Form 5471 guide for US taxpayers with foreign corporations

IRS Form 5471 is an information return that US persons file to report their interests in certain foreign corporations. It is attached to your income tax return – not filed separately – and is required even if the foreign corporation had no income and you owe no US tax.

The penalty for not filing is $10,000 per foreign corporation, per year. If you ignore an IRS notice, additional penalties can push the total to $60,000 per form.

Your Form 5471 is a core part of your US tax return if you own a foreign corporation. Three things to know:

• Who files: US citizens, green card holders, and residents who are shareholders, officers, or directors of certain foreign corporations – based on five filer categories.
• Which category applies: Your filer category depends on your ownership percentage, whether the corporation is a CFC, and whether you acquired or disposed of stock during the year.
• What the penalty exposure is: $10,000 initial penalty per form, plus continuation penalties up to $50,000, plus a potential reduction in your foreign tax credits – and an open-ended statute of limitations until the form is filed.

Based on a TFX client scenario: A US citizen started a software company in Ireland and owned 100% of the shares. In the first year she crossed the ownership threshold, she became a Category 4 and Category 5 filer and attached Form 5471 to her Form 1040.

What is Form 5471?

Form 5471, Information Return of US Persons With Respect to Certain Foreign Corporations, is an IRS information return – not a tax return. It reports your ownership, financial activities, and transactions involving a foreign corporation. No tax is calculated on the form itself.

You need to know two things about Form 5471 before anything else:

What it is:

• An information return filed with your income tax return (Form 1040 for individuals, Form 1120 for corporations)
• Required under IRC sections 6038 and 6046 for US persons who are shareholders, officers, or directors of certain foreign corporations
• Due on the same date as the income tax return it attaches to, including extensions

What it is not:

• Not a standalone filing – it must be attached to your return
• Not a tax return – it does not calculate any tax liability
• Not optional when you meet a filing category – the $10,000 penalty applies regardless of whether the corporation earned income

A US person includes US citizens, green card holders, domestic corporations, domestic partnerships, and certain trusts and estates. If you hold an ownership interest in a foreign corporation and meet one of the five filer categories described below, you must file.

What’s new for the 2025–2026 filing season

The IRS released a December 2025 revision of Form 5471 with several updates that apply to your tax year 2025 return, filed in 2026.

New for this filing season (December 2025 revision):

• One-month deferral repealed. Under OBBBA section 70352, a specified foreign corporation tax year beginning after November 30, 2025, can no longer start one month before the majority US shareholder’s tax year. This affects the CFC’s annual accounting period and may shift which schedules apply.
• Pro rata share transition rule. OBBBA section 70354(c)(2) and IRS Notice 2025-75 provide transition guidance. New Schedule G question 22b and Worksheet A line 46 support this rule.
• Schedule G, question 3b. New question about qualified business units with a different functional currency.
• Schedule G, line 21. New question about section 304 transactions affecting E&P or previously taxed earnings and profits (PTEP).
• Schedule E, column (j). Updated instructions require a statement for taxes allocated under the one-month deferral repeal.

Carried over from the December 2024 revision:

• Schedule H-1 for reporting a CFC’s adjusted net income or loss for corporate alternative minimum tax (CAMT) purposes. This schedule is required only when the US shareholder is a CAMT “applicable corporation” – individual owners generally do not file it.
• Lines 20a and 20b on page 6 of the form for reporting any Top-up Tax paid or accrued.
• Schedule Q – removed shading from line 4, column (xv), creating a new entry space for loss allocations in subpart F excluded groups.
• Schedule I, Worksheet A – updated to reflect computational rules more clearly under Reg. section 1.954-1.

What did not change: The five filer categories, the penalty structure, and the core schedules – A through R – remain the same as prior years.

Filing deadline

Form 5471 is due on the same date as the income tax return it attaches to. For most individual filers reporting tax year 2025, the deadlines are:

 

Unlike a standalone return, tax Form 5471 rides with your income tax filing – it is never submitted on its own. If you file a partnership return on Form 1065 or a corporate return on Form 1120, the Form 5471 deadline follows that entity’s due date.

An extension to file is not an extension to pay. Any taxes owed are due April 15, 2026, and interest accrues from that date regardless of which extension applies.

Non-calendar-year filers and entities may have different due dates based on their fiscal year-end. Check the Form 5471 instructions for the specific rule that applies to your filing.

First-year filing rules

The first year you become subject to Form 5471 depends on which event triggers your filer category.

