Do I need to file Form 5471 for my UK company inside a Streamlined submission?

Almost certainly. Form 5471 is required under sections 6038 and 6046 from certain US citizens and residents who are officers, directors or shareholders in certain foreign corporations, and a UK limited company is a foreign corporation. A Streamlined package must include the applicable information returns for the covered years, so a founder normally files one Form 5471 per company per year in the three-year window. Each form must be prepared to the filer category that applied in that specific year, which can change as the share register changes, and each must be annotated Streamlined Foreign Offshore in red like the returns it accompanies.

Does the Streamlined route fix company years before the three-year window?

No. The procedures cover three years of income tax returns and six years of FBARs, and the relief does not extend to earlier years. A founder whose UK company was incorporated well before that window has Form 5471 obligations for the earlier years that the submission does not resolve. That gap should be identified and quantified before the package is prepared, not discovered afterwards, and the certification narrative has to describe the full period of non-compliance honestly rather than stopping at the edge of the window.

Can I use the Delinquent FBAR Submission Procedures instead if I only missed FBARs?

No. The IRS withdrew its Delinquent FBAR Submission Procedures page and the address now returns a not-found response, so it should not be treated as an available route. The Delinquent International Information Return Submission Procedures page remains live for delinquent information returns, but the IRS warns on it that penalties may be assessed during processing without considering an attached reasonable cause statement. Any firm still presenting the delinquent FBAR route as a current option is working from outdated material.

Does travelling to the United States for fundraising break my Streamlined eligibility?

Not necessarily. The non-residency test asks whether, in one or more of the most recent three years for which the return due date has passed, you had no US abode and were physically outside the United States for at least 330 full days. Only one qualifying year is needed. A heavy US travel year can fail the day count while another year in the window still qualifies. The IRS also notes that temporary presence in the United States, or keeping a dwelling there, does not by itself mean your abode is in the United States. Day counts should be supported by travel records rather than estimated.

Can a Streamlined submission be filed electronically?

No, not the return package. The IRS states that the documents and payments must be sent in paper form and that electronic submissions will not be accepted, to the Austin service centre address given in its guidance, with Streamlined Foreign Offshore written in red at the top of the first page of each return and information return. The IRS describes that annotation as critical to processing. The FBARs are the exception and are filed electronically through the FinCEN BSA E-Filing System, giving Streamlined Filing Compliance Procedures as the reason for late filing.

IRS Streamlined Filing Experts London

IRS Streamlined Filing experts London founders turn to are specialists who prepare and certify a Streamlined Foreign Offshore Procedures submission for a US person living in the UK, and who can carry that founder's corporate reporting through the same package. For a US citizen who owns a UK limited company, the second half is the whole difference. A Streamlined package for a salaried employee is three tax returns, six FBARs and a certification. A Streamlined package for a founder is those same components plus Form 5471 for the UK company, a share history that has to reconcile to a public record, sterling figures translated on two different conventions, and a remuneration pattern built for HMRC that behaves badly on a US return.

What do IRS Streamlined Filing experts London founders hire actually prepare?

An IRS Streamlined Filing expert is a preparer who assembles, calculates and certifies the complete Streamlined Foreign Offshore Procedures package for a US person resident outside the United States. The role is narrower and more exacting than general expatriate tax preparation, because the submission is a single paper filing that either holds together or does not. There is no draft stage with the IRS, no negotiation and no correction cycle. Everything the IRS will ever see about why the filings were missed is in the envelope on the day it is posted.

For a London founder, the engagement normally has to cover the following work.

Eligibility testing before any preparation begins, covering the non-residency test on evidenced travel records and an honest read on non-willfulness.
Reconstruction of three years of US returns from UK payroll data, statutory company accounts and personal banking records held in sterling.
Six years of FBARs covering personal accounts and any company account over which the founder holds signature authority.
Form 5471 for the UK company for each year in the window, prepared to the filer category that actually applied in that year.
A Form 14653 certification narrative drafted from the same facts that appear in the returns and the company record.
Calculation of tax due and applicable statutory interest, then physical assembly, red annotation and posting of the package.

Is the Streamlined Foreign Offshore Procedure still open?

Yes. The Streamlined Foreign Offshore Procedures remain a live route. The IRS guidance page for US taxpayers residing outside the United States was live and carried a 2026 review date when this was written, and it contains no closing announcement. That contrasts with the Offshore Voluntary Disclosure Program, which the IRS states closed on 28 September 2018.

