The short answer
Key takeaways
An IRS audit, or examination, is a formal review of whether your foreign-owned LLC filed Form 5472 correctly and kept records under IRC section 6038A. For a foreign-owned single-member LLC, the audit usually centers on whether the form was filed at all and whether every reportable transaction was reported.
An audit is not an accusation of fraud. It is a verification process. The IRS picks a return or an entity and asks you to substantiate what you reported — or to explain why you did not file at all. For a foreign-owned single-member LLC, the relevant law is IRC section 6038A, which imposes both a filing duty (Form 5472 with a pro forma 1120) and a separate record-keeping duty.
Most 6038A examinations begin in one of two ways: the IRS notices that an EIN was issued to a foreign-owned LLC but no Form 5472 was ever filed, or a filed return looks incomplete. Either path can lead to the $25,000 penalty under IRC 6038A(d) plus a demand for the underlying records. A clean, complete filing rarely escalates beyond a routine document request.
These three are not the same. A notice is an automated letter (for example, a CP-series notice) flagging a problem. An audit or examination is a deeper review assigned to a revenue agent. A penalty assessment is the IRS formally charging the $25,000. You can face a penalty without a full audit, and an audit can close with no change. Knowing which one you received decides how urgently you must respond.
| What you received | What it means | Typical first step |
|---|---|---|
| Notice (e.g. CP letter) | Automated flag of a possible 6038A issue | Read it, note the response deadline, gather records |
| Examination / audit letter | A revenue agent will review the return and records | Engage a licensed CPA, EA, or attorney |
| Penalty assessment | The IRS has charged the $25,000 penalty | Consider reasonable-cause relief with a professional |

A 6038A audit reviews whether the LLC filed Form 5472 on time, whether each reportable transaction was reported accurately, and whether the entity kept the required books and records. The IRS may request bank statements, the operating agreement, loan documents, and a transaction ledger going back several years.
In a 6038A examination, a revenue agent works through a predictable checklist. First, did the LLC file Form 5472 with a pro forma Form 1120 for each open year? Second, does the form list the foreign owner and every related-party reportable transaction — capital contributions, loans, repayments, distributions, and amounts paid for services? Third, can the LLC produce records that substantiate those numbers?
The records requirement is its own obligation under IRC 6038A(a). If the IRS asks for documents and the LLC cannot produce them, a separate $25,000 penalty applies for failure to maintain records — independent of any penalty for failing to file the form. That is why clean bookkeeping turns an audit into a routine exchange of paperwork rather than a crisis.
| Document | What it proves | Why the IRS wants it |
|---|---|---|
| Bank statements (all LLC accounts) | Money in and out of the LLC | To match reported reportable transactions |
| Operating agreement | Ownership and capital structure | To confirm the 25% foreign owner |
| Loan / contribution agreements | Nature of owner funding | To classify Part V / Part VI items |
| Invoices and service contracts | Amounts paid for services or rent | To verify Part IV monetary transactions |
| Transaction ledger | Summary of related-party dealings | To reconcile the figures on Form 5472 |

The lookback can be long. Because an unfiled information return has no statute of limitationsunder IRC 6501(c)(8), the IRS can examine years that ordinarily would be closed. Keeping records for the life of the entity plus several years is the only safe practice.
Form 2848 is the IRS Power of Attorney and Declaration of Representative. It names a licensed CPA, enrolled agent, or attorney and authorizes them to receive your notices, talk to the IRS, and represent you in the audit. Without a valid Form 2848 on file, no one can act for you before the IRS.
Form 2848 is the single document that gives a representative authority to act for you. You list the tax matter (for example, Form 5472 / 1120 for specific years), name the representative and their credential, and sign it. The representative also signs the Declaration of Representative section, certifying they are eligible to practice. Once the IRS processes it, the agent communicates with the representative instead of you.
A related but different form is Form 8821, Tax Information Authorization. Form 8821 lets someone receive your tax information but does not let them represent you or argue your case. For an actual audit you need Form 2848. A non-resident owner can sign Form 2848 from abroad and mail or fax it — there is no requirement to travel to the United States.
| Feature | Form 2848 (Power of Attorney) | Form 8821 (Information Authorization) |
|---|---|---|
| Lets a person represent you | Yes | No |
| Lets a person receive your records | Yes | Yes |
| Can argue your case in an audit | Yes | No |
| Who can be named | Attorney, CPA, EA (and limited others) | Anyone you designate |

