If you own a US LLC from outside the United States, Form 5472 is probably the most important filing on your calendar, and the one most often missed. Since 2017, a foreign owned LLC with one member that the IRS treats as a “disregarded entity” has to file Form 5472 every year, and missing it carries a $25,000 penalty that keeps growing. This guide explains who has to file, what counts as a reportable transaction, the exact address it goes to, and how to put things right if you have already missed a year.
If you are still setting up, our US LLC guide covers formation before you reach this stage.

What Is Form 5472?
Form 5472 is the IRS “Information Return of a 25% Foreign-Owned US Corporation or a Foreign Corporation Engaged in a US Trade or Business.” In plain words, it reports transactions between your US entity and its foreign owner or other related parties. It does not work out any tax by itself. It is a disclosure form. The official overview is on the IRS Form 5472 page.
The difference between an information return and a tax return matters more than it sounds. A tax return says how much you owe. An information return says what happened. You can owe nothing at all in US tax and still face a five figure penalty for not describing that nothing correctly, which is exactly the trap most first year founders fall into. If that has already happened to you and a year or more went unfiled, we have written separately on what happens when Form 5472 was never filed, and how to catch up.
Why a Single Member LLC Suddenly Has to File
This is the part that surprises people. An LLC with one member is normally a “disregarded entity” that the IRS ignores for income tax. But under regulations in force since 2017, a foreign owned single member LLC is treated as a corporation for the limited purpose of Form 5472 reporting. The point was transparency. The US wanted to see money moving between foreign owners and their US entities. So even if your LLC owes no US income tax, you may still have to file this information return.
Who Must File
You generally must file Form 5472 if all three of these are true.
- Your US LLC is owned, directly or indirectly, by a person or company outside the US.
- It is a single member disregarded entity, or a corporation that is at least 25% foreign owned.
- It had at least one “reportable transaction” during the year.
For most foreign owned LLCs the third point takes care of itself, because funding the company is a reportable transaction (see below).
Multi Member LLCs File Something Different
Form 5472 is for disregarded entities and foreign owned corporations. If your LLC has two or more members, it is a partnership by default and it goes down a different road entirely, which is Form 1065 with a Schedule K-1 issued to each member. Foreign partners can also bring withholding obligations under Forms 8804 and 8805.
This catches founders who add a partner part way through the year. Adding a second member changes the federal filing from a pro forma 1120 plus 5472 to a partnership return, and the partnership deadline is March 15, a month earlier than the one you had written down. If you are planning to bring someone in, decide before the year ends and tell whoever does your filing.
What Counts as a “Reportable Transaction”?
Reportable transactions are broad. They cover money and value moving between you and the LLC, including these.
- Capital you put into the LLC, such as funding the bank account.
- Distributions the LLC pays back to you.
- Loans between you and the LLC.
- Payments for services, rent, royalties or the sale of property between related parties.
Forming and funding your LLC usually creates a reportable transaction in year one on its own, which is why almost every foreign owned LLC ends up filing Form 5472, including those that made little or no profit. The mistake many first year founders make is assuming “no revenue” means “no filing.” The very first wire you send from your personal account to the new company account is a reportable contribution, so the requirement is triggered before you have earned a single dollar.
A useful test. If money or value moved between you (or anyone related to you) and the company, it is probably reportable. Money moving between the company and an unrelated customer or supplier is ordinary business activity and is not what this form is about.
| Movement | Reportable on 5472? |
|---|---|
| You wire $2,000 in to open the business bank account | Yes, a capital contribution |
| You take $500 out for yourself | Yes, a distribution |
| You lend the company money and it repays you | Yes, in both directions |
| The company pays you for services you performed | Yes, a related party payment |
| A customer in Germany pays the company $5,000 | No, an unrelated third party |
| The company pays Amazon its seller fees | No, an unrelated third party |
| You pay the state filing fee from your personal card | Yes, in substance. You funded a company expense |
That last row is the one people miss. Paying company costs from a personal card is a contribution in substance even though no wire ever hit the business account. It is also the reason a clean split between personal and business money makes this filing so much easier.
