Form 5472 in Your LLC's First Year (2026)

If you formed a US LLC this year as a non-resident, your first Form 5472 is almost certainly already required before your first customer, before your first invoice, before the business does anything at all. The act of setting the company up moves money between you and the entity, and that money is exactly what Form 5472 exists to report.

Year one is where most non-resident founders get caught. The company feels like a shell. Nothing happened. The Stripe account is still pending. So April 15 passes quietly, and the $25,000 penalty starts running against a business that never earned a dollar.

This guide covers the first year specifically: which start-up transactions are reportable, when your first deadline actually falls if you formed in March versus November, the initial-year checkbox on line 1j, and what your first Part V should look like.

The Short Answer: Year One Almost Always Means a Filing

If you formed a foreign-owned single-member US LLC during the tax year, you should plan on filing. Form 5472 is triggered by reportable transactions with a foreign related party, and for a brand-new LLC the formation itself supplies them. The IRS instructions list amounts paid or received in connection with the formation of the entity, plus contributions to and distributions from it, as reportable in Part V.

The filing is a Form 5472 attached to a pro forma Form 1120 the 1120 is a cover sheet carrying your name, address, EIN and the “Foreign-owned U.S. DE” notation, and the 5472 carries the substance. If any of that is new to you, start with our complete Form 5472 guide for foreign-owned LLCs and come back here for the first-year specifics.

Why Formation Itself Creates a Reportable Transaction

A US LLC cannot form itself. Someone pays the state, and in a single-member foreign-owned LLC that someone is the foreign owner a related partyin the IRS’s vocabulary. The moment your personal card is charged for a filing fee on the entity’s behalf, value has passed between a foreign person and a US disregarded entity, and that is the precise event Form 5472 tracks.

This is why “my LLC is brand new” is the weakest possible argument for skipping the form. A ten-year-old dormant LLC might genuinely have a transaction-free year. A newly formed one essentially never does, because forming it cost money that came from you.

Note that the regulations treat the LLC as a corporation solely for this reporting requirement. It is still disregarded for income tax; it simply is not disregarded for disclosure.

Which First-Year Transactions Are Reportable?

Nearly every line item on a founder’s start-up receipt list is reportable, and a few things founders expect to report are not. The test is not “was this a business expense?” but “did money or value move between the LLC and a foreign related party?”

Note the pattern: the reportable rows all involve you. Revenue and vendor costs sit outside Form 5472 entirely unless the counterparty is related to you. For the full catalogue beyond year one, see Form 5472 reportable transactions explained.

When Is Your First Form 5472 Due?

April 15 of the year after formation, in every case below. A foreign-owned US disregarded entity uses the same tax year as its owner for US filing purposes or, if there is none, the calendar year so your first tax year ends on December 31 no matter which month you formed, and the pro forma 1120 with Form 5472 attached follows the standard corporate due date.

Run your own dates through the deadline calculator if your owner-level tax year is anything other than the calendar year, or if you want the extended date in writing.

Does a Mid-Year LLC Get a Shorter Deadline?

No a short first year does not change your due date. It only shortens the period you are reporting on. An LLC formed on November 20 reports roughly six weeks of transactions, and it reports them on the same schedule as an LLC that operated all twelve months.

The practical consequence surprises people: a December LLC can be legally required to file a full Form 5472 package covering a handful of days of existence. If you paid the state fee and put $100 in a bank account on December 28, that is your first tax year, and the form is due the following April 15. Founders who form in Q4 to “get ready for January” often assume year one starts in January. It does not.

The reverse trap is just as common: forming in late December to capture an earlier start date, then discovering it created an extra filing year that would not have existed had the paperwork been dated in January.

Line 1j: The Initial-Year Checkbox Nobody Tells You About

Part I of Form 5472 has a small checkbox at line 1j that only first-year filers should touch. The IRS instructions describe it plainly: check the box if this is the first year the US reporting corporation has filed a Form 5472. Tick it on your first filing; leave it blank every year after.

It is a one-second box that does real work. It tells the IRS your entity is new rather than delinquent that there is no missing prior-year form behind this one. Leaving it unchecked on a genuine first filing invites exactly the question you do not want.

While you are in Part I, two neighbouring lines matter in year one:

• Line 1f the total US-dollar value of all foreign related party transactions reported in Parts IV and VI, and, because you are a foreign-owned DE, Part V. In a typical first year this is simply your formation costs plus contributions.
• Line 1g the number of Forms 5472 being filed for the tax year, including this one. For a solo founder with one related party, that is 1.

What Goes in Part V in Year One

Part V is where a first-year filing lives. For a foreign-owned disregarded entity it captures amounts paid or received in connection with the formation, dissolution, acquisition and disposition of the entity, including contributions to and distributions from it. Year one is, by definition, the formation year so Part V is rarely empty.

A realistic first-year Part V picture looks like this:

• Formation-related amounts:the state filing fee, the formation service invoice, the first registered agent charge anything you paid on the LLC’s behalf to bring it into existence
• Contributions:every transfer you made into the LLC’s account during the year, from the $100 that opened it to a five-figure working-capital wire
• Distributions: anything you moved back out to yourself before December 31

Do not net these against each other, and do not omit small amounts because they feel trivial. There is no minimum threshold for a reportable transaction. A substantially incomplete Form 5472 carries the same penalty as one that was never filed, so a $50 fee left off Part V is not a rounding difference it is an accuracy problem.

