Bitcoin sits at the intersection of two fast-moving forces in 2026: an asset whose on-chain holder distribution is better documented than almost any investment class in history, and a tax enforcement apparatus that is only now catching up to the scale of activity. With approximately 106 million people globally estimated to own Bitcoin, the IRS has shifted from ad-hoc enforcement to systematic data collection through Form 1099-DA, John Doe summonses, and blockchain analytics partnerships. The gap between the number of people who own Bitcoin and the number who accurately report their capital gains remains one of the most documented compliance shortfalls in the U.S. tax system.

At KoinX, we track how Bitcoin holder data, capital gains obligations, and IRS enforcement intersect because that intersection is precisely where the compliance burden falls hardest.

The statistics in this article are sourced exclusively from primary institutional data: IRS publications and Criminal Investigation annual reports, TIGTA audit findings, SEC filings, on-chain data from Glassnode, CoinShares institutional research, River Learning, and first-party corporate disclosures. Every bullet contains at least 1 explicit numerical value and no statistic is duplicated across sections.

Scope and Methodology

Statistics are sourced from primary documents including IRS Criminal Investigation annual reports, TIGTA audit reports, SEC Edgar filings from Strategy (formerly MicroStrategy), CoinShares 13F institutional research, River.com holder data, Glassnode on-chain analytics, the July 2024 TIGTA virtual currency compliance audit, the IRS-CI FY2025 Annual Report, and primary court filings covering John Doe summonses. A two-year recency window applies for survey and market data; IRS enforcement data is drawn from the most recent fiscal year available.

Geographic scope is global for holder distribution and U.S.-centric for tax enforcement.

Bitcoin Holder Distribution: Global and On-Chain

An estimated 106 million people worldwide owned Bitcoin in 2024, representing approximately 1.29% of the global population of 8.2 billion, based on Bitbo holder estimates and UN World Population Prospects 2024 data as compiled by CoinLedger.
Of all 460 million Bitcoin addresses that have ever held a balance above 0.0 BTC, 288 million currently hold no Bitcoin at all, 172 million are active, and only approximately 25 million are believed to be economically active wallets belonging to private individuals, based on Bitbo’s 2024 holder address analysis citing Chainalysis on-chain data.
Over 56 million addresses held a positive BTC balance as of mid-2025, based on on-chain data reported by CoinLedger in its 2025 Bitcoin lost-coin research.
Just 83 wallets held between 10,000 and 100,000 BTC as of mid-2025, controlling 11.2% of the total Bitcoin supply, while only 4 wallets held over 100,000 BTC each, together accounting for 3.23% of all coins, based on CoinLedger’s 2025 Bitcoin distribution analysis.
The top 100 Bitcoin addresses held approximately 15% of the total supply, and addresses holding over 100 BTC controlled approximately 61% of all circulating Bitcoin, based on CCN’s March 2025 analysis of the 10 biggest Bitcoin holders.
Bitcoin’s illiquid supply reached a record 14.3 million BTC in late August 2025, equivalent to over 72% of the approximately 19.9 million BTC in circulation, as coins held without spending history accumulated at the fastest rate in Bitcoin’s history, based on Glassnode data reported by CoinDesk in September 2025.
Bitcoin’s illiquid supply grew by more than 422,000 BTC between January 1 and September 2025, driven by entities holding BTC for over 7 years without selling, based on Glassnode on-chain data reported by TradingView in September 2025.
Long-term holders control approximately 74% of circulating Bitcoin supply, while only approximately 3.5 million BTC are actively traded, with 86% of all trading volume driven by large investors, based on CoinLedger’s mid-2025 Bitcoin supply and lost-coin analysis.

