Circle criticizes Germany's 50% crypto tax

TLDR

Circle has sharply criticized Germanys draft plan to tax 50% of crypto sale proceeds when investors cannot prove their purchase costs, calling it punitive for everyday users.

1. Germanys finance ministry has proposed a 50% substitute tax basis on undocumented crypto sales, but the figure and rules are still in draft and not yet law.
2. Circles Patrick Hansen says the scheme assumes a 100% profit on such trades, which would overtax even loss?making or low?profit transactions and hit retail users hardest.
3. Experts warn the proposal could create serious liquidity and compliance risks for self?custody users, pushing German crypto activity toward better documented venues or abroad if it is not softened.

Deep Dive

1. Draft Rule: 50% Of Proceeds

Germanys Federal Ministry of Finance has floated a crypto tax reform where, if a holder cannot provide credible evidence of their acquisition cost, tax would be calculated on 50% of the sale proceeds as a substitute assessment basis. In other words, the state would assume the purchase price was half the sale price and tax that assumed gain rather than the real one, with an effective 50% basis on proceeds in those cases. This framework is still at consultation stage and the 50% figure is explicitly not final, as noted by a German tax lawyer in coverage of the proposal. The measure would apply when documentation is missing, especially for coins moved from self?custody or foreign exchanges into German platforms, where proving purchase history is harder.

2. Why Circle Says It Is Harmful

Circles policy lead Patrick Hansen has publicly criticized the reform, arguing that it will hit normal consumers/investors particularly hard who lack perfect records or who bought recently with little profit or even losses, yet would be treated as if they doubled their money under the substitute rule. He points out that Bitcoin and other assets have underperformed over the past year, so assuming a 100% profit is unrealistic and would lead to overpayment of tax on many ordinary trades, according to his comments in Germanys crypto tax reform coverage. Tax specialist David Htzel adds that such a rule creates liquidity risk, because large tax deductions could be triggered even on small actual gains when assets move into German exchanges.

3. Implications For Crypto Users

For German crypto users, the immediate takeaway is that documentation becomes critical: full trade histories, wallet records, and proof of acquisition costs are the main defense against substitute assessments. The rule is still a draft and faces professional criticism, so changes in the percentage, scope, or safe?harbor options are possible as political debate continues and the finance ministry refines the proposal, as noted in reporting by Tokenpost. More broadly, it fits into a trend of tighter tax reporting and transparency on digital assets in Europe, meaning users should expect more scrutiny rather than less.

Conclusion

Germanys proposed 50% substitute tax on undocumented crypto sales has triggered pushback from Circle and tax experts because it decouples tax bills from actual gains and losses. If implemented in its current form, it could reshape how German investors store records, move assets, and choose venues, with strong incentives to keep impeccable documentation or shift activity to environments where the tax treatment is clearer and more proportional.
