In 2026, crypto tax software accuracy has become a regulatory and financial flashpoint. The arrival of IRS Form 1099-DA for the 2025 tax year, mandatory wallet-by-wallet cost basis tracking under Revenue Procedure 2024-28, and the UK’s Cryptoasset Reporting Framework (CARF), which came into effect on 1 January 2026, have together transformed the compliance landscape in ways that make software accuracy genuinely consequential. Where errors in cost basis calculations or transaction classification once floated largely undetected, they now collide directly with machine-readable third-party data that tax authorities in multiple jurisdictions already hold.

At KoinX, we work directly at the intersection of these developments, helping investors and tax professionals automate crypto tax reporting in an environment where data accuracy determines whether a return matches what the IRS or HMRC already knows. The statistics assembled in this article reflect what that pressure looks like across enforcement, software usage, investor behavior, and compliance outcomes, grounded entirely in primary-source data from government agencies, regulatory bodies, and first-party platform disclosures published within the past two years.

The article is organized into thematic sections covering the US gross tax gap and digital asset underreporting context, IRS criminal enforcement outcomes, TIGTA audit findings on digital asset civil compliance, cost basis reporting mechanics and IRS regulatory milestones, global compliance and regulatory framework data, and the enforcement footprint of major exchanges.

Scope and Methodology

This article draws exclusively on statistics sourced from government agencies, regulatory inspectors general, academic and policy research institutions, legislative bodies, and first-party platform disclosures. All sources were subject to a primary source test: the data must originate from the organization cited, and the URL must resolve to the specific report, filing, dataset, or regulatory document rather than a homepage or aggregator.

A strict two-year recency window was applied, with figures from the October 2023 to April 2026 period prioritized. Where a statistic originates from a study or filing published before that window, the original year is retained and flagged. Figures from secondary sources, news aggregators, blog posts, or market research firms without disclosed primary methodology were excluded in all cases.

Geographic coverage spans the United States, the United Kingdom, and global regulatory frameworks, reflecting the jurisdictions for which the most verifiable primary-source enforcement and compliance data is currently available.

The Numbers That Define Crypto Tax Software Accuracy in 2026

The IRS voluntary compliance rate for tax year 2022 was projected at 85.0%, meaning approximately 15% of taxes owed were not paid voluntarily and on time, based on the 2024 IRS Tax Gap Projections publication.
The Joint Committee on Taxation projected that mandatory digital asset broker reporting enacted via the 2021 Infrastructure Investment and Jobs Act would raise nearly $28 billion in tax revenue over a decade, based on the official estimate cited in the 2024 IRS final regulations release.
Approximately 1% of all US tax returns in tax year 2020 reported any sales of crypto, well below the 10% to 20% of American adults estimated by survey evidence to have held crypto at that time, based on analysis cited in the 2023 IMF Working Paper on taxing cryptocurrencies.
The IRS digital asset question appeared on 7 federal tax forms for tax year 2023 Forms 1040, 1040-SR, 1040-NR, 1041, 1065, 1120, and 1120-S based on IRS newsroom guidance for that filing year.
An IRS review covering tax years 2020 through 2022 found that approximately 25% of crypto investors voluntarily complied with their tax obligations, indicating that approximately 75% of crypto investors may not have been compliant, according to a 2025 analysis citing IRS internal review data.
The UK HM Treasury estimated that the Cryptoasset Reporting Framework (CARF) could raise up to £315 million in unpaid tax by April 2030, based on the HMRC CARF regulatory impact analysis.
HMRC sent nearly 65,000 crypto tax nudge letters to individuals suspected of undeclared crypto gains in the 2024 to 2025 tax year, up from 27,700 letters in the 2023 to 2024 tax year a 135% increase based on data released under the Freedom of Information Act.
Coinbase received 10,707 government and law enforcement information requests in the period October 2023 through September 2024, an 18% decrease from the prior year’s 13,079 requests, according to Coinbase’s Transparency Report 2024.
In 2016, the IRS issued a John Doe Summons compelling Coinbase to hand over customer transaction data, resulting in more than 10,000 Coinbase customers being contacted with IRS warning letters for transactions of $20,000 or more.
The IMF’s 2023 Working Paper estimated that if all cryptocurrency transactions were subject to VAT, potential recoverable revenue would fall between $47.4 billion and $118.5 billion depending on collection feasibility.

IRS Enforcement and Audit Statistics for Digital Assets

Cost Basis Reporting: Scale of the Accuracy Problem

Only 1,144 out of 365,391 total taxpayer examinations conducted by the IRS Small Business and Self-Employed Division between fiscal years 2020 and 2023 included a review of digital asset activity, representing 0.31% of all examinations, according to the 2024 TIGTA audit report on virtual currency tax compliance.
The number of virtual currency types grew from 5,000 in April 2020 to over 26,000 by July 2023, a 420% increase, substantially expanding the range of assets for which cost basis must be accurately tracked, according to the 2024 TIGTA report.
If a US crypto investor cannot locate original purchase records and fails to establish cost basis, the IRS treats the cost basis as $0, making 100% of gross proceeds taxable as a capital gain, based on IRS guidance and Revenue Procedure 2024-28.
The 2 most dominant virtual currencies had a combined total market capitalization of over $1.7 trillion as of June 11, 2024, with Bitcoin representing nearly 62% of that figure at over $1.3 trillion, based on market data cited in the TIGTA 2024 virtual currency compliance report.
For tax year 2025, Form 1099-DA reports gross proceeds only and excludes cost basis data, leaving 100% of cost basis calculation responsibility on individual taxpayers and exposing them fully to cost basis errors on their returns, based on IRS guidance on the digital assets page.

TIGTA Findings on Digital Asset Civil Compliance Gaps

The TIGTA July 2024 audit (Report Number 2024-300-030) found that IRS civil examination coverage of digital asset activity represented only 0.31% of all examinations between fiscal years 2020 and 2023, with 1,144 digital-asset-related examinations conducted out of 365,391 total a coverage level TIGTA characterized as insignificant.

IMF and Global Crypto Tax Revenue Statistics

The IMF 2023 Working Paper estimated that the maximum potential taxable EU resident capital gains from Bitcoin transactions in 2020 was approximately EUR 850 to 900 million, representing an upper-bound estimate of potential crypto capital gains tax evasion across EU jurisdictions in that year.
The IMF’s 2023 Working Paper found that approximately 1% of all US returns in tax year 2020 reported crypto sales well below the 10% to 20% of American adults survey evidence suggested held crypto implying a substantial self-reporting gap in crypto capital gains disclosure.
The IMF-FSB 2023 Synthesis Paper noted that even supervised institutions required to report crypto-related activities to tax authorities may not comply with existing regulations, compounding the compliance gap that automated tools are designed to close, based on the joint IMF-FSB policy paper published September 2023.

Exchange Reporting and Enforcement Request Statistics

Coinbase received 12,716 law enforcement and government information requests during the period October 2024 through September 2025, a 19% increase over the prior year’s 10,707 requests, with 53% of all requests originating from outside the United States, according to Coinbase’s Transparency Report 2025.

Frank Ahlgren’s total unreported crypto gains across the 3 investigation years (2017, 2018, and 2019) exceeded $3,000,000, with his agreed tax loss exceeding $1,000,000, based on IRS-CI case records and court filings.
