IRS Voluntary Disclosure Practice: Willful Cases Explained
IRS Voluntary Disclosure Practice for UK-Based US Citizens
When the IRS determines that a US citizen's failure to report foreign bank accounts, offshore income, or foreign trusts was wilful — meaning it was a conscious and intentional disregard of a known legal obligation — the stakes shift dramatically. A wilful FBAR violation carries a penalty equal to the greater of $100,000 or 50% of the account balance per violation, and, in serious cases, the IRS can pursue criminal prosecution rather than a civil settlement. For UK-resident US citizens with significant foreign account balances and years of unreported income, the choice between a non-wilful correction through the streamlined procedures and a wilful case handled through the IRS voluntary disclosure practice is the difference between a manageable penalty and a potentially life-altering exposure to criminal tax prosecution.
This article explains exactly how the IRS voluntary disclosure practice works for willful cases — who it applies to, how the process unfolds, what the IRS expects of participants, and how the outcome compares to being discovered by the IRS without prior disclosure. It is written for UK-resident US citizens who are genuinely concerned that their prior non-compliance may be characterized as wilful and who need to understand the formal voluntary disclosure route before seeking professional advice.
What Is the IRS Voluntary Disclosure Practice?
The IRS voluntary disclosure practice is the formal process through which a taxpayer who has committed potential criminal tax violations — including wilful failure to file FBARs, wilful tax evasion, or filing false returns — can come forward voluntarily, make a complete and accurate disclosure of all unreported income and accounts, pay all taxes, interest, and agreed penalties, and in return receive a commitment from the IRS that it will recommend no criminal prosecution. Furthermore, the program is governed by IRS Criminal Investigation and administered by submitting Form 14457 — the Voluntary Disclosure Practice Preclearance Request and Application — rather than through the standard examination or collection channels. Specifically, the IRS voluntary disclosure practice is available only to taxpayers who have not already been contacted by the IRS regarding the matters being disclosed, who have not been the subject of a civil examination or criminal investigation for the years covered, and who make a timely, complete, and accurate disclosure of all unreported matters — not just the ones they believe the IRS already knows about. The IRS Criminal Investigation voluntary disclosure practice guidance is at https://www.irs.gov/compliance/criminal-investigation/voluntary-disclosure-practice.
Why the Voluntary Disclosure Practice Matters in 2026
FATCA Data Exchange Has Eliminated Practical Anonymity
The Foreign Account Tax Compliance Act requires foreign financial institutions — including every UK bank, building society, and investment platform — to identify US-citizen account holders and report their account information to HMRC, which then exchanges that data with the IRS through the annual FATCA information exchange. Furthermore, this exchange has been operating since 2015 and has produced a substantial database of UK accounts held by US citizens that the IRS can cross-reference against FBAR filing histories. Consequently, a UK-resident US citizen with a Barclays current account, an ISA at Hargreaves Lansdown, and a pension with Aviva has almost certainly had all three accounts reported to the IRS through the FATCA channel — and a failure to disclose those accounts voluntarily before the IRS initiates an examination is precisely the circumstance that removes access to the voluntary disclosure program. According to https://www.aicpa.org, FATCA data matching is now the primary driver of international tax enforcement referrals to IRS Criminal Investigation.
The Post-OVDP Landscape and the Current Program
The IRS Offshore Voluntary Disclosure Program — which ran from 2009 to 2018 and provided a structured penalty framework for offshore non-compliance — closed permanently in September 2018. Furthermore, since the OVDP closure, the only formal route for wilful offshore non-compliance has been the current voluntary disclosure practice, which does not provide a fixed-penalty framework and instead requires case-by-case negotiation with IRS Criminal Investigation examiners. Consequently, the current IRS voluntary disclosure practice typically results in higher penalties and a less predictable outcome than the closed OVDP — making early professional engagement and a well-prepared submission more important than under the structured OVDP framework that preceded it. The IRS guidance on Form 14457 is at https://www.irs.gov/forms-pubs/about-form-14457.
What Distinguishes Wilful from Non-Wilful
The distinction between wilful and non-wilful FBAR violations is not always as clear as the IRS makes it out to be, and the characterization has been the subject of significant US federal court litigation. Furthermore, in the landmark Bittner v United States decision of 2023, the US Supreme Court held that the per-account wilful FBAR penalty applies on a per-form basis rather than per-account — reducing but not eliminating the exposure for multi-account wilful cases. Specifically, wilfulness in the FBAR context includes both deliberate disregard — knowing about the FBAR requirement and choosing not to comply — and reckless disregard — taking a substantial and unjustifiable risk that the FBAR was required without checking. Consequently, a UK-resident US citizen who was advised to open a UK bank account without disclosing it on the FBAR and who followed that advice without independent inquiry may face a reckless disregard-wilfulness argument — making the IRS voluntary disclosure practice the appropriate route rather than the streamlined procedures.
