Does a US LLC With No US Income Still Have to File Taxes?

Quick answer: Yes, a foreign-owned single-member LLC must still file Form 5472 along with a simplified Form 1120 annually with the IRS, even if the business has no revenue or activity in the US. This is an information-reporting obligation (not an income tax filing), in effect since 2017. Failing to file on time can result in a minimum penalty of $25,000 per form.

Why File If There’s “No Income”?

Form 5472 isn’t meant to calculate tax — it’s meant to let the IRS track transactions between the LLC and its foreign owner (capital contributions, withdrawals, loans). Even with no transactions, the LLC still needs to file the form with “0” entries to demonstrate compliance.

Other Reporting Obligations to Note

• Form 5472 + simplified Form 1120: Due April 15 of the following year, extendable to October 15
• State maintenance fees: Some states (like California) charge a minimum $800/year fee even with no revenue
• Personal income tax (Form 1040-NR): Only applies if there’s “effectively connected income” (ECI) with a US trade or business

AWE Global provides an annual Form 5472 filing service to ensure your LLC doesn’t get penalized for missing this obligation.
