What Is CRS 2.0 and How Does It Affect Crypto?

CRS 2.0, effective January 1, 2026, brings crypto assets into the global automatic exchange of financial information framework for the first time. Under this updated Common Reporting Standard and its companion Crypto-Asset Reporting Framework (CARF), crypto transactions will become as transparent to tax authorities worldwide as traditional bank accounts — covering exchanges, transfers, balances, and beneficial ownership across 48 participating jurisdictions.

The Original CRS and Its Crypto Gap

The Common Reporting Standard was developed by the OECD and endorsed by the G20 in 2014 as a global framework for the automatic exchange of financial account information between tax authorities. Over 100 jurisdictions have implemented CRS since its launch, enabling governments to detect offshore tax evasion involving traditional financial accounts.

However, the original CRS had a critical gap: it did not cover crypto assets. Because crypto exchanges and wallet providers were not classified as "Reporting Financial Institutions" under the CRS, crypto holdings could exist entirely outside the automatic exchange system. The OECD acknowledged this vulnerability in its 2020 report "Taxing Virtual Currencies," which found that tax compliance rates for crypto income lagged significantly behind traditional investment income.

CARF: The Crypto-Asset Reporting Framework

To close this gap, the OECD published the Crypto-Asset Reporting Framework (CARF) in June 2023 as part of the broader CRS 2.0 amendments. CARF was endorsed by the G20 Finance Ministers and Central Bank Governors at their October 2023 meeting in Marrakech.

Who Must Report Under CARF

CARF defines "Reporting Crypto-Asset Service Providers" (RCASPs) as any entity or individual that, as a business, provides exchange services between crypto assets and fiat currencies, between different crypto assets, or facilitates crypto asset transfers on behalf of clients. This includes:

Centralized exchanges (e.g., Coinbase, Binance, Kraken)
Crypto brokers and dealers
Crypto ATM operators facilitating exchanges above de minimis thresholds
Certain DeFi front-end operators where an identifiable service provider facilitates transactions

An RCASP is subject to reporting obligations in a jurisdiction if it is tax resident there, incorporated or organized there, managed or directed from there, or maintains a regular place of business there.

What Gets Reported

CARF requires reporting of four categories of information for each reportable user:

Exchange transactions: The aggregate gross proceeds and number of transactions for each type of exchange (crypto-to-fiat, crypto-to-crypto), broken down by crypto asset type
Transfer transactions: Reportable retail payment transactions above jurisdiction-specific thresholds
Account balances: Year-end balances for each crypto asset held on the platform, valued in the reporting currency
Beneficial ownership: Identity of the account holder, including name, address, jurisdiction of tax residence, TIN (Tax Identification Number), and date of birth

Notably, CARF captures both retail and institutional activity, with no exemption for small balances or infrequent traders.

48 Jurisdictions: The First Wave

As of the OECD's Joint Statement released in November 2024, 48 jurisdictions committed to implementing CARF and beginning automatic exchanges by 2027 based on 2026 data collection. The participating jurisdictions include:

G7 members: Canada, France, Germany, Italy, Japan, United Kingdom, United States
Major financial centers: Singapore, Hong Kong, Switzerland, Luxembourg, Ireland, Netherlands
Emerging markets: Brazil, India, South Africa, Indonesia, Saudi Arabia, Argentina
Offshore centers: Cayman Islands, British Virgin Islands, Bermuda, Jersey, Guernsey, Isle of Man

The OECD provides a full list of early adopter jurisdictions in its CARF implementation tracker, maintained on the OECD Automatic Exchange Portal.

Timeline: From Data Collection to Exchange

The CARF implementation follows a defined sequence:

2024-2025: Jurisdictions transpose CARF into domestic law and establish reporting infrastructure
January 1, 2026: Data collection begins — RCASPs start gathering reportable information under their local CARF implementation
Early 2027: RCASPs file first CARF reports with their domestic tax authority
September-December 2027: First automatic exchanges between participating tax authorities occur under the Multilateral Competent Authority Agreement (MCAA) on CARF

For US taxpayers, the timeline aligns closely with IRS Form 1099-DA reporting requirements under IRC Section 6045 (as amended by the Infrastructure Investment and Jobs Act), which also begins full cost-basis reporting for centralized exchanges in 2026.

Look-Through Rules: Dual Residency Won't Help

One of CARF's most consequential features is its look-through provisions, designed to prevent individuals from exploiting dual tax residency or nominee arrangements to avoid reporting:

Self-certification requirements: RCASPs must obtain self-certifications from all account holders declaring their tax residence(s). If an account holder claims residence in a non-participating jurisdiction but has indicators suggesting otherwise (address, phone number, power of attorney), the RCASP must investigate.
Multiple residency reporting: If an individual is tax resident in multiple jurisdictions, the RCASP must report to all relevant jurisdictions — not just one.
Entity look-through: For entities holding crypto assets, CARF requires identification and reporting of controlling persons (beneficial owners with 25% or more ownership or control).
Nominee and agent rules: Transactions conducted through nominees, agents, or intermediaries are attributed to the beneficial owner for reporting purposes.

The practical effect: structuring crypto holdings through shell companies, trusts, or multi-jurisdictional arrangements will not prevent CARF reporting. Tax authorities will receive information about the ultimate beneficial owner regardless of the holding structure.