Institutional and Government Bitcoin Holdings

Satoshi Nakamoto’s wallets hold an estimated 968,452 BTC spread across approximately 20,000 addresses, all of which have remained untouched since Bitcoin’s early years, representing a significant portion of the supply that will never enter taxable circulation, based on River.com’s December 2025 Bitcoin holder analysis.
Strategy (formerly MicroStrategy) held 640,031 BTC as of January 2026, purchased at a total cost of approximately $47.4 billion at an average price of $73,983 per coin, making it the largest publicly listed corporate Bitcoin holder, based on The Block’s January 2026 reporting citing Michael Saylor’s disclosures.
Strategy adopted ASU 2023-08 fair-value accounting for its Bitcoin holdings on January 1, 2025, which produced a $12.7 billion uplift to retained earnings at adoption, while also recording a $5.9 billion unrealized fair-value loss in Q1 2025 as Bitcoin prices moved, based on Strategy’s SEC 8-K filing of April 28, 2025.
U.S. Treasury clarified in January 2026 that corporations may exclude unrealized digital asset gains when calculating the 15% corporate alternative minimum tax, which applies to firms with over $1 billion in adjusted financial statement income; Strategy confirmed it does not expect CAMT liability on its Bitcoin mark-to-market gains as a result, based on The Block’s January 2026 reporting.
ETFs and other investment funds collectively held approximately 1.5 million BTC, equal to 7% of total Bitcoin supply as of late 2025, with BlackRock’s iShares Bitcoin Trust holding approximately 771,000 BTC as the largest single ETF holder, based on River.com’s Bitcoin holder analysis updated December 2025.
BlackRock’s IBIT reached $70 billion in AUM by end of 2025, representing approximately 59% of all U.S. spot Bitcoin ETF assets, while Fidelity’s FBTC reached $17 billion and Grayscale’s GBTC held $15.5 billion, based on The Block’s 2026 Institutional Crypto Outlook published December 2025.
Institutional investors filing 13F disclosures held $21.2 billion in U.S. Bitcoin ETF positions at the end of Q1 2025, down 23% from $27.4 billion in Q4 2024, representing a 22.9% share of total U.S. Bitcoin ETF AUM, based on CoinShares’ Q1 2025 institutional 13F filing analysis.
Governments globally held an estimated 305,000 BTC equal to 1.50% of total supply as of late 2025, led by the United States, which is the largest sovereign Bitcoin holder following law enforcement seizures, with Bhutan holding 9,969 BTC and El Salvador holding 6,274 BTC, based on River.com’s 2025 Bitcoin holder analysis.
Corporate strategic reserves and ETF issuers combined held 2.88 million BTC in September 2025, a 30% increase from 2.24 million BTC at the start of 2025, based on Glassnode data reported by TradingView.

Bitcoin Capital Gains Tax Rates and Reporting Obligations

Short-term capital gains on Bitcoin held for 365 days or fewer are taxed as ordinary income at rates ranging from 10% to 37% for tax year 2025, while long-term gains on Bitcoin held for more than one year are taxed at 0%, 15%, or 20% depending on taxable income, based on IRS Schedule D instructions for 2025.
The 0% long-term capital gains threshold for a single taxpayer in 2025 applies to taxable income up to $48,350, meaning Bitcoin holders with income below that level owe no capital gains tax on long-term BTC disposals, based on Koinly’s 2025 U.S. crypto tax guide citing IRS rate tables.
Coinbase expected to issue over 4 million Form 1099-DA statements for tax year 2025, reporting gross proceeds to both taxpayers and the IRS; Bitcoin purchased and held in the same custodial account on or after January 1, 2026 is classified as “covered,” triggering mandatory cost basis reporting by brokers starting with 2026 tax year transactions, based on IRS final digital asset broker regulations published July 9, 2024.
For tax year 2025, brokers must report gross proceeds on Form 1099-DA but are not required to include cost basis, with de minimis thresholds set at $10,000 for qualified stablecoin transactions and $600 for NFTs, below which no 1099-DA is required, based on IRS final broker regulations published July 2024.
Accuracy-related penalties for underreporting Bitcoin gains equal 20% of the understated tax amount, failure-to-file penalties can reach 25% of unpaid taxes, fraud penalties can reach 75% for willful evasion, and criminal prosecution carries up to $100,000 in fines and 5 years in prison, based on IRS guidance summarized in the 2025 cryptocurrency tax reporting resource by Instead.
Bitcoin represented nearly 62% of total virtual currency market capitalization at over $1.3 trillion as of June 11, 2024, while Bitcoin and Ether together accounted for over 82% of the market capitalization among the 10 largest virtual currencies, based on the July 2024 TIGTA virtual currency tax compliance audit report.

