For a high-net-worth family, an offshore trust is usually a sensible, legitimate structure — a vehicle for succession planning, asset protection, and privacy. The problem arises when a US person is connected to that trust and no one ever told the IRS. American settlors, owners, and beneficiaries have annual reporting duties that have nothing to do with whether the trust is “offshore” in any sinister sense. When those duties are missed, the Streamlined Foreign Offshore Procedures are the route that lets non-willful taxpayers put it right without crippling penalties.
This guide explains how the program works for families with an undisclosed foreign trust, what must be filed, and how to build a disclosure that holds up.
The Streamlined Foreign Offshore Procedures are one half of the IRS streamlined program, designed specifically for US taxpayers who live outside the United States. Because America taxes citizens on worldwide income, a US person never ceases to have US filing obligations simply by moving abroad or by holding assets through a non-US structure. The program exists for people who fell out of compliance because they did not know the rules, misunderstood them, or were wrongly advised — not because they set out to hide anything.
The foreign version is the more generous of the two streamlined routes. Taxpayers who meet the non-residency test and certify non-willful conduct pay only the additional tax and statutory interest. The miscellaneous offshore penalty that applies to the domestic version is waived entirely. For a family carrying years of unreported trust connections, that distinction can be worth a great deal.
An offshore trust rarely causes a reporting failure on its own. The failure happens because the US reporting web around a foreign trust is wide and unintuitive. A US person who is treated as an owner of any portion of a foreign trust must ensure that a Form 3520-A is filed annually to report the trust’s activity. A US person who creates a foreign trust, transfers assets to it, or receives a distribution from it must file Form 3520. On top of that, the individual may have FBAR duties for trust bank accounts and Form 8938 duties for specified foreign assets.
Families are caught off guard because the trust was often established by an earlier generation, administered by overseas trustees, and simply never discussed in US tax terms. A beneficiary who later moves to London, or a younger family member who naturalizes, can inherit a reporting problem they did not create. The Streamlined Foreign Offshore Procedures were built to absorb precisely this kind of innocent, inherited non-compliance.
Three conditions must be satisfied. First, the non-residency test: in at least one of the most recent three years for which the deadline has passed, the taxpayer must have lived outside the United States for at least 330 full days and not maintained a US abode. Second, the conduct must be non-willful — the result of negligence, inadvertence, mistake, or a good-faith misunderstanding of the law. Third, the IRS must not already have opened a civil examination or criminal investigation of the taxpayer.
For a family with members in both countries, each US person is assessed individually. A relative in London who satisfies the non-residency test can use the foreign route, while a relative in New York with the same trust connection would use the domestic route, which carries a 5 percent penalty. Mapping who files what — and under which route — is an essential early step.
A streamlined submission under the Streamlined Foreign Offshore Procedures has a defined shape, and trust cases add specific forms on top of the standard package.
The core package is three years of tax returns (original or amended) and six years of FBARs. Trust-connected taxpayers must then ensure the relevant trust forms are included for those years: Form 3520 for transfers to, ownership of, or distributions from the foreign trust, and Form 3520-A for the trust itself where there is a US owner. Specified foreign financial assets above the threshold are reported on Form 8938. The submission is completed by Form 14653, the signed non-willfulness certification, and payment of the tax and interest due.
Because trust accounting can be complex — distributions, accumulated income, and the throwback rules all interact — rebuilding accurate figures is often the most demanding part of the work.

Trust families with a genuinely non-willful history and members abroad are usually best served by the Streamlined Foreign Offshore Procedure. Still, a specialist should always confirm the right route before filing.
The most common mistake is treating the trust as “not really mine” — assuming that because overseas trustees run it, there is nothing to report. US ownership and beneficiary rules look through that. A second mistake is filing personal returns under the streamlined program while quietly omitting Forms 3520 and 3520-A, which leaves the very exposure the family wanted to fix. A third is undervaluing or guessing trust figures rather than reconstructing them properly. A fourth is a vague certification: the IRS expects a concrete account of how the misunderstanding arose across what may be several family members. A fifth is delayed — foreign-trust penalties escalate, and waiting until the IRS makes contact removes streamlined eligibility altogether.
