Does a blank yes/no box on Schedule G really make the Form 5471 incomplete?

Yes. Section 6038(a) requires the information to be furnished, not merely a form to be lodged. The Internal Revenue Manual states that returns which are not complete and accurate are considered un-filed and that a return is not considered filed until it is complete and accurate. A blank box is therefore a failure to furnish information, even where every number elsewhere on the return is correct.

What penalties apply if Schedule G is incomplete?

The instructions impose a 10,000 US dollar penalty for each annual accounting period of each foreign corporation for failure to furnish the information required by section 6038(a) on time. If the information is not filed within 90 days after the IRS mails notice, a further 10,000 US dollars applies per 30-day period or fraction, capped at 50,000 US dollars per failure. Foreign taxes available for credit are also reduced.

Which Schedule G question do UK company owners get wrong most often?

The section 367(d) intangible property question. Founders who contributed software, a brand, a client list or documented know-how to their UK limited company on incorporation must report an annual income inclusion over the property's useful life, so the answer stays yes for years afterwards and requires a functional currency earnings and profits reduction that also flows to Schedule H. It is routinely answered no because the transfer happened long ago.

Do director's loan accounts affect the safe-haven rate questions on Schedule G?

They can. Schedule G asks separately whether the filer had a loan to or from the foreign corporation subject to the safe-haven rate rules of Regulations section 1.482-2(a)(2)(iii)(B) at a rate inside, and at a rate outside, 100 percent to 130 percent of the applicable federal rate. Establish first whether those rules apply to the loan. The UK SME transfer pricing exemption in section 166 TIOPA 2010 gives no relief from the US question.

Does a UK company ever have a Top-up Tax to report on Schedule G?

Yes, but only inside large groups. The United Kingdom has enacted the Pillar 2 rules as Multinational Top-up Tax and Domestic Top-up Tax, with registration and reporting through HMRC, so a UK member of an in-scope group can pay a Qualified Domestic Minimum Top-up Tax that must be reported in the split required by the question. An owner-managed UK company answers no, but the box must still be completed.

Form 5471 Schedule G: Yes/No Questions UK Owners Miss

Schedule G of Form 5471 is the Other Information block: a run of numbered yes/no questions that Category 1c, 3, 4, 5a and 5c filers must complete, several of which pull a separate statement, a separate schedule or an entirely separate form into the filing package when the answer is yes. It carries almost no dollar totals of its own, it takes up a fraction of the page count of Schedule C or Schedule J, and it is the single place where an otherwise accurate Form 5471 most often becomes technically incomplete.

The reason is blunt. A blank box is not a No. Section 6038(a) requires a U.S. person to furnish the information the form calls for, and the Internal Revenue Manual at www.irs.gov/irm/part20/irm_20-001-009 treats returns that are not complete and accurate as un-filed. Every figure on Schedule C can be reconciled to the statutory accounts, every pool on Schedule J can tie back to prior years, and the return can still be treated as never having been filed because question 12 was left empty and the statement behind a coded answer on line 14 was never attached.

In the returns we prepare for U.S. owners of UK limited companies, Schedule G is the schedule that takes the longest per box and generates the most queries back to the client, precisely because the questions are not about the company's numbers. They are about the shareholder's history, the group's structure, elections made years earlier and transactions the bookkeeper never saw.

What is Schedule G on Form 5471 and who has to complete it?

Schedule G is the Other Information section printed on the body of Form 5471 itself, not a separate schedule you order separately. In the current revision, dated December 2025 and published at www.irs.gov/pub/irs-pdf/f5471.pdf, it runs across three pages and is numbered from question 1 through question 21, with several questions split into lettered sub-parts. Confirm the revision you are working from at www.irs.gov/forms-pubs/about-form-5471 before you start, because the question set changes between revisions and a working paper rolled forward from a prior year will be missing questions.