One neighbouring route has gone, and it matters when you are assessing a firm. The IRS withdrew its Delinquent FBAR Submission Procedures page, and the address now returns a not-found response. Anyone still describing that as a live option for a founder who filed returns but missed FBARs is working from stale material, which tells you how recently they have read the source rather than a summary of it. The Delinquent International Information Return Submission Procedures page is still live, but the IRS warns on it that penalties may be assessed during processing without considering an attached reasonable cause statement. That warning is the reason most founder cases with unfiled Forms 5471 belong inside a Streamlined submission rather than beside one.

Who is eligible for the Streamlined Foreign Offshore Procedures?

For a US citizen or lawful permanent resident, the IRS requires that in one or more of the most recent three years for which the return due date has passed, the individual did not have a US abode and was physically outside the United States for at least 330 full days. The IRS adds that neither temporary presence in the United States nor maintenance of a dwelling there necessarily means the individual's abode is in the United States, and points to Publication 54 for the meaning of abode. An individual who is neither a citizen nor a lawful permanent resident must instead show they did not meet the substantial presence test of section 7701(b)(3) in at least one of the most recent three years.

Founders fail this test more often than employees, and usually on day count rather than abode. Fundraising trips, US customer visits, accelerator programmes and board meetings accumulate quietly. A founder who spent four months in San Francisco raising a round has probably broken the 330 day count for that year. That does not end eligibility, because only one qualifying year in the window is needed, but it does mean the qualifying year must be located deliberately and evidenced with travel records rather than assumed.

Two further gates apply. The IRS states that the terms of the Streamlined Filing Compliance Procedures require a valid Taxpayer Identification Number, and that a taxpayer who is eligible for a Social Security number but submits without one is not eligible for the favourable penalty provisions. Separately, the route is closed to anyone already under IRS civil examination or criminal investigation for the years concerned.

What does non-willful mean when you have been running a company?

The IRS defines non-willful conduct as conduct that is due to negligence, inadvertence, or mistake, or conduct that is the result of a good faith misunderstanding of the requirements of the law. That definition works harder in a founder file than in an employee file, because a founder has taken deliberate structural decisions. Incorporating a company, allotting shares, setting a director's salary and declaring dividends are all conscious acts. None of them is evidence of willfulness in itself. But a certification narrative that quietly omits them reads as evasive, and omission is what turns a defensible file into a contested one.

The practical test is whether the narrative would survive being read side by side with the founder's own corporate records. If it would, it is a strong certification. If it depends on the reader not having those records, it is not.

What does a complete Streamlined submission actually contain?

Delinquent or amended returns for each of the most recent three years for which the return due date, or properly applied for extended due date, has passed.
Delinquent FBARs for each of the most recent six years for which the FBAR due date has passed, filed electronically through the FinCEN BSA E-Filing System with Streamlined Filing Compliance Procedures given as the reason for late filing.
A signed Form 14653 certification, with the original signed statement submitted and copies attached to each tax return and information return in the package.
Every applicable information return for those years, which for a founder usually means Form 5471, often Form 8938, and Form 8621 where non-US pooled funds are held.
Payment of all tax due as reflected on the returns, together with all applicable statutory interest on the late payment amounts.
The words Streamlined Foreign Offshore written in red at the top of the first page of each return and each information return.

The package goes in paper form to the IRS at 3651 South I-H 35, Stop 6063 AUSC, Attn: Streamlined Foreign Offshore, Austin, TX 78741. The IRS states that electronic submissions will not be accepted, and that the red annotation is critical to ensure the returns are processed through these special procedures. Where the submission qualifies, the IRS states the taxpayer will not be subject to failure-to-file and failure-to-pay penalties, accuracy-related penalties, information return penalties, or FBAR penalties. Penalties already assessed for those years are not abated. Tax and statutory interest are still payable in full.

On the FBAR side, the reporting trigger itself is unchanged by Streamlined status. FinCEN Form 114 is required where the aggregate value of foreign financial accounts exceeded 10,000 US dollars at any time during the calendar year reported. The FBAR is due 15 April following the calendar year reported, with an automatic extension to 15 October, and it is not filed with the federal tax return. Founders frequently under-count here, because a business account they can sign on is reportable to them personally even where they hold no beneficial interest in the funds.

Why does owning a UK company change the whole submission?

Form 5471 is the Information Return of US Persons With Respect To Certain Foreign Corporations, filed under sections 6038 and 6046 by certain US citizens and residents who are officers, directors or shareholders in certain foreign corporations. A UK limited company is a foreign corporation for this purpose. A US founder of one is almost always inside at least one filer category, and the form travels with the personal income tax return rather than being filed separately.