How CRS 2.0 Connects to IRS 1099-DA

For US taxpayers, CARF and the IRS's own crypto reporting regime under Form 1099-DA are complementary but distinct:

Feature	IRS 1099-DA	CRS 2.0 / CARF
Scope	US-based brokers and exchanges	Global (48+ jurisdictions)
Reporting entity	Brokers defined under IRC 6045	RCASPs per OECD definition
Information reported	Gross proceeds, cost basis, gain/loss	Gross proceeds, balances, beneficial ownership
First reporting year	2025 (proceeds), 2026 (cost basis)	2026 (data collection), 2027 (exchange)
Recipient	IRS and taxpayer	Domestic tax authority, then exchanged

The overlap means that a US taxpayer trading on a Cayman Islands-based exchange will now face reporting from both sides: the exchange reports to the Cayman Islands Tax Information Authority under CARF, which then shares with the IRS under the existing FATCA Intergovernmental Agreement and the new CARF MCAA.

Impact on Tax Planning and Offshore Strategies

CARF fundamentally changes the calculus for crypto tax planning strategies that relied on information asymmetry:

Strategies That No Longer Work

Using non-US exchanges to avoid 1099 reporting: CARF ensures your trading activity on foreign exchanges is reported to your home tax authority anyway
Holding crypto in offshore entities: Look-through rules attribute holdings to beneficial owners
Exploiting reporting gaps between jurisdictions: 48 jurisdictions implementing simultaneously eliminates most gap jurisdictions for crypto
Relying on exchange non-compliance: CARF gives tax authorities data about users even if the exchange itself is non-compliant with local tax filings

Legitimate Tax Planning Remains Available

CARF does not eliminate legal tax optimization. Strategies that remain valid include:

Tax-loss harvesting: Selling depreciated assets to offset gains (subject to wash sale rules in applicable jurisdictions)
Long-term holding period benefits: Many jurisdictions offer reduced rates for assets held over 12 months
Specific identification of tax lots: Choosing which lots to sell to minimize tax liability (where permitted by local law)
Retirement account holding: Contributing to tax-advantaged accounts that permit crypto exposure
Charitable donations: Donating appreciated crypto to qualified organizations for a deduction at fair market value

Tools like dTax help investors implement these legitimate strategies by automatically tracking cost basis across all platforms using 8 international methods (including UK Share Pooling and Germany FIFO), identifying tax-loss harvesting opportunities, and generating compliant tax reports regardless of which jurisdictions are involved. dTax also offers a dedicated CARF transaction data export, letting you preview exactly what exchanges will report to tax authorities in all 67 committed jurisdictions.

Preparing for CRS 2.0 and CARF

For Individual Investors

Consolidate your exchange accounts: Know which platforms hold your data and in which jurisdictions they operate
Update your tax residency self-certifications: Ensure your declared tax residence on all platforms is accurate and current
Maintain complete transaction records: Do not rely solely on exchange-provided reports — export and independently verify your transaction history
Report proactively: File amended returns for prior years if needed, before CARF data exchanges begin — voluntary disclosure programs typically carry lower penalties than audit-triggered assessments
Use automated tracking tools: dTax imports from 23+ exchange CSV formats and blockchain indexers, supports 8 international cost basis methods (FIFO, LIFO, HIFO, Specific ID, Germany FIFO, PMPA, Total Average, UK Share Pooling), and offers CARF transaction data export — ensuring no transactions are missed and your records match what authorities will receive

For Tax Professionals

Audit client disclosures: Verify that clients have disclosed all crypto holdings, including those on foreign platforms
Update engagement letters: Specifically include crypto asset reporting obligations under CARF
Monitor jurisdiction-specific implementation: CARF thresholds and reporting details may vary slightly by jurisdiction
Plan for 2027 data matching: Tax authorities will begin matching CARF data against filed returns — identify and resolve discrepancies now
Use CARF-ready tools: dTax's CPA dashboard includes CARF transaction data export, multi-client management, and support for all 8 international cost basis methods required across the 67 committed jurisdictions

Frequently Asked Questions

Will my government know about my crypto?

Yes. Starting in 2026, any crypto exchange or service provider subject to CARF in any of the 48 participating jurisdictions will collect and report your transaction data, account balances, and identity information to their local tax authority. That authority will then automatically share this information with your country of tax residence. By 2027, your government will receive detailed data about your crypto activity on foreign platforms — comparable to what it already receives about your foreign bank accounts under the existing CRS.

Can I avoid CRS 2.0 reporting?

Not through legitimate means. CARF's look-through rules, self-certification requirements, and broad definition of reporting entities are specifically designed to prevent avoidance. Using non-participating jurisdictions, nominee structures, or decentralized platforms does not guarantee avoidance — and attempting to circumvent CARF may constitute tax evasion, which carries criminal penalties in most jurisdictions. The most effective strategy is accurate, proactive reporting.

How does CRS 2.0 differ from 1099-DA?

IRS Form 1099-DA applies only to US-based crypto brokers reporting to the IRS and US taxpayers. CRS 2.0/CARF is a global framework covering 48+ jurisdictions with automatic cross-border information exchange. The key difference is scope: 1099-DA tells the IRS what you did on US platforms, while CARF tells your home tax authority what you did on platforms worldwide. For US taxpayers, both systems will operate simultaneously, creating overlapping but complementary reporting that covers domestic and international crypto activity.
