A draft bill shows the EU plans to force crypto firms to give tax authorities details of their clients' holdings, which can be shared within the 27-nation bloc

Context & Ripple Effects
This draft bill is the tax leg of an architecture Brussels has been assembling since 2021, when the Commission first proposed forcing companies that transfer Bitcoin and other crypto-assets to collect sender and recipient details (collect sender and recipient details). In late 2022 it hardened into a requirement that digital asset providers report EU-based clients' transactions to tax authorities starting January 1, 2026 (report transactions to tax authorities from 2026); today's move extends that visibility from flows to stock — what clients actually hold.
The timing matters because the compliance stack beneath it is already locked in: lawmakers provisionally agreed in 2022 on verified-identity rules for transfers between regulated wallets, and last year the Council and Parliament reached a deal on the Anti-Money Laundering Regulation obliging all crypto companies to run user due diligence (AML Regulation user due diligence deal). With draft plans also circulating to shift authorization of all crypto businesses from national regulators to ESMA (ESMA centralizing crypto authorization), holdings disclosure slots into a regime where the reporting plumbing will soon be mandatory anyway.
First-order effects
- Crypto firms serving EU clients would owe tax authorities a new class of data — client holdings, not just transactions — shared automatically across all 27 member states rather than filed jurisdiction by jurisdiction.
- Clients of those firms lose practical anonymity of balances within the bloc: whatever a firm reports on transactions from 2026 would now extend to what each account holds at any point.
Second-order effects
- Firms must extend their reporting infrastructure beyond the transaction pipelines built for the 2026 requirement, raising fixed compliance costs that fall hardest on smaller exchanges and custodians already absorbing the AML due-diligence obligations.
- Offshore or non-EU venues become relatively more attractive to holders who want balances outside the reporting net — the classic pressure point when one bloc tightens while others lag.
Third-order effects
- If the pattern holds, the EU treats digital assets as fully reportable financial accounts end to end — identity, transfers, transactions, and balances — collapsing the distinction between how tax authorities see crypto and how they see banked money.
- The combined effect of tax reporting, AML due diligence, and centralized ESMA authorization points to consolidation around fully authorized firms, with activity migrating either into the regulated perimeter or to jurisdictions that opt out.
The trend: The EU is assembling a full-stack supervisory regime for crypto — sender details, transaction reporting, due diligence, and now holdings — steadily closing the visibility gap between digital assets and traditional financial accounts.
