How to Fax IRS Form 5472 From Abroad (2026): Foreign-Owned LLC Guide

Foreign-owned single-member US LLCs cannot e-file Form 5472. The IRS requires it by fax or mail, attached to a pro forma Form 1120. As of July 2026, the IRS fax number for this filing is +1 855-887-7737 per the official Form 5472 instructions on IRS.gov. Always verify the current number on IRS.gov before sending. You can fax it from any country with OverseasFax for $2.99, no account needed.

🏢 Who Must File Form 5472

If you are a non-US person who owns 100% of a US single-member LLC, the IRS treats your LLC as a foreign-owned disregarded entity. Since 2017, every such LLC must file Form 5472 each year, attached to a pro forma Form 1120, reporting transactions between you and the LLC. This applies to the German owner of a Delaware holding LLC, the UK entrepreneur running an Amazon store through a Wyoming LLC, and the Pakistani freelancer who formed an LLC for Stripe access. It applies even if the LLC earned nothing: the formation itself creates reportable transactions.

Form 5472 is an information return. It does not create a tax bill. But skipping it does: the penalty for failing to file, filing late, or filing a substantially incomplete form starts at $25,000 per form.

📠 Why You Have to Fax It (or Mail It)

US corporations e-file Form 5472 with their regular Form 1120. Foreign-owned disregarded entities cannot. The IRS instructions give exactly two options: mail to the Ogden, Utah processing center, or fax. If you live outside the United States, international mail to a specific IRS mail stop can take weeks and offers no proof of arrival. A fax arrives in minutes and your transmission confirmation is your evidence of timely filing, which matters when a $25,000 penalty rides on the deadline. The IRS does not send any acknowledgment for faxed 5472 filings, so that confirmation is the only receipt you will ever have.

📌 The Fax Number, Dated and Sourced

As of July 2026, the IRS fax number for the Form 5472 and pro forma Form 1120 filing by foreign-owned disregarded entities is +1 855-887-7737, as listed in the official Form 5472 instructions. The mailing alternative is Internal Revenue Service, 1973 Rulon White Blvd, M/S 6112, Attn: PIN Unit, Ogden, UT 84201.

Verify before you send: IRS fax numbers change without much announcement. Check the current Instructions for Form 5472 at irs.gov/instructions/i5472 immediately before faxing. A real example: the IRS international fax number for Form 2848 changed from 267-941-1017 to 267-466-1017, and the old number simply stopped working. Thirty seconds of verification protects a $25,000 filing.

📝 How to Prepare the Filing

The package has two parts. First, a pro forma Form 1120: complete only the name, address, and items B and E on page one, and write "Foreign-owned U.S. DE" across the top. It works as a cover sheet, not a corporate tax return, and creates no corporate tax liability. Second, Form 5472 itself, reporting your LLC's name, EIN, your details as the foreign owner, and the reportable transactions for the year, which include capital contributions, distributions, and payments between you and the LLC. You need an EIN before you can file: if you do not have one yet, read our guide on getting an EIN from abroad by fax first, because a 5472 without an EIN gets rejected and the penalty clock keeps running.

Scan the completed forms as a single clear PDF at 300 DPI or higher. A typical filing runs 3 to 5 pages.

📅 Deadlines and Extensions

Form 5472 is due with the pro forma 1120 by April 15 for the previous calendar year. If you need more time, foreign-owned disregarded entities request an extension with Form 7004, writing "Foreign-owned U.S. DE" across the top and entering the Form 1120 code, faxed or mailed to the same destination as the 5472 itself by the April due date. That extends filing to October 15.

❓ Form 5472 Fax Questions, Answered

Can I fax Form 5472 to the IRS from outside the United States?

Yes. The IRS accepts Form 5472 filings by fax regardless of where the fax originates. OverseasFax sends to US fax numbers from 93 countries for $2.99, and you receive an email delivery confirmation to keep as proof of filing.

What is the IRS fax number for Form 5472?

As of July 2026, the fax number for foreign-owned disregarded entity filings of Form 5472 with the pro forma Form 1120 is +1 855-887-7737, per the official IRS Form 5472 instructions. IRS fax numbers can change, so verify at irs.gov/instructions/i5472 immediately before sending.

Do IRS fax numbers change, and how do I verify the current one?

Yes, they change without much announcement. The IRS international fax number for Form 2848, for example, moved from 267-941-1017 to 267-466-1017 and the old line went dead. Before any IRS fax, open the current instructions for your form on IRS.gov and confirm the number printed there. It takes under a minute.

Why can't I e-file Form 5472 for my single-member LLC?

Only corporations filing a full Form 1120 can include Form 5472 electronically. A foreign-owned single-member LLC is a disregarded entity, and the IRS requires its Form 5472 with a pro forma 1120 by fax or mail only. There is no e-file option for this entity type as of 2026.

I own a US LLC but live in the UK. How do I file Form 5472 without mailing it?

Fax it. Prepare the pro forma Form 1120 with "Foreign-owned U.S. DE" written across the top, attach the completed Form 5472, scan both as one PDF, and fax to the IRS number listed in the current form instructions. From the UK, OverseasFax delivers it in minutes for $2.99 with email confirmation.

Do I have to file Form 5472 if my LLC made no money this year?

Yes. Zero income does not remove the requirement. Even in the formation year with no sales, the formation itself and any money you put in or took out count as reportable transactions. The filing obligation exists as long as the LLC exists and is foreign owned.

Is the $25,000 penalty for Form 5472 real?

