Can one streamlined submission cover every US citizen in a family?

No. The Streamlined Filing Compliance Procedures are entered by each taxpayer individually, with the only combined submission being a married couple who file a joint return. Each adult child makes a separate submission with a separate certification and payment, and a minor child is a separate taxpayer too. A family can share documents, a timetable and a preparer, but not a certification.

Do both spouses have to qualify for the Streamlined Foreign Offshore Procedures?

Yes, where they file jointly. The IRS states that for joint return filers both spouses must meet the applicable non-residency requirement. If one spouse fails it, a joint submission under the foreign procedures is not available, and the IRS domestic procedures apply where one or both spouses fail the requirement. Spouses with different reasons for non-compliance set them out separately in the joint certification.

Our son is at university in the United States. Does he use the same procedure as us in the UK?

Not necessarily. The 330-day test is applied to each person separately. A child who has been in the United States for most of the last three years may fail the non-residency requirement and fall under the Streamlined Domestic Offshore Procedures, which carry a 5 percent miscellaneous offshore penalty and require previously filed returns, while parents living in the UK use the foreign procedures with no penalty.

Is a UK joint account reported on more than one family member's FBAR?

Yes. FinCEN's instructions require each joint owner to report the entire value of a jointly owned account, so an account held by a parent and an adult child appears in full on both FBARs. The only relief is a narrow one for spouses who hold all reportable accounts jointly, file on time and have both signed Form 114a. It does not extend to parents and children.

Does a British spouse with no US status need an ITIN for the family's catch-up?

Only if the couple elects to file a joint US return. The IRS allows a couple to treat a nonresident spouse as a US resident, in which case both report worldwide income and the spouse needs a Social Security number or an ITIN, applied for on Form W-7 with the tax return. If the US citizen files as married filing separately, the British spouse files nothing.

IRS Streamlined Filing Experts: Whole Family Filing

Q: Who files an FBAR for a child with UK savings in their own name?

FinCEN's instructions say a child is generally responsible for filing his or her own FBAR, but where the child cannot file for any reason, such as age, the parent, guardian or other legally responsible person must file it for the child. A parent or guardian signs electronically and enters 'Parent/Guardian filing for child' as the filer title. The report is made in the child's name.

IRS Streamlined Filing Experts handle a whole family by running one coordinated project that ends in several separate submissions, because the Streamlined Filing Compliance Procedures are entered by each taxpayer, or by a married couple filing jointly, and never by a household. One family means one fact-gathering exercise, one document request list and one timetable, but a separate set of returns, a separate certification and a separate payment for every person or couple who is behind. This guide sets out how that works when a US-citizen parent, a spouse, adult children and minor children in the UK all turn out to be non-compliant at the same moment.

Can IRS Streamlined Filing Experts file one submission for a whole family?

No. A streamlined submission is made by an individual taxpayer, and the only combined submission is the one made by spouses who file a joint return. The IRS page for taxpayers abroad, at https://www.irs.gov/individuals/international-taxpayers/us-taxpayers-residing-outside-the-united-states, describes what each taxpayer must do: for each of the most recent 3 years for which the US tax return due date has passed, file delinquent or amended tax returns together with all required information returns; for each of the most recent 6 years for which the FBAR due date has passed, file any late FBARs; and complete and sign the Certification by U.S. Person Residing Outside of the U.S. on Form 14653. Each step is tied to one person's returns and one person's conduct.

A family streamlined project is a single engagement plan that produces as many submissions as there are separate taxpayers in the family, with shared source documents and consistent facts, but with no shared certification. An adult daughter does not appear on her father's Form 14653. A minor son is a separate taxpayer with his own return if he has a filing requirement and his own FBAR if his accounts are reportable.

Who in a UK family actually has a US filing obligation?

The first job is a status review of every family member, because the family's own assumptions are usually wrong in both directions. Whether a child born in the UK acquired US citizenship at birth depends on the parent's own history of presence in the United States and on the law in force when the child was born; it is a question of fact to be established before any return is prepared. Equally, a spouse who has never held a US passport or a green card is usually not a US person, and nothing is filed in that spouse's name unless the couple chooses a joint return. For each person we record the same facts before any numbers are touched:

Status: US citizen by birth in the US, US citizen through a parent, green card holder, or not a US person, with the document that proves it.
Identification: whether a Social Security number exists, and if not, what is needed to obtain one or, for a non-US spouse, an ITIN.
Filing history: which US returns and FBARs have ever been filed, and what they reported.
Physical presence: days inside and outside the United States in each of the last three completed tax years, and whether the person kept a home there.
Accounts: every non-US account in sole name, every joint account, and every account the person can operate for someone else.
Income: earnings, investment income and gains for each year, separated by owner, so a filing requirement can be tested person by person.

