Reportable Transaction Checker: Did Your LLC Have One?

The entire Form 5472 filing obligation turns on this one concept. A reportable transaction is any transfer of value — in either direction — between your US LLC and a related party, most commonly you, the owner. It is deliberately broad: the IRS wants to see every dealing between the company and the foreign people or entities connected to it.

The full catalogue is on the reportable transaction page. The checker above turns that list into 12 plain-English questions.

This is the trap that catches the most founders. You form the LLC, open a US bank account, and wire in some money to get started. That wire is a capital contribution from you — a related party — to the company. It is a textbook reportable transaction, and it happens to virtually every LLC on day one.

Because funding is nearly universal, the practical answer to “did I have a reportable transaction?” is almost always yes, even for a company that never earned a cent. That is the reasoning behind the site-wide guidance that virtually every foreign-owned SMLLC has at least one reportable transaction and therefore must file. Confirm your specific case with the 60-second qualifier.

“We made no money, so we don’t file” is the single most expensive misconception about Form 5472. The form is an information return, not a tax return. Its trigger is a reportable transaction with a related party — and that has nothing to do with whether the company was profitable, broke even, or lost money.

The full dormant-LLC analysis is on the dormant LLC page. Short version: a truly dormant LLC with no money movement at all may not file for that year, but that situation is rare.

Founders often pay the LLC’s setup costs personally before the company even has a bank account — the state filing fee, the registered-agent fee, perhaps an EIN service. Each of those is money you, a related party, spent on behalf of the LLC. That is a reportable transaction, even though it feels like a trivial startup expense.

This matters because it means a company can have a reportable transaction before it ever opens a bank account or earns a dollar. If you paid anything to bring the LLC into existence, you have very likely already crossed the threshold into “must file.”

It is just as important not to over-report. The reportable-transaction rule applies only to dealings with related parties— you, companies you own or control, and people or entities attributed to you. Ordinary arm’s-length business with unrelated third parties stays off Form 5472, even though those payments are real business expenses.

The checker’s questions are written around related parties for exactly this reason — a busy store with hundreds of unrelated customer transactions might still have only onereportable transaction (the owner’s funding), which is enough to require filing.

There is a genuine exemption, but it is narrow. If, for an entire tax year, your LLC had no reportable transaction with any related party — nothing funded, no fees paid on its behalf, no loans, no distributions, no related-company dealings — then there is nothing to report and no Form 5472 is required for that year.

The catch is that this almost never describes a real LLC, especially a new one. The act of forming and funding it usually creates a transaction. Even a “dormant” company often has a small fee paid by the owner. So while the all-no result on the checker is possible, treat it as a prompt to double-check, not a definitive clearance. Message us and we’ll confirm for free before you decide to skip a year.

The consequence of guessing wrong is steep. If your LLC had a reportable transaction and you did not file, the IRS can assess a flat $25,000 penalty for each unfiled Form 5472, for each year, with no maximum and no time limit. After a 90-day notice, an additional $25,000 accrues every 30 days the form stays unfiled.

That asymmetry is why the conservative reading is correct: the cost of needlessly filing when you might have been exempt is the modest filing fee; the cost of skipping when you actually owed the form is $25,000. Read the full mechanics on the penalty page and estimate exposure with the penalty calculator.

Once the checker tells you that you have a reportable transaction, the next question is where it belongs on the form. Form 5472 groups transactions into parts by type. You report by category and total amount, not transaction by transaction.

The line-by-line walkthrough is on the Form 5472 instructions page, and a filled illustration is on the example page. We assign every transaction to the correct part as part of the flat $299 filing.

Several checker questions cover different related parties: you, a company you own, a family member, an offshore account. If you answered “yes” for transactions with more than one related party, you do not file one combined form — you file a separate Form 5472 for each related party, all attached to a single pro forma Form 1120.

That multiplies the penalty exposure too: the $25,000 is per form, so three related parties means three forms and up to $75,000 at risk for a single unfiled year. Count your related parties before estimating exposure — the penalty calculator assumes one form per year, so multiply accordingly.

A “yes” result points to a clear next step. You prepare Form 5472, complete the identifying lines of a pro forma Form 1120 to carry it, and file the package the only two ways the IRS accepts for a disregarded entity: mail or fax. There is no e-file path. Keep the certified-mail receipt or fax confirmation as proof of timely filing.

The full process is on how to file Form 5472. Or skip the paperwork: we prepare and file it for a flat $299 — start on the apply page.

The checker is built to make a complex rule approachable, but it cannot see your full facts the way a specialist reviewing your records can. Treat a result as a strong signal, not a final ruling — particularly an all-no result, where the stakes of being wrong are a $25,000 penalty.

The guiding principle throughout Form 5472 is asymmetry: filing when you might not have needed to costs a modest fee, while skipping when you did need to costs $25,000. When in doubt, file — or message us and we will confirm your situation for free before you decide. We file correctly for a flat $299.

The checker is intentionally conservative, and that conservatism is grounded in the actual rules rather than a sales pitch. The definition of a reportable transaction is broad, the act of funding an LLC almost always satisfies it, and the penalty for guessing wrong is severe and uncapped. Put together, the accurate default for a foreign-owned LLC is that it must file.

That is not the same as “everyone must file no matter what.” A truly dormant LLC with zero money movement can be exempt for a year. But those cases are uncommon, and they are exactly the borderline situations worth confirming with a specialist. For the typical founder who funded their LLC and paid a fee or two, the checker — and the law — point clearly to filing.
