Introduction: Why Transaction Reporting Matters
Form 5472 exists primarily to report transactions between foreign-owned U.S. entities and their related parties. The IRS uses this information to identify potential transfer pricing issues, base erosion, and profit shifting.
Understanding what constitutes a reportable transaction is essential for proper compliance. Incomplete transaction reporting is treated the same as failure to file—triggering $25,000 penalties per form. For a comprehensive overview of Form 5472, see our Complete Guide to Form 5472 for Foreign-Owned U.S. Businesses.
Critical Principle: When in doubt, report it. The IRS prefers over-inclusion of transactions rather than omission. Unreported transactions discovered during an examination can result in significant penalties.
2025 OBBBA Update: The One Big Beautiful Bill Act (effective 2026) includes transfer pricing changes that may affect how related-party transactions are structured and priced. FDII is renamed to FDDEI (Foreign-Derived Deduction Eligible Income) with a reduced deduction from 37.5% to 33.34%. Additionally, the new 1% remittance tax on certain cross-border transfers may affect the timing and amount of distributions to foreign owners. Review your intercompany pricing arrangements for 2026 planning.
Who is a “Related Party”?
Before identifying reportable transactions, you must understand who qualifies as a related party.
Related Party Definitions
25% Foreign Shareholder: Any foreign person who owns (directly or indirectly) at least 25% of the reporting corporation’s voting power or value.
Related Party to 25% Foreign Shareholder:
- Parent, grandparent, child, grandchild, or spouse of the shareholder
- Corporations, partnerships, trusts, or estates in which the shareholder owns 25%+
- Any person related to the shareholder under IRC Section 267(b) or 707(b)
Foreign Related Party: Any foreign person that is related to the reporting corporation under the definition above.
Common Related Parties
| Related Party Type | Example |
|---|---|
| Foreign parent company | German corporation that owns 100% of U.S. subsidiary |
| Foreign shareholder | Canadian individual who owns LLC |
| Sister companies | Other U.S. or foreign entities under same ownership |
| Foreign affiliates | Entities with common 25%+ ownership |
| Family members | Spouse or children of foreign owner |
Important: Separate Forms for Each Related Party
You must file a separate Form 5472 for each related party with whom you had reportable transactions. This means:
- 3 related parties = 3 Form 5472s
- 3 related parties × $25,000 penalty = $75,000 exposure

Special Transaction Situations
Formation Transactions
When a foreign-owned entity is first formed, several reportable transactions typically occur:
- Initial capital contribution – Report on Line 24
- Property transfers – Report specific property on Lines 15 or 24
- Organizational expenses – If paid by owner initially
- Startup loans – Report on Line 23
Important: Even if your LLC was formed but had no operational activity, the formation itself creates reportable transactions that must be disclosed.
Dissolution and Liquidation
When winding down a foreign-owned entity:
- Liquidating distributions – Report on Line 26
- Asset sales to related parties – Report by type
- Return of capital – Report on Line 26
- Final settlements – All related party amounts
Loans and Financing
Intercompany loans require careful reporting:
New Loans:
- Principal borrowed: Line 10 or 23
- Interest received/paid: Line 11 or 24
Ongoing Loans:
- Interest payments during the year
- Principal repayments
- Loan modifications
Loan Forgiveness:
- Report on Line 24 or 26 as appropriate
- May have income tax implications
Guaranteed Transactions
When a related party guarantees obligations:
- Report fair market value of guarantee
- May require imputed interest analysis
- Document in supporting records
Transfer Pricing Considerations
Why Transfer Pricing Matters for Form 5472
Form 5472 helps the IRS identify potential transfer pricing issues. All transactions between related parties should be conducted at arm’s length—the price that unrelated parties would agree to.
Arm’s Length Standard
Transactions should reflect prices that would be charged between independent parties in similar circumstances. Consider:
- Comparable uncontrolled transactions
- Resale price method
- Cost plus method
- Profit split method
- Comparable profits method
Documentation Requirements
While Form 5472 reports transaction amounts, you should maintain supporting documentation:
- Intercompany agreements
- Transfer pricing studies
- Comparable transaction analysis
- Economic analysis supporting prices
- Contemporaneous documentation
Record Keeping Requirements
7-Year Retention Rule
Records supporting Form 5472 must be maintained for at least 7 years. Required records include:
Transaction Documentation:
- Invoices and receipts
- Contracts and agreements
- Bank statements
- Wire transfer confirmations
- Payment records
Related Party Information:
- Ownership structure charts
- Related party identification
- Relationship documentation
- EIN/TIN information
Supporting Analysis:
- Transfer pricing documentation
- Valuation reports
- Allocation methodologies
- Contemporaneous memoranda
Where Records Must Be Kept
Records must be available for IRS inspection:
- Maintained within the United States, OR
- Available for production within 60 days of IRS request
Failure to produce required records can result in additional penalties.
Common Transaction Reporting Mistakes
Errors That Trigger Penalties
- Overlooking formation transactions – Initial capital contribution is reportable
- Missing non-monetary transactions – Property use, guarantees, and services at no charge
- Incomplete related party identification – Failing to identify all related parties
- Incorrect transaction categorization – Using wrong form lines
- Netting transactions – Report gross amounts, not net
- Missing intercompany loans – Both principal and interest
- Forgetting distributions – Cash sent to owners
- Ignoring cost allocations – Shared services must be reported
- Omitting intangible property – Trademark and IP use
- Rounding errors – Report to the dollar (no rounding)
Best Practices
- Track all related party transactions throughout the year
- Maintain detailed records contemporaneously
- Use accounting software that flags related party transactions
- Review all accounts payable/receivable for related parties
- Confirm complete related party list before filing
Frequently Asked Questions
Do I report transactions with U.S. related parties?
Form 5472 primarily reports transactions with foreign related parties. However, if you are a foreign-owned U.S. corporation, you may also need to report certain transactions with domestic related parties that are related to your foreign owner.
What if a transaction is zero dollars?
Transactions at no charge (such as free use of property or services without payment) should still be reported. Report the fair market value of what was provided or received.
Should I report transactions at gross or net amounts?
Report gross transaction amounts, not net. If you both bought and sold inventory with a related party, report both amounts separately rather than the net difference.
What’s the threshold for reporting?
There is no minimum threshold. All reportable transactions with each related party must be disclosed regardless of dollar amount.
How do I handle transactions in foreign currency?
Convert foreign currency transactions to U.S. dollars using the exchange rate at the time of the transaction or an appropriate average rate for the year.
What if I’m unsure whether something is reportable?
When in doubt, report it. Over-reporting is far preferable to under-reporting, which can result in the form being treated as substantially incomplete.
Do I need a Form 5472 if all my transactions were with U.S. parties?
If your entity is 25% foreign-owned and you had transactions with your foreign owner or other foreign related parties, you must file. If all transactions were purely with domestic unrelated parties, Form 5472 may not be required for that year.
How detailed must transaction descriptions be?
Provide sufficient detail for the IRS to understand the nature of the transaction. Use clear categories and avoid vague descriptions like “other” without explanation.