A foreign owner without a Social Security Number uses their LLC's EIN and their own foreign tax identification details where required. Once signed and filed, the representative can request the audit file, respond to information document requests, and attend any conference — all without the owner leaving their home country.
Only three credentialed groups have unlimited rights to practice before the IRS: attorneys, certified public accountants (CPAs), and enrolled agents (EAs). They can represent you in any audit, appeal, or collection matter. Unenrolled return preparers have only limited rights and cannot represent you in a Form 5472 audit.
Representation before the IRS is regulated by Treasury Circular 230. Three groups hold unlimited practice rights and can represent any taxpayer on any matter: licensed attorneys, CPAs, and enrolled agents. An enrolled agent is a federally licensed tax practitioner who has passed the IRS Special Enrollment Examination or has qualifying IRS experience.
Everyone else has limited or no rights. An unenrolled preparer who actually prepared a return may, in narrow cases, discuss that specific return, but cannot represent you in an examination, appeal, or collection action. A bookkeeper or formation agent has no representation rights at all. This is why a filing service and a representative are different things.
| Practitioner | Practice rights | Can handle a 6038A audit? |
|---|---|---|
| Tax attorney | Unlimited | Yes |
| CPA (certified public accountant) | Unlimited | Yes |
| Enrolled agent (EA) | Unlimited | Yes |
| Unenrolled return preparer | Limited to returns they prepared | No |

form5472.tax does not represent clients before the IRS. We are a filing service: we prepare and file accurate Form 5472 and pro forma 1120 packages. If you are under examination, retain a licensed tax attorney, CPA, or EA who will file Form 2848 and represent you directly.
No. form5472.tax does not represent clients before the IRS. We prepare and file accurate Form 5472 and pro forma 1120 returns so an audit is less likely. If you are audited, you must engage a licensed CPA, enrolled agent, or tax attorney who holds a valid Form 2848 to represent you.
It is important to be direct about this. form5472.tax is a filing service, not a representation firm. We do not appear before the IRS, sign Form 2848 as your representative, or argue your case in an examination. We do not provide penalty-abatement representation or audit defense. Those services require credentials we do not claim, and offering them without a license would be improper.
What we do is the most effective audit prevention available: prepare a complete, accurate, on-time return every year. The majority of 6038A problems come from non-filing or incomplete filing. Removing those errors removes the most common reasons the IRS opens a Form 5472 examination in the first place. We file that package for a flat $299.
If you have already received an audit or examination letter, please consult a licensed tax attorney, CPA, or enrolled agent without delay. They can evaluate your facts, file Form 2848, and represent you directly. You can read our neutral overviews of related relief topics, such as Form 843 penalty abatement and IRS voluntary disclosure, to understand the landscape before you speak with a professional.
Audit risk is low for a foreign-owned LLC that files a complete Form 5472 and pro forma 1120 on time and keeps records. Most 6038A examinations start from a non-filing or an incomplete return, which the IRS treats as a failure to file and which can trigger the $25,000 penalty.
The IRS does not publish a precise audit rate for Form 5472, but the pattern is consistent: most 6038A problems begin with something the IRS can see automatically. An EIN was issued to a foreign-owned LLC, but no Form 5472 was ever filed. Or a form arrived missing a part, missing the pro forma 1120, or filed after the deadline. Each of these flags the entity.
By contrast, a complete and timely package gives the IRS little to question. The form is an information return — there is no tax computation to dispute for a disregarded entity. When the numbers reconcile with the LLC's bank activity and the records are available, an examination, if it opens at all, usually closes quickly with no change.
| Factor | Effect on audit risk | What to do |
|---|---|---|
| No Form 5472 filed despite having an EIN | Raises risk sharply | File now, consider catch-up filing |
| Incomplete or wrong-revision form | Raises risk | File the current revision, all required parts |
| Missed April 15 / October 15 deadline | Raises risk | File late immediately to stop accrual |
| Complete, on-time, reconciled filing | Lowers risk | Keep filing every year, keep records |
| Clean records for every transaction | Lowers risk | Retain bank statements and agreements |

