Foreign-Owned U.S. Businesses
A U.S. business with a non-U.S. owner has reporting obligations that apply even in a year with no income. A foreign-owned single-member LLC must file Form 5472 with a pro forma Form 1120, and the penalty for missing it is substantial and applies per year. Blue Sage handles the full compliance picture.
What's included
- Form 5472 and pro forma Form 1120 for foreign-owned single-member LLCs
- Corporate and partnership returns with foreign ownership
- EIN applications for entities without a U.S. responsible party
- ITIN applications and renewals for foreign owners
- Withholding obligations on payments to foreign persons
- Effectively connected income analysis
- Treaty position review and disclosure
- State registration and filing where the business has nexus
Who this is for
Non-U.S. residents who formed a U.S. LLC or corporation, often to sell into the U.S. market or hold property, and were told it was a simple structure. It usually is simple to form and considerably less simple to keep compliant.
It is also for foreign owners who have been operating for a few years without filing anything, on the understanding that no U.S. income meant no U.S. obligation. That is not how the reporting rules work, and the penalties accumulate per year.

|---|---|
| Foreign-owned single-member LLC | Must file Form 5472 with a pro forma Form 1120, even with no income and no activity beyond formation |
| Reportable transactions | Includes capital contributions and distributions between the LLC and its owner, not just sales |
| Form 5472 penalty | Substantial per form, per year, and it applies to a late filing as well as a missing one |
| EIN | Required. Obtainable without a U.S. Social Security number, though the process differs. |
| ITIN | Often needed for the foreign owner to file personally or claim treaty benefits |

Questions
Does a foreign-owned LLC with no income still have to file?
Yes. A foreign-owned single-member LLC must file Form 5472 together with a pro forma Form 1120 for any year in which it had a reportable transaction, and capital contributions from the owner count as reportable transactions. A year with no revenue is still very often a year with a filing requirement.
What is the penalty for missing Form 5472?
It is substantial, charged per form per year, and it applies to a late or incomplete filing as well as a missing one. Because it accrues separately for each year, a business that has been unaware of the requirement for several years can face a large cumulative exposure. Reasonable cause relief is sometimes available.
Can I get an EIN without a U.S. Social Security number?
Yes. An entity with no U.S. responsible party holding a Social Security number can still obtain an EIN, though the application route differs from the standard online process and takes longer. It is a required first step before the entity can file anything or open a U.S. bank account.
