IRS Streamlined Filing: Non-Dom Business Owner Guide

IRS Streamlined Filing for Non-Dom UK Business Owners

The IRS streamlined filing process for non-domiciled US citizens who own UK limited companies presents a combination of compliance gaps and planning considerations that is unique in cross-border tax — because the FIG regime that exempts overseas income from UK tax during the first four years of residence creates an interaction with the US compliance obligations that most non-dom business owners have not previously considered. The typical non-dom US citizen who arrives in the UK, incorporates a UK trading company, and relies on a UK accountant for the corporation tax return has the same prior-year Form 5471 gap as any other UK company owner — but with the additional layer of the FIG regime affecting the character of the income that flows through the corrected returns. Furthermore, the FIG regime during the covered years may have exempted certain overseas income streams from UK tax — meaning those income streams carried no UK income tax credit on the amended returns, and the US income tax applies in full. Additionally, the wilfulness assessment for a non-dom US citizen who has recently arrived in the UK is typically straightforward — a new arrival from a non-English-speaking country, relying entirely on a UK accountant with no US tax knowledge, is one of the clearest non-wilful scenarios in the programme. Consequently, the IRS streamlined filing engagement for a non-dom UK business owner addresses the Form 5471 correction, the FIG regime interaction on the amended returns, the FBAR for the company account, and the non-wilfulness narrative — as a coordinated submission that establishes the clean compliance history from which the correct annual framework operates going forward.

The Form 5471 Gap for Non-Dom Business Owners

Why the Gap Arises for New UK Arrivals

Non-domiciled US citizens who arrive in the UK from countries where the US tax obligations were not prominently discussed — including Germany, France, Australia, Canada, and many others — typically have no awareness of Form 5471 when they incorporate their UK company. Furthermore, the UK accountant who registers the company at Companies House, prepares the corporation tax return, and files the UK self-assessment has no US tax training and no professional obligation to flag the US international information return requirements. Additionally, the FIG regime — where available — means the non-dom business owner may pay very little UK income tax in the first four years, removing one of the most common triggers that prompts newly UK-resident Americans to seek US tax advice. Consequently, the Form 5471 gap for a non-dom UK company owner typically spans from the date of incorporation to the date the client first engages IRS streamlined filing — often two to four years for a recent arrival, sometimes longer. The IRS Form 5471 guidance is at https://www.irs.gov/forms-pubs/about-form-5471.

The Penalty Exposure Without Correction

The penalty for failure to file Form 5471 is $10,000 per year per company — applying equally to profitable years, loss years, and years where the GILTI high-tax exclusion would have eliminated any income inclusion. Furthermore, the statute of limitations on the Form 1040 does not begin running for any year in which Form 5471 was required but not filed — meaning all prior years remain permanently open for IRS examination. Additionally, a non-dom business owner who has owned their UK company for three years and never filed Form 5471 faces a maximum penalty exposure of $30,000 — reduced to the 5% streamlined penalty where the correction is completed through the IRS streamlined filing foreign offshore procedures. Consequently, the IRS streamlined filing submission provides the most cost-effective correction route for a non-dom business owner with a Form 5471 gap — replacing the $10,000 per year standard penalty with the predictable 5% miscellaneous offshore penalty on the highest aggregate FBAR balance. The IRS streamlined guidance is at https://www.irs.gov/individuals/international-taxpayers/streamlined-filing-compliance-procedures.

The FIG Regime on the Amended Returns

FIG-Exempt Income on the Corrected Returns

Where the non-dom business owner was within the FIG qualifying period during the covered return years — having not been UK-resident in any of the ten preceding years — the corrected Form 1040 for each covered year must reflect the FIG election where it was beneficial. Furthermore, the FIG election exempts overseas income from UK income tax — meaning overseas investment income, overseas rental income, and overseas employment income during the FIG period carries no UK income tax credit on the amended returns. Additionally, where the IRS streamlined filing correction covers years in which the client had significant overseas income streams alongside the UK company income, the corrected returns must model the FIG election decision for each year — confirming whether the FIG exemption produced a better combined outcome than the standard UK resident position. Consequently, the amended return preparation for a non-dom business owner is more complex than for a standard UK-resident American — since the FIG election must be assessed for each covered year as part of the IRS streamlined filing preparation. The HMRC FIG guidance is at https://www.gov.uk/government/publications/changes-to-the-taxation-of-non-uk-domiciled-individuals.

