What this risk is, and why it matters
The line between aggressive tax planning and tax evasion has narrowed significantly. The OECD BEPS framework, EU DAC reporting and equivalent national regimes treat structures that were defensible a decade ago as facilitation-of-tax-evasion offences. Personal-liability regimes for advisers and senior officers have tightened. Recent enforcement has hit transfer-pricing failures, treaty-shopping arrangements and disclosure-regime non-compliance with criminal-referral outcomes.
Legal and regulatory framework
BEPS Pillar 1 and 2, country-by-country reporting, mandatory-disclosure regimes (DAC6, equivalents), the UK Criminal Finances Act 2017 corporate offence of failing-to-prevent-facilitation, and US economic-substance doctrine apply across the cross-border tax-planning surface. Substance-over-form tests, GAAR application and beneficial-ownership transparency have all tightened. Recent enforcement has produced criminal prosecutions of advisers in addition to clients.
Typical scenarios and impact
Documented enforcement has produced transfer-pricing assessments in the ten-figure range against multinational firms, GAAR-driven structure unwinds, criminal prosecutions of tax directors and external advisers, and disclosure-regime fines for non-reporting of arrangements. Recent BEPS-driven assessments against tech and pharma firms have exceeded one billion dollars per case. Reputational damage has correlated with consumer-brand impact in some sectors.
Mitigation framework and when to engage an expert
Run an annual review of tax-structure positions against current regulator and case-law posture. Document substance evidence for any cross-border structure. Maintain DAC6 and equivalent disclosure-regime compliance with documented filing trails. Train finance and tax teams on facilitation-of-tax-evasion risk. Engage tax counsel for any new structure and for any material acquisition target's tax-position diligence; engage specialist transfer-pricing economists for benchmarking.
