Form 5471 Schedule G: other information and Schedule G-1 explained (2026)

Form 5471 Schedule G: other information and Schedule G-1 explained (2026)

Schedule G is the "other information" section of Form 5471. It asks a series of yes/no questions about the foreign corporation's activities, ownership structure, and related-party transactions.

Your answers determine which additional forms and schedules the IRS expects to see attached to your return.

A wrong or incomplete answer can mean a missing related form – and every missing form under IRC 6038 carries a $10,000 penalty per foreign corporation per year (2025).

This guide walks through the key questions, explains when Schedule G-1 applies, and covers the penalties for getting it wrong.

Who must complete Schedule G

Schedule G is required for filers in Categories 1c, 3, 4, 5a, and 5c. If you fall into more than one category, you still complete only one Schedule G – but you must answer every question that applies to any of your filing categories.

Most US expats who own or control a foreign corporation file as either a Category 4 or Category 5 filer.

Category 4 covers US persons who had "control" of the foreign corporation at any point during the year – meaning they owned more than 50% of the total voting power or total value of shares.

Category 5 covers US shareholders who own 10% or more of a controlled foreign corporation.

Category 3 filers also complete Schedule G. This category covers US persons who acquire stock that brings their total ownership to 10% or more, or whose newly acquired stock alone reaches that threshold.

It also covers anyone who becomes a US person while already owning 10% or more, disposes of enough stock to fall below 10%, or is treated as a US shareholder under Section 953(c).

Category 1c filers report on specified foreign corporations under Section 965.

Form 5471 Schedule G at a glance: what the questions cover

Schedule G contains 21 numbered questions. Most are yes/no questions about the foreign corporation's relationships, structures, and arrangements that trigger additional reporting, and several also ask for dollar amounts, such as base erosion payments or disallowed interest deductions. The foreign corporation's income statement goes on Schedule C and its balance sheet on Schedule F.

If the foreign corporation owns a foreign partnership interest or a disregarded entity, answering "yes" on Schedule G usually means a separate information return is also due.

Here are the main question themes:

  1. Interests in other entities. Whether the CFC holds at least a 10% interest in a foreign partnership or any interest in a trust. A "yes" here means you may also need to file Form 8865 for the partnership.
  2. Disregarded entities and branches. Whether the CFC owns any foreign disregarded entities or operates through foreign branches. Each one requires a separate Form 8858.
  3. Cost sharing arrangements. Whether the CFC participated in a cost sharing arrangement during the year. A "yes" triggers Schedule G-1, covered in detail below.
  4. Reorganizations and stock transactions. Whether the CFC acquired its own shareholder's stock for use in a triangular reorganization.
  5. Intangible property transfers. Whether the CFC received intangible property in a transfer subject to annual income inclusions under Section 367(d), which may also require Form 926 to report the initial transfer.
  6. Expatriated foreign subsidiary. Whether the CFC is an expatriated foreign subsidiary under Section 7874.
  7. Subpart F income exceptions. The largest block on Schedule G. Line 14 asks whether any exceptions, exclusions, or special rules reduced the CFC's subpart F income – covering the de minimis exception, the high-tax exception, same-country dividends, the look-through rule, and several categories of foreign base company sales income.
Pro tip
Answering "yes" on Schedule G does not change the foreign corporation's tax liability. But it tells the IRS which other forms to expect – and the separate forms each carry their own $10,000 penalty (2025) if missing.

Schedule G questions on foreign partnerships, trusts, and disregarded entities

The first several questions on Schedule G ask whether the foreign corporation has interests in other entities. Each "yes" answer typically means a separate information return is due.

  • Form 8865 for foreign partnerships. If the foreign corporation holds at least a 10% direct or indirect interest in a foreign partnership, you need to report that interest. Depending on the US person's level of control over the partnership, Form 8865 may be required as a separate attachment to your return.
  • Form 8858 for disregarded entities. If the foreign corporation owns a foreign disregarded entity – for example, a single-member foreign LLC or a branch that keeps separate books – Form 8858 must be filed for each one.

NOTE! The IRS estimates that Form 8858 takes more than 10 hours to complete, not counting recordkeeping – so build this into your filing timeline if Schedule G triggers it.

