Should you use Form 5472 Desk?
A strict fit checker before you spend time preparing a high-risk IRS information return packet.
TL;DR
All answers must be yes. One no means the case should stop before payment and move to official IRS guidance or a qualified U.S. tax professional.
The first MVP lane is intentionally narrow because Form 5472 has high penalty and support risk. The checker disqualifies early instead of exposing complex tax questions in the interface.
A positive checker result is not tax advice. It only means the facts appear to match the software packet lane.
1.Does one foreign individual directly own 100% of the LLC?
2.Is it a U.S. single-member LLC treated as a disregarded entity?
3.Is this the current 2025 calendar-year filing, on time or protected by timely Form 7004?
4.Do you already have the EIN, owner identity/reference facts, formation records, and transaction support?
5.Was there zero income and only simple owner contributions, owner distributions, or zero activity?
6.No treaty, ECI, transfer pricing, IRS notice, penalty, reasonable-cause, or representation issue?
Answer every hard-stop question.
This product should not prepare a packet until all scope gates are confirmed.
Four possible checker outputs
Clean supported lane
Foreign individual, 100% U.S. single-member LLC, disregarded entity, EIN ready, current 2025 calendar year, zero income, and simple owner capital activity.
Identity or records not ready
Missing EIN, owner ID/reference facts, formation records, address, or transaction support should stop before packet preparation.
Professional judgment needed
Ownership chains, income, ECI, treaty, transfer pricing, classification, complex transactions, and notices need official or professional review.

What the checker is looking for
The checker looks for a clean foreign-owned U.S. disregarded entity packet: one foreign individual owner, one U.S. single-member LLC, current calendar-year timing, ready identity records, and only simple owner capital activity.
It does not decide whether a filing is required in ambiguous cases. It decides whether this software should continue.
Official sources and assumptions
This checker uses official instructions to expose fit questions, source records, and hard stops for a narrow self-preparation packet. If a fact falls outside the supported answers, use the linked official source before continuing.
