Foreign-owned single-member LLC: Form 5472 and the records behind it

A single-member LLC is usually ignored for income tax purposes. For a foreign owner, the IRS treats a U.S. LLC as a corporation for the limited purpose of reporting transactions with its owner. The LLC must file Form 5472 to report those transactions, even if it earns nothing.

Form 5472 reports reportable transactions between the LLC and its foreign owner or related parties. Examples are capital contributions, loans in either direction, payments for services, interest, and sales of goods or property. The form lists each category with the amounts.

The form is attached to a pro forma Form 1120 and filed with the IRS following the instructions for foreign-owned disregarded entities. Filing electronically may not be available for these forms, so check the current rules. Ask a tax professional who prepares them regularly.

The deadline generally follows the return due date, with an extension available through Form 7004. The penalty for failing to file, or for filing a form that is incomplete or incorrect, starts at $25,000 per form. That is a very high price for an administrative mistake, which is why founders should not wait.

Keep a ledger of every transaction between the LLC and the owner: when, how much, and what for. Keep the bank statements that show the movements. Record owner funding as a capital contribution or a loan, with documents. When the books show that clearly, the form takes minutes to prepare. When they do not, it may take a reconstruction.

A foreign owner may have additional tax filings in the U.S. and at home. Ask a tax professional with international experience to review the whole picture, not only this form.

The rule applies when a single-member LLC is wholly owned by a foreign person, whether an individual or a company. If the LLC has two owners, it is treated as a partnership and the analysis changes. The form is about the relationship between the LLC and its owner, so a founder who lives abroad and owns a Delaware LLC alone is the typical case.

In one year, a founder wires $20,000 to open the LLC's bank account and lends the LLC another $5,000. Later, the LLC repays $2,000 of that loan and pays the founder $3,000 for consulting work. Each of those four movements is a reportable transaction. If the bookkeeping records them as one lump called owner funding, the preparer has to take them apart. A ledger that separates contributions, loans, repayments, and payments for services makes the form a short task.

File as soon as you find out, include a statement explaining why the form was late, and ask for penalty relief. Contacting the IRS before it contacts you generally helps. A professional who handles these forms regularly can tell you what to include.