Interests in trusts

If the foreign corporation holds an interest in any trust, Schedule G asks you to report it. The reporting requirements depend on whether the trust is foreign or domestic and the nature of the interest.

The separate forms carry their own penalties. Each missing Form 8858 or Form 8865 can trigger a $10,000 penalty per form per year (2025) – the same penalty structure as Form 5471 itself.

See our guide to Form 5471 for a full overview of how these schedules and forms fit together.

Cost sharing arrangements and when Schedule G-1 is required

If the foreign corporation participated in a cost sharing arrangement during the tax year, Schedule G-1 must be attached to Form 5471. A separate Schedule G-1 is required for each arrangement.

A cost sharing arrangement under Treas. Reg. 1.482-7 is an agreement between two or more controlled participants to share the costs and risks of developing intangible property.

This includes patents, software, trade secrets, and proprietary processes.

Each participant's share of costs is proportional to its reasonably anticipated benefit share.

If a US parent company and its foreign subsidiary are jointly developing intellectual property, each company pays its share of the development costs based on the benefits it expects to receive.

When properly structured, this prevents the IRS from reallocating income between the parties under Section 482.

What to report on Schedule G-1: IDCs, RAB shares, and platform contributions

Schedule G-1 collects detailed information about each cost-sharing arrangement. Here are the main data points the form requires:

  • Intangible development costs. Total worldwide IDCs for the arrangement, and the portion allocated to the foreign corporation based on its RAB share. IDCs include all costs, in cash or in kind, that are directly identified with or reasonably allocable to the intangible development activity, including stock-based compensation, plus an arm's length rental charge for any land or depreciable tangible property used in that activity. IDCs do not include interest expense or income taxes.
  • Reasonably anticipated benefits and RAB shares. The foreign corporation's share of the anticipated additional income or cost savings from using the covered intangibles. Each participant's RAB share equals its own reasonably anticipated benefits divided by the total RAB of all controlled participants. RAB shares must total 100%.
  • Platform contribution transactions. Whether the foreign corporation made or received platform contributions during the year, the present value of those contributions, and the pricing method used under Treas. Reg. 1.482-7(g). A platform contribution is a pre-existing resource, capability, or right that one participant provides to the arrangement. The other participants must make arm's length payments – called PCT payments – in return.
  • Stock-based compensation. Total deductions for stock-based compensation, which are taken into account as IDCs under Treas. Reg. 1.482-7(d)(3).

The available pricing methods under Treas. Reg. 1.482-7(g) include the comparable uncontrolled transaction method, the income method, the acquisition price method, the market capitalization method, and the residual profit split method.

Pro tip
The IRS scrutinizes CSAs closely. If IDCs, RAB shares, and PCT payments are not internally consistent – for example, if a participant's RAB share is 40% but it bears only 20% of the IDCs – the IRS can disqualify the arrangement.

 

The result: the IRS reclassifies the transfers as taxable sales or royalty-bearing licenses under Section 482.

Form 5471 Schedule G line 14: what it asks

Line 14 is the longest section on Schedule G. It asks whether any exceptions, exclusions, or special rules applied to reduce the foreign corporation's subpart F income for the year.

Subpart F income – broadly, passive and certain mobile income earned by a CFC – is taxable to US shareholders in the year it is earned, whether or not the CFC distributes it. But the tax code contains several exceptions that can reduce or eliminate the Subpart F inclusion.

The sub-questions on line 14 cover:

  • De minimis exception. The CFC's foreign base company income plus gross insurance income fell below the lesser of 5% of gross income or $1 million.
  • High-tax exception. The income was subject to an effective foreign tax rate exceeding 90% of the maximum US corporate rate – currently 18.9%, calculated as 90% of 21% – and qualifies for exclusion under Section 954(b)(4).
  • Same-country dividends and interest. The CFC received dividends or interest from a related corporation organized and doing substantial business in the same country.
  • Same-country rents and royalties. The CFC received rents or royalties from a related corporation for property used within the CFC's country of organization.
  • Look-through rule. The CFC received dividends, interest, rents, or royalties from a related CFC where the look-through rule under Section 954(c)(6) applies.
  • Qualified banking and financing income. The CFC is an eligible entity deriving qualified income under Section 954(h).
  • Qualified insurance income. The CFC is a qualifying insurance company under Section 954(i).
  • Foreign base company sales income exceptions. Several sub-questions address whether the CFC's income from related-party sales qualifies for exceptions based on manufacturing, country of use, or agricultural commodities.

