Form 5472 has nine parts and dozens of fields. Most do not apply to foreign-owned single-member LLCs. This guide walks through every part, identifying which fields you complete, which to leave blank, and what to enter where the form's wording is ambiguous for disregarded entity filers.
Which parts of Form 5472 a disregarded entity actually completes
For a foreign-owned single-member LLC treated as a disregarded entity, the key fields are: Part I (reporting corporation identification), Part II (foreign related party information), and Part V (reportable transactions). Most foreign-owned DE filers leave Parts III, IV, VI, VII, and VIII blank. The form is filed with a Pro Forma 1120 cover sheet and mailed to the dedicated Ogden, Utah address. Always check the latest revision at IRS.gov/Form5472 before filing.
Before you start
Form 5472 (Rev. December 2023) is the form revision in use, with Instructions Rev. December 2024. Verify the current version before each filing because the IRS updates these documents periodically. Across the top of the Pro Forma 1120 attached as cover sheet, write "Foreign-owned U.S. DE" in handwriting or typed.
Part I - Reporting Corporation Identification
This block identifies your LLC.
| Line | What to enter |
|---|---|
| 1a - Name | The LLC's full legal name as on the formation documents and the EIN assignment letter. |
| 1a - Address | The LLC's principal business address. For most foreign-owned LLCs this is the registered agent's address or the Mercury or Brex business address on file. |
| 1b - EIN | The LLC's EIN exactly as on the IRS assignment letter. An LLC without an EIN cannot file; apply on Form SS-4 first. |
| 1c - Total assets | Total assets at year-end, usually cash plus any other assets. A newly formed LLC can enter the formation contribution amount. |
| 1d - Principal business activity | A brief description, such as "Software development services", "E-commerce sales" or "Consulting services". |
| 1e - NAICS code | Common codes: 541511 custom programming, 541613 marketing consulting, 454110 e-commerce, 519130 internet publishing. |
| 1f - Total gross payments on this Form 5472 | The sum of monetary transactions reported in Parts IV and V. Calculate it after completing those parts. |
| 1g - Total Forms 5472 filed for the year | "1" for most single-related-party cases. |
| 1h - Total payments across all Forms 5472 | The sum across every Form 5472, where more than one was filed. |
| 1i - Consolidated filing | Generally left blank for foreign-owned single-member LLCs. |
| 1j, 1k - Country of incorporation, country of tax filing | "United States" for a US-formed LLC. |
| 1l - Date of incorporation | The LLC formation date as on the state documents. |
| 1m - Principal business country | Where the business is conducted. Often the owner's country plus the US, or just the owner's country where delivery is remote. |
Part II - Foreign Related Party Information
This identifies the foreign related party. For most foreign-owned single-member LLCs, this is the foreign owner personally.
| Line | What to enter |
|---|---|
| 2a - Name and foreign address | The foreign owner's full legal name and foreign address, including city, province or state, and country. |
| 2b - US identifying number | ITIN or SSN if the owner has one. Most foreign owners do not; leave blank if it does not apply. |
| 2b(1) - Reference ID number | Required for a related party with no US identifying number. Assign a consistent format such as "FRP-001-LLCNAME" and reuse the same reference ID in later years. |
| 2c - Foreign taxpayer identification number | The country-specific ID: PAN for India, NTN for Pakistan, TRN for the UAE, UTR for the UK, SIN for Canada. |
| 2d, 2e - Country of organization, citizenship and residence | For an individual, country of citizenship and country of residence. |
| 2f, 2g - Business country, tax filing country | Where the related party operates and where it files. |
| Lines 4-7 - Multiple related parties | Use an additional Part II block per foreign related party. Most single-member cases use only Line 2. |
Part III - Related Party Information for Foreign Corporations Engaged in US Trade or Business
Generally not applicable for foreign-owned single-member LLCs. Leave blank.
Part IV - Monetary Transactions Between Reporting Corporation and Foreign Related Party
Part IV is structured for traditional 25% foreign-owned U.S. corporations. Most foreign-owned single-member LLCs use Part V instead, which is designed specifically for foreign-owned U.S. DEs. The IRS instructions distinguish these explicitly.
If you are filing for a foreign-owned single-member LLC, Part IV typically remains blank. Part V is where reportable transactions are listed.
Part V - Reportable Transactions of a Reporting Corporation That Is a Foreign-Owned U.S. DE
This is the key reporting section for foreign-owned single-member LLCs.