Which streamlined procedure does each family member fall under?

There are two routes and the family does not choose one for everybody. The Streamlined Foreign Offshore Procedures are for taxpayers who meet the non-residency requirement and they carry no penalty: the IRS states that a taxpayer who complies will not be subject to failure-to-file and failure-to-pay penalties, accuracy-related penalties, information return penalties or FBAR penalties. Tax and interest are still due. The Streamlined Domestic Offshore Procedures are for taxpayers who fail that requirement, and they carry a miscellaneous offshore penalty which the IRS describes, at https://www.irs.gov/individuals/international-taxpayers/us-taxpayers-residing-in-the-united-states, as equal to 5 percent of the highest aggregate balance or value of the taxpayer's foreign financial assets subject to the penalty across the covered years. The certification differs too: Form 14653 for the foreign route, Form 14654 for the domestic route.

The non-residency requirement is tested person by person. For a US citizen or green card holder, it is met where, in any one or more of the most recent three years for which the US 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. Each family member has a separate day count and so a separate result.

Both routes rest on non-wilful conduct, which the IRS frames as conduct due to negligence, inadvertence or mistake, or the result of a good faith misunderstanding of the requirements of the law. That is a statement about one individual's knowledge. A parent's understanding does not transfer to an adult child, and an adult child's ignorance of the rules establishes nothing about the parent.

What happens when one child is studying in the United States?

This is where family cases diverge. A child who has spent most of the last three years at a US university will have been in the United States for far more than the 35 or so days a year that the 330-day test leaves room for. If that child fails the test in all three years, the foreign procedures are closed to that child even though the parents in London qualify comfortably. The child's case moves to the domestic procedures and the 5 percent miscellaneous offshore penalty, while the parents pay tax and interest with no penalty.

Two points are routinely missed. First, the IRS wording looks at any one or more of the three most recent years, so a student who went to the United States recently may still have one full qualifying year inside the window. That year drops out as time passes, which is a reason to deal with that child's file first. Second, the domestic procedures have an entry condition of their own: the taxpayer must have previously filed a US tax return, if required, for each of the most recent 3 years. A student who filed returns for campus wages but left out UK investment income fits that description and submits amended returns. A student who was required to file and never did does not fit it on the IRS wording, and that position has to be assessed separately before anything is sent.

How do joint filers and a non-US spouse fit into a streamlined submission?

Married couples are the one place where two people share a submission, and the conditions are specific. For the foreign procedures, the IRS states that for joint return filers both spouses must meet the applicable non-residency requirement. For the domestic procedures the mirror image applies: one or both of the spouses must fail it.

The IRS frequently asked questions for the foreign procedures, at https://www.irs.gov/individuals/international-taxpayers/streamlined-filing-compliance-procedures-for-us-taxpayers-residing-outside-the-united-states-frequently-asked-questions-and-answers, deal with joint certifications directly. Where married taxpayers submitting a joint certification have different reasons for their failures, they provide the individual reasons for each spouse separately in the statement of facts. The same page allows a joint amended return with one signature, where a spouse or former spouse will not sign, only if the return shows a net increase in tax. A joint certification is still two people's account of their own conduct, signed by both in the ordinary case.

Where the spouse is not a US person, the couple has a choice to make before the returns are prepared. The US citizen can file as married filing separately and leave the spouse's income out of the US system. Alternatively, the IRS explains at https://www.irs.gov/individuals/international-taxpayers/nonresident-spouse that the couple can choose to treat the nonresident spouse as a US resident for tax purposes, in which case each spouse must report their entire worldwide income for the year the choice is made, a statement signed by both spouses is attached to the joint return, and the spouse must have a Social Security number or an ITIN. The IRS calls it a once-in-a-lifetime choice. Where the non-US spouse holds substantial assets in a sole name, the election changes the size of the project, so we prepare the figures both ways before the family decides.

