Filed Form 5472 Late? Here's What to Do Now

You can file Form 5472 late for any missed tax year, back to when your LLC was formed. There is no IRS cut-off for filing a late return, but the longer a return stays unfiled, the more likely an IRS penalty notice arrives first and DIIRSP no longer applies to that year.

Practically:

• Within a few months of the deadline: file now under DIIRSP with a reasonable-cause statement.
• 1-2 years late: the same DIIRSP route, filing every missed year together.
• 3+ years late: still file every missed year, but the IRS may have already issued a notice you didn't see, so check your mail first.
• Already received a CP 215 notice: DIIRSP is no longer the right path for that year — you respond to the notice with an abatement request and appeal if denied.

The IRS does not publish DIIRSP outcome data, and its DIIRSP page says penalties may be assessed during processing without considering the attached reasonable-cause statement. A specific, documented statement is the strongest basis for responding if a penalty notice (such as CP 215) follows.

Within 6-18 months of the missed deadline, the IRS automated system issues a CP 215 notice to the LLC's US address of record, assessing the $25,000 penalty. Once that notice arrives, your options narrow:

• Pay the $25,000 (worst outcome for most owners).
• Request abatement, for example with Form 843 and a written reasonable-cause statement, as the notice directs. The IRS does not publish outcome data, and a specific, documented statement is the strongest basis for that response.
• Appeal through the IRS Office of Appeals (months of process).
• Ignore the notice — the worst path. Continuation penalties accrue at $25,000 per 30-day period after the 90-day grace window. Collection action can begin against the LLC's US-banked funds.

If the LLC's US address can't receive mail (e.g. a virtual mailbox that bounces IRS mail), you might not even see the CP 215 — but the penalty is still assessed and accruing.

1. Check whether you have received a CP 215 notice. The IRS has not yet assessed the penalty if you haven't received one.
2. Prepare the late return immediately. You need: cover letter, pro forma Form 1120, Form 5472, Part V supporting statement, AND a Reasonable Cause Statement at the front.
3. Write the Reasonable Cause Statement (or use our service to generate one tailored to the most common first-time-foreign-owner scenario).
4. File via DIIRSP — fax to +1-855-887-7737 (IRS Ogden PIN Unit), or mail certified to Internal Revenue Service, 1973 Rulon White Blvd, M/S 6112, Attn: PIN Unit, Ogden, UT 84201.
5. Set up an annual reminder so you file on time going forward (or sign up for an annual filing service).
6. Keep the fax transmission receipt as your timestamped transmission evidence.

File ALL missed years in one DIIRSP package. Don't space them out. The IRS treats a comprehensive catch-up filing more favorably than serial late filings — one consistent reasonable cause narrative covering the whole period is stronger than separate filings each blaming the same circumstances.

Our multi-year DIIRSP packages:

• 2-year catch-up: $248 Standard / $298 Express (fax included)
• 3-year catch-up: $347 Standard / $397 Express (fax included)

The wizard generates one cover letter, one Reasonable Cause Statement (covering all years), and a separate fully-completed Form 5472 + pro forma 1120 for each year. Everything assembled into one package, faxed once, with one timestamped receipt per year.

For 4+ missed years, run two back-to-back packages or message us and we'll coordinate.

The IRS looks for evidence you acted with "ordinary business care and prudence." Strong statements include:

• A clear timeline of when and how you became aware of the Form 5472 obligation.
• Specific personal circumstances — first-time foreign owner, language barrier, LLC was set up by an accelerator/Stripe Atlas package that didn't include annual compliance.
• If an adviser was involved, give the facts of that advice: what you asked, what information you gave them and what they told you. The IRS manual says relying on someone else to file is generally not reasonable cause, because the filing duty cannot be delegated (IRM 20.1.1.3.2.2.5), and reliance on a tax advisor's advice helps only in limited cases involving a technical or complicated substantive issue (IRM 20.1.1.3.3.4.3).
• Evidence of prompt corrective action upon learning of the failure.
• Explicit statement that no US tax is owed (this is true for almost all foreign-owned single-member LLCs).
• Confirmation that you've taken steps to ensure future compliance — annual reminder, calendar entry, filing service subscription.
• Concise — 1-2 pages.