Each "yes" answer on line 14 should be consistent with the amounts reported on Schedule I. If you claim the de minimis exception but Schedule I shows subpart F income above the threshold, the IRS will flag the inconsistency.

Pro tip
Line numbers on Schedule G change between form revisions. Confirm what line 14 asks on the current form before answering – do not carry forward answers from a prior year's form without checking the current instructions.

Form 5471 Schedule G instructions: step-by-step

Filing Schedule G correctly requires confirming the filer category, gathering entity and ownership data, and cross-checking your answers against the related forms.

  1. Confirm your filer category. Schedule G is required for Categories 1c, 3, 4, 5a, and 5c. If you are unsure which category applies, see our filer categories guide.
  2. Gather entity and ownership data. Collect the foreign corporation's organizational documents, shareholder records, and information about its interests in other entities – partnerships, trusts, disregarded entities, and any cost sharing arrangements.
  3. Answer each yes/no question for the foreign corporation's annual accounting period. Go through every question on Schedule G. Each question refers to the foreign corporation's tax year, which may not match the US calendar year. Use the foreign corporation's own annual accounting period, not yours.
  4. Complete Schedule G-1 if a CSA applies. If the foreign corporation participated in a cost sharing arrangement, complete a separate Schedule G-1 for each arrangement. Attach it to Form 5471.
  5. Cross-check other schedules and forms. Compare your Schedule G answers against Schedule I for subpart F income, Schedule J for accumulated earnings and profits, and any related forms such as Form 8858, Form 8865, or Form 926. The answers on Schedule G should be consistent with what those forms report.
  6. Attach Schedule G to Form 5471 and file with your return. File the completed Schedule G with Form 5471 as part of your income tax return – Form 1040 for individuals or Form 1120 for corporations.

A common TFX client scenario

A US consultant living abroad owned 100% of a UK limited company. The company held a 25% interest in a German partnership and owned a single-member Dutch BV treated as a disregarded entity.

The consultant answered "yes" on Schedule G for both the foreign partnership interest and the disregarded entity, then attached Form 8865 and Form 8858 to the return alongside Form 5471. Missing either form would have triggered an additional $10,000 penalty per form (2025).

Forms triggered by Schedule G answers: 8858, 8865, 926, 8992, and 8621

A "yes" answer on Schedule G does not just disclose information – it often signals that a separate form is due.

Each related form carries its own filing obligation and its own penalty. Answering "yes" on Schedule G and then omitting the corresponding form is one of the most common – and most expensive – mistakes on Form 5471.

Related form What triggers it What it reports
Form 8858 CFC owns a foreign disregarded entity or operates through a foreign branch Balance sheet, income statement, and transactions with the filer for the disregarded entity
Form 8865 CFC holds an interest in a foreign partnership, and the US person meets ownership or control thresholds Income, deductions, and ownership details for the foreign partnership
Form 926 US person transfers property – including intangibles – to a foreign corporation Nature and value of the transferred property; gain recognition
Form 8992 CFC has tested income subject to GILTI Global intangible low-taxed income calculation; closely related to the Subpart F analysis on Schedule G line 14
Form 8621 CFC holds shares in a passive foreign investment company PFIC shareholder reporting; no flat $10,000 penalty, but the excess distribution rules can be substantially more costly

 

Pro tip
Form 8992 and the Section 6038 reporting overlap in practice. A "yes" on Schedule G's subpart F exception questions and the GILTI calculation on Form 8992 both draw on the CFC's tested income – keep the numbers consistent across both forms.

How Schedule G fits with the other Form 5471 schedules

Schedule G is one of several schedules on Form 5471, and the answers on each schedule should be consistent with the others.