Common first-year triggers:

• You acquire 10% or more of a foreign corporation’s stock – by vote or value. This triggers Category 3 and, if the corporation is a CFC, Category 5.
• You incorporate a foreign company. If you own more than 50%, you are a Category 4 filer from the corporation’s first tax year.
• You become a US person while holding 10% or more. Obtaining a green card or meeting the substantial presence test while owning foreign corporate stock can trigger Category 3 filing.
• You are appointed as an officer or director of a foreign corporation in which a US person acquires 10% or more stock. This triggers Category 2.

Example – timeline for a new shareholder:

1. Year 1: A US citizen invests $50,000 for a 15% stake in a UK limited company. Total US ownership is 30%, so the company is not a CFC. She files Form 5471 as a Category 3 filer for the acquisition year.
2. Year 2: Another US investor buys 25% of the company. Combined US ownership exceeds 50%. The company becomes a CFC. She now files as a Category 5 filer.
3. Year 3 and beyond: She continues filing as Category 5 each year she remains a 10%+ shareholder of a CFC.

The filing obligation starts in the tax year the triggering event occurs. It does not retroactively cover prior years – but once triggered, it generally continues as long as you meet a filer category.

Who needs to file Form 5471?

You need to file Form 5471 if you are a US person who falls into one of five filer categories. Each category targets a different aspect of your involvement with a foreign corporation.

The five filer categories determine which schedules you complete, not just whether you file. A single filer can fall into more than one category and must complete all applicable schedules.

Quick self-check – you likely file Form 5471 if:

• You own 10% or more of a foreign corporation’s stock – by vote or value
• You are an officer or director of a foreign corporation in which a US person acquired 10%+ stock
• You had control – more than 50% – of a foreign corporation at any time during the year
• You are a US shareholder of a controlled foreign corporation

You likely do not file if:

• You own less than 10% and have no officer or director role
• You hold stock only through a US intermediary that files its own Form 5471
• Your interest is in a foreign partnership – reported on Form 8865 – or a foreign disregarded entity, reported on Form 8858

 

Category 1

Category 1 applies to US shareholders of section 965 specified foreign corporations (SFCs). This is a legacy category tied to the 2017 transition tax.

When it applies: You owned stock on the last day the corporation was a section 965 SFC, and the corporation still has section 965 E&P reportable on Schedule J, or you still have section 965 PTEP reportable on Schedule P.

Subcategories:

• 1a: General – any Category 1 filer that is not 1b or 1c
• 1b: Unrelated section 958(a) US shareholder of a foreign-controlled SFC
• 1c: Related constructive US shareholder

How Category 1 differs from Category 5: Category 1 is limited to section 965 SFCs and their accumulated transition-tax earnings. Category 5 covers all CFCs and applies to ongoing Subpart F and GILTI reporting. Most new expat filers fall under Category 4 and 5, not Category 1.

Filing under Category 1 continues only while section 965 E&P or PTEP remains reportable.

Category 2

Category 2 applies to US citizens or residents who are officers or directors of a foreign corporation in which a US person acquires stock meeting the 10% threshold.

What triggers Category 2:

• A US person acquires stock that, combined with stock already held, reaches 10% or more of total vote or value
• A US person acquires 10% or more in a single transaction

The trigger is the acquisition event, not an ongoing ownership interest. Category 2 does not apply to stock dispositions.

Based on a TFX client scenario: A US citizen serving as a director of a Canadian corporation learned that another US person had bought 12% of the company’s shares in 2025. She filed Form 5471 as a Category 2 filer, attaching Schedule O to report the acquisition.

Documents to keep:

• Board appointment records
• Stock purchase agreement or share registry showing the acquisition
• Ownership chart before and after the transaction

Category 3

Category 3 applies to US persons whose ownership in a foreign corporation crosses the 10% threshold – either up or down – during the tax year.

Three types of triggering events:

• Acquisition: You acquire stock that brings your total to 10% or more of the corporation’s vote or value.
• Disposition: You dispose of stock and drop below 10%.
• Status change: You become a US person – for example, by obtaining a green card – while already holding 10% or more.

The 10% threshold is measured by total combined voting power or total value, using direct, indirect, and constructive ownership under IRC section 958.

Based on a TFX client scenario: A US person acquired a 12% stake in a German GmbH in March 2025. She filed Form 5471 as a Category 3 filer, reporting the acquisition on Schedule O. When she later sold half her stake and dropped to 6%, she filed again in the disposition year.

Filers in Category 3 may also need to attach a supporting statement to the return if the ownership change involves constructive ownership.

Category 4

Category 4 applies to US persons who had control of a foreign corporation at any time during the tax year. Control means owning more than 50% of the total combined voting power or more than 50% of the total value.

