What this form asks for

The AI fills all of it, from your answers or your documents.

Form 5472 is an IRS information return required when a U.S. corporation is at least 25% foreign-owned, or when a foreign corporation is engaged in a U.S. trade or business, and there are reportable transactions with related parties. The form identifies the reporting corporation, its 25% foreign shareholder(s), and related party(ies), and summarizes monetary and certain nonmonetary transactions (such as sales, services, rents, royalties, loans, and cost sharing). It is important because it provides the IRS visibility into cross-border related-party dealings and transfer-pricing-related activity, and failure to file accurately and timely can trigger significant penalties.

The AI checks your answers before you download

17 checks built for this form, so a wrong date or a missing answer is caught before anyone else sees it.

Tax Year Begin/End Dates Present and Valid

Validate that the tax year beginning and ending dates are both provided and are valid calendar dates in an accepted format (e.g., MM/DD/YYYY). Confirm the ending date is after the beginning date and that the period length is reasonable for the filer (typically 12 months unless a short year is indicated). If this validation fails, the submission should be rejected or routed for correction because the tax period determines which transactions and thresholds apply.

Reporting Corporation Name and U.S. Address Completeness

Ensure the reporting corporation’s legal name and full address fields (street, city, state/province, and ZIP/postal code) are completed and in English as required by the form. For U.S. addresses, validate state is a valid USPS abbreviation and ZIP is 5 digits (or ZIP+4). If incomplete or improperly formatted, the filing may be unprocessable and should be flagged for correction.

Employer Identification Number (EIN) Format Validation

Check that the EIN is present and matches the required 9-digit format (NN-NNNNNNN or NNNNNNNNN), disallowing SSN-like patterns where applicable. Also validate that the EIN is not all zeros and does not contain non-numeric characters beyond an optional hyphen. If invalid, the form should fail validation because EIN is a primary identifier used for matching and compliance.

Total Assets (Line 1c) Currency and Non-Negative Check

Validate that total assets is provided as a U.S. dollar amount, numeric, and non-negative, with at most two decimal places. Reject values containing currency symbols beyond optional formatting, commas in wrong positions, or negative amounts unless explicitly allowed by business rules (generally not for assets). If this fails, downstream computations and reasonableness checks cannot be performed reliably.

Principal Business Activity and Activity Code Consistency

Ensure both the principal business activity description (Line 1d) and the principal business activity code (Line 1e) are provided and that the code is in the expected numeric format (typically 6 digits). Validate that the code is a valid IRS business activity code and is consistent with the text description (e.g., not a manufacturing code with a services description). If inconsistent or missing, the submission should be flagged because classification affects reporting and analytics.

Gross Payments Totals: Line 1f/1h and Form Count (Line 1g) Logical Consistency

Validate that Line 1g (total number of Forms 5472 filed) is a positive integer when any gross payments are reported, and that Lines 1f and 1h are valid U.S. dollar amounts. Enforce that Line 1h (all Forms) is greater than or equal to Line 1f (this Form) and that Line 1h is not populated with Line 1g equal to zero. If this fails, the filing should be rejected or flagged because totals across forms must reconcile for compliance.

How to Fill Out Form 5472 Online for Free in 2026

What the AI walks you through.

  1. Enter the tax year covered and complete Part I with the reporting corporation’s legal name, address, EIN, total assets, business activity/code, incorporation details, and totals for gross payments and number of Forms 5472 filed.
  2. Complete Part II by listing each direct and ultimate indirect 25% foreign shareholder, including names/addresses, U.S. identifying number or reference ID, FTIN (if any), and countries of incorporation/residency and where business is conducted.
  3. Complete Part III by identifying the related party involved in the reportable transactions, indicating whether the related party is a foreign person or U.S. person, and providing identifying numbers, business activity/code, relationship checkboxes, and residency/business countries.
  4. If the related party is foreign, complete Part IV by entering U.S.-dollar amounts for each category of monetary transactions (receipts and payments), including inventory/property sales and purchases, services, rents/royalties, intangibles, loans/interest, insurance, guarantees, and other amounts, then total the sections.
  5. If applicable, complete Parts V and VI by attaching required statements describing other reportable transactions for a foreign-owned U.S. disregarded entity and any nonmonetary or less-than-full-consideration transactions, and check the corresponding boxes.
  6. Answer Part VII additional information questions (imports, cost sharing participation, section 267A disallowed interest/royalty, FDII-related amounts, safe-haven interest rate loans, and covered debt instrument questions) and complete a separate Part VIII for each cost sharing arrangement if required.
  7. If applicable, complete Part IX for base erosion payments and tax benefits under section 59A, then review for consistency, ensure all required attachments are included, and file Form 5472 with the reporting corporation’s income tax return (or as required for foreign-owned U.S. disregarded entities).

