CARF Reporting Jurisdiction Checker
Find out when your country will implement CARF reporting requirements and what you need to know about crypto tax reporting.
Quick Takeaways
- The OECD’s Crypto‑Asset Reporting Framework (CARF) extends the Common Reporting Standard to cover crypto‑assets.
- 67 jurisdictions have pledged to adopt CARF by 2028, with the EU’s DAC8 leading the rollout.
- Reporting Crypto‑Asset Service Providers (RCASPs) must collect detailed transaction data and send it to the taxpayer’s residence country each year.
- Implementation hinges on new XML standards released in October 2024 and on national legislation by the end of 2025.
- Compliance costs are rising for exchanges, brokers, and tax administrations, but the system promises stronger global tax transparency.
When you hear the phrase automatic exchange of crypto tax information, you might picture a secret back‑room where governments swap spreadsheets. In reality, it’s a coordinated, technology‑driven process built on a set of international rules. The core of that system is the Crypto-Asset Reporting Framework (CARF), an OECD‑led initiative that forces crypto‑exchanges, wallets and other service providers to report who owns what, where, and for how much.
Why the World Needed a New Framework
Traditional tax‑information exchange works well for banks and listed securities because the assets sit in clearly defined accounts. Crypto‑assets live on blockchains, move instantly across borders, and often involve pseudonymous wallets. That made it hard for tax authorities to know whether a trader earned capital gains or paid the appropriate tax.
The Organisation for Economic Co‑operation and Development (OECD) recognized this gap after a G20 mandate in 2022. Their answer was CARF, which sits on top of the existing Common Reporting Standard (CRS) but adds new fields that capture blockchain‑specific details-transaction hashes, wallet addresses, and the nature of the digital asset.
How CARF Works: The Reporting Chain
The process can be boiled down to three steps:
- Data collection by RCASPs. Reporting Crypto‑Asset Service Providers (RCASPs) must gather information about every customer who trades, earns staking rewards, or holds crypto on their platform. The data set includes name, tax‑identification number, country of tax residence, and a full transaction log for the reporting year.
- Submission to the local tax authority. Using the OECD‑approved XML format, the RCASP sends the file to its national tax administration. The XML User Guide, published in October 2024, defines every tag-so a field for “crypto‑asset type” (e.g., Bitcoin, ERC‑20 token) and a field for “exchange‑rate at time of transaction.”
- Automatic exchange with the taxpayer’s residence country. The home‑country tax authority receives the file through the same XML channel and automatically integrates it into the taxpayer’s return‑processing system.
Because the exchange happens electronically and on a set schedule (usually annually), there’s no need for bilateral requests or manual data pulls.
Key Players and Their Roles
Several entities shape the ecosystem:
- European Union DAC8 - the EU’s legal instrument that transposes CARF into national law for all 27 member states. DAC8 must be in force by 31 December 2025, with reporting starting 1 January 2026.
- United States Internal Revenue Service (IRS) - will require non‑U.S. brokers to report U.S. customer data and will reciprocate by sharing U.S.‑source crypto information with other CARF jurisdictions.
- G20 - provided the political backing that pushed the OECD to act.
- National tax administrations - draft legislation, build data‑processing pipelines, and enforce compliance.
- Crypto exchanges, wallet providers, and custodians - develop the IT systems to capture and format the data.
Implementation Timeline Across Major Jurisdictions
| Jurisdiction | Legal Instrument | Reporting Start Year |
|---|---|---|
| European Union | DAC8 Directive | 2026 |
| United States | IRS CARF Guidance (2025) | 2027 |
| United Kingdom | HMRC CARF Regulations | 2027 |
| Australia | ATO Crypto Reporting Rule | 2027 |
| Singapore | IRAS CARF Framework | 2027 |
| New Zealand | IRD Crypto‑Asset Reporting Act | 2027 |
| Canada | CRA Implementation Notice | 2028 |
| Japan | National Tax Agency (NTA) CARF Directive | 2028 |
The table shows the earliest reporting years, but all jurisdictions must pass legislation by the end of 2025 to meet the global deadline.
What It Means for Crypto‑Businesses
For an exchange, the biggest hurdle is building a pipeline that can pull every on‑chain transaction, map it to a customer, and output the required XML file. That requires:
- Secure KYC data storage that can be linked to wallet addresses.
- Real‑time blockchain analytics to tag each trade with the correct asset code and market value.
- Automated validation to flag missing or inconsistent fields before the file is sent.
Many mid‑size platforms are already partnering with third‑party compliance vendors, but the push to go live by 2026 means budgets are being set now.
Challenges and Criticisms
Even with a solid technical standard, several pain points remain:
- Data quality. Pseudonymous wallets can belong to multiple users, making the “who owns what” link fuzzy.
- Cross‑border legal differences. Some countries still classify certain tokens as securities, others as commodities, which affects the tax treatment and the fields required in the XML.
- Infrastructure readiness. Smaller tax administrations lack the IT capacity to process large XML feeds, potentially creating backlogs.
- Competitive concerns. Jurisdictions that marketed a low‑tax environment may lose trading volume to places with stricter reporting.
Experts suggest that uniform definitions of “crypto‑asset” and a shared sandbox for testing XML exchanges will lessen these frictions.
Potential Market Impact
When a large share of the market becomes transparent, two trends are likely:
- Increased compliance costs may push some high‑frequency traders toward jurisdictions that haven’t signed up yet, at least temporarily.
- Legitimate investors will experience less scrutiny from tax authorities, as the data will flow automatically rather than through manual audits.
Overall liquidity is expected to stay stable because the reporting burden spreads evenly across all major exchanges.
Where the Framework May Evolve
CARF is designed as a living standard. The OECD plans to revisit the XML schema every two years, adding fields for emerging assets like non‑fungible tokens (NFTs) and tokenized securities. There is also talk of integrating real‑time reporting for high‑frequency trading, but that would require a significant upgrade to the current annual‑exchange model.
Next Steps for Stakeholders
If you run a crypto service, here’s a short checklist:
- Confirm your jurisdiction’s legal instrument (DAC8, IRS guidance, etc.) and the compliance deadline.
- Map every customer’s KYC record to at least one blockchain address.
- Choose a compliance vendor that supports the 2024 XML User Guide format.
- Run a pilot export for the 2025 tax year to catch data‑quality issues early.
- Set up a secure channel to transmit the XML file to your national tax authority.
For taxpayers, the key takeaway is that you’ll soon see a line item on your tax return for foreign crypto‑exchange activity, even if you never filed a form yourself. Keep good records, and consider professional advice if you trade across multiple platforms.
Frequently Asked Questions
What is the Crypto‑Asset Reporting Framework (CARF)?
CARF is an OECD‑created set of rules that expands the Common Reporting Standard to include crypto‑assets. It obliges reporting crypto‑asset service providers to collect detailed transaction data and automatically share it with the taxpayer’s country of residence.
Which jurisdictions are required to follow CARF?
As of 2025, 67 jurisdictions-including all EU member states, the United States, the United Kingdom, Australia, Singapore, New Zealand and Canada-have pledged to implement CARF. Each must pass national legislation by the end of 2025, with reporting generally starting between 2026 and 2028.
What data do Reporting Crypto‑Asset Service Providers have to submit?
The XML file must contain the customer’s name, tax‑ID, residence country, wallet addresses, each transaction’s date, crypto‑asset type, amount, and the fiat value at the time of the trade. Additional fields cover staking rewards, airdrops and other income‑generating events.
How will this affect individual crypto traders?
Traders can expect their foreign crypto activity to appear automatically on their tax return. Keeping accurate records will still be important, but the burden of reporting to the tax authority shifts to the exchange or wallet provider.
When does the first reporting year begin?
The earliest reporting year is 2026 for EU member states under DAC8. The United States and most other jurisdictions plan to start receiving reports for the 2027 tax year, with full rollout by 2028.

