Form 5472: the return that costs $25,000 to forget

Of everything we deal with for founders outside the United States, this is the one that produces the worst outcomes, and it is almost always because nobody in the chain had a reason to mention it.

The rule is straightforward. If a foreign person owns twenty five percent or more of a US entity, that entity must file Form 5472 each year, accompanied by a pro forma Form 1120. The penalty for failing to file begins at twenty five thousand dollars per return, per year.

The part that catches people

It is due whether or not the company earned anything.

This is not how people expect tax filings to work. The reasonable assumption, and it is reasonable, is that a company with no income has nothing to file. That holds for a domestic single member LLC with a US owner. It does not hold here, because Form 5472 is not an income tax return. It is an information return about transactions between a US entity and its foreign related parties, and the obligation attaches to the ownership structure rather than to the profit.

Why your formation provider did not tell you

Not, usually, because they were hiding it. Because they had no reason to know it applied to you and no obligation to look.

A formation service files a document with a state. Its relationship with you is designed to end when the certificate is issued. It does not prepare tax returns, it does not know your ownership percentages in the way a preparer would, and it has no touchpoint with you eleven months later when the return falls due.

This is the specific failure that comes from splitting formation and accounting between two firms, and it is the reason we built the practice the other way round. When the people who chose the entity are the people who will file the return, the return is visible from the beginning.

What actually gets filed

Two documents that travel together. Form 5472 itself, reporting the foreign related parties and the reportable transactions with them. And a Form 1120 filled in only to the extent needed to carry the 5472, which is why it is called pro forma. For a disregarded entity, the 1120 is largely a cover sheet.

Because the filing is a paper attachment rather than a straightforward electronic return, it has its own submission requirements and its own opportunities to go wrong. A return sent to the wrong address, or without the correct notation, can be treated as not filed.

If you are already late

Read this part before you panic, because the situation is usually better than it first appears.

The penalty is significant but it is not the end of the analysis. Reasonable cause relief exists. Coming forward voluntarily, before any contact from the IRS, is a materially better position than being found. And in a great many cases the underlying tax owed is zero, which affects how the matter is viewed even though it does not remove the filing requirement.

What makes it worse is time and silence. Each year that passes is another return and another penalty exposure, and a taxpayer who was contacted first has fewer options than one who came forward.

• Work out which years are open, which usually means every year since formation.
• Prepare the returns for all of them, oldest first, rather than starting with the current year and hoping the rest are forgotten.
• Assemble the reasonable cause facts honestly. Not being told by a formation service is a real fact pattern and it is common.
• File, then put the recurring deadline in a calendar that is not your memory.

Does this mean I owe US tax?

Separate question, and the answer is frequently no.

Whether you owe US income tax depends on whether your income is effectively connected with a US trade or business, and on any treaty between the United States and where you live. A single member LLC owned by a non resident, with no US office, no US employees and no dependent agent acting in the US, often has no US income tax liability at all.

That conclusion has to be reached on your facts rather than assumed from a forum post. But it is worth understanding that the filing obligation and the tax liability are two different things, and that people frequently conflate them in both directions: assuming they owe tax when they do not, and assuming they need not file because they owe nothing.
