Can a family office finance director sign Form 14653 on the principal's behalf?

No. Form 14653 is the individual taxpayer's own certification that their failure to file was non-wilful, and the IRS requires the original signed certification with the submission. Office staff can supply the chronology and documents that support the narrative, but only the principal can attest to what they personally knew and why filings were missed. Each US family member signs a separate certification.

Does a US citizen principal living in the UK have to report accounts owned by a UK holding company on an FBAR?

Yes, where the principal owns more than 50 percent of the company. Under 31 CFR 1010.350 a US person has a financial interest in an account whose owner of record is a corporation in which they own, directly or indirectly, more than 50 percent of the voting power or total value of the shares. The same applies to partnerships by reference to profits or capital.

Do US-citizen staff of a UK family office need to file their own FBAR?

Usually yes, if they are signatories. A US person with signature or other authority over foreign financial accounts whose combined value exceeded $10,000 at any time in the calendar year must file an FBAR, even with no ownership. The regulatory exceptions for employees cover specific regulated and listed entities, which a privately owned UK family office does not obviously fall within.

If the principal is UK resident, do all family members use the same streamlined procedure?

No. The non-residency requirement is tested for each person separately. A US citizen or green-card holder must have had no US abode and been physically outside the United States for at least 330 full days in one or more of the most recent three years. A relative living in the United States fails that test regardless of where the principal lives, and UK residence is a separate UK question.

Why can UK consolidated family office accounts not be used directly for US returns?

Because US reporting is per taxpayer, per entity and per calendar year. Consolidated accounts are in sterling, follow UK accounting year ends or the UK tax year running 6 April to 5 April, and eliminate the inter-company shareholdings and balances that Forms 5471 and 8865 ask about. The preparer works from entity-level ledgers, re-cuts them to calendar years and allocates each item to the correct individual.

IRS Streamlined Filing Experts for Family Office Principals

Q: Is there a penalty under the Streamlined Foreign Offshore Procedures?

No. A taxpayer who meets the non-residency requirement and makes a compliant submission pays the tax and statutory interest due but is not subject to failure-to-file, failure-to-pay, accuracy-related, information return or FBAR penalties. The 5% miscellaneous offshore penalty belongs to the Streamlined Domestic Offshore Procedures, which apply to people who do not meet the non-residency requirement.

IRS Streamlined Filing Experts are tax preparers who assemble the full Streamlined Filing Compliance Procedures package for a US citizen or green-card holder who has missed US returns, FBARs and information returns through non-wilful conduct. For the principal of a UK single-family office, that package is three years of income tax returns with every required information return, six years of FBARs, and a personal non-wilful certification, and it is built from records the office already holds. The preparer does the US technical work; the office staff supply the data; the principal alone signs.

That division of labour sounds simple, and in the family-office engagements we prepare it is the part that most often goes wrong. The office is organised around the family as a single economic unit, with consolidated reporting across holding companies, investment companies, partnerships and directly held accounts. The IRS is organised around the individual taxpayer. Every US person in the family is a separate filer with a separate residency test, a separate certification and separate exposure. This article sets out how the work is actually split, what gets scoped, and what the office cannot do on the principal's behalf.

What do IRS Streamlined Filing Experts do for a family office principal?

A streamlined filing preparer converts the office's records into a complete, internally consistent US submission. The Streamlined Filing Compliance Procedures are an IRS route for taxpayers whose failure to report foreign financial assets and pay the related tax was non-wilful, which the IRS describes as conduct due to negligence, inadvertence, mistake or a good-faith misunderstanding of the law. The foreign version is set out at https://www.irs.gov/individuals/international-taxpayers/u-s-taxpayers-residing-outside-the-united-states and the domestic version at https://www.irs.gov/individuals/international-taxpayers/u-s-taxpayers-residing-in-the-united-states.

In a family-office setting the preparer's work falls into five jobs: mapping the ownership structure to identify every US filer and every reportable entity; scoping the accounts each filer must report; preparing the returns, information returns and FBARs from source records; drafting the factual narrative for each person's certification from that person's own account of events; and setting up a repeatable annual process so the problem does not return. This is preparation and compliance work, not a restructuring exercise.

Which streamlined route applies to each family member?

The route is decided person by person, never for the family as a whole. Under the Streamlined Foreign Offshore Procedures, a US citizen or green-card holder meets the non-residency requirement if, in any one or more of the most recent three years for which the return due date has passed, they had no US abode and were physically outside the United States for at least 330 full days. Where a married couple files jointly, the IRS page states that both spouses must meet the requirement.