UK Company Income Is Never FIG-Exempt

A critical point in the non-dom IRS streamlined filing analysis is that the UK company's profits — and the salary and dividends extracted from it — are not FIG-exempt. Furthermore, salary from a UK company is UK-source employment income — subject to UK income tax regardless of the FIG regime or the shareholder's non-dom status. Additionally, dividends from a UK company are UK-source income — subject to UK dividend tax above the annual allowance regardless of the FIG election. Consequently, the corrected returns for a non-dom business owner separate the UK company income streams — which carry UK income tax credits available for Form 1116 — from any FIG-exempt overseas income streams — which carry no UK income tax credit and produce full US income tax with no offset. The IRS Form 1116 guidance is at https://www.irs.gov/forms-pubs/about-form-1116.

The FBAR for Non-Dom Business Owners

Company and Personal Accounts From Year One

The FBAR obligation for a non-dom US citizen begins from the first calendar year in which UK foreign financial accounts are opened — from the date of first UK bank account opening in the year of arrival. Furthermore, the company current account — where the US citizen owns more than 50% of the UK company — is FBAR-reportable from the date of incorporation. Additionally, the non-dom status and FIG regime have no effect on the FBAR obligation — the FBAR covers all foreign financial accounts regardless of the UK tax treatment of the income those accounts generate. Consequently, the IRS streamlined filing correction for a non-dom business owner must include six years of FBARs listing both the personal accounts and the company account — with the company account at its highest balance during each covered calendar year confirmed from the full-year bank statements. The FinCEN FBAR guidance is at https://www.fincen.gov/financial-crimes-enforcement-network/fbar.

Calculating the 5% Penalty With the Company Account

The 5% miscellaneous offshore penalty is calculated on the highest aggregate balance of all FBAR-reportable accounts across all six covered years — including the company current account alongside all personal accounts, pensions, and ISAs. Furthermore, the company account frequently holds the largest single balance in the entire FBAR aggregate — working capital and retained profits can produce a company account balance that significantly exceeds the combined personal account balances. Additionally, the highest aggregate year across the six covered years is the year in which the combined balance of all accounts was greatest — not necessarily the most recent year. Consequently, IRS streamlined filing calculates the 5% penalty amount precisely for each non-dom business owner client — including the company account balance in every covered year — before the submission begins, so the client understands the exact penalty cost before any work is committed.

The Non-Wilfulness Assessment for New UK Arrivals

Why New Arrivals Have Strong Non-Wilfulness Cases

Non-domiciled US citizens who have recently arrived in the UK from a non-English-speaking country — or from any country where US international information returns were not part of their professional experience — present the strongest possible non-wilfulness cases in the IRS streamlined filing programme. Furthermore, the non-wilfulness narrative for a French or German national who became a US citizen through naturalisation, moved to the UK for business, incorporated a UK company, and relied entirely on a UK accountant with no US tax training is factually compelling — the advisory chain clearly explains why the US obligations were unknown. Additionally, the absence of any IRS contact during the non-compliance period, the voluntary nature of the correction, and the consistent use of UK advisers throughout the non-compliance period all strengthen the non-wilfulness position. Consequently, the Form 14653 non-wilfulness certification for a recently arrived non-dom business owner is typically one of the most straightforward narratives to prepare — addressing the home country background, the UK advisory chain, and the genuine lack of any awareness of US international information return requirements.