The “We Haven’t Started Trading Yet” Trap

This is the single most expensive first-year assumption: no customers, no revenue, therefore no filing obligation. Form 5472 never asks about customers. It asks what moved between the entity and its foreign owner, and in a start-up year the answer is always “the money that got it off the ground.”

The founders most exposed here are the ones whose plans stalled: the Stripe application that was never approved, the product that never launched, the LLC formed for a client contract that fell through. The company exists, formation was paid for, and the form is due anyway.

If your LLC stays dormant into later years, the analysis changes slightly there is one narrow situation where a transaction-free year genuinely needs no filing. We cover it in Form 5472 with no activity or zero income. It essentially never applies to year one.

What You Need Before You Can File

You cannot file Form 5472 without an EIN. That single dependency causes more first-year lateness than anything else, because non-residents without an SSN or ITIN apply on Form SS-4 by fax or phone, and processing takes far longer than the online route US persons use.

Two things worth knowing early. First, an ITIN is not required to file Form 5472 itself if you have no US tax ID, you use a reference ID number for the foreign owner in Part II. Second, the deadline does not wait for your EIN. Our EIN guide for foreign-owned LLCs walks through the SS-4 route.

If the EIN will not land in time, file Form 7004 by April 15 to move the return to October 15. For a disregarded entity, enter the Form 1120 code on Form 7004 Part I, line 1, because the 5472 is attached to a pro forma 1120. The 7004 goes in by fax or mail like everything else in this package.

First-Year Filing, Step by Step

Step 1: Reconstruct your formation spending

Pull every payment connected to the LLC from the formation date to December 31 personal card charges, bank transfers, formation service receipts. Mark each one as paid by you or by the LLC. Only the first group, plus contributions and distributions, reaches Part V.

Step 2: Confirm your tax year

Formation date to December 31, unless your owner-level US tax year says otherwise. Enter those dates in the header of the pro forma 1120.

Step 3: Prepare the pro forma 1120

Name, address, EIN, tax year, and “Foreign-owned U.S. DE” written across the top. Income and deduction lines stay blank.

Step 4: Complete Form 5472

Part I with the DE checkbox and line 1j ticked, Part II for the foreign owner, Part III for the related party, and Part V for your formation amounts, contributions and distributions.

Step 5: Fax or mail by April 15

Fax to (855) 887-7737 or mail to the IRS at 1973 Rulon White Blvd., M/S 6112, Attn: PIN Unit, Ogden, UT 84201. A foreign-owned DE cannot e-file this package. Keep the fax confirmation it is your proof of timely filing. Our step-by-step filing walkthrough covers the mechanics in detail.

First-Year Mistakes That Cost $25,000

The penalty for a missing or substantially incomplete Form 5472 is $25,000 per form, per year, with a further $25,000 for each 30-day period the failure continues once the IRS has issued a notice and 90 days have passed. It is assessed automatically, and it is not scaled to your revenue. These are the first-year versions:

• Skipping year one entirely because the business never launched
• Filing an empty Part V when formation fees and an opening deposit belonged in it
• Assuming a December LLC has nothing to file for its few days of existence
• Waiting on the EIN past April 15 instead of filing Form 7004
• Attempting to e-file through consumer tax software and assuming it went through
• Leaving line 1j unchecked on a genuine first filing

Missed a first year already? It is fixable, and filing late voluntarily is dramatically better than waiting for a notice see filing Form 5472 late for prior years. The official rules are at irs.gov/instructions/i5472 and the form itself at irs.gov/forms-pubs/about-form-5472.

How Year One Differs From Every Year After

Once the first filing is behind you, the annual routine gets simpler: the same two documents, the same April 15 date, minus the formation amounts and minus the line 1j checkbox. What does not change is the obligation a foreign-owned LLC keeps filing for as long as it has reportable transactions, and dissolution is itself reportable.

Year one is heavier for one reason: it is the year you have to reconstruct spending you made before you knew any of this mattered. Save the receipts from here on, keep LLC money and personal money separate where you can, and next April is a twenty-minute job.

Key Takeaways

• A foreign-owned single-member LLC almost always has a Form 5472 obligation in its formation year, because forming the entity moves money between owner and LLC.
• Amounts paid in connection with the formation of the entity, plus contributions and distributions, are reportable in Part V.
• Your first tax year runs from the formation date to December 31; a DE uses its owner’s US tax year or, if none, the calendar year.
• The first deadline is April 15 of the following year regardless of formation month a November LLC gets no earlier and no later date.
• Line 1j in Part I is the initial-year checkbox: tick it on your first Form 5472 only.
• There is no dollar threshold a $50 state fee paid personally is as reportable as a $50,000 wire.
• “We haven’t started trading” is not an exemption; the form tracks owner-entity transactions, not sales.
• You need an EIN to file, but not an ITIN; use a reference ID number for the foreign owner if you have no US tax ID.
• If the EIN is running late, file Form 7004 by April 15 to extend to October 15.
• The package cannot be e-filed fax to (855) 887-7737 or mail to Ogden, UT, and keep the confirmation. The penalty for getting this wrong is $25,000.
