Form 5472 risk assessment

Step 1: Do you owe Form 5472?

Form 5472 is required if your LLC meets ALL three:

• The LLC is a US-formed entity (Delaware, Wyoming, etc.) - YES if you are reading this.
• The LLC is a single-member disregarded entity (default treatment for single-member LLCs).
• The single member is a non-US person (non-citizen, non-resident).

If you are a non-resident foreign founder of a single-member Delaware LLC, you owe Form 5472 every year - even with zero US-source income, even with zero transactions, even if the LLC was dormant.

Multi-member LLCs default to partnership tax treatment and file Form 1065 instead. C-corp-electing LLCs file Form 1120 (full return, not pro forma). Form 5472 specifically targets the single-member-disregarded case.

Step 2: What counts as a reportable transaction

A reportable transaction under Treasury Regulation § 1.6038A-2(b) is any transaction between the LLC and the foreign owner (or a foreign-related party). The most common triggers:

Risk score

Count your risk factors:

• 1 point: First year of operation - higher risk of forgetting to file.
• 1 point: Owner contributed capital during the year.
• 1 point: LLC distributed funds to owner.
• 1 point: Owner paid LLC expenses personally (bank fees, registered agent renewal, software).
• 2 points: Loans between LLC and owner during the year.
• 2 points: Service or royalty payments between LLC and foreign-related entity.
• 3 points: Multiple foreign-related entities transacting with LLC.

0-1 points: Standard filing. Prepare Form 5472 with simple capital-contribution disclosure.
2-4 points: Standard filing with multiple transactions. Engage CPA for accurate disclosure.
5+ points: Higher complexity. Engage CPA with cross-border experience; transfer-pricing documentation may apply.

What to file

1. Form 5472 - the disclosure form itself, listing reportable transactions and the foreign owner.
2. Pro forma Form 1120 - a stripped-down version showing LLC name, EIN, and address, with Form 5472 attached.
3. Both filed together, due April 15 (or October 15 with Form 7004 extension).

Where to find help

CPAs experienced with foreign-owned single-member LLCs typically charge $500-$1,200 for the annual Form 5472 + pro forma 1120 filing. Higher-complexity situations (multiple related entities, transfer pricing) cost $1,500-$3,000.

What does this Form 5472 risk assessment actually compute?

This tool answers two linked questions that most non-resident founders confuse. The first question is binary and unforgiving: does your LLC owe Form 5472 at all? The second is a graded measurement: given your obligation, how many reportable transactions occurred during the tax year, and how complex is your disclosure likely to be? The calculator separates these on purpose. A founder can answer "yes" to the obligation test and still have a near-empty form because nothing moved between the owner and the LLC. Another founder can have a thick disclosure because money flowed back and forth all year. Both owe the form. Only one faces a complicated preparation job.

The output is not a dollar figure. It is a risk profile expressed as a point score plus a plain reading of whether you can file a simple return or need a cross-border CPA. The $25,000 figure that anchors the page is the penalty for not filing at all, not a sliding scale you compute from inputs. That is a deliberate framing choice. Under-counting your transactions rarely triggers the $25,000 hit on its own, but failing to file the form when you owed it does. So the assessment pushes you toward the safe default: when in doubt, file. The score exists to tell you how much help you need to file accurately, not whether to file. Read the result as a staffing decision rather than a tax bill, and you will use it the way it was designed to be used.

Who is the "foreign owner" the form is built around?

The obligation hinges on a person, not a place. Your LLC can sit in Delaware, hold a US EIN, and bank with Mercury or Wise, yet the filing trigger is whoever owns the membership interest. If that single member is a non-US person, meaning not a citizen and not a resident for tax purposes, the disregarded LLC becomes a reporting entity. The form treats the LLC as a window into transactions between a US-formed shell and its foreign owner so the IRS can see cross-border money movement that would otherwise be invisible on a disregarded entity that files no income return of its own.

This is why the assessment asks about your status before it asks about money. A common error is assuming that paying US taxes elsewhere, or having no US-source income, removes the obligation. It does not. The list below captures the people and arrangements that keep you inside the rule:

• A non-resident individual owning 100% of a single-member LLC, even with zero income.
• A foreign company owning the LLC, where the parent is the reportable foreign related party.
• A founder who became non-resident mid-year but owned the LLC while non-resident.
• An owner whose only US connection is the LLC itself and its US bank account.
• A dormant LLC with no operations but a formation contribution from its foreign owner.

How do I read the Step 1 obligation test?

Step 1 is a three-condition gate, and all three must be true at once. The LLC must be US-formed, which it is if you registered in Delaware. It must be a single-member disregarded entity, which is the default for a one-owner LLC that has not elected corporate taxation. And the single member must be a non-US person. Read this as an AND, never an OR. If any one condition fails, you are out of the Form 5472 regime, though you may land in a different one. The test is intentionally narrow because it targets a specific structure that Congress closed in 2017: the invisible single-member shell owned from abroad.

