Who has to file Form 5472?
#You must file Form 5472 if all three are true:
- You own a single-member US LLC (Wyoming, Delaware, New Mexico, Florida, or any state).
- You are NOT a US person — meaning you are not a US citizen, green card holder, or US tax resident.
- Your LLC had at least one reportable transaction during the year (capital contributions in, distributions out, payments to or from the owner, loans, or any related-party transaction).
Even if your LLC had zero revenue, you still have to file. Capital contributions and distributions count as reportable transactions — and almost every foreign-owned LLC has at least one. The seed money you wired in to open the bank account counts. A reimbursement you took out for a business expense counts. A payment from the LLC to a company you also own counts.
In practice, every active foreign-owned single-member LLC files Form 5472 every year. The only realistic exception is an LLC that has been totally dormant — no bank account, no money in or out, no contracts signed.
What forms do you actually file?
#You file Form 5472 by attaching it to a pro forma Form 1120 (US Corporation Income Tax Return) as the cover. The 1120 is "pro forma," meaning you don't fill in most of it. You only complete the entity identification section and stamp "Foreign-Owned U.S. DE" across the top of page 1.
The full package is:
- Cover letter identifying the filing.
- Pro forma Form 1120 with the "Foreign-Owned U.S. DE" stamp.
- Form 5472 with Parts I, II and III completed, Part IV and Part V as the year's transactions require, and the Part VII questions answered.
- Part V supporting statement that lists each reportable transaction in detail.
- Reasonable Cause Statement (only if you are filing late under DIIRSP).
Missing any one of these can trigger the $25,000 penalty, even if you've technically "filed". The IRS treats incomplete returns the same as missing returns under IRC § 6038A.
How do you file Form 5472 step by step?
#Before you start
- What you need
- LLC legal name and EIN, Owner passport details, Year-end financials, Part V supporting statement, Signed pro forma 1120
- Gather your LLC info: legal name as registered with the state, EIN, US address, date of formation, country of incorporation (US), state of incorporation, NAICS / principal business activity code.
- Gather your owner info: full legal name as on passport, foreign tax ID (FTIN) or self-assigned Reference ID, residential address abroad, country of citizenship, country of tax residence, country of organization of any related foreign entities.
- Add up year-end financials: capital contributions in, distributions out, total assets at year-end (in USD), and a list of every transaction between the LLC and any related party.
- Fill in Form 1120: name, address, item B (EIN) and applicable item E boxes, as the special DE instructions require. Leave income and tax sections blank. Stamp or type "Foreign-Owned U.S. DE" across the top margin.
- Fill in Form 5472: Part I (the LLC, with line 3 checked as a foreign-owned U.S. DE), Part II (25% foreign shareholder), Part III (related party), Part IV (monetary transactions), Part V (contributions, distributions and other DE transactions), Part VII (additional-information questions every filer answers).
- Build the Part V supporting statement: one line per reportable transaction with date, amount, related party, and nature.
- Have the authorized person sign the completed pro forma 1120 in ink, then scan that signed page for fax, as a conservative workflow. Form 5472 has no signature block; electronic-signature rules depend on the document and route.
- Fax the complete package to +1-855-887-7737 (IRS Ogden PIN Unit). Keep the fax confirmation receipt — it is your transmission evidence.
What goes on each part of Form 5472?
#Form 5472 is split by role and transaction type. Part I identifies the LLC, and its line 3 marks a foreign-owned U.S. DE. Parts II and III identify the foreign owner and related party, Parts IV and V report payments, contributions and distributions, and Part VII asks additional yes-or-no questions.
Part II — 25% Foreign Shareholder (lines 4a to 4e): you, the foreign owner. Name and address, US identifying number if any or a reference ID, FTIN, countries where business is conducted, country of citizenship, and countries where you file as a tax resident.
Part III — Related Party (lines 8a to 8g): same as Part II for a single-owner LLC, since you are both the 25%+ shareholder and the related party. For multi-related-party scenarios, you list each one.
Part IV — Monetary Transactions Between Reporting Corporation and Foreign Related Party: dollar amounts of sales, services, rents, royalties, interest, loans, and other payments in each direction.
Part V — Reportable Transactions of a Reporting Corporation That Is a Foreign-Owned U.S. DE: this is where capital contributions, distributions, and most owner-to-LLC payments get reported. Must be backed by a supporting statement.
Part VII — Additional Information: yes-or-no questions every filer answers, starting with whether the LLC imports goods from a foreign related party (line 37). A foreign-owned U.S. DE does not complete lines 43a and 43b. Foreign-owned DE status itself is the Part I, line 3 checkbox.
Can Form 5472 be filed online or e-filed?
#No, not for a foreign-owned US disregarded entity. The IRS Instructions for Form 5472 (Rev. December 2024) state that a foreign-owned U.S. DE cannot file Form 5472 electronically. It files Form 5472 and the pro forma Form 1120 by fax to the IRS at +1-855-887-7737 or by mail to the dedicated Ogden address.
The e-file rule is different for other reporting corporations: the instructions tell a corporation that files its income tax return electronically to see that return's instructions for general information about electronic filing. The ban applies to the foreign-owned DE route, which is the single-member LLC case this page covers.
"Filing online" for a foreign-owned LLC therefore means preparing the package online and sending it by fax. Consumer e-file software is not a route for this package. Fax gives you a timestamped transmission receipt to keep with the exact package; certified mail with a return receipt also works but takes longer. See where to file Form 5472 for the fax number and mailing address.
What does a real Form 5472 filing look like?
#Mei is a Hong Kong resident who incorporated a Wyoming single-member LLC in 2023 to run a Shopify dropshipping business. The LLC had $84,000 in revenue in 2024, $0 in US-source income (all customers were European), and she paid herself $30,000 in distributions to her HK bank account.