Avoid vague excuses, contradictions with the form data, or aggressive language. Our auto-generated statement is tailored to the most common scenario and editable in the wizard if your facts are different.

DIIRSP is no longer the right path for that specific year — once the IRS has formally assessed a penalty, you're in the post-assessment abatement process. Steps:

1. Respond within 30 days of the notice (the notice will state the deadline).
2. File the late Form 5472 + pro forma 1120 separately if not already done.
3. Submit Form 843 (Claim for Refund and Request for Abatement) with a strong reasonable cause explanation tied to your specific facts.
4. If Form 843 is denied, appeal to the IRS Office of Appeals.
5. Consider engaging a tax attorney or enrolled agent — post-assessment appeals are more complex than DIIRSP and a professional adds value.

We don't currently handle CP 215 abatement appeals — only preventative DIIRSP filings. If you have a CP 215 notice already, talk to a US tax professional who handles international information return penalties.

For any other unfiled years where you haven't been contacted yet, DIIRSP is still available — file those concurrently while you handle the CP 215 for the assessed year.

After a late Form 5472 filing, the current instructions do not describe a routine acceptance acknowledgment for this faxed package. Keep the exact submitted package, destination, timestamp, page count, provider receipt and IRS correspondence because a transmission record does not guarantee penalty removal.

Do not send a duplicate solely because you have heard nothing. If a notice arrives, follow its instructions and response deadline. See receipt confirmation and next steps.

Real-world late filings range from a just-missed return to multi-year DIIRSP catch-up or a CP 215 appeal problem. Carlos files one month after the 2024 return was due, Mei catches up several years together, and Ahmed faces $100,000+ continuation penalties by 2026.

Scenario B — three-year catch-up: Mei has had a Delaware LLC since 2022, never filed. Discovers obligation in 2026. Files 2022, 2023, 2024, and 2025 together in one DIIRSP package. (Our wizard supports 3 years, so 2022 would run as a separate filing.) No outcome is guaranteed: penalties may still be assessed during processing, and her documented statement is then the basis for responding.

Scenario C — ignored a CP 215: Ahmed received a CP 215 in July 2024 for tax year 2022. By 2026, continuation penalties have stacked to $100,000+. Needs both to file the actual return AND to engage a tax professional to handle the assessed penalty appeal. Much more expensive and stressful than scenarios A and B.

The takeaway: act fast. Even multi-year catch-up is vastly cheaper than waiting for an IRS notice and then delaying.

Yes, the IRS can notice if you do not file, even though it may not catch every non-filer in year 1. EIN cross-references, payment processor reports, bank account activity and CP 215 routines all make silence a risky basis for ignoring Form 5472.

How the IRS finds you:

• EIN database cross-reference — every EIN issued to a foreign-owned entity is flagged for expected annual returns.
• Stripe Atlas / Mercury / formation services occasionally share aggregate data with the IRS for compliance purposes.
• Bank account openings (foreign-owned US LLC accounts trigger reporting under various AML / KYC frameworks).
• Customer 1099-K reports — if your LLC received payment processing volume from US-based processors (Stripe, PayPal, Square), the IRS sees the LLC's EIN reported on those forms.

The IRS doesn't usually catch every non-filer in year 1, but the longer you wait the more likely they catch up. CP 215 notices are routine for foreign-owned LLCs that miss Form 5472. Don't bet on silence.

Our DIIRSP-aware filer handles the entire late-filing package. The wizard asks 12 questions about your LLC, owner, and year-end totals for each missed year. We generate everything — cover letter, pro forma Form 1120, Form 5472, Part V supporting statement, AND the Reasonable Cause Statement.
