Tax-loss harvesting has moved from a niche strategy among sophisticated investors to a central pillar of mainstream crypto tax planning. In 2026, the convergence of elevated crypto market volatility, the first mandatory Form 1099-DA reporting season in the United States, tightening broker cost basis rules, and escalating international enforcement has transformed how investors approach realised losses. The strategy, which involves selling a crypto asset at a loss to offset capital gains and reduce taxable income, benefits from a structural advantage that no equivalent exists for equities: the wash sale rule, which prohibits repurchasing the same security within 30 days, does not yet apply to cryptocurrency under US tax law. That legal asymmetry is drawing increasing attention from both investors and legislators.
At KoinX, we help investors across jurisdictions navigate the complexity of crypto tax reporting, and the data we aggregate consistently shows that tax-loss harvesting is one of the most frequently misunderstood and underutilised strategies available to crypto holders. The statistics compiled in this article document the scale of the opportunity, the compliance backdrop that shapes it, the investor behaviours driving adoption, and the legislative risk that may ultimately close the wash sale exemption.
The article proceeds through: scope and methodology, headline statistics, the US legal and regulatory framework, investor compliance and noncompliance data, international context, and the legislative landscape. Every statistic is sourced directly from government filings, academic working papers, multilateral bodies, or first-party exchange disclosures.
Scope and Methodology
This article was compiled against a strict primary source standard. Every statistic was required to originate from an organisation that produced the data itself: government and regulatory bodies (IRS, US Treasury, US Senate, Taxpayer Advocate Service), academic institutions and multilateral research bodies (NBER, BIS, IMF), or first-party exchange disclosures (Coinbase, CoinTracker). Aggregator blogs, news summaries, and secondary sources were excluded regardless of prominence.
A two-year recency window was enforced for all statistics. Data older than two years was excluded unless no more recent equivalent from a primary source exists, in which case it is flagged with its original year. The geographic scope of this article is primarily the United States, given that the wash sale rule exemption and the IRS enforcement and legislative landscape provide the richest verifiable primary-source data for tax-loss harvesting specifically. Supplementary data from Norway, the OECD framework, and IMF research provide international comparison on compliance rates and tax revenue at stake.
Statistical integrity was maintained by assigning one metric per bullet, one source per bullet, and linking every source to the specific report, filing, dataset, or document rather than to a homepage. No statistics were combined, synthesised, or inferred. Material limitations include: no authoritative aggregate figure exists for total US or global crypto tax-loss harvesting volumes, as this data is not separately collected or published by the IRS or any equivalent body; academic studies use proxy indicators such as wash trading patterns on exchanges to estimate harvesting activity.
Crypto Tax-Loss Harvesting in 2026: The Headline Numbers
- Under current US tax law, capital losses from cryptocurrency sales offset capital gains dollar-for-dollar, and net capital losses of up to $3,000 ($1,500 if married filing separately) may be deducted against ordinary income per year, with remaining losses carried forward indefinitely, based on IRS Topic No. 409 Capital Gains and Losses.
- Estimated US crypto tax gap attributable to unreported digital asset transactions is at least $50 billion annually, cited in a 2023 US Senate letter from Senators Warren, Casey, Blumenthal, and Sanders to Treasury and the IRS urging implementation of crypto broker reporting rules.
- The nonpartisan Joint Committee on Taxation estimated that the digital asset broker reporting provisions of the Infrastructure Investment and Jobs Act would raise almost $28 billion in federal revenue over 10 years, based on the US Treasury Department press release accompanying the proposed broker regulations issued August 25, 2023.
- 88% of Norwegian cryptocurrency holders failed to declare their holdings on their tax returns in 2021, even though exchanges shared identifiable trading data with tax authorities, based on NBER Working Paper No. 32865 (2024) by Meling, Mogstad, and Vestre using de-anonymised crypto trading data linked to individual Norwegian tax returns.
- 80% of investors trading on Norwegian domestic crypto exchanges failed to declare their cryptocurrencies, despite those exchanges sharing identifiable trading data with the Norwegian Tax Administration, based on NBER Working Paper No. 32865 (2024) by Meling, Mogstad, and Vestre.
- Increased IRS tax scrutiny empirically caused US-regulated crypto exchanges to exhibit a significantly greater amount of wash trading, which the researchers use as a proxy for tax-loss harvesting activity, based on NBER Working Paper No. 30716 (2022) by Cong, Landsman, Maydew, and Rabetti analysing 34 major crypto exchanges from Kaiko data.