The Elevated Risk Factors to Watch

Even for non-dom business owners with otherwise strong non-wilfulness positions, certain facts can elevate the wilfulness risk and must be addressed in the Form 14653 narrative. Furthermore, the most significant risk factors are: any prior contact with a US tax adviser — even for a different purpose such as the sale of US property; any awareness of the FBAR through a bank letter or account opening form; and a period of employment by a US company that provided any US tax guidance. Additionally, where the non-dom business owner is a naturalised US citizen who previously lived in the United States and filed US returns before moving abroad, the IRS will expect greater awareness of US obligations than for a foreign-born dual national who obtained US citizenship through other means. Consequently, IRS streamlined filing conduct the wilfulness assessment for every non-dom business owner client as a specific and fact-sensitive exercise — not assuming strong non-wilfulness simply because the client recently arrived in the UK.

The GILTI Analysis on the Corrected Returns

GILTI for FIG-Period Years

The GILTI high-tax exclusion analysis on the corrected Form 5471 for the covered years is performed in exactly the same way as for a non-FIG UK company owner — the effective UK corporation tax rate on tested income is compared to the 18.9% threshold, and the election is made where the rate exceeds the threshold. Furthermore, the FIG regime does not affect the GILTI analysis — the company's corporation tax rate is determined by the company's profits and the UK tax regime, not by the shareholder's FIG status. Additionally, where the UK company paid 25% corporation tax on its trading profits during the covered years, the GILTI high-tax exclusion election is available for those years — eliminating the GILTI income inclusion on the corrected returns. Consequently, the corrected Form 5471 for each covered year includes the GILTI effective rate calculation and the high-tax exclusion election where applicable — and the corrected Form 1040 for each covered year reports zero GILTI inclusion where the election was available. The IRS GILTI guidance is at https://www.irs.gov/businesses/corporations/gilti-high-tax-exclusion.

Case Study: Non-Dom US Citizen, UK Tech Company, Three-Year Gap

Our team completed a IRS streamlined filing submission for a US citizen who had arrived in the UK from France three years earlier — a naturalised US citizen of French origin who had lived in the United States for six years before moving to London for a UK technology venture. Furthermore, she had incorporated a UK limited company in year one of UK residence — with a French accountant managing her personal affairs and a UK accountant managing the company corporation tax. Neither adviser had mentioned Form 5471, the FBAR, or any other US international information return. Additionally, she had a workplace DC pension from a prior UK employment worth approximately £38,000, a personal Lloyds current account with a highest annual balance of approximately £22,000, and the company current account with a highest annual balance of approximately £86,000 in year two.

The IRS streamlined filing wilfulness assessment confirmed: no prior US tax adviser contact, no US employer with US tax guidance, FBAR awareness assessment — the Lloyds account opening form mentioned US person status but the bank letter was generic and did not specifically explain the FBAR. The wilfulness risk was assessed as low — non-wilfulness certification supported. Furthermore, the 5% penalty was calculated on the highest aggregate FBAR balance across the six covered years (three personal years and three company years). The highest aggregate — year two — was approximately £146,000 ($185,420 at the Treasury rate): company account £86,000, personal account £22,000, pension £38,000. The 5% penalty was $9,271. Additionally, the corrected returns for years one through three included Form 5471 for the company — GILTI high-tax exclusion elected in all three years at 25% effective rate — salary on Form 1040 with zero UK income tax (below personal allowance), dividends on Schedule B with Form 1116 passive basket credit. FIG election assessed: client had overseas investment income of approximately $18,000 per year — FIG election modelled and confirmed as beneficial in all three covered years. Consequently, the complete IRS streamlined filing submission was completed in eleven weeks — with the 5% penalty of $9,271 replacing the maximum standard Form 5471 penalty of $30,000.

Common Non-Dom Streamlined Mistakes

Not Including the Company Account in the FBAR

The most common FBAR error in non-dom business owner cases is preparing the six FBARs without the company current account — listing only the personal accounts and pension. Furthermore, the majority-owned entity rule requires the company account to be included where the US citizen owns more than 50% of the company. The correct approach requires IRS streamlined filing to specifically identify the company account and include it at its highest annual balance in every covered FBAR year — using the full-year monthly statements rather than the year-end accounting balance.

