IRS Streamlined Filing Compliance: GILTI and HNW Families
IRS Streamlined Filing Compliance on GILTI for UK Owners
A US citizen who owns or controls a UK private limited company — whether a trading company, a holding structure, or a professional services vehicle — faces one of the most complex provisions in the post-TCJA US international tax regime: the Global Intangible Low-Taxed Income charge under IRC Section 951A, which requires the US shareholder to include their pro-rata share of the UK company's net tested income in their US gross income each year, regardless of whether any dividend has been paid. Furthermore, IRS streamlined filing compliance through the IRS Streamlined Foreign Offshore Procedures has become directly relevant to HNW UK-resident US citizens who own UK companies because the GILTI inclusion obligation — and the related Form 5471 reporting requirement for controlled foreign corporations — is one of the most systematically missed compliance obligations in the US expat community, and one that carries a minimum $10,000 per Form 5471 per year penalty for non-filing.
This article is written for US citizens who are UK residents and who own or control UK limited companies — whether wholly owned or held with other shareholders — and who want to understand how the GILTI high-tax exclusion election reduces or eliminates the US tax on UK company profits, and how IRS streamlined filing compliance addresses the prior-year non-filing of Form 5471 and the missed GILTI elections that have accumulated during years of UK company ownership.
What Is IRS Streamlined Filing Compliance on GILTI?
IRS streamlined filing compliance in the GILTI context refers to the application of the Streamlined Foreign Offshore Procedures to correct non-wilful failures to file Form 5471 (the annual information return for US persons with interests in foreign corporations), Form 8992 (the GILTI calculation form), and the underlying Form 1040 returns that should have included the GILTI income for each year. Furthermore, GILTI — defined under IRC Section 951A as a US shareholder's pro-rata share of a controlled foreign corporation's net tested income less a 10% return on qualified business asset investment — is an annual inclusion that operates like a deemed dividend from the CFC to the US shareholder, regardless of whether the UK company has actually distributed any profits. Specifically, for a UK-resident US citizen who owns a UK trading company that generates £150,000 of annual profit and pays UK corporation tax at 25%, the GILTI inclusion creates a potential additional US tax charge on those already UK-taxed profits — a charge that the GILTI high-tax exclusion election is designed to eliminate where the UK effective tax rate exceeds the GILTI high-tax threshold of 18.9%.
The IRS guidance on GILTI and the high-tax exclusion election is at https://www.irs.gov/businesses/international-businesses/gilti-high-tax-exclusion. The IRS Form 5471 instructions are at https://www.irs.gov/forms-pubs/about-form-5471.
Why GILTI Compliance Matters More for UK Owners in 2026
The UK Corporation Tax Rate and the GILTI High-Tax Threshold
The UK's main corporation tax rate of 25% — applicable to companies with profits above £250,000 since April 2023 — substantially exceeds the GILTI high-tax exclusion threshold of 18.9% (90% of the US corporate rate of 21%). Furthermore, this rate differential means that most UK private limited companies with profits above the £250,000 small profits threshold pay UK corporation tax at a rate that qualifies for the GILTI high-tax exclusion election — which, when properly made, excludes the UK company's profits entirely from the US shareholder's GILTI inclusion. Consequently, for most HNW UK-resident US citizens who own actively trading UK companies subject to the 25% UK corporation tax rate, the GILTI high-tax exclusion election eliminates the GILTI charge — but only if the election is correctly made on a timely filed Form 8992, which requires a Form 5471 to have been filed for the CFC. Additionally, for companies with profits between £50,000 and £250,000 — subject to the UK small profits marginal relief rate of 19% to 25% — a specific rate calculation is required to determine whether the effective UK rate exceeds the 18.9% threshold for the high-tax exclusion. According to https://www.aicpa.org, the GILTI high-tax exclusion election is the most impactful planning tool available to US shareholders of UK companies subject to the standard 25% corporation tax rate.