Common Mistakes in Completing Form 5472

The ones the AI is built to catch.

Leaving the tax year beginning/ending dates blank or inconsistent with the return
Filers often overlook the header line for the reporting corporation’s tax year or enter dates that don’t match the corporation’s Form 1120/1120-F (or the entity’s actual accounting period). This creates processing mismatches and can trigger IRS correspondence or rejection of the filing package. Use the exact tax year start and end dates used on the income tax return (or pro forma return for foreign-owned U.S. disregarded entities) and keep them consistent across all attached Forms 5472.
Using non-English entries or non-USD amounts (or failing to convert currency properly)
Because the form requires all information in English and money items in U.S. dollars, people commonly paste foreign-language legal names/addresses or report amounts in local currency. This can lead to unclear identification of parties and incorrect totals, which increases audit risk and follow-up requests. Translate names/addresses into English where appropriate and convert all monetary amounts to USD using a consistent method (and retain the exchange-rate support in your records).
Incorrect or missing EIN for the reporting corporation (Part I, line 1b)
A frequent error is entering an SSN/ITIN instead of the corporation’s EIN, transposing digits, or leaving the EIN blank (especially for newly formed entities or foreign-owned U.S. disregarded entities). An incorrect EIN can prevent proper matching to the tax return and may result in penalties or notices. Confirm the EIN from the IRS assignment letter (CP 575) or prior filings and ensure it matches the name on line 1a.
Misreporting total assets (Part I, line 1c) or using book values inconsistently
Filers often enter total assets from the wrong financial statement, omit year-end adjustments, or report in thousands while the form expects full dollars. This can make the filing internally inconsistent and raise questions about the corporation’s size and reporting completeness. Use the same basis and year-end date as the tax return balance sheet (Schedule L, if applicable) and report the full USD amount without scaling unless explicitly instructed.
Choosing the wrong principal business activity and code (Part I, lines 1d–1e; Part III, lines 8c–8d)
People commonly enter a narrative activity that doesn’t align with the IRS activity code list, use an outdated code, or copy a code from another entity that has a different primary revenue source. Incorrect codes can cause classification issues and may prompt questions about whether the right transactions were reported. Select the code that best matches the entity’s primary activity for the year and ensure the description and code agree.
Not checking the correct status boxes (initial year, consolidated filing, 50% ownership, or foreign-owned U.S. DE)
Checkboxes in Part I (for consolidated filing and initial year) and lines 2–3 are frequently missed or checked incorrectly because filers misunderstand the ownership thresholds or disregarded-entity rules. Wrong selections can lead to incomplete reporting, missing required attachments, or incorrect expectations about how many Forms 5472 should be filed. Review ownership during the entire tax year, confirm whether the filer is a foreign-owned U.S. disregarded entity treated as a corporation for 6038A purposes, and only check consolidated filing if you meet the specific IRS conditions.
Omitting required 25% foreign shareholder details or confusing direct vs. ultimate indirect owners (Part II)
A common mistake is listing only the immediate owner when an ultimate indirect 25% foreign shareholder must also be disclosed, or mixing up “direct” and “ultimate indirect” entries. This can make the ownership chain unclear and may be treated as an incomplete Form 5472. Map the ownership structure for the entire year, list each required direct and ultimate indirect 25% foreign shareholder in the correct lines, and ensure names/addresses and country fields are complete.
Leaving identifying numbers blank without providing a Reference ID number (Parts II and III, lines 4b/5b/6b/7b/8b)
Filers often don’t have a U.S. identifying number or FTIN for a foreign party and then leave all identifier fields empty, not realizing a Reference ID number is expected when other IDs are unavailable. Missing identifiers can delay processing and increase the chance of IRS follow-up because the related party cannot be reliably matched. If no U.S. TIN or FTIN exists, create and consistently use a unique Reference ID number for that party across all filings and years, following the instructions.
Failing to complete Part III correctly (related party type and relationship boxes)
People frequently forget to indicate whether the related party is a foreign person or U.S. person, or they check the wrong relationship boxes in line 8e. This matters because it determines whether Part IV is required and how transactions should be interpreted. Confirm the related party’s status and relationship to the reporting corporation and the 25% foreign shareholder, and ensure the Part III heading selection aligns with the transactions you report.
Misclassifying or netting transactions in Part IV (reporting net amounts, wrong lines, or missing loans/interest details)
A very common error is netting payments (e.g., reporting only the net of purchases and returns), combining different transaction types into “Other,” or omitting required beginning/ending balances for amounts borrowed/loaned. Misclassification can understate reportable amounts and create inconsistencies with transfer pricing documentation or financial records. Report gross payments by category on the correct lines, avoid netting unless instructions explicitly allow it, and complete both balance fields for loans (including whether you used ending balance or monthly average).
Forgetting to attach required statements for Parts V and VI (and for import valuation explanations in Part VII)
Filers often check the box indicating additional reportable transactions (Part V) or nonmonetary/less-than-full consideration transactions (Part VI) but fail to attach the separate sheet description, or they answer “Yes” to Part VII import valuation questions and forget the required explanation statement. Missing attachments can make the filing incomplete and may trigger IRS notices or penalties. When a part requires an attached description, include a clearly labeled statement with enough detail to identify the transaction, parties, dates, and amounts (or valuation method).

