What is Form 5472 and do you need it?

If you’re an African founder with a Delaware C-Corp, there’s a good chance you’ve wired money from your personal account into your company at some point — to cover early expenses, pay a contractor, or simply keep the lights on. That transaction has a name in the eyes of the IRS: a reportable transaction. And reportable transactions between a US corporation and a foreign related party require Form 5472.

Miss it, and the penalty is $25,000 per unfiled form.

Here’s everything you need to know.

What is Form 5472?

Form 5472 is an IRS information return. It doesn’t calculate tax owed — it reports the existence and nature of transactions between a US corporation and its foreign related parties.

A foreign related party in your case is almost certainly you — the founder. If you’re not a US tax resident and you have a 25% or greater ownership stake in your Delaware C-Corp, you’re a foreign related party.

What counts as a reportable transaction?

Any exchange of money, property, or services between your company and a foreign related party. In practice, this means:

• Capital contributions — money you put into the company from your personal account
• Founder loans — money you lent to the company (or the company lent to you)
• Expense reimbursements — the company paying you back for expenses you covered personally
• Services — if you personally invoiced your own company for work

What does not count: paying a third-party vendor, receiving a salary through payroll, or standard arm’s-length transactions with unrelated parties.

How many forms do you need?

One per transaction type, not per transaction occurrence. If you made three capital contributions throughout the year, that’s one Form 5472 covering all three — because they’re all the same type.

But if you also reimbursed yourself for expenses, that’s a second form. Two foreign founders with different transaction types could each need multiple forms.

When is it due?

Form 5472 is filed alongside your corporate tax return — by April 15 for a Delaware C-Corp. If you file an extension (Form 7004), the 5472 deadline extends with it to October 15.

What happens if you miss it?

The IRS imposes a $25,000 penalty per unfiled form, per year. There’s no sliding scale — it’s $25,000 whether your company made $0 or $500,000. The penalty also applies if the form is filed but incomplete or inaccurate.

This is one of the most disproportionate penalties in the US tax code relative to the complexity of the form itself.

Do you need it if your company had no activity?

Possibly. If you made a capital contribution to incorporate or fund the company — even a small one — that’s a reportable transaction. Many pre-revenue founders assume “no revenue, no filing” and miss this entirely.

The bottom line

If you’re a foreign founder with a Delaware C-Corp and you’ve moved money between yourself and your company for any reason, you almost certainly need Form 5472. The exact number of forms depends on how many types of transactions occurred.
