What is DAC8?
DAC8 (Directive on Administrative Cooperation in Direct Taxation) is a European regulation that extends tax reporting obligations to crypto-assets and crypto service providers.
From 1 January 2027, all EU-regulated crypto providers will be required to communicate certain client information and crypto-related activities to the relevant tax authorities.
This reporting will be backdated to activities from 1 January 2026.
How does DAC8 apply to Deblock?
Deblock is a regulated European crypto provider and fully complies with DAC8. What we report is strictly limited by how Deblock operates.
Only crypto buy, sell and exchanges made through Deblock are reportable.
These reports are shared only with the relevant tax authorities, as required by law. At the same time, Deblock is a self-custody service. This means:
You are the sole owner and manager of your wallet
Deblock has no access to your funds
Deblock has no visibility into your wallet balance
Deblock has no insight into external wallets or activities outside the platform
Because of this, Deblock does not report:
Crypto wallet balances
Assets held in self-custody
Crypto transfers between wallets (incoming or outgoing), whether to your own wallet or to other wallets
Transactions carried out outside Deblock
If Deblock can’t see it, Deblock can’t report it.
Deblock does not communicate customer crypto balances. DAC8 does not require this, and as a self-custody platform, Deblock has no technical ability to access or report this data.
What does this mean for you?
You stay fully in control of your crypto
Your self-custody wallet remains private
Only crypto buy, sell and exchange transactions made through Deblock are reportable
Wallet-to-wallet transfers, incoming or outgoing, are not reported
You remain responsible for declaring your crypto gains to the relevant tax authorities
Deblock’s position on privacy
Deblock was built as a compliant, privacy-first platform.
While respecting regulatory requirements, we strongly believe that:
Self-custody is a fundamental principle
Reporting wallet balances or wallet-to-wallet transfers would create serious privacy and security risks
Protecting user data is essential in today’s environment
We will continue to stand firm in protecting the privacy of assets held in self-custody.