If you have unfiled years, the priority is to fix them before the IRS finds them. See what to do if you missed Form 5472 and the catch-up filing process for the steps.
Under IRC 6038A(a) you must keep records sufficient to verify every reportable transaction on Form 5472: bank statements, the operating agreement, loan and contribution documents, invoices, and a ledger. Failure to maintain these records carries its own $25,000 penalty, separate from the filing penalty.
Record-keeping is half of the 6038A obligation and the part founders most often overlook. The statute requires the LLC to maintain books and records that substantiate the amount and nature of each reportable transaction with a related party. For a small LLC that means a tidy file: bank statements for every account, the operating agreement, any loan or capital-contribution agreement, invoices for services or rent, and a simple ledger that maps each entry to a line on Form 5472.
The penalty for missing records is severe and independent. If the IRS requests documents in an audit and the LLC cannot produce them, IRC 6038A(d) imposes a $25,000 penalty for failure to maintain records — on top of any penalty for failing to file. Because there is no statute of limitations on the underlying information return, the IRS can reach back many years, so records should be kept for the life of the entity plus several years.
| Record | Keep for | Maps to |
|---|---|---|
| Bank statements (all accounts) | Life of entity + several years | All reportable transactions |
| Operating agreement | Permanently | Part II — 25% foreign owner |
| Capital contribution / loan agreements | Permanently | Part V / Part VI |
| Service invoices and contracts | Life of entity + several years | Part IV |
| Annual transaction ledger | Permanently | Reconciliation of the whole form |

The agent-of-the-owner rule also matters. In some cases the foreign owner must authorize the US entity to act as their agent for IRS document requests, executed through a written authorization or Form 2848-style appointment. Clean records plus a clear agency authorization turn a stressful audit into a routine production of documents.
A 6038A audit can produce a $25,000 penalty for failing to file Form 5472 and a separate $25,000 penalty for failing to keep records. After a 90-day notice, an extra $25,000accrues every 30 days the form stays unfiled, with no cap and no statute of limitations.
The penalties under IRC 6038A are among the harshest information-return penalties in the US tax code. The base failure-to-file penalty is $25,000 per form, per year, per entity. There is no maximum cap and, because the return is an information return, no statute of limitations under IRC 6501(c)(8). A year missed long ago can still be assessed today.
The penalty also compounds. If the IRS issues a notice of failure and the form is still not filed within 90 days, an additional $25,000 applies for each 30-day period the failure continues. Separately, failing to maintain records under 6038A(a) carries its own $25,000charge. A single audit can therefore surface multiple stacked penalties.
| Trigger | Penalty | Legal basis |
|---|---|---|
| Failure to file Form 5472 (per form, per year) | $25,000 | IRC §6038A(d)(1) |
| Failure to maintain required records | $25,000 | IRC §6038A(d)(1) |
| Continued failure after a 90-day notice | $25,000 per 30 days | IRC §6038A(d)(2) |
| No statute of limitations on the return | Years stay open | IRC §6501(c)(8) |

