Form 5472: $25,000 Penalty for Non-Resident LLCs (Filing Guide)

The penalty for missing Form 5472 is $25,000 per form, per year. Every foreign-owned single-member LLC must file Form 5472 annually with the IRS, attached to a pro forma Form 1120. Due April 15, extendable to October 15. Revenue and profit are irrelevant — if your LLC existed and any money moved between you and the entity, the filing obligation was triggered. CPA preparation costs $650 to $1,200.

April 2026 update: The Form 5472 deadline for tax year 2025 is April 15, 2026. You can extend to October 15 by filing Form 7004 before the April deadline. CPA quotes for standalone 5472 filing currently range from $650 to $1,200 based on recent discussions in r/smallbusiness and r/tax. For zero-revenue single-member LLCs, the self-filing workflow is also viable — see the DIY tax filing guide for the structural walkthrough and the thresholds where DIY stops making sense.

I didn't know about Form 5472 until a founder in my network got hit with the penalty. He'd done everything right -- formed his LLC, got the EIN, opened a Mercury account, started invoicing clients. Nobody mentioned Form 5472. Eighteen months later, a $25,000 notice showed up.

What is Form 5472?

Form 5472 is an IRS information return. The full title mentions "25% Foreign-Owned U.S. Corporation" -- which sounds like it wouldn't apply to your single-member LLC. It does. The IRS treats foreign-owned single-member LLCs as corporations for this specific reporting purpose under Treasury Regulation 1.6038A-1(c)(1).

The form captures any money that moved between you and your LLC:

• Capital contributions — money you put in
• Distributions — money you took out
• Loans — borrowed or lent between you and the LLC
• Rent or lease payments — the LLC using your personal assets or the reverse
• Service payments — you paying the LLC, or it paying you
• Any other monetary transaction between the LLC and a 25%+ foreign owner

If you wired $500 to fund the LLC's bank account, that was a reportable transaction. The filing obligation started that day.

Who has to file Form 5472?

You file Form 5472 if your US LLC checks three boxes:

1. Single-member (or treated as a disregarded entity)
2. Owned by a foreign person -- not a US citizen, no green card, doesn't meet the substantial presence test
3. Had at least one reportable transaction during the tax year

That third one trips people up. You don't need revenue. A single capital contribution counts.

The form gets attached to a pro forma Form 1120 (US Corporation Income Tax Return). The 1120 itself is all zeros -- no income, no tax. It exists only as the vehicle to carry Form 5472. Both forms go in together as one submission.

When is Form 5472 due?

April 15 following the calendar year. Form 5472 for 2025 is due April 15, 2026.

You can extend six months to October 15 by filing Form 7004 before the April deadline. Technically this extends the time to file, not to pay -- but since most foreign-owned single-member LLCs owe zero US tax, the distinction is academic.

Here is the part that catches people: the filing obligation starts the year you formed the LLC. Not the year you earned revenue. I know a founder who incorporated in September, had zero clients by December, and still owed a Form 5472 for that year because he'd wired $500 into the business account.

The $25,000 penalty: how it works

IRC Section 6038A(d) prescribes $25,000 for:

• Failure to file -- you never submitted it
• Late filing -- submitted after the deadline, extension included
• Substantially incomplete filing -- submitted but missing material information

Per form, per year. One LLC, two missed years = $50,000. Two LLCs, one missed year each = also $50,000.

It gets worse. After the initial $25,000, the IRS sends a notice demanding compliance. If you still haven't filed 90 days later, an additional $25,000 accrues every 30 days. No cap.

Penalty timeline example

These are statutory penalties. The IRS has the authority to assess them without proving intent or harm.

What triggers IRS awareness?

Multiple channels, and the IRS is getting better at connecting them.

EIN records. When you applied for an EIN, the IRS recorded that the responsible party is a foreign person. They cross-reference that against filed returns. A foreign-owned EIN with no Form 1120 + Form 5472 on file is a straightforward data match. (The EIN vs. ITIN distinction matters here -- the EIN creates the entity-level obligation.)

Bank account reporting. US banks report account holder information to the IRS. An LLC bank account with a foreign owner that shows no corresponding tax filing is a flag.

FATCA and CRS. Under CRS and FATCA, financial institutions in participating countries share account data with tax authorities. If you have bank accounts internationally and no US filing, that gap is visible across borders.

State formation records. Stripe Atlas, Firstbase, Doola -- all of them file formation documents with state secretaries of state. Those records are accessible to the IRS.

None of this is instant. But the automation has improved sharply over the past few years. The gap between "I formed my LLC" and "the IRS noticed I didn't file" is shrinking. The documentation gap analysis shows what authorities actually see when they pull up a founder's records.