The Nine Parts of Form 5472, and Which Ones Apply to You
The form looks intimidating because it was designed for large multinationals. A single member LLC owned by one person abroad touches very little of it.
| Part | Covers | Typical nonresident LLC |
|---|---|---|
| I | The reporting corporation, meaning your LLC | Complete |
| II | The 25% foreign shareholder, meaning you | Complete |
| III | Related party details | Complete |
| IV | Monetary transactions with foreign related parties | Often left blank by a disregarded entity. Part V is the relevant one |
| V | Transactions of foreign owned US disregarded entities | This is your part. Describe the contributions and distributions |
| VI | Nonmonetary transactions and transactions for less than full consideration | Only if you transferred property rather than cash |
| VII | Additional information (Section 267A, FDII, Section 385) | Rarely applies |
| VIII | Cost sharing arrangements | Does not apply |
| IX | Base erosion payments (Section 59A) | Does not apply |
For a typical one owner LLC that took in some capital and paid out a distribution, the real work is Parts I, II, III and V. That is a couple of pages of identification plus two dollar figures.
The Pro Forma 1120, What to Fill In and What to Leave Blank
Form 5472 cannot be filed on its own. A disregarded entity attaches it to a pro forma Form 1120, which acts purely as a cover sheet. “Pro forma” here means you are not reporting income on it. You are using the form as an envelope.
On that 1120 the instructions ask only for the name and address of the LLC and items B and E on the first page. Item B is the EIN, and item E holds the boxes for an initial return, final return, name change or address change. The income statement, deductions, balance sheet and tax computation schedules stay empty. Write “Foreign-owned U.S. DE” across the top of the form, which is the wording the Instructions for Form 5472 use.
Two things follow from this. Filing a pro forma 1120 does not make your LLC a corporation and does not elect corporate taxation. It changes nothing about how you are taxed. And because it is not a real income tax return, it cannot go through the ordinary e file channels along with your personal taxes.
How to fill in Form 5472 for a single member LLC, part by part
This follows the Instructions for Form 5472 (revised December 2024) for the common case. One owner living abroad, money in and money out, nothing else.
| Where | What goes there | The nonresident catch |
|---|---|---|
| Part I, line 1a | The name and address of your LLC | Include the suite or unit number after the street address |
| Part I, lines 1d and 1e | A description of the principal business activity and its code | Use the activity the LLC actually carries on, not your home country business |
| Part I, line 1g | How many Forms 5472 you are filing for the year, including this one | One per related party with reportable transactions, so usually 1 |
| Part I, line 1h | Total US dollar value of related party transactions | For a foreign owned DE this includes the amounts reported in Part V, not only Parts IV and VI |
| Part I, line 1j | Box for the first year the LLC files a Form 5472 | Tick it in year one |
| Part II, lines 4a to 4e | The direct 25% foreign shareholder, meaning you | Line 4b(1) asks for a US identifying number “if any”. If you have no SSN or ITIN, use a reference ID number on line 4b(2) instead (below) |
| Part III | The related party you had transactions with | All filers complete Part III even if it is the same person as in Part II. Line 8b follows the same reference ID rule |
| Part IV | Monetary transactions with a foreign related party | Covers things like amounts lent or borrowed. Contributions and distributions go in Part V unless already entered here |
| Part V | Tick the box and attach a statement | The statement describes amounts paid or received in connection with forming and running the LLC, “including contributions to, and distributions from, the entity” |
The reference ID number, for owners with no SSN or ITIN
Most foreign owners have no US identifying number, and an empty box on a $25,000 form makes people nervous. The instructions cover it. Where no US identifying number is entered, you enter a reference ID number that the LLC assigns to you. The rules are short.
- Letters, numbers or both. No spaces or special characters.
- 50 characters at most.
- Use the same reference ID for the same person every year.
Something like OWNER001 works. Write it down with your tax records, because the form next year has to match.
How and When to File
- Attach Form 5472 to a “pro forma” Form 1120 as described above.
- You must have an EIN. The form cannot be filed without one. See our guide to getting an EIN without an SSN if you do not have one yet.