The consequences of that test are significant. A person who qualifies for the foreign procedures files delinquent or amended returns for the most recent three years, files delinquent FBARs for the most recent six years, pays the tax and statutory interest due, and is not subject to failure-to-file, failure-to-pay, accuracy-related, information return or FBAR penalties on a compliant submission. There is no offshore penalty under the foreign procedures. A person who fails the non-residency test falls under the Streamlined Domestic Offshore Procedures, which carry a miscellaneous offshore penalty of 5% of the highest aggregate year-end balance or value of the foreign financial assets subject to the penalty across the covered years. The domestic route also requires that the person has previously filed a US return, where required, for each of the most recent three years, so it works through amended returns only.

Family offices routinely serve relatives in different positions. A principal who has lived in London for decades will usually pass the 330-day test; an adult child studying or working in the United States will not; a family member who divides the year between homes needs a day count from travel records before anyone assumes an answer. The office's travel records are usually the best evidence available. UK residence is a separate question again: GOV.UK explains at https://www.gov.uk/tax-foreign-income/residence that UK residence usually turns on days spent in the UK in the tax year, and being UK resident does not by itself establish the US non-residency requirement.

Who gathers what: the office staff or the preparer?

The office gathers facts and documents; the preparer makes every US classification and reporting decision. Staff should not be asked to decide whether an entity is a controlled foreign corporation or whether an account is reportable, and the preparer should not be reconstructing bank balances the finance team can export in minutes. The split we use in practice is below.

Finance director or controller: entity ownership chart with percentages and dates of change, statutory accounts and trial balances for each company and partnership, share registers, partnership agreements and capital account statements.
Treasury or bookkeeping team: a schedule of every financial account in the structure, the legal owner of each, account numbers, institution names and addresses, and the maximum balance for each calendar year under review.
Investment team or custodian liaison: portfolio valuations at each 31 December, transaction histories, income and distribution statements, and fund-level detail for each pooled investment held.
Operations or the private office: bank mandates and signatory lists for every account, travel records and day counts for each US family member, and copies of passports and US immigration documents.
UK accountants to the family: UK Self Assessment returns and computations for each US person, and UK corporation tax computations for each company, so that UK tax paid can be matched to the right US year.
The preparer: US entity classification, filer identification, FBAR and information return scoping, currency conversion on a consistent documented basis, return preparation, and the reconciliation of every figure back to the office's source records.
The principal and each US family member personally: the factual account of why filings were missed, review of the returns, and signature.

How are accounts held through holding and investment companies scoped for FBAR?

An FBAR is required when a US person has a financial interest in, or signature or other authority over, foreign financial accounts whose combined value exceeded $10,000 at any time in the calendar year, as the IRS summarises at https://www.irs.gov/businesses/small-businesses-self-employed/report-of-foreign-bank-and-financial-accounts-fbar. The point that family offices miss is that a company's accounts can be the principal's accounts for FBAR purposes even though the principal is not the account holder.

The regulation at 31 CFR 1010.350, which can be read at https://www.law.cornell.edu/cfr/text/31/1010.350, treats a US person as having a financial interest in an account where the owner of record is a corporation in which that person owns, directly or indirectly, more than 50 percent of the voting power or the total value of the shares, or a partnership in which that person owns more than 50 percent of the interest in profits or capital. The words directly or indirectly matter. Where a top holding company owns an investment company that owns a property-holding company, the test is traced down each tier, and every bank, custody and brokerage account in a majority-owned entity can land on the principal's personal FBAR.

Scoping therefore starts with the ownership chart rather than with a list of the principal's personal accounts. We build an account register covering every entity, then test each US person against each account on three questions: is this person the owner of record, does this person own more than 50 percent of the entity that is the owner of record, and can this person instruct the institution? Ownership percentages are tested for each year separately, because share reorganisations and capital contributions move people across the line. A family member holding a minority stake has no financial interest through ownership alone, though signature authority can still bring the same account onto their FBAR.

Do family office staff with signing authority have their own FBAR duty?

Yes, where the staff member is a US person. Signature or other authority is defined in the regulation as the authority of an individual, alone or in conjunction with another, to control the disposition of money or other assets in the account by direct communication with the institution. A US-citizen finance director, a green-card-holding treasury manager or a US-born personal assistant who sits on a bank mandate can therefore have a personal FBAR obligation for accounts in which they own nothing.