Not Assessing the FIG Election on the Amended Returns

Preparing the corrected Form 1040 for each covered year without assessing the FIG election decision means the amended returns may not reflect the optimal UK tax position — potentially overstating the UK income tax credit where FIG was beneficial and understating the US income tax where FIG-exempt overseas income was not reported. Furthermore, the FIG election assessment must be performed for each covered year individually. The correct approach requires IRS streamlined filing to model the FIG election for each covered year as part of the amended return preparation — confirming the optimal position for the specific income mix in that year.

Assuming Strong Non-Wilfulness Without Assessment

Not every non-dom business owner presents a strong non-wilfulness case — the specific facts of each client's background, prior US tax contact, and awareness indicators must be assessed individually. Furthermore, a non-dom business owner who previously employed a US CPA for personal US tax matters presents a materially different wilfulness risk than one who has never had any US tax adviser contact. The correct approach requires IRS streamlined filing to conduct a written, fact-specific wilfulness assessment for every non-dom business owner client — not assuming non-wilfulness from the non-dom status alone.

Conclusion

The IRS streamlined filing process for non-domiciled US citizen UK company owners combines the standard Form 5471 correction with the additional complexity of the FIG regime interaction on the amended returns — distinguishing UK company income (UK income tax creditable on Form 1116) from FIG-exempt overseas income (no UK income tax credit, full US income tax). Furthermore, the FBAR correction must include the company account alongside all personal accounts — and the company account frequently drives the 5% penalty calculation as the largest single FBAR balance. Moreover, the non-wilfulness narrative for a recently arrived non-dom with no prior US tax adviser contact is typically one of the strongest available — but must be confirmed from the specific facts of each client's background rather than assumed from the non-dom status alone.

FAQs

Q: Does the FIG regime affect the Form 5471 filing obligation?

A: No. Form 5471 remains mandatory for every year the non-dom US citizen owns 10% or more of a UK company — regardless of FIG status. The FIG regime affects the UK tax treatment of overseas income but has no effect on the US international information return obligations. Form 5471 is required from the first year of company ownership.

Q: Are UK company dividends FIG-exempt on the corrected returns?

A: No. UK company dividends are UK-source income — not foreign income — and are therefore not covered by the FIG exemption. UK dividend tax applies to dividends above the annual allowance regardless of the shareholder's FIG status. The FIG regime exempts overseas income only; dividends from a UK company are always subject to UK dividend tax.

Q: How does the FIG regime affect the 5% streamlined penalty?

A: It does not affect the penalty calculation. The 5% miscellaneous offshore penalty is calculated on the highest aggregate balance of all FBAR-reportable accounts — including the company account — across the six covered years. The FIG regime has no effect on the FBAR aggregate or the penalty base.

Q: Why do non-dom business owners have strong non-wilfulness cases?

A: Because the combination of a non-English-speaking home country background, exclusive reliance on UK and home-country advisers with no US tax knowledge, no prior IRS contact, and a voluntary correction creates the clearest possible factual basis for non-wilfulness. The Form 14653 narrative for these clients addresses the full advisory chain and the absence of any US tax awareness indicators.

Q: Must the company account be included in the FBARs for the covered years?

A: Yes. Where the US citizen owns more than 50% of the UK company, all company bank accounts are FBAR-reportable under the majority-owned entity rule. The six corrected FBARs must include the company account at its highest annual balance in each covered year — confirmed from the full-year monthly bank statements, not the year-end accounting balance.

Q: Is the GILTI high-tax exclusion available during the FIG period?

A: Yes. The GILTI analysis is entirely independent of the FIG regime. Where the company paid UK corporation tax at 25% during the covered years, the effective rate exceeds the 18.9% GILTI threshold and the high-tax exclusion election is available on Form 5471 for those years — exactly as for a non-FIG UK company owner.