Form 5471: The Most Commonly Missed International Return
Form 5471 must be filed annually by every US person who is an officer, director, or at least 10% shareholder of a foreign corporation — including a UK private limited company — regardless of whether any GILTI inclusion arises in that year. Furthermore, the minimum penalty for failure to file Form 5471 is $10,000 per form per year, rising to $50,000 where the failure continues after IRS notification — and the penalty applies even where no tax is ultimately owed, since Form 5471 is an information return rather than a tax return. Consequently, a UK-resident US citizen who has owned a UK limited company for eight years without filing Form 5471 has accumulated a theoretical minimum penalty exposure of $80,000 — a figure that makes IRS streamlined filing compliance through the streamlined procedures a critical priority for any UK company owner who has never filed the return. https://www.icaew.com has highlighted non-compliance with Form 5471 among US-citizen UK company directors as one of the most urgent cross-border compliance issues facing the UK professional community.
The Pillar Two Interaction with GILTI Post-2024
The OECD's Pillar Two global minimum tax framework — which the UK implemented through the Multinational Top-up Tax from January 2024 — interacts with the GILTI regime, affecting the high-tax exclusion election analysis for larger UK corporate groups. Furthermore, where a UK company is subject to the Pillar Two top-up tax because its effective tax rate falls below 15% in any jurisdiction within the group, the GILTI high-tax exclusion election analysis must account for any Pillar Two top-up tax paid as an additional foreign tax for the purposes of confirming whether the effective rate exceeds the 18.9% threshold. Consequently, HNW families with UK corporate structures that include multiple jurisdictions — where some subsidiaries may have effective rates below 15% — must conduct a jurisdiction-by-jurisdiction analysis of both the Pillar Two exposure and the GILTI high-tax exclusion availability. This task requires the specific expertise of IRS streamlined filing compliance practitioners who understand both the US GILTI regime and the UK Pillar Two implementation.
GILTI High-Tax Exclusion: How It Works for UK Companies
The Tested Income Calculation for a UK Company
GILTI is calculated at the tested unit level — typically, each CFC separately — as the gross tested income less allocated deductions, minus 10% of the qualified business asset investment. Furthermore, gross tested income is the CFC's gross income less income excluded from the GILTI regime — including Subpart F income, income effectively connected with a US trade or business, and income from high-taxed income qualifying for the high-tax exclusion. Specifically, where the GILTI high-tax exclusion election is made, any item of gross income subject to a foreign effective tax rate above 18.9% is excluded from gross tested income entirely — removing it from the GILTI calculation before the tested income figure is determined. Consequently, for a UK company that pays 25% UK corporation tax on all its profits, electing the high-tax exclusion removes all of the company's income from the GILTI calculation, producing a zero GILTI inclusion and eliminating the US tax on UK company profits that have already borne UK corporation tax at a rate substantially above the high-tax threshold.
The Section 962 Election as an Alternative
Where the GILTI high-tax exclusion election is not available — for example, because the UK company's effective rate is below 18.9% due to the use of UK research and development tax credits or other reliefs that reduce the effective UK rate below the threshold — a US individual shareholder can instead elect to be treated as a corporation for GILTI purposes under IRC Section 962. Furthermore, the Section 962 election allows the individual to apply the 21% US corporate rate to the GILTI inclusion rather than the individual's marginal rate of up to 37%, and to claim an indirect foreign tax credit for the underlying UK corporation tax paid by the CFC — a credit mechanism not otherwise available to individual shareholders on GILTI inclusions. Additionally, the Section 962 election yields a different tax cost than the high-tax exclusion election in most scenarios, and the optimal election depends on the effective UK corporation tax rate, the individual's US marginal tax rate, and the overall structure of the HNW family's UK corporate holdings. Consequently, HNW families with UK companies that are close to the 18.9% high-tax threshold — in the marginal relief band between 19% and 25% — must model both elections before choosing which to make on the annual return.
The High-Tax Exclusion Election Is Annual and Revocable
The GILTI high-tax exclusion election under Reg. Section 1.951A-2(c)(7) is made annually on Form 8992 and applies to all CFCs of the US shareholder in all jurisdictions for the year of election — it cannot be made selectively for some CFCs and not others. Furthermore, the election can be revoked in a subsequent year without IRS consent, but once revoked, it cannot be re-elected for five years — a restriction that requires careful planning before the election is first made or first revoked, since changing the election has consequences for multiple future years. Additionally, where the election has not been made in prior years because Form 5471 and Form 8992 were not filed, the IRS streamlined filing compliance submission must retroactively elect the high-tax exclusion for each covered year by including the election on the original or amended Form 8992 for each year — an important aspect of the streamlined submission that reduces the GILTI inclusion and therefore the US tax for each covered year.
