What DAC8 is

DAC8 is an EU directive on cooperation between tax authorities. It extends their automatic exchange of information to crypto-assets, based on the OECD's Crypto-Asset Reporting Framework. Crypto exchanges and other providers serving EU residents collect and report data about their users.

Timeline

  • 1 January 2026: providers start collecting data on the transactions of their EU users.
  • 2027: providers report the 2026 data to their national tax authority.
  • By 30 September 2027: tax authorities exchange the first data, about 2026, with each other.

What is reported

Per coin, the totals of what you bought and sold against euros or other crypto and the value of your transfers, together with details that identify you and the provider.

What it means in Belgium

Your 2026 gains go on the tax return you file in 2027, and the tax office will be able to compare it with what exchanges report. Complete exchange files and your own records make it easier to explain differences, for example coins you moved between your own wallets.