Line 12 (Reportable transactions). Free-form description of reportable transactions during the year. Examples:
- "Capital contribution of $500 from foreign owner on March 15, 2025 to fund LLC formation expenses"
- "Distributions of $12,000 to foreign owner across four payments dated April 30, June 15, September 1, and December 1, 2025"
- "Loan of $5,000 from foreign owner on June 1, 2025; outstanding at year-end"
For a typical first-year foreign-owned LLC, the entry covers the formation contribution. For ongoing years, the entry covers all capital movement between the LLC and foreign related parties.
Part VI - Nonmonetary and Less-Than-Full Consideration Transactions
Most foreign-owned single-member LLCs do not have nonmonetary transactions. Services exchanged without market-rate compensation, property transfers without payment, or other non-cash exchanges go here. Leave blank for typical operating LLCs.
Part VII - Additional Information
Lines 14-17. Most foreign-owned single-member LLCs answer "No" to these questions. They cover cost-sharing arrangements, qualified intermediaries, and base erosion (BEAT under §59A). BEAT applies only to large corporations with significant deductible payments to foreign related parties; small LLCs do not meet the thresholds.
Part VIII - Cost-Sharing Arrangement
Generally not applicable. Leave blank.
Part IX - Information About the Reporting Corporation's Common Parent
Most foreign-owned single-member LLCs do not have a US-based common parent. Leave blank unless the LLC is part of a US affiliated group.
What to enter on the Pro Forma 1120
The Form 1120 attached as cover sheet is mostly blank. Complete only:
- Heading: Write "Foreign-owned U.S. DE" across the top
- Line A: Check appropriate box (Initial return for first-year filings, etc.)
- Line C: LLC formation date
- Line D: Total assets (match Form 5472 Line 1c)
- Name and address block: matching Form 5472
- EIN: LLC's EIN
Leave all income, deduction, and tax computation lines blank. The Pro Forma 1120 does not compute tax.

Field-level questions
Do I report transactions in US dollars?
Yes. Convert non-USD transactions using a reasonable exchange rate (typically the rate on the transaction date or year-end rate for cumulative balances). The IRS does not specify a required source; published rates from financial news services or OECD are commonly used.
What if my LLC's tax year is not calendar year?
Most single-member LLCs use the calendar year by default. If you elected a fiscal year, enter the fiscal year dates on Line 1c. The April 15 deadline shifts to the 15th of the fourth month after fiscal year-end.
What if I have multiple foreign related parties?
Each foreign related party requires its own Part II identification (Lines 2-7 cover up to four parties). Additional related parties require additional Forms 5472 or a consolidated filing per Treas. Reg. §1.6038A-2(b).
How do I report a loan that has not been repaid?
Report the outstanding balance and any interest accrued or paid in Part V. The form captures the year's transactions and end-of-year position. If the loan continues into subsequent years, report it again each year until repaid.
What if I made a small mistake in a previous year's filing?
File an amended Form 5472 for the prior year, marking it as amended at the top. The amended return goes to the same Ogden address. There is no specific amended Form 5472 form; you re-file the standard Form 5472 with corrections.
Is there a penalty for filing the form with errors?
A "substantially incomplete" Form 5472 is treated as a failure to file under Treas. Reg. §1.6038A-4. Minor clerical errors typically do not trigger penalty. Material omissions of related parties or significant transactions can. Filing with reasonable diligence and amending if errors are discovered is the appropriate posture.
What do I put in Part I if the LLC has no EIN?
Form 5472 cannot be filed without an EIN for the LLC. The reporting corporation's identifying number in Part I is required, and there is no "applied for" option that the Ogden unit will process. Apply for the EIN first on Form SS-4, then file. A missing EIN is the most common reason a foreign-owned DE packet cannot be filed at all.
My foreign owner has no US tax identification number. What goes in Part II?
Part II asks for the foreign related party's identifying number if one exists. A foreign individual with no ITIN and no SSN has no US number to give, and the foreign tax identification number issued by their own country goes in the corresponding field instead. Leaving both blank when a foreign number exists is an incomplete filing.
Do I complete Item C and Item D on the pro forma 1120?
No, they are not required. The only information required on the pro forma Form 1120 is the name and address of the foreign-owned US DE and items B and E on page 1. Items C (date incorporated) and D (total assets) may be completed, and where completed they must agree with Form 5472 Line 1c and the formation date. Complete both or neither.
Where does "Foreign-owned U.S. DE" go?
Across the top of the Form 1120, not on Form 5472. It is the marker the Ogden unit uses to route the packet, and a pro forma 1120 without it is the most common cause of a packet being processed as an ordinary corporate return.