The exposure is what makes this the centre of gravity in a founder package. Outside Streamlined relief, the failure to file penalty under section 6038 starts at 10,000 US dollars per form per year, with further amounts where the failure continues after IRS notice. Three streamlined years for one UK company is three separate forms, each of which has to be genuinely complete rather than nominally present. A form filed with the required schedules left blank is not a filed form for these purposes, and a Streamlined submission that carries incomplete information returns is a submission with a hole in it.

Does your Form 5471 filer category change across the three years?

This is the point generic Streamlined pages miss, and it is where founder packages most often fail on inspection. The three Forms 5471 in a founder submission are frequently not the same form prepared three times. A company incorporated inside the window has no form at all for the year before incorporation. A founder who held the entire share capital in year one, took an angel or seed round in year two and was diluted in year three can sit in a different filer category in each year, because the categories turn on control and on ownership measured at defined points, not on how the founder describes their role.

The practical consequences are specific. The schedules required differ by filer category, so the three forms will not look alike. Share transactions have to be reported in the year they occurred, not in the year the founder noticed them. An option pool creates its own reporting question, because grants, lapses and exercises move the share position on particular dates. A preparer who rolls year one forward twice will produce a package that contradicts the founder's own register of members, and internal contradiction is precisely what invites an examiner to keep reading.

Does your Form 14653 narrative have to match Companies House?

In practice, yes, even though the IRS says nothing about UK filings. A UK founder is unusually exposed here because the company record is public. Companies House publishes the incorporation date, the register of members and share allotments, the annual accounts, confirmation statements and the register of people with significant control. Anyone, including a US examiner, can read the shape of the founder's UK business without asking the founder a single question.

So the certification narrative has to be checkable against that record. If the narrative says there was no meaningful trading until a particular year, the filed accounts should not show turnover before it. If it says no distributions were taken, the accounts should not show a dividend. The IRS asks for a narrative statement of facts giving specific reasons for the failure to report income, pay tax and submit required information returns, and the strongest version is one in which every date can be matched to a document the founder did not control the publication of. Salaried filers do not have this problem. Founders do, and handled properly it is an advantage rather than a risk, because a corroborated narrative is far more persuasive than an uncorroborated one.

How should sterling be translated across returns and FBARs?

Two different conventions operate inside the same package, and mixing them is a common source of internal inconsistency that a founder file cannot afford.

On the income tax returns, the IRS states it has no official exchange rate and generally accepts any posted exchange rate that is used consistently, with the general rule being to use the rate prevailing when the item is received, paid or accrued. The IRS also publishes yearly average rates, including sterling.
On the FBARs, FinCEN directs filers to convert the maximum value of each account into US dollars using the Treasury rate for the last day of the calendar year, and to use another verifiable rate with its source stated only where no Treasury rate exists.
On Form 5471, the figures originate in statutory accounts prepared in sterling, so the translation policy applied to the corporate schedules has to be stated and held constant across all three years.

This matters more for a founder than for a salaried filer because the same sterling amounts surface in several places. Director's remuneration feeds the return. The company accounts feed Form 5471. Personal and company account balances feed the FBARs. Consistency is a document control problem before it is a tax problem. The workable discipline is to fix one posted rate policy for the income tax side, document why it was chosen, apply it across all three years, and keep the FBAR conversions separate and explicitly year-end based so that a reviewer can see the difference is deliberate rather than careless.

What about company years that predate the three-year window?

Streamlined covers three return years and six FBAR years. A UK company incorporated eight years ago generated Form 5471 obligations for every year since incorporation, and Streamlined relief does not reach back to cover the earlier ones. This is the most under-discussed issue in founder cases, and it is not an edge case, because founders are precisely the cohort whose corporate reporting exposure predates the window that Streamlined offers.

There is no clean answer, and any firm that produces one quickly is not being straight with you. What a specialist should do is set out plainly what the window covers, what sits outside it, what the realistic assessment posture is for those earlier years, and how the certification narrative should describe a period that is not being filed. The narrative has to tell the whole story of the failure, and a story that stops at the edge of the window without acknowledging what came before is the flaw a reviewer notices first.

How does UK-efficient remuneration behave on a US return?

A low director's salary topped up with dividends is the standard UK owner-manager pattern, and it behaves badly inside a Streamlined package. The Foreign Earned Income Exclusion on Form 2555 applies to foreign earned income. A dividend from your own UK company is not earned income. A founder who assumed the exclusion covered everything they received frequently finds the dividend stream fully exposed once the returns are rebuilt, with relief depending instead on foreign tax credits and on how UK dividend tax interacts with the US passive category. That is often the single largest number in the whole submission, and it is one a generalist preparer can miss entirely by treating the founder as an ordinary expatriate employee.