The trap inside Step 1 is the disregarded-entity condition. Many founders do not realize their LLC is disregarded by default because they never filed an election. Others assume that opening a business bank account or earning revenue changes the classification. It does not. Classification changes only when you file Form 8832 to elect corporate treatment, or Form 2553 for an S election that a non-resident generally cannot make anyway. So for the typical reader here, the disregarded box is checked automatically. If you added a second member during the year, the LLC may have become a partnership, which flips you to Form 1065 and out of the 5472-with-pro-forma-1120 path. Note your structure as of the relevant dates before trusting the gate.

How do I read the Step 2 reportable-transaction table?

Step 2 turns the gate into an inventory. The table sorts common money movements into reportable and not reportable. The dividing line is relatedness. A transaction is reportable when it runs between the LLC and its foreign owner, or between the LLC and any foreign party related to that owner. A transaction is not reportable when it runs between the LLC and an unrelated US vendor or an unrelated customer. So your $40 monthly software subscription paid to a US company from the LLC account is not reportable, but the same $40 is reportable if you paid it personally from your own pocket on the LLC's behalf, because that is value flowing from owner to entity.

Read each row as a yes or no for your year, not as a dollar test. Most reportable categories carry no minimum threshold, which surprises founders who expect a de minimis floor. The categories that almost always apply to a first-year non-resident LLC are:

• Capital contribution from owner to LLC, including the cash you used to open the bank account.
• Distribution from LLC to owner, including any transfer back to your personal account.
• Owner paying an LLC expense personally, such as a registered agent renewal or bank fee.
• Loans either direction between owner and LLC, which carry extra weight in the score.
• Service or royalty payments to a foreign-related entity you also control.

How does the risk score translate into action?

The score assigns points to factors that raise the chance of an inaccurate or missed filing. First year of operation earns a point because forgetting is most common when the habit has not formed. Contributions, distributions, and personally paid expenses each add a point because each is a distinct line you must disclose correctly. Loans add two points because they involve balances, directions, and sometimes interest, all of which the form wants itemized. Service or royalty payments to a related foreign entity add two points because they raise valuation questions. Multiple foreign-related entities add three because that is where transfer-pricing scrutiny begins.

The bands then map to staffing. A score of 0 to 1 means you can most likely prepare a simple Form 5472 with a single capital-contribution line and a pro forma 1120 shell. A score of 2 to 4 means the form has several moving parts and a CPA will save you from misclassifying a row. A score of 5 or more means you have entered the territory where cross-border experience matters and transfer-pricing documentation may be required. Use the band as a hiring signal. Do not read a low score as permission to skip the form, and do not read a high score as a reason to delay until the structure feels simpler. The deadline does not move because your facts are messy.

A worked example: the dormant first-year LLC

Consider a founder in Lisbon who formed a Delaware LLC for $110, paid the Delaware franchise tax of $300 due June 1, opened a Mercury account, and then did nothing. No revenue, no customers, no invoices. It feels like there is nothing to report. Run the assessment anyway. Step 1 returns yes on all three conditions: US-formed, single-member disregarded, non-resident owner. The obligation exists despite the silence. Step 2 then asks what moved. The founder wired in $2,000 to open the bank account. That is a capital contribution from owner to LLC, which is reportable at any amount. The franchise tax, if paid from the founder's personal card rather than the LLC account, is also a reportable owner-paid expense.

So the dormant LLC has at least one and possibly two reportable transactions, and a risk score of 2 to 3: one point for first year, one for the contribution, and one if the owner paid an LLC expense personally. The lesson is that "dormant" almost never means "zero transactions." The act of funding the LLC is itself reportable. This founder still files Form 5472 with a pro forma 1120, lists the contribution, and avoids the $25,000 penalty that attaches to not filing. The form is short, but it is mandatory, and the worked example exists to break the instinct that no business activity equals no obligation.

A worked example: the active LLC with money flowing both ways

Now take a founder in Dubai whose Delaware LLC earned $90,000 from unrelated US and European clients, paid software and contractor costs from the LLC account, and moved $50,000 back to a personal account across the year. The instinct is that the $90,000 of revenue dominates the form. It does not. Revenue from unrelated customers is not a reportable transaction, so it never appears on Form 5472 as a line. What the form cares about is the owner-to-LLC and LLC-to-owner flow. The $50,000 in transfers back to the founder are distributions, reportable at any amount, and any startup funds the founder injected are contributions.

Score this one carefully. First year adds a point if applicable. The distribution adds a point. A startup contribution adds a point. If the founder also lent the LLC money to cover a cash gap and the LLC repaid it, that is loans in both directions, adding two points. The total lands at 4 to 5, which pushes the founder into the "engage a CPA" band. The non-reportable $90,000 still matters for the founder's home-country taxes and for any US filing the facts might trigger, but on Form 5472 it is invisible. The example teaches the counterintuitive core of the rule: gross revenue size does not drive the form, related-party money movement does.

What is the underlying rule and where does it come from?