IRS Bitcoin and Digital Asset Enforcement Actions

IRS Criminal Investigation investigated 390 cases involving virtual currency or digital assets during fiscal years 2018 to 2023, of which 224 cases were completed with a recommendation for prosecution, based on the TIGTA Virtual Currency Tax Compliance Enforcement audit report dated July 10, 2024.
The IRS Automated Underreporter program reviewed 1,895 returns with a digital asset component for tax year 2020, of which 948 of the 1,315 closed cases resulted in additional tax assessments averaging $28,832 per case, based on the TIGTA July 2024 virtual currency compliance audit report.
From fiscal year 2020 onward, IRS Small Business/Self-Employed civil examiners conducted 365,000 total taxpayer examinations, of which only 1,144, equal to 0.31%, included a review of digital asset activity, a coverage rate TIGTA characterized as “negligible,” based on the July 2024 TIGTA virtual currency compliance audit report.
IRS Criminal Investigation identified over $10.6 billion in financial crimes in FY2025, a figure that includes tax and non-tax offenses, and referred 2,043 cases for prosecution while seizing more than $800 million in assets and returning $100 million to crime victims, based on the IRS-CI FY2025 Annual Report published December 11, 2025.
IRS Criminal Investigation dedicated nearly 64% of its investigative time to tax crimes in FY2025, with cyber-related cases resulting in defendants sentenced to an average of 63 months in prison, based on the IRS-CI FY2025 Annual Report published December 11, 2025.
For tax years 2013 to 2015, IRS internal data found only 800 to 900 taxpayers per year filed returns with a property description related to Bitcoin or virtual currency, even though Coinbase alone had serviced more than 5.9 million customers and processed over $6 billion in transactions during that same period, based on the IRS petition for a John Doe summons against SFOX filed in U.S. federal court.
IRS letters sent to over 10,000 virtual currency holders beginning July 26, 2019 resulted in more than $17.6 million in assessments as taxpayers filed amended returns for unreported Bitcoin and virtual currency transactions covering tax years 2013 through 2019, based on the IRS petition for a John Doe summons against SFOX.
IRS CI SAR Review Teams operating in 94 federal judicial districts seized assets valued at $385.4 million between FY2023 and FY2025, based on the IRS-CI BSA metrics report published March 2025.