  • Schedule E reports the CFC's income, war profits, and excess profits taxes paid or accrued. If Schedule G indicates the high-tax exception applies, the effective tax rate implied by Schedule E's numbers should support that claim.
  • Schedule H reports the CFC's current earnings and profits. The subpart F exceptions claimed on Schedule G line 14 directly affect how much of those earnings and profits flow through to the US shareholder.
  • Schedule I reports each US shareholder's pro rata share of the CFC's subpart F income, GILTI, and related amounts. If you claim the de minimis exception on Schedule G, Schedule I should show zero subpart F income.
  • Schedule J tracks the CFC's accumulated earnings and profits across tax years. Distributions reported here are affected by the subpart F determinations driven by Schedule G.
  • Schedule O reports changes in the foreign corporation's stock ownership. The ownership changes on Schedule O determine who is a US shareholder and which filer category applies – which in turn determines whether Schedule G is required.
  • Schedule P reports the US shareholder's previously taxed earnings and profits. The amounts here should be consistent with the subpart F and GILTI inclusions driven by Schedule G and Schedule I.

The consistency check: If you answer "yes" to a subpart F exception on Schedule G, the corresponding income reduction should appear on Schedule I, and the earnings and profits on Schedules H and J should reflect the same treatment.

Form 5471 due date and filing deadlines for tax year 2025

Form 5471, including Schedule G, is due with the filer's income tax return.

For tax year 2025, the standard filing deadline is April 15, 2026. US taxpayers living abroad receive an automatic 2-month extension to June 15, 2026.

Filer type Deadline
Individual – standard deadline April 15, 2026
Individual – automatic extension for taxpayers abroad June 15, 2026
Individual – extended with Form 4868 October 15, 2026
C corporation (calendar year) April 15, 2026; extended to October 15, 2026 with Form 7004

 

These extensions apply to the filing deadline, not the payment deadline. Any tax owed is still due by April 15, 2026, and interest accrues on unpaid balances from that date.

Form 5471 is always attached to the filer's income tax return – it cannot be filed as a standalone form.

Penalties for incomplete or missing Schedule G information

The IRS imposes penalties under IRC 6038 for failure to file a complete Form 5471, including Schedule G. The penalty structure has three layers.

The maximum monetary penalty is $60,000 per foreign corporation per year (2025) – $10,000 initial plus up to $50,000 in continuation penalties.

Penalty type Amount
Initial penalty $10,000 per form per year (2025)
Continuation penalty $10,000 per 30-day period after 90-day notice; capped at $50,000 additional
Maximum total monetary penalty $60,000 per form per year
Foreign tax credit reduction 10% initial under IRC 6038(c); plus 5% per additional 3-month period
Open assessment period Statute of limitations stays open until 3 years after a substantially complete form is filed; only related items stay open if reasonable cause applies

 

As The Tax Adviser reports, whether the IRS can assess this penalty directly, without first suing in court, is still being litigated outside the DC Circuit. Either way, the filing requirement and penalty amount stand – the dispute is only over how the IRS collects it.

  • Initial penalty. Failing to file Form 5471 – or filing it without a complete Schedule G – carries a $10,000 penalty per foreign corporation per annual accounting period (2025).
  • Continuation penalty. If the failure continues for more than 90 days after the IRS mails a notice, an additional $10,000 penalty (2025) applies for each 30-day period the failure continues. This continuation penalty is capped at $50,000 additional per form.
  • Foreign tax credit reduction. A filer who fails to furnish the required information also faces a 10% reduction of the foreign taxes available for credit under Sections 901 and 960. If the failure continues beyond 90 days after notice, an additional 5% reduction applies for each 3-month period. This reduction is offset dollar for dollar by the monetary penalty already paid under IRC 6038(b).
  • Open assessment period. Under IRC 6501(c)(8), the statute of limitations for the entire tax return remains open until 3 years after the IRS receives a substantially complete Form 5471. If the failure was due to reasonable cause and not willful neglect, only the items related to the missing form stay open, not the entire return. If the form is never filed, the assessment period stays open indefinitely.

The screenshot below shows a sample IRS penalty notice for a missing Form 5471 filing:

NOTE! The IRS has assessed Form 5471 penalties even in cases where the foreign corporation had no income. The penalty is for failing to disclose – not for underpaying tax.

Filers may be able to reduce or eliminate the penalty by demonstrating reasonable cause – the IRS evaluates each case based on the facts and circumstances.