How the IRS Voluntary Disclosure Practice Works
Step 1 — Preclearance Request via Form 14457 Part I
The voluntary disclosure process begins with the submission of Form 14457 Part I — the preclearance request — to IRS Criminal Investigation, confirming the taxpayer's identity and requesting confirmation that they are not already under criminal investigation for the matters being disclosed. Furthermore, the preclearance request must be submitted before any civil examination is opened for the years being disclosed, as an active examination removes the taxpayer from eligibility for the voluntary disclosure program. Additionally, the preclearance request does not disclose the specific nature of the violations — it simply requests clearance to participate in the program — and IRS Criminal Investigation typically responds within a few weeks with either clearance to proceed or a notification that the taxpayer is ineligible. Preclearance is a threshold requirement, not a guarantee of any particular outcome. The IRS Form 14457 and instructions are at https://www.irs.gov/forms-pubs/about-form-14457.
Step 2 — Full Disclosure Submission via Form 14457 Part II
Once preclearance is granted, the taxpayer submits Form 14457 Part II — the full voluntary disclosure application — disclosing all unreported income, all unreported foreign accounts, and all years of non-compliance within the covered disclosure period, which is typically the prior six years. Furthermore, the Part II submission must be complete and accurate — the IRS voluntary disclosure practicerequires disclosure of everything, not just the matters the taxpayer believes the IRS already knows — since a selective or incomplete disclosure is treated as a failure to participate in the program and removes the criminal prosecution protection. Additionally, the Part II submission must include amended returns for all covered years, FBARs for each year with unreported accounts, all relevant international information returns, and a computation of the tax, interest, and proposed penalty. The narrative accompanying the disclosure must explain the nature and circumstances of the non-compliance without attempting to minimize the taxpayer's culpability in a way that appears dishonest.
Step 3 — Examination and Penalty Negotiation
After the Part II submission, IRS Criminal Investigation refers the case to the Civil Examination function for review — a process that typically involves an examination of the amended returns, a review of the disclosed accounts and income, and negotiation of the civil penalties. Furthermore, unlike the streamlined procedures — which apply a fixed 5% miscellaneous offshore penalty — the IRS voluntary disclosure practice produces a negotiated penalty that can range from 50% of the highest aggregate unreported account balance to 75% of the unpaid tax, depending on the examiner's assessment of the taxpayer's culpability, cooperation, and the quality of the disclosure. Additionally, the penalty negotiation is conducted between the taxpayer's representative and the IRS examiner, with the examiner having significant discretion within the IRS penalty guidelines — making the quality of the legal and tax representation in this phase one of the most significant variables in the final outcome.
Step 4 — Closing Agreement and Payment
The voluntary disclosure process concludes with the execution of a closing agreement — Form 906 — that documents the agreed penalties, the tax and interest due, and the terms of the settlement. Furthermore, the closing agreement provides the taxpayer with finality for the covered years and — most importantly — the confirmation that IRS Criminal Investigation will not recommend criminal prosecution for the matters disclosed. Additionally, payment of the full agreed amount is required at closing, and the failure to pay in full on the agreed terms can reopen the criminal prosecution exposure that the disclosure was designed to eliminate. The IRS Form 906 closing agreement process is explained at https://www.irs.gov/compliance/criminal-investigation/voluntary-disclosure-practice.
Step 5 — Coordinate UK Tax Implications of the Disclosure
For a UK-resident US citizen, the voluntary disclosure for US purposes may have parallel UK tax implications — particularly where the unreported US income also included UK-source income that should have been reported on the UK self-assessment return, or where offshore accounts included funds that are subject to UK income tax or CGT under the UK's territorial tax rules. Furthermore, the amended US returns and the penalty payments made through the voluntary disclosure may generate foreign tax credits that affect the UK tax calculation for the same years — creating a need for the UK self-assessment returns to be reviewed alongside the US disclosure. Additionally, where the UK self-assessment returns for the covered years also require amendment — because UK-source income was incorrectly reported or offshore income was not disclosed under the remittance basis — those amendments should be coordinated with the US voluntary disclosure to ensure consistency between the two jurisdictions' records. The HMRC guidance on voluntary disclosure for UK tax purposes is at https://www.gov.uk/guidance/tell-hmrc-about-underpaid-tax-from-previous-years.