Key details:

• Control is tested on any day during the corporation’s annual accounting period – not just year-end
• A chain-of-control rule applies: if you control Corporation A, and Corporation A owns more than 50% of Corporation B, you are treated as controlling Corporation B
• Attribution rules under IRC section 318, as modified, apply to determine ownership

Based on a TFX client scenario: A US person owned 55% of a Hong Kong company from January through March 2025, then sold down to 40%. She was still a Category 4 filer for 2025 because she had control at some point during the year.

Records to keep:

• Stock certificates or share registry
• Ownership chart showing direct, indirect, and constructive ownership
• Documentation of any ownership changes during the year

If you meet both Category 4 and Category 5a, you check only Category 4 on the form. The schedule requirements of both categories apply.

Category 5

Category 5 applies to US shareholders of controlled foreign corporations. For tax year 2025, you must have owned the stock on the last day in the CFC’s tax year that the corporation was a CFC.

Decision tree:

1. Is the foreign corporation a CFC – do US shareholders collectively own more than 50% of vote or value? → If no, Category 5 does not apply.
2. Are you a US shareholder – do you own 10% or more of vote or value, counting direct, indirect, and constructive ownership? → If no, Category 5 does not apply.
3. Did you own the stock on the last day the corporation was a CFC during its tax year? → If yes, you are a Category 5 filer.

Subcategories:

• 5a: General – the most common subcategory for individual expat owners of CFCs
• 5b: Unrelated section 958(a) US shareholder of a foreign-controlled CFC
• 5c: Related constructive US shareholder of a foreign-controlled CFC

How Category 5 differs from Category 1: Category 1 is limited to section 965 SFCs and transition-tax earnings. Category 5 covers all CFCs regardless of section 965 status.

How Category 5 differs from Category 3: Category 3 is triggered by an ownership change event. Category 5 is triggered by ongoing CFC ownership.

 

For a deeper look at CFC ownership and attribution, see our TFX guide to controlled foreign corporations.

Exceptions from filing Form 5471

The IRS allows exceptions from filing in specific circumstances. These are narrow and depend on your filer category, ownership facts, and entity classification.

Exceptions are category-specific. Qualifying for one exception does not exempt you from filing under a different category.

 

Caution: Exceptions are narrow and often depend on specific ownership facts and entity classification. When in doubt, file. The $10,000 penalty for not filing when required is far greater than the cost of filing when not required.

See our TFX guide to US tax forms for expats for a broader look at the forms most US expats file alongside Form 5471.

Form 5471 filing checklist

Use this checklist to verify your filing is complete before submission. Filers with multiple foreign corporations file separate 5471s for each corporation.

• Filer category identified – Categories 1–5, including subcategories
• Ownership percentage calculated – direct, indirect, and constructive
• CFC status determined – US shareholders collectively own more than 50% of vote or value
• Foreign corporation’s EIN obtained, or applied for on Form SS-4
• Financial statements collected – balance sheet, income statement, in the CFC’s functional currency
• All required schedules completed for your filer category
• Ownership changes during the year reported on Schedule O (Categories 2 and 3)
• Related-party transactions reported on Schedule M (Category 4)
• Subpart F income and GILTI calculated and reported on Schedules I and I-1 (Category 4 and 5; Category 5c files Schedule I-1 only)
• Previously taxed earnings tracked on Schedule P (Categories 1a, 1b, 4, 5a, and 5b)
• Supporting statements attached (if required by your category or an exception)
• Form 5471 attached to your income tax return
• Copies retained for at least six years

Form 5471 schedules

The schedules you file depend on your filer category. The table below maps each schedule to its purpose and the categories that commonly require it.

 

Three Form 5471 schedules come up often in CFC filings: Schedule I reports Subpart F income and section 956 inclusions, Schedule J tracks accumulated earnings and profits, and Schedule M captures related-party transactions.

Which ones apply depends on your category. Schedule I applies to Categories 4, 5a, and 5b, Schedule J applies to Categories 1a, 4, and 5a, and Schedule M applies only to Category 4. A Category 5a filer generally completes Schedules I and J but not Schedule M.

For a detailed look at Schedule J, see our TFX guide to Form 5471 Schedule J.

The 5471 schedules you complete determine the level of detail the IRS receives about your foreign corporation. Filing with missing schedules is treated the same as not filing – the $10,000 penalty applies.

What is a controlled foreign corporation (CFC)?