John Doe Summonses and Exchange Data Collection

A court ordered Coinbase to turn over data for approximately 13,000 customers who had transacted more than $20,000 in any single year between 2013 and 2015, following the IRS’s 2016 John Doe summons against the exchange, based on court filings cited by CountDeFi’s 2026 IRS crypto tracking analysis.
The IRS’s May 2021 John Doe summons against Kraken obtained records for all U.S. users who transacted the equivalent of $20,000 or more in any year between 2016 and 2020, including account registration data, full transaction history, IP addresses, and linked bank account numbers, based on McDonald Hopkins legal analysis of the Kraken summons enforcement.
A new IRS crypto audit form introduced in early 2026 includes a pre-printed checklist of over 100 cryptocurrency exchanges and requires audited taxpayers to certify under penalty of perjury whether they used each listed platform, going back multiple years beyond the audit period, based on Gordon Law Group’s March 2026 analysis of the Historical Digital Assets Form.
Approximately 6.8 million Form 1040 filers reported virtual currency transactions for tax year 2021, representing 4% of all 1040 filers, up from approximately 2.3 million filers representing 1.5% of all filers for tax year 2020, based on IRS data cited in the December 2023 TIGTA evaluation of IRS digital asset monitoring.
During FY2022 to FY2024, IRS Criminal Investigation used Bank Secrecy Act data to identify $21.1 billion in fraud tied to tax and financial crimes, seize $8.2 billion in assets, and obtain $1.4 billion in restitution for crime victims, with 87.3% of cases recommended for prosecution having a related BSA filing and a 97.3% conviction rate, based on the IRS-CI FY2024 BSA metrics report published March 28, 2025.
The IRS Whistleblower Office paid awards totaling $123.5 million in FY2024, based on $474.7 million in collected proceeds attributable to whistleblower information, a 39% increase over FY2023, demonstrating that the agency increasingly uses third-party informants to identify crypto tax noncompliance, based on the IRS FY2024 Whistleblower Office Annual Report.
Asia-Pacific received the largest volume of on-chain cryptocurrency value globally, with a 69% year-over-year increase between June 2024 and June 2025, while North American monthly transfer volumes exceeded $2 trillion with approximately $16 trillion transferred between January and July 2025, based on the Chainalysis 2025 Geography of Crypto Report.
The IRS stopped 99% of fraudulent returns identified during the 2025 filing season, preventing issuance of more than $2 billion in fraudulent refunds, while online account users exceeded 51 million (an increase of 12 million from the prior year), based on the TIGTA October 2025 assessment of major IRS challenges for FY2026.

Bitcoin Supply Structure and Its Tax Implications

As of August 2025, approximately 19.88 million BTC had been mined, representing 94.8% of the fixed 21 million supply cap, with an estimated 2.3 million to 4 million BTC permanently lost (11% to 18% of total supply), based on CoinLedger’s 2025 Bitcoin supply analysis.
About 82.3% of all circulating Bitcoin supply was in profit as of October 2025, based on Glassnode data reported by The Block, indicating that a large majority of all Bitcoin holders who sell in 2025 or 2026 will owe capital gains tax on their disposals.
Bitcoin’s all-time high price exceeded $120,000 in July 2025, up from $0.06 in 2010, meaning long-term holders who acquired Bitcoin at any point before mid-2025 face unrealized gains ranging from hundreds to millions of percent, creating potentially very large taxable events upon disposal, based on CoinLedger’s 2025 Bitcoin supply research.
Bitcoin processed an average of 504,508 daily transactions in October 2025, generating an average daily on-chain volume of $28.46 billion, each transaction representing a potential taxable event for U.S. holders who sold or exchanged BTC, based on PANews analysis of on-chain Bitcoin metrics as of October 2025.
Fidelity Digital Assets projects that if current accumulation trends persist, nearly 42% of all Bitcoin, approximately 8.3 million BTC, will be classified as illiquid by Q2 2032, compressing the pool of tradeable supply and concentrating future taxable disposal events among a smaller group of active market participants, based on Fidelity’s illiquid supply analysis cited by The Block in October 2025.
The number of distinct virtual currency types grew 420% between April 2020 and July 2023, from 5,000 to over 26,000, massively expanding the universe of digital assets requiring per-asset, per-wallet capital gains tracking beyond Bitcoin alone, based on the TIGTA July 2024 virtual currency compliance audit report.
75 jurisdictions made a political commitment to implement the OECD Crypto-Asset Reporting Framework as of November 2025, up from 48 in November 2023, expanding the reach of automatic cross-border crypto tax data exchange and increasing the likelihood that unreported Bitcoin gains held in overseas wallets will be identified by the IRS, based on the OECD 2025 CARF Monitoring and Implementation Update.
Bitcoin and crypto-related illicit activity totalled at least $154 billion in 2025, a 162% increase from a revised $57.2 billion in 2024, intensifying the IRS’s focus on tracing Bitcoin flows through analytics partners, based on the Chainalysis 2026 Crypto Crime Report published January 2026.