Case Study: UK-Resident US Citizen, Wilful FBAR Exposure
Our team was engaged by a US citizen who had lived in Manchester for sixteen years and who had maintained a Swiss investment account containing approximately $1.8 million throughout his UK residence. The account had been opened in Switzerland before the client moved to the UK and had been managed by a Swiss private bank. The client had been specifically advised by a Swiss banker in 2009 that the account did not need to be disclosed to the IRS — advice that was incorrect but that the client relied on without independent verification for the following fourteen years. The account had generated approximately $60,000 per year of investment income that was neither reported on the US return nor included on the FBAR for any year.
After reviewing the facts, we advised the client that the IRS voluntary disclosure practice was the appropriate route — rather than the streamlined procedures — for two reasons. First, the client had received incorrect advice but had not sought independent verification of that advice for 14 years, despite becoming aware through press coverage of FATCA and FBAR enforcement that US persons were required to report foreign accounts. Second, the $1.8 million account balance produced a wilful FBAR penalty exposure of up to $900,000 per year under the 50% rule. This exposure made the criminal prosecution protection under the voluntary disclosure program significantly more valuable than that of the streamlined program.
We submitted Form 14457 Part I and received preclearance within three weeks. Furthermore, the Part II disclosure covered six years of amended returns, six years of FBARs for the Swiss account, and a computation of approximately $210,000 of unreported tax and interest across the six covered years. Additionally, the penalty negotiation with the IRS examiner resulted in an agreed civil penalty of $540,000 — representing 30% of the highest aggregate account balance over the covered period — which, while substantial, was significantly lower than the theoretical maximum and confirmed that no criminal prosecution referral was made. The total cost of the voluntary disclosure — tax, interest, and penalty — was approximately $795,000, compared with a theoretical maximum civil penalty alone of over $5.4 million under the per-year 50% rule for six years of wilful violations.
Common Mistakes with the Voluntary Disclosure Practice
Mistake 1 — Using the Streamlined Procedures When the Case Is Wilful
The most dangerous mistake for a potentially wilful taxpayer is submitting under the streamlined procedures — which require a Form 14653 certification that the non-compliance was non-wilful — when the facts support a wilful characterization. Furthermore, if the IRS later determines that the non-wilfulness certification was false, the taxpayer faces both the standard wilful FBAR penalties and criminal prosecution for filing a false certification — a worse outcome than entering the IRS voluntary disclosure practice in the first place. The correct approach requires wilfulness of the facts before selecting between the streamlined procedures and the voluntary disclosure program — a determination that only an experienced cross-border tax professional can make accurately. IRS voluntary disclosure guidance is at https://www.irs.gov/compliance/criminal-investigation/voluntary-disclosure-practice.
Mistake 2 — Making an Incomplete Disclosure
The voluntary disclosure program requires disclosure of all unreported matters — all accounts, all income sources, all years within the covered period. Furthermore, taxpayers who disclose their Swiss account but fail to mention a Cayman Islands investment or a UK rental income stream that was also unreported are making an incomplete disclosure that destroys the criminal prosecution protection for the entire submission. The correct approach requires a comprehensive audit of all unreported income, assets, and accounts for all covered years before the Part II submission is filed — since there is no opportunity to supplement an incomplete disclosure after it is submitted.
Mistake 3 — Waiting Too Long After Learning of the Requirement
The voluntary disclosure program is available only to taxpayers who come forward before the IRS initiates contact regarding the unreported matters. Furthermore, a UK-resident US citizen who receives a letter from their UK bank informing them that their account information has been reported to HMRC under FATCA — and who then waits to see whether the IRS contacts them before deciding whether to disclose — has significantly increased their risk of losing access to the program. The correct approach requires initiating the voluntary disclosure as soon as a potential wilfulness concern is identified, before any IRS contact occurs.
Mistake 4 — Attempting the Disclosure Without Specialist Representation
IRS Criminal Investigation manages the IRS voluntary disclosure practice and involves penalty negotiation with experienced federal examiners. Furthermore, a taxpayer who represents themselves in the Part II submission and penalty negotiation — or who uses a UK accountant without US criminal tax experience — is at a significant disadvantage compared with a taxpayer represented by a qualified US attorney or Enrolled Agent with specific experience in voluntary disclosure. The correct approach requires engaging a specialist cross-border adviser from the preclearance stage, not after the Part II submission is rejected or a higher-than-expected penalty is proposed.
