Voluntary disclosure programs are the principal mechanism through which tax authorities recover unpaid crypto taxes without criminal prosecution. The data tells a striking story: programs with punitive penalty structures attract almost no participants, while programs with proportionate penalties can collect billions of dollars and bring tens of thousands of taxpayers into compliance within months. As crypto-specific enforcement infrastructure tightens globally with IRS Form 1099-DA reporting live for tax year 2025 and HMRC’s Cryptoasset Reporting Framework active from January 2026 the window for voluntary disclosure before enforcement contact is narrowing.
At KoinX, we track the statistical record of voluntary disclosure programs to help investors understand what participation means in practice: how many come forward, how much they pay, and how penalties compare with the cost of being caught.
This article covers: the current IRS Criminal Voluntary Disclosure Practice (VDP) and its critically low participation; the historical OVDP programs that collected $11.1 billion; the ERC Voluntary Disclosure Programs of 2023 and 2024; proposed 2026 VDP reforms; the IRS Streamlined Filing Compliance Procedures as the dominant alternative pathway; and HMRC’s cryptoasset disclosure framework.
Scope and Methodology
All statistics in this article originate from primary sources that pass a strict source test: the organization cited must have produced the data itself, and each URL resolves to the specific report, filing, regulatory document, or official news release not to a homepage or aggregator. Secondary sources, news aggregators, and commentary without disclosed primary data were excluded.
The primary geographic focus is the United States and the United Kingdom. Figures are drawn from the IRS Taxpayer Advocate Service (TAS) Annual Report to Congress 2024, IRS news releases, the US GAO report GAO-13-318, the IRS CI VDP proposal of December 2025, and HMRC regulatory documents. Each bullet contains at least 1 explicit numerical value. No statistics were synthesized, inferred, or combined across sources.
IRS Criminal Voluntary Disclosure Practice (VDP): Participation Statistics
- The IRS Criminal VDP has completed only 161 cases in the approximately 6 years from its restructuring on September 28, 2018, through August 31, 2024 an average of fewer than 27 completed cases per year based on the National Taxpayer Advocate Annual Report to Congress 2024, Most Serious Problem 10.
- The Taxpayer Advocate Service (TAS) identified the current IRS Criminal VDP as one of the Most Serious Problems facing taxpayers, stating that the program’s 75% civil fraud penalty requirement had made it sufficiently unattractive that practitioners reported being less likely to recommend it to clients a deterrence effect that the TAS attributed directly to the 6-year total of only 161 completed cases, based on the TAS 2024 Annual Report to Congress.
- The IRS began tracking tax, interest, and penalties collected through the VDP only from May 2024, meaning no revenue data exists for the approximately 5.5 years of VDP operation before that date, and the program’s financial impact on the tax gap was unmeasurable prior to that point based on the TAS 2024 Annual Report to Congress, Most Serious Problem 10.
- On December 22, 2025, the IRS opened a 90-day public comment period closing March 22, 2026 on proposed updates to its Voluntary Disclosure Practice, replacing the current 75% civil fraud penalty with a 20% accuracy-related penalty for each year in the 6-year disclosure period, based on the IRS news release IR-2025-124.
- The proposed 2026 VDP penalty framework retains the 6-year disclosure period but replaces the 75% civil fraud penalty applied to the single year with the highest understatement with a 20% accuracy-related penalty applied to each of the 6 years, and replaces the 50% willful FBAR penalty with annual inflation-adjusted FBAR penalties per year, based on the IRS Criminal Investigation VDP guidance page.
- Under the proposed 2026 VDP framework, delinquent or amended international information returns carry penalties of up to $10,000 per return per year across the 6-year disclosure period, and taxpayers must make full payment of all taxes, penalties, and interest within 3 months of conditional approval, based on the IRS news release IR-2025-124.
- The TAS’s 77 administrative recommendations made in the 2024 Annual Report to Congress resulted in the IRS agreeing to implement 42 (55%) in full or in part, including key VDP reforms with the willfulness checkbox removal from Form 14457 representing 1 of those adopted changes, and the proposed 20% penalty revision representing the most structurally significant outstanding reform, based on the TAS blog post of June 2025.
IRS Offshore Voluntary Disclosure Programs (OVDP) 2009–2018: Scale and Revenue
- Since the OVDP’s initial launch in 2009, more than 56,000 taxpayers used 1 of the 4 OVDP iterations to comply voluntarily, paying a total of $11.1 billion in back taxes, interest, and penalties before the program closed on September 28, 2018, based on the IRS news release announcing the OVDP closure as cited in Tax Notes.
- The 2009 OVDP ran for approximately 8 months from March to October 2009, during which over 15,000 US taxpayers made voluntary disclosures and the IRS collected an estimated $3.4 billion in overdue taxes, interest, and penalties, based on the published history of the IRS OVDP programs.
- The 2009 and 2011 offshore disclosure programs combined produced 33,000 voluntary disclosures and $4.4 billion collected, based on the IRS-reported figures cited in the published OVDP program history.
- OVDP disclosures peaked in 2011 at approximately 18,000, then declined steadily to only 600 disclosures in 2017, a 97% decline from peak participation, which the IRS cited as a reason to close the program on September 28, 2018, based on the IRS news release cited in Tax Notes.
- As of December 2012, the IRS’s 4 offshore programs had produced more than 39,000 disclosures and over $5.5 billion in revenues, based on GAO report GAO-13-318 on offshore tax evasion published March 2013.