- Deadline. Generally April 15 for the prior calendar year, with an extension to October 15 available by filing Form 7004 on time. Every date is in our US tax filing deadline guide.
- Where. Foreign owned disregarded entities use a dedicated destination, not the normal 1120 address.
| Channel | Destination |
|---|---|
| Fax | 855 887 7737. Send at 300 DPI or higher, or it may be unreadable and treated as not filed |
| Internal Revenue Service, 1973 Rulon White Blvd, M/S 6112, Attn PIN Unit, Ogden, UT 84201 |
Confirm both against the current Instructions for Form 5472 before you send. IRS destinations change, and a correctly completed form sent to the wrong place is still a late filing. Keep the fax confirmation or the postal receipt. With a form carrying this penalty, evidence of the send date is worth more than the filing itself.
Filing an Extension with Form 7004
If April is going to slip, Form 7004 buys you six months, to October 15 for a calendar year filer. Two conditions. It must be filed by the original due date, and the Form 5472 instructions say a foreign owned DE must fax or mail it, with the code for Form 1120 entered on Form 7004, Part I, line 1. The Form 7004 instructions themselves list no fax number and no separate row for foreign owned DEs, so confirm the destination against both sets of instructions before you send, and keep the confirmation.
An extension of time to file is not an extension of time to pay anything you might owe elsewhere, but for a pro forma filing with no tax on it, the extension really is just breathing room. If you are unsure whether you will make April, file the 7004. It costs nothing and removes the risk.

The $25,000 Penalty for Getting It Wrong
The penalty for failing to file Form 5472, or filing it late or incomplete, is $25,000 per form. It does not stop there. If the failure continues more than 90 days after the IRS notifies you, an additional $25,000 applies for each 30 day period the failure persists. There is no small company exemption and no first year grace period.
Read that escalation clause carefully, because it changes what you should do with an IRS letter. The single worst response to a notice about a missing 5472 is to set it aside and think about it. Ninety days after the notice the meter starts running in $25,000 steps.
The Record Keeping Requirement Nobody Mentions
The same $25,000 penalty applies to failure to keep the records the regulations require. It is a separate obligation from filing the form. You must be able to back up the related party transactions you reported.
In practice this is not a burden for a small LLC. Keep bank statements for every year, a simple ledger of transfers between you and the company, and copies of each filed 5472 and pro forma 1120. A folder per tax year with those three things in it satisfies the requirement and takes minutes a month.
Common Myths
- “My LLC made no money, so I do not file.” Wrong. Form 5472 is about reportable transactions, not profit. Funding the LLC counts.
- “It is a disregarded entity, so there is nothing to do.” Wrong. Disregarded for income tax, but specifically required to file 5472.
- “I can e file it with my personal taxes.” Not through the usual route. The pro forma 1120 plus 5472 is filed separately by fax or mail.
- “My LLC never had a bank account, so there were no transactions.” Rarely true. If you paid the state fee or the registered agent from your own card, you funded the company.
- “Filing an 1120 means I will be taxed as a corporation.” No. A pro forma 1120 is an envelope for the 5472 and changes nothing about your tax treatment.
- “My registered agent handles this.” Almost never. Registered agent service covers service of process and state mail, not federal information returns. Check what you actually bought.
A Simple Year One Example
Say you form a Wyoming LLC in March, wire in $2,000 to open the bank account, pay the $102 state filing fee from your personal card, and later take a $500 distribution for yourself. You earned modest revenue from foreign clients and have no US office. For income tax, your disregarded LLC may owe nothing. For reporting, your year looks like this.
| Date | Movement | Amount | Reportable |
|---|---|---|---|
| March | State filing fee paid from personal card | $102 | Yes, a contribution |
| April | Wire from personal account to open business account | $2,000 | Yes, a contribution |
| June to November | Client payments received from customers abroad | $8,400 | No, unrelated parties |
| September | Distribution to yourself | $500 | Yes, a distribution |
| Reported in Part V | $2,102 in, $500 out | ||
Two numbers on one part of one form, attached to a nearly empty 1120, faxed by April 15. Profit was irrelevant. The transfers triggered the filing. That is the entire obligation, and it is why the $25,000 penalty stings so much when it lands. The work avoided was about twenty minutes.