Retained profit is the other founder-specific item. A US shareholder of a controlled foreign corporation can have an income inclusion under section 951A from the company's profits whether or not any distribution is made, so a founder who deliberately left profit in the UK company to fund growth can still have US income in the streamlined years. The rules applied must be the rules in force for each year filed, and the section 951A regime was amended by 2025 legislation for later tax years, so historic streamlined years and going-forward returns can sit under different versions of the same regime. Anyone preparing your package should be able to state which version they applied to which year without looking it up.

Employee equity adds a third layer. GOV.UK sets out the UK treatment of Enterprise Management Incentive options, under which options granted at market value and exercised within the statutory period can be acquired without an Income Tax or National Insurance charge, with Capital Gains Tax arising on sale, subject to limits including a cap of 250,000 pounds of options per employee over a three year period. Favourable UK treatment does not automatically carry across to the US side, and options granted by the founder's own company also move the share position that Form 5471 has to report.

A worked scenario: a London founder's Streamlined submission

Consider a US citizen who moved to London and incorporated a UK software company. She holds a UK current account, a UK savings account and a business account in the company name that she can sign on. She paid herself a small director's salary with dividends on top. She stopped filing US returns after her second year abroad, because a UK accountant told her the Foreign Earned Income Exclusion meant nothing was due. Across the three most recent qualifying years she raised an angel round in the second year and granted EMI options in the third, and she spent roughly a fifth of one year in the United States meeting investors.

The qualifying non-residency year is identified from actual travel evidence rather than assumed, because the fundraising year very likely fails the 330 day count and cannot be the year relied on.
Three years of returns are rebuilt with the dividend income treated as unearned, the exclusion applied only to the salary element, and foreign tax credits computed separately for the earned and passive categories.
Six years of FBARs cover both personal accounts and the company account she can sign on, with maximum values converted at the Treasury year-end rate for each year.
Three Forms 5471 are prepared to the filer category applicable in each year, reporting the share position as it actually stood, reflecting the angel round dilution and the option grants on their real dates.
The Form 14653 narrative names the advice she relied on, the point at which she learned it was wrong and what she did next, and it lines up with the incorporation date, allotment history and accounts already published at Companies House.
Tax and statutory interest are computed, the returns and information returns are annotated in red, and the whole package is posted to the Austin address as a single paper filing with proof of posting retained.

How should you assess IRS Streamlined Filing experts in London?

Credentials are the entry ticket rather than the answer. Only an attorney, a certified public accountant or an enrolled agent can represent you before the IRS if the file is later examined, so the person signing your returns should hold one of those. After that, what separates candidates is founder-specific and easy to test in a first conversation.

Ask how many Forms 5471 they prepare in a year, not how many Streamlined cases they have run, because the corporate side is where founder packages fail.
Ask what they will do about company years that predate the three-year window. A specialist has a considered position ready. A generalist changes the subject.
Ask which exchange rate policy they apply on the income tax side and how they handle the different FBAR convention.
Ask whether they draft the Form 14653 narrative themselves or send you a template to complete, because templates produce exactly the generic language the IRS finds least persuasive.
Ask what they check against Companies House before the narrative is finalised.
Ask whether they will tell you if you are not eligible. A firm that has never declined a Streamlined engagement is not testing eligibility.
Ask who assembles and posts the physical package, since paper filing and the red annotation are conditions of the procedure rather than formalities.

Fee structure matters less than scope. A fixed fee that quietly excludes Forms 5471, or that treats each information return as an extra, is not a fixed fee for a founder. Get the scope in writing before anything is prepared.

What happens after the package is posted?

The IRS states that returns submitted under these procedures are processed like any other return submitted to the IRS, that they will not be subject to IRS audit automatically, and that they may be selected for audit under existing audit selection processes. There is no closing agreement, no formal acceptance letter and no certificate of compliance. For most founders the visible outcome is a cashed payment and then silence, and the IRS publishes no service standard for how long that takes.

That absence of confirmation is exactly why the internal consistency of the package matters so much. Nothing is going to be tidied up by correspondence afterwards. Keep proof of posting, a complete copy of everything filed, the source records behind every sterling figure, the exchange rate policy you documented, and the travel evidence supporting the qualifying non-residency year. If questions arrive, they may arrive long after the working papers would otherwise have been archived, and the founder who can reproduce the file is in a materially different position from the one who cannot.

A Streamlined submission is one document set, filed once, that has to explain several years of a person's financial life and several years of a company's history at the same time. For a US founder in London that is a preparation problem with a corporate reporting problem inside it, and the two have to be solved by the same hands.