This is actually a huge step forward for global tax fairness. I've been tracking CARF since the OECD draft came out, and the XML schema is way more robust than I expected. Exchanges are gonna hate the compliance costs, but honestly? It's about time. No more hiding behind pseudonymous wallets when you made $200k in crypto gains last year. The system's not perfect, but it's a damn good start.

This is just the government's way of tracking EVERYTHING. 🤡 They don't care about taxes-they care about CONTROL. Next thing you know, they'll be scanning your blockchain history like it's a surveillance camera. And don't even get me started on the IRS... they'll audit you for a 0.001 BTC trade you forgot to report in 2021. #FreeCrypto #TheyreWatching

Honestly, I'm shocked this took until 2024 to happen. The whole crypto space has been a regulatory free-for-all, and now we're playing catch-up with a 300-page XML spec? The fact that Japan and Canada are only implementing in 2028 is frankly embarrassing. I mean, if you can't even get your tax infrastructure up to speed by now, maybe you shouldn't be in the game. Also, 'crypto-asset type' as a field? That's like calling a Tesla a 'vehicle type'. We're all adults here.

I can't believe this is real... they're going to link my wallet to my SSN?!?!?! This is the beginning of the END. The government is building a digital leash for every single crypto user, and they're calling it 'transparency'-but it's just surveillance with a tax stamp! I've seen the XML schema-there's a field for 'staking rewards' and 'airdrops'... they know EVERYTHING. I'm not even gonna touch crypto again. I'm moving to a country that doesn't have a passport. I'm going to live in a cabin in the woods with my solar panels and my goats. They can't track goats. 🐐😭

Hey, if you're running a small exchange or just trading on the side, don't panic. You’ve got time. Start with mapping your KYC to wallets-that’s the biggest hurdle. There are legit vendors out there that handle the XML formatting for under $5k/year. I helped a friend set it up last month. It’s not glamorous, but it’s doable. Just don’t wait until December 2025. Trust me, you’ll regret it.

It's fascinating how the EU is leading this with DAC8 while the U.S. drags its feet. Honestly, it's embarrassing. The IRS still thinks a 1099 form is enough for crypto. The fact that we're lagging behind Singapore and Australia? Pathetic. And don't even get me started on how the U.S. expects reciprocity while refusing to implement real-time reporting. It's like asking someone to share their dessert while you're still chewing your own.

CARF? More like CARF-UP! 😂 The EU thinks they're the world’s tax police now? Ireland doesn't need this. We’ve got 12.5% corporate tax for a reason. Why should we help the U.S. and UK suck the life out of crypto innovation? If they want data, they can pay for it. We’re not your data slaves. And why is the XML spec so bloated? I’ve seen better formatting in my 2007 Excel spreadsheet. 🇮🇪🔥