The filing requirements chart in the Instructions for Form 5471 at www.irs.gov/instructions/i5471 requires Schedule G of Category 1c, 3, 4, 5a and 5c filers. The instructions add a specific carve-out: Category 1b and Category 5b filers are not required to file Schedule G for foreign-controlled section 965 specified foreign corporations and foreign-controlled CFCs respectively. For the audience this article is written for, the practical position is simple. A U.S. citizen or resident who owns a UK limited company outright, or who owns a controlling stake alongside other U.S. shareholders, is almost always a Category 4 filer, a Category 5a filer, or both, and therefore has to complete Schedule G in full.

Separate Schedule G-1, Cost Sharing Arrangement, is required of the same categories. Note that Schedule G-1 at www.irs.gov/pub/irs-pdf/f5471sg1.pdf carries a December 2023 revision date even while the parent form carries a December 2025 one. The separate schedules are not always re-issued in step with the form, and pulling the wrong vintage of a separate schedule is a filing defect in its own right.

Which questions does the current revision of Schedule G ask?

Describe them by theme rather than memorising line numbers, because the numbering moves. In the December 2025 revision the questions cluster into eight recognisable groups.

Structure and ownership. Whether the foreign corporation owned at least a 10 percent interest, directly or indirectly, in any foreign partnership; whether it owned foreign entities disregarded as separate from their owner under Regulations sections 301.7701-2 and 301.7701-3, or any foreign branches; and, new in the December 2025 revision, whether it had one or more qualified business units as defined in section 989(a) with a functional currency different from its owner.
Payments between the filer and the corporation. Whether the filer paid or accrued a base erosion payment under section 59A(d) to the foreign corporation, or had a base erosion tax benefit under section 59A(c)(2); and whether the foreign corporation paid or accrued interest or a royalty for which a deduction is disallowed under section 267A, the hybrid arrangement rule.
Foreign-derived items. Whether the filer is claiming a foreign-derived intangible income deduction under section 250 in respect of transactions with the foreign corporation, with gross receipts from sales of general property, sales of intangible property and services all reported separately.
Cost sharing. Whether the foreign corporation was a participant in any cost sharing arrangement during the tax year.
Transfers and reorganisations. Whether the corporation purchased stock or securities of a shareholder for use in a triangular reorganization within the meaning of Regulations section 1.358-6(b)(2) after April 25, 2014; whether it received intangible property in a prior or current year for which a U.S. transferor must report a section 367(d) annual income inclusion; and whether it was an expatriated foreign subsidiary under Regulations section 1.7874-12(a)(9).
Foreign tax integrity. Whether the corporation paid or accrued any foreign tax disqualified for credit under section 901(m), and whether it paid or accrued foreign taxes to which section 909 applies or treated previously suspended taxes as no longer suspended.
Disclosure and disallowance. Whether the corporation participated in a reportable transaction as defined in Regulations section 1.6011-4; whether it has interest expense disallowed under section 163(j); and whether it has previously disallowed section 163(j) interest carried forward.
Related-party terms and recent additions. The safe-haven rate questions on loans between the filer and the corporation under Regulations section 1.482-2(a)(2)(iii)(B); the covered debt instrument questions under Regulations section 1.385-3; the extraordinary reduction questions concerning a controlling section 245A shareholder; the Top-up Tax question; and, new in the December 2025 revision, a question on whether any increase or decrease to earnings and profits was attributable to a transaction described in section 304.

There is also a question on interests the corporation may hold in other vehicle types, which falls outside the corporate and partnership scope of this article and is dealt with separately. Everything discussed below is confined to corporate and partnership fact patterns.

Which Schedule G answers force a statement, a schedule or another form?

This is the part that gets missed. A yes on Schedule G is frequently not the end of the work; it is the trigger for something that has to be physically attached to the return. Verified against the instructions at www.irs.gov/pub/irs-pdf/i5471.pdf, the current revision attaches consequences to a yes as follows.