Streamlined Filing for UK Company Owners: Steps
Step 1 — Confirm the CFC status of each UK company.
Confirm whether each UK company is a controlled foreign corporation — defined as a foreign corporation in which US persons own more than 50% of the total combined voting power or total value — and identify every US person who is a 10% or greater shareholder, officer, or director of each UK company. Furthermore, for a UK-resident US citizen who owns 100% of a UK trading company, the company is clearly a CFC for every year of ownership, and Form 5471 is required for every year from the first year the ownership threshold was met. Additionally, where the UK company is jointly owned by a US citizen and a UK national, confirm the exact ownership percentages and whether the US person's combined voting power or value exceeds 50% — either alone or attributed from related parties — since the CFC determination affects whether GILTI applies at all to the non-US shareholders' portion of the company.
Step 2 — Reconstruct the UK company's financial data for each covered year.
Obtain the UK company's statutory accounts, corporation tax computations, and CT600 returns for each year in the three-year income tax covered period and the six-year FBAR covered period. Furthermore, extract the UK-taxable profit and the UK corporation tax paid for each year from the CT600, since these figures form the basis for the tested income calculation and the effective rate determination for the high-tax exclusion election. Additionally, identify the QBAI — the adjusted basis of depreciable tangible property used in the CFC's trade or business — for each year, since the 10% QBAI return is subtracted from tested income in the GILTI calculation and reduces the inclusion even where the high-tax exclusion does not apply. The IRS Form 5471 instructions, including the tested income calculation methodology, are available at https://www.irs.gov/forms-pubs/about-form-5471.
Step 3 — Calculate the effective UK tax rate for the high-tax exclusion analysis.
Calculate the effective UK corporation tax rate for each tested unit in each covered year as the UK corporation tax paid divided by the net tested income before the high-tax exclusion — and confirm whether this rate exceeds the 18.9% GILTI high-tax threshold. Furthermore, where the effective UK rate is above 18.9% — as it will be for most UK trading companies subject to the 25% main rate — elect the GILTI high-tax exclusion on Form 8992 for that year, excluding the UK company's tested income entirely from the GILTI calculation. Additionally, where the effective UK rate is in the marginal relief band and may fall below 18.9% in some years, model both the high-tax exclusion and the Section 962 elections to confirm which produces the lower combined US and UK tax for the affected years.
Step 4 — Prepare Form 5471 for each covered year.
Prepare Form 5471 for each CFC for each year in the covered period, completing all required schedules — Schedule E for UK income taxes paid, Schedule I for Subpart F income, Schedule J for accumulated earnings and profits, and Schedule P for previously taxed earnings — using the UK statutory accounts as the primary source data. Furthermore, complete Form 8992 for each year to report the GILTI calculation, and make the high-tax exclusion election for years in which the effective UK rate exceeds the threshold. Additionally, attach the Form 5471 and Form 8992 to the original or amended Form 1040 for each covered year and include the GILTI inclusion (where any arises after the high-tax exclusion) in the US gross income for that year at the appropriate rate.
Step 5 — Draft the non-wilfulness narrative for Form 5471 non-filing.
Prepare the Form 14653 non-wilfulness narrative addressing the specific circumstances of the Form 5471 and GILTI non-reporting — typically the UK company owner's reliance on UK accountants who prepared the CT600 without any awareness of the US person's separate obligation to file Form 5471, and the absence of any US disclosure requirement in the UK Companies House filing process. Furthermore, the narrative should address why the US shareholder believed UK corporation tax compliance — through the CT600 and annual accounts — constituted sufficient reporting of the UK company's income, and why the GILTI regime was unknown or misunderstood until the cross-border compliance gap was identified. The IRS streamlined procedures guidance is at https://www.irs.gov/individuals/international-taxpayers/streamlined-filing-compliance-procedures.
Case Study: US Citizen in London, UK Limited Company
Our team was engaged by a US citizen who had lived in London for eleven years and who was the sole owner of a UK management consultancy incorporated as a private limited company. The company had generated average annual profits of approximately £180,000 over the prior three years, paying UK corporation tax at the 25% main rate of approximately £45,000 per year. He had engaged a UK accountant for the company's annual accounts and CT600. Still, he had never been advised of his obligation to file Form 5471 as a US person owning a foreign corporation, and had never filed a US tax return for any year of UK residence.