- An estimated 73 to 81% of retail Bitcoin investors over the period August 2015 to December 2022 across 95 countries likely lost money on their initial investment, based on BIS Working Paper No. 1049 (2022) by Auer, Cornelli, Doerr, Frost, and Gambacorta analysing crypto exchange app data.
- The IMF estimated that a 20% capital gains tax on globally accrued crypto gains would have generated approximately $100 billion worldwide in 2021, assuming one-third of those gains were realised, based on IMF Working Paper No. 2023/144 Taxing Cryptocurrencies by Baer, De Mooij, Hebous, and Keen.
- The Senator Lummis digital asset tax bill introduced July 3, 2025 was estimated by the Congressional Joint Committee on Taxation to generate approximately $600 million in net revenue during the 2025 to 2034 budget window, driven in part by a proposed 30-day wash sale rule for digital assets, based on the official press release from Senator Lummis’s office.
The US Tax-Loss Harvesting Framework: IRS Rules and Capital Loss Mechanics
- The IRS classifies cryptocurrency as property rather than a security, which means the wash sale rule under Section 1091 of the Internal Revenue Code, which prohibits claiming a loss when the same or substantially identical security is repurchased within 30 days before or after the sale, does not currently apply to crypto assets, based on IRS Notice 2014-21 and subsequent IRS guidance.
- Capital losses from crypto disposals must be reported on Form 8949, Sales and Other Dispositions of Capital Assets, with totals summarised on Schedule D (Form 1040), Capital Gains and Losses, based on IRS instructions for Schedule D (Form 1040) for tax year 2025.
- Net capital losses that exceed capital gains may reduce ordinary income by up to $3,000 per year ($1,500 if married filing separately), with all remaining net losses carried forward indefinitely to future tax years, based on IRS Topic No. 409, Capital Gains and Losses.
- Short-term crypto capital gains on assets held for one year or less are taxed as ordinary income at federal rates ranging from 10% to 37% for the 2025 tax year, based on KPMG’s 2025 tax considerations publication for cryptocurrency investors.
- Long-term crypto capital gains on assets held for more than one year are taxed at preferential federal rates of 0%, 15%, or 20% depending on taxable income for the 2025 tax year, based on KPMG’s 2025 tax considerations publication for cryptocurrency investors.
- For the 2025 tax year, the 0% long-term capital gains tax rate applies to single filers with taxable income below $48,350, based on IRS Topic No. 409, Capital Gains and Losses.
- The Tax Cuts and Jobs Act of 2017 disallows miscellaneous itemised deductions for the tax years 2018 through 2025, meaning ordinary losses from a cryptocurrency investment that becomes completely worthless are not currently deductible as a miscellaneous itemised deduction, based on the IRS Taxpayer Advocate Service tax tip on deducting digital asset investment losses.
- Revenue Procedure 2024-28, effective January 1, 2025, requires taxpayers to use wallet-by-wallet cost basis tracking rather than pooled universal cost basis, which directly affects which loss lots are available for harvesting at any given time, based on the official revenue procedure published by the IRS.
- For 2025 transactions reported in 2026, custodial brokers are required to report gross proceeds only on Form 1099-DA; cost basis reporting for covered assets does not become mandatory until transactions occurring on or after January 1, 2026, meaning many 1099-DA forms issued in 2026 will show proceeds but blank cost basis fields, based on the IRS instructions for Form 1099-DA (2025).
Investor Compliance, Knowledge Gaps, and Noncompliance Rates
- Conditional on holding cryptocurrencies, 88% of Norwegian crypto holders failed to declare their holdings in tax returns in 2021, a noncompliance rate higher than rates documented for self-employment income (45%), foreign earned income (45%), and real estate abroad (71%) in comparable Scandinavian studies, based on NBER Working Paper No. 32865 (2024) by Meling, Mogstad, and Vestre.
- 6.9% of Norwegians held some cryptocurrency in 2021, and of those holders, 88% failed to declare their cryptocurrency on their tax returns, meaning 6% of the Norwegian population were crypto tax noncompliers in that year, based on NBER Working Paper No. 32865 (2024) and a summary published by the Washington Center for Equitable Growth in November 2024.
- The average value of tax evasion across all cryptocurrency noncompliers in Norway was estimated at between $200 and $1,087 per person per year, a modest amount suggesting enforcement strategies need to be either well-targeted or very cheap to be cost-effective, based on NBER Working Paper No. 32865 (2024) by Meling, Mogstad, and Vestre.