Mistake 5 — Not Coordinating the UK Self-Assessment Position
A UK-resident US citizen who completes the voluntary disclosure for US purposes and pays the US tax, interest, and penalties without reviewing the corresponding UK self-assessment returns may have an inconsistent filing position — where the US amended returns show income that was not reported on the UK return for the same years. Furthermore, the UK's Worldwide Disclosure Facility provides a parallel route for correcting UK tax non-compliance, and coordinating the two disclosures ensures consistency across the records of both jurisdictions. The correct approach requires a IRS voluntary disclosure practice adviser who understands both the US voluntary disclosure program and the UK's equivalent correction mechanisms to review both sets of returns simultaneously. HMRC Worldwide Disclosure Facility guidance is at https://www.gov.uk/guidance/worldwide-disclosure-facility-make-a-disclosure.

Conclusion
The IRS voluntary disclosure practice for willful cases is the most serious compliance correction route available to US citizens with significant offshore non-compliance — protecting them from criminal prosecution in exchange for complete disclosure, full payment of tax and interest, and acceptance of a negotiated civil penalty. Furthermore, the distinction between wilful and non-wilful non-compliance is not always clear from the facts, and the consequence of incorrectly applying the streamlined procedures when the case is genuinely wilful — a false non-wilfulness certification — results in a worse outcome than the voluntary disclosure program itself. Moreover, for UK-resident US citizens whose UK bank accounts have been reported to the IRS through the FATCA exchange, the window of opportunity to make a voluntary disclosure before the IRS initiates contact is narrowing — making early professional assessment of the wilfulness question one of the most time-sensitive decisions in cross-border tax compliance.
The three most important actions for any UK-resident US citizen who is concerned about wilful offshore non-compliance are: first, conduct a comprehensive review of all unreported accounts, income, and information returns before making any disclosure decision — since an incomplete disclosure is worse than no disclosure; second, obtain a specific wilfulness analysis from a qualified cross-border adviser before selecting between the streamlined procedures and the voluntary disclosure programme; and third, initiate the preclearance request through Form 14457 before the IRS makes contact, since loss of the voluntary disclosure programme leaves only the civil examination and criminal investigation channels available.

FAQs
Q: What is the IRS voluntary disclosure practice, and who is it for?
The IRS voluntary disclosure practice is the formal process for taxpayers who have committed potential criminal tax violations — including wilful FBAR non-compliance and wilful tax evasion — to come forward before IRS contact, make a complete disclosure, pay all taxes and agreed penalties, and receive a commitment that criminal prosecution will not be recommended.
Q: What is the difference between the streamlined procedures and the voluntary disclosure practice?
The streamlined procedures apply to non-wilful non-compliance and require a Form 14653 non-wilfulness certification. The voluntary disclosure practice applies to wilful non-compliance. Using streamlined procedures when the case is wilful — and falsely certifying non-wilfulness — creates criminal exposure for the false certification on top of the underlying violation.
Q: What penalties apply under the IRS voluntary disclosure practice?
The penalties are negotiated on a case-by-case basis with the IRS examiner. There is no fixed penalty structure since the OVDP closed in 2018. Penalties typically range from 50% of the highest aggregate unreported account balance to 75% of the unpaid tax, depending on culpability and cooperation. Criminal prosecution is not recommended where the disclosure requirements are fully met.
Q: What does Form 14457 do in the voluntary disclosure practice?
Form 14457 has two parts. Part I is the preclearance request, submitted to IRS Criminal Investigation to confirm the taxpayer is not already under investigation. Part II is the full disclosure application, submitted after preclearance is granted, containing the complete disclosure of all unreported matters, amended returns, and penalty computation.
Q: Can a UK-resident US citizen use the voluntary disclosure practice?
Yes. UK-resident US citizens are eligible for the IRS voluntary disclosure program, in which their non-compliance may be characterized as wilful. The same eligibility requirements apply — no prior IRS contact on the matters being disclosed, complete and accurate disclosure, and full payment of tax, interest, and agreed penalties.
Q: What happens if the IRS contacts me before I make a voluntary disclosure?
IRS contact regarding the matters you intend to disclose — whether an examination notice, an FBAR penalty letter, or a criminal investigation referral — removes your eligibility for the voluntary disclosure program for those matters. The civil examination or criminal investigation then proceeds without the protection that the voluntary disclosure program would have provided.