- For the 2009 OVDP, the median account balance among the more than 10,000 cases closed as of the GAO’s review was $570,000, and cases with offshore penalties exceeding $1 million represented approximately 6% of all 2009 OVDP cases but accounted for almost half of all offshore penalties, based on GAO report GAO-13-318.
IRS Streamlined Filing Compliance Procedures: Scale and Outcomes
- The IRS Streamlined Filing Compliance Procedures receive approximately 14,300 annual submissions, compared with approximately 222 annual VDP submissions making the streamlined program the dominant voluntary compliance pathway by a factor of approximately 64 based on Office of Management and Budget statistics cited in a July 2025 analysis.
- The Streamlined Filing Compliance Procedures have helped approximately 65,000 taxpayers come into compliance (in addition to the 56,000+ OVDP participants), while carrying a maximum offshore penalty of 5% of the highest aggregate foreign account balance rather than the VDP’s 75% civil fraud penalty, based on the IRS news release announcing the OVDP closure as cited in Tax Notes.
- Combined, the OVDP and the Streamlined Filing Compliance Procedures together brought more than 100,000 taxpayers into compliance and collected over $10 billion in taxes, interest, and penalties by 2016 with the OVDP producing the large majority of revenue due to its higher willful-penalty structure based on IRS news release IR-2016-137 figures.
IRS Employee Retention Credit (ERC) Voluntary Disclosure Programs: Participation Data
- ERC Voluntary Disclosure Program Round 1 (December 21, 2023 through March 22, 2024) received 2,609 applications from employers who self-identified erroneous ERC claims totaling $1.09 billion in credits disclosed, with participants required to repay 80% of the claimed credit (retaining a 20% discount) with no penalties or interest on the repaid amount, based on the TAS 2024 Annual Report to Congress, Most Serious Problem chapter on ERC.
- ERC Voluntary Disclosure Program Round 2 (August 15, 2024 through November 22, 2024) received only 48 applications a 98% collapse in participation compared with Round 1’s 2,609 applications with terms requiring repayment of 85% of the credit (a 15% discount, versus the prior 20% discount), based on the TAS 2024 Annual Report to Congress.
- The ERC withdrawal program, which allowed employers with unprocessed ERC claims to withdraw without penalty, received 11,832 withdrawal requests; of these, 10,873 had been closed as of September 30, 2024, with 959 still awaiting processing, based on the TAS 2024 Annual Report to Congress, Most Serious Problem chapter on ERC.
- The IRS announced it would send up to 30,000 letters targeting potentially more than $1 billion in additional improper ERC claims in connection with the Round 2 VDP reopening, based on the IRS news release IR-2024-212.
HMRC Cryptoasset Disclosure: Nudge Letters and Voluntary Disclosure Service
- HMRC sent nearly 65,000 crypto tax nudge letters to individuals suspected of undeclared gains in the 2024 to 2025 tax year, up from 27,700 in the 2023 to 2024 tax year a 135% year-on-year increase based on data released under the UK Freedom of Information Act cited by Apex Accountants.
- HM Treasury estimated that the Cryptoasset Reporting Framework (CARF), effective from January 1, 2026, would raise up to £315 million in previously unpaid tax by April 2030 representing tax that would otherwise have gone undetected without the mandatory exchange of transaction data between crypto platforms and HMRC based on the HMRC CARF regulatory impact analysis.
- HMRC’s penalty regime for non-compliance with crypto tax obligations ranges from 10% to 200% of unpaid tax depending on whether the error is deemed careless, deliberate, or deliberately concealed, with an additional £300 per user penalty for reporting cryptoasset service providers (RCASPs) that submit late, inaccurate, incomplete, or unverified CARF reports, based on HMRC guidance and ICAEW summary.
- HMRC recommends use of its Cryptoasset Disclosure Service (CDS) for taxpayers who failed to report crypto income or gains in prior years, with voluntary disclosure before receiving a compliance inquiry typically resulting in penalties at the lower end of HMRC’s 10% to 200% range versus penalties that can reach 100% of unpaid tax or higher when HMRC initiates contact first based on HMRC guidance and commentary from Apex Accountants.
- The CGT annual exemption dropped from £12,300 in 2022 to 2023 to £3,000 in 2024 to 2025 a 76% reduction meaning investors who previously held gains below the reporting threshold now face mandatory self-assessment obligations that, if unmet, create exposure to HMRC’s penalty regime of up to 200% of unpaid tax, based on CIOT commentary.
The Gap Between Intent and Action: Why So Few Disclose Voluntarily
- The IRS simultaneously estimated a $50 billion annual crypto tax gap and identified a 75% non-compliance rate among crypto taxpayers it had identified through exchange records yet the VDP’s 75% civil fraud penalty structure produced an average of fewer than 27 completed cases per year, indicating that the program’s penalty design reduced compliance program participation without meaningfully reducing overall non-compliance, based on TAS 2024 Annual Report to Congress and Deloitte’s analysis of the September 2023 IRS announcement.
- The 2009 OVDP’s 20% offshore penalty produced annualized participation approximately 550 times higher than the post-2018 VDP’s 75% civil fraud penalty a contrast that the TAS cited directly as evidence the current penalty structure is not achieving the program’s intended purpose, based on IRS OVDP historical statistics and TAS 2024 Annual Report.
- Criminal prosecutions related to international activities since 2009 totalled 1,545 taxpayer indictments, of which 671 were for international criminal tax violations, as the IRS confirmed when closing the OVDP in 2018 a prosecution record that was used to motivate voluntary disclosure while the OVDP was active, but which did not sustain post-2018 participation once penalties increased to 75%, based on the IRS OVDP closure news release cited in Tax Notes.