Penalties may be abated for reasonable cause, but that is a representation matter for a licensed professional, not a filing service. See the full Form 5472 penalty breakdown and the underlying IRC 6038A rules for the statutory detail.
Sometimes. The IRS may abate a 6038A penalty if you show reasonable cause — a good-faith reason for the failure that was not willful neglect. Relief is requested through a reasonable-cause statement or Form 843, and is best argued by a licensed representative under a Form 2848.
The IRS can waive a penalty when the taxpayer demonstrates reasonable cause and an absence of willful neglect. Reasonable cause means you exercised ordinary business care but still failed — for example, you relied on incorrect professional advice, or a serious personal event prevented timely filing. A bare statement that you did not know about Form 5472 is rarely enough on its own.
Relief is requested either through a written reasonable-cause statement attached to a late filing or through Form 843, Claim for Refund and Request for Abatement, after a penalty is assessed. Because the outcome depends on how the facts are framed and argued, this is a representation matter. A licensed CPA, EA, or attorney files Form 2848 and presents the case.

If you have multiple unfiled years, options range from a quiet catch-up filing to the formal IRS voluntary disclosure program for more serious cases. Which path fits depends on your facts and is a decision for a licensed tax attorney or CPA — not a filing service.
Foreign founders sometimes discover they have several unfiled Form 5472 years. The right response depends on the severity and on whether the IRS has already contacted you. For a straightforward oversight with no IRS contact, a prompt catch-up filing of the missing years, with a reasonable-cause statement where appropriate, is often the practical route.
For more serious situations — large amounts, several years, or potential exposure beyond Form 5472 — the IRS offers a formal voluntary disclosure process designed to bring non-compliant taxpayers back into the system on defined terms. Entering that program is a significant legal decision with real consequences, and it should be evaluated by a licensed tax attorney who can assess privilege and exposure.
form5472.tax does not represent clients before the IRS and does not advise on voluntary disclosure strategy. We can prepare accurate returns for the years you choose to file. For the neutral overviews, see IRS voluntary disclosure, what to do if you missed Form 5472, and the late-filing penalty.
A 6038A audit typically runs in five stages: an opening notice, an information document request, your document production, the agent's review and findings, and either a no-change closing or a penalty assessment you can appeal. A representative handles each stage under Form 2848.
While every examination differs, a Form 5472 audit usually follows a recognizable sequence. Knowing the stages helps you respond calmly and on time. The single most damaging mistake is missing a response deadline, which can convert a manageable review into a default penalty assessment.
| Stage | What happens | Your move |
|---|---|---|
| 1. Opening letter | IRS notifies you of the examination and the years | Note deadlines; engage a CPA/EA/attorney |
| 2. Information Document Request (IDR) | Agent lists the records they want | Gather bank statements, agreements, ledgers |
| 3. Document production | You submit records by the deadline | Submit complete, organized documents |
| 4. Review and findings | Agent reconciles records to the form | Representative answers questions, clarifies |
| 5. Closing | No-change letter or penalty assessment | Accept, or appeal with your representative |

At the closing stage, an unfavorable result is not the end. You generally have the right to take the matter to IRS Appeals, an independent office that reviews the agent's determination. Your licensed representative manages the appeal under the same Form 2848. Throughout, accurate prior filings and clean records are your strongest evidence.
Prevent most audits by filing a complete, accurate Form 5472 with a correct pro forma 1120 on time every year, using the current revision, and keeping records of every reportable transaction. Non-filing and incomplete filing cause the majority of 6038A examinations.
Audit prevention is mostly about removing the obvious triggers. File every year — even a zero-income LLC almost always has a reportable transaction because funding the LLC counts. Attach the pro forma Form 1120; Form 5472 cannot stand alone. File the current revision of the form, because an outdated version can be treated as substantially incomplete and therefore as a failure to file.
File on time. The deadline is April 15, extended to October 15 with Form 7004. Because a foreign-owned disregarded entity cannot e-file, mail the package to P.O. Box 149342, Austin, TX 78714-9342 or fax it to 855-887-7737, and keep dated proof of submission. Then keep records that reconcile to the form.
| Action | Why it prevents audits |
|---|---|
| File Form 5472 every year | Eliminates the non-filing flag — the #1 trigger |
| Attach the pro forma Form 1120 | A standalone Form 5472 is treated as incomplete |
| Use the current form revision | Old revisions can be deemed a failure to file |
| File by April 15 (or October 15 with Form 7004) | Late filing draws scrutiny and penalties |
| Mail to Austin or fax 855-887-7737, keep proof | Establishes the filing date if questioned |
| Keep records of every transaction | Satisfies the 6038A(a) record-keeping duty |

