1. Why Foreign-Owned Single-Member LLCs Must File Form 5472
Under US Treasury Regulations updated in 2017 (T.D. 9796), foreign-owned single-member LLCs (Disregarded Entities) are treated as domestic US corporations solely for the purpose of Section 6038A information reporting.
This mandatory reporting rule applies to any US LLC where a foreign non-resident alien person or entity directly or indirectly owns 25% or more of the company's equity. Crucially, the IRS requires Form 5472 filing even if your LLC generated $0 in revenue or conducted zero commercial activity during the tax year.
2. What Constitutes a Reportable Transaction Under Part IV?
Under Part IV of Form 5472, a reportable transaction encompasses any transfer of money, capital, or property between the foreign owner and the LLC:
Capital Contributions & Injections
Initial capital deposits used to pay state incorporation fees, registered agent expenses, or fund business checking accounts.
Owner's Draws & Profit Distributions
Any profit withdrawals transferred from the LLC's US bank account to the foreign owner's personal account abroad.
Business Expense Reimbursements
Personal funds spent by the foreign owner to purchase company domain names, web hosting, or software tools on behalf of the LLC.
3. How to Prepare Pro-Forma Form 1120 Attachment
Form 5472 cannot be filed as a standalone document. The IRS strictly mandates that it must be attached to a pro-forma Form 1120 (U.S. Corporation Income Tax Return).
On the pro-forma Form 1120, you complete company identity fields (Entity Name, US Address, EIN, Date Incorporated) and write "Foreign-owned U.S. DE" across the top of Page 1. Financial lines for income, deductions, and tax liability are left blank because pass-through tax rules apply.
