When a foreign investor asks how to hold a U.S. asset, the most common answer (for individuals, for families, for closely held offshore holdings) is a U.S. limited liability company. The LLC is cheap to form, simple to operate, and creates the limited-liability shield the investor wanted in the first place. What it also creates, since 2017, is one of the most punishing reporting regimes in the U.S. tax code.
What Form 5472 actually is
Form 5472 (Information Return of a 25% Foreign-Owned U.S. Corporation or a Foreign Corporation Engaged in a U.S. Trade or Business) has existed since 1989. What changed in 2017 was that the IRS extended its application to single-member U.S. LLCs that are wholly owned by foreign persons, even though those LLCs are normally disregarded for income tax purposes.
In other words: the LLC owes nothing in U.S. income tax. The LLC still has to file a Form 5472 every year, attached to a pro-forma Form 1120, reporting every reportable transaction between the LLC and its foreign owner or any related party. Capital contributions count. Loans count. Distributions count. Reimbursements count. A single missed transaction is a reportable failure.
The penalty
The civil penalty for failing to file a complete and accurate Form 5472, or for failing to maintain the required records, is $25,000 per form per year. The IRS asserts the penalty without notice in most cases. Late or incomplete filings draw the same penalty. Repeat failures stack.
For a family that holds three rental properties in three single-member LLCs, that is $75,000 a year if all three filings are missed or incomplete. We have seen it.
What gets missed
The most common patterns at the firm:
- Owner believed the LLC had no U.S. tax exposure and therefore no U.S. filing. Half-right. The income tax answer is correct; the reporting answer is not.
- Owner’s home-country accountant prepared the U.S. filings without knowing about Form 5472. Especially common when the owner used an online formation service and never engaged U.S. counsel.
- Capital contributions from the foreign owner to the LLC were treated as informal cash advances. Each one is a reportable transaction.
- The LLC was administratively dissolved. The 5472 still had to be filed for the year the LLC existed.
The EIN requirement
The foreign-owned LLC also needs a U.S. Employer Identification Number, an EIN. The IRS does not issue EINs to applicants without a U.S. taxpayer-identification number unless the application is submitted via fax or mail with Form SS-4, accompanied by a phone-line conversation with the IRS specialty line. The whole process runs four to eight weeks. Owners who try to file Form SS-4 online get rejected at the responsible-party step.
What clean structure looks like
The structure itself is the cheap part. The compliance calendar is the part that costs real attention. For a new foreign-owned U.S. LLC, the first year looks like this:
- Form the LLC and request the EIN within the same month.
- Maintain contemporaneous transfer-pricing documentation for any related-party transaction, no matter how small.
- File the pro-forma Form 1120 with attached Form 5472 by April fifteenth of the following year, or the extended date.
- File the LLC’s state annual report.
- Begin the next year’s logging on the day after the filing.
Year two is the same. Year three is the same. The discipline is the value. The penalty for breaking it is published.
