Missed Form 5472: Catching Up and Penalty Relief

I just found out I should have filed Form 5472. What do I do first?

First, confirm which years required Form 5472 and whether the entity filed the accompanying Form 1120. Work through every missing year. The IRS recommends filing delinquent returns before requesting reasonable cause relief. If a notice is pending, respond by its deadline while finishing the filings. IRS: Form 5472 instructions; IRS: International penalties manual.

Gather the entity's formation and ownership dates, employer identification number, copies of returns and extensions, bank statements, books, owner contributions and withdrawals, other related-party transactions, and every IRS letter. A zero-revenue year can still require a form if the owner funded the LLC or paid its expenses. For the full transaction test, see foreign-owned single-member LLC filing or foreign-owned C corporation filing.

If you suspect the omission was deliberate or involved hidden income, review the voluntary disclosure question below before choosing a catch-up route.

Which past years do I have to file, and how far back can the IRS go?

Check each year separately; there is no blanket rule to file only the most recent three years. Check who owned the entity and whether the owner was a foreign person for US tax purposes, then check transactions and filing exceptions. Foreign ownership at any time during a corporation's tax year can trigger the rule, even if the owner later becomes a US tax resident. An effective section 6013(g) or (h) joint-return election removes an individual from Form 5472's definition of a foreign person. Both spouses sign the election statement with their first joint return; they may instead elect on an amended joint return within the later of three years after filing or two years after payment. IRS: Form 5472 instructions; IRS: Nonresident spouse.

The special rule for a foreign-owned US disregarded LLC begins with tax years starting on or after January 1, 2017, and ending on or after December 13, 2017; a corporation may have earlier required years. One corporation exception applies when the required Form 5471 and Schedule M reported all transactions with a related foreign corporation, but it does not apply to a foreign-owned US disregarded LLC. See the LLC rules or corporation rules for the full test. IRS: Form 5472 instructions.

An unfiled or materially incomplete Form 5472 can keep the assessment period open. IRS guidance says the period for assessing an international information return penalty generally runs three years after a complete return is filed, including when it is filed late. Missing required information can also extend the assessment period for the related income tax return; reasonable cause may limit that extension for unrelated tax items. Do not assume an old year is closed without reviewing its filings and facts. IRS: International penalties manual.

How do I file a late Form 5472 for an LLC or corporation?

Attach each late Form 5472 to the return for that same tax year. The route depends on what was already filed; a stand-alone Form 5472 is not the normal catch-up filing. IRS: Form 5472 instructions; IRS: Delinquent return procedures.

The IRS delinquent information return procedure applies only if the entity has not been contacted about the missing return and is not under civil examination or criminal investigation. If contacted, follow the notice and coordinate the correction with the IRS contact. If an LLC already filed its pro forma Form 1120 but omitted Form 5472, the general procedure calls for an amended return; confirm the amended pro forma package and delivery route because the LLC has special Form 5472 instructions. It cannot file Form 5472 electronically. Keep a copy and delivery proof. IRS: Delinquent return procedures; IRS: Form 5472 instructions; IRS: Corporate return corrections; IRS: Form 1120-X instructions.

Should I attach a reasonable cause statement, and what should it say?

Attach a separate, signed statement for each late year if the entity has facts supporting reasonable cause. State what prevented timely filing, when the entity learned of the requirement, what it did to comply, and the dates it corrected the failure. Attach records that support the timeline; do not make claims you cannot document. IRS: Delinquent return procedures; eCFR: 26 CFR 1.6038A-4(b).

The regulation requires an affirmative account of all facts relied on and a declaration under penalties of perjury. An IRS reviewer decides whether the entity acted in good faith and had reasonable cause. An attached statement may not be considered before a penalty is assessed, so be ready to send it again in response to an IRS notice. eCFR: 26 CFR 1.6038A-4(b); IRS: Delinquent return procedures.

Will the IRS still charge a penalty if I file on my own?

Yes, the IRS may assess a penalty even when the entity files voluntarily with a reasonable cause statement. For a tax year beginning after the older penalty regime, the initial Form 5472 penalty is $25,000 for each related party and year with a failure. A substantially incomplete form counts as a failure to file. IRS: Form 5472 instructions; eCFR: 26 CFR 1.6038A-4(a).

A continuation charge applies only if the failure persists beyond the notice period. If both a filing and a recordkeeping failure continue for the same related party, the IRS may assess separate continuation penalties. IRS: International penalties manual. Having no income tax due does not remove the Form 5472 filing duty. IRS: Form 5472 instructions.

Does first-time abatement apply to a Form 5472 penalty?

First-time abatement does not apply directly to Form 5472. There is a narrow IRS processing exception when a Form 5472 penalty was assessed automatically because it was attached to a late Form 1120. IRS: International penalties manual.

The reference and the Form 1120 filing history matter; do not assume a CP215 qualifies from its title alone. Reasonable cause remains a separate path even if the narrow first-time rule does not fit. For the Form 1120 penalty itself, see late filing and payment penalties. IRS: International penalties manual.

Does ignorance or reliance on a preparer count as reasonable cause?