Form 5472 lives in the Internal Revenue Code and its regulations, with the reportable-transaction definition sitting at Treasury Regulation section 1.6038A-2(b). Before 2017, a foreign-owned single-member LLC treated as disregarded filed nothing federally, which made it a quiet vehicle for moving money without US visibility. Regulations finalized in 2016 and effective for tax years beginning on or after January 1, 2017 closed that gap by treating the disregarded LLC as a domestic corporation for the limited purpose of the 5472 reporting and record-keeping rules. That is why you file a pro forma 1120 even though your LLC is not a corporation: the regulation borrows the corporate filing vehicle to carry the disclosure.

The record-keeping piece is easy to miss. The same regulation that requires the form requires you to keep books and records sufficient to establish the accuracy of the reported transactions. A founder who files a clean form but cannot show the bank statements and contribution records behind it has only done half the job. Keep a simple ledger of every owner-to-LLC and LLC-to-owner movement, dated and described, with the matching bank entry. When the form asks for amounts by category, you transcribe from that ledger rather than reconstructing a year from memory. The rule rewards contemporaneous records and punishes the absence of them through the same penalty structure that punishes non-filing.

What exactly is the $25,000 penalty, and how does it multiply?

The penalty for failing to file a required Form 5472, or for failing to keep the required records, is $25,000 per occurrence. The word occurrence does the damage. Each tax year you owed the form and did not file it is its own occurrence, so a founder who ignored the obligation for three years is looking at three separate $25,000 exposures, not one. The penalty also applies to a substantially incomplete filing, which means a form filed on time but missing required transactions can still draw the charge. There is an additional penalty mechanism if the failure continues after the IRS notifies you, so silence after notice compounds the problem rather than freezing it.

Because the penalty is fixed rather than proportional, it falls hardest on the smallest LLCs. A dormant entity that owed a two-line form faces the same $25,000 as an active one that owed a page of disclosures. That asymmetry is the entire reason this assessment leans toward filing. The math is stark: the form costs a few hundred to low thousands of dollars to prepare, while skipping it risks $25,000 per year. If you have already missed one or more years, do not quietly file back forms without advice. Speak to a tax attorney about voluntary disclosure and first-time penalty abatement first, because how you re-enter compliance affects whether the penalty sticks.

What are the most common mistakes founders make here?

The mistakes cluster around a single false belief: that activity level determines the obligation. Founders skip the form because the LLC was dormant, because there was no US income, because they already pay tax at home, or because the amounts felt too small to matter. Each of those is wrong under this rule. The obligation attaches to the structure and the owner's status, and the reportable transactions have no minimum threshold. Another cluster involves classification: assuming a bank account or revenue converted the LLC away from disregarded status, when only a filed election does that. A third cluster is the deadline, which founders confuse with their home-country tax calendar.

Here are the errors worth checking against before you file:

• Treating a dormant year as a no-filing year when a funding contribution occurred.
• Omitting expenses you paid personally on the LLC's behalf, which are reportable.
• Reporting unrelated customer revenue on the form, where it does not belong.
• Forgetting that loans in either direction must be disclosed with their balances.
• Missing the April 15 deadline because it differs from a home-country filing date.
• Filing the form but failing to keep the bank records that support each line.

What edge cases change the answer?

Several fact patterns sit at the boundary of the rule and deserve a closer look. A mid-year change of ownership status is one: if you were a US resident for part of the year and non-resident for the rest, the question becomes your status during the period you owned the interest and during which transactions occurred. A second edge case is the addition or removal of a member. Going from one member to two can convert the LLC to a partnership filing Form 1065, while going from two to one can drop you into the single-member 5472 regime mid-year. A third is a foreign parent company structure, where the reportable related party is the parent and possibly other entities under common control.

Currency and timing create quieter edges. A contribution made in euros and recorded in dollars needs a defensible exchange rate on the transaction date, not a year-end average chosen for convenience. A transfer initiated in December but settled in January raises a year-attribution question that your ledger should resolve consistently. A reimbursement that nets a contribution against a distribution should still be reported gross, because the form wants the flows by category rather than a single net number. None of these edges remove the obligation. They change what goes on which line and in which year, which is exactly the kind of judgment that pushes a higher-scoring founder toward professional help rather than a do-it-yourself form.

What should I do with my result?

Treat the result as a two-part instruction. The Step 1 answer tells you whether to file, and for the typical reader here it will be yes. Act on that first, because the filing decision is where the $25,000 exposure lives. The Step 2 inventory and the risk score then tell you how to file: alone with a simple form, or with a CPA who can classify your transactions correctly. A 0 to 1 score supports a self-prepared form for a confident founder who keeps clean records. A 2 to 4 score is the sweet spot for hiring a preparer who handles foreign-owned LLCs as routine work. A 5 or higher score means cross-border experience and possible transfer-pricing documentation, so choose accordingly.

Whatever the score, three actions follow for every reader. Build the transaction ledger now so next year's assessment is a transcription job rather than a reconstruction. Mark the April 15 deadline, and the October 15 extended date if you file Form 7004, on the same calendar you use for everything else so it does not slip. And if you suspect you missed a prior year, stop and get advice before filing back forms, because the path back into compliance is itself a decision with penalty consequences. The assessment has done its job when it has converted a vague worry into a concrete filing plan with a deadline and a staffing choice attached. Re-run it each year, because your facts and therefore your score will move.
