Behind on US Taxes After Setting Up a UK Trust? How Streamlined Filing Works
Being behind on US taxes after setting up a UK trust is a position no US taxpayer wants to find themselves in—yet it is remarkably common. A UK trust established for legitimate estate planning, asset protection, or family wealth transfer purposes can trigger a cascade of US reporting obligations that many taxpayers only discover years later. If you have fallen behind on US taxes after setting up a UK trust, the IRS Streamlined Filing Compliance Procedures offer a structured, penalty-mitigated pathway back to full compliance.
This guide explains exactly how streamlined filing works, who qualifies, and the steps you must take to resolve your tax situation before the IRS makes contact.
What Does It Mean to Be Behind on US Taxes After Setting Up a UK Trust?
When you establish, contribute to, or receive distributions from a UK trust, you trigger specific US tax reporting obligations under the Internal Revenue Code. Being behind on US taxes when setting up a UK trust typically means one or more of the following has occurred:
- Unfiled Form 3520: Required when a US person creates a foreign trust, transfers assets to a foreign trust, or receives distributions from a foreign trust
- Unfiled Form 3520-A: Required annually for foreign trusts with at least one US owner
- Unfiled FBAR (FinCEN Form 114): Required if the trust holds foreign bank accounts and the US person has signature authority or financial interest
- Unfiled Form 8938: Required to report specified foreign financial assets, including foreign trust interests
- Unreported trust income: Distributable net income from a foreign non-grantor trust taxable to the US beneficiary
- Unreported grantor trust income: All income of a foreign grantor trust taxable to the US owner, even if not distributed
The penalties for these failures are severe. Form 3520 penalties start at the greater of $10,000 or 35% of the transaction value. FBAR penalties can reach $10,000 per account per year for non-willful violations, and the greater of $100,000 or 50% of the account balance for willful violations. For taxpayers behind on US taxes setting up a UK trust, the cumulative exposure can exceed the value of the trust itself.
Why Setting Up a UK Trust Creates US Tax Filing Obligations
Understanding why you fell behind on US taxes when setting up a UK trust requires understanding how the IRS classifies foreign trusts. A trust is "foreign" if it fails either the court test (a US court does not exercise primary supervision over the trust's administration) or the control test (no US person has authority to control substantial trust decisions). Virtually every trust established under English law with UK trustees is a foreign trust in the IRS's eyes.
This classification triggers obligations that many UK solicitors and wealth managers—however competent in UK law—fail to identify:
The Foreign Grantor Trust
If the US person who created the trust retains certain powers (including powers standard in UK trust deeds, such as the power to appoint trustees or direct investments), the IRS classifies it as a foreign grantor trust. All trust income becomes taxable to the US grantor personally, every year, regardless of whether any distribution is made. The grantor must file Form 3520-A annually.
The Foreign Non-Grantor Trust
If the US person is a beneficiary but not the grantor, or if the grantor has not retained sufficient powers, the trust is a foreign non-grantor trust. Distributions to US beneficiaries carry out distributable net income (DNI) taxable at ordinary income rates, plus an interest charge on the tax deferral—the "throwback tax." Each distribution triggers a Form 3520 filing obligation.
The Accidental American Settlor
A particularly challenging scenario arises when a UK-domiciled individual establishes a UK trust for family purposes, unaware that they hold US citizenship by birth. This Accidental American may have lived their entire life outside the United States, yet the IRS classifies their UK family trust as a foreign grantor trust, requiring years of unfiled returns and forms.

How the IRS Streamlined Filing Procedures Resolve the Problem
The IRS Streamlined Filing Compliance Procedures are specifically designed for taxpayers who have fallen behind on US taxes and set up a UK trust due to non-willful conduct. The program provides two pathways:
Streamlined Foreign Offshore Procedures (SFOP)
Who Qualifies:
- US taxpayers residing outside the United States
- Physical presence outside the US for at least 330 full days in one of the three most recent tax years
- Non-willful failure to report foreign financial assets and pay tax
- Not under IRS civil examination or criminal investigation
What You File:
- Three years of amended or delinquent federal tax returns
- Six years of FBARs (FinCEN Form 114)
- Form 14653 (Certification by US Person Residing Outside the United States) with a detailed non-willful narrative
The Benefit:
- No penalties for failure to file FBARs, Form 8938, or tax returns
- No accuracy-related penalties on underpayments
- Waiver of all failure-to-file and failure-to-pay penalties
Streamlined Domestic Offshore Procedures (SDOP)
Who Qualifies:
- US taxpayers residing in the United States
- Non-willful failure to report foreign financial assets and pay tax
- Previously filed original tax returns (if required to file)
- Not under IRS civil examination or criminal investigation
What You File:
- Three years of amended federal tax returns
- Six years of FBARs
- Form 14654 (Certification by US Person Residing in the United States) with a detailed non-willful narrative
The Benefit:
- A single Title 26 miscellaneous offshore penalty of 5% of the highest aggregate year-end balance of unreported foreign financial assets
- Waiver of all other failure-to-file, failure-to-pay, and accuracy-related penalties
For taxpayers behind on US taxes setting up a UK trust, the Streamlined Foreign Offshore Procedures are particularly valuable. A UK resident who established a UK trust, unaware of the US filing obligations, can potentially resolve years of non-compliance without paying a single dollar in penalties.
