Circle Warns EU $23B Crypto Tax Estimate May Be Overstated

Patrick Hansen, Circle’s EU strategy and policy lead, warned that the European Commission’s estimate of up to $23 billion in crypto tax revenue for the 2028–2034 budget cycle may be overstated, arguing that proposed transaction levies could push trading to decentralized finance protocols, self‑custody wallets and platforms outside the EU.

The warning responds to a leaked Commission services paper that models two tax approaches. One option would impose a 0.1% levy on the value of crypto transactions. The paper estimates that if crypto‑asset service providers act as collection and reporting points, the levy could raise about $3.5 billion to $4.7 billion a year. A second option would tax realized capital gains on crypto and is estimated to yield $1.2 billion to $2.8 billion annually. The Commission combined the two models to arrive at a figure close to $23 billion across the seven‑year budget period, while noting the totals depend on market volatility and other factors.

The paper says stablecoins used for payments would likely be excluded from the transaction levy and that capital gains rules generally would not apply to dollar‑pegged tokens because they show minimal price movement. The Commission’s calculations assume current trading patterns concentrated on centralized venues inside the EU and use data that remain incomplete.

Hansen identified three structural weaknesses in the Commission’s modeling. He said complete and reliable reporting under DAC8, the EU’s crypto tax reporting framework for authorities, will not be widely available until 2027, leaving early revenue estimates based on partial inputs. He noted any new EU tax measure would need unanimous approval by the Council of the European Union and a harmonized EU tax base. Hansen also highlighted the likely behavioral response from crypto users: if centralized exchanges serve as collection points, users could move trading to self‑custody wallets, DeFi protocols or non‑EU platforms, reducing taxable volumes.

Hansen warned that a transaction‑based crypto tax would likely accelerate migration toward non‑taxed channels and non‑taxed assets, and that such shifts could cut the revenue potential underlying the Commission’s projections.

Political dynamics could affect whether the levy moves forward. France has pushed for new EU revenue sources, while exchange‑heavy economies such as Malta have resisted measures seen as burdensome. Cyprus, holding the rotating Council presidency, plans to present a revised budget proposal around June 10; that timetable and the Commission’s Markets in Crypto‑Assets review consultation will influence whether the levy remains under consideration.

The Commission’s leaked figures are conditional on market behavior, regulatory uptake and the availability of fuller reporting data. With DAC8 reporting not fully in place until 2027 and unanimous Council agreement required, the final revenue outcome could differ from the current $23 billion projection.
