Zero Revenue? You Probably Still Must File Form 5472

The single biggest myth among foreign founders is that “no income means no filing.” That is wrong. Form 5472 reports the movement of money between a 25%-foreign-owned US entity and its foreign owner or related parties. The trigger is a reportable transaction during the year — and that has nothing to do with whether the LLC earned a single dollar of revenue.

Consider what happens when you form an LLC. You wire money to open the business bank account. You pay the state formation fee and the registered-agent fee. Each of those is a transaction between you and the LLC. The moment that money moves, you have a reportable transaction, and the duty to file is locked in. For the full list, see what is a reportable transaction.

Capital contributions are explicitly reportable. When you, the non-US owner, put money into the LLC — to fund operations, cover startup costs, or simply seed the bank account — that contribution is reported on Form 5472. There is no minimum-dollar floor. The IRS instructions list contributions and the amounts paid or received between the entity and its related party as reportable.

In practice, only an LLC that moved literally no money all year escapes — and that is exceptionally rare. The deeper dive is on does a dormant LLC need to file Form 5472.

There is a narrow case where a foreign-owned LLC genuinely has no reportable transaction: it was formed in a prior year, never funded, never paid a fee through the owner, and sat completely inert. In that situation, the IRS technical position is that without a reportable transaction there is no Form 5472 filing obligation for that year.

Why you should usually file anyway

The math is brutally one-sided. Filing a dormant return costs you a few hundred dollars at most; getting it wrong costs $25,000. If there is any chance a transaction occurred — and there almost always is — the safe move is to file. The downside of an unnecessary filing is essentially zero; the downside of a missed filing is catastrophic. Estimate the exposure with the penalty calculator.

The filing mechanics are identical whether the LLC made $0 or $1 million. A foreign-owned disregarded entity attaches Form 5472 to a pro forma Form 1120 — only the top identifying information and the Form 5472 are completed, not a full corporate tax return. There is no electronic path; the disregarded-entity-as- corporation rule under T.D. 9796 (effective for tax years beginning on or after January 1, 2017) requires paper or fax submission.

A dormant LLC gets no special grace period. The deadline is the 15th day of the 4th month after the tax year ends — April 15 for a calendar-year LLC. A timely Form 7004 pushes the filing deadline to October 15. Because a disregarded entity owes no entity-level tax, the extension only extends the time to file, never a payment. Missing April 15 without an extension exposes you immediately to the $25,000 penalty.

The penalty does not care that your LLC made no money. It is a flat $25,000 assessment for failing to file a required Form 5472, and it applies per form, per year. Because there is no statute of limitations on an unfiled information return, the IRS can assess a year you missed long ago. If you ignore a 90-day notice, the penalty escalates by another $25,000 for each 30-day period.

This is one of the harshest information-return penalties in the code. Read the full rule on the statute of limitations post.

Founders often confuse two unrelated obligations. Beneficial Ownership Information (BOI) reporting to FinCEN and Form 5472 reporting to the IRS are completely different. As of the March 2025 interim final rule, domestically formed entities — which includes a foreign-owned US LLC — are exempt from BOI; the rule now applies only to foreign reporting companies. That exemption does not touch Form 5472, which the IRS still requires for a dormant foreign-owned LLC with a reportable transaction.

In short: you can likely skip BOI but you still owe Form 5472. Compare your options on the pricing page.

A dormant filing is no cheaper to skip and no more expensive to do right. For a flat $299, form5472.tax prepares Form 5472 and the pro forma Form 1120, confirms your reportable transactions, and files it by mail or fax — saving $248 versus form5472.online and well over $1,700 versus doola.
