DeFi Tax Gap: Europe’s Critical Loophole Faces Inevitable Closure, Warns Expert

PARIS, France – December 2025: The European Union’s deliberate exclusion of decentralized finance from its landmark crypto tax reporting framework represents a temporary concession to enforcement reality, not a permanent blind spot. According to former OECD official Colby Mangels, the structural gap allowing DeFi platforms to operate outside current transparency rules represents a closing window for the sector. Global anti-money laundering trends and coordinated international policy development signal that Europe’s DeFi tax gap won’t last forever.

DeFi Tax Gap Emerges from Enforcement Pragmatism

The European Union implemented its eighth revision of the Directive on Administrative Cooperation in late 2024, creating the first harmonized tax transparency framework for crypto assets across member states. DAC8 requires centralized crypto exchanges and custodians to begin collecting standardized user activity data starting in 2026. This framework deliberately excludes decentralized finance protocols from immediate reporting obligations, creating what appears to be a significant regulatory asymmetry.

Colby Mangels, Taxbit’s global head of government solutions and former OECD adviser who worked on the Crypto Asset Reporting Framework, explains this exclusion stems from practical enforcement considerations. “You really have to go to the intermediaries that are doing this as a business,” Mangels told Crypto News Insights. “It doesn’t make sense to go to your grandma and ask her to give you all the tax reporting on crypto just because you happened to work with her over a certain period.”

The CARF Implementation Timeline

The OECD’s Crypto Asset Reporting Framework represents the global standard for crypto tax transparency. As of December 2025, implementation follows this timeline:

• 48 jurisdictions committed to implementing CARF with first data exchanges by 2027
• 76 jurisdictions will implement CARF with data exchanges by 2029
• EU member states faced December 31, 2024 deadline to adopt DAC8 into national law
• Reporting obligations begin for centralized platforms in 2026

Global Crypto Tax Reporting Rebuilt from Ground Up

Traditional tax reporting frameworks proved inadequate for cryptocurrency markets. The Common Reporting Standard, implemented in the EU through DAC2, excluded most crypto activity entirely. This regulatory vacuum prompted the OECD to develop CARF specifically for crypto assets. The framework establishes clear parameters for who must report, what information gets collected, and how tax authorities exchange data internationally.

DAC8 essentially aligns European Union countries with CARF standards while allowing member states flexibility in implementation timelines. This alignment reflects broader global adoption patterns as dozens of jurisdictions prepare tax information exchange regimes. Mangels contrasts today’s digital environment with analog financial systems of thirty years ago. “If a client wanted to open a bank account in another jurisdiction, they had to take a suitcase of money, travel and talk to the bank at a physical location,” he recalled.

Modern crypto investors face dramatically different circumstances. They can theoretically access exchanges worldwide from their living rooms without notifying domestic tax authorities. “If I never tell my tax authority where I’m situated — for example, in France — and I never tell them about the money I made trading crypto on an exchange in Singapore, they won’t know. They’ll have no idea,” Mangels explained. DAC8 directly addresses this visibility gap for centralized platforms through standardized reporting requirements.

AML Enforcement Trends Signal Future DeFi Inclusion

While DAC8 and CARF focus specifically on tax reporting, their development intersects significantly with anti-money laundering frameworks. The Financial Action Task Force, which sets global AML standards, operates from the same Paris headquarters as the OECD. This physical proximity facilitates close collaboration between tax and financial crime policy development.

“An interesting fact to know is that the FATF sits in the same offices as the OECD, so you can literally go down the hall or have a coffee with folks there,” Mangels noted, highlighting institutional relationships that influence regulatory design. Tax authorities frequently reference AML frameworks when designing reporting regimes, particularly for definitional clarity around regulated entities.

Current DeFi Regulatory Landscape

A June 2025 FATF report revealed regulators continue struggling to identify controlling parties within decentralized finance ecosystems. The findings demonstrate the enforcement challenges underlying DeFi’s current exclusion from tax reporting:

• 47 of 99 jurisdictions with advanced crypto rules require certain DeFi platforms to register as virtual asset service providers
• Only 12 jurisdictions have identified at least one unregistered DeFi platform meeting VASP criteria
• Just 4 jurisdictions reported registering or licensing DeFi entities as VASPs

These statistics illustrate why tax authorities initially focused reporting obligations on identifiable intermediaries operating as businesses. Most DeFi protocols lack centralized operators and custodial relationships that facilitate traditional enforcement approaches.

Jurisdiction Shopping Faces Mounting Pressure

As DAC8 takes effect across the European Union in 2026, compliance burdens initially concentrate on centralized exchanges and custodians. However, tax authorities monitor anti-money laundering developments closely, recognizing that VASP classification models could eventually expand reporting obligations throughout crypto markets.

The OECD maintains particular focus on preventing regulatory arbitrage through jurisdiction shopping. Mangels described tracking crypto service provider relocations during his OECD tenure. “As new crypto centers are developed or come online, they will also be expected to comply with the OECD standards,” he stated. While the organization lacks direct enforcement authority, jurisdictions remaining outside international standards face mounting reputational and financial pressure.

FATF scrutiny compounds this pressure significantly. As more economies align tax and AML rules around shared definitions and reporting standards, opportunities for regulatory arbitrage diminish steadily. This convergence creates inevitable momentum toward comprehensive DeFi inclusion in transparency frameworks.

The Enforcement Evolution Timeline

Tax authority approaches to cryptocurrency regulation follow a predictable evolution pattern:

1. Initial Phase: Focus on identifiable centralized intermediaries with clear jurisdictional presence
2. Expansion Phase: Incorporate lessons from AML enforcement and technological developments
3. Maturation Phase: Develop specialized approaches for decentralized and pseudonymous systems
4. Integration Phase: Achieve comprehensive coverage across all crypto asset categories

Structural and Geographic Gaps Narrow Simultaneously

DeFi’s current exclusion from tax reporting frameworks reflects both structural characteristics and geographic enforcement limitations. The absence of centralized operators presents unique challenges for traditional regulatory approaches. Simultaneously, cross-border visibility gaps enable jurisdictional arbitrage opportunities that complicate comprehensive oversight.

Both the OECD and FATF signal these gaps represent temporary features rather than permanent exemptions. Their coordinated policy development, shared physical headquarters, and integrated approach to financial transparency create inevitable momentum toward DeFi inclusion. Technological solutions for identifying controlling parties in decentralized systems continue advancing alongside regulatory frameworks.

Mangels emphasized that mainstream crypto adoption brings inevitable tax scrutiny for assets once ignored by authorities. The community confronts this reality as regulatory frameworks mature globally. What begins as focused enforcement on centralized intermediaries naturally expands toward comprehensive coverage as technical capabilities and international coordination improve.

Conclusion

Europe’s DeFi tax gap represents a deliberate enforcement prioritization rather than a permanent regulatory exemption. The exclusion of decentralized finance from DAC8 and CARF frameworks reflects practical realities about identifying reporting entities and collecting verifiable data. However, close collaboration between tax and anti-money laundering authorities, combined with technological advancements and international coordination, ensures this gap will close progressively.

As centralized platforms prepare for 2026 reporting obligations under DAC8, DeFi protocols operate within a narrowing window of regulatory exclusion. The structural characteristics that currently complicate enforcement will inevitably be addressed through evolving frameworks and technological solutions. Europe’s DeFi tax gap won’t last forever because international standards development, AML enforcement trends, and jurisdictional pressure create inexorable momentum toward comprehensive transparency.
