Statutory Basis: 26 U.S. Code § 6038A, Treasury Reg. § 1.6038A-2 & § 1.6038A-1(h)

Executive Statutory Takeaways

Every foreign-owned US Single-Member LLC is legally classified as a reporting corporation under IRC § 6038A.

The mandatory filing consists of an informational pro-forma Form 1120 accompanied by Form 5472.

The statutory penalty for failing to file, late filing, or filing an incomplete return is $25,000 PER YEAR (IRC § 6038A(d)(1)).

Even if the LLC generated $0 in revenue or owes $0 in federal tax, the filing is still legally required if reportable transactions occurred.

Reportable transactions include owner capital contributions, distributions, formation fee reimbursements, and inter-company loans.

1. The Statutory Mandate of IRC § 6038A

In 2017, Treasury promulgated final regulations under Treasury Decision 9796 (effective for tax years beginning on or after January 1, 2017), ending the era of anonymous, unmonitored foreign-owned domestic disregarded entities. Pursuant to Treasury Regulation § 1.6038A-1(c)(1), a domestic Single-Member LLC that is disregarded as an entity separate from its owner is treated as a domestic corporation for the sole purpose of information reporting under Section 6038A. This means: - The LLC does NOT pay corporate income tax. - The LLC MUST file an annual informational tax package. - The package requires an informational 'pro-forma' Form 1120 acting as a cover vehicle, attached to a fully completed Form 5472 (Information Return of a 25% Foreign-Owned U.S. Corporation or Foreign Corporation Engaged in a U.S. Trade or Business).

Statutory Authority: Treas. Reg. § 1.6038A-1(c)(1)

A domestic business entity that is wholly owned by one foreign person and that is otherwise classified as an entity that is disregarded as an entity separate from its owner... is treated as a domestic corporation for purposes of section 6038A.

2. The $25,000 Statutory Failure-to-File Penalty

Unlike ordinary personal returns where late-filing penalties are calculated as a percentage of unpaid tax, the IRS penalty for Form 5472 is an automatic, non-negotiable statutory assessment. Under IRC § 6038A(d)(1): - A penalty of $25,000 is assessed for failure to timely file Form 5472 or failure to maintain required records. - If the failure continues for more than 90 days after the IRS mails notice of failure, an additional $25,000 penalty is assessed for each 30-day period (or fraction thereof) that the failure continues, with NO statutory ceiling. - The penalty applies even if the company owes exactly $0.00 in federal income tax. The IRS computer matching system automatically assesses this fine if the return is late or sent to the wrong service center.

Strict Statutory Penalty

26 U.S. Code § 6038A(d)(1) mandates a $25,000 civil penalty for each failure to furnish required information within the prescribed time.

3. What Constitutes a Reportable Transaction?

Form 5472 requires reporting all monetary exchanges between the foreign owner (or any related party) and the US LLC during the calendar year (Part IV). Common Reportable Transactions include: 1. Capital Contributions: When you deposit personal funds from your foreign bank account to fund the LLC's Mercury account or pay state filing fees. 2. Owner Distributions: Withdrawing business profits from the US LLC bank account to your personal foreign bank account. 3. Loans & Advances: Any loan made by the foreign member to the LLC or vice versa. 4. Services & Royalties: Any fee paid to the foreign owner for management or software development. If you formed an LLC during the year and deposited even $100 for capitalization, you engaged in a reportable transaction and MUST file.

Zero-Activity Inactive Entities

If an entity had literally zero transactions, zero deposits, zero capital contributions, and zero bank account activity, some practitioners take the position that no Form 5472 is required; however, the gold standard recommendation is always filing a zero return to start the statute of limitations clock.

4. Pro-Forma Form 1120 & Form 5472 Architecture

How to correctly prepare the return package: Step 1: Pro-Forma Form 1120 - Header: Enter the LLC's Legal Name, US Registered Agent Address, EIN, and Date Incorporated. - Box E: Check the box for 'Initial Return' or 'Final Return' as appropriate. - Top Margin: Write clearly across the very top: 'Foreign-owned U.S. DE pursuant to Treas. Reg. § 1.6038A-2'. - Body of Form 1120: Leave lines 1 through 31 entirely BLANK. Do not compute tax or report deductions here. Only sign the signature block. Step 2: Form 5472 - Part I: Complete details for the reporting corporation (the US LLC). - Part II: Complete details for the 25%+ foreign shareholder (your name, foreign address, foreign tax ID number, nationality). - Part IV: Document total dollar amounts for capital contributions, profit distributions, and inter-company transfers.

5. Deadlines, Extensions (Form 7004), and Transmission

Calendar Deadlines: - Standard Filing Deadline: April 15 of the year following the tax year. - Automatic 6-Month Extension: Filing Form 7004 on or before April 15 extends the filing deadline to October 15. How to Transmit the Return: Because foreign-owned disregarded entities do not file a standard electronic corporate return, you CANNOT e-file through standard consumer software (TurboTax). The return must be submitted via: - Official IRS Fax Processing Gateway: Dedicated fax line for Section 6038A filings: +1-855-887-0029. - Certified Mail / Courier (DHL / FedEx): Addressed to Internal Revenue Service, 201 West Rivercenter Blvd, Covington, KY 41011.