Can the penalty be reduced or removed?

Yes, but nothing is guaranteed.

Reasonable cause. You need to show the failure wasn't willful neglect. Relying on a tax professional who failed to mention Form 5472 is a stronger argument than "I didn't know." But even "I didn't know" isn't automatically disqualifying -- the IRS looks at the totality of circumstances.

First-time penalty abatement. This program exists for common penalties (failure-to-file, failure-to-pay under IRC 6651). Form 5472 penalties fall under IRC 6038A, so the first-time abatement doesn't automatically apply. Some practitioners have gotten abatement through reasonable cause arguments, but it's case-by-case.

Streamlined filing. For US persons living abroad who were non-willful, the Streamlined Filing Compliance Procedures offer a path to compliance with reduced penalties. This covers delinquent tax returns and information returns, including Form 5472.

Bottom line: filing late is always cheaper than not filing at all.

How much does it cost to file Form 5472?

$500-900 a year to avoid a $25,000 penalty. That math is straightforward.

When I set up compliance for my own LLC, the hardest part was getting the right documents to my CPA. Most founders don't have clean records of what moved between them and the LLC. What your CPA needs to see covers the specifics.

Multi-member LLCs: a different filing obligation entirely

Everything above applies to single-member foreign-owned LLCs. If the LLC has two or more members, the tax classification changes from disregarded entity to partnership. The filing obligation shifts from Form 5472 + pro forma 1120 to Form 1065 (US Return of Partnership Income), with individual Schedule K-1s for each member.

Form 1065 is a more complex return with a different deadline — March 15, not April 15. The penalty for late filing is $220 per partner per month (up to 12 months), and the return itself requires allocation of income, deductions, and credits across members. Tax practitioners identify this as a common structural mistake: non-resident founders adding a co-founder or investor to their LLC without realizing it triggers an entirely different (and more expensive) compliance regime.

What this means for new LLC owners

If you formed a US LLC as a non-resident and haven't filed Form 5472, the obligation already exists. It doesn't start when you earn revenue or take a distribution. It started the day you funded the bank account.

The penalty is the same whether you moved $500 or $500,000. That asymmetry is what makes Form 5472 dangerous -- it punishes the smallest, simplest LLCs just as hard as complex corporate structures. And the founders running those small LLCs are the ones least likely to know about it.

The risk check flags whether your LLC structure has a Form 5472 gap, along with other compliance obligations tied to your specific cross-border setup.

Key Takeaways

• The IRS penalty for a missing or late Form 5472 is $25,000 per form, per year. A founder who misses two years faces $50,000+ in accumulated penalties before any other consequence.
• Every foreign-owned single-member LLC must file Form 5472 annually with a pro forma Form 1120, regardless of whether the LLC had revenue. The obligation starts from the year of formation.
• Filing costs $500-2,000/yr through a CPA, $899/yr through Firstbase, or $1,999/yr through Doola's Total Compliance tier. None of the major formation services include it in their base formation price.
• Penalty abatement is possible through reasonable cause or streamlined filing, but it is discretionary. Filing late is always less expensive than not filing at all.

Frequently Asked Questions

Do I need to file Form 5472 if my LLC had no income?

Yes. The trigger is "reportable transactions," not income. If you put money into the LLC -- even $100 as a capital contribution -- that counts. Paying the LLC's expenses from personal funds counts. Any monetary transfer between you and the LLC counts. Zero revenue is irrelevant.

How do I file Form 5472 for my non-resident LLC?

Attach it to a pro forma Form 1120 (all zeros for income and tax -- the 1120 is just the filing vehicle). Mail both to the IRS address in the Form 1120 instructions, or e-file through an authorized provider. Most non-resident founders use a CPA or a compliance service like Firstbase ($899/yr) or Doola ($1,999/yr). The expat tax service comparison covers which providers handle Form 5472 and at what price.

Can I file Form 5472 late to avoid the full penalty?

Late is better than never. The IRS assesses the $25,000 when they discover non-filing, but a late filing with a reasonable cause explanation can lead to abatement -- at their discretion. Once they send a formal notice, you get a 90-day window before additional penalties start stacking. Filing within that window stops the escalation, even if you're late relative to the original deadline.

Does Stripe Atlas or Firstbase file Form 5472 for me?

Stripe Atlas does not -- at any price point. You're on your own. Firstbase offers it as an add-on at $899/yr. Doola includes it in their Total Compliance tier at $1,999/yr. None of the three include Form 5472 in the base formation price.
