The short answer
Key takeaways
Our sample filer is Maria Silva, a resident of Brazil who owns 100% of Silva Trading LLC, a Wyoming LLC. During 2025 she contributed $10,000 of capital to start it and had no other related-party transactions. That single contribution is her one reportable transaction.
To make the example concrete, we use a realistic, common fact pattern. Every value below is illustrative, but the structure matches what a typical first-year, foreign-owned single-member LLC actually files.
| Item | Value in the example |
|---|---|
| Owner | Maria Silva, resident of Brazil (non-resident alien) |
| LLC | Silva Trading LLC, formed in Wyoming |
| Ownership | 100% foreign-owned, single member |
| LLC EIN | 98-7654321 (illustrative) |
| Reportable transaction | $10,000 capital contribution from the owner |
| Tax year | 2025 (calendar year) |
| Filing method | Mail or fax with a pro forma Form 1120 |

With these facts, only one reportable transaction exists — the capital contribution — which is the most common situation by far. The deep dive on why funding the LLC is reportable is at /capital-contribution-form-5472/.
Part I identifies the US reporting entity. In the example: the LLC’s name (Silva Trading LLC), US address, EIN 98-7654321, total assets, principal business activity, and country of incorporation (United States). This is the LLC itself, not the owner.
Part I is the “who is filing” block — it describes the US LLC. You complete the identity lines exactly as they appear on the LLC’s formation documents and EIN letter.
| Line | Entry in the example |
|---|---|
| Name of reporting corporation | Silva Trading LLC |
| Number, street, city, state | The LLC's US business or registered address |
| Employer identification number (EIN) | 98-7654321 |
| Total assets | $10,000 (the contributed capital) |
| Principal business activity + code | e.g., Online retail / 454110 |
| Country of incorporation | United States |
| Total value of gross payments (Part IV/VI) | Carried from the transaction parts |

Note the LLC writes its ownEIN here. The owner’s identifying number is a separate matter handled in Part II.
Part II identifies the 25% foreign shareholder. In the example: Maria Silva, Brazil, with her Brazilian tax ID and a reference ID number (because she has no US EIN). This is where the form names the foreign owner.
Part II describes the foreign owner — the related party on the other side of the reportable transaction. Because a non-resident individual usually has no US taxpayer identification number, this is where the reference ID number appears.
| Line | Entry in the example |
|---|---|
| Name of 25% foreign shareholder | Maria Silva |
| Address | Her permanent residence address in Brazil |
| U.S. identifying number, if any | (blank — she has no US EIN/SSN/ITIN) |
| Reference ID number | 98-7654321-001 (LLC EIN + sequence) |
| Foreign taxpayer identification number | Her Brazilian CPF/tax ID |
| Country of citizenship / organization | Brazil |

The reference ID number is a unique identifier you create when the owner has no US number. How to construct and assign it is explained in full at /form-5472-reference-id-number/.
Part III names the related party (Maria, the same owner). Parts V and VI report the $10,000 capital contribution— the LLC’s single reportable transaction. For this simple case, the contribution is the only amount entered in the transaction parts.
These parts carry the actual money. Part III identifies whom the transactions were with; Parts V and VI record what those transactions were. In our example there is exactly one: the owner’s $10,000 capital contribution.
| Part | Entry in the example |
|---|---|
| Part III — Related party | Maria Silva (the foreign owner), Brazil, same reference ID |
| Part V — Reportable transactions of a DE | Description of the $10,000 capital contribution from the owner |
| Part VI — Other amounts | $10,000 capital contribution summarized among 'other' transactions |
| Parts IV, VII–IX | Blank — no service payments, base-erosion items, or cost-sharing here |

Because Maria paid herself nothing and the LLC paid her nothing, Part IV (monetary transactions for services, rent, royalties) stays empty, and the advanced parts for large multinationals do not apply. For a fuller list of what would go in each part if there were more transactions, see /form-5472-reportable-transaction/.
The pro forma Form 1120 shows only the top block: Silva Trading LLC, its US address, EIN 98-7654321, and date formed, with “Foreign-owned U.S. DE” written across the top. Every income and tax line stays blank. Form 5472 is attached behind it.
Form 5472 cannot go to the IRS by itself — it must ride on a return. For a disregarded entity, that return is a pro forma Form 1120: a shell you complete only at the top. In the example, the pro forma 1120 carries Silva Trading LLC’s identity and nothing else.
| Field | Entry / status |
|---|---|
| Name, address, EIN | Silva Trading LLC, US address, 98-7654321 |
| Date incorporated | The LLC's Wyoming formation date |
| Top margin notation | 'Foreign-owned U.S. DE' written across the top |
| Income, deductions, tax lines | Blank — no entity-level income reported |
| Attachment | Form 5472 stapled behind the 1120 |