Foreign partnership interest of at least 10 percent: attach a statement listing, for each foreign partnership, the name and EIN if any, which of Form 1042, Form 1065 or Form 8804 the partnership filed for its tax year ending with or within the corporation's tax year, the name of the partnership representative if any, and the beginning and ending dates of the partnership's tax year.
Foreign disregarded entities or foreign branches: a Category 4, 5a or 5c filer is generally required to attach Form 8858 for each entity or branch, and amounts on the Form 8858 schedules feed the equivalent Form 5471 schedules. See www.irs.gov/forms-pubs/about-form-8858. A filer outside Categories 1b, 4 and 5 attaches a statement in lieu of Form 8858 giving the name of the entity or branch, the country under whose laws it was organised, and its EIN if any.
Qualified business units with a different functional currency: enter the number of Forms 8964-TRA attached to the Form 5471.
Base erosion payments: complete the two follow-on entries for the total base erosion payments and the total base erosion tax benefits, but only where the corporation is a related party within the meaning of section 59A(g) and the filer actually made or accrued such a payment.
Section 267A disallowance: enter the total amount of the disallowed deductions, excluding amounts attributable to interest or royalties paid or accrued by a U.S. taxable branch of the corporation, which belong on Form 1120-F.
FDII: complete the three gross receipts entries, translated into U.S. dollars at the average exchange rate for the corporation's tax year under section 989(b), and cross-check them to Form 8993.
Cost sharing arrangement: complete a separate Schedule G-1 for each arrangement in which the corporation participated during the year.
Section 367(d) intangible property: enter the functional currency amount of the earnings and profits reduction under section 367(d)(2)(B) for the year, and carry the same figure to Schedule H as a net subtraction.
Expatriated foreign subsidiary: attach a statement giving the name and EIN of the domestic corporation or partnership defined in Regulations section 1.7874-12(a)(6) and the relationship of the foreign corporation to it.
Reportable transaction: attach Form 8886 where Regulations section 1.6011-4(c)(3)(i)(G) requires it.
Election to close the tax year following an extraordinary reduction: a controlling section 245A shareholder filing the Form 5471 must attach an Elective Section 245A Year-Closing Statement under Regulations section 1.245A-5(e)(3)(i)(C) containing the information required by Regulations section 1.245A-5(e)(3)(i)(D).

One formatting rule from the instructions is worth quoting in practice because it is broken constantly. Where the information required in a section exceeds the space provided, you must not write See attached in the section and put everything on a separate sheet. You complete every entry space in the section and attach the remainder on additional sheets that conform to the IRS version of that section.

Line 14 is twenty-three questions hiding behind one tick box

The most under-prepared item on the schedule is the question that asks whether you answered yes to any of the questions in the instructions for line 14. On the form it is a single tick box with a short entry field. In the instructions it is a multi-page table of twenty-three separate questions, each with a two to four letter code and each with a prescribed statement to attach. If any of them is a yes, you tick the box, enter the corresponding codes in capital letters separated by spaces, and attach the statement described in the table for each code.

The table covers the exclusions and reductions that keep amounts out of subpart F income: the de minimis rule, the high tax exception, deductions taken into account, active and hedging commodity gains, business needs foreign currency gains, active rents and royalties, certain export financing, regular dealers, securities dealers, active financing income, active insurance income, the earnings and profits limitation, and a residual pro rata share category. There is also an explicit catch-all asking whether the U.S. person is relying on any exception, exclusion or provision not listed to reduce amounts reported or reportable as subpart F income.

Two of these codes matter for almost every UK owner-managed company. The de minimis code applies where the sum of the CFC's foreign base company income, determined without regard to deductions, and gross insurance income is less than the lesser of 5 percent of gross income or 1 million U.S. dollars. A UK trading company with nothing more exotic than a few thousand pounds of bank deposit interest has foreign personal holding company income, and that income is very often excluded by the de minimis rule. That is a yes, and it needs a code and a statement of the amount excluded. The high tax code applies where the corporation received an item of income subject to an effective foreign rate greater than 90 percent of the maximum rate specified in section 11. Whether a UK company clears that bar is a calculation, not an assumption, and a company paying the 19 percent small profits rate sits in a materially different position from one paying the 25 percent main rate. UK rates and the profit thresholds are set out at www.gov.uk/corporation-tax-rates.

