Question 1
Do you have a US LLC?
General information, not tax advice. Use this checker as a starting point for your own facts.
The rule in plain English
When do foreign-owned LLCs file Form 5472?
The common Form 5472 case is a US single-member LLC that is wholly owned by a non-US person or foreign company and has not elected corporate tax treatment. The IRS treats that LLC as a disregarded entity for income tax purposes, but still requires an information filing when reportable transactions occur.
Reportable transactions are broader than sales revenue. Owner capital contributions, loans, reimbursements, formation costs paid personally, registered-agent fees paid by the owner, and owner draws can all matter even when the LLC had no customers and no profit.
Some paths are different. A multi-member LLC usually starts with partnership filing rules, and an LLC that elected to be taxed as a corporation files through its corporate Form 1120 process. This checker separates those cases so the answer is not forced into a filing sale when the facts point elsewhere.
What are common Form 5472 filing questions?
Who usually needs to file Form 5472?
A foreign-owned US single-member LLC that is treated as a disregarded entity usually files Form 5472 with a pro forma Form 1120 when it has a reportable transaction during the tax year.
Does a dormant LLC with no income still need Form 5472?
Often, yes. No income is different from no reportable transactions, and formation costs, owner contributions, reimbursements, loans, or owner draws can create a filing requirement.
What is the Form 5472 deadline?
For a calendar-year LLC, Form 5472 with the pro forma Form 1120 is generally due April 15. Extensions may be available, but the extension process must be handled correctly.
What happens if Form 5472 is missed?
The IRS penalty is generally $25,000 for a missing or incomplete Form 5472. Late filings can sometimes include a reasonable cause explanation, but the best answer depends on the exact facts.