A controlled foreign corporation is a foreign corporation in which US shareholders collectively own more than 50% of the total combined voting power or total value of stock. A US shareholder, for this purpose, is any US person who owns 10% or more of the corporation’s stock by vote or value.

CFC status matters for Form 5471 because it determines whether you must report the corporation’s income on your US return – even if no dividends are paid.

CFC test – two conditions:

• The corporation is organized outside the United States
• US shareholders (those at 10%+) together own more than 50% of vote or value, measured on any day during the CFC’s tax year

Based on a TFX client scenario: Three US persons each owned 20% of a foreign corporation. Combined US ownership was 60%, exceeding 50%, so the corporation was a CFC. Each 20% owner filed the required CFC Form 5471 schedules with their return.

Counterexample – not a CFC. A US person owns 8% of a foreign corporation. Even if total US ownership exceeds 50%, the 8% owner is not a US shareholder (below 10%) and does not count toward the 50% CFC threshold.

Ownership is measured using direct, indirect, and constructive ownership under IRC section 958. Family attribution can push you over the 10% threshold – stock owned by your spouse, children, grandchildren, or parents may be counted as yours.

A controlled foreign corporation reported on Form 5471 is subject to Subpart F, GILTI, and section 956 – the three main regimes that can tax CFC income to US shareholders before any distribution is made.

 

Subpart F income and GILTI: what you need to know

CFC shareholders must report two categories of income on their US returns each year – regardless of whether the CFC distributes anything. The rules differ in what they target, how they are calculated, and which credits apply.

Subpart F income

Subpart F targets specific categories of income that are easy to shift across borders or park in low-tax jurisdictions. It is broader than passive income alone.

Main Subpart F categories:

• Foreign personal holding company income – dividends, interest, rents, royalties, and certain capital gains
• Foreign base company sales income – income from buying or selling property involving a related party, where the property is manufactured and sold outside the CFC’s country of incorporation
• Foreign base company services income – income from services performed for a related party outside the CFC’s country
• Insurance income – income from insuring risks outside the CFC’s country
• International boycott and illegal payment income

Subpart F income is taxed to the US shareholder in the year the CFC earns it. No distribution is required. The income is reported on Form 5471, Schedule I.

For a detailed breakdown, see our TFX guide to Subpart F income.

GILTI (global intangible low-taxed income)

GILTI applies to active CFC income that exceeds a routine return on the CFC’s tangible business assets. It was added by the Tax Cuts and Jobs Act in 2017 and is reported on Form 8992 and Form 5471, Schedule I-1.

GILTI formula (tax year 2025):

GILTI inclusion = your share of CFC tested income – (10% × your share of qualified business asset investment, reduced by specified interest expense)

Individual shareholders pay tax on GILTI at ordinary income rates – up to 37% – unless they make a section 962 election to be taxed at corporate rates (effective rate of 10.5% for tax year 2025, with a second layer of tax when earnings are later distributed).

The GILTI high-tax exception can exclude CFC income from GILTI if the effective foreign tax rate exceeds 18.9% (90% of the 21% US corporate rate). It is an annual election.

See our TFX guide to the GILTI high-tax exception for details.

Subpart F vs GILTI comparison:

 

For tax year 2026 and beyond: GILTI is renamed NCTI (net CFC tested income) under the OBBBA. The section 250 deduction drops from 50% to 40%, the foreign tax credit increases from 80% to 90%, and the 10% QBAI deemed return is eliminated. These changes apply to CFC tax years beginning after December 31, 2025.

What’s the difference between Form 5471 and Form 5472?

Form 5471 and 5472 both report transactions involving foreign entities, but they apply to different taxpayers and serve different purposes.

 

Common confusion: Taxpayers often mix up the two forms because both involve foreign ownership. The distinction is the direction of the relationship. Form 5471 looks outward – a US person reporting on a foreign corporation they hold. Form 5472 looks inward – a foreign-owned US entity reporting on transactions with its foreign owner.

In some cases, both forms may be relevant. A US person who owns a foreign corporation (Form 5471) and also owns a US LLC with foreign co-owners (Form 5472) could need to file both.

For a full breakdown, see our TFX guide to Form 5472.

Form 5471 filing requirements

Form 5471 filing requirements apply whenever a US person meets one of the five filer categories – regardless of whether the foreign corporation earned income or the filer owes US tax. The form is an information return, and the filing obligation is separate from any income tax liability.