This is exactly what a filing service handles for you. form5472.tax prepares and files the complete package for a flat $299, removing the filing errors that draw the most 6038A scrutiny. We do not represent you in an audit — but a correct filing is the best way to avoid needing representation at all.
We help by filing accurate returns, not by representing you. form5472.tax prepares your Form 5472 and pro forma 1120 correctly, files the current revision on time, and helps with catch-up years — for a flat $299. For representation, you engage a licensed CPA, enrolled agent, or attorney.
Our role is preventive and well-defined. We prepare a complete, accurate Form 5472 and the required pro forma Form 1120, confirm the current revision, and file by mail or fax with proof of submission. If you have unfiled prior years, we can prepare those catch-up returns so the gaps are closed before the IRS notices them. Each of these steps directly reduces the chance an examination ever opens.
What we do not do is equally clear: form5472.tax does not represent clients before the IRS. We do not file Form 2848 as your representative, do not provide audit defense, and do not offer penalty-abatement or voluntary-disclosure representation. If you are already under examination, retain a licensed tax attorney, CPA, or enrolled agent.

The practical takeaway: use a filing service to stay compliant and keep audit risk low, and use a licensed representative if and when the IRS examines you. For a flat $299, we handle the filing that prevents most problems before they start.
Audit representation by a CPA, EA, or attorney is billed hourly and can run into thousands of dollars for a contested 6038A case. By contrast, filing a correct Form 5472 and pro forma 1120 up front costs a flat $299 at form5472.tax — far cheaper than fighting an audit later.
There is a large cost gap between prevention and cure. A licensed representative who defends a 6038A audit typically bills by the hour, and a contested case involving multiple unfiled years and stacked $25,000 penalties can cost far more than the penalties themselves once professional fees are added. Representation is essential when you need it — but it is expensive precisely because the stakes are high.
Filing correctly up front is dramatically cheaper. A flat $299 filing through form5472.tax removes the non-filing and incomplete-filing errors that cause most examinations. Even compared with other filing services — $547 at form5472.online, $1,999/yr at doola, and $999–$1,499/yr at Firstbase — the math favors getting the return right the first time.
| Path | Typical cost | When it applies |
|---|---|---|
| form5472.tax filing | $299 | Prevent most audits by filing correctly |
| form5472.online filing | $547 | Same filing, higher price |
| doola annual compliance | $1,999/yr | Bundled service |
| Audit representation (CPA/EA/attorney) | Hourly — often thousands | After the IRS opens an examination |

