Crypto tax reporting standards, explained
This is general information, not legal, tax, or financial advice. The relevant regulators are named below. Verify the current position with a qualified local professional and the official regulator before acting.
Tax authorities are rolling out automatic reporting of crypto account data. The main standards are the OECD Crypto Asset Reporting Framework, the European Union directive known as DAC8, and in the United States broker reporting on Form 1099 DA. Data collection began on 1 January 2026 for the OECD framework and DAC8, with the first cross border information exchanges due by 30 September 2027, as of April 2026.
Why reporting standards are arriving now
For years crypto sat outside the automatic information sharing that already covered bank accounts. Tax authorities have now closed that gap with rules that require crypto platforms to identify their users and report transactions, then to exchange that information across borders. These are reporting rules. They do not create a new tax, but they make it far easier for a tax authority to see crypto activity, so accurate self reporting matters more than before (as of April 2026).
The OECD Crypto Asset Reporting Framework
The OECD Crypto Asset Reporting Framework, known as CARF, is the global standard for the automatic exchange of crypto account information between tax authorities. The OECD published the framework in 2023. More than seventy jurisdictions have announced an intention to exchange information under it, with the first exchanges expected in 2027 or 2028 (as of April 2026). The framework is administered nationally by each participating country's tax authority.
The European Union directive DAC8
DAC8 is the European Union law that puts the OECD framework into effect across member states. It was adopted on 17 October 2023, member states were required to transpose it into national law by 31 December 2025, and its provisions apply from 1 January 2026. The first exchange of information, covering the 2026 reporting year, is due by 30 September 2027 (as of April 2026). The relevant authority is each member state's tax administration, coordinated through the European Commission.
United States broker reporting on Form 1099 DA
In the United States the Internal Revenue Service requires custodial brokers, such as centralised exchanges, to report digital asset transactions on the new broker form, Form 1099 DA. Brokers must report gross proceeds for transactions on or after 1 January 2025, and must add cost basis reporting for covered digital assets acquired after 2025, for transactions on or after 1 January 2026 (as of April 2026). A separate rule that would have extended reporting to certain decentralised finance front end services was overturned by a Congressional Review Act resolution signed into law on 10 April 2025, so those front end services are not covered.
What gets reported and what it means for you
Under these standards platforms typically collect your identity and tax residence and report account details, gross proceeds, and in some cases cost basis to the tax authority. The practical takeaway is to keep complete records of acquisitions, disposals, and transfers, and to reconcile what a platform reports with your own filing. This is general information and not tax advice. Confirm how each rule applies to you with your national tax authority and a qualified professional before filing.

Frequently asked questions
Do crypto exchanges report to tax authorities?
Increasingly yes. Under the OECD framework, the European Union DAC8 directive, and United States broker rules, platforms collect user information and report transactions to tax authorities. Data collection began on 1 January 2026 in the European Union and under the OECD framework (as of April 2026).
Does crypto tax reporting create a new tax?
No. These are reporting standards, not new taxes. They make existing tax obligations easier for authorities to verify, which is why accurate self reporting and good records matter.
When do the first crypto information exchanges happen?
Under DAC8 and the OECD framework the first exchanges, covering the 2026 reporting year, are due by 30 September 2027 (as of April 2026). Some jurisdictions begin in 2027 and others in 2028.
What is Form 1099 DA?
Form 1099 DA is the United States broker form for digital asset transactions. Custodial brokers report gross proceeds for transactions from 1 January 2025 and add cost basis for covered assets from 1 January 2026 (as of April 2026).
Are decentralised finance platforms covered by United States reporting?
A rule that would have extended Form 1099 DA reporting to certain decentralised finance front end services was overturned by a resolution signed into law on 10 April 2025, so those services are not subject to that requirement. Custodial brokers remain covered.
Reporting rules and start dates are being implemented unevenly across jurisdictions and can change. Confirm the current obligations and deadlines with your national tax authority and a qualified professional before filing.
