Form 5472 and pro forma Form 1120

A foreign-owned U.S. disregarded entity can have a federal information-return duty even when the owner believes there is “no tax to pay”. Filing and tax payment are different questions.

Who may be affected?

IRS instructions cover a foreign-owned U.S. disregarded entity with reportable transactions involving a foreign owner or related party. A common example is a single-member LLC owned by a foreign person or entity and treated as disregarded for federal purposes, unless another tax election has been made.

What can be a reportable transaction?

The scope is broader than ordinary sales. It can include owner contributions, distributions, expense payments, loans, transfers of assets and other transactions with the owner or a related party. Even a company viewed as “inactive” may have reportable transactions if the owner funded its costs.

Why a pro forma Form 1120?

Form 5472 for a foreign-owned U.S. DE is filed with a pro forma Form 1120 in the manner described by the IRS. This does not automatically mean the company is taxed as an ordinary C corporation; it is the technical filing mechanism for the information return.

Penalty

USD 25,000The IRS states a USD 25,000 penalty for failing to file Form 5472 on time and in the required manner. Continued failure after notice can lead to additional penalties. The figure should not be used without explaining when the duty actually applies.

Build an annual workflow

  1. confirm the LLC’s federal classification;
  2. identify the foreign owner and related parties;
  3. record owner-company flows throughout the year;
  4. keep personal and company spending separate;
  5. deliver complete data to the adviser early;
  6. retain filing evidence and copies.

Records to prepare for the tax preparer

Go Solutions can provide a calendar, checklist and data coordination. Tax analysis of transactions, return preparation, signature and filing are outside the Go Solutions service. They are performed by the appropriate tax adviser or return preparer under a separate engagement.

Build the workflow before the deadline

Annual Compliance Care can include the calendar, reminders and adviser-data coordination. It does not replace individual tax advice.
