Single-member LLC

A US-organized LLC with one member is generally disregarded from its owner for federal income tax unless an effective corporate election applies. The LLC still exists as a business; its income-tax activity is generally reported through the owner.

This default classification does not depend on whether the owner lives in the US or abroad, and it does not eliminate all filings. Employment tax and certain excise taxes can treat the LLC separately. Wholly foreign-owned status can also bring the Form 5472 reporting described below.

An individual owner uses the return and schedules appropriate to their tax status and the LLC’s activities. For owners filing Form 1040 or 1040-SR, common examples are Schedule C for business, Schedule E for relevant rental or other activities, and Schedule F for farming. Not every LLC uses Schedule C, and these three schedules are not a package to file together.

If the owner is a corporation or partnership, the LLC’s activity is generally treated as part of that owner’s business under its applicable federal income-tax reporting rules. An individual’s Schedule C is not the default. If the owner is itself an LLC, establish its tax classification as well.

Foreign individual and entity owners also need to determine their own US income-tax filings from the activities, income and applicable rules. Form 5472 for the LLC does not complete those filings. Having no US customers does not by itself settle the obligation.

Keep the LLC’s income, expenses, assets and owner transactions clearly recorded for whoever prepares the owner’s return. Individual business owners should also check self-employment tax and estimated payments. Tax does not become relevant only when money is transferred out to the owner.

This section and the Form 5472 procedures below apply only to a US-organized entity wholly owned by one foreign person and disregarded from that owner for federal income tax. A single-member LLC without an effective corporate election is a common example.

The LLC’s income-tax activity normally follows its owner, which may be an individual or a foreign entity. The entity’s Form 5472 information reporting and the owner’s US income-tax duties are separate. Neither having no US customers nor making no transfers to yourself settles the answer.

Prepare a schedule of dealings with the owner and other related parties: dates, counterparties, amounts and currencies, purpose, payer, recipient and contracts, invoices, transfers or evidence of expenses paid on the business’s behalf.

Include contributions, loans, repayments, distributions, and relevant formation or dissolution transactions even when they are not sales revenue. For example, a startup-capital contribution still needs review even if the business had no customers in its first year.

1. Complete Form 5472 under the current instructions. Generally, prepare a separate form for each related party with reportable transactions.
2. Prepare the pro forma Form 1120. Current instructions require the entity’s name and address and page-one items B and E, with “Foreign-owned U.S. DE” across the top. Item B is the EIN; complete item E for the facts and current form.
3. Include required statements, particularly for Part V transactions not already covered in Part IV. Keeping them only in the private books is not enough.
4. Review the name, EIN, year, related parties, amounts, attachments and form versions, and retain an exact copy of what is submitted.

The IRS instructions checked for this guide do not permit these entities to e-file Form 5472. The required submission methods are below; reopen the current instructions before acting.

Do not use the ordinary Form 1120 address or apply this special procedure to a regular C corporation. Successful transmission or delivery is evidence of sending, not a review of the return’s correctness.

The entity uses its owner’s US tax-reporting year or, if there is none, the calendar year. Form 5472 is due with the pro forma Form 1120, including a valid extension.

To request an extension, submit Form 7004 by the regular deadline. Use the Form 1120 code on Part I, line 1, write “Foreign-owned U.S. DE” across the top, and use the prescribed fax or mail procedure in the 5472 instructions. Do not rely only on ordinary Form 7004 e-filing or address rules.

Failure to file properly, substantially incomplete reporting or failure to retain required records can trigger a $25,000 penalty, with further penalties for a continuing failure. Seek specialist review promptly if an earlier year may have been missed.
