Single-Member LLC
Tax Return Filing

Yes. Even if your Single-Member LLC had zero transactions, zero revenue, or zero profits, you are still legally required by the IRS to file Form 5472 and a pro-forma Form 1120 to report the foreign ownership and any related party transactions (like initial capital contribution).

Form 5472 is an informational return used to report transactions between a US LLC (treated as a disregarded entity) and its foreign owner. The IRS uses this to prevent tax evasion and track foreign investment in the US. Failing to file it results in a mandatory $25,000 penalty.

For calendar year LLCs (which most are), the filing deadline for Form 1120 and Form 5472 is April 15th of the following year. You can request a 6-month extension by filing Form 7004 before the original deadline.

If you are a non-US resident, perform all work outside the US, and have no US physical presence (no employees, offices, or warehouse), your income is typically classified as 'Not Effectively Connected Income' (ETBUS). In this case, you do not owe US federal income tax, but you still must file the informational returns.

Single-Member LLCs owned by non-US residents cannot e-file Form 1120 and 5472 directly through standard consumer software. These forms must be faxed or mailed to the IRS. We handle the preparation and dedicated IRS fax submission for you.

We need your LLC's EIN confirmation letter (CP 575 or 147C), your Articles of Organization, a basic summary of income and expenses (or bank statements), and your personal identification details. We'll provide a simple questionnaire for you to complete.

If you missed the deadline, you are exposed to the $25,000 late filing penalty. However, there are IRS penalty abatement procedures and first-time penalty waivers we can apply for. It is critical to get compliant immediately rather than waiting.

This service covers the federal IRS tax return (Forms 1120 & 5472). If your LLC is registered in a state like Wyoming or Delaware, there is no state income tax return required, though Wyoming requires an annual franchise report which is separate.

No. You do not need a personal ITIN to file Forms 1120 and 5472 for your Single-Member LLC. We can file these forms using your company's EIN and the foreign owner's foreign tax ID.

Once we receive your completed questionnaire and documents, our CPAs prepare the draft returns within 3 to 5 business days for your review and signature. Once signed, we immediately submit them to the IRS.