- 74% of surveyed US crypto users are aware that crypto is taxable, and 65% have previously reported crypto activity on their taxes, based on the 2026 Crypto Tax Readiness Report by CoinTracker and Coinbase (survey of 3,000 US crypto users, conducted September to October 2025).
- Only 35% of surveyed US crypto users have actually adjusted their cost basis despite being aware that cost basis adjustments may be required when transferring assets across platforms, based on the 2026 Crypto Tax Readiness Report by CoinTracker and Coinbase (survey of 3,000 US crypto users).
- 64% of surveyed US crypto users are unaware of upcoming rule changes to digital asset tax reporting, based on the 2026 Crypto Tax Readiness Report by CoinTracker and Coinbase (survey of 3,000 US crypto users).
- 78% of US crypto users still file their taxes using general tax software, and 52% use an accountant, while more than one-third are actively seeking AI assistance with the tax process, based on the 2026 Crypto Tax Readiness Report by CoinTracker and Coinbase (survey of 3,000 US crypto users).
- 83% of US crypto users surveyed in late 2025 also hold investments outside crypto including stocks, bonds, and real estate, indicating crypto capital losses can frequently be applied against gains from a broader diversified portfolio, based on the 2026 Crypto Tax Readiness Report by CoinTracker and Coinbase (survey of 3,000 US crypto users).
Tax-Loss Harvesting Behaviour: Academic and Exchange-Level Evidence
- Increased IRS tax scrutiny empirically led domestic US crypto traders to increase tax-loss harvesting as a legal alternative to noncompliance, and US-regulated exchanges exhibited a significantly greater amount of wash trading compared with international peers following increases in enforcement, based on NBER Working Paper No. 30716 (2022) by Cong, Landsman, Maydew, and Rabetti analysing trading data from 34 major crypto exchanges.
- Tax-loss harvesting activity on US-regulated exchanges was more pronounced during market downturns and at year-ends, consistent with the hypothesis that investors strategically time loss realisation before December 31 to capture the current-year deduction, based on NBER Working Paper No. 30716 (2022) by Cong, Landsman, Maydew, and Rabetti.
- An estimated 73 to 81% of retail Bitcoin investors over August 2015 to December 2022 likely lost money on their Bitcoin investments across 95 countries, creating the pool of investors with harvestable losses, based on BIS Working Paper No. 1049 (2022) by Auer, Cornelli, Doerr, Frost, and Gambacorta.
- The median retail investor in BIS’s 95-country study lost approximately 48% of their total invested amount in Bitcoin by December 2022, based on BIS Bulletin No. 69 (2023) by Cornelli, Doerr, Frost, and Gambacorta on crypto shocks and retail losses.
- Over $1.8 trillion of crypto market value dissolved after prices peaked in November 2021, with over $450 billion lost during the Terra/Luna collapse in May 2022 and another $200 billion in the wake of the FTX bankruptcy in November 2022, creating the largest single-period pool of harvestable losses in crypto’s history, based on BIS Bulletin No. 69 (2023) by Cornelli, Doerr, Frost, and Gambacorta.
- Larger and more sophisticated Bitcoin investors (whale wallets) reduced their holdings during periods of sharp price decline following the Terra/Luna and FTX events, while smaller retail investors bought, suggesting sophisticated market participants are more likely to implement loss-realisation strategies, based on BIS Bulletin No. 69 (2023).
- About 40% of new crypto exchange app users globally between 2015 and 2022 were men under 35, the demographic group most commonly identified as risk-seeking, based on BIS Working Paper No. 1049 (2022) by Auer, Cornelli, Doerr, Frost, and Gambacorta across 95 countries.
- Among US crypto investor households tracked from 2014 to 2022, approximately 38% of household-quarters experienced a quarterly loss in crypto wealth, creating recurring opportunities for tax-loss harvesting across the investor lifecycle, based on NBER Working Paper No. 31445 (2023) examining the effects of cryptocurrency wealth on household consumption.
International Compliance and Revenue Potential Statistics
- The IMF estimated that a 20% accrual-based capital gains tax on global crypto gains would have generated approximately $323 billion in 2021, representing roughly 12% of global corporate income tax revenue, based on IMF Working Paper No. 2023/144 Taxing Cryptocurrencies by Baer, De Mooij, Hebous, and Keen.
- If one-third of 2021 global crypto gains were realised and taxed at 20%, estimated tax revenue would still have been approximately $100 billion worldwide, based on IMF Working Paper No. 2023/144 by Baer, De Mooij, Hebous, and Keen.
