Crypto Tax Reporting Rules 2026: How CARF, DAC8 and Form 1099-DA Are Reshaping Compliance

Crypto tax reporting rules 2026 represent the most significant change to digital asset compliance since exchanges first began issuing tax forms. Tax authorities in dozens of countries are now receiving standardized transaction data directly from exchanges, custodians, and brokers, rather than relying solely on self-reported filings. The compliance landscape now looks closer to traditional banking, where third-party reporting is the default.

What changed in global crypto tax reporting during 2026?

Global crypto tax reporting shifted from optional disclosure to automated data-sharing in 2026. The OECD’s CARF went live on January 1, national regimes like the UK’s cryptoasset rules followed, and the US began its first full Form 1099-DA filing season.

Three developments define the year. First, the OECD’s Crypto-Asset Reporting Framework (CARF) began active data collection on January 1, 2026, in an initial wave of jurisdictions, according to Crowdfund Insider and Finextra, which both put the first wave at 48 nations. Second, the European Union folded CARF into binding law through the DAC8 directive, and the UK ran its own parallel regulations. Third, 2026 is the first US tax-filing season with Form 1099-DA broker reporting fully in effect, per CNBC and crypto.news. These three tracks are not synchronized — different timelines, data, and taxpayer populations — so country-by-country awareness now matters more than any single global rule.

What is the OECD’s Crypto-Asset Reporting Framework and which countries use it?

The Crypto-Asset Reporting Framework (CARF) is an OECD standard requiring crypto exchanges, custodians, and wallet providers to collect user data and report transactions to tax authorities, who then exchange records across borders automatically.

According to Finextra and Crowdfund Insider, 48 jurisdictions began active CARF data collection on January 1, 2026. A broader group — cited by Blockpit as over 50 jurisdictions, and by OECD Global Forum monitoring as approaching 76 committed members — has signaled intent to join later waves. Rollout sequencing places the EU, UK, Canada, South Korea, and Japan in the first exchange wave, with domestic reports due in 2027. A second wave — reportedly Switzerland, Singapore, the UAE, Hong Kong, and Turkey — targets 2028, while the US has committed to CARF exchanges only from 2029, a gap that matters for any business with US crypto exposure.

CARF obligations sit with crypto-asset service providers, not individual holders. Exchanges, brokers, and wallet providers must collect and transmit user data — name, address, date of birth, tax residency, and tax identification number — alongside transaction records covering crypto-to-crypto trades, crypto-to-fiat conversions, and wallet transfers, per Blockpit’s summary of the framework. The obligation also reaches platforms based outside the EU, such as Binance or Bybit, if they hold an operating license in a participating country like Malta, Lithuania, or Germany.

How does the EU’s DAC8 directive apply CARF in practice?

DAC8 is the European Union’s legal vehicle for adopting CARF, binding all EU member states to collect and report crypto-asset service provider data starting January 1, 2026, with first domestic reports due in 2027.

DAC8 does not create a separate standard; it transposes CARF’s due-diligence and reporting rules into EU administrative cooperation law, per the European Commission’s DAC8 page. A provider registered in one member state reports once, and the data is shared automatically with every other EU tax authority and, once cross-border exchange begins, with non-EU CARF partners. Any EU-licensed exchange, custody service, or crypto payment processor should treat DAC8 due-diligence obligations as already live, since data collection began in January even though first reports are not filed until 2027.

What does the UK’s new cryptoasset reporting regime require from HMRC?

The UK’s Reporting Cryptoasset Service Providers Regulations 2025 require exchanges to collect users’ name, address, date of birth, tax residency, and tax ID from January 1, 2026, with first reports due to HMRC by May 31, 2027.

According to TaxAssist Accountants and BDO, UK reporting providers must submit records of conversions, exchanges, wallet-to-wallet transfers, stablecoin transactions, and card payments alongside onboarding data. HMRC still treats most cryptoassets as property, so disposals are typically subject to Capital Gains Tax rather than income tax, with income tax applying to earnings such as staking rewards in specific cases. Individuals still file through Self Assessment; the new rules change how HMRC verifies filings, not the underlying tax treatment. Data on non-UK residents will be exchanged with their home jurisdictions once cross-border CARF exchange begins.

How does US Form 1099-DA change crypto tax reporting in 2026?

Form 1099-DA requires US crypto brokers to report gross proceeds from digital asset sales directly to the IRS and taxpayers, making 2026 the first full filing season under mandatory broker-level reporting for the 2025 tax year.

