MDR Regulatory Frameworks Overview

Mandatory Disclosure Rules (MDR) are not a single global law—they are a network of coordinated regimes across jurisdictions. While the principles are aligned, each framework applies differently depending on geography and scope.

In this episode, we break down the three key MDR systems shaping global tax transparency.

🇪🇺 1️⃣ EU DAC6

The European Union framework is based on:

Directive (EU) 2018/822

🔍 What It Covers

• Cross-border tax arrangements within the EU

• Arrangements that meet specific “hallmarks”

• Both aggressive tax planning and certain standard structures

⚖️ Key Features

• Reporting obligation primarily on intermediaries

• Applies across all EU Member States

• Automatic exchange of reported information between countries

👉 DAC6 is one of the broadest and most widely enforced MDR regimes.

🇬🇧 2️⃣ UK DOTAS & MDR

The United Kingdom operates a dual system:

🧠 DOTAS (Domestic)

• Disclosure of Tax Avoidance Schemes (DOTAS)

• Focuses on UK domestic tax avoidance arrangements

• Long-standing regime with established enforcement

🌍 UK MDR (International)

• Targets offshore structures and CRS avoidance

• Aligned with OECD MDR principles

• Focuses on arrangements that:

• Circumvent CRS
• Obscure beneficial ownership

👉 The UK separates domestic vs international disclosure frameworks.

🌍 3️⃣ OECD Model Rules (Global Standard)

At the global level, MDR is driven by the

Organisation for Economic Co-operation and Development.

🎯 Purpose

• Provide a standardized framework for countries to adopt

• Target arrangements that:

• Avoid CRS reporting
• Conceal beneficial ownership

🔄 How It Works

• Countries implement the rules into domestic law

• Information is shared internationally

• Focus is on intermediaries and promoters

🎯 Key Takeaway

MDR operates on three levels:

• Regional (EU DAC6)

• National (UK DOTAS & MDR)

• Global (OECD Model Rules)

Despite differences, they share a common goal:

Expose tax planning early—especially where structures are designed to avoid transparency.