Specific tax advice may support reasonable cause when relying on it was reasonable; hiring a preparer or formation service to handle filing generally does not. Record the question asked, ownership and transaction facts supplied, advice received, and why the entity relied on it. If someone simply failed to file, document the entity's own efforts to meet the deadline. Keep the engagement letter and follow-up records. eCFR: 26 CFR 1.6038A-4(b); IRS: Penalty relief manual.

The IRS must apply the reasonable cause exception liberally to a corporation with gross receipts of $20,000,000 or less for the tax year if it lacked knowledge of the requirement, had limited US presence and contact, and promptly and fully complied with IRS requests for the form and records. This is a relief standard, not an exemption from filing or an automatic waiver. IRS counsel says the receipts measure is overall receipts, not only US receipts, and all conditions must be established. eCFR: 26 CFR 1.6038A-4(b)(2); IRS: Chief Counsel Advice 202617012.

I got a CP215 notice. How do I respond or appeal?

A CP215 reports an assessed civil penalty; it does not establish whether Form 5472 is still missing. Match its entity, tax period, reason, amount, and deadline to the filed return and delivery proof. If the form is missing, file it promptly. Call the number on the notice or send an abatement request with a signed reasonable cause statement and records. Keep copies and proof of delivery. IRS: Understanding your CP215 notice; IRS: Penalty relief.

If a complete Form 5472 was filed on time, send a copy and proof of timely filing. If it was late or incomplete, explain the facts and request available relief. If the IRS cannot grant relief by phone, it says you may request relief in writing with Form 843. If relief is denied, the denial letter gives the appeal deadline and instructions; an IRS appeal is generally requested within 30 days of that letter, but follow the specific letter. Payment by the CP215 due date can avoid interest on that assessed balance, but paying does not file a missing form. IRS: CP215; eCFR: 26 CFR 1.6038A-4(a); IRS: Penalty relief; IRS: Penalty appeal.

How do I stop the penalty from growing after an IRS notice?

Supply a complete Form 5472 and any requested records promptly. Find the IRS letter that identified the specific filing or record failure and its mailing date. A 90-day cure window starts when the IRS mails that failure notice, not on the CP215 payment due date. If reasonable cause continued after notice, the regulation treats the window as beginning no earlier than the last day reasonable cause existed. A failure continuing beyond that window can draw another charge for each 30-day period or part, without a stated maximum. The IRS manual says there is no separate reasonable cause exception once a continuation penalty applies. eCFR: 26 CFR 1.6038A-4(b), (d); IRS: International penalties manual; IRS: CP215.

Paying an assessed CP215 balance can stop interest on that balance, but it does not cure an unfiled or incomplete Form 5472. If an IRS letter requests records as well as the form, address both requests and preserve delivery evidence. IRS: CP215; eCFR: 26 CFR 1.6038A-4.

Can I close the LLC to make missed years go away?

No. Closing the LLC does not erase earlier federal filing obligations or assessed penalties. The IRS says it cannot close a business account until necessary returns are filed and taxes paid. Check the final year for reportable transactions and retain the records needed to answer IRS questions. State dissolution and final state filings depend on where the LLC was formed or registered. IRS: Closing a business.

When is the IRS voluntary disclosure practice the route instead?

Consider the IRS Criminal Investigation Voluntary Disclosure Practice before filing catch-up returns if the noncompliance was willful and created criminal exposure. It requires a truthful, timely, complete disclosure and does not guarantee immunity. Timing matters: a disclosure may be too late after an examination or investigation begins, or after the IRS receives information about the noncompliance. IRS: Voluntary Disclosure Practice.

An inadvertent missed Form 5472 is usually addressed through original or amended filings and a reasonable cause request, subject to the IRS procedure's eligibility limits. Where conduct may have been deliberate, get cross-border tax help before choosing a procedure. IRS: Voluntary Disclosure Practice; IRS: Delinquent return procedures.

Example

Illustrative US-dollar amounts: a foreign owner puts US$20,000 into a single-member US LLC in its first year and another US$5,000 into it the next year. The LLC has no sales and files no Forms 5472. If each contribution is reportable and the owner is the only related party, the two missed years can produce US$25,000 of initial penalty each, or US$50,000 before any relief. The owner gathers both years' bank records and files a separate pro forma Form 1120 and Form 5472 for each year, describing that year's contribution on the Form 5472 Part V attachment. The owner sends a fact-supported reasonable cause statement for each year. The IRS may still assess the penalties and consider the statements later. IRS: Form 5472.

Different for you?

The next step changes with the entity, missing returns, and where you live:

• You need the annual LLC filing rules or transaction list: see foreign-owned single-member LLC filing.
• A US C corporation missed its whole income tax return: see catching up on unfiled business returns.
• You need to know whether the owner owed US income tax: see when foreign owners owe US tax.
• You live in the US and missed personal foreign reporting: see catching up on missed foreign reporting.
• You live in Canada and own the LLC: check possible Canadian filing in Canadian owner of a US LLC.
• The LLC's records cannot yet show owner transactions: see catching up on overdue books.
• You received a penalty notice, missed several years, or may have filed deliberately incomplete returns: bring the notices, prior filings, ownership history, and bank records to cross-border tax.