Brokers, including exchanges like Coinbase, began reporting gross proceeds from crypto sales for transactions from January 1, 2025 onward, with 1099-DA forms furnished to recipients by February 17, 2026, per CoinLedger and TokenTax. Cost-basis reporting was voluntary for the 2025 tax year, which means many of the first 1099-DA forms taxpayers received only showed proceeds, not gain or loss — taxpayers still had to calculate and substantiate their own cost basis. Starting with 2026 transactions, brokers must begin reporting cost basis as well, tightening the gap between what a broker reports and what a taxpayer files. Anyone reconciling multiple wallets and exchanges against a 1099-DA should treat this transition year carefully; our crypto tax record-keeping and reporting guide covers the documentation practices that make that reconciliation manageable, and a deeper walkthrough of the form itself is available in our guide to Form 1099-DA.

How are national crypto tax rules diverging in 2026?

Reporting frameworks are converging around CARF, but tax rates and enforcement stay national: India kept a flat 30% tax with 1% TDS, while the US and UK apply capital gains rates with new broker-reporting obligations layered on top.

India confirmed in February 2026 that it will maintain its 30% tax on virtual digital asset income and 1% tax-deducted-at-source (TDS) on transactions above the statutory threshold for 2026-27, according to KuCoin News. Losses on one crypto asset still cannot offset gains on another, and full transaction-level reporting under India’s Income Tax Act 2025 took effect April 1, 2026, with penalties for exchanges that misreport. The table below compares the reporting and tax posture of four major jurisdictions covered in this article, drawn from the sources cited throughout.

What compliance risks should crypto holders watch for under the new reporting rules?

The main risk is a mismatch between broker-reported figures and self-filed returns, since IRS automated matching and blockchain analytics firms like Chainalysis and Elliptic can flag discrepancies that trigger notices, audits, or penalty assessments.

This risk is highest during transition years, and 2026 is one. In the US, 1099-DA cost-basis reporting is only now becoming mandatory, so a taxpayer who treats an incomplete 2025-year form as the full picture — rather than reconciling it against wallet-level records — can under- or over-report gains without realizing it. Cross-border holders face a parallel risk: CARF data collection already runs in the UK and EU even though first exchanges land in 2027, so today’s activity sits inside the reporting window regardless of when paperwork moves between authorities. Our guide to cross-border crypto tax residency and double taxation covers how overlapping jurisdictions typically get resolved.

How should businesses and investors prepare for 2026 reporting requirements?

Preparation means reconciling wallet-level cost basis before broker reports arrive, centralizing transaction records across every exchange and wallet used, and confirming which CARF or domestic filing deadlines apply to each jurisdiction where assets are held.

Three steps follow from the changes above. First, reconcile cost basis at the wallet level now rather than waiting on brokers, since the IRS’s per-wallet basis method (replacing the older universal pooling approach) already applies to transactions from January 1, 2025 onward. Second, anyone using multiple exchanges — particularly non-US platforms licensed in CARF-participating countries — should assume transaction data is already being collected, even before cross-border exchange begins in 2027. Third, map out which regime applies where: a UK-based holder on an EU-licensed exchange is inside CARF today; a US-only holder is inside 1099-DA but outside CARF’s exchange network until 2029. Crypto tax software such as Koinly, CoinLedger, and CoinTracker has expanded per-wallet, per-jurisdiction reconciliation tools to address this shift toward continuous record-keeping over year-end calculation.

Frequently Asked Questions

Does CARF replace FATCA or CRS reporting for crypto assets?

No. CARF is a separate, crypto-specific standard that runs alongside the existing Common Reporting Standard (CRS) and, for US persons, FATCA. Some jurisdictions are updating CRS in parallel specifically because crypto assets fell outside its original scope.

Will exchanges report crypto transactions from before 2026 under CARF?

Reported CARF rules generally apply prospectively from each jurisdiction’s start date rather than retroactively. Tax authorities can still request older records through separate audit or investigation powers, independent of CARF’s standard reporting cycle.

What happens if a crypto exchange does not comply with CARF or DAC8?

Non-compliant crypto-asset service providers face regulatory penalties under each jurisdiction’s implementing law, and in the EU can risk their operating license. Users of a non-compliant platform may still be individually liable for accurate self-reporting regardless of what the platform submits.

Do decentralized exchanges and self-custody wallets fall under CARF?

CARF’s reporting duty is placed on crypto-asset service providers such as centralized exchanges, brokers, and custodians. Purely self-custodied wallets and non-custodial protocols without an identifiable service provider generally sit outside that direct reporting obligation, though the tax liability on the underlying transactions is unchanged.

When will US crypto data actually be shared internationally under CARF?

The US has committed to beginning CARF exchanges in 2029, later than the EU, UK, Canada, South Korea, and Japan, which are in the first wave. Until then, US crypto tax compliance runs primarily through Form 1099-DA and existing IRS enforcement channels rather than CARF’s cross-border network.

Does Form 1099-DA cover NFT and DeFi transactions?

Form 1099-DA is designed to cover digital asset sales processed through brokers, which can include certain NFT marketplace transactions where a broker is involved. DeFi protocols without a clear broker intermediary raise more complex questions that remain an active area of IRS guidance.
