My US LLC Had No Income. Do I Still Have to File?

A US LLC that never made a sale still has a federal paperwork obligation. Here's what foreign-owned, single-member LLCs actually need to file each year, even at zero revenue.

The short answer

Yes. If your US LLC is owned by a non-US person (or a foreign company) and has no other owners, the IRS treats it as a 'disregarded entity' for tax purposes, but that does not mean it is disregarded for reporting purposes. Even if the LLC had zero income, zero sales, and zero activity all year, you are still required to file Form 5472 alongside a pro-forma Form 1120. This applies whether the LLC is dormant, pre-revenue, or simply used to hold an asset, a domain, or a bank account.

This is one of the most misunderstood parts of running a US company from abroad. Founders assume that 'no income' means 'nothing to file.' In the US, income tax and information reporting are two separate systems, and the second one applies to you regardless of profit.

Why 'no income' doesn't mean 'no filing'

Form 5472 is not a tax return. It is an information return the IRS uses to see the transactions between your LLC and its foreign owner. The IRS wants visibility into money moving between you and your company, capital you put in, distributions you took out, loans, or expenses paid on the LLC's behalf, even when none of that activity is taxable income. The pro-forma Form 1120 is attached purely as a cover sheet to give the 5472 a return to sit on. You leave most of the income fields blank or at zero, but the form still has to exist and be filed correctly.

So the filing requirement is tied to ownership structure (a foreign person owning a US disregarded entity), not to whether the business generated revenue.

What counts as a 'reportable transaction'

Many first-time filers assume that if there was no revenue there were no transactions. In practice, almost every LLC has at least one reportable transaction in its first year. Common examples include:

• The founder funding the LLC's bank account to cover formation costs or a card deposit
• The LLC paying its registered agent, formation, or banking fees
• The founder paying for LLC expenses personally and later reimbursing themselves
• Any transfer between the founder and the LLC in either direction, even small amounts

If genuinely nothing happened, not even a funding transfer, you may still need to file a 5472 showing no reportable transactions, because the requirement is triggered by the ownership relationship itself, not only by activity. This is exactly the kind of judgment call worth getting right with an accountant familiar with foreign-owned LLCs rather than guessing.

Deadlines and penalties

The pro-forma 1120 with Form 5472 attached is generally due by the 15th day of the fourth month after the LLC's tax year ends, April 15 for a calendar-year LLC. You can file Form 7004 for a six-month extension, pushing the deadline to around October 15. The forms must be mailed or faxed to the IRS since disregarded entities generally cannot e-file this combination.

The penalty for failing to file, or filing an incomplete or inaccurate Form 5472, is 25,000 dollars per form, per year. This is not a scaled or income-based penalty. It applies whether your LLC made one dollar or zero dollars, and it applies even if you genuinely didn't know the rule existed. The IRS can also extend the penalty if the failure continues after being notified.

The 25,000 dollar penalty exists specifically because this is an information return, not an income tax bill. The IRS is penalizing missing visibility, not unpaid tax.

What you need before you can file

To file Form 5472 and the pro-forma 1120, your LLC needs an EIN (Employer Identification Number) issued by the IRS. Note that an EIN is different from an ITIN. An EIN identifies the business, and non-US founders can get one without a visa or an SSN, typically via Form SS-4 by fax or mail since the IRS's online EIN tool is not available to applicants without a US taxpayer number. An ITIN, on the other hand, identifies an individual person for tax purposes and is only relevant if you personally need to file a US return, for example a Form 1040-NR because you have US-source income taxed to you directly. Most founders filing 5472 for a dormant LLC do not need an ITIN at all, just the LLC's EIN.

A simple compliance checklist

Wyoming remains one of the most common states for this structure because of its low annual fees and straightforward maintenance, but the federal filing requirement above is identical no matter which state you form in.

How this fits into ongoing compliance

Getting the LLC formed and the bank account open is only the first stage. The recurring parts, annual state reports, the EIN, and this federal information return, are what actually keep the company compliant year over year. This is the piece founders most often forget because it doesn't show up as a bill or a login reminder, it's simply a filing obligation that exists quietly in the background. Founders Credit sets clients up with the LLC, EIN, ITIN if needed, and a US bank account and card remotely, and flags this exact filing requirement so it doesn't get missed in year one.

Glossary

• Disregarded entity: A single-member LLC that the IRS ignores for income tax purposes, treating its income as the owner's, while still requiring separate information reporting when the owner is foreign.
• Form 5472: An IRS information return reporting transactions between a US entity and its foreign owner, required annually regardless of income.
• Pro-forma Form 1120: A mostly blank corporate tax return filed purely as a cover document so Form 5472 has a return to attach to.
• EIN: Employer Identification Number, the business's federal tax ID, required before you can file 5472 or open a US bank account.
• ITIN: Individual Taxpayer Identification Number, used by people ineligible for a Social Security Number who need to file personal US tax returns.