- The IMF identified EU crypto capital gains tax revenue potentially foregone in 2020 at approximately EUR 850 to 900 million based on analysis of transaction volumes and assumed rates, comparing to approximately EUR 12 billion in capital gains tax revenue in the UK alone in the same period, based on IMF Working Paper No. 2023/144 by Baer, De Mooij, Hebous, and Keen.
- Norway saw 73,000 crypto declarations in 2024, a 30% increase year-over-year, with declared holdings valued at $4 billion and $550 million in declared gains, following Norwegian tax enforcement initiatives, based on reporting in Bitcoin Ethereum News citing Norwegian tax authority data, October 2025.
- From January 1, 2026, crypto custodians and exchange operators in Norway are required to report transaction details through third-party channels to the Norwegian tax authority, based on reporting in Bitcoin Ethereum News citing Norwegian tax enforcement announcements, October 2025.
- As of November 2025, 75 jurisdictions have committed to implement the OECD Crypto-Asset Reporting Framework (CARF), with first international exchanges of tax data expected in 2027, which will narrow the window for undetected tax-loss harvesting transactions across borders, based on the 2025 OECD CARF Monitoring and Implementation Update.
Legislative Landscape: Wash Sale Rule and Proposed Changes
- The Lummis-Gillibrand Responsible Financial Innovation Act introduced in the 118th Congress (Senate Bill S.2281) included Section 805, Loss from Wash Sales of Crypto Assets, which would apply a 30-day wash sale rule to digital assets, making it the first major bipartisan legislative proposal to close the crypto wash sale exemption, based on the full text of S.2281 published on Congress.gov.
- The Senator Lummis digital asset tax bill introduced July 3, 2025 (S.2207 in the 119th Congress) includes a 30-day wash sale rule for digital assets that would disallow losses on crypto assets sold and repurchased within a 30-day period, based on the official Senator Lummis press release on the legislation.
- The Senator Lummis digital asset tax bill introduced July 3, 2025 includes a $300 de minimis exclusion for individual digital asset transaction gains and losses, with a $5,000 inflation-adjusted annual cap, based on the official Senator Lummis press release.
- The Protecting Americans from Tax Hikes (PARITY) Act discussion draft released December 20, 2025, circulated by Representatives Max Miller and Steven Horsford, includes a wash sale rule provision for digital assets and reserves a section for constructive sale rules under Section 1259 of the Internal Revenue Code, based on BDO’s January 2026 analysis of the proposed legislation.
- The CLARITY Act, a sweeping digital asset regulatory reform bill, passed the US House of Representatives in a 294 to 134 vote on July 17, 2025, and is being considered by the Senate Agriculture Committee and Senate Banking Committee, and may be combined with digital asset tax reform legislation, based on BDO’s January 2026 analysis of the legislative process.
- The Biden administration’s fiscal year 2024 budget proposal called for applying wash sale rules to digital assets, a provision the Congressional Budget Office estimated would generate $9 billion between fiscal years 2024 and 2028, or $23.5 billion over 10 years, based on Baker Institute’s April 2023 analysis of the budget proposal citing CBO estimates.
Broker Reporting and Cost Basis Statistics Affecting Loss Harvesting
- For the 2025 tax year, brokers are not required to report cost basis on Form 1099-DA, meaning many investors must reconstruct their own cost basis and loss lots independently to correctly implement tax-loss harvesting, based on the IRS instructions for Form 1099-DA (2025).
- Beginning with 2026 transactions (reported in 2027), brokers must report both gross proceeds and adjusted cost basis for covered digital assets on Form 1099-DA, which will create standardised cost basis records relevant to future loss calculations, based on the IRS final regulations on digital asset broker reporting published July 2024.
- Coinbase will report stablecoin transactions to the IRS only in aggregated form where they exceed $10,000 per the IRS mandate for the 2025 tax year, based on Coinbase’s official tax change summary published February 2026.
- The IRS digital asset question is required on Forms 1040, 1040-SR, 1040-NR, 1041, 1065, 1120, and 1120-S, requiring all taxpayers regardless of crypto activity to answer the question under penalty of perjury, based on IRS newsroom guidance on digital asset reporting requirements.
- Investors who realise losses on crypto assets held as investments report those losses on Form 8949 and summarise them on Schedule D, the same forms used for securities and other capital assets, based on IRS Taxpayer Advocate Service guidance on deducting digital asset investment losses.