No. A non-resident owner does not need to travel to the United States. By signing Form 2848 from abroad, you appoint a US-licensed CPA, EA, or attorney to handle all correspondence, document requests, and conferences with the IRS on your behalf.
Foreign founders often fear that an IRS audit means flying to the United States. It does not. The entire examination can be conducted by correspondence and through your representative. Once you sign and file Form 2848 naming a licensed CPA, EA, or attorney, the IRS deals with that representative — sending notices, issuing information document requests, and holding any conference with them rather than you.
You sign Form 2848 from your home country and send it by mail or fax. Your representative then requests the audit file, produces the records you provide, and answers the agent's questions. For a disregarded entity there is no entity-level tax to litigate, so most 6038A matters resolve through documentation rather than in-person hearings.
The owner's main job is to provide clean records promptly — bank statements, agreements, and a transaction ledger — so the representative can reconcile them to the filed Form 5472. Good records and a valid Form 2848 keep the process entirely remote.
Response windows are short and strict. An Information Document Request (IDR) usually gives a few weeks; a 90-day notice for a 6038A failure starts the clock on extra $25,000 charges every 30 days. Missing a deadline can convert a manageable review into a default penalty assessment, so calendar every date the moment a letter arrives.
The single most damaging mistake in any IRS examination is letting a deadline pass. Each letter the IRS sends states a response date, and those dates are enforced. An Information Document Requesttypically allows a few weeks to produce records, and a reasonable extension can usually be negotiated by a representative if you ask before the deadline — not after. Silence, by contrast, is read as non-cooperation and pushes the agent toward an adverse finding.
For a 6038A non-filing, the structural deadline is the 90-day notice. Once the IRS notifies you of a failure to file Form 5472 and 90 days pass without the form, an additional $25,000penalty accrues for every 30-day period the failure continues, with no cap. Because the underlying information return has no statute of limitations under IRC 6501(c)(8), there is no point at which simply waiting makes the problem go away.
| Notice or request | Typical window | What missing it triggers |
|---|---|---|
| Information Document Request (IDR) | Roughly 2–4 weeks | Agent may proceed on incomplete record |
| 90-day failure-to-file notice (6038A) | 90 days | $25,000 every 30 days afterward, no cap |
| 30-day letter (proposed adjustment) | 30 days | Loss of the chance to respond before assessment |
| Notice of deficiency / final notice | Stated on the notice | Assessment becomes final; appeal rights narrow |

The practical rule is simple: the day a letter arrives, record every date it contains and contact a licensed CPA, EA, or attorney if the matter is an examination. For the mechanics of how accrual works after a notice, see our overview of the IRS late-filing penalty.
Yes. If a 6038A examination closes with a penalty you dispute, you can take it to the independent IRS Office of Appeals, and beyond that to the courts. Your licensed representative manages the appeal under the same Form 2848. A no-change closing or a reasonable-cause abatement can also end the matter without litigation.
An unfavorable audit result is not the final word. The IRS maintains an independent Office of Appeals whose job is to review a revenue agent's determination with fresh eyes and to settle disputes without litigation. To use it, your representative files a written protest setting out why the penalty should not stand — for example, that the return was complete, that records substantiate every transaction, or that reasonable cause excuses a late filing.
If Appeals does not resolve the matter, further avenues exist, including the US Tax Court and refund litigation after paying and filing Form 843. Each step is a representation matter handled by a licensed attorney, CPA, or enrolled agent acting under Form 2848 — not by a filing service. The strongest position at every stage is built from accurate prior filings and clean records.
| Stage | Who decides | Who acts for you |
|---|---|---|
| Examination | Revenue agent | Licensed CPA / EA / attorney |

The biggest triggers are a missing Form 5472 when an EIN exists, a standalone form without the pro forma 1120, an outdated revision, a late or unsigned filing, and figures that do not reconcile with the LLC's bank activity. Each is an avoidable filing error rather than a question of substance.
Because Form 5472 for a disregarded entity is an information return with no tax computation, the IRS does not audit it over disputed deductions. It audits it over structural defects — things a computer or a reviewer can spot at a glance. The most common is the absence of any Form 5472 for an LLC the IRS already knows is foreign-owned because an EIN was issued. Non-filing is, by a wide margin, the number-one trigger.
The next tier of red flags involves incomplete or malformed filings. A Form 5472 submitted without its pro forma Form 1120 cover is treated as substantially incomplete. An outdated form revision can be deemed a failure to file. A missing signature, a blank reportable-transactions section, or amounts that do not reconcile with the LLC's bank statements all invite a closer look. Each of these is a clerical defect, which is precisely why accurate preparation removes them.
| Red flag | Risk level | Fix |
|---|---|---|
| No Form 5472 filed despite an EIN | Highest | File now; consider catch-up filing |
| Filed without the pro forma 1120 | High | Always attach the 1120 cover |
| Outdated form revision used | High | Download the current revision |
| Reportable-transaction figures don't reconcile | Medium | Match Part IV–VI to bank records |
| Missing signature or blank required part | Medium | Review before mailing or faxing |