The regulation does provide exceptions for officers and employees with no financial interest in the account, but they are written for particular kinds of employer: banks examined by the US federal banking regulators, financial institutions registered with and examined by the US securities or commodities regulators, and entities with equity securities listed on a US national exchange or registered under the relevant US securities legislation. A privately owned UK family office does not obviously fall into any of those groups, so we treat each US-person signatory as a filer unless a specific exception is shown to apply.

The staff member's FBAR is their own filing, kept separate from the principal's engagement, and a late FBAR is filed through FinCEN's BSA E-Filing System with a reason for late filing.

Which information returns does a family office structure usually trigger?

Information returns are where a family-office submission differs most from an ordinary expatriate one. The streamlined procedures require the delinquent or amended income tax returns to be filed together with all required information returns for the three-year period. In a typical UK structure four forms do most of the work.

Form 5471, for US persons who are officers, directors or shareholders in certain foreign corporations. The IRS instructions at https://www.irs.gov/instructions/i5471 set out the filer categories, including a US person who controls a foreign corporation by owning more than 50% of its voting power or value, and a US shareholder owning 10% or more of a controlled foreign corporation. The form is attached to the income tax return, and the instructions state a penalty of $10,000 for each annual accounting period of each foreign corporation for failure to furnish the information.
Form 8865, the equivalent return for US persons with interests in certain foreign partnerships. UK limited partnerships and LLPs used for property or private investment are the usual subjects, and the category depends on the size of the interest and on contributions and changes during the year.
Form 8621, the shareholder return for passive foreign investment companies. Non-US pooled funds held in a portfolio are the common source, and the form is generally prepared fund by fund, which is why fund-level statements from the custodian are requested early.
Form 8938, the statement of specified foreign financial assets attached to the income tax return. The IRS comparison at https://www.irs.gov/businesses/comparison-of-form-8938-and-fbar-requirements gives the thresholds for a taxpayer living abroad who is unmarried or filing separately as more than $200,000 on the last day of the tax year or more than $300,000 at any time in it, and confirms that foreign shares not held in a financial account and foreign partnership interests are reportable on Form 8938 although they are not reportable on the FBAR.

Two features of these forms shape the engagement. Ownership is measured with attribution rules, so a family member with a small direct holding can become a filer because of shares held by relatives or through other entities; the Form 5471 instructions also contain exceptions for some people who are filers only through constructive ownership, and allow one person to file for others with the same or a greater filing requirement, with supporting statements. And signature authority works differently here than on the FBAR: the IRS comparison states that an account over which a person has only signature authority is not reported on Form 8938 unless the person otherwise has an interest in it. The same account can therefore be on a staff member's FBAR and on nobody's Form 8938 except the owner's.

Why can nobody in the office sign the non-wilful certification for the principal?

The certification is the principal's own statement of the principal's own conduct. A person using the foreign procedures completes Form 14653, Certification by U.S. Person Residing Outside of the U.S.; a person using the domestic procedures completes Form 14654, Certification by U.S. Person Residing in the U.S. The IRS requires the original signed certification to be submitted, with copies attached to each tax return and information return in the package.

Principals of family offices are used to delegating signature. Staff hold bank mandates, directors sign accounts, and the private office handles correspondence. None of that carries over. The certification explains why this individual did not file, what they knew, who they relied on and when they found out, and only that individual can attest to those facts. A finance director cannot certify the principal's state of mind, and an authorisation given to a tax representative does not change who makes the statement.

What the office can properly do is supply the chronology. Staff can show when accounts were opened, which professional firms were instructed and on what scope, what the engagement letters said about US tax, and when the issue was first raised. We interview the principal directly, draft the narrative from that conversation, and check it against the office's documents. Each US family member gets their own interview and their own narrative; a statement copied across siblings with the names changed is the failure mode we see most often in packages prepared in-house.

How does consolidated family office reporting become per-taxpayer US returns?

Consolidated reporting is the office's management view; a US return is one person's legal view, and the two differ in at least four ways. The first is the reporting period: GOV.UK confirms the UK tax year runs from 6 April to 5 April, companies in the structure have their own accounting year ends, and US individual returns and FBARs run on the calendar year. The second is currency, since the office reports in sterling and US forms are completed in US dollars. The third is ownership, because consolidation eliminates the inter-company balances and shareholdings that the information returns specifically ask about. The fourth is attribution: a consolidated report shows what the family owns, while a return shows what this taxpayer owns directly, indirectly and constructively.