After confirming the CFC status of the UK company — the client owned 100% of the shares and was the sole director, making him a Category 4 filer under Form 5471 classification — we confirmed Form 5471 was required for every year since incorporation, eleven years in total. Furthermore, we calculated the effective UK corporation tax rate for each of the three covered years as 25% of accounting profit — well above the 18.9% GILTI high-tax threshold — and confirmed that the GILTI high-tax exclusion election was available and effective for all three years, eliminating the GILTI inclusion for each year. Additionally, the Form 5471 non-filing penalty exposure for the eight years outside the streamlined covered period was significant. Still, the streamlined procedures resolved the three covered years and provided a clear disclosure position for the earlier years through the non-wilfulness narrative.
We prepared three years of original Form 1040 returns using streamlined procedures, each accompanied by the relevant Form 5471 with the high-tax exclusion election made on Form 8992, resulting in a zero GILTI inclusion for all three covered years. Furthermore, the US income tax for each year reflected only the client's UK employment income from the company as a director's salary — approximately £80,000 per year — after claiming the foreign income exclusion under IRC Section 911 on Form 2555, with the foreign tax credit on Form 1116 providing relief for the UK income tax on the salary above the exclusion limit. The 5% streamlined penalty on the highest aggregate balance of the UK business account and personal accounts — approximately $340,000 — produced a penalty of $17,000. The most significant outcome was structuring the going-forward compliance program so that Forms 5471 and 8992, with the high-tax exclusion election, are filed annually alongside the personal Form 1040, eliminating any future GILTI exposure.
Common Mistakes with GILTI and UK Company Ownership
Mistake 1 — Not Filing Form 5471 at All
The most fundamental mistake is the complete absence of Form 5471 for the years of UK company ownership — a situation that applies to the vast majority of UK-resident US citizens who own UK limited companies, because the UK company formation and compliance process does not indicate the US person's separate reporting obligation. Furthermore, the $10,000 minimum penalty per form per year applies regardless of whether any tax is owed, making the accumulated penalty exposure very large for long-standing company owners. The correct approach requires filing Form 5471 for each year since the first year of ownership, using streamlined procedures to correct prior years, and establishing annual filing from the current year onwards. IRS Form 5471 guidance is at https://www.irs.gov/forms-pubs/about-form-5471.
Mistake 2 — Not Making the High-Tax Exclusion Election
Where Form 5471 is filed but the GILTI high-tax exclusion election is not made on Form 8992, the full GILTI inclusion flows through to the US shareholder's income and is taxed at marginal rates — producing a US tax charge on UK company profits that have already paid 25% UK corporation tax, without any credit mechanism for the underlying corporate tax. Furthermore, the high-tax exclusion election is not automatic — it must be made affirmatively on Form 8992 each year, and a Form 8992 that reports the GILTI inclusion without the election produces a US tax bill that is entirely avoidable for most UK companies. The correct approach requires making the election on every annual Form 8992 for years in which the effective UK rate exceeds 18.9%.
Mistake 3 — Not Including the UK Company in FBAR Reporting
The UK bank account of the CFC — whether held in the company's name or in the owner's name on the company's behalf — may be a foreign financial account for FBAR purposes if the US person has a financial interest in, or signature authority over, the account. Furthermore, a US citizen who is the sole director and shareholder of a UK company has both a financial interest in and signature authority over the company's UK business account, making that account reportable on the FBAR for every year the account balance exceeded $10,000. The correct approach is to include the UK company's business bank account in the six-year FBAR streamlined package, along with all personal UK accounts.
Mistake 4 — Misapplying the Section 962 Election
Some practitioners apply the Section 962 election to all UK company owners as a default, without first confirming whether the GILTI high-tax exclusion election produces a better outcome. Furthermore, for a UK company paying 25% corporation tax, the high-tax exclusion eliminates GILTI entirely — producing zero US tax on the company's profits — while the Section 962 election reduces the US tax to 21% after a partial indirect foreign tax credit, still producing a residual US tax charge. The correct approach requires modeling both elections for each year before deciding which to make, since the high-tax exclusion is strictly preferable to Section 962 for UK companies paying the 25% main rate. IRS GILTI guidance is at https://www.irs.gov/businesses/international-businesses/gilti-high-tax-exclusion.