The completed package — one pro forma 1120 with one Form 5472 attached — is mailed to P.O. Box 149342, Austin, TX 78714-9342, or faxed to 855-887-7737. It cannot be e-filed. Keep the certified-mail receipt or fax confirmation as proof of the filing date. The complete step-by-step is in /how-to-file-form-5472/.
An example helps you understand the form, but a single error or omission carries a $25,000penalty. Many founders use the example to learn, then have a specialist prepare and file the real form for a flat $299 to remove the risk entirely.
This example is meant to demystify Form 5472 — to show that, for a simple LLC with one capital contribution, the form is not mysterious. But understanding the form and filing it without error are different things. The penalty for a substantially incomplete or incorrect Form 5472 is the same $25,000 as for not filing at all, and the most common mistakes are subtle: a missing reference ID, an omitted mid-year loan, the wrong filing method, or a blank signature.
The cost-benefit is stark. A self-prepared form that looks right but omits one reportable transaction can be treated as not filed. For a flat $299, a specialist captures every transaction, assembles the pro forma 1120 correctly, and files it the accepted way. Use the example to learn what the form contains; let a specialist carry the penalty risk. Note that form5472.tax does not represent clients before the IRS — our service is preparing and filing the return correctly so a penalty never arises.
In a second illustrative case, Maria lends Silva Trading LLC $5,000 mid-year instead of contributing capital. A loan from the owner to the LLC is a separate reportable transaction reported in Part VI, so the form shows the $5,000 amount as money the related party advanced to the disregarded entity.
The first example covered a clean capital contribution. A loan is the next most common fact pattern, and it changes which line carries the money. When Maria wires $5,000 to the LLC as a loan rather than as equity, the substance is different — the LLC owes her the money back — and Form 5472 treats it as its own reportable transaction. All values here remain illustrative and are not real IRS data.
The loan does not go in Part IV (which is reserved for monetary transactions such as service payments, rent, royalties, and interest the LLC actually pays). Instead, amounts loaned to the reporting entity by the related party are summarized in Part VIas non-monetary or other reportable amounts. Maria’s name, Brazil address, and the same reference ID (98-7654321-001) carry over from Parts II and III unchanged.
| Part | Entry in the loan example |
|---|---|
| Part I — Reporting corporation | Silva Trading LLC, EIN 98-7654321 (unchanged) |
| Part II — 25% foreign shareholder | Maria Silva, Brazil, reference ID 98-7654321-001 |
| Part III — Related party | Maria Silva (same owner, same reference ID) |
| Part IV — Monetary transactions | Blank — a loan principal is not a service/rent/royalty payment |
| Part VI — Other amounts | $5,000 loaned to the LLC by the owner |
Illustrative example for educational purposes. Values are not real. Verified against IRS Form 5472 (Rev. December 2025), Part VI, June 2026.
If the LLC later pays Maria interest on that loan, the interest is a separate Part IV item. The full taxonomy of which transactions land where is at /form-5472-reportable-transaction/, and the funding-versus-loan distinction is covered at /capital-contribution-form-5472/.
In a third illustrative case, Silva Trading LLC pays Maria $8,000 for management services she performed. A payment from the LLC to its foreign owner for services is a monetary reportable transaction reported in Part IV, where the $8,000 appears on the line for amounts paid to the related party.
This example introduces Part IV, which the first two examples left blank. Part IV captures monetary transactions between the LLC and the related party — service payments, rent, royalties, commissions, and interest. When the LLC pays its owner $8,000 for services, that cash movement is exactly what Part IV exists to report. Every figure here is illustrative.
Part IV has paired columns — amounts the LLC paid to the related party and amounts it received from them. Maria’s $8,000service fee is an amount the LLC paid, so it lands on the “paid” side. The total of Part IV (and Part VI) flows up to the “total value of gross payments” figure summarized on the Part I block.
| Part IV line | Entry in the services example |
|---|---|
| Amounts paid for services rendered | $8,000 paid to Maria Silva |
| Rents / royalties paid | Blank — none in this example |
| Interest paid | Blank — no loan interest here |
| Amounts received from the related party | Blank — the LLC received nothing back |
| Reference ID of the related party | 98-7654321-001 (carried from Part II) |

