreign tax identification number (FTIN) or passport details. |
| Form 5472 Part IV | Reportable monetary and non-monetary transactions | Treas. Reg. § 1.6038A-2 | Omitting capital contributions, owner distributions, or formation fee reimbursements. |
Defining reportable transactions in Part IV
A reportable transaction includes virtually any financial movement between the foreign owner (or any related foreign entity) and the US LLC during the calendar year. This includes initial capital contributions transferred to open the company bank account, distributions of profit paid out to the founder’s personal account, loans between the member and the LLC, and reimbursement of initial formation costs. Every dollar moved into or out of the LLC must be accounted for and reconciled against bank records.
Filing mechanics and penalty relief procedures
The deadline to file Form 5472 and pro-forma Form 1120 is April 15 following the close of the tax calendar year (or October 15 if an automated extension is requested via IRS Form 7004 before the April deadline). Crucially, the IRS generally does not allow consumer tax software to e-file pro-forma Form 1120 returns for disregarded entities; submissions must be sent via certified fax or registered postal mail to the Internal Revenue Service Center in Ogden, Utah. Founders who prefer hands-off compliance often coordinate these mandatory annual filings through corporate filing specialists such as Zenind.
Under IRC § 6038A(d), the statutory penalty for failing to file Form 5472, late filing, or filing an incomplete return is $25,000 per violation per year. If the IRS issues a failure-to-file notice and the non-compliance continues for more than 90 days, an additional $25,000 penalty applies for each subsequent 30-day period. Penalty abatement requires demonstrating reasonable cause under strict IRS procedural standards.

Can Form 5472 be e-filed online without a US tax software account?
Pro-forma Form 1120 with Form 5472 for disregarded entities generally cannot be e-filed through standard consumer tax portals; it must be transmitted to the IRS Internal Revenue Service Center via certified fax or mail.
Does filing Form 5472 mean I have to pay US income tax?
