Form 5472 filing support
Confirm whether the filing applies, assemble the related-party transaction record and coordinate Form 5472 with the correct US return package.
Who this service is for.
Form 5472 can apply to a 25% foreign-owned US corporation or a foreign corporation engaged in a US trade or business when it has a reportable transaction with a related party. A wholly foreign-owned US disregarded entity can also be a reporting corporation for this purpose.
A single-member LLC is not automatically the same filing case as a C-Corp, partnership or LLC that elected a different tax classification. We confirm the entity classification, ownership and transactions before defining the work. The IRS instructions also contain exceptions, including where the reporting corporation had no transactions of the specified types.

No revenue does not settle the question.
The Form 5472 instructions treat certain amounts connected with formation, dissolution, acquisition or disposition—including owner contributions and distributions—as reportable transactions for a foreign-owned US disregarded entity. A company can therefore have no customer revenue and still need a transaction review. Conversely, the foreign-owned label alone does not remove the need to test the IRS exceptions and the company's tax classification.
For an applicable foreign-owned US disregarded entity, Form 5472 is attached to a pro forma Form 1120 used for this limited reporting requirement. It is not the same as preparing a complete corporation income-tax return. The IRS currently directs these filings through its dedicated fax or mail procedure rather than electronic filing. We confirm the current IRS delivery instructions for each engagement.

Responsibilities, fee basis and timing.
Before work begins, the proposal identifies the year, entity, related parties, included forms, preparer or reviewer responsibility, filing coordination and what evidence will be retained. Fees are quoted after reviewing classification, number of related parties, transaction volume, record condition, prior years and any IRS notice. A straightforward current-year filing and a multi-year remediation are not priced as the same job.
The deadline follows the due date of the applicable income-tax return, including a valid extension. A calendar-year corporation generally uses the fourth-month rule in the Form 1120 instructions, but exceptions and tax-year facts matter. A Form 7004 extension must be requested by the regular due date. We do not guarantee an extension, penalty relief, acceptance of incomplete records or an IRS processing outcome.
The IRS instructions state a $25,000 penalty for failing to file Form 5472 when due and in the prescribed manner, with additional penalties possible after an IRS notice if the failure continues. Filing a substantially incomplete form can also be treated as a failure. Those rules make an accurate applicability and transaction review more important than submitting a generic form.
Common questions.
Does every foreign-owned LLC file Form 5472?
No. The company's US tax classification, ownership and reportable transactions matter. We review the facts against the current IRS instructions and their exceptions.
Is the pro forma Form 1120 a normal C-Corp return?
No. For a foreign-owned US disregarded entity, the IRS describes a limited pro forma Form 1120 to which Form 5472 is attached. A corporation or an LLC with another classification can have a different return package.
Can more than one Form 5472 be required?
Yes. The IRS instructions call for a separate Form 5472 for each related party with which the reporting corporation had reportable transactions.
Is filing proof included?
The proposal states the filing method, handoff and evidence included. We do not describe a submission as complete until the agreed delivery step and proof have been recorded.
Is this filing included in every annual package?
No. Package and tax-return inclusions are confirmed in the written scope. Use the pricing page to compare packages, then confirm the entity-specific filing list in your proposal.
