1. What is IRS Form 5472 & Pro Forma Form 1120?
IRS Form 5472 is an informational return titled "Information Return of a 25% Foreign-Owned U.S. Corporation or Foreign Corporation Engaged in a U.S. Trade or Business."
Because a single-member LLC is treated as a "Disregarded Entity" for tax purposes, it cannot file Form 5472 on its own. The IRS requires you to attach Form 5472 to a "Pro Forma" Form 1120 (US Corporation Income Tax Return).
The IRS imposes an automated, non-discretionary penalty of $25,000 for failure to file Form 5472 on time, filing an incomplete return, or failing to maintain required accounting records. If the failure continues after IRS notification, an additional $25,000 is assessed every 30 days!
2. Who is Legally Required to File?
You must file Form 5472 and Pro Forma 1120 if your business meets these 3 conditions:
- Your entity is a single-member US LLC organized in any of the 50 US states.
- The LLC is 100% directly or indirectly owned by a non-US individual or foreign entity.
- The LLC engaged in at least one "Reportable Transaction" during the tax year.
3. What Counts as a Reportable Transaction?
Almost every single-member LLC engages in reportable transactions. A reportable transaction is any movement of money or property between the foreign owner and the LLC:
Depositing your own personal funds into the US business account (Wise, Payoneer) to fund inventory or state filing fees.
Withdrawing profits from the LLC bank account to your personal bank account in Pakistan or elsewhere.
Payments made by the owner on behalf of the company for registered agent fees, web hosting, or software tools.
Crucial Takeaway: Even if your business generated $0 in sales, transferring $100 into the LLC to pay for banking or registered agent services triggers mandatory Form 5472 reporting!
4. Zero Tax Liability vs. Mandatory Informational Reporting
It is vital to understand the difference between paying taxes and filing reports:
- Federal Tax Liability ($0): If you operate remotely from Pakistan with no US employees, no physical office, and no dependent agent in the US, you are generally not ETBUS (Engaged in Trade or Business in the United States). Your foreign-sourced profits carry 0% US federal tax liability.
- Informational Reporting (Mandatory): Form 5472 does not calculate tax owed. It is an international anti-money laundering and transparency disclosure. Filing is 100% compulsory regardless of profit or loss.
5. Step-by-Step Filing Instructions for Form 5472 & 1120
Pro Forma Form 1120
Only complete the top section: Company Name, US Address, EIN, and Incorporation Date. Write "Foreign-owned U.S. DE pursuant to section 1.6038A-2" across the top margin. Leave lines 1 through 31 blank.
Form 5472: Part I (Reporting Corporation)
Declare your LLC's legal name, EIN, and primary business activity code.
Form 5472: Part II (25% Foreign Shareholder)
Provide your full legal name, Pakistani residential address, citizenship, and foreign tax identification number (Pakistani CNIC / NTN).
Form 5472: Part IV & Part VI (Monetary Transactions)
Disclose the exact dollar amounts transferred between you and the LLC: capital contributions, distributions, and loan balances.
6. How to Submit to the IRS: Certified Fax vs. Mail
Disregarded entities cannot e-file Form 5472 through commercial consumer tax software. Submissions must be sent via:
- IRS Dedicated International Fax (Recommended): Transmit directly to +1 (855) 887-0029. Retain the certified electronic fax confirmation receipt as absolute legal proof of on-time filing.
- International Registered Mail: Mail physical signed copies via DHL or FedEx to the IRS Internal Revenue Service Center in Ogden, Utah.
7. Deadlines, Form 7004 Extensions & The $25,000 Penalty
For calendar-year entities, Form 5472 is due on April 15 of the following year. If you need extra time, submit IRS Form 7004 on or before April 15 to secure an automatic 6-month extension to October 15.

9. Frequently Asked Questions (FAQs)
Do multi-member LLCs file Form 5472?
No. Multi-member LLCs are treated as partnerships for US federal tax purposes and file IRS Form 1065 with Schedule K-1s instead.
Do I need an ITIN or SSN to file Form 5472?
No. The LLC requires an IRS EIN, but the foreign owner can enter their home country tax identification number (Pakistani CNIC / NTN) on Part II.
What happens if my LLC made no sales?
If zero funds moved between the foreign owner and the LLC all year, no filing is required. However, almost every active LLC pays state renewal or banking fees, which count as reportable capital injections.
