Summary

For a foreign-owned U.S. disregarded entity, the foreign owner is usually the related party in the simple supported lane. Part V asks for amounts connected with formation, dissolution, acquisition, disposition, contributions, and distributions. Form 5472 Desk supports zero activity or simple owner contributions/distributions only; loans, services, rents, royalties, IP, assets, nonmonetary transfers, and transfer pricing stop.

Part V owner-capital activity is supported only when it stays simple and records are ready.

Related party in the supported case

The IRS definition of related party is broad. The product deliberately narrows that concept to a clean fact pattern: one foreign individual directly owns 100% of the domestic single-member LLC treated as disregarded.

Part V in plain English

Part V is the foreign-owned U.S. DE section for amounts paid or received in connection with formation, dissolution, acquisition, disposition, contributions, and distributions. The product can organize simple owner capital amounts when the records are ready.

Transactions that stop the workflow

Stop for sales, services, commissions, rents, royalties, premiums, insurance, loans, interest, IP, asset transfers, debt instruments, cost-sharing arrangements, nonmonetary transfers, less-than-full-consideration transactions, or any section 482 transfer-pricing analysis.

What this tool prepares

Form 5472 Desk turns clean user-entered Part V facts into a self-review packet and checklist. It does not classify ambiguous transactions, value property, draft transfer-pricing support, or decide whether an unusual transfer is reportable.