Note that paying the owner for services has US tax consequences beyond Form 5472 — it can create US-source income questions and withholding considerations — so the dollar figure on Form 5472 is only part of the picture. The line-by-line walkthrough of Part IV is in /form-5472-instructions/.
In a fourth illustrative case, Maria contributes $10,000 of capital, lends the LLC $5,000, and the LLC distributes $3,000 back to her in the same year. One Form 5472 reports all three: the contribution and distribution in Part VI and the loan in Part VI, with Part IV blank because no service payment occurred.
Real years are rarely a single clean transaction. This example shows how one Form 5472 absorbs several related-party transactions in the same tax year — you do not file a separate form per transaction. All amounts below are illustrative.
The key skill is classification: deciding which part each transaction belongs to. A capital contribution and a distribution of capital are both summarized in the “other amounts” block (Part VI); a loan to the LLC is also a Part VI item; only a payment for services, rent, royalties, or interest would move into Part IV. Because nothing in this example is a service-type payment, Part IV stays empty even though the year was busy.
| Transaction | Amount | Reported in |
|---|---|---|
| Capital contribution from owner | $10,000 | Part VI (other amounts) |
| Loan from owner to LLC | $5,000 | Part VI (other amounts) |
| Distribution from LLC to owner | $3,000 | Part VI (other amounts) |
| Service / rent / royalty payment | $0 | Part IV (left blank) |

The danger in a multi-transaction year is omission: forgetting the mid-year loan or the small distribution. A Form 5472 that omits a reportable transaction can be treated as not filed, exposing the LLC to the full $25,000 penalty. The complete list of what counts is at /form-5472-reportable-transaction/.
A blank pro forma 1120 has empty identity and money lines; a completed one fills only the top block — name, address, EIN 98-7654321, date formed — with “Foreign-owned U.S. DE” across the top and every income and tax line still blank. The contrast is small by design.
Founders often expect the pro forma 1120 to look like a full corporate tax return. It does not. The value of comparing a blank form to the completed example is seeing how little changes — only the identifying header is filled, because a disregarded entity reports no entity-level income on the 1120 itself. Form 5472 carries the substance; the 1120 is just the cover it rides on. The EIN and figures below are illustrative.
| 1120 field | Blank form | Completed in the example |
|---|---|---|
| Name / address | Empty | Silva Trading LLC, US address |
| Employer identification number | Empty | 98-7654321 |
| Date incorporated | Empty | Wyoming formation date |
| Top-margin notation | Empty | 'Foreign-owned U.S. DE' |

The one line people forget on the completed version is the signature — an unsigned 1120 can invalidate the whole package. The end-to-end assembly is detailed in /how-to-file-form-5472/.
The four most common errors are an omitted reportable transaction, a missing reference ID number, an unsigned pro forma 1120, and trying to e-filea disregarded entity’s return. Each can trigger the full $25,000 penalty under IRC §6038A(d), which has no cap and no statute of limitations.
Learning from a good example is only half the lesson — knowing what makes a bad example dangerous is the other half. The errors below recur constantly in self-prepared filings, and each one is individually capable of triggering the penalty.
| Error | Why it happens | Consequence |
|---|---|---|
| Omitted transaction | Forgetting a mid-year loan or distribution | Form can be treated as not filed |
| Missing reference ID | Owner has no US TIN and none is assigned | Part II is incomplete |
| Unsigned 1120 | Treating the cover as a formality | Whole package can be rejected |
| Attempted e-file | Assuming all returns e-file | DE returns must be mailed or faxed |
| Wrong filing address | Using a generic IRS address | Filing may not reach the right unit |

The penalty for a substantially incomplete or incorrect Form 5472 is the same $25,000 as for not filing at all, assessed per form, per year. Because there is no statute of limitations on an unfiled or invalid form, an error can surface years later. Whether you must file at all is covered at /do-i-need-to-file/.
Before mailing the example package, confirm the LLC’s EIN is present, every required part (I, II, III, V, VI) is complete, the reference ID is assigned, the 1120 is signed, and you use certified mail to P.O. Box 149342, Austin, TX 78714-9342 — or fax 855-887-7737 — and keep the proof.
A short final review catches most of the errors above. Run this checklist against the completed example before the package leaves your hands. It maps directly to Maria’s $10,000 capital-contribution filing, and the same checklist scales to the multi-transaction examples.
| Check | What to confirm in the example |
|---|---|
| EIN present | 98-7654321 appears on both the 1120 and Form 5472 (illustrative) |
| All parts complete | Parts I, II, III, V, and VI filled; Part IV only if services/rent paid |
| Reference ID assigned | 98-7654321-001 entered for Maria in Part II |
| DE notation | 'Foreign-owned U.S. DE' written across the top of the 1120 |
| Signature | Owner has signed and dated the pro forma 1120 |
| Filing method | Mailed to Austin TX or faxed — never e-filed |
| Proof kept | Certified-mail receipt or fax confirmation retained |
