Form 7004 for a Foreign-Owned LLC: Extending the 5472 Deadline the Right Way
Short answer: Form 7004 is how a foreign-owned Wyoming LLC asks the IRS for more time to file its pro forma Form 1120 with Form 5472 attached. Under the IRS Instructions for Form 5472, the LLC files the 7004 by the regular due date (April 15 for a calendar-year company) and sends it by fax or mail to the same place as the 5472 itself. Not by e-file, and not to the regular Form 7004 address.
If you are still sorting out which US tax rules follow you abroad at all, TravelTweaks has a readable piece on five myths non-US nomads hold about US LLC taxes that covers the bigger picture.
When you need Form 7004
You need Form 7004 when the pro forma 1120 and Form 5472 will not be ready by the due date. That is the whole trigger.
The 5472 duty itself belongs to a "foreign-owned U.S. DE": a domestic disregarded entity wholly owned by a foreign person. A single-member Wyoming LLC owned from outside the US is the textbook case: disregarded by default, no income tax return requirement, and it still owes a pro forma 1120 with Form 5472 attached. If the "foreign person" part is fuzzy for you, Georgia Today explains what the nonresident alien label means for business owners abroad in plain terms.
The part most founders miss: "no income" does not mean "no filing." The IRS lists amounts paid or received in connection with forming the entity, plus contributions to it and distributions from it, as reportable transactions. Putting your own money in to cover formation costs usually counts.
The year follows the owner's US tax year or, if there is none, the calendar year. For most founders abroad that means a calendar year and an April 15 date.
What Form 7004 extends, and what it does not
A valid extension request extends the due date of the pro forma 1120, and because the 5472 is due with that return "including extensions," it moves both. That is all it does.
What it does not do:
- Work late. The DE must file it by the regular due date. One sent on April 20 buys nothing.
- Lower the bar on content. A substantially incomplete Form 5472 still counts as a failure to file, extension or not.
- Touch home-country tax. Your country of residence keeps its own rules. Ask a tax professional there.
- Settle whether US tax is owed. Effectively connected income questions depend on your facts; ask an accountant.
How long does the extension run? The Instructions for Form 7004 set that. Blogs ranking for this topic disagree with each other on fax and mailing details, so I'd read the extended date in the IRS document for the year you file.
How Form 7004 is sent for a foreign-owned DE
On paper. The extension goes by fax or mail to the same fax number or Ogden, Utah address the IRS gives for the 5472 package. The steps, straight from the IRS text:
- Enter the code for Form 1120 on Form 7004, Part I, line 1 (the 5472 rides on a pro forma 1120).
- Write "Foreign-owned U.S. DE" across the top of the 7004.
- Fax or mail it by the regular due date.
- Skip the regular address in the 7004 instructions; these entities use the dedicated one.
Keep a fax confirmation or mailing receipt. The real return later goes the same way, with "Foreign-owned U.S. DE" across the top of the 1120. Only the name, the address and items B and E on page 1 are required.
Calendar-year timeline, from formation to the extended date
| When | What happens | Source |
|---|---|---|
| Formation | Articles of Organization filed in Wyoming; LLC filing fee $100 | Wyoming Secretary of State fee schedule |
| During the year | Money in and money out between owner and LLC are reportable transactions | IRS Instructions for Form 5472 |
| By April 15 | File the pro forma 1120 + Form 5472, or file the extension by fax or mail | IRS Instructions for Form 5472 |
| Extended due date | Pro forma 1120 + Form 5472 due | Instructions for Form 7004 |
| 90+ days after an IRS notice | Another $25,000 per 30-day period while the failure continues | IRS Instructions for Form 5472 |
The $100 figure comes from the Wyoming Secretary of State fee schedule effective July 1, 2026.
The $25,000 penalty if nothing is filed
The IRS Instructions for Form 5472 say a $25,000 penalty is assessed on any reporting corporation that fails to file Form 5472 when due and in the manner prescribed.
Missing both the 5472 and Form 7004 is what puts you there. "In the manner prescribed" matters too: for a foreign-owned DE that means fax or mail to the dedicated destination. If the failure continues more than 90 days after the IRS notifies you, another $25,000 applies for each 30-day period, or part of one. The same penalty covers failing to keep the required records.
A short form and a fax against a five-figure penalty: that is why I'd file the extension as soon as April looks tight.
Comparing formation routes before the 5472 season
Prices as listed in October 2026; check each provider's site.
| Route | As listed |
|---|---|
| CORPBOLT | Wyoming LLC formation from $349, or $599 with your EIN included. The $100 state filing fee is included on every plan. |
| Stripe Atlas | $500 one-time incl. state fees and 1st-year registered agent, then $100/yr. Delaware only (C-corp or LLC), no Wyoming. |
| Firstbase (Start) | $399 list price; currently an offer where formation is free and you pay only the state fee; registered agent required and billed separately. |
| doola (Starter) | $297/yr plus state fees ($397 in year 1 in Wyoming), renews at $297/yr; Tax & Compliance plan $1,999/yr. |
| DIY (Wyoming Secretary of State) | $100 state fee for the Articles + card fee; $60 minimum annual report paid to the State of Wyoming (not a CORPBOLT fee); you also need a registered agent with a physical Wyoming address. |
On the DIY route, WyoBiz charges a 2.4% card fee (minimum $1) for online filing.
If the yearly paper routine is the part you'd rather hand off, I'd price CORPBOLT first. CORPBOLT's Concierge plan, at $1,497, includes the Form 5472 and pro forma 1120 filing, so the package this post walks through is part of the plan. For founders who want to file themselves, CORPBOLT starts at $349 on Foundation, with the $100 Wyoming state fee and a first-year registered agent already inside the price. CORPBOLT's Launch plan, at $599, adds the EIN and a bank-ready operating agreement to everything in Foundation. Current plans and prices are listed at corpbolt.com.