The December 2025 revision also split one of the pro rata share questions into two parts and added a Pro Rata Share Transition Rule code, tied to section 70354(c)(2)(A) of the OBBBA and Notice 2025-75, covering dividends paid or deemed paid by the CFC that the filer nonetheless treats as a dividend for section 951(a)(2)(B) purposes. The statement required for that code is unusually demanding: it has to explain why the filer is entitled to that treatment and how the filer determined that the dividend increased the taxable income of a U.S. person subject to federal income tax. If your line 14 working paper predates this revision, it is missing that question entirely.

Schedule G-1 and the cost sharing arrangement question

A yes to the cost sharing question means a separate Schedule G-1 for each arrangement in which the foreign corporation participated during the year, with all amounts reported in U.S. dollars. Schedule G-1 asks for a brief description of the arrangement, whether the corporation became a participant during the year, whether the arrangement was in effect before January 5, 2009, the corporation's share of reasonably anticipated benefits expressed as a percentage, whether a U.S. taxpayer made platform contributions as defined in Regulations section 1.482-7(c) and their present value, and which method under Regulations section 1.482-7(g) was used to price the platform contribution transaction. The method options are the comparable uncontrolled transaction method, the income method, the acquisition price method, the market capitalization method, the residual profit split method and an unspecified method. It then asks for stock-based compensation deductions and for total intangible development costs and the share allocable to the foreign corporation.

Owner-managed UK companies rarely have a formal cost sharing arrangement, and the honest answer is usually no. The trap is the UK company that develops software or brand assets alongside a U.S. affiliate under an informal cost-recharge that nobody has documented. Answering no because there is no signed agreement, when the economics look like shared intangible development, is the kind of answer that does not survive examination.

Why an unanswered Schedule G question makes the whole Form 5471 incomplete

This is the point most guidance skates over. Form 5471 is not a tax computation, it is an information return, and the obligation under section 6038(a) is to furnish information. The penalty in the instructions is expressed accordingly: a 10,000 U.S. dollar penalty is imposed for each annual accounting period of each foreign corporation for failure to furnish the information required by section 6038(a) within the time prescribed. Nothing in that sentence is limited to unfiled forms. A form that arrives with the required information missing has not furnished it.

The Internal Revenue Manual makes the position explicit. Returns submitted that are not complete and accurate are considered un-filed, and where an examiner secures a return that is incomplete or inaccurate, the taxpayer is to be told that the return is not considered filed until it is complete and accurate. That language is at www.irs.gov/irm/part20/irm_20-001-009.

The consequences that follow are the ones worth planning around.

The continuation penalty. If the information is not filed within 90 days after the IRS mails a notice of the failure, an additional 10,000 U.S. dollar penalty per foreign corporation applies for each 30-day period, or fraction of one, during which the failure continues after the 90-day period, limited to a maximum of 50,000 U.S. dollars for each failure.
The foreign tax credit haircut. Any person who fails to file or report all of the required information within the time prescribed is subject to a reduction of 10 percent of the foreign taxes available for credit under sections 901 and 960, with an additional 5 percent reduction for each three-month period, or fraction of one, that the failure continues after the 90-day period, subject to the limits in section 6038(c)(2).
The open statute. Under section 6501(c)(8), the assessment period does not close until three years after the information required under section 6038 is actually provided to the IRS. A return with a defective Schedule G can leave the limitation period open long after the taxpayer believes the year is closed.
Relief exists but has to be claimed. The instructions point to Regulations sections 1.6038-1(j)(4) and 1.6038-2(k)(3) for alleviation of the foreign tax credit reduction in certain cases, and reasonable cause remains the route on the fixed penalties.

The asymmetry is what makes Schedule G worth disproportionate attention. Getting a Schedule J pool wrong by a few thousand pounds is a correction. Leaving three yes/no boxes empty is a potential 10,000 U.S. dollar exposure per company per year, a credit reduction, and a year that never closes.

Which Schedule G questions does a typical UK owner-managed company answer yes to?

Take the common fact pattern: a U.S. citizen resident in the United Kingdom who owns 100 percent of a UK limited company that trades in the UK, has a handful of employees, holds cash on deposit, and pays its owner a small salary and dividends. Working the schedule in order, here is where the answers actually land.