What If You Already Missed a Year?
If you discover you should have filed Form 5472 for a past year, do not ignore it. The penalty grows and the IRS can assess it automatically. The usual path is to file the late return as soon as possible and, where it fits, attach a reasonable cause statement explaining why it was missed.
A reasonable cause statement is a short written explanation of why the failure happened despite ordinary business care. It is not an apology and not a plea. What tends to help is specifics. What you understood at the time, what changed, when you discovered the error, and what you have put in place so it does not happen again. What tends not to help is “I did not know,” standing alone. Because abatement depends on the facts and the amounts are large, this is the moment to bring in an international tax professional rather than improvising.
Filing voluntarily before the IRS contacts you is materially better than waiting. Once a notice arrives you are inside the 90 day window that starts the escalating penalty, and your position is a lot weaker.
Other Filings That Often Travel With It
Form 5472 rarely sits alone. Depending on your situation you may also meet these.
- Form 1040-NR, your own personal US return, if you have income effectively connected to a US trade or business.
- The annual obligation in your state, which is separate from anything federal. Wyoming, for example, requires an annual report with a $60 minimum fee, and missing it eventually dissolves the company.
- Form 7004, the extension described above.
- BE-13 or related BEA surveys, a Bureau of Economic Analysis requirement that can apply to new foreign owned US entities. It is not an IRS form and hardly anyone has heard of it, which is exactly why it is worth asking about.
- Reporting in your home country. Many countries require disclosure of a foreign company you control. The FEMA and ODI rules in India are a common example. Check both sides of the border, because only one of them is covered by any US filing.
Our US tax filing service covers the federal side of this for nonresident owners if you would rather not put it together yourself.
How to Stay Compliant
- Keep a simple ledger of every transfer between you and the LLC throughout the year.
- Never pay company costs from a personal card once the business account exists. It keeps your Part V figures clean.
- Get your EIN early so you are ready to file.
- Write April 15 in your diary, and file Form 7004 the moment it looks tight. Our compliance calendar builds every federal and state date for your LLC and exports them to your phone.
- Keep the proof of filing alongside the return itself.
- Use an international accountant if your transactions go beyond simple contributions and distributions.
| When | What |
|---|---|
| Throughout the year | Log every transfer between you and the company |
| January | Total the contributions and distributions for the year |
| By April 15 | File 5472 plus the pro forma 1120, or file Form 7004 |
| By October 15 | Final deadline if you extended |
| State deadline | Annual report, separately. Check the date for your state |
Frequently Asked Questions
Does Form 5472 mean I owe US tax?
Not by itself. Form 5472 is an information return. Whether you owe income tax is a separate question that depends on effectively connected income and tax treaties.
My LLC was dormant. Do I still file?
If any reportable transaction occurred, including the capital you put in to open the bank account, you file. A year with truly zero transactions is rare.
Can my accountant file it for me?
Yes, and for anything beyond simple contributions and distributions, an accountant who works across borders is strongly recommended.
Is Form 5472 the only thing I file?
It is the core federal information return for a foreign owned single member LLC, but your home country may have its own reporting on the foreign company too. Check both sides.
Can I e file the 5472?
Not as part of a normal personal e file. The pro forma 1120 plus 5472 goes by fax or mail to the dedicated destination.
What if my LLC has two members?
Then 5472 is generally not your form. A multi member LLC files Form 1065 with a Schedule K-1 for each member, due March 15.
Do I file one 5472 per owner?
One form per related party with reportable transactions. A single owner with a single set of transactions files one.
Is the $25,000 penalty ever waived?
It can be abated for reasonable cause, but that depends on the facts and is never guaranteed. Filing late and voluntarily is far better than being found.
Does filing a pro forma 1120 make me a corporation?
No. It is a cover sheet for the 5472 and does not change your tax classification.
What if I formed the LLC in December and did nothing?
If you funded it at all, including paying the state fee yourself, you likely have a reportable transaction for that short first year.