Her filing for tax year 2024:
- Pro forma Form 1120: stamped "Foreign-Owned U.S. DE". Entity info filled in. No income or tax fields completed.
- Form 5472 Part IV: blank, because she had no sales, loans, fees or other Part IV transactions with the LLC.
- Form 5472 Part V: box checked for the $5,000 capital contribution she wired in at the start of the year to fund inventory and the $30,000 distribution she took.
- Part V supporting statement: lists both transactions with dates and amounts.
- Faxed to +1-855-887-7737 by April 15, 2025.
Her total US federal tax owed: $0 (all income was foreign-source from a foreign-owned disregarded entity). Her filing obligation: still mandatory.
What are the most common Form 5472 mistakes?
#- Filing only Form 5472 without the pro forma 1120 — the IRS will reject this and treat it as not filed.
- Forgetting to stamp "Foreign-Owned U.S. DE" on the 1120.
- Leaving Part V blank when capital contributions or distributions occurred.
- Assuming a digital-only signature is authorized merely because faxing is allowed. Ink signing of the completed pro forma cover followed by scanning is a conservative workflow, not an absolute IRS ban on every other method.
- Filing for the wrong tax year (the package is for the tax year that ended, not the current year).
- Missing the Part V supporting statement — Part V references it but many DIY filers forget to attach the list.
- Reporting amounts in a foreign currency — all dollar figures must be in USD using the appropriate exchange rate.
- Sending to the wrong fax number — only +1-855-887-7737 is the IRS Ogden PIN Unit fax for these filings.
How much does it cost to file?
#Three ways to do it:
- DIY with IRS forms: $0 in fees, but the IRS estimates 6 hr 34 min per Form 5472 (3 hr 4 min learning about the form plus 3 hr 30 min preparing and sending it, before recordkeeping), and any mistake risks the $25,000 penalty. You also need a fax service ($2-$5).
- Hire a US CPA: $400-$800 typical. Most CPAs are unfamiliar with Form 5472 for foreign-owned disregarded entities, so expect them to either decline the work or take 1-3 weeks while they research it.
- Use Form5472 Prep: $149 Standard (ready in 5-7 business days) or $199 Express (within 3 business days) — same filing either way. IRS fax delivery included. +$99 per additional past year.
Every package we prepare is reviewed by an accountant on our team before we fax it to the IRS. 100% money-back guarantee if we fail to submit.
What happens after you file Form 5472?
#After you file Form 5472, the current instructions do not describe a routine acceptance acknowledgment for the faxed package. Keep the exact submitted package, destination, timestamp, page count, provider receipt and any IRS correspondence together because silence establishes neither delivery nor acceptance.
Do not send a duplicate solely because you have heard nothing. If a notice arrives, follow its instructions and response deadline; a transmission record does not guarantee a penalty will be removed. See receipt confirmation and next steps.

Frequently asked questions
- What's the deadline to file Form 5472?
April 15 of the year following the tax year (e.g. April 15, 2026 for tax year 2025). You get an automatic 6-month extension to October 15 if you file Form 7004 by April 15. The extension shifts the Form 5472 deadline too, since 5472 is attached to the 1120.
- What happens if I file late?
The IRS automatically assesses a $25,000 penalty per form, per year. If they send a notice and you still don't file within 90 days, another $25,000 is added every 30 days. You can request abatement under DIIRSP by attaching a Reasonable Cause Statement explaining why you missed the deadline.
- Can a US CPA file Form 5472 for me?
Technically yes, but most US-based CPAs see this filing once or twice in their career and aren't comfortable with it. Expect $400-$800 and 1-2 weeks of back-and-forth while they research the requirements. Our service starts at $149, takes 15 minutes, and is accountant-reviewed.
- Do I need a US ITIN to file?
No. Form 5472 accepts either a US ITIN or a foreign tax ID (FTIN). If you don't have a FTIN either (some jurisdictions don't issue them), you can use a self-assigned Reference ID. Our wizard auto-generates one for you if you leave the field blank.
- What if my LLC had no transactions at all?
A truly inactive LLC — no bank account, no money in or out — may not have a reportable transaction. But the bar is low: a single capital contribution to open the bank account counts. If you're unsure, file anyway. A $149 filing is cheaper than even a small percentage risk of the $25,000 penalty.
- Do I file Form 5472 or Form 1120 — or both?
Both, together, as one package. The pro forma 1120 acts as the cover document; Form 5472 is the attachment. Neither one alone is a valid filing for a foreign-owned single-member LLC.
- I own multiple LLCs. Do I file once for all of them?
No. Each LLC files its own separate Form 5472 + pro forma 1120. If you own three foreign-owned LLCs, you'll prepare three separate packages and fax three separate filings to the IRS.
- What about state tax filings?
Form 5472 is a federal filing only. State requirements vary: Wyoming has no state income tax and no annual income filing. Delaware charges a $400 franchise tax due June 1 (handled directly via Delaware's website). Florida and Nevada have similar simple franchise/license fees. We handle the federal Form 5472 + 1120; state filings are separate.
- Is IRS fax delivery included in the price?
Yes. IRS fax delivery to +1-855-887-7737 is included with every filing. There is no separate fax fee. You will receive the timestamped fax transmission receipt as transmission evidence.
- Does someone actually review my filing before it goes to the IRS?
Yes. Every package is reviewed by an accountant on our team before we fax it. Nothing goes to the IRS on autopilot. If anything looks off, we'll reach out before submitting.

Under IRC §6038A(d), the Form 5472 penalty is $25,000 for each required Form 5472 not filed on time or filed substantially incomplete, plus $25,000 per 30-day period if the failure continues 90 days after an IRS notice.