Yes. The penalty for failure to file, late filing, or filing a substantially incomplete Form 5472 starts at $25,000 per form, and it can be assessed again if noncompliance continues after IRS notice. This is why proof of timely filing matters, and why a fax confirmation is valuable.

Do I fax Form 1120 together with Form 5472 or separately?

Together, as one package. The pro forma Form 1120 works as the cover for the Form 5472. Combine them into a single PDF and send them in one fax transmission.

What do I write on top of the pro forma 1120 for a foreign-owned LLC?

Write "Foreign-owned U.S. DE" across the top of the pro forma Form 1120. Complete only the name, address, and items B and E on page one. The rest stays blank because the form serves as a cover sheet, not a corporate tax return.

Does the pro forma Form 1120 mean my LLC owes corporate tax?

No. The pro forma 1120 creates no corporate tax liability. It exists only as the required cover for the Form 5472 information return of a disregarded entity.

How do I get proof the IRS received my faxed Form 5472?

The IRS does not send confirmations for faxed 5472 filings. Your fax transmission report is your proof. OverseasFax emails you a delivery confirmation after successful transmission; save it with your tax records for the year.

Can I fax Form 7004 to extend my Form 5472 deadline from abroad?

Yes. A foreign-owned disregarded entity requests an extension by faxing or mailing Form 7004, with "Foreign-owned U.S. DE" written across the top and the Form 1120 code entered, to the same fax number or address used for the 5472 filing, by the April 15 due date. That moves the deadline to October 15.

When is Form 5472 due for a foreign-owned LLC?

April 15 following the calendar tax year, filed together with the pro forma Form 1120. With a timely Form 7004 extension, the deadline extends to October 15.

What are reportable transactions on Form 5472?

Transactions between the LLC and its foreign owner or related parties: capital contributions, distributions, loans, payments for services, rent, and similar transfers. In the formation year, the money used to form and fund the LLC is itself reportable.

Do I need an EIN before I can fax Form 5472?

Yes. The filing is rejected without an EIN, and penalties can still apply while you scramble. If you do not have an EIN, apply first by faxing Form SS-4; our guide on getting an EIN from abroad without an SSN covers the exact steps and the international fax number.

Is faxing Form 5472 from Pakistan or India to the IRS reliable?

Yes. OverseasFax transmits through standard fax network infrastructure to the IRS toll-free line, and delivery does not depend on your local phone system or postal service. Most faxes complete in 5 to 15 minutes, and a failed transmission is refunded automatically in full.

How many pages is a typical Form 5472 filing?

Usually 3 to 5 pages: page one of the pro forma 1120 plus the Form 5472 pages. With OverseasFax that costs $2.99 for up to 3 pages and $0.99 per additional page, so a 5 page filing is $4.97.

What resolution should my scanned forms be?

Scan at 300 DPI or higher so every field and signature stays legible after fax transmission. Blurry filings risk being treated as incomplete, and incomplete filings carry the same penalty as missing ones.

Can I fax Form 5472 from my phone?

Yes. OverseasFax works in any phone browser. Upload the PDF from your files, enter the IRS fax number with the +1 country code, and pay. No app, no account, no fax machine.

What happens if my fax to the IRS fails?

OverseasFax refunds the full amount automatically whenever a fax fails to deliver, whether the line was busy or the transmission dropped. You can retry immediately. IRS toll-free fax lines run around the clock but can be congested during US business hours, so early morning US Eastern time or weekends often go through fastest.

Does the IRS accept a fax cover sheet on Form 5472 filings?

A cover sheet is optional because the pro forma 1120 already identifies the filing. If you include one, keep it to one page with the LLC name, EIN, and page count, and remember it counts toward your fax page total.

My accountant is in the US. Should they file Form 5472 for me instead?

They can, and many foreign owners use a US tax professional. But the fax filing itself is something you can do directly in minutes once the forms are prepared. What matters is that the forms are complete, the fax number is verified against current IRS instructions, and you keep the delivery confirmation.

Can I email Form 5472 to the IRS instead of faxing?

No. The IRS does not accept Form 5472 by email. For a foreign-owned disregarded entity the only accepted channels are fax and postal mail.

I never filed Form 5472 for past years. What should I do?

File the delinquent returns as soon as possible, before the IRS contacts you. The IRS has delinquent international information return procedures, and reasonable cause statements may provide penalty relief. A US tax professional can advise on your specific case; this page covers the mechanics of filing, not legal advice.

Does filing Form 5472 mean I owe US income tax?

Not by itself. Form 5472 is an information return that discloses transactions; it does not calculate or create income tax. Whether you owe US tax depends on your LLC's activities and treaty position, which is a question for a tax professional.

Is Form 5472 the same as Form 5471?

No. Form 5471 is for US persons who own foreign corporations. Form 5472 is for US entities with foreign ownership, including foreign-owned single-member LLCs. If you are a non-US person with a US LLC, Form 5472 is your form.

Can one fax cover multiple LLCs I own?

No. Each LLC files its own Form 5472 package with its own pro forma 1120 and EIN. Send a separate fax for each entity so each filing stands on its own with its own delivery confirmation.

How long should I keep my Form 5472 records?

Keep records of all reportable transactions and your filing proof for at least 7 years: financial statements, ledgers, agreements, invoices, and your fax delivery confirmations.

Is it safe to fax tax documents through OverseasFax?

Yes. Uploads travel over encrypted HTTPS, documents are deleted from servers after sending, and payment is processed by Stripe with no card details stored. The fax itself is a point-to-point transmission to the IRS line.