The preparer's job is to de-consolidate. We ask for entity-level ledgers rather than the consolidated pack, re-cut income and balances to calendar years, convert on a consistent and documented exchange-rate basis, and then allocate each item to the correct individual. The working papers reconcile back to the office's own numbers. This matters for more than accuracy. Where two siblings both report an interest in the same company, the entity information on their returns must agree, and the easiest way to guarantee that is a single master schedule for each entity from which every individual's forms are produced.

How are confidentiality, Form 2848 and Form 8821 handled inside the office?

Access is set on a need-to-know basis and written down at the start. A streamlined submission contains material that most office staff have never seen and should not see: each family member's personal narrative, their individual income, and sometimes facts one relative has not shared with another. Our working arrangement is that entity data flows through a single nominated office contact, usually the finance director, while personal narratives, draft certifications and individual returns go directly between the preparer and the individual concerned unless that individual instructs otherwise in writing.

The IRS authorisations follow the same logic. Form 2848, Power of Attorney and Declaration of Representative, authorises a named individual to represent the taxpayer before the IRS and to receive and inspect their confidential tax information; the IRS states at https://www.irs.gov/forms-pubs/about-form-2848 that the representative must be a person eligible to practice before the IRS. Office staff are generally not in that category. Form 8821, Tax Information Authorization, is the related form the IRS lists alongside it, and it is the one to consider where the principal wants a named person to be able to see IRS information without acting as representative. Each adult family member signs their own authorisations. A parent's form does not cover an adult child, and the office should not assume that it holds authority over one relative's IRS correspondence because it holds it for another.

What does a family office streamlined submission look like in practice?

The following is an illustration with invented facts and figures, not a client case. A US-born principal has lived in London for over twenty years and has never filed a US return. The single-family office manages a UK holding company owned 60% by the principal, 15% by the principal's non-US spouse, 15% by an adult daughter who holds a green card and lives and works in New York, and 10% by an adult son who is a US citizen living in the UK. The holding company wholly owns a UK investment company. The principal also holds 55% of the capital of a UK property partnership and has personal bank and portfolio accounts. The office's US-citizen finance director is a signatory on every company account.

Assume, purely for illustration, that the companies' accounts held a combined maximum of £4,000,000 in the latest year and that a rate of $1.30 to £1 is used as an assumed conversion, giving about $5,200,000. The principal owns more than 50 percent of the holding company and, indirectly, of the investment company beneath it, so those company accounts go on the principal's FBARs for six years alongside the personal accounts and the partnership's accounts. The principal passes the 330-day test and uses the foreign procedures: three years of returns with Forms 5471 for both companies, Form 8865 for the partnership, Forms 8621 for any non-US funds in the personal portfolio, Form 8938, and Form 14653. Tax and interest are paid; no penalty applies.

The son also passes the 330-day test and makes his own submission under the foreign procedures with his own Form 14653. His 10% holding does not give him a financial interest in the company accounts, but it needs testing against the Form 5471 categories with family attribution taken into account. The daughter fails the non-residency requirement because she lives in the United States. If she has filed US returns for the last three years that left out her shareholding, her route is the domestic procedures with amended returns, Form 14654 and the 5% miscellaneous offshore penalty computed on the assets within its base. The finance director owns nothing but has signature authority, so she has her own FBARs to file, outside the family's engagement.

What is the timetable, and what does ongoing annual compliance involve?

The timetable is driven by data gathering, not by drafting. The IRS does not publish a processing time for streamlined submissions that we would quote, and the stages within the office's control run in a predictable order: structure mapping and filer identification; the account register and mandate review; calendar-year data extraction; return and information return preparation; narrative interviews and certification drafting; principal review; and filing. Returns under the foreign procedures are submitted on paper to the IRS address given for the procedure, marked as the IRS page directs, and FBARs are filed electronically through the BSA E-Filing System, selecting Other as the reason for late filing and entering Streamlined Filing Compliance Procedures in the explanation. Current-year filings do not wait: the FBAR is due on 15 April with an automatic extension to 15 October, and the latest year's return is prepared alongside the catch-up years so the family comes out fully current.

After the submission, compliance becomes an annual cycle that the office can run with very little friction if it is designed properly. We leave the office with a calendar-year close for US purposes, an account register updated whenever an account is opened or closed or a mandate changes, a standing rule that any change in shareholdings or partnership capital is notified before it happens, and a new-joiner question for staff about US citizenship or green-card status. FBAR records are kept for five years from the FBAR due date, which is the retention period the IRS states. The protection the streamlined procedures give covers the years in the submission; it does nothing for a later year that is filed late, which is why the annual process matters as much as the catch-up.