Common Schedule G mistakes and how to avoid them

The most frequent errors on Schedule G are not wrong answers to the yes/no questions themselves – they are failures to follow through on what a "yes" answer requires.

  • Answering "no" to avoid triggering a related form. Some filers answer "no" to a Schedule G question because they do not want to deal with the additional form – for example, answering "no" about a disregarded entity to avoid filing Form 8858. The IRS can identify these inconsistencies by comparing Schedule G with other information on the return.
  • Skipping Schedule G-1 for a CSA. If the foreign corporation participated in a cost sharing arrangement, Schedule G-1 is mandatory. Omitting it is treated the same as filing an incomplete Form 5471.
  • Mismatched Schedule O data. The ownership percentages on Schedule O determine the filer category. If Schedule O shows 51% ownership but the filer reports as Category 5 instead of Category 4, the entire form may be treated as incorrect.
  • Answering "no" to all line 14 questions when subpart F income was reduced. If Schedule I shows reduced subpart F income but no exception is claimed on Schedule G line 14, the IRS will question the reduction.
  • Overlooking indirect ownership. Schedule G asks about the CFC's interests in partnerships, trusts, and disregarded entities. Filers sometimes overlook indirect ownership – for example, a CFC that owns a holding company that in turn owns a disregarded entity.
  • Filing a prior-year version of Schedule G. Question numbers shift between form revisions. Answering the wrong question – or answering a question that no longer exists – can result in an incomplete filing. Always use the current year's form.

Missed Schedule G or Form 5471 in prior years – options to catch up

If Form 5471 or Schedule G was missed in earlier years, the $10,000 penalty (2025) applies per form per year – and multi-year gaps compound quickly.

A filer who missed Form 5471 for two foreign corporations over three years faces up to $60,000 (2025) in initial penalties alone, before continuation penalties.

There are three main paths to catch up:

  • Delinquent international information return submission procedures. If you have not been contacted by the IRS and the failure was non-willful, you may be able to file the missing forms under the IRS's delinquent submission procedures. This requires filing the late returns with a reasonable cause statement explaining why they were not filed on time.
  • Streamlined filing compliance procedures. For taxpayers whose failure was non-willful, the streamlined procedures offer a path to compliance that may reduce or eliminate penalties. The streamlined foreign offshore procedures carry a 0% penalty for qualifying taxpayers living abroad.
  • Voluntary disclosure practice. For willful non-compliance, voluntary disclosure carries higher penalties but reduces the risk of criminal prosecution.
Pro tip
Do not file delinquent Forms 5471 without a reasonable cause statement. Filing the forms without an explanation does not trigger penalty relief – it simply starts the clock on the IRS's ability to assess the penalty.

 

Filing delinquent forms promptly can reduce penalty exposure – the sooner the filing, the narrower the window for continuation penalties.

Frequently asked questions

1. What is Schedule G on Form 5471?

Schedule G is the "other information" section of Form 5471. It contains yes/no questions about the foreign corporation's relationships, structures, cost sharing arrangements, and subpart F income exceptions. Your answers determine which additional forms the IRS expects attached to your return.

2. Who completes Schedule G?

Filers in Categories 1c, 3, 4, 5a, and 5c must complete Schedule G. Most US expats who own or control a foreign corporation file as Category 4 or Category 5.

3. What is the penalty for an incomplete Schedule G?

The initial penalty is $10,000 per foreign corporation per annual accounting period (2025). Continuation penalties of $10,000 per 30-day period (2025) can bring the total to $60,000 per form per year.

4. Is a separate Schedule G-1 needed for each cost sharing arrangement?

Yes. A separate Schedule G-1 must be completed and attached to Form 5471 for each cost sharing arrangement the foreign corporation participated in during the tax year.

5. What does line 14 on Schedule G ask?

Line 14 asks whether any exceptions reduced the CFC's Subpart F income. The sub-questions cover the de minimis exception, the high-tax exception, same-country exceptions, the look-through rule, qualified banking income, and foreign base company sales income categories.

6. Where can I find the Form 5471 Schedule G instructions?

The Schedule G instructions are included in the Instructions for Form 5471 published by the IRS. Because question numbers change between form revisions, always check the instructions for the current tax year before completing the schedule.