Consider a US citizen living in London whose grandfather, decades ago, settled a discretionary trust in a low-tax jurisdiction for the benefit of the wider family. The trust was administered by professional trustees overseas and had simply always been there in the background of family life. Our taxpayer had received two modest distributions in his thirties and was named as a discretionary beneficiary. Still, no one had ever mentioned a US filing duty — the trust pre-dated his own tax awareness entirely.
When he reviewed his position with a cross-border adviser, two issues emerged. He should have filed Form 3520 in the years he received distributions, and, depending on how the trust was structured and controlled, ownership questions needed careful analysis. His conduct was non-willful by any reasonable measure: he had inherited a structure, not concealed one. Using the Streamlined Foreign Offshore Procedures, his adviser reconstructed three years of returns, included the relevant trust forms, filed six years of FBARs for his own UK accounts, and certified the full history on Form 14653.
The result was complete compliance with no offshore penalty. Just as importantly, the family put a process in place so that future distributions and any ongoing ownership reporting were handled correctly every year, ending the quiet cycle of inherited non-compliance. This pattern — an honest taxpayer connected to a structure built by an earlier generation — is the single most common foreign-trust scenario advisers see.
It is worth being concrete about what the Streamlined Foreign Offshore Procedures protect you from, because the contrast is stark. Outside a disclosure program, a missed Form 3520-A can attract a penalty equal to the greater of 10,000 US dollars or 5 percent of the trust assets treated as owned by the US person. A missed Form 3520 can attract a penalty of up to 35 percent of unreported contributions or distributions. Continuation penalties of an additional 10,000 US dollars per 30-day period can stack on top of one another once the IRS issues a notice and the form remains unfiled.
FBAR penalties are a separate regime again, and FATCA penalties for a missed Form 8938 add yet another layer. For a family connected to a substantial trust across several years and several individuals, the theoretical exposure can run well into six figures before any actual tax is even considered. The streamlined program replaces all of that with the actual tax and interest — nothing more — for taxpayers who qualify under the foreign route. That single fact is the entire reason coming forward voluntarily, on your own terms and timetable, is so much stronger than waiting to be found.
The streamlined program rewards taxpayers who come forward on their own initiative, and timing is part of that. Eligibility ends the moment the IRS opens an examination or investigation, so the value of the Streamlined Foreign Offshore Procedures is at its highest before any contact is made. Foreign-trust penalties also escalate over time, and incomplete historic records become harder to recover with each passing year. None of this means rushing a submission — accuracy still matters far more than speed — but it does mean that a family aware of an unreported trust should begin the work deliberately rather than letting it drift.
Disclosing an offshore trust is a cross-border project, not a single tax return, and it benefits from advisers who understand both the US reporting regime and the UK tax treatment of the same structure. As specialist accountants for US and UK families and trust planning, Jungle Tax maps the structure, identifies every connected US person, reconstructs trust data, and prepares Forms 3520 and 3520-A as part of the core streamlined package.
The firm also advises high-net-worth individuals across the US and the UK on keeping trust structures compliant going forward and works with US tax advisors to coordinate filings for family members in different countries. The goal is a clean disclosure now and a calm reporting position every year after.
An undisclosed offshore trust is rarely the result of wrongdoing — far more often it is a structure set up by a previous generation that quietly outgrew the family’s understanding of US rules. The Streamlined Foreign Offshore Procedures give non-willful families a dignified, penalty-free way to correct it. Still, the window depends on coming forward before the IRS does and on accurately certifying the high story.

They are the IRS streamlined route for US taxpayers living abroad who failed to report foreign income or assets non-willfully, allowing them to become compliant without incurring an offshore penalty.
Possibly. If you are treated as an owner of any part of the trust, annual reporting on Form 3520-A is required regardless of whether you took a distribution.
Outside a disclosure program, penalties can be the greater of 10,000 US dollars or a percentage of trust contributions, distributions, or value, which is why the streamlined route is valuable.
Yes. Each US person is assessed individually, so a relative abroad may use the foreign route while a relative in the US uses the domestic route.
Three years of tax returns and six years of FBARs, with the relevant trust forms included for those years.
You may still have current reporting duties. The program is designed for exactly this kind of inherited, non-willful situation.
Yes, the streamlined program remains open, though the IRS can change or end it at any time, so acting promptly is sensible.