Foreign partnership interest: usually no, but yes where the company is a member of a UK partnership or of an entity classified as a partnership for U.S. purposes. Check the classification before answering, because it drives the attached statement.
Disregarded entities and foreign branches: usually no for a single-company UK structure, and yes where the company operates through a branch outside the UK or holds a subsidiary that has checked the box to be disregarded. A yes here means Form 8858, not a note in the file.
Qualified business units with a different functional currency: usually no for a sterling-only company, and yes where the company runs, for example, a euro-functional or dollar-functional branch. This question is new, so a rolled-forward working paper will simply have no answer in the box.
Base erosion payments: no. Section 59A is aimed at large corporate taxpayers, and an individual filing Form 5471 for an owner-managed company is not in scope. The box still has to be ticked no.
Section 267A interest or royalty disallowance: usually no, but this is the question to think about where the company pays interest on a director's loan account or a related-party royalty, and the recipient's treatment could produce a deduction without a corresponding inclusion.
FDII: no for an individual filer. Section 250 is a corporate deduction, so this becomes live only where a U.S. corporation sits above the UK company.
Cost sharing arrangement: usually no, subject to the informal cost-recharge point above.
Triangular reorganization stock purchases: no in the ordinary case.
Section 367(d) intangible property: yes more often than owners expect. See below.
Expatriated foreign subsidiary: no absent an inversion.
Reportable transactions: usually no, but confirm against Regulations section 1.6011-4 rather than assuming.
Section 901(m) and section 909 foreign taxes: usually no for a standalone company, and worth a second look where the UK company is part of a group or has been acquired.
Line 14 coded exclusions: very often yes, most commonly on the de minimis rule.
Section 163(j) disallowed and carried-forward interest: no unless the UK company is itself required to file a U.S. income tax return such as Form 1120-F. The instructions frame both questions that way.
Extraordinary reduction and the section 245A year-closing election: no for an individual shareholder, since section 245A is a corporate participation exemption.
Safe-haven rate loans: the question most often answered carelessly. See below.
Covered debt instruments under Regulations section 1.385-3: the instructions restrict these lines to filers that are domestic corporations, and direct that debt instruments issued, and distributions or acquisitions occurring, before April 5, 2016 are left out of account.
Top-up Tax: no for an owner-managed company, but a genuine yes inside large groups with UK members.
Section 304 earnings and profits movements: no in a steady year, and a real risk in a restructuring year.

The three answers UK owners most often get wrong

First, the section 367(d) question. A founder who set up a UK limited company and transferred existing intellectual property into it, whether software, a brand, customer lists or documented know-how, in an exchange under section 351 or section 361, is required to report an annual income inclusion over the useful life of that property. The question asks whether the corporation received intangible property in a prior year or the current year for which the U.S. transferor is required to report a section 367(d) annual income inclusion. It is not a question about this year's transactions. It stays yes for years, and it requires the functional currency earnings and profits reduction under section 367(d)(2)(B) to be entered and carried through to Schedule H as a net subtraction. In practice this is where an incorporation that happened five years ago quietly makes every subsequent Schedule G wrong.

Second, the safe-haven rate loan questions. Owner-managed UK companies run director's loan accounts as a matter of routine, in both directions, and frequently at zero interest or at a UK administrative rate that has nothing to do with the U.S. applicable federal rate. Schedule G asks two questions: whether the filer had a loan to or from the corporation to which the safe-haven rate rules of Regulations section 1.482-2(a)(2)(iii)(B) apply and used a rate inside the safe-haven range of 100 percent to 130 percent of the applicable federal rate for the relevant term, and whether the filer had such a loan and used a rate outside that range. Both boxes must be answered. The threshold work is establishing whether the safe-haven rules apply to the loan at all, which is not automatic, and only then which box is yes. Note that the UK side gives no comfort here: section 166 TIOPA 2010 exempts most transactions of small and medium-sized enterprises from UK transfer pricing, as explained at www.gov.uk/hmrc-internal-manuals/international-manual/intm412070, so a UK owner may have had no domestic reason ever to price the loan. The U.S. question still has to be answered.

Third, line 14. Ticking no because subpart F income came out at zero is the classic error. Zero subpart F income is very often the result of an exclusion, and the exclusion is exactly what line 14 is asking you to disclose and code.

