Roughly every foreign-owned single-member US LLC owes Form 5472, and the penalty for skipping it starts at $25,000. That figure surprises most non-resident founders, because they assume a one-owner LLC with modest revenue has nothing to report. The form itself is short, but the IRS rules around who files it, what counts as a reportable transaction, and how it attaches to a separate return are easy to get wrong. Here are the Form 5472 instructions translated into plain steps for owners who do not live in the United States.
Form 5472 is an IRS information return titled "Information Return of a 25% Foreign-Owned U.S. Corporation or a Foreign Corporation Engaged in a U.S. Trade or Business." A foreign-owned single-member US LLC must file it whenever it is treated as a disregarded entity for US tax purposes and has at least one reportable transaction with a related party during the tax year. In practice, almost every Wyoming LLC owned by one non-resident falls into this group.
The form exists so the IRS can see money moving between a US entity and its foreign owner or affiliates. It does not calculate tax. It reports relationships and transactions. A "reporting corporation" in the form's language includes a single-member LLC owned by a non-US person, even though the LLC is not itself a corporation, because the IRS regulations under sections 6038A and 6038C extend the requirement to these disregarded entities.
The trigger word is "related party." That means the foreign owner, plus any company or person connected to that owner by ownership or control. If you sent money from your own pocket into the LLC, or the LLC paid you back, or you loaned it funds, those are reportable transactions between you and the entity. A brand new LLC with a single capital contribution from its owner already has a reportable transaction, so the filing obligation exists from year one.
Two points clear up most of the confusion. First, the LLC being "disregarded" for income tax does not make it disregarded for this information return. The IRS specifically treats a foreign-owned disregarded LLC as a reporting corporation for Form 5472 purposes, so the entity that pays no separate income tax can still owe the form. Second, "25% foreign-owned" in the title sounds like a high bar, but a single-member LLC owned entirely by one non-resident is 100% foreign-owned, which clears that threshold comfortably.
A reportable transaction is any monetary or non-monetary exchange between the US LLC and a related party, including the owner. Many founders wrongly believe only sales or invoices count. The IRS instructions list a much wider set, and for a disregarded entity even contributions and distributions of capital are reportable.
Each category has its own line on the form where you enter a total. You report the type and dollar amount of the transactions, converted to US dollars. You are describing the flow of value between connected parties, not filing a profit and loss statement, so do not confuse this with a tax computation.
Consider Yassine, a software consultant in Casablanca, Morocco, who forms a Wyoming LLC to invoice clients in the United States and Europe. In his first year he wires $4,000 of his own savings into the LLC to cover the registered agent fee, software, and a small ad budget. He never makes a sale to a related party. He still has a reportable transaction, the $4,000 capital contribution from himself as the foreign owner, so he must file Form 5472 even though the LLC has no related-party revenue at all.
Non-residents file Form 5472 by attaching it to a pro forma Form 1120 and sending the pair to the IRS by fax or mail, because a foreign-owned disregarded LLC cannot e-file this combination. "Pro forma" means you fill in only the identifying details at the top of Form 1120, write "Foreign-owned U.S. DE" across the top, and leave the income and deduction lines blank. The Form 1120 here is just a cover sheet that carries the 5472.
The IRS sets a fax number and a mailing address specifically for these foreign-owned disregarded entity filings, and the instructions to Form 5472 list the current ones. The deadline matches the corporate calendar: the 15th day of the fourth month after the end of your tax year, which is April 15 for a calendar-year LLC. You can request more time with Form 7004, which generally pushes the deadline by six months.
Here is the sequence most non-resident owners follow:
One detail trips people up. The LLC needs an Employer Identification Number to file, because both the pro forma 1120 and the 5472 ask for the entity's EIN. Without that number, the IRS cannot match your filing to your entity. That is why the EIN comes first in any realistic plan.
You get an EIN without a Social Security Number by filing IRS Form SS-4 and leaving the responsible party's SSN or ITIN field blank, then submitting it to the IRS by fax or mail rather than the online tool. The IRS online EIN application requires a US taxpayer ID for the responsible party, so non-residents are turned away from it and must use the paper SS-4 route instead. The EIN itself is free from the IRS, and by fax the number typically takes a few weeks to come back, though the IRS controls the actual timing and no one can promise a date.
This is the practical bottleneck for most overseas founders. You need the entity formed, then the EIN, and only then can you file Form 5472. Getting all three lined up correctly is exactly the gap a non-resident formation service closes.
CORPBOLT is a U.S. business formation service for non-resident founders that sets up a US (Wyoming) LLC entirely remotely, with no SSN required. Plans start from $349/year, with the EIN included from $599. (corpbolt.com)
To be clear about scope: CORPBOLT can form your Wyoming LLC, obtain the EIN without an SSN, act as your registered agent, and give you a US business and mailing address, all without a US visit. It can also help you get bank-ready so you are prepared to approach a bank or payment platform, though the bank or platform always decides on the account itself. CORPBOLT does not prepare or file Form 5472 for you. For the actual tax filing, work with a US tax professional who handles foreign-owned LLCs, and use the IRS instructions as your source of truth.
Filing Form 5472 late, incompletely, or not at all carries a penalty that begins at $25,000 per form per year under the IRS rules. The penalty applies even when the LLC owes no income tax, because Form 5472 is an information return and the fine is tied to the reporting failure rather than to any tax due. If the IRS sends a notice and the failure continues, additional amounts can accrue.
The penalty is steep precisely because the form is the IRS's window into cross-border related-party activity. Two habits keep founders safe. First, treat the filing as annual and unconditional once you have a foreign-owned disregarded LLC with any related-party transaction. Second, keep contemporaneous records, in English and in US dollars, of every contribution, draw, loan, and inter-company payment, so the numbers on the form can be backed up if questioned.
If you discover you missed a prior year, the practical move is to file the late form rather than leave the gap open. The IRS has procedures for late information returns, and in some cases reasonable-cause relief from the penalty is available, but that is a conversation to have with a US tax professional who can document why the filing was late. Quietly hoping the IRS will not notice a foreign-owned LLC is the riskier path, because the EIN ties the entity to your filing record.
Yes, a foreign-owned single-member LLC with no income usually still files Form 5472, because the obligation is triggered by reportable transactions with related parties, not by profit. The owner's initial capital contribution is itself a reportable transaction, so even a dormant-looking first year typically requires the form. Returning to the Casablanca example, Yassine's LLC made no sales, yet his $4,000 funding alone created the filing duty.
The mental shift that helps is this: Form 5472 is not a tax bill, it is a disclosure of relationships. As long as money or value moved between you and your US entity, the IRS wants the picture, regardless of whether the LLC turned a profit.
No. Form 5472 is an information return that reports related-party transactions, and for a disregarded LLC it attaches to a pro forma Form 1120 that carries no income figures. Any actual US income tax you may owe is handled separately, and you should confirm your personal situation with a US tax professional.
Yes. Both the pro forma Form 1120 and Form 5472 require the LLC's Employer Identification Number, so you must obtain the EIN first. Non-residents get one by filing Form SS-4 with the responsible party's SSN field left blank and submitting it to the IRS by fax or mail.