Three parts of the Form 5471 requirements:

• Who is covered: US citizens, green card holders, resident aliens, domestic corporations, domestic partnerships, and certain trusts and estates – anyone who qualifies as a US person under IRC section 7701
• What facts trigger filing: The five filer categories described above – each tied to specific ownership thresholds, control tests, or officer/director status
• Which records are needed: Financial statements of the foreign corporation (in its functional currency), ownership charts, transaction records, and supporting statements where required

Form 5471 reporting requirements differ from filing requirements. Filing is the obligation to submit the form. Reporting is what goes on it – the specific financial and ownership data the IRS requires for each schedule.

An incomplete form that omits required schedules is treated the same as a missing form for penalty purposes. You may see the form referred to as F5471 in IRS correspondence or practitioner shorthand – it is the same filing.

What are the penalties for not filing Form 5471?

The IRS imposes a $10,000 penalty for each Form 5471 that is late, incomplete, or missing – per foreign corporation, per annual accounting period (IRC section 6038(b)). This applies even if the foreign corporation had no income.

Penalty breakdown:

• Initial penalty: $10,000 per foreign corporation, per year
• Continuation penalty: After 90 days from an IRS notice of failure, an additional $10,000 for each 30-day period (or fraction) the form remains unfiled – capped at $50,000 additional
• Maximum per form, per year: $60,000 – $10,000 initial plus $50,000 continuation
• Foreign tax credit reduction: 10% reduction in available foreign tax credits, plus 5% for each additional 3-month period of non-compliance – capped at the greater of $10,000 or the foreign corporation’s income for the year
• Accuracy-related penalty: 20% of any tax understatement caused by errors on the form. This increases to 40% under IRC section 6662(j) when the understatement is tied to an undisclosed foreign financial asset.
• Open statute of limitations: Under IRC section 6501(c)(8), the IRS can assess additional tax on your entire return until three years after the missing Form 5471 is filed. If the form is never filed, this window never closes. With reasonable cause, the extended period is limited to items related to the foreign corporation.

Based on a TFX client scenario: A US taxpayer with interests in two foreign corporations had missed Form 5471 for three years. Initial penalty exposure at the time TFX took the case: 2 × 3 × $10,000 = $60,000 – before continuation penalties.

Penalties may be reduced or eliminated if you can demonstrate reasonable cause – showing that unexpected circumstances prevented timely filing and that you made genuine efforts to comply. The defense requires a written statement under penalties of perjury with supporting documentation.

For a detailed look at penalty amounts, abatement options, and the Farhy case, see our TFX guide to Form 5471 penalties.

Unfiled Forms 5471 may qualify for penalty relief through the Streamlined Filing Procedure.

What if Form 5471 was missed in prior years?

If you missed Form 5471 in prior years, the issue is fixable – but the approach depends on how many years you missed, whether you live in the US or abroad, and whether your non-compliance was willful.

One year missed:

File the delinquent Form 5471 with an amended return – Form 1040-X – for the year the form was due. Attach a reasonable cause statement explaining why the filing was late.

Filing before the IRS contacts you avoids the continuation penalty and gives the strongest position for penalty abatement.

Multiple years missed – living abroad:

If you lived outside the US for at least 330 full days in one of the last three tax years and your failure was non-willful, the Streamlined Foreign Offshore Procedures may apply.

SFOP requires three years of delinquent or amended returns and six years of FBARs. No offshore penalty is assessed under the foreign track.

Multiple years missed – living in the US:

SDOP applies a 5% miscellaneous offshore penalty on the highest aggregate year-end balance of unreported foreign financial assets.

Eligible taxpayers document their non-willfulness on Form 14654, the domestic offshore certification.

Decision framework:

 

Do not self-classify as non-willful without professional advice. An incorrect certification under the Streamlined procedures constitutes perjury.

See our TFX guide to what to do if you’ve never filed for a broader look at catching up.

Tips to stay compliant with Form 5471

Annual compliance checklist:

• Track ownership changes in real time. Any acquisition or disposition of stock during the year can trigger a new filer category or end an existing one. Document every change as it happens – not at year-end.
• Maintain corporate records in the CFC’s functional currency. You will need balance sheets, income statements, and transaction records translated into US dollars for the schedules.
• Note filing deadlines early. Mark your tax return due date – and any extension deadline – at the start of the year. The June 15 automatic extension for expats does not extend the time to pay.
• Review CFC-related income annually. Check whether the CFC has Subpart F income, GILTI, or section 956 investments that create a US income inclusion even without a distribution.
• Get professional review before year-end. A mid-year check with a CPA who handles foreign company tax reporting can catch issues – such as ownership attribution or missed categories – before filing season starts.
• Keep records for at least six years. The IRS can examine your return years after filing if a Form 5471 was incomplete or the statute of limitations was extended.