The Non-Willful Certification: The Make-or-Break Requirement
The entire streamlined filing process for those behind on US taxes setting up a UK trust hinges on one critical certification: the filer must state under penalties of perjury that their failure to report was non-willful.
Non-willful conduct means the failure resulted from negligence, inadvertence, mistake, or a good-faith misunderstanding of the law. Willful conduct—knowingly failing to file or acting with reckless disregard of a known legal duty—disqualifies the filer from streamlined treatment and potentially exposes them to criminal investigation.
For taxpayers behind on US taxes setting up a UK trust, the non-willful analysis considers:
- Reliance on UK professional advice: If a UK solicitor or wealth manager advised that the trust had no US tax implications, this strongly supports non-willfulness
- The taxpayer's connection to the US: An Accidental American who has never lived in the US has a compelling non-willful narrative
- Nature of the trust: An openly declared trust at a reputable UK institution supports non-willfulness; nominee structures or concealed accounts suggest otherwise
- Consistency of conduct: Did the taxpayer report other foreign assets while omitting the trust? A pattern of partial compliance requires careful explanation.
The IRS scrutinizes streamlined certification. The non-willful narrative must be detailed, internally consistent, and supported by documentary evidence. At TaxYork, we prepare robust certification statements that withstand IRS review.
Step-by-Step: Resolving Your Situation When Behind on US Taxes Setting Up a UK Trust
Step 1: Do Not File Anything Until You Have Professional AdviceThe single most dangerous step you can take is to begin filing Forms 3520, 3520-A, or amended tax returns without a comprehensive strategy. Partial or inconsistent filings can prejudice your access to the streamlined procedures. Engage a qualified US tax professional immediately.
Step 2: Establish Attorney-Client PrivilegeIf there is any possibility that your conduct could be characterized as willful, engage a US tax attorney before speaking to any accountant. Communications with attorneys are privileged; communications with accountants generally are not. The attorney can engage TaxYork under a Kovel arrangement to extend privilege to the accounting analysis.
Step 3: Complete a Comprehensive Trust and Asset InventoryIdentify every trust you have created, contributed to, or received distributions from. For each trust, obtain:
- The trust deed and any amendments
- Trustee names and addresses
- Trust bank account statements
- Records of all contributions and distributions
- UK tax filings related to the trust
Step 4: Determine Trust ClassificationClassify each trust for US tax purposes: foreign grantor trust, foreign non-grantor trust, or US domestic trust. This classification drives all subsequent tax calculations and form filings.
Step 5: Calculate Tax and Penalty ExposureCalculate the correct US tax liability for the three streamlined years (and earlier years if required). Compute distributable net income for foreign non-grantor trusts. Determine grantor trust income taxable to the US owner. Model the penalty exposure absent streamlined relief to understand the value of the program.
Step 6: Assess Non-WillfulnessWith the guidance of counsel, determine whether your conduct qualifies as non-willful. If it does not, the streamlined procedures are not available, and alternative strategies—including potentially the Voluntary Disclosure Program—must be evaluated.
Step 7: Prepare and Submit the Streamlined PackageFile three years of amended or delinquent tax returns with all required information returns (Forms 3520, 3520-A, 8938, and 5471 as applicable). File six years of FBARs. Submit the certification form with a comprehensive non-willful narrative. Pay any additional tax and interest due, plus the 5% penalty if filing under domestic procedures.
Step 8: Implement Ongoing ComplianceEstablish a compliance calendar to ensure all future filings are completed on time. For UK trusts with US owners or beneficiaries, this means annual Forms 3520-A, FBARs by April 15 (with automatic extension to October 15), and Forms 8938 with the annual tax return.
Common Mistakes When Catching Up on US Taxes After Setting Up a UK Trust
- Filing Forms 3520 late while still within the streamlined window: A late-filed Form 3520 automatically triggers penalty assessments. The streamlined procedures should be completed first to waive these penalties.
- Assuming the UK trust is a grantor trust without analysis: Not all trusts created by US persons are grantor trusts. Misclassification leads to incorrect income reporting and potential underpayment.
- Failing to account for throwback tax on prior distributions: Beneficiaries of foreign non-grantor trusts must pay interest on the tax deferral for distributions of accumulated income from prior years. This interest charge can be substantial.
- Submitting a generic non-willful narrative: The IRS rejects certifications that lack a specific, detailed explanation of the taxpayer's individual circumstances. The narrative must tell a coherent, verifiable story.
- Missing the PFIC dimension: If the UK trust holds non-US mutual funds, ETFs, or pooled investment vehicles, these are likely Passive Foreign Investment Companies (PFICs) requiring additional reporting on Form 8621. PFIC taxation is punitive and must be addressed within the streamlined process.
