MiCA, DAC8, and crypto tax reporting

MiCA does not change how crypto is taxed; it is silent on tax. The EU layer people confuse it with is DAC8, a separate tax-reporting directive that makes crypto-asset service providers report user data from 2026. A plain explainer of who reports what, and how it connects to your MiCA status.

MiCA is not tax law

MiCA regulates the licensing, conduct, and supervision of crypto-asset service providers. It says nothing about how gains, income, or transactions are taxed. Taxation stays a national competence, so each EU member state applies its own rates and rules. The EU-wide layer people confuse with MiCA is DAC8, which is about reporting, not rates.

Informational only, not tax or legal advice. Tax treatment is national and fact-specific; consult a qualified adviser.

What DAC8 is

DAC8 is Council Directive (EU) 2023/2226, the eighth update to the EU’s Directive on Administrative Cooperation. It extends automatic exchange of tax information to crypto-assets and aligns the EU with the OECD’s Crypto-Asset Reporting Framework (CARF). It applies from 1 January 2026, with the first reporting following for that period.

  • Who reports: reporting crypto-asset service providers (RCASPs), a tax concept that overlaps with, but is not identical to, MiCA CASPs. A MiCA authorisation does not by itself settle your DAC8 status.
  • What is reported: identifying information on reportable users and aggregated details of their crypto-asset transactions (acquisitions, disposals, exchanges, and transfers).
  • To whom: the national tax authority, which exchanges it with other member states’ authorities.
  • Due diligence: RCASPs must collect and validate user tax-residence and identity information, similar in spirit to CRS for financial accounts.

How it connects to MiCA

Different triggers

MiCA status turns on providing regulated services in the EU. DAC8 status turns on being a reporting crypto-asset service provider for tax purposes. Confirm both separately.

Shared data plumbing

The KYC and customer data you build for MiCA and AML feed DAC8 due diligence. Design onboarding once so it supports licensing, the travel rule, and tax reporting.

CARF beyond the EU

CARF is being adopted by many non-EU jurisdictions too, so a global platform faces parallel reporting obligations, not just DAC8.

Not a rate change

None of this changes a user’s tax bill. It changes what authorities can see. National rules still decide what is taxable and at what rate.
