Form 5472 guide
Form 5472: what foreign founders need to know.
If you're a non-US founder with a US entity, the IRS may require you to file Form 5472 — and the penalties for missing it are steep.
An IRS filing you can't afford to miss.
Form 5472 is an IRS information return filed by a "reporting corporation" that has "reportable transactions" with a related party. Under the IRS's current instructions, a reporting corporation is either a 25%-foreign-owned US corporation or a foreign corporation engaged in a US trade or business.
There's a narrower third case: a foreign-owned US disregarded entity — for example, a single-member US LLC wholly owned by one foreign person — is treated as a corporation only for the limited section 6038A reporting rules, and files its Form 5472 attached to a pro forma Form 1120. That means a US LLC is not automatically in scope just because a foreign person owns 25%. How the entity is taxed changes the analysis.
In practice, many US companies owned by a non-US founder find this applies to them. If you're from India, Nigeria, the UK, Brazil — anywhere outside the US — and you own a US entity, it's worth checking whether this applies to you.
"Reportable transactions" can include capital contributions, loans, paying yourself, or providing services to your US entity from abroad — there's no minimum transaction size that automatically exempts you.
Whether it applies to you comes down to what kind of entity you have and whether there are reportable transactions — which we break down step by step in who must file Form 5472.
The penalty is real — and it can add up.
The IRS treats a Form 5472 that is not filed, filed late, or substantially incomplete as a failure to file, and a separate Form 5472 is due for each related party you transact with. If a failure continues after the IRS notifies you, additional penalties can apply on top of the initial one. Confirm the current penalty amount and filing rules with a tax professional or directly on irs.gov — don't rely on a number from a marketing page, including this one.
Common mistakes
What founders get wrong.
- 01
Not knowing it exists
Many founders discover Form 5472 only when their tax preparer asks about it, or after a filing deadline has already passed.
- 02
Thinking it only applies to large companies
There's no revenue threshold. If your US entity has a foreign owner and reportable transactions, filing can be required even if the company earned nothing that year.
- 03
Filing late or incompletely
The IRS treats a substantially incomplete filing as a failure to file, and a separate Form 5472 is due for each related party. This is not a form to guess at.
- 04
Using a tax preparer who doesn't know international rules
Not every US accountant is familiar with Form 5472. It requires specific knowledge of foreign-owned entity reporting — ask before you hire one.
What to do about it
Talk to a tax professional.
- 01
This isn't something Corppy files for you
Form 5472 is a tax filing, not a formation task, and it isn't part of what Corppy handles. Don't assume it's covered because your formation is — confirm who's responsible for it.
- 02
Find a preparer with international experience
Look specifically for a CPA or tax attorney who has handled foreign-owned entity reporting before, not just general small-business taxes.
- 03
Ask early, not at tax season
Talk to a tax professional soon after you form your entity about whether you need to file, and get the deadline on your calendar before it's urgent.
The two questions everyone asks.
Once you know the form applies, two questions follow: when it's due, and what it costs to get wrong. We don't print those numbers — they change, and they belong on the primary source. Instead, we've written walkthroughs for finding the current answer yourself.