Mistake 5 — Not Identifying Subpart F Income Separately from GILTI
GILTI and Subpart F income are distinct categories of CFC income, each requiring separate identification and reporting on Form 5471 and the related schedules. Furthermore, a UK company that earns passive income — interest, dividends, rents — alongside its active trading income must separately identify the passive income as potential Subpart F income under IRC Section 954, since Subpart F income is includible in the US shareholder's income under different rules from GILTI and is not eligible for the high-tax exclusion election in the same way. The correct approach requires a separate Subpart F analysis for each year of UK company ownership, alongside the GILTI calculation, to ensure that both categories of income are correctly reported.
Mistake 6 — Not Planning for the Five-Year Re-Election Restriction
The GILTI high-tax exclusion election can be revoked in a subsequent year, but once revoked, it cannot be re-elected for five years. Furthermore, a UK company owner who revokes the election in a year where the UK effective rate temporarily falls below 18.9% — due to a large R&D credit or a capital allowance spike — may find that the election is unavailable for the following five years when the effective rate returns above the threshold. The correct approach requires planning the election decision over a multi-year horizon, considering the company's expected UK effective rate trajectory before revoking an election that may not be available again when most needed.

Conclusion
The GILTI high-tax exclusion election is the most important planning tool available to US-citizen owners of UK limited companies,. Yet, itis entirely inaccessible to the vast majority of UK-resident US citizens who own UK companies, as they have never filed Form 5471 and have never known the election existed. Furthermore, IRS streamlined filing compliance through the IRS Streamlined Foreign Offshore Procedures provides the correction route that simultaneously addresses the missed Form 5471 filings, makes the retroactive high-tax exclusion election for each covered year to eliminate the GILTI inclusion, and brings the client into annual compliance with a going-forward program that prevents the same gap from rrecurring Moreover, the $ 10,000-per-form-per-year minimum penalty for Form 5471 non-filing makes the streamlined correction — with its 5% penalty on the FBAR balance — a cost-effective solution even for long-standing company owners with many years of missed returns.
The three most important actions for any UK-resident US citizen who owns a UK limited company are: first, confirm that Form 5471 is required and has not been filed — it is required for virtually every US person who owns 10% or more of a UK company; second, assess the GILTI high-tax exclusion election for all covered years using the company's effective UK corporation tax rate; and third, initiate the streamlined procedures immediately to resolve the missed filings before the IRS identifies the UK company through FATCA data or Companies House information exchange.

FAQs
Q: What is GILTI, and does it apply to UK company owners?
GILTI is a US tax charge under IRC Section 951A on a US shareholder's pro rata share of a UK company's net tested income, accruing annually regardless of whether dividends are paid. It applies to any US citizen owning more than 50% of a UK company — a controlled foreign corporation.
Q: What is the GILTI high-tax exclusion and how does it help UK companies?
The high-tax exclusion election entirely removes income subject to a foreign effective rate above 18.9% from the GILTI calculation. Since the UK's main corporation tax rate is 25%, most UK trading companies qualify, eliminating the GILTI inclusion and resulting in zero additional US tax on UK company profits.
Q: Does IRS streamlined filing compliance cover missed Form 5471 returns?
Yes. The streamlined foreign offshore procedures correct non-wilful failures to file Form 5471 for each covered year, alongside the personal income tax returns and FBARs. The retroactive GILTI high-tax exclusion election can be made on the corrected Form 8992 attached to each year's return.
Q: What is the penalty for not filing Form 5471?
The minimum penalty is $10,000 per Form 5471 per year, rising to $50,000 after IRS notification. The penalty applies even where no US tax is owed. The streamlined procedures address the covered three-year period; a non-wilfulness narrative addresses the broader exposure for earlier years.
Q: What is the Section 962 election, and is it better than the high-tax exclusion?
The Section 962 election taxes GILTI at the 21% corporate rate with an indirect foreign tax credit, rather than excluding it. For UK companies at 25%, the high-tax exclusion is strictly better — producing zero US tax. Section 962 is more useful where the effective UK rate is below 18.9%.
Q: Must a UK company's bank account be on the FBAR?
Yes, where the US-citizen director has a financial interest in or signature authority over the account. A sole director-shareholder of a UK company has both. The account must be included in the annual FBAR where its balance exceeds $10,000 at any point and in the streamlined six-year FBAR package.