What is Form 5472 used for?
Form 5472 is an IRS information return used to report certain transactions between a 25% foreign-owned U.S. corporation (or a foreign corporation engaged in a U.S. trade or business) and its related parties. It is filed under Internal Revenue Code sections 6038A and 6038C.
Who is required to file Form 5472?
You generally must file if you are a U.S. corporation that is at least 25% foreign-owned at any time during the tax year, or a foreign corporation engaged in a U.S. trade or business with reportable related-party transactions. The form is also used by certain foreign-owned U.S. disregarded entities treated as corporations for section 6038A purposes.
What does “25% foreign-owned” mean for this form?
It means a foreign person owns, directly or indirectly, at least 25% of the total voting power or total value of the corporation’s stock. The form also asks whether any foreign person owned at least 50% at any time during the year (Part I, line 2).
What information must be completed in Part I (Reporting Corporation)?
All reporting corporations must complete Part I, including the corporation’s name, address, EIN, total assets, principal business activity and code, and totals for gross payments reported. You also indicate items like initial-year filing, consolidated filing, and country/date of incorporation.
Do I have to report amounts in a specific language or currency?
Yes. The form instructs you to enter all information in English and report all money items in U.S. dollars.
How do I complete Part II (25% Foreign Shareholder) if the shareholder doesn’t have a U.S. identifying number?
If the shareholder has no U.S. identifying number, you may need to use a Reference ID number as indicated on the form. If available, you can also provide a foreign taxpayer identification number (FTIN) in the FTIN field.
What is the difference between a “direct” and an “ultimate indirect” 25% foreign shareholder in Part II?
A direct 25% foreign shareholder owns the reporting corporation directly. An ultimate indirect 25% foreign shareholder owns through one or more entities in the ownership chain and is the top foreign owner meeting the 25% threshold.
What is Part III (Related Party) and do I always have to fill it out?
Part III identifies the related party involved in the reportable transactions and whether that related party is a foreign person or a U.S. person. All reporting corporations must complete the Part III question and the rest of Part III.
When do I have to complete Part IV (Monetary Transactions)?
Part IV must be completed if the related party in Part III is checked as a “foreign person.” You report monetary amounts for categories such as sales/purchases, rents, royalties, services, commissions, loans, and interest paid/received.
Can I use estimates for the transaction amounts in Part IV?
Yes, the form includes a checkbox to indicate that estimates were used. If you use estimates, you should be consistent and maintain support for how the amounts were determined.
How do I report loans between the reporting corporation and the related party on Form 5472?
Loans are reported in Part IV as “Amounts borrowed” (line 17) and “Amounts loaned” (line 31), including beginning and ending balances (or monthly average, as applicable). Interest paid or received is reported separately on lines 18 and 32.
What are Parts V and VI, and when do I attach a separate statement?
Part V applies to a reporting corporation that is a foreign-owned U.S. disregarded entity and requires describing certain additional reportable transactions (such as formation, dissolution, contributions, and distributions) on an attached sheet. Part VI requires an attached description for nonmonetary or less-than-full consideration transactions with a foreign related party.
What additional questions are asked in Part VII, and why do they matter?
Part VII asks about items such as importing goods from a foreign related party, cost sharing arrangements, disallowed interest/royalty deductions under section 267A, FDII-related amounts, safe-haven interest rate loans, and certain related-party debt instrument transactions. These questions help the IRS understand transfer pricing, documentation, and other cross-border tax issues.
When do I need to complete Part VIII (Cost Sharing Arrangement)?
You complete Part VIII only if the reporting corporation was a participant in a cost sharing arrangement (CSA) during the tax year (Part VII, line 39). A separate Part VIII is required for each CSA, and you must report the requested CSA details and amounts in U.S. dollars.
What is Part IX (Base Erosion Payments and Tax Benefits) used for?
Part IX is used to report amounts related to base erosion payments and base erosion tax benefits under section 59A, as well as qualified derivative payments. This section is relevant for corporations that may be subject to the base erosion and anti-abuse tax (BEAT) rules.