If the joint route is chosen, the spouse needs an ITIN. The IRS describes an ITIN at https://www.irs.gov/tin/itin/individual-taxpayer-identification-number-itin as a 9-digit number issued to someone who needs a US taxpayer identification number for federal tax purposes, applied for on Form W-7, and it tells applicants to include the tax return in the ITIN application package and not to file it separately.

Do minor children need their own returns and FBARs?

A minor who is a US citizen is a US person in the same way as an adult. FinCEN's FBAR filing instructions, at https://www.fincen.gov/sites/default/files/shared/FBAR%20Line%20Item%20Filing%20Instructions.pdf, define a person as an individual, including a minor child, and state the rule on responsibility: generally, a child is responsible for filing his or her own FBAR; if a child cannot file for any reason, such as age, the child's parent, guardian or other legally responsible person must file it for the child. If the child cannot sign, a parent or guardian must electronically sign and enter 'Parent/Guardian filing for child' as the filer title. The FBAR is the child's report, in the child's name, not an extra page on the parent's.

The trigger is the usual one. The IRS FBAR page at https://www.irs.gov/businesses/small-businesses-self-employed/report-of-foreign-bank-and-financial-accounts-fbar applies the requirement where the aggregate value of the person's foreign financial accounts exceeded $10,000 at any time during the calendar year. In wealthy families children's accounts pass that level early. UK children's tax-free accounts are a frequent example. GOV.UK explains at https://www.gov.uk/junior-individual-savings-accounts that a parent or guardian with parental responsibility can open and manage a Junior ISA but the money belongs to the child, that the child can take control at 16 and cannot withdraw until 18, and that the savings limit for the 2026 to 2027 tax year is £9,000. The UK exemption inside that account is a UK rule; the US return looks at the underlying income, and the account is the child's for FBAR purposes.

Whether the child also needs a US income tax return is a separate test. A dependent child's filing requirement turns on the amount and type of the child's income, with different treatment for earnings and investment income, and the figures change each year, so we test each child against the instructions for each year. A child's investment income above the relevant level can also be taxed by reference to the parent's rate, which means the child's return cannot be finished until the parent's is.

The gap most guides leave is this: a minor with reportable accounts but no income tax filing requirement and no unreported income may not need the streamlined procedures at all. That child's late FBARs are filed through FinCEN's BSA E-Filing System with the reason for late filing explained, as the IRS FBAR page directs for late reports generally.

How are shared and joint accounts reported when several family members file FBARs?

Family accounts overlap, and the FBAR rules do not divide them up. FinCEN's instructions say each joint owner must report the entire value of a jointly owned account, and the form asks for the number of joint owners and the identity of the principal joint owner. An account held by a father and his adult daughter appears in full on his FBAR and in full on hers.

There is one exception and it is narrow. Under FinCEN's instructions the spouse of an individual who files an FBAR need not file a separate report where all the accounts the non-filing spouse must report are jointly owned with the filing spouse, the filing spouse reports them on a timely filed and electronically signed FBAR, and both have completed and signed Form 114a, which the IRS says is kept in the filer's records and not submitted. Otherwise both spouses file separately and each reports the entire value. For a family, several consequences follow:

The exception is for spouses only. It does not cover a parent and child, or two siblings, who hold an account together.
It fails if the non-filing spouse has even one reportable account outside the joint holdings, which is common where each spouse has a personal portfolio.
Signature authority counts as well as ownership. A parent who can operate a child's account may have to list it on the parent's own FBAR while the child's FBAR reports the same account as owner.

For this reason we build one master account schedule for the family, with a row for each account and a column for each person showing whether that person reports it and in what capacity. Every FBAR is drawn from that schedule, so the maximum value of a shared account is identical on each report that carries it. Mismatched values for the same account across two relatives' FBARs is a failure we see in families who used different preparers for different members.

How do you keep each person's narrative consistent without copying one statement for all?

Each certification contains a statement of facts explaining why that person failed to file. In a family the background overlaps heavily: the same move to the UK, the same accountant who never asked about citizenship, the same letter from the bank. Those shared facts must be stated consistently, with the same dates and sequence of events, because the submissions can be read side by side.

What must not be shared is the explanation itself. A father who left the United States as an adult and held a US passport throughout has a different story from a daughter who was born in London and first learned she was a citizen at 23. Pasting his paragraph into her certification puts words in her mouth that are not true of her, in a document she signs personally. Our method is to interview each adult separately, write each narrative from that person's own account, and only then cross-check dates against a shared family chronology. For a minor, the explanation is in substance an account of what the responsible parent knew and did, and it is written and signed as such.