The Top-up Tax question and the UK Pillar 2 regime

The Top-up Tax question asks whether the foreign corporation paid or accrued any Top-up Tax during the year, and, if so, splits the amount between the Income Inclusion Rule, the Qualified Domestic Minimum Top-up Tax and the UTPR, or taxes similar to each. The instructions ground the question in the OECD GloBE Model Rules and the 15 percent effective tax rate test.

This matters for UK filers because the United Kingdom has actually enacted the regime, as Multinational Top-up Tax and Domestic Top-up Tax, with a registration and reporting mechanism set out at www.gov.uk/guidance/register-to-report-pillar-2-top-up-taxes. A UK company inside a large in-scope group can therefore have a genuine QDMTT figure to report on Schedule G, and it will not appear anywhere in the company's corporation tax computation in the form the question expects. For an owner-managed UK company the answer is no, because these taxes are directed at large groups, but the box is not optional.

Worked example: a US citizen with a London consultancy

The following is an illustration, not a client file, and the figures are assumed. A U.S. citizen resident in London owns all of a UK limited company incorporated four years ago. On incorporation she contributed a proprietary methodology and client list she had developed personally in the United States. The company has revenue of 900,000 pounds, a small profits position below the main rate threshold in its first year and above it since, and it holds 300,000 pounds on deposit generating roughly 12,000 pounds of interest. She has a director's loan account that ran overdrawn for part of the year at no interest. All figures are assumed for illustration and no exchange rate is applied to them.

Her Schedule G is not a page of noes. The intangible property contributed on incorporation makes the section 367(d) question a yes, with a functional currency earnings and profits reduction to compute and carry to Schedule H. The deposit interest is foreign personal holding company income, and if it falls below the lesser of 5 percent of gross income or 1 million U.S. dollars it is excluded by the de minimis rule, which makes line 14 a yes with a de minimis code and a statement of the excluded amount. The director's loan account requires the safe-haven questions to be worked through rather than defaulted to no. Everything else is a no, but every no has to be recorded. On a return prepared without that walkthrough, three of those items would have been left blank, and the return would be incomplete for section 6038 purposes despite Schedules C, E, H, I, J and P all being right.

How we complete Schedule G in the returns we prepare

Pull the current form and instructions from www.irs.gov/pub/irs-pdf/f5471.pdf and www.irs.gov/pub/irs-pdf/i5471.pdf at the start of every filing season and diff the question set against the prior year, rather than rolling forward last year's template.
Answer every question explicitly, in writing, including the noes, and hold the reasoning in the file. A no with a documented basis is a defensible answer; a blank is not an answer at all.
Work the line 14 table as twenty-three separate questions against the subpart F computation, not as one tick box, and draft each required statement as you go.
Treat the incorporation history as a standing item. Section 367(d) inclusions, historic elections and reorganisations persist across years and are the most common source of a wrong answer.
Prepare the triggered attachments before finalising the schedule: Form 8858, Form 8886, Schedule G-1, the foreign partnership statement, the expatriated foreign subsidiary statement and the section 245A year-closing statement each have prescribed content.
Complete every entry space in a section and continue on conforming additional sheets, rather than writing See attached, which the instructions specifically prohibit.

If a Schedule G was filed blank in an earlier year

An incomplete Schedule G in a prior year is a live exposure, not a historical curiosity, because section 6501(c)(8) keeps the assessment period open until three years after the information is furnished. The practical route is to establish the correct answers for each open year, prepare the triggered statements and schedules, and file an amended return carrying a complete Form 5471 with a reasonable cause statement where the facts support one. Doing that before the IRS mails a notice of failure matters, because the 90-day clock on the continuation penalty only starts once that notice has been issued. Where the same defect runs across several years and several companies, the arithmetic on the fixed penalty alone justifies a systematic remediation rather than a year-by-year one.

Schedule G is a small schedule that behaves like a large one. It carries no revenue, no earnings and profits and no credit computation, and it can still be the reason a return is treated as never filed. Prepare it as a set of evidenced answers with their attachments, not as a page to be ticked at the end.