What about confidentiality between adult family members?

An adult child is a separate client, which a parent paying the fees does not always expect. In the engagements we run, each adult signs their own engagement terms and gives their own authority for us to act, and we do not pass one adult's income, balances or draft returns to another without written consent. Because a family project depends on shared information, each adult is asked at the start for a defined consent covering the family chronology, the jointly held accounts and their values, and the timetable. Anything outside that list stays with its owner.

Worked scenario: a family of five with four separate outcomes

The following is an illustration only. The people, balances and income are invented to show the mechanics, and sterling amounts are converted at an assumed rate of $1.30 to £1, which is an assumption for the example and not a published rate. David, 56, was born in Boston and has lived in London since his twenties without filing US returns. His wife Helen, 54, is a British citizen with no US status. Their three children are each assumed to be US citizens from birth through David: Sophie, 25, who works in London; James, 21, in his fourth year at a university in the United States; and Anna, 15, at school in England.

David and Helen. David meets the non-residency requirement in every year. In the illustration Helen holds a £4 million portfolio in her sole name, and the family decides against bringing her worldwide income onto a US return, so David files as married filing separately under the foreign procedures with his own Form 14653. No penalty applies; tax and interest are paid. Helen files nothing but supplies statements for the accounts she holds jointly with David, which he reports in full.
Sophie. She has never lived in the United States and meets the 330-day test in all three years. She makes her own submission under the foreign procedures with her own Form 14653. She holds an account jointly with David containing £80,000, about $104,000 at the assumed rate. The full balance appears on her FBARs and on his.
James. He has been in the United States for most of each of the last three years and fails the non-residency requirement in all of them. He filed US returns for his campus wages but did not report income from a UK investment account in his sole name or file FBARs. He falls under the domestic procedures, files amended returns and Form 14654, and pays the miscellaneous offshore penalty. If the highest year-end aggregate value of his penalty-subject assets were £60,000, about $78,000 at the assumed rate, 5 percent would be about $3,900.
Anna. She has a Junior ISA and a savings account totalling £40,000, about $52,000 at the assumed rate, which is above the $10,000 FBAR level. David files her FBARs as parent, with the filer title completed as FinCEN directs. Whether she needs income tax returns, and so whether she belongs in a streamlined submission or simply needs late FBARs with a reason for late filing, is tested year by year against her actual income.

In what order should the family's cases be prepared?

Sequencing matters because the cases depend on each other. The order is driven by dependencies and risk, not by seniority in the family:

Step 1: status and day counts for everyone, so the number of submissions and the procedure for each is settled first.
Step 2: the master account schedule, from which every FBAR is drawn.
Step 3: the parents' returns, because the filing-status decision and the parent's tax rate feed into the returns of minor children.
Step 4: any family member whose qualifying year is about to leave the three-year window, typically a child who recently moved to the United States.
Step 5: minor children's returns and FBARs, then adult children's submissions, each on its own track and its own signature.
Step 6: a final cross-check of dates, account values and shared facts across every certification before any package leaves.

Current-year deadlines run on a separate clock. The IRS states that the FBAR is due on April 15 following the calendar year reported, with an automatic extension to October 15 that does not need to be requested. Each family member's most recent FBAR and return should be kept on time while earlier years are assembled, so the list of late years does not grow during the project.

What goes on a single family document request list?

One list, issued once, avoids the family being asked for the same statement three times. It is organised by account and by person, and each item is marked with the family members whose filings depend on it:

Passports, birth certificates and any US citizenship documents for each person, plus identity documents for a non-US spouse if an ITIN application is in prospect.
Year-end and highest-balance statements for every non-US account for the six FBAR years, including children's accounts and accounts held with relatives.
Annual tax certificates for investment accounts for the three return years, by owner.
UK tax returns and HMRC calculations for each person who files one, to support foreign tax credit claims and reconcile income between the two systems.
Travel records for each person for the three return years, and US wage statements for any child who has worked in the United States.
Copies of any US returns or FBARs previously filed, and correspondence showing how the issue came to light.

Our role is tax preparation and compliance: establishing who must file, preparing each person's returns, FBARs and certification accurately from that person's own facts, and running the family's cases to a single timetable so that nothing contradicts anything else. If several members of your family have discovered at once that they are behind with the IRS, the starting point is the status review described above, completed for every person before a single return is drafted.
